Hi all.
I have Eclipse installed on a network location.
The clients map this location as a drive N:
Clients are Win 7 32bit, domain joined.
Java 6 SE Runtime
Tests are performed as admin.
On PC1, I launch N:\eclipse\eclipse.exe and eclipse starts perfectly.
On PC2, I launch N:\eclipse\eclipse.exe and receive the error:
Error: Could not find Java SE Runtime Environment..
Either of these solutions work to fix PC2:
-vm <path to java>
Modify "PATH" environment variable
However, I am curious to know why this works on PC1 but not PC2. Both PCs:
- have the same base image of Win7 32bit.
- have Java SE 6 installed, JRE and JDK.
- DO NOT have the Java directories in their PATH statement.
- Are not using the -vm switch in the ini file on the N: drive.
So, really I need to know how PC1 is managing to find the java runtime directory. I understand this can be solved with the fixes noted above, but it appears that it shouldn't need fixed in those ways. If it works on the first machine, then there must be some other setting that lets it know where to find Java.
The PCs ARE different as they have been in use for 4 or 5 months and will have different software from one another, so another application may have caused a conflict?
eclipse.ini
-startup
plugins/org.eclipse.equinox.launcher_1.0.201.R35x_v20090715.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.0.200.v20090519
-product
org.eclipse.epp.package.php.product
--launcher.XXMaxPermSize
256M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms40m
-Xmx256m
I think that was the default installation ini.
Any ideas?

What messages do you receive if you run the command java -version from a
command prompt on both PC1 and PC2?

You might want to consider sharing a JDK 6 installation on the network
share and then pointing to it using -vm[1]. That way, you guarantee
which version of Java is being used to run Eclipse at all times, and can
even change it easily if need be.
