Re: workaround for weblogic5.1 cast exception
I forgot to mention another step that may be needed to make 0.5 struts-example work with weblogic5.1: If you call a *.jsp page before the ActionServlet init() method ever gets called you will get the following exception: javax.servlet.jsp.JspException: Missing resources attribute org.apache.struts.action.MESSAGE at org.apache.struts.taglib.MessageTag.doStartTag (MessageTag.java:360) at jsp_servlet._index._jspService(_index.java:82) e.g. If you use the url "http://.../struts_example/" you're web.xml has welcome-file-list welcome-fileindex.jsp/welcome-file /welcome-file-list This bypasses the ActionServlet calls the *.jsp directly. But if ActionServlet.init() method has never been called then it hasn't had a chance to insert the ResourceBundle into servletContext.Now when the jsp calls the MessageTag custom tag handler, MessageTag tries to get the ResourceBundle from the servletContext but it doesn't find it cause its not there yet.To fix this just make sure the ActionServlet gets called at least once.Either when weblogic startsup or manually e.g. if you've mapped the ActionServlet to be called for a *.do file just use a url like "http://../struts_example/x.do". The example should now work correctly assuming you have done the other two steps I mentioned before: 1) unjar the war file cause weblogic5.1 can't handle resource bundles in *.war. 2) add the jps-precompile section to web.xml param-nameweblogic.jsp.precompile/param-name param-valuetrue/param-value /context-param This leads to a question I have: How do you prevent people from bypassing your ActionServlet and going directly to a *.jsp without putting extra logic in the jsp. E.g. I may not want people to bookmark a jsp because I want security/authentication/session management to be done in my central servlet. It seems to me that I have to insert logic into ALL my JSPs (e.g. by calling a bean) to make sure that a person has logged in or has a valid session. But I do not want to put this logic in a jsp I want to handle it from a central servlet. Is there a way to do this or am I stuck putting the logic in each jsp ? --- renzo estrella [EMAIL PROTECTED] wrote: I made the struts-example struts-documentation demo apps work by doing the following 2 steps: 1.

Re: Weblogic 5.1 and Struts 1.0, Classpath question
This may be caused by the cast exception problem: MessageTag code first gets tries to get the MessageResources from servletContext.getAttribute() It then cast the object returned to MessageResources this failure may be leading to your problem so I would suggest you try including the following sectoin into web.xml: context-param param-nameweblogic.jsp.precompile/param-name param-valuetrue/param-value /context-param --- Harit Nanavati [EMAIL PROTECTED] wrote: I have been trying the same thing.

Re: Weblogic 5.1 and Struts 1.0, Classpath question
I was using the struts 0.5 examples I did not unjar the main struts.jar file, I left that in the lib directory. Instead I unjarred the struts-example.war file modified the web.xml for the struts-example demo. Weblogic5.1 doesn't seem able to read ResourceBundles from a *.war file. I have not tried the 1.0 examples, if you are using those perhaps what I did those not apply. --- Harit Nanavati [EMAIL PROTECTED] wrote: Just did that .. sturts.jar extracted. directory in WL classpath war file extrected. deleted starts.jar from lib directory added the addtional precomple lines in web.xml All the jsp compiles without problem.
