Hi Everyone,

my application with same code and abc-ds.xml is working fine on Jboss 4.0.5 but if i am deploying it on 4.2.3, i get some error in my login page, i found root cause to be:

getting ds=NULL in following line




i get output as:
2
3
DS is Null


my abc-xml.ds is as follows: (userid and password , all data in the datasource are correct)



but if i am using


instead of connecting via jndi, its getting connected and application is working fine.

Please, reply if you have any clue.
NOTE: my abc is getting bounded in both Jboss, but giving NULL in Jboss 4.2.3

Are you packaging any JBoss specific jar files in your application (for ex: jboss-common-core.jar). If yes, remove them from your application packaging.

It's a typical classloading issue, although in this case it doesn't result in the usual ClassCastException. More on classloading issues can be found here

 
It is sorta covered in the JavaRanch Style Guide.
