Problems to run JavaHelp's search engine using usual server path

[kelox2000]

Hi there,

i ran my createt JavaHelp on my local machine without any problems.
Now I moved the whole stuff (HelpSet, TOC, HTML-files, Map,
JavaHelpSearch etc.) on a server.
When I start the HelpSet from my Local machine using:

URL url = new URL("file:\\\\server01\\java\\help\\helpSet.hs");

JavaHelp opens correctly, navigaton works fine, but the searchengine
throws an exception:

Exception while creating engine named
com.sun.java.help.search.DefaultSearchEngine for view:
javax.help.SearchView@cc5002
java.lang.reflect.InvocationTargetException

I mapped the server path to the drive letter Y and tried again:

URL url = new URL("file:Y:\\helpSet.hs")

the damn search engine works correctly!!!

can anyone help me?

thanx

Jay

An InvocationTargetException wraps another exception. What's the
wrapped exception? It would help if you could provide a complete stack
trace.

this is the complete stack trace:

I don't know the answer, but a quick search points to a lot of people
having the same problem (DefaultSearchEngine's constructor throwing an
InvalidParameterException) when:

1. There is a corrupted XML file.
2. There is a corrupted search index.
3. (???) Maybe a space in a path name, though this is unclear.
