Re: Invoking FOP from C++
Has anyone else had any experience calling FOP from C++? I am working on an existing product with a lot of C++ code. We are about to change the printing engine from something homegrown to FOP. I can only confirm the recommendations to embed the FOP into some sort of Java Daemon or Servlet. The performace gains from having FOP up running and eventually chaching stylesheets are significant. At the time I am considering to use HTTP/XML (Servlet embedding), ORB, IPC or RMI (Daemon embedding) as communication between the C++ system and Java FOP.

RE: Invoking FOP from C++
Has anyone else had any experience calling FOP from C++? I can only confirm the recommendations to embed the FOP into some sort of Java Daemon or Servlet. We are calling FOP from C++ without any problems. But we are also considering to use some daemon/servlet for the same reasons Anders Malmborg mentioned. My next approach is to download the source, write a Java wrapper for FOP We had to write Java wrapper class too. Some configuration settings are not available through command line switches, only by calling native Java methods. jan soltis - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Invoking FOP from C++
Have you looked into the Java Native Interface (JNI)? It works both ways. You can use it in Java to call native libraries and you can also use it to call Java code from C/C++. This should give you access to the page count property as well as controlling output creation. This link might help you get started: http://java.sun.com/docs/books/tutorial/native1.1/implementing/index.html Oosterbaan, Douglas S.

I've downloaded the binary and played around with it, and was considering using a fork() and exec(), but FAQ 2.8 states: It is best to avoid exec'ing FOP, use the library interface instead. FAQ 2.8 is in reference to the Jave Runtime.exec() call, but I assume the same would apply to a C++ exec(). Also, I need to get back the page count that is included in the results object returned by FOP. My next approach is to download the source, write a Java wrapper for FOP, and call my wrapper process either through an exec() or a CORBA call. But if possible I would like to just use the binary in it's original form. Has anyone else had any experience calling FOP from C++?

Of course there is a performance penalty, and the level of control isn't fine grain, but it's stable. /Gunnar - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
