[#document: null]

Hi,
I try to to transfer access table data into an xml file using xerces dom parser, i get the following error. any ideas??

are you calling a "toString()" on a org.w3c.dom.Document?
if you do, then call a transform, you'll see the #document: null

X:parse returning [#document: null]

the following code is outputting [#document: null]
<c:import var="sampleXML" url="../common/sample.xml" />
<x:parse xml="${sampleXML}" var="parsedXML" />
yet, if it c:out the variable sampleXML, it spits out the xml I have in the sample.xml file. any thoughts why this might be happening?
thanks.

ya, it's valid, and im just using <c:out value="${parsedXML}" />
it's weird though. on my local i copy and pasted whats done here:
http://www.java2s.com/Code/Java/JSTL/JSTLparseXMLdocument.htm
and it still doesn't work, which would lead me to believe that it must be some config on my server? any thoughts?

DOM Document = null

I am trying to build a DOM document. The code I wrote (taken from examples) always returns a null.
There is no exception, everything seems OK but the document is null. It is unusable.

Any clue ?
Thanks in advance

Here is the code
package org.home.test.xerces;
import java.io.File;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.Document;
public class Builder {
     public static void main(String[] args) {
          Document xmlDoc=null;
          try {
          DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
          dbFactory.setValidating(false);
          dbFactory.setNamespaceAware(false);
          DocumentBuilder docBuilder = dbFactory.newDocumentBuilder();
          xmlDoc = docBuilder.parse(new File("E:\\arnold\\test.xml") );
          System.out.println("Document builder : " + docBuilder);
          System.out.println("Document implementation : " + xmlDoc.getImplementation());
          System.out.println("Document : " + xmlDoc);
          catch (Exception e) {
               System.out.println("Exception : " + e);
Result in the console is:
Document builder : org.apache.xerces.jaxp.DocumentBuilderImpl@1cb25f1
Document implementation : org.apache.xerces.dom.DOMImplementationImpl@e3b895
Document : [#document: null]

The returned Document isn't null. If it was, you'd just get "null" without the "[#document" part. Don't assume that a given implementation of Document will have a toString that spits back the XML.
Try printing out the doc's root element, or the names of the children.
You might also look into jdom. I know it has some prettyprint methods.

Null but not null Document on UNIX - URGENT

Hi, I hope someone can help me. I am using a simple DOMParser to read an xml file in. Now once I have this object I want to parse values out of it. Now on Windows this works fine. On UNIX I am getting something wierd. For instance:
If I call:
if(theDocument == null) {
System.out.println("IT IS NULL");
nothing happens
BUT
if I call
System.out.println(theDocument);
I get: [#document: null]
and if I try to call
theDocument.<anyMethod>
it throws a null pointer exception
BUT if I use XMLSerializer and serialize theDocument
it prints out the XML perfectly.
WHAT IS GOIN ON????????????
I am desparate as I am at the end of a project and this is this is the last hurdle.
If anyone knows why the object is null but isn't or anything I would greatly appreciate it.
THANKS!!!!

There is an issue, perhaps, because of the different EOL characters between Windows and Unix? If you wrote the parser yourself, does the code handle this difference? That's the only thing I can think of that would alter a parser working on a document between the two operating systems.

Webservices: returning xml document to client

Can anyone please help me to the following problem.
1. I have a java bean which i publish as webservice. I want to return an xml document on request from client(for time being my client is normal java client). when i call getDoc() from client i get classload exception. can anyone explain me why?
public org.w3c.dom.Document getDoc() throws java.rmi.RemoteException {
Document document = null;
DocumentBuilderFactory factory =
DocumentBuilderFactory.newInstance();
try {
DocumentBuilder builder = factory.newDocumentBuilder();
document = builder.parse( new File("C:\\data\\RND\\XmlParser\\XmlParser\\src\\xmlparser\\employer.xml"));
catch (Exception ex) {
return document;
2. if i have to send a xml file to clinet on request using web services(i assume i cant return an document as above), is it feasible(my xml file is a transaction file) to send a xml file as string?
3. how to transfer a xml file into a string?

I'm almost sure that the error is because the Document class is not supported by JAX-RPC (see page 384 of the Java Web Services Tutorial).
Try sending your XML as a String.
This code may help you to transform between XML and String and viceversa:
import javax.xml.parsers.*;
import javax.xml.transform.*;
import org.xml.sax.*;
import org.w3c.dom.*;
public static Document toXmlDocument(String xml) throws IOException, SAXException, ParserConfigurationException
StringReader reader = new StringReader(xml);
InputSource source = new InputSource(reader);
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document xmlDoc = builder.parse(source);
return ( xmlDoc );
public static String toXmlString(Node node) throws TransformerConfigurationException, TransformerException
StringWriter writer = new StringWriter();
DOMSource source = new DOMSource(node);
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer();
StreamResult result = new StreamResult(writer);
transformer.transform(source,result);
return ( writer.toString() );
}

Problem in Coverting XML String into Document

Hi,
I am getting some problem while parsing a String XML in to Document object.
CODE :
public static Document converDocument(String xml){
DocumentBuilderFactory factory=DocumentBuilderFactory.newInstance();
DocumentBuilder builder = null;
try {
builder = factory.newDocumentBuilder();
} catch (ParserConfigurationException e) {
e.printStackTrace();
Document document = null;
try {
document = builder.parse(new InputSource(new StringReader(xml)));
System.out.println("Document is after parsing ====>>>"+document);
} catch (SAXException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (IOException e1) {
e1.printStackTrace();
return document;
The xml which I am passing is :
<?xml version="1.0" encoding="UTF-8"?>
<note>
<to>Tove</to>
<from>Jani</from>
<heading>Reminder</heading>
<body>abc</body>
</note>
It is giving the document as null;
Can anybody please help?

Remove the "=" sign, this code will work :

      SOURCE XML lv_output_str

Prolem with usage of Document in jsp

Hi Ppl,
Following is a part of my code in jsp..
<%
try{
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
String filename = "D:\\integral\\1.0\\Resources\\ApacheTomcat4.0\\webapps\\examples\\jsp\\cal\\input1.xml";
Document doc = factory.newDocumentBuilder().parse(new File(filename));
out.println(doc);
%>
The problem is doc is getting null after this expression. The file is present in that location. I have imported org.w3c.dom.* as well. Is there any other configuration required...
Thanks in advance.

Hi,
After executing your code I get the following output:
[#document: null]
I guess it does not mean that document object is null because when I
add the following statement to your code it gives the expected output.
Element element = doc.getDocumentElement();
System.out.print("Document elelment = " +element);
Just add the above lines and check if you get the document element.

Dom parsing -- ruturning null?

when trying to parse an xml file using DocumentBuilder.parse, i dont get any exceptions, it just returns null. I wrote a succinct Test class to debug and still cannot find the problem. below is the output, and the method i wrote.
thanx for your help:-)
matt
output looks like this:
entering Test.parse
factory = org.apache.xerces.jaxp.DocumentBuilderFactoryImpl@7fa65e
builder = org.apache.xerces.jaxp.DocumentBuilderImpl@8385e3
doc = [#document: null]
leaving Test.parse
the parse method looks like this:
public Document parse(File xmlFile)
System.out.println("entering Test.parse");
DocumentBuilderFactory factory = null;
DocumentBuilder builder = null;
Document doc = null;
try
factory = DocumentBuilderFactory.newInstance();
builder = factory.newDocumentBuilder();
doc = builder.parse(xmlFile);
System.out.println("factory = " + factory);
System.out.println("builder = " + builder);
System.out.println("doc = " + doc);
}//end try
catch(Exception e)
e.printStackTrace();
}//end catch e
System.out.println("leaving Test.parse");
return doc;
}//end parse

The parse() method doesn't return null, "[#document: null]" is what's returned by toString() method when you print it. Call getDocumentElement() method for the document returned by parse() to get the root node of the document.

The stack trace below the "ORA-06502: PL/SQL: numeric or value error: character string buffer too small" error suggests that this is being generated by the Wf_Notification.NTF_Table call. Given the way you have described the problem, I would assume that the HTML generated by that call for the data in l_cells is exceeding the length of your l_result variable (32767).
Have you checked the length of the data generated by this call for a single record and then divided 32767 by that number to work out the maximum number of rows you can support with this call?
If it is simply that you have too much data for WF_Notification.NTF_Table to produce the table within the 32767 limit, you try generating the HTML in smaller chunks and adding them to the CLOB bit by bit. For example, if 10 records work, then generate the HTML for 10 records, chop off the </table> from the result and add it to the clob. Then do the next 10 records (without the header this time) and chop off the <table> and </table> tags and add that to the clob. When you are done, add the closing </table> tag to the clob and return it.
I haven't done this with returning a clob, but I have done this with shorter strings to generate a HTML table with the standard look and feel but with headers in different places than could be done by default.

}will use of JAXP / some other parser will do any good....any inputs???
thank you..
chintan.

I don't believe the Xerces parser can be configured to leave entity references as is if the entity reference is located in an attribute value. I think you might have more luck if the entity reference is inside an element.

12              System.out.println(doc.getDocType());
13              ....( i ) This program would does not work even while it was running on-line (has Internet access). The execution process would exit on line 10 but not sure whether it completes it or not. Don't understand why though?
( ii ) What is the difference between the two files as far as the format goes? I thought HTML 4.01 is equivalent to XHTML 1.0? In other word, they are already well-formatted and so they can be parse directly by an XML parser such as Xerces. In other word, it is not necessary to use tool such as Tidy to convert to clean up missing tags?
( iii ) why are the tags in the former file in capital? Do parsers in general distinguish tags in capital compared to lower case?
I am very new to XML parsing and would appreciate some guidances.
Thanks a lot,
Jack

Hi,
I am following a possible solution (http://devdiary.motime.com/post/471628/Why+implement+your+own+EntityResolver?) on how to redirect references to entities within an XML document to a local file but do not understand why it is not picking up the parsing file (former). Below is a complete change of ZipcodeTidy2JDomParser to include my own EntityResolver:
1 public class ZipcodeTidy2JDomParser {
2     public static void main(String[] argv) {
3         try {
4             File zipcodefile = new File("C:\\TEMP\\File zipcodefile = new File("C:\\TEMP\\Zipcodes Listing for California.txt"); // former
5             SAXBuilder saxBuilder = new SAXBuilder(false);
6             saxBuilder.setEntityResolver(new EntityResolver() {
7             public InputSource resolveEntity(String publicId, String systemId) {
8                 try {
9                     if (systemId != null && systemId.endsWith(".dtd")) {
10                         return new InputSource(getClass().getResource("E:\\Temp\\Software Development\\Download\\Forum\\html-loose.dtd").openStream());
11                     }
12                 }
13                 catch (IOException e) {
14                     e.printStackTrace();
15                 }
16                 return null;
17               }
18             });
19             InputStream is = new FileInputStream(zipcodefile.getName());
20      //     InputStream is = new FileInputStream(zipcodefile);
21             Document document = null;
22             try {
23                 document = saxBuilder.build(is);
24     //          document = saxBuilder.build(zipcodefile);
25             }
26             catch (JDOMException e) {
27                 e.printStackTrace();
28             } catch (IOException e) {
29                 e.printStackTrace();
30             }
31             finally {
32                 if (document == null) return;
33             }
34             System.out.println(document.getContent());
35             System.out.println(document.getDocType());
The output from running ZipcodeTidy2JDomParser is:
java.io.FileNotFoundException: Zipcodes Listing for California.txt. (The system cannot find the file specified)
        at java.io.FileInputStream.open(Native Method)
        at java.io.FileInputStream.<init>(FileInputStream.java:106)
        at java.io.FileInputStream.<init>(FileInputStream.java:66)
        at JDOMXPath.ZipcodeTidy2JDomParser.main(ZipcodeTidy2JDomParser.java:19){code}
Could any see where this issue is coming from?
The author of the same thread suggest that line 5 should add an extra parameter (SAXBuilder saxBuilder = new SAXBuilder(false, "http://www.w3c.org/TR/1999/REC-html401-19991224/loose.dtd"). However, the SAXBuilder constructor does not accept the second paramter. Any ideas?
Many thanks,
Jack

Org.w3c.dom.Document toString() ?

hi i have a constructed org.w3c.dom.Document var newDoc...
in ibm developerworks tutorial there is a line newDoc.toString() but that gives "[#document null]"
newDoc.getDocumentElement().getNodeValue() gives the xml string in jdk 1.4 but not in jdk 1.3 wih apache xerces 2.6.2
how to i get the xml in string output? (i do not wish to use sun java web service development platform)
please email responses to vishalrao at gmail dot com , thanks!

From what I saw there was no change and the document getNodeValue always returns null in jdk1.4 as well.
you can use the transform api to serialize xml into any serialized output form, including strings.
look into http://java.sun.com/j2se/1.4.2/docs/api/javax/xml/transform/Transformer.html

String to org.w3c.dom.Document conversion problem

Hi all
I am using JDK 5 and am having scenario to convert String to w3c.Document object , by the way of finding solution i got a code snippet in sun forum
final String xml = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><DATA>sample</DATA>"; // xml to convert
final DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
final DocumentBuilder builder = factory.newDocumentBuilder();
final Document document = builder.parse(new InputSource(new StringReader(xml)));
System.out.println(document);
But when i try to execute this code , am gettng output as null. , i dont know why this code behaving like that , can you please help me to solve the problem?
Thanks

Hi Prabu,
This is not the way you can print a DOM Document. You can do it using Transformer:
String xml = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><DATA>sample</DATA>"; // xml to convert
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse(new InputSource(new StringReader(xml)));
//Wong Way of printing a DOM Document. this equal to Object.toString(), Which is of no use for you.
System.out.println(document); // It will just print: [#document: null]
// Using Transformer to print DOM Document
Transformer transformer = TransformerFactory.newInstance().newTransformer();
Source source = new DOMSource(document);
Result output = new StreamResult(System.out);
transformer.transform(source, output); // This will print: <?xml version="1.0" encoding="UTF-8"?><DATA>sample</DATA>*Cheers,

Web Service Security is not working when migrating application from Tomcat

Hi,
We have a application running successfully in tomcat6 It calls a Webservice call through TIBCO BW interface.
When we deployed the same WAR file in Weblogic 10.3.2, it gives me a error on Prefix[ds] not able to locate namespace URI not found error.
IN Tomcat, its a existing application uses AxilUtility to get the soap messages after signing document for bothe encyption and decryption.
Please anybody help me out, is there any other jars needs to be locate in Weblogic to run this application. Its fine with Tomcat and gives error in Weblogic10.3.2
Please help me out
Thanks in advance

And i have the loggers which gives the system out statements. You can identify the difference in both logs is the sys out ...Convert Signed Document back to Soap Message.
IN tomcat i am getting the return object after calling the method
SOAPMessage signedMsg = (SOAPMessage) AxisUtil.toSOAPMessage(signedDoc);
But in Weblogic i am getting NULL. You can c in SOAPMessageImpl[SOAPPartImpl[null]]
