Specifying javac in WLS 5.1 for deployed web appliations (.war)

Question

          I am using WLS 5.1, sp10. I have created a J2EE web application (e.g.
          .war file), which I have deployed in exploded directory format. My
          .html pages and servlets are working fine. My .jsp pages are not
          compiling however. In my web.xml, I have only registered the servlets,
          not the jsp pages. I have also made no JSP settings in the web.xml
          file.
          This is the error I'm getting:

          I think the problem is that the java compiler (javac.exe) is not
          correct. In my weblogic.properties file, I changed the compile command
          to use the jdk I installed, so the path is d:/jdk1.2.2/bin/javac.exe.
          However, it did not seem like the web application looked at the
          weblogic.properties setting.
          I solved the problem by putting d:/jdk1.2.2/bin into the path system
          variable on my WinNT machine. But I don't like that solution. I also
          don't want to specify the javac location in the web.xml -- I want our
          customers to determine that, since they might be using a wide range of
          jdks.
          Is there a weblogic-specific solution out there?
          TIA,
          Steve

Answer 1

I should mention that regular jsps, located in the public_html
          directory, compiled fine, without me having to put javac.exe in the PATH
          system variable.
