I have a very strange problem and do not quite know what is the cause so I post here as I think this is the most responsive group I've ever seen. So:
1. I have a simple xsp page that collects data from request body, parses it to DOM structure and uses it later: <?xml version="1.0" encoding="ISO-8859-2"?> <xsp:page language="java" xmlns:xsp="http://apache.org/xsp"; xmlns:esql="http://apache.org/cocoon/SQL/v2"; xmlns:xsp-request="http://apache.org/xsp/request/2.0";> <xsp:structure> <xsp:include>java.net.*</xsp:include> <xsp:include>org.w3c.dom.*</xsp:include> <xsp:include>org.apache.cocoon.xml.dom.DOMStreamer</xsp:include> <xsp:include>org.apache.cocoon.xml.dom.DOMBuilder</xsp:include> <xsp:include>org.apache.cocoon.components.parser.Parser</xsp:include> <xsp:include>org.apache.cocoon.util.PostInputStream</xsp:include> <xsp:include>org.apache.cocoon.environment.http.HttpEnvironment</xsp:include> <xsp:include>javax.servlet.http.HttpServletRequest</xsp:include> <xsp:include>org.apache.xpath.XPathAPI</xsp:include> <xsp:include>javax.xml.transform.TransformerException</xsp:include> </xsp:structure> <xsp:logic> Document document = null; long maxNumerNr; String odbiorca; public Document GetInputStreamDocument() throws IOException { int contentLength = request.getContentLength(); if ( contentLength >= 0 ) { DOMBuilder builder = null; Parser newParser = null; try { HttpServletRequest request = (HttpServletRequest) objectModel.get( HttpEnvironment.HTTP_REQUEST_OBJECT ); PostInputStream anStream = new PostInputStream( request.getInputStream(), contentLength ); InputSource contentSource = new InputSource( anStream ); newParser = (Parser) this.manager.lookup(Parser.ROLE); document = newParser.newDocument(); builder = new DOMBuilder(newParser); newParser.setContentHandler(builder); newParser.setLexicalHandler(builder); newParser.parse( contentSource ); } catch (Exception e) { // ignore - return null } finally { if ( newParser != null ) this.manager.release((Component) newParser); } return builder.getDocument(); } return null; } </xsp:logic> <page> <mark1/> <xsp:logic> document = GetInputStreamDocument(); </xsp:logic> <mark2/> <page> </xsp:page> I've simplified the case of course Now when I call this xsp url in browser via standard Tomcat HttpConnector on port 8080 I get: <page> <mark1/> <mark2/> </page> Calling the same page via apache (mod_jk + mod_gzip) I get: <page> <mark1/> </page> In the first case there are no errors in Tomcat or Cocoon's log. While in second one I get following errors in Cocoon's log (error in Tomcat log following): ERROR (2002-09-05) 19:40.02:572 [access] (/cdn/data/order_create) Ajp13Processor[8009][4]/CocoonServlet:
