Bug in JRE 1.3.0_03 need JRE 1.3.1 but JWS won't load it.

I also have this problem and need to use the 1.3.1 JRE. I tried changing the j2se spec in the jnlp file to exactly match that which is reported by the java.exe - version command e.g. j2se version=1.3.1-b24. This does not work either.

Any thoughts for a usable work around would be most appreciated.

This would be a bug. Did the autoload feature work for you?

(For me it didn't so far)

How did you detect the JRE version? Only by the crash, or did you have a look at the console window (it can be activated by starting Web Start alone, and clicking the console check box in the files->preferences->advanced dialog).

Don't do this.

Like luongdang wrote, one place to change the JRE for Web Start is the File->Preferences->Java dialog, that you can access from calling Web Start itself (ie the JWS Application Manager).

There is the possibility to add (and even scan for) a new JRE.

After you added the 1.3.1 line, just remove all other lines to be sure that only the correct is left. Exit Web Start and relaunch it, look at the line in the console window if the correct JRE has been picked.
