Weblogic 7.0 deploy exception and Connection Pooling

Question

Hi,
I am using weblogic 7.0
When I delpoy my application in the server I get the following exception when deployed through webLogic builder deploy tool
<Aug 24, 2004 1:26:32 PM IST> <Error> <Deployer> <149201> <The Slave Deployer failed to complete the deployment task with id 0 for the application MyApp.
weblogic.management.ApplicationException: No modules to prepare on myserverfor application named MyApp
at weblogic.j2ee.J2EEApplicationContainer.prepare(J2EEApplicationContainer.java:545)
at weblogic.management.deploy.slave.SlaveDeployer.processPrepareTask(SlaveDeployer.java:1062)

at weblogic.kernel.ExecuteThread.execute(ExecuteThread.java:213)
at weblogic.kernel.ExecuteThread.run(ExecuteThread.java:189)
but
then when I invoke the application the application is successfully executed
My application.xml file
is like
<application>
<display-name>MyApp</display-name>
<module>
<web>
<web-uri>MyApp.war</web-uri>
<context-root>MyApp</context-root>
</web>
</module>
</application>
weblogic.xml has following
<weblogic-web-app>
<reference-descriptor>
<resource-description>
<res-ref-name>jdbc/MyApp</res-ref-name>
<jndi-name>jdbc/MyApp</jndi-name>
</resource-description>
</reference-descriptor>
<charset-params>
</charset-params>
</weblogic-web-app>
in weblogic-application.xml file
<weblogic-application>
<data-source-name>MyApp</data-source-name>
</weblogic-application>
web.xml has
<resource-ref>
<res-ref-name>jdbc/MyApp</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
under the

now in DAO source Code
try {
icCtx = new InitialContext(); // Instantiate the InitialContext Object
// Lookup the Datasource using the DBName
strDbName = "java:comp/env/jdbc/MyApp";
dsObject = (DataSource) icCtx.lookup(strDbName);
connObject = dsObject.getConnection(); // Get the Connection
connObject.setAutoCommit(false);
System.out.println("Conn established" +connObject );
} catch (Exception e) {
Now when I invoke My Application as
http://localhost:7001/MyApp/HomePage
I get
Conn establishedweblogic.jdbc.rmi.SerialConnection@71d8c0
Conn establishedweblogic.jdbc.rmi.SerialConnection@2cfbaf
Conn establishedweblogic.jdbc.rmi.SerialConnection@5a739d
Conn establishedweblogic.jdbc.rmi.SerialConnection@4d42cf
different Adrress Meaning Connection Pooling is Not working.
Where are the possible mistakes being done?Why I am not getting the same connnection and why is there an Exception in Deployment?
Can somebody help me out?

Answer 1

DAO Code
connObject = dsObject.getConnection(); // Get the Connection
connObject.setAutoCommit(false);
System.out.println("Conn established" +connObject );
} catch (Exception e) {
Now when I invoke My Application as
http://localhost:7001/MyApp/HomePage
I get
Conn establishedweblogic.jdbc.rmi.SerialConnection@71d8c0
Conn establishedweblogic.jdbc.rmi.SerialConnection@2cfbaf
Conn establishedweblogic.jdbc.rmi.SerialConnection@5a739d
Conn establishedweblogic.jdbc.rmi.SerialConnection@4d42cf
different Address Meaning Connection Pooling is Not working.
How do I can be sure that the connection pool is working?
