On my machine I have two difference Java (J2EE/jdk) installations.

When I go in Eclipse v3.2.2 to the menu

Help->About Eclipse->ConfigurationDetails

then there are two lines which show that Eclipse uses currently the "wrong" installation:

....
-vm
D:\ORA\v10.1.3.1\OracleAS_1\jdk\bin\javaw.exe
eclipse.ee.install.verify=false
eclipse.product=org.eclipse.sdk.ide
eclipse.startTime=1206457579593
eclipse.vm=D:\ORA\v10.1.3.1\OracleAS_1\jdk\bin\javaw.exe
eclipse.vmargs=-Xms40m
-Xmx256m
....

However I want to use the VM which comes in
D:\java\jdk\bin

Where can I switch (permanently) the VM in Eclipse?

Hello

There are at least 2 ways to define the JVM to be used:

1. Change the environment variable PATH to include the jvm you want
instead of the other one

2. Start eclipse with the option -vm <path to jvm>

For more information about the latter, please refer to the excellent
Eclipse help system:
http://help.eclipse.org/help33/index.jsp?topic=/org.eclipse. platform.doc.isv/reference/misc/runtime-options.html

Hope that helps

Hi Marc. Edit the -vm option in the eclipse.ini file in the top-level
eclipse directory. Here is an Eclipse Wiki article about it:
http://wiki.eclipse.org/Eclipse.ini

Hope this helps. Mark

See this wiki page: http://wiki.eclipse.org/Eclipse.ini

Note that this only controls the JVM that is used to run Eclipse; that
is separate from the JDK used to build your code and the JVM that is
used to run your applications from inside Eclipse (see Preferences >
Java > Installed JREs for that).

Hope this helps,
Eric

Please take care in cross-posting questions and specifying follow-up
groups. This question got several redundant answers because it was
crioss-posted to 2 groups but had the follow-up set to only one. That
means we all saw the question on the platform group and answered without
seeing that others had already answered (answers were forced to only
eclipse.newcomer because of the Followup-To: header).
Hence, wasted time.
