Issue with installing older version of jdk in X.P

    Hi Guys,

    I am having a problem where I need to compile a java project using jdk1.4. I understand that 1.4 is at E.O.L but due to an application server I am deploying to it needs to be compiled in 1.4.

    I have download a version of jdk 1.4 and added it to my path but when I run the command java -version it has not changed but the old jdk 1.6 is the current version!!

    I restarted my machine a number of times but no joy. The version I was using before I started to make changes was 1.6 update 5, I downloaded jdk 1.6 update 7 (running out ideas!!) and when I added it to my path and ran the command java -version the new version of jdk was picked up. I then tired to rollback to my jdk 1.6 update 5 by changing the path but it did not rollback to jdk 1.6 update 5 but now jdk 1.6 update 7 was the current version.

    I now belive that somewhere the newest version of the jdk is being stored (possible reg keg??). Has anyone advice on what the best approach would be clear out all older version's? Or has anyonwe come across an issue like this before and how did they resolve the issue?

    Mnay thanks in advance

    Your problem is that java.exe is in your path.. more than likely in the system32 directory. Use the full path to jdk1.4 when running your app.. i.e. c:\jdk1.4\bin\java abc.class

    No it is nothing to do with a reg key.

    Are you sure you added the bin folder of jdk1.4 to your path. If you are on windows within your shell you can use the command like
    set PATH=c:\jdk1.4\bin;%PATH%

    On linux
    export PATH=/usr/bin/java1.4/bin;$PATH

    You will also more than likely need to set the JAVA_HOME env variable for your server to work.

    **Sorry, didn't notice the XP bit until now.**
