Hello –
I am trying to debug a webapp of mine using eclipse 3.0 and the sysdeo
plugin. Starting and stopping both work fine, but when i try to go to
the root page of the webapp i get the below error. I have eclipse
setup to use the jdk jvm.When I start tomcat via the command line, my webapp works fine and I can connect via remote dbg, but I cannot set break pts.
Any help you could offer would be greatly appreciated.
Scott

org.apache.jsp.index_jsp._jspService(index_jsp.java:135)It looks like you are deploying against a different version of jsp-api.jar than what you are developing against. I would highly suggest that you never include your server libs (servlet-api.jar, jsp-api.jar, etc.) in your project but instead link out externally to the JAR or create a User Library for it.
Hrm, I searched my system and the only jsp-api.jar available on my system was the one located in Tomcat\common\lib
Is there some other way I could be developing against or deploying against that jar?
I noticed in your project output you have servlet-api.jar in your project (compile-lib), my comments apply to that as well, try and remove it and link externally to the JAR.
This is hard for me to trouble shoot as I don’t use Sysdeo.
Maybe I can ask a different question. When I start tomcat via the command line (tomcat jpda start), my webapp works fine. If I try to debug it in eclipse, I am able to connect to the process, but I cannot set break points (it complains about not having enough info to set the break point). I could swear that the following was the right setting needed to put debug info into the java files:
<javac debug=”on” destdir=”webroot/WEB-INF/classes” srcdir=”src” source=”1.4″>
blah, blah, blah
</javac>
Am I missing something? I am using the JDK 1.5.01
That looks fine to me… can you not build the webapp with MyEclipse and deploy it? Try it that way and see if it works.
Riyad,
Thanks so much for the help, your input caused me to double check my build.xml. The problem was that my debug build depended upon my release build (doh!) and thus the war really, truely had no debug info. I can now set break points, etc.
Thanks again for your help,
Scott
