RE: Please Help: Struts issues in Weblogic5.1.0 (sp5+)
In reference to your question, it looks like WLS 6.0 has changed it's classloader hierarchy to be more J2EE compliant. As a result the servlet's and the jsp's have the same classloader identified by object.class.getClassLoader(). With respect to classloaders, all seems well with WLS 6.0. However I just got it to work last night. As for WLS 5.1 spX the only hope I've found is a hack provided by Erik Pearson at the following URL. I have not attempted his suggestion. http://archive.covalent.net/jakarta/struts-user/2000/10/0009.xml -ta -Original Message- From: Magnus Petersson [mailto:[EMAIL PROTECTED]] Sent: Friday, January 19, 2001 1:16 AM To: [EMAIL PROTECTED] Subject:Ang: Please Help: Struts issues in Weblogic5.1.0 (sp5+) I have encountered exactly the same problems and solved them the same way as described by Eric Pearson. This solution seems to work well as long as we run on WLS 5.1 sp6. There is another issue though. In WLS 5.1 sp8 the load-on-startup tag in the deployment descriptor has been fixed and works as it should. This sounds nice at first but the problem is that this causes the servlets to be loaded before the jsps and therefor loaded by the wrong classloader. In other words, Struts does not work with sp 6. If anyone has a solution to this problem I would really appreciate to hear about it. I would also like to hear about experience running Struts on WLS 6.0. Has anyone had any problems?

RE: Please Help: Struts issues in Weblogic5.1.0 (sp5+)
I took a look and saw no struts.jar file outside of a lib or _deployment_dir of a web app. The start.cmd file of weblogic doesn't point to any dir that contains a struts.jar file and the Weblogic.properties file only contains the one web app config. Is the point that the files being loaded by a classloader higher up the hierarchy than the webapp classloader in Weblogic? What do you think?
