Unable to launch java application

Visual Paradigm UML Community Edition.

I downloaded and executed
vpumlce_20040414.exe

Which dumped alot of files into a directory i specified. I then executed
C:\I1083316273\Windows\vpumlce_20030207.exe

The installer completed with errors and suggested i look in the log file for these errors. Unfortunately I don’t know where the installer placed the log file. However, the installer did create the icons on my start menu and I tried executing “C:\Program Files\Visual Paradigm\Visual Paradigm for UML Community Edition 3.1\Visual Paradigm for UML Community Edition 3.1.exe”

But get the following error:
java.lang.ClassNotFoundException: RV

Any ideas. I’m really keen on trying out this software - please help.

Many tx.

Dear LM,

Please try to install VP-UML CE using the NoInstall zip file (you can find this option in the download page), just extract the zip file and then execute “Visual Paradigm for UML.exe”.

Regards,

Antony.

Hi,

9.0.2.822

Hi Andrija,

What version of JBuilder are you using? The SDE only works on version 9 and above.

Hi Martyn,

Yes, massage appears when JBuilder is active!!?

Andrija

Hi Andrija,

The file that you have downloaded (sdecejb_20040610.exe) is the SDE for JBuilder Community Edition. There is no Visual Paradigm for UML.exe. You run JBuilder first then invoke the SDE from JBuilder.

If this is not what you were looking for, you can still download the standalone Visual Paradigm for UML from our download page.

Hope this helps

Martyn

I have same problem,

I downloaded community edition “sdecejb_20040610.exe” and install it without errors. After start same massage appears “Unable to lounch java application” . After that i download NoInstall file, but I cudn’t find file “Visual Paradigm for UML.exe”. There is VPUML.exe file, but it cann’t be started.

Regards,

Andrija
