Default Error 523 & Java Loader

Please Login to Remove!

Having spent the weekend researching the reasons for my Pearl's crash I have come to the conclusion that Error 523 is generated when a Java module crashes and remains active instead of terminating. In my case it was Mobipocket Reader that was the guilty party though it seems that other apps are capable of producing the same problem.

First the good news - YOU MAY NOT HAVE TO RE-INSTALL THE OS.

Now the bad news, you need to use the command prompt and a piece of software called JavaLoader. First download jl_cmdr (posted below). Un-zip it and open the folder. Identify the file JavaLoader and copy it to the directory that comes up when you type 'command' into the 'run' utility available via the Start menu.

In the Dos-Prompt window (black screen that appeared when you typed 'command') type the following exactly as it appears below:

JavaLoader -USB DIR > DIR.TXT

Follow the screen prompts re passwords etc and, when finished, you will have a text file in the same directory as the JavaLoader app that lists all the modules on your BB.

Look through the list and the dates will identify the most likely culprit (probably the last module that was installed). Next type the following in the Dos-Prompt window:

JavaLoader -USB ERASE -F NAME-OF-MODULE-TO-BE-ERASED

If you are as fortuate as me then your little pal will spring back into life and you can reload the offending app.

Many thanks to all the other members of the forum whose posts got me working again - I hope that the summary above will provide a one-stop-shop for other suffers.
