Version issue while deploying

I have a new install of Sun App server. When I try to deploy a web module I am getting the following error. I have JDK version 1.5 and JRE version 1.5. I checked under HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft and in Control pannel, Add remove programms.

Unable to load servlet specified in the module.
Please consult online help for assistance.
java.lang.UnsupportedClassVersionError: TestServlet (Unsupported major.minor version 49.0)

Any help appreciated.
Thanks.

Check that your PATH contains the right version of your JRE.
It may be pointing to an older version (it often happens when Oracle is installed)

I got this error when I was using Tomcat 5.0.28 and deployed classes compiled with JDK1.5 , Then recompiled with 1.4.X and this error did not show up.

I guess same thing may be happening in your case, compile your classes with jdk1.4 it may solve your problem.

Use Tomcat 5.5.x. This version is for JRE 5

Hey

I too got this problem when I tried to use the classes compiled with jre1.5 in jre1.4.

I tried both compilation and running using jdk1.4

Cheers,
Su Yeu.

I tried compiling using C:\Sun\Creator\java\bin\javac.exe and it worked. So I reinstalled sun app server again and it works now.
Thanks for everybody who stepped in.
