I am developing two web based prototypes for rendering PDF using XSL-FO. First prototype is a Java Servlet deployed in Tomcat container in windows environment. The servlet renders PDFs to web as well as windows based clients. Everything works well, till I decided to add SVG elements to generate 3D charts. I am using pre-compiled version of FOP 1.0. Looking at the manifest file for FOP.jar, I noticed that jai_*.jar files have not been referenced. If I include following jar files, I am able to generate 3D graphs using SVG.
jai_codec.jar jai_core.jar jai_imageio.jar Are these jar files sufficient for FOP to process SVG elements? I thought that batik-all-1.7.jar should be sufficient to process SVG elements. I guess I was wrong. Second prototype is .NET based solution, where I have converted FOP 1.0 to a single .NET DLL using IKVM. Same issue here with SVG elements but even if I include the jai_*.jar files in my .NET dll, still the SVG elements are ignored. There are issues mentioned with class loader functionality in the following article. But this article was published in 2004, I bet there have been considerable improvements in IKVM since then. http://onjava.com/pub/a/onjava/2004/08/18/ikvm.html ================== Begin - Excerpt from the article Second is the ikvmc command, which can be used to convert Java bytecodes into .NET IL. Thus, you can convert a set of Java class files into a .NET assembly. Since this manner of use statically compiles the Java bytecodes, it's known as the static mode. Note that while the dynamic mode fully supports the Java classloader semantics, in the static mode, there are necessarily some limitations. Among the issues to watch out for is the fact that all classes are loaded by the bootstrap classloader. See the threads for the gory details. In brief, many Java programs assume this.class.getClassLoader() will return non-null. That, however, is not a valid assumption for classes loaded by the bootstrap loader. Also, while classloader functionality (such as Class.forName(..)) is available to use, and indeed can be used to load either statically compiled classes or Java bytecode, remember that loading classes out of .NET assemblies that are not referenced directly or indirectly from your application may not work without manual intervention. See the documentation for more detail on this and other hairy issues that arise when two different worlds collide! ================== End - Excerpt from the article I do understand that this is FOP user's email group, so IKVM related issue may not be answered, but if anyone has experience using SVG elements in .XSLT file, can point me to the right jar files (other than mentioned above). Thanks in advance for your help.
