postgres javax.naming.NamingException

[hanxuerui]

I have made this work on Windows 2000, I have made the directly jdbc call to postgres. I have sucessfully configured a DB2 datasource for jboss, but I can not make the postgres datasource work, it said:

javax.naming.NamingException: Could not dereference object [Root exception is java.lang.NullPointerException] Could not dereference object

Sorry, have not finished my message, the attatch button will post the message, next time I should be careful.

Thanks, please let me know where you think could be a problem in the linux plant form. I have met a problem before, the linux has to have a host name configured, otherwise the jboss will not start up.

What is this time?

Here is another thing I think might mean somthing to somebody.
I invoked
javax.resource.spi.ManagedConnectionFactory startManagedConnectionFactory() through the jms-console on the DS MBean, it has problem like this:

javax.servlet.ServletException: Failed to invoke operation
at org.jboss.jmx.adaptor.html.HtmlAdaptorServlet.invokeOp(HtmlAdaptorServlet.java:190)
at org.jboss.jmx.adaptor.html.HtmlAdaptorServlet.processRequest(HtmlAdaptorServlet.java:78)
at org.jboss.jmx.adaptor.html.HtmlAdaptorServlet.doPost(HtmlAdaptorServlet.java:60)
.....
and:
root cause

javax.management.IntrospectionException: Failed to find PropertyEditor for type: javax.resource.spi.ConnectionManager

You know what, I got it working, I even don't know what happened.

I installed Redhat 9, reinstalled everything, and rewrote the example I used to test the datasource. Then it worked, I don't know what it is, maybe the OS has something with it, or the reinstallation or the rewriting of the testing code.

I am glad it is working now.
