hi all, the followings are all the codes. Problem is when i use DriverManger i am able to insert into database but when i use struts datasource configuration i am not able to insert into database. It is not showing any error but data isnt inserting into database.

I am using struts 1.2.9 netBeans 6.1 mysql database and appropriate driver.

1)struts-config.xml

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE struts-config PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 1.2//EN"
"http://jakarta.apache.org/struts/dtds/struts-config_1_2.dtd">
<struts-config>
<data-sources>
<data-source type="org.apache.tomcat.dbcp.dbcp.BasicDataSource"
key="userDB">
<set-property property="driverClassName"
value="com.mysql.jdbc.Driver" />
<set-property property="url"
value="jdbc:mysql://localhost:3306/NewUser" />
<set-property property="username" value="root" />
<set-property property="password" value="root" />
<set-property property="defaultAutoCommit"
value="false" />
<set-property property="defaultReadOnly"
value="false" />
<set-property property="validationQuery"
value="SELECT COUNT(*) FROM user" />
</data-source>
</data-sources>
<form-beans>
<form-bean name="UserRegistrationForm" type="com.tutorial.ActionForm.UserRegistrationForm"/>
</form-beans>
<global-exceptions>
</global-exceptions>
<global-forwards>
</global-forwards>
<action-mappings>
<action path="/userRegistration"
type="com.tutorial.Action.UserRegistrationAction"
name="UserRegistrationForm"
input="/userRegistration.jsp">
<forward name="success" path="/regSuccess.jsp" />
</action>
</action-mappings>
<controller processorClass="org.apache.struts.tiles.TilesRequestProcessor"/>
<message-resources parameter="com/myapp/struts/ApplicationResource"/>

<!-- ========================= Tiles plugin ===============================-->
<!--
This plugin initialize Tiles definition factory. This later can takes some
parameters explained here after. The plugin first read parameters from
web.xml, thenoverload them with parameters defined here. All parameters
are optional.
The plugin should be declared in each struts-config file.
- definitions-config: (optional)
Specify configuration file names. There can be several comma
separated file names (default: ?? )
- moduleAware: (optional - struts1.1)
Specify if the Tiles definition factory is module aware. If true
(default), there will be one factory for each Struts module.
If false, there will be one common factory for all module. In this
later case, it is still needed to declare one plugin per module.
The factory will be initialized with parameters found in the first
initialized plugin (generally the one associated with the default
module).
true : One factory per module. (default)
false : one single shared factory for all modules
- definitions-parser-validate: (optional)
Specify if xml parser should validate the Tiles configuration file.
true : validate. DTD should be specified in file header (default)
false : no validation

Paths found in Tiles definitions are relative to the main context.

I would recommend that you not use the Struts DataSource utility. It's listed as deprecated in version 1.2.9, and has been removed entirely from version 1.3. For more information on what to use instead, see question 7 of our FAQ.
