http://nagoya.apache.org/bugzilla/show_bug.cgi?id=7962 Unable to use XML parser from inside the servlet code Summary: Unable to use XML parser from inside the servlet code Product: Tomcat 4 Version: 4.0 Beta 3 Platform: PC URL: http://physiologie.uni-ulm.de/kjr/ OS/Version: Windows NT/2K Status: NEW Severity: Blocker Priority: Other Component: Unknown AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] The servlet we created needs to parse the external XML documents, using the standard java parsing mechanism: DocumentBuilder db = DocumentBuilderFactory.newInstance().newDocumentBuilder(); Document doc = db.parse(myStream); It works well under Tomcat 3.3 that we are currently using. However it does not work under Tomcat 4.03, producing the following error message: java.lang.InternalError at org.apache.crimson.parser.Parser2.parseSystemId(Parser2.java:2653) at org.apache.crimson.parser.Parser2.maybeExternalID(Parser2.java:2622) at org.apache.crimson.parser.Parser2.maybeEntityDecl(Parser2.java:2525) at org.apache.crimson.parser.Parser2.maybeMarkupDecl(Parser2.java:1197) at org.apache.crimson.parser.Parser2.externalParameterEntity (Parser2.java:2768) at org.apache.crimson.parser.Parser2.maybeDoctypeDecl(Parser2.java:1155) at org.apache.crimson.parser.Parser2.parseInternal(Parser2.java:489) at org.apache.crimson.parser.Parser2.parse(Parser2.java:305) at org.apache.crimson.parser.XMLReaderImpl.parse(XMLReaderImpl.java:433) at com.icl.saxon.om.Builder.build(Builder.java:280) at com.icl.saxon.om.DocumentBuilderImpl.parse (DocumentBuilderImpl.java:35) at javax.xml.parsers.DocumentBuilder.parse(DocumentBuilder.java:86) at Agents.xml_robot._process(xml_robot.java:181) at Agents.xml_robot.process(xml_robot.java:74) at Agents.xml_robot.process(xml_robot.java:54) at Agents.channels.chAgent.go(chAgent.java:104) at Agents.iAgent.go(iAgent.java:194) at Agents.Agent.go(Agent.java:44) at c_paint.topology.makeView(topology.java:69) at c_paint.cServlet.get_t_protein(cServlet.java:323) at c_paint.cServlet.doPost(cServlet.java:165) at javax.servlet.http.HttpServlet.service(HttpServlet.java:760) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.apache.catalina.servlets.InvokerServlet.serveRequest (InvokerServlet.java:446) at org.apache.catalina.servlets.InvokerServlet.doPost (InvokerServlet.java:216) at javax.servlet.http.HttpServlet.service(HttpServlet.java:760) 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:190) 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:2343) at org.apache.catalina.core.StandardHostValve.invoke (StandardHostValve.java:180) 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:468) 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:174) 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:1012) at org.apache.catalina.connector.http.HttpProcessor.run (HttpProcessor.java:1107) at java.lang.Thread.run(Thread.java:579) As about my code, the exception is throwed from the line Document doc = db.parse(myStream); Other possibly relevant information: OS MS Windows NT 4.0 SP 5.0 java version "1.4.0-beta3" Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-beta3-b84) Java HotSpot(TM) Client VM (build 1.4.0-beta3-b84, mixed mode) Due this problem we cannot migrate from Tomcat 3 to Tomcat 4. -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
