Jre1.4.1 FCS throws OutOfMemoryException with jdom

i'm using jdom to parse xml files. the files are not very large (max 500 KB). everything worked fine until I switched to jre1.4.1 where OutOfMemory errors are thrown all the time. even if i raise the heap to 256 or 512 MB (-Xmx521M).

I believe that your problem is most likely caused by a change in implementation of the StringBuffer class. I am also running into this problem and cannot migrate to 1.4.1. See bug 4724129 for more info.

XML validation with JDOM / JAXP

Hello,
I am trying to validate xml file against schema file. I decided to use JDOM and JAXP.
First question: is it a good choice?
I did a first attempt but not sure I have understood all what I am doing :(
First I have create a parser usinf org.jdom.*
SAXBuilder parser = new SAXBuilderThen I built my document:
Document doc = parser.build(myFile)These 2 steps are ok. But it does not do validation.
I saw in the JDOM documentation that I can set a validation flag to true. I did it. First problem, I got the following error from JDOMException: Document is invalid: no grammar found.
Is there a way to specify to the parser where to find the xsd file?
As I did not find answer to this question by myself, I tried implementing the Schema class from JAXP:
SAXBuilder parser = new SAXBuilder;
Document doc = parser.build(myFile);
Schema schema = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI).newSchema(schemaFile);
ValidatorHandler vh = schema.newValidatorHandler();
SAXOutputter so = new SAXOutputter(vh);
so.output(doc);It does the validation against the schema file specified but I am not really sure about what I am doing here. The last 2 commands are not clear to me :(
Then in my schema file, I have elements that have default value. I expected the following behavior: if the element is not in the xml file then the default will be used by the parser (and added in the tree). But it seems, it's not the case.
Any help/explanation will be really appreciated.

If only schema validation is required use the validation API in JDK 5.0.
http://www-128.ibm.com/developerworks/xml/library/x-javaxmlvalidapi.html
http://java.sun.com/developer/technicalArticles/xml/validationxpath/
For validation with JDOM, the following validation application explains the procedure:import org.jdom.input.SAXBuilder;
import org.xml.sax.SAXException;import org.jdom.*;
import java.io.*;
public class JDOMValidator{
public void validateSchema(String SchemaUrl, String XmlDocumentUrl){
           try{
SAXBuilder saxBuilder = new SAXBuilder("org.apache.xerces.parsers.SAXParser",true);<br/>saxBuilder.setValidation(true);
saxBuilder.setFeature("http://apache.org/xml/features/validation/schema",true);
saxBuilder.setFeature("http://apache.org/xml/features/validation/schema-full-checking",true);
saxBuilder.setProperty("http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation",SchemaUrl);
Validator handler=new Validator();
saxBuilder.setErrorHandler(handler);
saxBuilder.build(XmlDocumentUrl);
if(handler.validationError==true)
System.out.println("XML Document has Error:"+handler.validationError+""+
handler.saxParseException.getMessage());
else
      System.out.println("XML Document is valid");
          }catch(JDOMException jde){
            }catch(IOException ioe){
private class Validator extends DefaultHandler{
     public boolean validationError = false;
     public SAXParseException saxParseException=null;
public void error(SAXParseException exception) throws SAXException{
     validationError =true;
     saxParseException=exception;
public void fatalError(SAXParseException exception) throws SAXException {
validationError = true;
saxParseException=exception;
public void warning(SAXParseException exception) throws SAXException       {
public static void main(String[] argv)   {
   String SchemaUrl=argv[0];StringXmlDocumentUrl=argv[1];
   JDOMValidator validator=new JDOMValidator();
   validator.validateSchema(SchemaUrl,XmlDocumentUrl);

Better with JDom or not?

Hello, I have one function to create a XML structure without use JDom. I read my strings and I create a Xml. It's difficult but I have already done. But my question is if it's easyer use JDom and create a new function.
Here my String
Name
Name.Surname
Name.Surname,Second
Name.Surname.First
Name2
Name.Surname
Name2.Surname.Folder
Name2.Structure
I want this Xml:
<Cuenta id="xx" label="xx1">
<node label="Borrador"></node>
<node label="Name">
    <node label="Surname">
              <node label="Second"</node>
              <node label="First"></node>
    </node>
</node>
<node label="Name2">
    <node label="Surname">
              <node label="Folder"</node>
    </node>
    <node label="Structure"></node>
</node>
</Cuenta>Exist any easy way to do that? Or it's better if I continue with my method(it's difficult and if I have to change something I have to change a lot of things. I want one function to create that dinamicaly, not always is the same list. My function do dinamicaly but it's not very clear for other people.
Thanks!

Now I'm creating manually and then I use JDom to transform to Xml and edit if I have to change something. You said that you would use JDom to create. To say the truth I'm a newbie with JDom, and I know how can create a very simple document, but not how can create this Xml starting with my list. I have to use split to separate the folders and ..... but I don't know how can create the Xml.
Now I have my old solution but if you see easy that this function using JDom, can you say me how can I do or some
recommendations. Or if you show veryvery easy you can put the code, just kidding, hahaha (don't worry it's enough with some recomendations).
This is my actual code, has you can see it's a little complicate, I think that with JDom the code will be much more understandable.
public static String crearStringXML(lista) throws MessagingException, IOException
                java.util.Collections.sort(lista);//order the lsit
               String textOut="<Cuenta id=\"cuenta"+id+"\" label=\""+user+"\">";
               String[] oldPath = new String[0];
               String[] newPath=null;
               for(String path : lista) {
                    newPath = path.split("\\.");//dvide the folders
                  int matchLen = 0;
                  // To calculate how many are the same
                  while(matchLen < oldPath.length && matchLen < newPath.length && oldPath[matchLen].equals(newPath[matchLen]))
                          matchLen++;
                  for(int i = matchLen; i < oldPath.length; i++) {
                       textOut += "</node>";
                  for(int i = matchLen; i < newPath.length; i++){
                     textOut += "<node label=\"";
                     textOut += newPath[i]+"\">";
                 oldPath = newPath;
               for(int i =0;i< newPath.length;i++)
                    textOut +="</node>";
               textOut += "</Cuenta>";
               return textOut;
          }Thanks!

Can someone axplain to me what can happen ?
Thank's

What's this element ?
My schema is indicated by the xsi:schemeLocation attribute of my root-element .

Modifying XML files with JDOM

Hi:
I've been trying to get up to speed with JDOM, and while it seems pretty intuitive, I've been having a problem w/ modifying XML documents.
Namely, once I get a Document object from a (skeleton) XML file, do changes made to the Document object through, say, addContent() propagate to the original file? My gut feeling is no, although this was certainly what I had expected initially.
Here's a code fragment of what I had tried to do to populate a barebones XML file:
               Document doc = builder.build(output);
          // add 100 elements, all the same
          for (int count = 0; count < 100; count++)
               Element curr = new Element("book");
               // create child nodes for book
               Element title = new Element("title");
               title.addContent("Book " + (count + 1));
               Element author = new Element("author");
               author.addContent("Author " + (count + 1));
               Element price = new Element("price");
               price.addContent("Price " + (count + 1));
               curr.addContent(title);
               curr.addContent(author);
               curr.addContent(price);
               doc.getRootElement().addContent( curr );
          }

Mikael,
This sounds like one of the many quirks (perhaps bugs) related to how FrameMaker handles non-FM files in books. The current book model doesn't play well with XML files as chapters and this seems like yet another problem. Apparently, if an xref does not target another .fm file in the book, Frame assumes that the target file is not in the book and therefore will not be in the book PDF.
There have been discussions here about this in the past. The solution that I use is to run an API client before publishing that converts all XML files to .fm files, and redirect all xrefs appropriately. Then, book features work as expected and PDFs come out as normal. This is not feasible, however, without the automation from the API client.
There may be some who would say that the best approach is to use XML and books the way that the designers did account for... that is, the whole book becomes an XML document with entity references to the separate chapters. In my work, though, this model was not appropriate... rather, I needed a binary FM book to act like a book, except with XML files as chapters. So, I think I understand your situation.
Is API programming or FrameScript an option for you? I think it may be the only way to get what you are looking for.

Please, if you have ever used schemas with JDOM !!!!!!

How can we validate a document which refers to a schema rather than a DTD with JDOM ?
I tried to do that but an error occured, telling to me that my root element isn't declared.

Transformation with JDOM (off-topic)

Hi All,
I am wondering if anyone could advice me on how to carry out transformation in a JDOM enviornment. I am familiar with querrying data using XPath with JDOM.
Any tutorial or online reference material would be very much appreciated.
I am running Netbeans 6.1, J2EE 5 Glassfish on Windows XP platform.
Many thanks,
Jack

It contains the [org.jdom.transform|http://www.jdom.org/docs/apidocs/org/jdom/transform/package-summary.html] package with classes to do basic transformation. As the documentation says:
Classes to help with transformations, based on the JAXP TrAX classes. JDOMTransformer supports simple transformations with one line of code. Advanced features are available with the JDOMSource and JDOMResult classes that interface with TrAX.

Can i do this with jdom

Hi
i need to open an xml file, then modify it and then put its content into a string without modifying the physical file.
Can i do this with jdom?
I know that i can use some methods to build an object from a physical file, and also modify it, but then can i get the full content and put it into a string?
Thanks

Yep, you can do that with JDOM. U can use org.jdom.output.XMLOutputter to put the modified contents into a String. (Using a StringWriter)

How To read an XML file with JDom

I have read through some tutorials after installing JDom on how to read an existing XML file and I was confused by all of them. I simply want to open an XML file and read one of the node's content. Such as <username>john doe</username> this way I can compare values with what the user has entered as their username. I am not sure were to start and I was hoping someone could help me out.
I know that this seems like an insecure way to store login information but after I master opening and writing XML files with JDom I am going to use AES to encrypt the XML files.

Here is a test program for JDom and XPath use considering your XML file is named "test.xml" :import org.jdom.input.*;
import org.jdom.xpath.*;
public class JDomXPath {
public static void main(String[] args) {
SAXBuilder saxBuilder = new SAXBuilder("org.apache.xerces.parsers.SAXParser");
try {
   org.jdom.Document jdomDocument = saxBuilder.build("test.xml");
   org.jdom.Element usernameNode = (org.jdom.Element)XPath.selectSingleNode(jdomDocument, "//username");
   System.out.print(usernameNode.getText());
} catch (Exception e) {
   e.printStackTrace();
}(tested with Eclipse)

try:

with the size of the indent you require.
You dont really need the line: serializer.setIndent(true); if u use this constructor.
Hope this Helps

Deserialization Problem with JDOM Document

HI,
I am using weblogic7.0 and i have created my own class which implements serializable. I set the object of this class in the ObjectMessage and send it across. Sometime i have to send some vector,sometimes string and sometime a XML document. So i can set these type of objects in my custom serializable object and send it. For sending XML , either i can send it as a string or as u said as Document object. But i want to do send it as a Document object. So i have created a an object of "org.jdom.Document" which implement serializable and setting this object into my custom object and sending this custom object in the objectmessage. But then weblogic throws some exceptions which has to do with deserialization.I am printing the exception below. (without the object of org.jdom.Document this custom object reaches safely and happily:))........can you or anybody tell me what could be the reason..

Are you sure that your object gets serialized in the first place? You could use the writeObject method (explained in Javadoc for java.io.Serializable) to snoop the process.
I am actually surprised you can serialize a DOM document.

.This program would work on the same document without the default namespace, hence, it would not be necessary to include ns prefix along in the XPath statements (line 6-7) either. Moreover, I was using org.apache.xerces.parsers.SAXParser to have successfully retrieve content of <a> from the same document without default namespace in the past.
I would like to achieve the following objectives if possible:
( i ) Exclude DTD and namespace in order to simplifying the parsing process. How this could be done?
( ii ) If this is not possible, how to include it in XPath statements (line 6-7) so that the value of <a> is picked up correctly?
( iii ) Would changing from org.apache.xerces.parsers.SAXParser to org.ccil.cowan.tagsoup.Parser make any difference as far as using XPath is concerned?
( iv ) Failing to exlude DTD, how to change the lookup of a PUBLIC DTD to a local SYSTEM one and include a local DTD for reference?
I am running JDK 1.6.0_06, Netbeans 6.1, JDOM 1.1, Saxon6-5-5, Tagsoup 1.2 on Windows XP platform.
Any assistance would be appreciated.
Thanks in advance,
Jack

Here's an example of using a custom EntityResolver with the standard DocumentBuilder provided by the JDK. The code may or may not be similar for the parsers that you're using.
import java.io.IOException;
import java.io.StringReader;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.Document;
import org.xml.sax.EntityResolver;
import org.xml.sax.InputSource;
import org.xml.sax.SAXException;
public class ParseExamples
    private final static String COMMON_XML
        = "<music>"
        +     "<artist name=\"Anderson, Laurie\">"
        +         "<album>Big Science</album>"
        +         "<album>Strange Angels</album>"
        +     "</artist>"
        +     "<artist name=\"Fine Young Cannibals\">"
        +         "<album>The Raw & The Cooked</album>"
        +     "</artist>"
        + "</music>";
    private final static String COMMON_DTD
        = "<!ELEMENT music (artist*)>"
        + "<!ELEMENT artist (album+)>"
        + "<!ELEMENT album (#PCDATA)>"
        + "<!ATTLIST artist name CDATA #REQUIRED>";
    public static void main(String[] argv)
    throws Exception
        // this version uses just a SYSTEM identifier - note that it gets turned
        // into a file: URL
        String xml = "<!DOCTYPE music SYSTEM \"bar\">"
                   + COMMON_XML;
        // this version uses both PUBLIC and SYSTEM identifiers; the SYSTEM ID
        // gets munged, the PUBLIC ID doesn't
//        String xml = "<!DOCTYPE music PUBLIC \"foo\" \"bar\">"
//                   + COMMON_XML;
        DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
        dbf.setValidating(true);
        DocumentBuilder db = dbf.newDocumentBuilder();
        db.setEntityResolver(new EntityResolver()
            public InputSource resolveEntity(String publicId, String systemId)
                throws SAXException, IOException
                System.out.println("publicId = " + publicId);
                System.out.println("systemId = " + systemId);
                return new InputSource(new StringReader(COMMON_DTD));
        Document dom = db.parse(new InputSource(new StringReader(xml)));
        System.out.println("root element name = " + dom.getDocumentElement().getNodeName());
}

XSLT usage with JDOM problem

When I try to do an XSL transformation on a JDOM tree
using Oracle's xml classes from xmlparserv2.jar (includes
the javax.xml.transform api) I get the following:
java.lang.ClassCastException: org.jdom.transform.JDOMSource$DocumentReader
     at oracle.xml.jaxp.JXTransformer.transform(JXTransformer.java:201)
The same code works with xalan/crimson as well as saxon/aelfred, anyone
seen this and knows a solution? Code snippet:
private Frame transform(Document in, URL stylesheet) {
     TransformerFactory f = TransformerFactory.newInstance();
     InputStream s = stylesheet.openStream();
     Transformer transformer = f.newTransformer(new StreamSource(s));
     JDOMResult out = new JDOMResult();
     out.setFactory(new FPLNodeFactory());
     transformer.transform(new JDOMSource(in), out);
     s.close();
     return (Frame)out.getDocument().getRootElement().detach();
I was wondering if there is a problem with the Oracle's impelmentation or am I using it incorrectly.
Thanks.
Suhas.

This forum is mostly reviewed by folks using the XML features in the database (which basically means version 9.2). This is an XDK question--I would post it to Technologies > XML > General.
