Hi,

I am using Eclipse, Java 5, Tomcat 5.5, MySQL and SQL Server 2005.

When I start the server I get this error in log file:

Seems more like your configuration couldn't be loaded. Have you checked, that the configuration file can be found and loaded?

With 'configuration' I meant your definition of the datasource in your applicationcontext.xml (assuming you are using spring), something like:

If those values are correct and available to your application

Hi Joachem,

Thanks for your reply. Looks like your reply is bringing me closer to the solution.

Yes we are using Spring and iBatis.
Here is the sample entry from applicationContext-ibatis.xml:

<!-- Data Sources for database interactions: all JNDI currently -->
<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName">
<value>java:comp/env/jdbc/DBtest</value>
</property>
</bean>
Here is the entry in my server.xml:

<Resource auth="container" name="jdbc/DBtest" type="javax.sql.DataSource"/>
<ResourceParams name="jdbc/DBtest">
<parameter>
<name>driverClassName</name>
<value>com.mysql.jdbc.Driver</value>
</parameter>
<parameter>
<name>url</name>
<value>jdbc:mysql://localhost/test</value>
</parameter>
<parameter>
<name>username</name>
<value>root</value>
</parameter>
<parameter>
<name>password</name>
<value>admin</value>
</parameter>
<parameter>
<name>factory</name>
<value>org.apache.commons.dbcp.BasicDataSourceFactory</value>
</parameter>
<parameter>
<name>maxActive</name>
<value>5</value>
</parameter>
<parameter>
<name>maxIdle</name>
<value>3</value>
</parameter>
<parameter>
<name>maxWait</name>
<value>10000</value>
</parameter>
</ResourceParams>

Do you think if the entry in ibatis.xml has something wrong or mismatched?

Thanks,

Ankur

I dont think its the problem with spring or iBATIS.

I created another project with just tomcat, eclipse, struts and mysql and i am getting the same error:
