running FOP multiple times, at one tomcat server(and one JVM) (IMPORTANT)
Hello, I run FOP from a JSP page, at Tomcat webserver. It works fine, til there is only one user at a time. But if 2 users want to use the fop converter at the same time, it fails, and says: type Exception report message Internal Server Error description The server encountered an internal error (Internal Server Error) that prevented it from fulfilling this request. exception javax.servlet.ServletException: duplicate class definition: org/apache/xalan/processor/TransformerFactoryImpl at org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:457) at org.apache.jsp.dmConvertXML2PDF$jsp._jspService(dmConvertXML2PDF$jsp.java:174) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:107) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.apache.jasper.servlet.JspServlet$JspServletWrapper.service(JspServlet.java:202) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:382) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:474) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:247) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:193) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:243) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:566) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:472) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:201) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:566) at org.apache.catalina.valves.CertificatesValve.invoke(CertificatesValve.java:246) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:564) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:472) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943) at org.apache.catalina.core.StandardContext.invoke(StandardContext.java:2344) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:164) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:566) at org.apache.catalina.valves.ErrorDispatcherValve.invoke(ErrorDispatcherValve.java:170) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:564) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:170) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:564) at org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:462) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:564) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:472) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:163) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:566) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:472) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943) at org.apache.catalina.connector.http.HttpProcessor.process(HttpProcessor.java:1011) at org.apache.catalina.connector.http.HttpProcessor.run(HttpProcessor.java:1106) at java.lang.Thread.run(Thread.java:484) root cause java.lang.LinkageError: duplicate class definition: org/apache/xalan/processor/TransformerFactoryImpl at java.lang.ClassLoader.defineClass0(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:486) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:111) at java.net.URLClassLoader.defineClass(URLClassLoader.java:248) at java.net.URLClassLoader.access$100(URLClassLoader.java:56) at java.net.URLClassLoader$1.run(URLClassLoader.java:195) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at org.apache.catalina.loader.StandardClassLoader.findClass(StandardClassLoader.java:671) at org.apache.catalina.loader.StandardClassLoader.loadClass(StandardClassLoader.java:1090) at org.apache.catalina.loader.StandardClassLoader.loadClass(StandardClassLoader.java:989) at org.apache.catalina.loader.StandardClassLoader.loadClass(StandardClassLoader.java:1073) at org.apache.catalina.loader.StandardClassLoader.loadClass(StandardClassLoader.java:989) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1293) at
Re: running FOP multiple times, at one tomcat server(and one JVM) (IMPORTANT)
thanks, but i solved the problem. i had to put these row, into my FOP executer method: org.apache.fop.messaging.MessageHandler.setID(true); BR, Fishy J.Pietschmann wrote: Fischer Tibor wrote: I run FOP from a JSP page, at Tomcat webserver.

But if 2 users want to use the fop converter at the same time, it fails, and says: ... javax.servlet.ServletException: duplicate class definition: org/apache/xalan/processor/TransformerFactoryImpl This is a problem with the Tomcat classloader loading a Xalan class. It has absolutely nothing to do with FOP. Ask the Tomcat people for help. If you are using Tomcat 4.0.3, they'll probably tell you to try 4.0.4b2. Another possibility is that you have JDK1.4 or for some other reason two different Xalan instances in the classpath(es). J.Pietschmann

Hello, How can i put entries into the bookmark of the pdf?? Thanks BR, Fishy
Re: problems with creating pdf
what version of FOP do you use?
try this code.
it works perfectly with 0.20.3 FOP
public static void execWFop(String xmlFile, String xslFile, String
outputFile){
try{
try {
javax.xml.transform.stream.StreamSource xmlSource=new
javax.xml.transform.stream.StreamSource(new java.io.File(xmlFile));
javax.xml.transform.stream.StreamSource xslSource=new
javax.xml.transform.stream.StreamSource(new java.io.File(xslFile));
javax.xml.transform.Transformer
transformer=javax.xml.transform.TransformerFactory.newInstance()
.newTransformer(xslSource);
transformer.setURIResolver(new TTURIResolver());
org.apache.fop.apps.Driver driver=new org.apache.fop.apps.Driver();
driver.setOutputStream(new java.io.FileOutputStream(outputFile));
driver.setRenderer(org.apache.fop.apps.Driver.RENDER_PDF);
transformer.transform(xmlSource,
new javax.xml.transform.sax.SAXResult(driver.getContentHandler()));
System.exit(2);
}
catch( Exception e ) {
e.printStackTrace(System.out);
}
}

We have the following problem using FOP:
First we tried to embed FOP into a small java programm:
package TestPackage;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import org.xml.sax.InputSource;
import org.xml.sax.XMLReader;
import org.apache.fop.apps.Driver;
import org.apache.fop.apps.Version;
import org.apache.fop.apps.*;
import org.apache.log.*;
public class Test {
public static void main(String[] args) throws Exception {
File fxml=new File(D:\\xslfoRef.xml);
File fxsl=new File(D:\\xml2pdf.xsl);
File fpdf=new File(D:\\ttt.pdf);
Logger log;
Hierarchy hierarchy = Hierarchy.getDefaultHierarchy();
log = hierarchy.getLoggerFor(fop);
log.setPriority(Priority.WARN);
Driver dr=new Driver();
dr.setLogger(log);
dr.setRenderer(Driver.RENDER_PDF);
InputHandler ih=new XSLTInputHandler(fxml,fxsl);
XMLReader p=ih.getParser();
dr.setOutputStream(new FileOutputStream(fpdf));
dr.render(p,ih.getInputSource());
}
}
The program can be compiled without any problems, but the pdf-file has 0
bytes. What is wrong?
We tried also to start FOP from the command line under dos and linux with the
parameters xslfoRef.xml and xml2pdf.xsl. The error message was : Master
-reference for fo:page -sequence matches no simple -page -master or
page -sequence -master.
Do you have any idea??
Thanks for your help,
Viktor und Marianne.
Re: to Fisher Tibor
sorry, just comment out that line
it should work without that. if not i send you that class too.
i dont think you need that.
