Java EE (Java Enterprise Edition) General Discussion

Hello, i need help to next problem:

i download de rowset.jar in JDBC RowSet Implementations 1.0.1 JWSDP 1.4 Co-Bundle link.
So, when I try to use CachedRowSetImpl or JbdcRowSetImpl inside a EJB bean with remote interface, i have a NullPointerException inside RowSet API.

I am using a WID, Websphere Integration Developer 6 with Cloudscape to develop and deploy a EJB application.

The content of my MANIFEST.MF from EJB module is the next:
Manifest-Version: 1.0
Class-Path: CatalogoEJBClient.jar
rowset.jar

So, it�s compiles fine, with no errors, but when i test EJB from UTC - Universal Test Client, gives a NullPointerException.


I tested CachedRowSetImpl or JbdcRowSetImpl in a simple Tomcat application, and it works fine.

Thanks.

The EJB code is simple:

public void testarDB() throws Exception {
ResultSet rs;
Statement stmt;
Connection con;
Context ctx = new InitialContext();
DataSource ds = (DataSource) ctx.lookup("jdbc/WPSDB");
con = ds.getConnection();
stmt = con.createStatement();
rs = stmt.executeQuery("select * from teste");
CachedRowSet j = new CachedRowSetImpl();
j.populate(rs);
j.close();
rs.close();
stmt.close();
con.close();
rs = null;
stmt = null;
con = null;

}


Exception:
