There is probably a simple solution the problem I’m having but apparently I’m not smart enough to figure it out. I am trying to install EnterpriseWorkbenchInstaller_030700RC2.bin on my RedHat 9.0 box. I have j2sdk1.4.2_02 installed in /usr//java. JAVA_HOME is set to /usr/java/j2sdk1.4.2_02 and the java excutable is in my path. Sooooo..

When I run the installer I get

[wroberts@wroberts-desk dl]$ ./EnterpriseWorkbenchInstaller_030700RC2.bin
Preparing to install…
Extracting the installation resources from the installer archive…
Configuring the installer for this system’s environment…

I’ve modified my classpath to explicitly include all the jar files in lib but I continue to get this exception.

Any help would be greatly appreciated.

Warren,
installsheild likes to first find then order all the VMs it finds on your machine, so what is probably happening is that its finding an old VM (or maybe kaffee or alternative VM) and actually trying to run with that instead. You can force it to use a specific VM by useing the following command before execing it:

export LAX_VM=/usr/java/j2sdk1.4.2_02/bin/java

I’m assuming you are using a bash shell. Also if that doesn’t work try different versionso f that path… I don’t exactly know if it needs the absolute path to the bin to run (like I have) or just the path to the bin dir, or just the home path…

[warren@roberts.name]

😥

I tried all different combinations of exporting LAX_VM

/usr/java/j2sdk1.4.2_02/
/usr/java/j2sdk1.4.2_02/bin
/usr/java/j2sdk1.4.2_02/bin/java

I get the same error

[Riyad Kalla]

Ok I’m almost positive that this is a problem of the installer not using your JDK installed, if you look back at your original report, you see the line:

Exception in thread "main" java.lang.InternalError: Unexpected exception while defining class ZeroGt: java.lang.ClassNotFoundException: javax.swing.JDialog 
at 0x40268e17: java.lang.Throwable.Throwable(java.lang.String) (/usr/lib/./libgcj.so.3) 

Note that its complaining about a gcj library which if it was using your JDK is definately not somethin it should be trying to use. (gcj == gcc’s Java compiler)

To give us more info, can you do a

export LAX_DEBUG=1

and then run the installer and put the output in here? I’m sorry LAX_VM didn’t work, maybe I had that wrong. Here is a LAX_VM related thread https://www.genuitec.com/forums/topic/can-t-launch-executable-could-not-load-jvm-dll/&highlight=laxvm and it seems we did everything right…

[Scott Anderson]

If I remember correctly, another user worked around this by opening a shell, truncating his path so that it only contained the bin directory of his JDK installation, and then running the installer. Just another avenue in addition to the correct ones that Riyad suggested.

The ‘path sorting’ problem of InstallAnywhere is a real pain and we’ve been trying to get them to fix it since it was first noticed.

[Riyad Kalla]

Great suggestion!

[warren@roberts.name]

Whahoo….. The LAX_DEBUG gave me the answer. It was using the moldy old /usr/bin/java instead of looking in my classpath.

I followed ur suggestion that I only have the jdk that I want to use in my path. That still didn’t work but when I set LAX_DEBUG=1 I saw that it was using /usr/bin/java even though it found the other jdk just fine. I deleted /usr/bin/java and it installed ok.

Thanx for all the help
Warren

BTW: I really like the myeclipseide product

[Riyad Kalla]

Glad its working now!

[sankar]

actually me too face that pain when i install myeclipseIDe. i follow your steps, but i got hold with the same error after few seconds, Removing tmp install dir: “/tmp/install.dir.5759”. this is the final message, i set LAX_DEBUG =1;.
i have done everything waht you have said
but still lot of pain

please provide me a feasible solution
regards
sankar

[sankar]

i will post u the exact problem with the doc

[sankar]

When i try to install the myeclipse ide, these are the problems i faced,
at first i got error at the time when i press the enter key,
but after your suggestion i changes LAX_DEBUG =1;

still i got the same error but after few seconds,

Removing tmp install dir: “/tmp/install.dir.5474”

Sankar,
This is a damn annoying problem with the installer, it is trying to use GCJ to run itself instead of the Sun JRE you have installed. You can override this by setting the LAX_VM environment variable:

LAX_VM=/home/sankaralingam/packages/j2sdk1.4.2_06/bin/java

then running it, and if that doesn’t work, just download and use the Manual Install, it’s a 2-step process and included in the ZIP file is a step-by-step detailed install document.

[sankar]

Thanks for the help, timely help, finally i got escaped from the problem.

nice work riyad, thanks alot

regards

sankar
