I think perhaps more relevant is which class loader your code is using since it sounds like you are attempting to load the JDBC driver yourself. Your module will get loaded by the code in org.argouml.moduleloader.ModuleLoader2. If you are attempting to use the same classloader that loaded your module, you can see how it is set up there. If you're using the default classloader, that may not be relevant. Have you tried putting the driver jar in the same directory that your module jar is in? That's one place that the classloader is likely to find it since it loaded the module from there. Don't forget that whatever scheme you come up with needs to work not only from the command line, but also when running as a Java WebStart app and, ideally, when running under Eclipse. Each environment has slightly different classloader setups. Tom

If we need to load a driver we specify the driver jar file in the CLASSPATH. This works fine when we run ArgoUML and our module from an Ant build. But when we try to run ArgoUML from the argouml.jar file we can't find the drivers. We tried specifying the driver jar in: java -jar -cp driver.jar argouml.jar And with set CLASSPATH=driver.jar but when our module tries to load the driver class, it can't be found. However, if we specify driver.jar in the Class-Path in the manifest of argouml.jar, it works. This is odd as the class loader should be looking in the jars specified by -cp and CLASSPATH. Is ArgoUML using the default class loader? Thanks, Jeff
