Re: 500 lines of jsp is 10k lines of java
I experienced the same problem with Weblogic 5.1 sp8. To fix it, I increased the initial heap and maximum heap size arguments for the Java VM in the Weblogic server startup BAT file to: -ms256m -mx256m This may be overkill for your situation, but it should work.

Surely I'm not the first to deal with this (and it's a real show-stopper). Anybody know a way to deal with this (other that hand editing the source-code)? This isn't a struts problem per-se but it's being interpreted that way by the powers that be where I work. Not good!

Does this include images? If I have images with text on them in English can I make images with text in French as well? Do I name the image files differently or do I have to include the paths to the images in the property files? Has anyone done this? What's the best approach?

RE: Illegal target of jump or branch Error
Thank you for your explanations. As a result I changed the -ms and -mx options for the Java VM to request 256 MB of heap memory...and it worked.

I also believe it has to do with the method that is generated when the jsp is compiled being too large. When I took the class that was generated by Tomcat for the page and compile it on the command line, I get the 64kb limit exception. I do not know why the "Illegal target of jump or branch" error gets thrown in Tomcat as opposed to the 64kb limit exception.

I had similar problems using Jasper. I managed to refactor the page so that the number of actual tags was reduced (put a loop in it, so the tags were called multiple times). Using scriptlets (!) can also help significantly... or if you can afford the flush, use jsp:include (roll on JSP 1.2). [EMAIL PROTECTED] on 07/02/2001 06:59:08 Please respond to [EMAIL PROTECTED] To: [EMAIL PROTECTED] cc:(bcc: Ken X Horn) Subject: Re: "Illegal target of jump or branch" Error Interesting. A colleague of mine started seeing exactly the same problem today, but with Resin instead of WebLogic. I had never seen it before. It seems, on the face of it, to have something to do with the complexity of the page. The page we were having problems with has a boatload of custom tags on it (some Struts, others our own). When we commented out a sizeable number of those tags, it started working again. Which particular chunk of tags we removed did not make a difference, which is what led me to believe it was related to page complexity. However, that's as far as I've got. I'd be very interested in hearing the "real" reason behind this error, as well as what we might be able to do about it. -- Martin Cooper Tumbleweed Communications - Original Message - From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Tuesday, February 06, 2001 8:00 AM Subject: HELP: "Illegal target of jump or branch" Error I receive the following error when accessing my JSP in WebLogic 5.1 (sp8): Tue Feb 06 10:56:07 EST 2001:E WebAppServletContext-smartforms Servlet failed with Exception java.lang.VerifyError: (class: jsp_servlet/_test, method: _jspService signature: (Ljavax/servlet/htt p/HttpServletRequest;Ljavax/servlet/http/HttpServletResponse;)V) Illegal target of jump or branch at java.lang.Class.newInstance0(Native Method) at java.lang.Class.newInstance(Class.java, Compiled Code) at weblogic.servlet.internal.ServletStubImpl.createServlet(ServletStubImpl.java :431) at weblogic.servlet.internal.ServletStubImpl.createInstances(ServletStubImpl.ja va, Compiled Code) at

Tag Library Definition Inheritence
Just as functionality can be inherited as you subclass the tag handlers, is it also possible to inherit the corresponding tag interface definitions in the library file? The TLD files are growing unnecessarily large. Thanks.
