java.lang.ClassCastException: com.ibm.ws.rsadapter.jdbc.WSJdbcDataSource

| Through various Google searches, I've seen several references to the ClassCastException that is the subject of this thread. Unfortunately, I haven't seen a solution that cures the exception yet.
I'm not using any EJBs, just SQL in a class, using a datasource.
I've configured the datasource on the PortalServer (AIX 5.1 machine) exactly as it's configured in the test environment in WSAD, but no luck.
Can anyone help?
Thanks,
Andy | |

| Did you find a solution for this? It seems we have the same problem when
lookup for the datasource defined at the WAS level (with a WPS)
Thank you,
Gabriela

| Hi,
I had the same Exception.
The problem was that I had the Oracle Driver (classes12.zip) included in my EAR File. When I removed it from the EAR file (the Oracle Driver was then only referred to in the JNDI definition of my datasource), then it worked well.
regards
Stefan | |

| There might be a problem whith datasource. There is an option "Use this datasource in Container managed persistance (CMP)" for predefined datasource.
We had the same exception trying to start our EAR. After we switched on the option, application successfully started.

| I haven't seen the entire stack trace, so I'm grasping at straws here: Did you properly reference your DataSource in the ibm-web-bnd.xmi file? In RAD, you can add resource references by editing your web deployment descriptor and clicking on the "Referen
ces" tab at the bottom of the view. Then just click "Add..." and select "Resource Reference" or "Resource Environment Reference" as appropriate.

| Hi,
I am facing a similar problem and i am not able to solve it .
The code is
private final static String DATASOURCE_NAME = "jdbc/MyDataSource";
private DB2DataSource dataSource;
// Create a starting context for naming operations
InitialContext registry = new InitialContext();
//dataSource = (DB2DataSource) registry.lookup(DATASOURCE_NAME);
// instead of doing at 1 go , have done it in 2 steps
java.lang.Object obj = registry.lookup(DATASOURCE_NAME);
dataSource = (DB2DataSource) obj;
here when I am casting the object to a DB2DataSource it is giving
"java.lang.ClassCastException: com.ibm.ws.rsadapter.jdbc.WSJdbcDataSource" error
when I change the DB2DataSource to plain DataSource ..it is working fine .
I need the DB2DataSource object explicitly.
Can anybody help me out on this ?
Thanks in advance ,
Dheeraj
