Question

I usually do all my java development on linux, using fedora package manager setting up a development environment is easy and fast.

Now I have to start using windows but I never used it for java development and im having a few difficulties having it setup.

So I downloaded and installed thye java 6 JDK (just the standard edition, not the EE) and installed it.

Next I downloaded eclipse classic package, which doesnt have an installer, you just unzip it and run it.

I had to add the java bin directory to the PATH variable, which I did.

But when I start eclipse.exe I get this:

I already made a new environment variable called CLASSPATH and add the d:/java sdk/lib directory to it, but it the same thing. Am I missing something?

Thanks.

UPDATE: so i wrote the path to the java.exe on the eclipse.ini file (linking to jvm.dll didnt work) and now it just opens a console window for a few seconds and then closes (doesnt output anything).

also launching it like: java -jar plugins/org.eclipse.equinox.launcher_1.0.0.v20070208a.jar make the vm work for about 1-2 seconds and then it returns, with no outputs.

UPDATE2: i didnt know it was writting a log file, found it and read it and it said i was using GWT x32 libraries on a x64 VM, so i just downloaded an eclipse x64 version and it worked. i still had to use the .ini trick to say where the JVM is installed.

thanks a lot for the help.

Answer 1

Try referencing the JVM in the eclipse.ini setting file, rather than an environment variable.
See this eclipse.ini

-vm
c:/path/to/your/jdk1.6.0_17/jre/bin/client/jvm.dll

See Finding a VM, Using JNI Invocation or Executing Java on the eclipse wiki for more

Here is a copy of a more general answer (since then deleted) on Eclipse installation:

Having a simple JRE is enough for eclipse to run.
Eclipse will try to launch with the default “java.exe” (the first one referenced by your PATH)

Three things to remember:

• “installing” a JRE or a JDK can be as simple as unzipping or copying it from another computer: there is no special installation steps, and you can have as many different JVM versions (1.4, 5.0, 6.0…) as you want, “installed” (copied) almost anywhere on your disk.
• the JVM you will reference within your Eclipse session is not always the one used for launching Eclipse because:
  • you only need a JRE to launch Eclipse, but once Eclipse launched, you should register a JDK for your projects (especially for Java sources and debugging purposes, also in theory for compilation but Eclipse has its own Java compiler)
    Note: You could register just a JRE within Eclipse because it is enough to run your program, but again a JVM will allow for more operations.
  • Even though the default registered Java in Eclipse is the one used to launch the session, you can want to register an older SDK (including a non-Sun one) in order to run/debug your programs with a JRE similar to the one which will actually be used in production.
• I would recommend to always run Eclipse with the lastest JRE possible (to benefit from the latest hotspot evolutions). You can reference that in your eclipse.ini.
