This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
I have two different web applications that have different JSPs. However, they both use a common set of java classes that are in a package called vss. I am having trouble trying to get the JSP to find the vss package unless it is installed under my web application in WEB-INF/classes. I would like to install the package in a directory that is entirely separate from the Tomcat installation. I did this and then placed the full path name for the vss.jar in my classpath environment variable. I re-started Tomcat. The application is a bit complicated because it is VXML instead of HTML, in other words it is a voice application, not a web browser application. In any case, suffice it to say that it didn't work with my new configuration. Can someone tell me if there are rules against executing Java classes that are not in the WEB-INF directory structure? Or did I just do something wrong? It is entirely possible because there are so many weird bits and pieces to this application. For now, I am maintaining two copies of the source code and the compiled classes -- one under each web application's WEB-INF directory. Thank you!
Most servlet containers will take no heed of the system classpath. To share a library of classes across multiple web applications, each container will provide a common area. In Tomcat, for example, you would jar up your classes and place the jar file in $CATALINA_HOME/shared/lib.
Thank you. I think that I will keep the source code under one app and place the vss.jar in my Tomcat common/lib directory. I forgot that Tomcat ignores the system classpath. As usual I am trying to do too many things at one time so it is hard to see which one of them is causing me problems.
