Exactly the additional work necessary to make this work. And when you want to upgrade, the same story all over again instead of just replacing a JAR. But it's up to you. > I would like to deploy the application to some users, and instead of > telling them to add some JAR-files to the classpath I would like them > to be able to just start one JAR-file which contains everything. > > Reason for that is, that most users don't know how to handle JAR- > files and classpath settings ... > > So I followed your advise and merged the XMLHandler file in the > JAR created by Eclipse, but I still get the same error messages. > > Am I missing something else? No, that should be it. But I can't tell from what I'm seeing if you made any other mistake along the way. If the error message still occurs there's still a problem with either the registration or the presence of the extension in the class path hierarchy. The only thing you can do now is setting breakpoints in org.apache.xmlgraphics.util.Service and org.apache.fop.render.XMLHandlerRegistry. You can also enable log level DEBUG on org.apache.fop.render.XMLHandlerRegistry which should tell you which extension classes were actually registered. > This is the content of the file now: > org.krysalis.barcode4j.fop.BarcodeXMLHandler > org.apache.fop.render.pdf.PDFSVGHandler > org.apache.fop.render.ps.PSSVGHandler > org.apache.fop.render.java2d.Java2DSVGHandler > org.apache.fop.render.pcl.PCLSVGHandler > org.apache.fop.render.afp.AFPSVGHandler > > Thanks, > Frank > > > Jeremias Maerki-2 wrote: > > > > I don't use Eclipse's export JAR feature so I can't tell if Eclipse does > > something wrong.
