If the error message is:

<Error> <JDBC> <001060> <Cannot startup connection pool "JDSPool"

weblogic.common.ResourceException: Cannot load driver class:

com.borland.datastore.jdbc.DataStoreDriver>

From the WebLogic Console, click Targets, move myserver from Chosen to Available, click

Apply. Check the WebLogic Server configuration from JBuilder. From the JBuilder menubar,

click Tools -> Configure Servers. Click WebLogic Server 7.x from the left panel and check

if you have added the JDataStore driver package jdsserver.jar user in the Class tab in the right

panel.

If you haven’t added them, click Add and add jdsserver.jar from

<JBuilder8_Installed_Dir>\lib directory.

Restart WebLogic Server, click Targets for JDSPool from the WebLogic Server Console,

move myserver from Available to Chosen, and see if the error message is gone.

Error 4: Cannot create data source

Error description

java.lang.NullPointerException at

weblogic.management.console.utils.MBeans.getMBeanClassNameFor(MBeans.

java:1153)

When did this happen

I have created my connection pool called JDSPool successfully using the WebLogic Server

Console. Now trying to create my data source called JDSDataSource, I have entered the

configuration parameters and then tried to assign this JDSatasource to myserver. (To assign to

myserver, I clicked Targets and moved myserver from Available to Chosen.) I see the above

error message in the WebLogic Server Console.

Cause

The pool name entered may not be correct or JDSPool may not be active.
