Frequently Asked Questions

This section provides solutions to common user questions.

What does this EJB Deployment Message Mean?

When I build the simpserv example, I get the following error:

<date> <Error> <EJB> <EJB Deployment: Tolower has a class which is in the classpath. This class should only be located in the ejb-jar file.> 

This error message can be ignored for this release of the WebLogic Tuxedo Connector. The EJB wants all of the interfaces for an EJB call in the EJB jar file. However, some interfaces for the WebLogic Tuxedo Connector are implemented through the CLASSPATH, and the compiler throws an exception. When the EJB is deployed, the compiler complains that the EJB cannot be redeployed because some of its classes are found in the CLASSPATH.

How do I Start the Connector?

Releases prior to WebLogic Server 7.0 used a WebLogic Server Startup class to start a WebLogic Tuxedo Connector session and a WebLogic Server Shutdown class to end a session. In WebLogic Server 8.1, WebLogic Tuxedo Connector sessions are managed using a WTC Service.

How do I Start the Tuxedo Queuing Bridge?

The Tuxedo Queuing Bridge is started if the Tuxedo Queuing Bridge and Redirections configurations exist in your WTC Service and the WTC Service is assigned to a selected server

How do I Assign a WTC Service to a Server?

The console displays an exception when I try to assign my WTC Service to a server. What should I do?

Make sure you have a valid WTC Service configured. Each WTC Service must have 1 or more Local Tuxedo Access Points configured before it can be assigned to a server. Your server log will display the following:

<Apr 22, 2002 4:21:35 PM EDT> <Error> <WTC> <180101> <At least one local domain has to be defined.>

How do I Resolve Connection Problems?

I'm having trouble getting a connection established between WebLogic Tuxedo Connector and Tuxedo. What should I do?

How do I Migrate from Previous Releases?

You must make some changes in your WebLogic Tuxedo Connector 6.x applications (including WebLogic Tuxedo Connector 1.0) to use them with WebLogic Server 8.1. For more information, see WebLogic Server 8.1 Upgrade Guide.
