Hi everybody,

I am quite new to Eclipse RCP. As i got assigned to a long-term eclipse project i became a member of this forum and i hope to find support, when struggling with it (at the first glance it seems to be a quite complex issue).

Currently, i am trying to integrate a simple FOP code into Plugin and i have obviously some problems with the file access. The standalone code for generating the pdf looks like this:

            File baseDir = new File(".");
            File outDir = new File(baseDir, "out");
            outDir.mkdirs();

            File xmlfile = new File(baseDir, "input.xml");
            File xsltfile = new File(baseDir, "layout.xsl");
            File pdffile = new File(outDir, "ouput.pdf");

            FopFactory fopFactory = FopFactory.newInstance();

            FOUserAgent foUserAgent = fopFactory.newFOUserAgent();
            OutputStream out = new java.io.FileOutputStream(pdffile);
            out = new java.io.BufferedOutputStream(out);

            try {
                Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF, foUserAgent, out);

                TransformerFactory factory = TransformerFactory.newInstance();
                Transformer transformer = factory.newTransformer(new StreamSource(xsltfile));
                transformer.setParameter("versionParam", "2.0");
                Source src = new StreamSource(xmlfile);
                Result res = new SAXResult(fop.getDefaultHandler());
                transformer.transform(src, res);
            } finally {
                out.close();
            }

This code was working fine as a standalone java app. When integrating into an eclipse plugin the "."-notation for relative paths doesn't work anymore - apparantly instead of pointing to the project directory "." is interpreted as a path that looks like "homedirectory/."

Now i made up a solution for eclipse with setting the baseDir instance differently:

					URL baseUrl = Platform.getBundle("myPlugin").getEntry("");
					String base = FileLocator.toFileURL(baseUrl).getPath();
					
					File baseDir = new File(base);

The rest of the code is untouched. It works for opening the xml, xsl and pdf, but when the fop-processor tries to resolve the <import>-tags of the xsl-file, it is not able to find the referenced xsl-files. I assume, that fop running inside a plugin using also the "."-notation and fails with that.

Does anybody know a solution to this?

Thanks for any help!

Cheers,

I got it running with explicitly setting a base URL for FOP's user agent:

 
foUserAgent.setBaseURL(baseDir.getPath());

Still i would appreciate it, if somebody has some background information about this behaviour.

Cheers,
