note The full stack trace of the root cause is available in the Apache Tomcat/5.0.28 logs.
I deploy the .war to application server and it works just fine.
and i configure the tomcat with:
JNDI Name: jdbc/test
Data Source URL: jdbc:mysql://192.168.0.2:3306/test
JDBC Driver Class: org.gjt.mm.mysql.
User Name: root
Password: admin
Max. Active Connections: 20     
Max. Idle Connections: 20
Max. Wait for Connection: 5000
the only thing different in application server is the the Jdbc Driver Class.
And I am using Creator update 7 to generate the .war
am i missing something ????

Answer 1

I found a simple way to deploy on Tomcat.
*** Copy standard.jar, jstl.jar and mysql-connector-xxx.jar (if you are using mysql otherwise the drivers jar for the DB you are using).
*** Edit the Tomcat conf/context.xml config file and add a WatchedResource :
<WatchedResource>META-INF/context.xml</WatchedResource>
*** Add your context.xml to META-INF of your war :
<Context path="/DBTest" docBase="DBTest"
        debug="5" reloadable="true" crossContext="true">
  <Resource name="jdbc/TestDB" auth="Container" type="javax.sql.DataSource"
               maxActive="100" maxIdle="30" maxWait="10000"
               username="javauser" password="javadude" driverClassName="com.mysql.jdbc.Driver"
               url="jdbc:mysql://localhost:3306/javatest?autoReconnect=true"/>
</Context>This will create a config file in conf/Catalina/localhost with the context path name, so in this case DBTest.xml
Hope that helps! That's how I got it working...
