Problem(Abstract)
Connection to AS/400® IBM® DB2® Datasource fails:

[4/7/05 13:59:15:550 EDT] 10efb8a DataSourceCon E DSRA8040I: Failed to
connect to the DataSource. Encountered :
java.lang.InternalError: Can't connect to X11 window server

Cause
The AS/400 JDBC driver has properties that allow for a user to be prompted. This fails if the username has not been passed to the getConnection() method or if the data source configuration has not specified a J2C authentication alias.
 
Resolving the problem
Ensure that the username is passed on the getConnection() call.

If the application is using Container-managed Authentication or Component-managed Authentication, then confirm that the J2C authentication alias is specified correctly for the data source defined. This is done through the administrative console.

If the application is not using a J2C authentication alias defined on the data source, ensure that the username and password are being passed on the getConnection() call.

To find the Javacdocs for the AS/400 JDBC driver, see the Javadoc available from the IBM® iSeries® Information Center Version 5 Release 3 (V5R3).

The specific JDBC properties that can be set can be found here: IBM Toolbox for Java™ JDBC properties.
