Getting Hibernate 3.1.12 to work with JSDK 1.4

I had some trouble to get the latest Hibernate release to work. I have to use JSDK 1.4 but I got the following error message when I started my application:

HTTP Status 500 -

I have f ound in the Hibernate forums that I need to recompile with JSDK 1.4, but that didn’t work imediatelly.

I had to do the following change to the build.cmd file in the Hibernate directory:

from:

java -cp “lib/ant-launcher-1.6.5.jar” org.apache.tools.ant.launch.Launcher -lib lib %1 %2 %3 %4 %5

to:

C:\Programme\Java\j2sdk1.4.2_09\jre\bin\java -cp “lib/ant-launcher-1.6.5.jar;C:\Programme\Java\j2sdk1.4.2_09\lib\tools.jar;C:\Programme\Java\j2sdk1.4.2_09\jre\lib\rt.jar” org.apache.tools.ant.launch.Launcher -lib lib %1 %2 %3 %4 %5

In the new version I use the java.exe from JSDK 1.4 and I also had to add rt.jar and tools.jar to the classpath.
After that I could compile without problems.
