This has nothing to do with Struts. This is a web container issue. Read your web container docs. In short, there are two basic ways to do this: Write a single servlet that nudges the web container to compile all of your JSP pages. I believe several web containers already provide a feature to do this, including Tomcat. Alternatively, all web containers have a command-line class, often called something like "JspC", which will generate the servlet source code from the JSP pages. After you generate the servlet source code, you have to use the java compiler to compile them, and you'll also most likely have to insert "<servlet>" and "<servlet-mapping>" elements in your "web.xml" file for each one of those generated servlets. The tradeoff between these two strategies is that the first one is often much easier (if the web container provides the servlet), but the second one provides for a more robust build process, as you'll see more possible errors in your build, as opposed to after it's deployed. On the other hand, the second strategy causes you to deploy a war file that is web-container specific. The JspC class in some containers also compile the generated servlet at the same time. Some of these web containers may either generate the "web.xml" fragment that needs to be inserted, or modify the "web.xml" directly with the updated mappings. Look for features like these in your web container docs and experiment. -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
