Is it ok to run 1.5 with 1.4 on the hard drive?
Hi. If anybody has a minute, I think I remember having problems with havng two versions of the sdk on the hard drive. I was thinking of uninstalling 1.4.2 before I install 1.5 but I do not see an executable uninstall file. Is it ok to install 1.5 under a different directory while leaving 1.4.2 on the machine and modify the autoexec file to point to the 1.5 directory. I'd rather just clean 1.4.2 out but like I said, I can't find an uninstall and I kinda don't want to just move the 1.4.2 directory to the recycle bin withut knowing where there are lingering files that might mess with 1.5. Thank you very much for reading this.

Having both 1.4 and 1.5 works fine for me, in Unix and Windows at least. "java -version" helps when unsure which one is in PATH.If you do want to uninstall a JDK in Windows, go to start -> settings -> control panel -> add/remove programs.
To reinforce the caution - The SDK doesn't create Registry entries and so its directories can be moved or deleted with no harm. BUT the JRE does create Registry entries,and if you mess with it you're creating problems.
Don't do this kind of stuff unless you really know what you're doing...
Use the uninstaller.
I am happily using a plethora of JDK versions on Linux and Windows and Solaris. I either readjust PATH or simply use wrapper scripts that directly launch the appropriate java, javac, javap program. Varietas delectat.
Oh man, can soembdoy help me? I installed 1.5 and it hosed up my Java Web Start.
Then when I went to reinstall Web Start, it told me it couldn't detect a JVM on my machine and prompted me to install 1.3.
Can anybody point me in the right direction to get Web Start running with SDK 1.5? Thank you...
Hi. I think I have web start running ok...but now I can't seem to get asnything to compile with the 1.5 compiler. I changed autoexec.bat to point to c:\jdk1.5.0\bin and I keep getting bad command or file name when I run javac filename.java. If I change it back to what I havd previously in autoexec.bat, which was c:\jdk1.4\bin, the 1.4 compiler works as before. Does anybody know if I'm missing something here? Thank you.
