class file has wrong version 50.0, should be 49.0

edward wang
Hi Folks,

I am workign on an ofbiz project. the ofbiz version has been used for almost
1 year.
we use j2sdk1.5.0_01 to compile and run.

but hen i use ant to compile.
I got this exception:

 [javac]
C:\sgcsworkspace\SGCS\framework\catalina\src\org\ofbiz\catalina\container\SslAcceleratorValve.java:26:
cannot access javax.servlet.ServletException
    [javac] bad class file:
C:\sgcsworkspace\SGCS\framework\catalina\lib\servlet-api.jar(javax/servlet/ServletException.class)
    [javac] class file has wrong version 50.0, should be 49.0
    [javac] Please remove or make sure it appears in the correct
subdirectory of the classpath.
    [javac] import javax.servlet.ServletException;


my environment is  1.5.0_01. JVAHOME=C:\JavaAPI\j2sdk1.5.0_01

javac and java version are 1.5.0_01.
I can compile it at another machine which has the same setup.
servlet-api.jar is from the same repository.

I don't know reason why my computer has this issue.

Please help

no, i didn't change. i only saw they changed tomcat jar file to 5.5.28
But it can compile in Eclipse.
Do i need to change jre env?
50.0=1.6 49.0=1.5
There is no 1.6 jdk in my computer.

Help yourself: from the OFBiz main page use the wiki search, type "1.5", or jdk, or...
