So I presume you have some server-side middleware between them.
Actually tomcat is a servlet engine, not http server. Do you mean you don't want to use servlets?I want to be able to generate these PDF reports on the fly, however, I'm not really wanting to use Jakarta-Tomcat as a Http server to accomplish this.
FOP's command line interface assumes input parameters are file names, but you can easily write a wrapper, which uses System.in and System.out as input source and output stream respectively, see embedding page at http://xml.apache.org/fop/embedding.html, yes, that means embedding indeed.And I haven't figured out how to get the command line Fop to use standard io for the files. ie, specifying - as the filename dosn't work.
Well, FOP is written in java and embedding it into a servlet is obviously trivial, but not into a perl program. You can run it there as executable "java MyFOPWrapper", but getting JVM up for each request would be a performance nightmare. Alternatively you can consider developing multithreaded FOP servlet, but it looks like reinventing the wheel. What's wrong with servlet engine?I'm already using PostgreSQL and Apache with mod-perl to manage the data. I'd like to be able to have the mod-perl spit the XML through FOP as a filter and stream the results to the user.
