Hello group,

I am pretty new to opencms and currently do not understand what I am 
experiencing right now, perhaps someone can give me a clue.

Environment:
Apache2.0.48, Tomcat 5.0.19, JDK1.4.1-b21 installed under SuSE Linux

Problem:
Exporting JSP-pages (nomatter if called .html or .jsp) results in the 
creation of a properly named file in the export directory.
I do not understnad why? Has it to do with a misconfigurated proxy 
connection between apache and tomact?

The content of the exported file is:
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>301 Moved Permanently</title>
</head><body>
<h1>Moved Permanently</h1>
<p>The document has moved <a 
href=" http://myserver/jps-page-exported.html?_flex_export=/jps-page-exported.html <http://myserver/jps-page-exported.html?_flex_export=/jps-page-exported.html&_flex_export_encoding=ISO-8859-1> &_flex_export_encoding=ISO-8859-1">here</a>.</p>
<hr />
<address>Apache/2.0.48 (Unix) mod_ssl/2.0.48 OpenSSL/0.9.6k DAV/2 
PHP/4.3.2 Server at myserver Port myport</address>
</body></html>

During the export sometimes the following error message is displayed:

com.opencms.core.CmsException: 0 Unknown exception. Detailed error: 
Redirect fails :/system/workplace/action/explorer_files.html.
root cause was java.lang.NullPointerException
