FAQs: Code Examples

• Where are the examples located?
• Why won't the examples work?
• Are the build.cmd and the build.sh scripts still being used?
• How do I use ANT?
• Why do I have trouble targeting a PointBase connection pool to a remote server?
• Why do I get an error if I attempt to start the MedRec Server on a system that uses a proxy to connect to the Internet?

Q. Where are the examples located?

A. Examples, if installed, are located in the BEA_HOME\samples\server\examples\src\examples directory, where BEA_HOME refers to the main WebLogic Platform directory. To invoke a Web page that describes the examples, see the Start menu on Windows.

Q. Why won't the examples work?

A. Each example comes with detailed instructions for building the example class files, configuring the server, and running the example. Make sure that you have completed each of the example instructions.

Usually problems with examples are related to your environment. Here are some troubleshooting hints:

1. If you are using a database, make sure you have run the utility utils.dbping to verify that your JDBC driver is correctly installed and configured.
2. Run the setEnv script to make sure your CLASSPATH is correctly set in the shell or DOS window in which you are running the examples.
3. Check the instructions for the examples to make sure you have changed any user-specific variables in the code before compiling.
4. Verify that you are compiling with the -d option to direct the class files into the proper directory, as defined in the example instructions.

If the example is an applet, check the CODE and CODEBASE, and make sure WebLogic Server is running.

For more information, see the WebLogic Server Examples Guide located at BEA_HOME\samples\server\examples\src\examples\examples.html, where BEA_HOME refers to the main WebLogic Platform directory.

Q. Are the build.cmd and the build.sh scripts still being used?

A. No. They have been replaced by ANT.

Q. How do I use ANT?

A. Set up the Examples domain environment by running setExamplesEnv.cmd in Windows or setExamplesEnv.sh in UNIX. Go into your examples directory and type ANT to build the build.xml file. If you want to build your own build script, you can pass in the name of the build script by typing ANT -f myBuild.xml where myBuild is the name of your build script. For more information, see the Apache website.

Q. Why do I have trouble targeting a PointBase connection pool to a remote server?

A. Open the commEnv.cmd or .sh file in WL_HOME\common\bin and edit the POINTBASE_CLASSPATH entry by removing the bolded section of the entry shown below:

set POINTBASE_CLASSPATH=%POINTBASE_HOME%\lib\pbserver44.jar;%POINTBASE_HOME%\lib\pbclient44.jar

Q. Why do I get an error if I attempt to start the MedRec Server on a system that uses a proxy to connect to the Internet?

A. The MedRec Server uses the Struts framework and its attempts to access jakarta.apache.org on startup result in error messages. The server starts up successfully, but with error messages. Adding the following options to MedRec Server's start script resolves the issue:

  -Dhttp.proxyHost=<Your Proxy Host> 

  -Dhttp.proxyPort=<Proxy Port>
