Jasperexport funktioniert in Eclipse aber nicht bei normalem Programmstart

[Tobias_Steidle]

Hallo Zusammen,
ich habe folgendes Problem.
Wenn ich aus Eclipse heraus meine Applikation starte, funktioniert der PDF-Export mit JasperReports ohne Probleme. Starte ich aber die Anwendung von der Kommandozeile aus, erhalte ich folgenden Fehler:

C:\Programme\Client\>C:\Programme\Java\jre1.5.0_08\bin\java -Xms40M -Xmx256M
-jar Client.jar
Exception occurred during event dispatching:

Es wird auch in Eclipse die JRE jre1.5.0_08 verwendet.
In beiden Fällen die selben Libs, es gibt soweit ich feststellen kann keinen Unterschied.
Weiß vielleicht jemand von euch einen Rat oder kann mit mir evtl. noch Fehlerquellen nennen?

Danke
Tobias
