org.apache.xalan.xslt.XSLProcessorException: File xsl not found

Thanks Vohra and Pawan for the response,

Vohra: C:/source/Stylesheets/ABC.xsl does not generate an error

Here are the details of the issue with steps:

Though I am not sure do I really need to change from XSLTProcessor to Transformer:

1)When I load the home page, SecurityLogin.java servlet is loaded, details of SecurityLogin.java

a)It creates XML in the file

================================

//Create XML for SCR2

StringBuffer xmlSource = new StringBuffer("");

xmlSource.append("<?xml version = '1.0'?>");

xmlSource.append("<ROOT>");

XMLUtil.append(xmlSource,"SERVERNAME",request.getServerName());

XMLUtil.append(xmlSource,"PORTNUMBER",request.getServerPort());

XMLUtil.append(xmlSource,"APPNAME",coatsAppName);

XMLUtil.append(xmlSource,"LOGIN_FOOTER_1",sLoginFooter1);

XMLUtil.append(xmlSource,"LOGIN_FOOTER_2",sLoginFooter2);

XMLUtil.append(xmlSource,"LOGIN_FOOTER_3",releaseMsg.toString());

xmlSource.append("</ROOT>");

XSLTransformer xslt = (XSLTransformer)resourceManager.get(XSL_PROCESSOR_NAME);

where XSL_PROCESSOR_NAME is ::XSLTransformer which is an interface

XSLTransformer.java

public interface XSLTransformer {

public void process(XSLTInputSource xmlSource, XSLTInputSource xslStylesheet,

XSLTResultTarget resultTree) throws org.xml.sax.SAXException ;

public void process(String xmlSource, String xslStylesheet,

javax.servlet.http.HttpServletResponse response)throws org.xml.sax.SAXException, IOException;

public NodeList processXPath(String xpath, Node target) throws org.xml.sax.SAXException;

} //end interface

SecurityLogin servlet calls xslt.process method as below where xslt class name is ::class XalanXSLT

try {

//Create login screen and send

xslt.process(xmlSource.toString(), coatsStylesheetDir+SCR2_XSL, response);

} catch(SAXException e) {

e.printStackTrace();

}

===============================

2)Now, it goes to XalanXSLT.java in process method, where it creates Instance of the XSLT processor, Creates and send page by processing data and XSL stylesheet.

public void process(String xmlSource, String xslStylesheet, javax.servlet.http.HttpServletResponse response)

throws org.xml.sax.SAXException, IOException {

//Create reader for xmlSource

Reader reader = new StringReader(xmlSource);

//Get output stream from the response object.

response.setContentType("text/html");

OutputStream out = response.getOutputStream();

//Create Instance of the XSLT processor

XSLTProcessor processor = org.apache.xalan.xslt.XSLTProcessorFactory.getProcessor();

//Create and send page by processing data and XSL stylesheet.

processor.process(new XSLTInputSource(reader), new XSLTInputSource(xslStylesheet), new XSLTResultTarget(out));

} //end process

3)The above code in application works PERFECTLY fine on Weblogic 6.1 which uses JDK 1.3 and above all code uses xalan.jar and xerces.jar which has the following details:

-Xerces.jar contains Xerces_Ver_1_1_3.info file which means it is version 1.1.3

-Xalan.jar contains XSLTInfo.properties file which states below details

# XSLT Properties

# See also: org.apache.xalan.xslt.XSLProcessorVersion

version=1.0

vendor=Apache Software Foundation

vendor-url=http://xml.apache.org/xalan

4)When I deploy the application as it is without changing anything, in Weblogic 8.1 sp4 which uses jdk142_05, it gives the following error on Weblogic console

SecurityLogin.java, calling xslt.process.....

SecurityLogin.java, StylesheetDir is ::C:/coatssource/source/Stylesheets/

SecurityLogin.java, SCR2 is ::C:/source/Stylesheets/SCR2.xsl

where the file SCR2.xsl is there at the specified path.

5)I explored the error and it looks like it is a problem with parsing on WL 8.1(can be b'coz. of jdk142_05 or xalan/xerces version)

6)As per the document on bea site ( http://e-docs.bea.com/wls/docs81/xml/xml_apps.html#1082512 ), I feel that I should convert the Code From Using the Xalan API to JAXP 1.1 API

Question: DOES IT REALLY REQUIRED?

7)I tried converting the XSLTProcessor(Xalan 1.X) TO Transformer(JAXP 1.1) as per the above link above and changed the following in XalanXSLT.java process method

FROM

//XSLTProcessor processor = org.apache.xalan.xslt.XSLTProcessorFactory.getProcessor();

//processor.process(new XSLTInputSource(reader),new XSLTInputSource(xslStylesheet), new XSLTResultTarget(out));

TO

try {

Transformer trans;

TransformerFactory factory = TransformerFactory.newInstance();

trans = factory.newTransformer(new StreamSource(xslStylesheet));

trans.transform(new StreamSource(xmlSource), new StreamResult(out));

} catch (Exception ex) {

System.out.println("XalanXSLT, in Catch....");

ex.printStackTrace();

}

so the process method looks like

public void process(String xmlSource, String xslStylesheet, javax.servlet.http.HttpServletResponse response)

throws org.xml.sax.SAXException, IOException {

//Create reader for xmlSource

Reader reader = new StringReader(xmlSource);

//Get output stream from the response object.

response.setContentType("text/html");

OutputStream out = response.getOutputStream();

//Create Instance of the XSLT processor

//XSLTProcessor processor = org.apache.xalan.xslt.XSLTProcessorFactory.getProcessor();

//Create and send page by processing data and XSL stylesheet.

//processor.process(new XSLTInputSource(reader),new XSLTInputSource(xslStylesheet), new XSLTResultTarget(out));

try {

System.out.println("XalanXSLT, process(), xslStylesheet is ::"+xslStylesheet);

System.out.println("XalanXSLT, process(), xmlSource is ::"+xmlSource);

Transformer trans;

TransformerFactory factory = TransformerFactory.newInstance();

trans = factory.newTransformer(new StreamSource(xslStylesheet));

trans.transform(new StreamSource(xmlSource), new StreamResult(out));

} catch (Exception ex) {

System.out.println("XalanXSLT, in Catch....");

ex.printStackTrace();

}

} //end process

where xslStylesheet is SCR2.xsl which looks like, I am attaching the full content

10)Is it a problem with SCR2.xsl format.

11)Here is the PATH and CLASSPATH details:
