limitation on hbj control in jsp ?

[Former Member]

Has anyone experienced this wierd situation before.

I have a few hbj controls on my java iview. I am implementing a purchase order transaction (ME23N) as a java iview. Surely there are going to be a lot of hbj controls. Now I have reached a stage where it seems I cannot add any more. I get this error message. I have no idea why this is happening.

Error Message :

Caused by: java.lang.VerifyError: (class: pagelet/_sapportalsjsp_Form, method: doContent signature: (Lcom/sapportals/portal/prt/component/IPortalComponentRequest;Lcom/sapportals/portal/prt/component/IPortalComponentResponse;)V) Illegal target of jump or branch

Thanks for your help in advance

This is actually a problem not with the jsp size but with the service method in the generated servlet. This is a limit stated in the JVM specs here http://java.sun.com/docs/books/vmspec/2nd-edition/html/ClassFile.doc.html#88659 for all methods. I'm not sure what JVM version this document is for but I think it still holds true. This will be a problem until the jspc's become a little smarter about segmenting the service method. One workaround is to segment your jsp into multiple jsp's and use the <jsp:include> tag to combine them. This also promotes reuse if done well.

I had written a blog about this you can find it over here

Also look at the last comment in the blog.

Hi

This is because of the limitation of JSP pages to only 64k. Therefore, when you use a lot of HTMLb elements in your pages, the Java compiler cannot compile the page. Therefore, I would recommend using the Java API's of the GUI elements to perform the rendering instead of using the JSP
