RE: Embedded FOP question.
Thanks for your help! I needed to change it to use a ByteArray so that I could set the content length for IE. Other than that it worked great. Thanks again.

It looks to me like it can't be done with the XSLTInputHandler class because it requires java.io.File parameters. I'm looking at XSLTransform to transform the DOM document input to a DOM document containing FO output using the xsl file. Just wondering if this is the best approach and then how to best use the FO DOM document to output the pdf. If anyone knows where I can find some good sample code (or if you have a sample yourself), I would appreciate the tips. There is sample code in the archive at http://marc.theaimsgroup.com/?l=fop-userr=1w=2# http://marc.theaimsgroup.com/?l=fop-devr=1w=2# For producing and rendering a DOM, look up javax.xml.transform.dom.DOMResult in the JAXP documentation coming with your XSLT processor and look for render(Document) in src/org/apache/fop/apps/Driver.java Unless you need to manipulate the intermediate DOM, it is usually more effective to use SAX to tie the XSLT processor to the FOP driver, for example http://marc.theaimsgroup.com/?l=fop-userm=102400770318682w=2 J.Pietschmann
RE: FOPServlet and XML string
I'm having the same issues, so if you find a solution, please post. But, it seems like you could use the XALAN function XSLTransform to convert a DOM document or a string using an XSL file to either a FO file or another DOM document. XSLTInputHandler will only take java.io.File parameters, but I've seen examples of using the JAXP Transformer to do the job as well. See: http://www.devx.com/xml/articles/vp101201/vp101201-1.asp. It seems as if this could be modified to use a StringReader and/or StringWriter. Let me know if you have any luck.

Problem with javax.xml.transform.Transformer
I have two instances of Tomcat. One that has my development webapps and it is Tomcat 4.0.3. Another is empty and it is 4.0.4-b3. I put the FopServlet in the 4.0.4-b3 version and tested it out and it worked fine after some problems were resolved. Now, I've simply moved it into the webapps for my development server (4.0.3) and I start getting an error with a ClassNotFound exception on javax.xml.transform.Transformer. Anybody have any ideas? In both cases the xalan.jar is in my WEB-INF/lib directory.

Did you try giving the fo file a path? For example when I ran this I gave it fo=c:\temp\simple.fo and it worked (assuming my fo file was found in c:\temp.

My second question has to do with which XML object to use. Right now, I just have my XML in a file, but I want to generate it on the fly. The documentation says you can do this with DOM or SAX. Is there any problem doing it with JDOM? If not, does anyone know where I can find an example.
