I recently unstalled jdk 1.3 and installed 1.2.2 for a project (bluemartini 3.2). Yesterday I reinstalled 1.3 with no apparent issues. Are there? Does setting the classpath fix this? Do the installations set any registry values? Are there any other locations that files are written other than c:\jdk1.3 or d:\jdk1.2.2? Thanks-

While I can't answer all your questions, I can tell you about my experience. At one time I had Java 1.1.8, 1.2.2, and 1.3 installed at the same time. I specified which one to use by changing my CLASSPATH and PATH variables to include the specific JDK, and didn't notice any problems.

If you did not uninstall the 1.2.2 version, your PATH environment variable (if you're on a Windows system) still points to the old JDK.
You must set it to the new java.exe
