jboss-as-7.1.1 deploy error

[milind_cm]

I am trying to deploy an application which was working in JBoss 4.2 into Jboss 7.1.1. Managed to get around few initial problems but stuck at the following problem. Any clues/ideas will be very helpful..Thanks in advance.

This happens while code tries to get connection from the datasource which is configured correctly and tested. Using jdk1.7.

How do you connect the database? If this is in your code you might need to add a dependency to the java.nio module.

But the recommended way is to use a datasource and the connection pool.

[milind_cm]

Thanks a lot for the response.

I am indeed using the datasource and getConnection() method on it. Similar to the following:

DataSource ds = (DataSource) ctx.lookup("java:/dname");
Connection con = ds.getConnection();

The datasource is configured correctly and I get the following log at the startup.

Datasource is org.jboss.jca.adapters.jdbc.WrapperDataSource@16ca8de

I think it is a basic stuff and probably may not need any additional dependancies...But not sure why java.nio is coming to into picture in the first place....

[wdfink]

Ok,

that is very basic and should work without having a dependency to your app.

Do you follow the DS wiki? How do you install the Oracle driver, as module or deployed?

Do you use 'jboss/datasource/MyDS' as the dname or something different?

I never saw such problem.

[nickarls]

There is some cipher references in the stacktrace. Are you using a signed driver jar?

Thanks again to both of you for responding.

Just thought of posting what I found - may be it's useful to somebody else...

I got around this error by simply removing a jar file from my web application's library (I started thinking in this direction after Nicklas's post above). The jar file I removed as "jsafejce.jar". I feel that for some reason, Oracle driver (yes, I am using the module configuration etc as required for Jboss 7) is trying to use encryption if this jar exists in application's classpath..When I remove this, the application was able to get the database connection and got the data from the database...

Thanks again,

Regards,
