General Questions

1. How to know the detailed version information of HXTT Word package?
1st way: "java com.hxtt.sql.word.WordDriver" will print that information.
2nd way: check that MANIFEST.MF file in jar file.
3rd way: Class.forName("com.hxtt.sql.word.WordDriver").newInstance().toString(); 4rd way: DriverManager.getDriver( url ).toString()

2. Why that package file is more than 19MB?
The file size of HXTT JDBC package is less than 2MB, and it's using two engines to parse MS Word document. One is from HXTT Excel package, but another is Apache POI4.0.1, which contains at least 9 jar fils at here. To avoid the classpath setting issue, that 9 jar files has been zipped into our jar file. Considering transaction support, we're planing to remove code for POI package, and using only the engine from HXTT Excel.

3. What is difference between the HXTT Word Package, Embedded Package, and Remote Access Package? Can I get some sample code to use the HXTT Word?
The HXTT Word supports Embedded and Remote Access. HXTT Word Package includes a Database GUI manager. If you're accessing the local data, you can use the HXTT Word Package or Embedded Package. If you're accessing the remote data, you can use the HXTT Word Package or Remote Access Package. There is no any difference for your code to use anyone of three packages. Please download the demo package from here.

4. What causes the 'No suitable driver' SQLException?
This error usually occurs during a call to DriverManager.getConnection(). The cause can be failing to load the appropriate JDBC driver before calling getConnection(), or specifying an invalid JDBC URL that isn't recognized by your JDBC driver. If you're using a trial version, you will get "No suitable driver" SQLException, and "Evaluation period over" after using about 30 days. The HXTT Word driver's name is com.hxtt.sql.word.WordDriver, and its JDBC URL:

                jdbc:word:[//]/[DatabasePath][?prop1=value1[;prop2=value2]] (You can omit that "//" characters sometimes)
                        For example:
                                "jdbc:word:////usr/data" for unix or linux:
        Access by Word Server: Skip it if you don't use TCP, RMI or JINI.
                        For example: "jdbc:word://domain.com:3099/c:/data" if one WordServer is run on the 3099 port of domain.com

5. How to setup Word url on the Novell Server?
Word driver can run on Novell server. You can use directly access or WordServer to visit your data on Novell server. If your Word files is at sys:/java/yourdata, the direct URL should be:

6. I got "java.io.IOException: Permission denied" sometimes for my SELECT query.
Please figure out what directory Java's java.io.tmpdir system property points to, and make sure that directory is writable by the user that runs your Java applications, otherwise you should set tmpdir properity in Connection properity to a writable directory. tmpdir properity indicates whether set a temp directory, Default: the value of JVM's "java.io.tmpdir" property. If that value is incorrect, using the directory of JDBC url.

7. When I used jdbc:word:/<DatabasePath>, the connection's schema was empty. "create catalog if not exists wordfiles". What is Catalog?
Word's schema is always empty. You can use catalog to query subdirectory. Catalog means a directory, which contains some Word files.

Applet Questions

1. I already configured the .java.policy for my applet, but I continue with problems of "acess denied".
For instance, you're using "jdbc:word:/C:/test", and grant codeBase "file:/C:/test" in your policy file, but your applet is running from "D:\sample\CargaStatApplet.html". You should grant codeBase "file:/D:/sample", not "file:/c:/test".

2. http://localhost:8080/jdbcapplet.html, the applet started but returns a Classnotfound com.hxtt.sql.word.WordDriver error in the gui list.
Please add a codebase tag. For instance, "<applet code="jdbcapplet.class" codebase="Word_Remote_Access_JDBC40.jar"></applet>". The Word_Remote_Access_JDBC40.jar should be at the same directory of jdbcapplet.html.

Remote Access Questions and Client/Server Mode Questions

1. Client/Server mode question: The data directory is not in the IBM machine where the Java program should run, but instead those Word files are in another machine with Windows operating system.
com.hxtt.sql.admin.Admin provides a GUI manger for Word server. For instance, you wish to provide JDBC4.0 remote data access. Please use "java -cp yourdirectrory/Word_JDBC40.jar com.hxtt.sql.admin.Admin" to start GUI manager, and add a url setting of '"jdbc:word://" + 8029 +"/"+databaseDirectory' on your host of an IP sample), then click Start button. Third, you can use 'String url =
"jdbc:word://" + 8029 +"/"+databaseDirectory;' to visit your Word database from your IBM machine. If you're running that GUI manager on "yourNT.com" host to visit "c:/database" directory, you can use "jdbc:word://yourNT.com:8029/c:/database" on your web application. jdbc:word://yourNT.com:8029/c:/database?user=oneuser&password=onepassword can provide a simply user/password verification for client/server mode. If you wish to write a secure Word server for some sensitive information, embedded encrypt/decrypt functions can help you.

2. Remote access through map network drive question: How to remote access Word data without WordServer?
You can share your remote directory which contains your data files, then map it to a local driver.
For Windows: You can connect remote Word database by sharing the directory and map it to local drive. You should disable the OPLOCKS of your Samba/NT/2000 server. How to turn off opportunistic locking in windows on client and on server side? This is done by manipulating the following registry key:

For client side: oplocks.reg file

For server side: oplocksServer.reg

You should put additional registry entry like e.g.
The following registry entries disable opportunistic locking and caching:
HKey_Local_Machine \ System \ CurrentControlSet \ Services \ LanmanServer \ Parameters \ EnableOpLocks must be set to 0.
HKey_Local_Machine \ System \ CurrentControlSet \ Services \ LanmanServer \ Parameters \ CachedOpenLimit must be set to 0.
HKey_Local_Machine \ System \ CurrentControlSet \ Services \ LanmanWorkStation \ Parameters \ UseOpportunisticLocking must be set to 0.
HKey_Local_Machine \ System \ CurrentControlSet \ Services \ LanmanWorkStation \ Parameters \ UtilizeNtCaching must be set to 0. 

For Linux: You can use mounting. One user uses Samba to maped NTFS partitions in Linux servers, and Word driver works normally like mapping any mount point in Linux.
For Novell: You can map NCP directory as driver or mount NCP directory.

3. Remote access through UNC path question: Can I setup only one datasource to access four servers for my Cold Fusion?
To access one unc path, you can use jdbc:word:/\\PC17\c$\values or jdbc:word:/\\PC17\val.
To access four unc pathes in the same connection, you need to use a free JDBC url, "jdbc:word:/" or "jdbc:word:///". Then you can use some full UNC path names in SQL to visit your four servers where your Java VM has right to access.. For instance:

  select * from \\amd2500\e$\wordfiles\test;
  select * from "\\amd2500\d$\wordiles".test;
  select * from ".".test;

4. Remote access through http/https/ftp protocol question: How to let my program to fetch data daily from our web host?

You need to use url database, which supports http protocol, https protocol, ftp protocol, and sftp protocol.

5. Remote access through SAMBA protocol question: How to let my servlet on Linux to access over 300 hundred shared folders that all are on Windows boxes

You need to use SAMBA table, which needn't to map or mount driver.

6. I can't get the com.hxtt.sql.admin.Admin runnig for internet --> intranet
HXTT Word supports port mapping and NAT route. Let HXTT Word listening a port on the database server, and modify your route table or NAT table to map an external port to that internal port. You can use "start java -Djava.security.policy=policy com.hxtt.sql.admin.Admin" to start GUI manager. You should add a remote url, for instance, jdbc:word://localhost:8029/d:/wordfiles, and click Start button to start that server. Then on your internet client side, you can use jdbc:word://externalIP:8029/d:/wordfiles to access your intranet host. externalIP means an external IP or domain name address of your gateway or database server.
BTW, except for TCPServer protocol, HXTT Word can use also RMIServer protocol. For instance, you have used "start rmiregistry 1099 -J-Djava.security.policy=yourPolicyFile" to startup your rmi service. Then you can use jdbc:word://localhost:1099/d:/wordfiles?serverType=RMIServer to let HXTT Word bind remote service in registry. The key is use "java -Djava.security.policy=policy -Djava.rmi.server.hostname=externalIP com.hxtt.sql.admin.Admin RMISERVER 8029" to start your server. RMIServer protocol is slower much than the default TCPServer protcol.

7. I would like to start a server (TCP) from our application, instead of DBAdmin. I need to be able to programmatically tell the application which profile to start.
Please read Start/Stop Server Programmatically.

8. Is there a way to specify a file path in the url that will connect to a mapped drive in Windows 2000. ie drive \\gomer\pyle\db which is mapped to f drive on the server.
Word driver can work with mapped driver, and you should use "jdbc:word:/f:" to access your data.

Note: If you're using a database file through a UNC path or a mapped drive of Windows, there is a Windows Security restriction. If you run ColdFusion (Tomcat, or tanuki sw wrapper) as a service on Windows, it operates by default as System, and cannot access directories on a remote system or mapped drive; to resolve this issue, do not run ColdFusion (Tomcat, or tanuki sw wrapper) using the local system account.

9. When I click Start button to start a remote service, I get a security excaption: access denied (java.net.SocketPermission connect,resolve)
You have to enable java.net.SocketPermission right in your policy file if you
run a Word server. Please read
file:///yourdriver|/jdk1.6/docs/guide/security/PolicyFiles.html for more
information about policy file. It is unnecessary to know the specific content
of a policy file, since you can use policy tool to create and maintain your
policy files. Please read
file:///yourdriver|/jdk1.6/docs/tooldocs/win32/policytool.html for policy tool.

10. How to start remote service as MS Windows service and Linux(Solaris) Daemon?
Please read Run HXTT WordServer as Windows Service or Linux(Solaris) Daemon.

11. How to start remote control when WordServer is running as Windows service or Linux(Solaris) Daemon?
You can use "java com.hxtt.sql.admin.Admin TCPCLIENT [host:]port [remoteControlPassword]" to start your remote control.

SQL Questions

1. How to return text content for a MS Word file?
"select STRING_AGG(text,'\r\n') as content from testdoc.pageparagraphs;" will return the content for paragraphs in testdoc file.
"select STRING_AGG(text,'\r\n') as content from testdoc;" will return all content(paragraph, table, header, footer) for testdoc file.

2. How to fill a table in a MS Word file?
You can use tables(__child__1, __child__2,... as column name), vtables(vertical table, first row as column names), htable(horizontal table, first column as column names),celltable( cell table, every cell become a data row). "select *,text from testpdf.vtable1;" will return all text content information in the first table file.
You can use
update testpdf.vtable1 set __child__1=?,__child__2= where __child__1=? and recno()=?; to set any content
create table if not exist testdoc.vtable1 select __children__ from anotherfile.vtable1;
to a table from another document.

3. How to cldear content in a MS Word file?
delete from testword.paragraph3; /* become a blank paragraph */
truncate table testword.paragraph2;/* become a blank paragraph */
truncate table testword.paragraphs;/* clear all paragraphs */

Concurrence Questions

1. Does HXTT Word support multi-user access?
The HXTT Word supports multi-user access.

Interoperability Questions

1. How to set up HXTT Word with Tomcat4.1 as PoolableConnection?
This sample shows three PoolableConnections ways through Database Connection Pool (DBCP) Configurations and JNDI Resources( You should read JNDI Datasource HOW-TO and JNDI Resources HOW-TO also.):
In server.xml:

<Context path="" docBase="ROOT" debug="5" reloadable="true" crossContext="true">

    <Resource name="jdbc/testwordPool1" auth="Container" type="javax.sql.DataSource"/>	
	<ResourceParams name="jdbc/testWordPool1">

    <Resource name="jdbc/testWordPool2" auth="Container" type="com.hxtt.sql.HxttConnectionPoolDataSource"/>	
	<ResourceParams name="jdbc/testWordPool2">


    <Resource name="jdbc/testWordPool3" auth="Container" type="com.hxtt.sql.HxttConnectionPoolDataSource"/>	
	<ResourceParams name="jdbc/testWordPool3">


Then you can use the below code to test those PoolableConnections:

	Context initContext = new InitialContext(); 
	Context envContext = (Context)initContext.lookup("java:/comp/env"); 
	DataSource ds1 = (DataSource)envContext.lookup("jdbc/testWordPool1"); 
	Connection conn1 = ds1.getConnection();
	out.println("testWordPool1 OK:)<br/>");
	Statement stmt1 = conn1.createStatement();
	ResultSet rs1 = stmt1.executeQuery("select * from test");
	DataSource ds2 = (DataSource)envContext.lookup("jdbc/testWordPool2"); 
	Connection conn2 = ds2.getConnection();
	out.println("testWordPool2 OK:)<br/>");
	Statement stmt2 = conn2.createStatement();
	ResultSet rs2 = stmt2.executeQuery("select * from test");
	DataSource ds3 = (DataSource)envContext.lookup("jdbc/testWordPool3"); 
	Connection conn3 = ds3.getConnection();
	out.println("testWordPool3 OK:)<br/>");
	Statement stmt3 = conn3.createStatement();
	ResultSet rs3 = stmt3.executeQuery("select * from test");

If you use org.apache.commons.dbcp.BasicDataSource, but get "Cannot create PoolableConnectionFactory" Error, you should check your commons-pool-1.x.jar and commons-dbcp-1.*.jar file in $TOMCAT/common/lib directory to see whether two files have the same version. DBCP v1.2 requires Pool v1.2 so that you should update Pool v1.1 from the tomcat website.

If you wish to add more Connection properity, you should use connectionProperties, for instance:


2. How to set up HXTT Word with vqServer 1.9.55 as web server?

6. Enter the datasource information. JDBC URL is always in the format jdbc:word:[//[host:port]]/[DatabasePath], for instance jdbc:word:/c:/data. You can set more connection properties in your JDBC URL, for instance: jdbc:word:/c:data?delayedClose=15;maxCacheSize=6144;lockTimeout=2000; . Driver class is always com.hxtt.sql.word.WordDriver. Driver name is used to identify the driver in the datasources view, and you can use Word. Username and password are not required. They can also be specified in the cfquery tag (but datasource verification will fail if you don't enter them). Description is not required.
7. Lastly, please press "Submit" to finalize the entered data.
8. You can find edit.cfm and edit_action.cfm sample in demo pacakge.

4. HXTT Word with If you run ColdFusion (Tomcat, or alexandria sw and tanuki sw wrapper) on Windows 2000 and Windows XP Pro does not work on mapped drives.

Note: If you're using a database file through a UNC path or a mapped drive of Windows, there is a Windows Security restriction. If you run ColdFusion (Tomcat, or tanuki sw wrapper) as a service on Windows, it operates by default as System, and cannot access directories on a remote system or mapped drive; to resolve this issue, do not run ColdFusion (Tomcat, or tanuki sw wrapper) using the local system account.

The service(For instance, ColdFusion MX Application Server, ColdFusion MX 7 Application Server, or Apache Tomcat) built by ColdFusion (Tomcat, or tanuki sw wrapper) can not access the share directory at other machine by default. But you can do as follows to solve this problem:
1. Right click the service built by ColdFusion (Tomcat, or tanuki sw wrapper) in service manager, and click the property menu.
2. On the open window,select the login tab, click this account radio box, and click the browse button.
3. Select the administrator account(it seems that you should select the administrator account), input the correct password in the password textbox and confirm password textbox.
4. Restart this service, you can find this service can access the share directory at other machine.

5. How to resolve 'DataSet has no unique row identifiers.' issue in JBuilder's QueryDataSet?
You can use __rowid__, a virtual column to avoid that issue, For instance:

Now you need to copy the driver (the Word_JDBC40.jar file) to the classpath of your application server to enable JasperServer to find it.
In general it's best to copy the driver to the application server's shared library location. Refer to your application server documentation for exact locations.
For example in a JapserServer Bundle install on windows this is located at: C:/Jaspersoft/jasperreports-server-cp-7.1.0/apache-tomcat/lib
After these modifications you will need to restart the application server for this settings to take effect. For information on restarting your server see Chapter 3 of the JasperReport Server Install Guide (is located on the /docs folder of your Jasper Server install path)
1. Log into JasperReport Server from your browser using the jasperadmin or superuser account (e.g.: http://localhost:8080/jasperserver-pro)
2. Go to View | Repository, Select a folder where you want to create your Data Source (e.g.: /Data Sources). Right click on the folder name in the repository view and from the context menu select called Add Resource and then click on Data Source. Now you are presented with a screen to enter the settings of your Data Source connection
3. Type choose JDBC Data Source. JDBC Driver option choose Other... .

you can use
Sql2o sql2o = new Sql2o(url,null,null,new HxttQuirks());
import org.sql2o.quirks.NoQuirks;
public class HxttQuirks extends NoQuirks {
public HxttQuirks() {
public HxttQuirks(Map converters) {
public String getColumnName(ResultSetMetaData meta, int colIdx) throws SQLException {
return meta.getColumnName(colIdx);//Sql2o is using meta.getColumnLabel, but JDBC specification will use tableName.column for getColumnLabel when there is column name collision.
