Java Web Start problem (original) (raw)

? ?

I am trying to use the javaws command for the first time: I am all geared up to build some .jnlp files for my project only to find I can't get the simplest example from the demonstration site to work on my system (Windows XP, using either Mozilla 1.6 or Internet Explorer 6). The four examples just produce a grey "Java (tm) loading ..." message (which goes away after a few seconds, then nothing. The Application Manager example produces what looks to be the correct splash screen, then nothing.

The simplest case of the problem seems to be that if I type "javaws" from the command line, the Java Web Start splash screen appears, and then disappears. No error messages and no Application Manager!

I run Java SDK 1.4.2 (usually from within Eclipse) but also have 1.4.2_02 and 1.4.2_04 so there are about five javaws.exe's on my system, none of which seem to do anything.

Please help an experienced Java developer who had somehow never heard of JNLP until yesterday.
