    I recently updated to Java update 4 on 10.5.7 and Im not sure if this is related, Im making the assumption that it is, but now several Java webstart apps wont open. (.jnlp) They instead open with TextEdit rather than starting the app.

    Does anyone know what's possibly causing this issue? And if possible how I may fix it?

    OS-X just doesn't seem to recognise them.

    Thanks in Advance :)

    Fixed. Manually downloading it and installing the update fixed the issue.

    what did you do?

    I have two macs, one with the older version of java (i have not loaded the latest java update from the available software update) where there is a folder in the applications/utilities that has java web start. on this iMac (running leopard) the web application loads perfectly.

    my wife got a new macbook that has the latest update from java, and there is not a applications/utilities/java folder this time. it is just java preferences.

    the java web start application does not work properly on this site.

    was this your issue, and if so what did you do to fix it?

    thanks in advance...

    Almost the same problem here, although for me webstart apps are trying to open Parallels! Gonna try a manual update...

    I guess this is Apples attempt to put the final nails in the coffin for their Java support!

    Why are we still defaulted to 1.5JVM, why haven't we still got the new plugin 2 support, or Java 6u10+ goodness.

    Please, please Apple, return control of Java under OSX to Sun!!

    Same issue - Won't let me reinstall.


    Just saw you had the same issue I'm having now. It seems the new update is not working properly. I spent over an hour with Apple support and the only option they gave me is to back up and reinstall both of my computers. Can you describe how you did the manual update? I tried already downloading it from the Apple link and once I start running the installation it won't let me select my hard drive as the destination for the application. It says the application does not need an update.

    I use a couple of java web start applications for my business. Would appreciate any help with this.
