Problem:Accessing the file system with servlets ???

Question

Hi...
I have a strange problem with my servlets that run on Win2000 with Apache and 2 Tomcat instances.
I cannot open files through servlets whereas exactly the same code lines work in local standalone java programm.
It seems to be somehting like a rights problem...but I dont know what to do.
thanks for any help
here are my configuration files for Apache and Tomcat:

Hi joshman,
no I didn't get error messages as the relevant lines for reading/writing where between try statements, but you were where right it was/is just a simple path problem.
I expected the refering directory without using a path to be the directory where the servlet is in, but it is not !!??
Do you know if I set this in the setclasspath.bat of tomcat ?
*** set JAVA_ENDORSED_DIRS=%BASEDIR%\bin;%BASEDIR%\common\lib ***
thanks again
