[Mapserver-users] Java Mapscript craches JVM

[Frank Rittinger]

Hello list,

I have some JavaMapscript related questions.

I have a mapserver system based on JavaMapscript and the tomcat servlet 
engine.  My system is mapserver 4.0.1 on WinXP with Tomcat 5.

1) My java_mapscript.dll randomly crashes the JVM and hence the Servlet 
engine.  The crashes happen in different mapscript functions in native 
code.  Is this a threading issue, or do you have any suggestions?

2) How can I catch errors from mapscript, e.g. a mapfile cannot be 
rendered because it uses incorrect syntax?  The same as above: before I 
can get the error message from mapscript, it already killed the JVM.

3) Do I have to delete all mapserver related objects explicitly through 
methods like mapObj.delete() or does Java's GC-mechanism the job?

Might there be problems with the way I build my java_mapscript.dll?  If 
you have a JavaMapscript system running, would you share your 
java_mapscript.dll?

Regards Frank
