Can't get JEmplode to run in my office. Installed Java and tested as suggested on Java's website and all works fine. Donwloaded and double clicked JEmplode.jar and nothing happens? Did this at home last night too and everything worked perfect the first time. What am I missing here at the office? Running Win2000 Pro here at work and XP at home.

run it from a command line

Code:

---

java -jar jemplode.jar

---

still no JEmplode . The only thing that happens is a window with the folder for JAVA under thw WINNT folder opens.

Maybe this has something to do with it? I still have, and can open, JEmplode (Jempeg) Version 45 on my office computer. However, it's more like and installed program than just a .jar file. Maybe it's causing the new version to not open?

Drop the new .jar over the top of the old one, you might get a surprise.

yeah, try this. if you dont see the .jar, look further in the directory structure. i cant tell you off the top of my head where the .jar resides.

Dropped the new jar over the old jar and got this error message:

"unable to launch java application"

"unable to locate the applications "main" class "org.jempeg.empeg.jemplode.main" must be public and have a public static void main (string (jibberish) method (LAX)"

And, since I made no backup of the original .jar and overwrote it with the new one, now I can't even open the old version 45.

I'm beginning to wonder if the Jar you downloaded is corrupted. Try re-downloading it with a tool such as GetRight.

DL'd a new copy with GetRight and still the same. Noticed this though, right click and select properties says that it opens with IE. Is that right or should I choose another app?

I don't understand why the old versions have an .exe to open them and the new one opens by double clicking the .jar? If I click the old versions .jar, nothing happens either. I have to click the .exe to open them. I know it should work by d-clicking the .jar because that's how I launch it at home, but for some reason here at the office it isn't the same.

I'll try the uninstall and see if that works. Thanks

This actually sounds like the only functional JVM on the machine is the M$ one associated with the IE installation, which is crap anyway (missing and non-compliant classes). The association must have been changed by a later installation of IE after a SUN JVM was put on there.

I would uninst any SUN JVM, uninst V45, download the current J2SE JVM (either the compact JRE version, or the full blown JDK) and install it. Test out the JVM installation with one of the sample JAR apps, then create a directory for Mike's JAR. Drop the jar there. Right click on the JAR and try Open With... to see if it is properly associated with the JRE/JVM.
