Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.Install JAVA on a windows box to a directory containing spaces
2.Either set the Windows JAVA_HOME Environment variable or edit the rhq-server.bat file to set the RHQ_SERVER_JAVA_HOME to the above installed JAVA
3.Run rhq-server.bat
Actual results:
Server does not start with Error can't find jvm

Workaround is to use the Windows short name, C:\Progra~1\java\jdk1.6.0_30.

I need to know *exactly* what you set JAVA_HOME to.

I just tried it and the rhq-server.bat worked BUT! only if I did not wrap my env var value in quotes.

Things WORKED when I used this command line to set my JAVA_HOME:

set JAVA_HOME=C:\Program Files\Java\jre7

If I echoed %JAVA_HOME% I saw this:

> echo %JAVA_HOME%
C:\Program Files\Java\jre7

Notice there are NO quotes in the value.

However, things FAILED to work when I did this:

set JAVA_HOME="C:\Program Files\Java\jre7"

> echo %JAVA_HOME%
"C:\Program Files\Java\jre7"

When I ran "rhq-server.bat status", I got this error message:

There is no JVM available.

Turn on debug and see what your script says. So do this:


and then run rhq-server.bat again. You should see what values it wants to use. When using quotes in the JAVA_HOME value, you'll see something like this (which is wrong):

RHQ_SERVER_JAVA_EXE_FILE_PATH: "C:\Program Files\Java\jre7"\bin\java.exe

The quotes appear to be messed up.

So, in short, when you define JAVA_HOME, do NOT wrap the value in quotes.

I'm putting this with a NEEDINFO to the reporter to confirm this work. If it does, we should close this as NOTABUG.

You are correct. In the original case that raised this issue, JAVA_HOME was set as follows:

    set JAVA_HOME="C:\Program Files (x86)\Java\jdk1.6.0_30"

Marking this as NOTABUG.
