"Could not find main class"

Harvey_Babb · Post by **Harvey_Babb** » Wed May 04, 2011 3:05 pm

(I initially posted this on the "Beginners" forum without result and thought it might be more appropriate here.)

On trying to run either Rmir or Remote Master, I get a error box titled "Java Virtual Machine Launcher" that states "Could not find the main class. Program will exit."

I'm assuming that I did something wrong while installing, but don't know what or how to fix it!

How do I uninstall and start over? (Or is there some way to fix what's there?)

Running on an old Dell Dimension L800r running Win98 SE.

Any and all help appreciated!!

I didn't answer because I don't know that much about Java, but this was addressed in these two threads. Here are some things to try while we wait for the java guru (Greg) to see this.

I gather you installed the Java .zip, not the Windows .exe. What version?

I assume you double-clicked Setup.vbs to create the shortcuts for RMIR and Remote Master. Double clicking those shortcuts is generating those error messages?

Right-click on those shortcuts and copy'n'paste the contents of the "Target" and "Start in" fields. I hope those are the right names, haven't look at Win98 SE in a long time.

Also please provide the fully qualified path of the installation folder.

<I gather you installed the Java .zip, not the Windows .exe. What version?>

Correct, I installed "RemoteMaster.v2.00.zip"

<I assume you double-clicked Setup.vbs to create the shortcuts for RMIR and Remote Master. Double clicking those shortcuts is generating those error messages?>

Again, correct. Setup created a new group in the start menu "Remote Master" and created the icons.

<Right-click on those shortcuts and copy'n'paste the contents of the "Target" and "Start in" fields. I hope those are the right names, haven't look at Win98 SE in a long time.>

Target:
"C:\Program Files\Java\jre1.5.0\bin\javaw.exe" -jar RemoteMaster.jar -rm

Start In:
C:\JP1-Remote\RemoteMaster.v2.00

<Also please provide the fully qualified path of the installation folder.>

I created a new folder "C:\JP1-Remote" with all the zips (Remote Master, Maps and RDF's), then unzipped everything from there creating folders for each.

The folder with RemoteMaster.jar is:
C:\JP1-Remote\RemoteMaster.v2.00

Maps are in:
C:\JP1-Remote\Maps and Images for RM Version 1.31

and RDF's are in:
C:\JP1-Remote\RDFs required for RM-IR and IR - Version 1.32

(Yeah, I know it's ugly and long, but it was the quickest/easiest way.)

Thanks much for your time!

There may be other issues, but RM/RMIR requires Java 6 (a.k.a 1.6.?) or later. Upgrade your JRE, re-run setup.vbs and try again.

OOPS! What you just said is that I can't run it on this machine.
According to the Java site, the last version supported on Win98 is version 5.

I saw reference to a ".exe" version of RM; do you know off hand if that is "98 friendly" or am I just out of luck with this machine?
