Hi,

I can’t view the values of local variables in jsp when debugging on Resin 3.0, but I can on Tomcat
5.x. Does anyone what’s going on? Thanks in advance.

Joey,
What version of Eclipse/MyEclipse? What version of JDK are you running MyEclipse with and which version are you running Resin/Tomcat with? What version of Resin? What version of Tomcat? Resin Pro or Resin normal?

Joey,

Resin, depending on version, has proven problematic for debugging over time due to sketchy JSR-045 support. A big thread on that is here:http://www.myeclipseide.com/PNphpBB2+file-viewtopic-t-5033-highlight-resin+ken.html

What might be happening is that your breakpoint is being hit, but it isn’t stopping exactly where indicated due to optimizations in the generated code used by Resin, as detailed in the above thread.

Or, it could be something else so answering Riyad’s questions would be the first steps toward finding out what’s up.

Hi,

The versions I used are as follows:

jdk1.5.0_02
eclipse 3.1.1
MyEclipse 4.0.1
Resin-3.0.12 normal
Tomcat 5.5.9

Thanks again for your help.

Joey,
I think Scott nailed it, if you start stepping through the code, do you see the variable in the debug view popup eventually or does it always not show them?

Hi,

The program is stoped in the breakpoint and I can step through, but the values of the local variables just didn’t come out, not even the names. If it is because the optimizations by Resin, can I turn it off. Thanks for your help

Joey,
It’s possible this could be the issue, you will need to double check the resin docs. I know that other servers like Weblogic have similar “debug” settings you need to set in the configuration so they compile the JSP pages with debugging information included.
