recent jre's puts links to it's binaries into 'C:\ProgramData\Oracle\Java\javapath\' and add that folder to the system PATH variable before that the jre's put symlinks into the Windows\system32 folders, which automatically in PATH > As a temporary solution, I decided to wrap a JRE in an OpenJUMP distribution > (reinstalling java was not an option).

Have you some hints about how the .exe works, > and why it can behave this way ? not sure what software i created the exe w/ anymore, but i remember that it not only run the batch file, it was actually based on Launch4J or such and wraps a small java class that in turn executes the batch file. so it actually needs a java interpreter as well ;) always planned to make that more straight forward, but it did the trick so nicely. if it does not there is still the batch file, which will always work, you might have to edit JAVA_HOME though. rainy regards ..ede ------------------------------------------------------------------------------ _______________________________________________ Jump-pilot-devel mailing list Jump-pilot-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/jump-pilot-devel
