Problem deploying an entity bean

[Ram Pra]

Hello,
I get the exception shown below when I try to deploy an entity bean.CXould some one tell me the complete procedure to deploy an entity bean.
I read somwhere that I should configure the datasource before deployment.What does he exactly mean by that.
Why am I getting the exception???
Exception:

hi,
You have to specify the datasource for the entity bean from the datasource tab in WAS when u deploy it, i think yhe error you are getting is because of that only, do confirm that.

Hi sidhu,
I really didn't get you,if you could explain it to me in detail what should be doing to specify the datasource ,it would be very nice of you.Bcoz as u said ,when i right clicked on the datasource tab,i saw the path to the default datasource "D:/WebSphere/AppServer/bin/myidb.prp".
Could you pls explain it to in detail..
Thanks

Hi Prashanth,
Well ok heres what u need to do to deploy an entity bean in Websphere app server,
First you would have created that bean from visual age , there u map it to the database using schema and maps from the tools available there,
Generate the deployed code of your bean, then export the deployed code jar file to a location, say in ur was folder to deployable jars,
then start was, now first go to types tab, before that i am assuming you have the database table in place and the database driver loaded in was(if not do so from types tab itself) .
Now in types tab select a new datasource, specify the driver, i am using COM.ibm.db2.app.DB2Driver for DB2, you can find its jar file in db2zip file which is in sqllib/java folder...
Now when u have selected datasource select the driver and database( the one which has ur table ) etc.and create it.
then go to topology, first thing you do there is expand ur tree and try to find the name of datasource uve just created.
Right click on it to install it.
then u go to the default container( or the ejb container if uve made ur own application) right click there and then create ejb, give the jndi name, selece the jar file by browsing- and double click on the jar file - select the *.ser file which appears,
then go to the datasources tab there if uve installed the datasource select it from the list, then simple create it,it should work now.
Hope that this will help you, if you still have problems with it, get back to me, ill try to figure it out.
Cheers..

by the way one thing ,all that i told you above is to be done in websphere app server admin console just for the sake of telling.

Hi friends,
Now im working with VisualAge and WebSphere with Db2.
Im finding difficult in deploying my entity bean in WAS.
I'm using "com.ibm.db2.jdbc.app.DB2Driver" as my deiver and i used "db2java.zip" for installing the driver.
But still im getting driver not found error while starting the container.
Pls can any one one give me the result.
Thanks in advance
