apache fop and security manager problem

[Roel Dillen <di...@scarlet.be>]

I wrote a servlet converting some xml to a pdf. The code (appended) is
basically a slightly modified version of the example code in the fop faq
about servlets.

When I start Tomcat 5.5 with a security manager I get this weird exception
(appended) when I try to access the servlet.

When I don’t start it with a security manager the servlet just works. 

 

I don’t get why.

 

 

I added following jars to my common/endorsed folder:  

serializer-2.7.0.jar

xalan-2.7.0.jar

xercesImpl-2.7.1.jar

 

The other jar’s that came with fop are in common/lib, contents of that
folder: 

avalon-framework-4.2.0.jar

batik-all-1.6.jar

commons-el.jar

commons-io-1.1.jar

commons-logging-1.0.4.jar

fop.jar

jasper-compiler-jdt.jar

jasper-compiler.jar

jasper-runtime.jar

jsp-api.jar

naming-factory-dbcp.jar

naming-factory.jar

naming-resources.jar

servlet-api.jar

xml-apis-1.3.02.jar

xmlgraphics-commons-1.1.jar

 

Any thoughts?

 

Sincerely

 

Roel
