Changing current version of Java within Windows

I’m working in a Windows XP environment and have recently installed java 1.6 because it was required by an application. However I don’t want this to be the default version of java to be used. How do I set it so that the command java -version will return 1.5.x

I would take a look at path environment variable. You can examine it in command line with: echo %PATH% . These are default folders where binaries are looked for. If you find a path to JAVA you could adjust it easily in System Preferences.

Change your PATH variable so that it has the location of the jdk5/bin directory:

  1. Start -> Control Panel -> System -> Advanced
  2. Click on Environment Variables, under System Variables, find PATH, and click on it.
  3. In the Edit windows, modify PATH by adding the location of your jdk5/bin directory to the beginning. If you do not have the item PATH, you may select to add a new variable and add PATH as the name and the location of the directory as the value.
  4. Close the window.
  5. Reopen Command prompt window, and run java -version

That’s because when you install Java, the bins are put into C:\WINDOWS\system32, which is part of your PATH. You should add the jre/bin directory to the beginning of the PATH.

If you have multiple JREs installed, the only way to achieve this is by changing the registry entry. Especially because there are tools which read the JRE info from registry and not the class path.

set JAVA_HOME=C:\jdk1.6.0u24 set PATH=%JAVA_HOME%\bin;%PATH%

That will temporarily set up the environment in the command shell. Maven, Ant, etc. will pick up on your new version of Java without having to go to the Control Panel repeatedly.

Tools like Eclipse should be able to select which JDK to use in their own configuration tools for use within their environments.

Java 8 creates three shortcuts on \ProgramData\Oracle\Java\javapath that point to the latest Java8 java.exe, javaw.exe and javaws.exe and then puts \ProgramData\Oracle\Java\javapath at the front of the PATH so that no matter what you do to the JAVA_PATH environment variable, you still get the latest Java 8.

You can get around this by

1) renaming \ProgramData\Oracle\Java\javapath to something else (\ProgramData\Oracle\Java\javapath8 for example)

2) creating a new javapath folder under Java and

3) creating the shortcuts that you need.

Just restore the javapath when you are done with the old versions and you get Java 8 back.

Short, but to the point, very good answer, this one explains more specifically how to generate multiple versions of javapath folders, using symbolic links, so you could switch with no time between versions, and the registry stuff that is missing here, screenshots and trick to avoid reboot after changes too. see stackoverflow.com/questions/27996603.

There are two ways to fix this:

1) Change the PATH (as someone has already mentioned) The important thing with this solution is to set JAVA_HOME before the windows paths. This is because under the windows folder, there is a java.exe that redirects to the last installed jre.

2) Regedit. The key HKEY_LOCAL_MACHINE->SOFTWARE->JAVASOFT->Java Runtime Environment contains the last installed version that the java.exe in the windows folder redirects to. If you change this to a previously installed version, everything should be peachy. (At least, I think this is the right registry key)

How to run JAR file with different version of java

I downloaded jdk and jre1.5.0_16 and compile my project(this one is quite old so it had some error with the newest version) in Eclipse fine. But my default JDK is still 1.6

ngu@MyUbuntu:~/workspace/ims-communicator$ java -version java version "1.6.0_20" OpenJDK Runtime Environment (IcedTea6 1.9.9) (6b20-1.9.9-0ubuntu1~10.10.2) OpenJDK Server VM (build 19.0-b09, mixed mode)

Re: How to run JAR file with different version of java

In a terminal, navigate to the directory containing the java 1.5 executable

and run your command from there.

Alternatively you can set 1.5 as your default Java installation by running

sudo update-alternatives --config java

ngu@MyUbuntu:/usr/lib/jvm/jdk1.5.0_16/bin$ ./java -jar /home/ngu/workspace/ims-communicator/ims-communicator.jar
Exception in thread "main" java.lang.NoClassDefFoundError: javax/media/NoProcessorException at net.java.sip.communicator.SipCommunicator.(SipCommunicator.java:126) at net.java.sip.communicator.SipCommunicator.main(SipCommunicator.java:423)

I think it relates to JMF. Do you have any idea how to fix this? I have already done a lot of search but nothing seems helpfull.

Do you know how to change CLASSPATH and LIBRARY_PATH and other necessary stuffs for JMF. I’ve downloaded JMF from SUN website

Re: How to run JAR file with different version of java

I’m guessing you did not install the Sun JDK 1.5 via Synaptic Package Manager or apt-get.. so Ubuntu will not know about it.

Here you will find instructions on how to add different Java version to Ubuntu so that you can switch to them via the alternative command:

Re: How to run JAR file with different version of java

Azdour is correct, you cannot simply copy jdk1.5.0_16 into usr/lib/jvm, that’s not the way to do it. Read the help.ubuntu.com link I gave in my initial post for the way to install Java correctly. Once you have it correctly installed, you can follow either of the two options I gave.
