Hi,

I have downloaded eclpse 3.1 which requires jvm 1.4.* for running .. now
although i have jre1.4.2 eclipse refuses to start, sayin that java 1.3 is
reqd and it has detected jvm 1.3 ... i suppose that eclipse is not able to
select the jvm, but in that case i tried running eclipse with the -vm
argument and it still doesnt run, stating specifically that no jvm has
been found, how do i fix this ..

You are correct that you should always use the -vm argument to
explicitly tell Eclipse what JVM to use.
What is the exact command-line you are trying? Most likely there is some
small mistake in it that is keeping you from success.

Hope this helps,
Eric

The full command that i used to run is with the vm argument :
D:\> eclipse.exe -vm "C:\Program Files\Java\j2re1.4.2_04\bin\client\jvm.dll"

Try this

D:\> eclipse.exe -vm "C:\Program Files\Java\j2re1.4.2_04\bin"

This should work. The -vm path should point to the place where java.exe or
javaw.exe is placed.

It gave an error ... " D:\eclipse\eclipse.exe not a win32 application "

Can you please mention some of ur folder details.

1. In which folder eclipse is installed?
2. In which folder java is installed?
3. What is the exact text which you have typed to open eclipse using the
-vm runtime option?

You don't specify the DLL, you specify the JVM executable. For example,
"C:\Program Files\Java\j2re1.4.2_04\bin\javaw.exe"

Note that it is recommended you use a JDK, not a JRE, for running Eclipse.

Hope this helps,
Eric

A JRE is ok to run, but I would recommend a JDK to compile against.

i went to the folder where eclipse is installed, 'D:\eclipse'>
The exact string that i typed was:
"eclipse -vm "C:\Program Files\Java\j2re1.4.2_04\bin"

the path should contain the executable as well (not only the directory),
i.e., -vm "C:\Program Files\Java\j2re1.4.2_04\bin\java.exe"

Is there a chance you downloaded the Windows x86_64 or Windows ia64
install rather than the Windows install? It sounds as if you're not even
getting to the point where the JVM would matter.

It did fix the problem but is there any way i can configure it to run with
the 1.4 vm by default, i mean is there a way where by i wont have to issue
a cmd line arg always..

Yes, you have two options:
A) create a Windows shortcut or "batch" file that contains the full
command-line, then you can double-click that shortcut to launch Eclipse.

B) In the same directory as eclipse.exe there should be a file
eclipse.ini - in that file you can specify startup parameters. Just be
careful as the format of the file is very particular and it will fail if
you get it wrong (line breaks are important). Below is a sample of my
eclipse.ini file which you can adapt for your own set-up.

Hope this helps,
Eric

--- Begin eclipse.ini ---

-vm
D:\Java\JDK\1.5.0\bin\javaw.exe
-vmargs
-Xms40m
-Xmx512m
-XX:MaxPermSize=128m
