JDBC resource gets configured from command line where all DS connection attributes are given correctly.I get a message saying " JDBC Resource Configuration Completed " .I open admin console of WAS(7.0beta) & try to test the connection for the newly created datasource.

I get following error:

The test connection operation failed for data source TradeDataSource on server nodeagent at node was7node1 with the following exception: java.sql.SQLException: [jcc][t4][10205][11234][3.50.152] Null userid is not supported. ERRORCODE=-4461, SQLSTATE=42815DSRA0010E: SQL State = 42815, Error Code = -4,461.

Here's what i get to configure on command line while creating this datasource
