DocumentBuilderFactory and TransformerFactory

I saw some coding like this:*
factory = DocumentBuilderFactory.newInstance();
builder = factory.newDocumentBuilder();
Document doc = builder.newDocument();
ByteArrayOutputStream baos = new ByteArrayOutputStream();
TransformerFactory tf = TransformerFactory.newInstance();
Transformer t = tf.newTransformer();
t.setOutputProperty("encoding","UTF-8");
t.transform(new DOMSource(doc),new StreamResult(baos)); String xmlString = new String(baos.toByteArray(), "utf8");
My questions are:*
1) Does the doc (Document)
contains the such header as:
*<?xml version="1.0" ?>*
2) Must the doc object host an XML string, or it can contain any type string(i.e., not necessarily an XML string)?
3) What is the purpose of using the transformer to transform the doc as:
t.transform(new DOMSource(*doc*),new StreamResult(*baos*));
4) Does the Transformer add the header <?xml version="1.0" ?> to the baos object?
Thanks

DocumentBuilderFactory and my applet

I am creating an applet that will read an XML file and parse the file to grab some info. I created the project in netbeans and i'm using the java.xml.parsers.DocumentBuilder and java.xml.parsers.DocumentBuilderFactory classes to do the work. When i run the applet and the config file is found it is read in just fine in the browser but i get a dozen errors in my server log saying "No route matches "/META-INF/services/javax.xml.parsers.DocumentBuilderFactory" with {:method=>:get}". This is bad because it makes the web app think an error occurred and it will spam our error email address. Is there something wrong with how i'm creating my applet or is this an issue with the web application?
Thank you,
Austin

Appetviewer fails on my applet:
runrun sun.applet.Main Pancet.class
Set uncaught java.lang.Throwable
Set deferred uncaught java.lang.Throwable
>
VM Started:
The application exited
yet it ran fine when I created it in JBuilder. Does
appletviewer require a "main" method? No.
My applet does
implement "runnable". Does the fact that I haven't
yet coaxed Mozilla into accepting the latest java
plugin have barring on the problem (this would seem
unlikely to me)? No, don't think so. Sounds like an uncaught exception to me. Maybe a security exception? What's the applet doing?

XML Parse issues when using Network Data Model LOD with Springframework 3

Hello,
I am having issues with using using NDM in conjuction with Spring 3. The problem is that there is a dependency on the ConfigManager class in that it has to use Oracle's xml parser from xmlparserv2.jar, and this parser seems to have a history of problems with parsing Spring schemas.
My setup is as follows:
Spring Version: 3.0.1
Oracle: 11GR2 and corresponding spatial libraries
Note that when using the xerces parser, there is no issue here. It only while using Oracle's specific parser which appears to be hard-coded into the ConfigManager. Spring fortunately offers a workaround, where I can force it to use a specific parser when loading the spring configuration as follows:
-Djavax.xml.parsers.DocumentBuilderFactory=com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl But this is an extra deployment task we'd rather not have. Note that this issue has been brought up before in relation to OC4J. See the following link:
How to change the defaut xmlparser on OC4J Standalone 10.1.3.4 for Spring 3
My question is, is there any other way to configure LOD where it won't have the dependency on the oracle parser?
Also, fyi, here is the exception that is occurring as well as the header for my spring file.
org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException:

I ran into this exact issue while trying to get hibernate and spring working with an oracle XMLType column, and found a better solution than to use JVM arguments as you mentioned.
Why is it happening?
The xmlparserv2.jar uses the JAR Services API (Service Provider Mechanism) to change the default javax.xml classes used for the SAXParserFactory, DocumentBuilderFactory and TransformerFactory.
How did it happen?
The javax.xml.parsers.FactoryFinder looks for custom implementations by checking for, in this order, environment variables, %JAVA_HOME%/lib/jaxp.properties, then for config files under META-INF/services on the classpath, before using the default implementations included with the JDK (com.sun.org.*).
Inside xmlparserv2.jar exists a META-INF/services directory, which the javax.xml.parsers.FactoryFinder class picks up and uses:
META-INF/services/javax.xml.parsers.DocumentBuilderFactory (which defines oracle.xml.jaxp.JXDocumentBuilderFactory as the default)
META-INF/services/javax.xml.parsers.SAXParserFactory (which defines oracle.xml.jaxp.JXSAXParserFactory as the default)
META-INF/services/javax.xml.transform.TransformerFactory (which defines oracle.xml.jaxp.JXSAXTransformerFactory as the default)
Solution?
Switch all 3 back, otherwise you'll see weird errors. javax.xml.parsers.* fix the visible errors, while the javax.xml.transform.* fixes more subtle XML parsing (in my case, with apache commons configuration reading/writing).
QUICK SOLUTION to solve the application server startup errors:
JVM Arguments (not great)
To override the changes made by xmlparserv2.jar, add the following JVM properties to your application server startup arguments. The java.xml.parsers.FactoryFinder logic will check environment variables first.
-Djavax.xml.parsers.SAXParserFactory=com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl -Djavax.xml.parsers.DocumentBuilderFactory=com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl -Djavax.xml.transform.TransformerFactory=com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl
However, if you run test cases using @RunWith(SpringJUnit4ClassRunner.class) or similar, you will still experience the error.
BETTER SOLUTION to the application server startup errors AND test case errors:
Option 1: Use JVM arguments for the app server and @BeforeClass statements for your test cases.
System.setProperty("javax.xml.parsers.DocumentBuilderFactory","com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl");
System.setProperty("javax.xml.parsers.SAXParserFactory","com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl");
System.setProperty("javax.xml.transform.TransformerFactory","com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl");
If you have a lot of test cases, this becomes painful.
Option 2: Create your own Service Provider definition files in the compile/runtime classpath for your project, which will override those included in xmlparserv2.jar.
In a maven spring project, override the xmlparserv2.jar settings by creating the following files in the %PROJECT_HOME%/src/main/resources directory:
%PROJECT_HOME%/src/main/resources/META-INF/services/javax.xml.parsers.DocumentBuilderFactory (which defines com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl as the default)
%PROJECT_HOME%/src/main/resources/META-INF/services/javax.xml.parsers.SAXParserFactory (which defines com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl as the default)
%PROJECT_HOME%/src/main/resources/META-INF/services/javax.xml.transform.TransformerFactory (which defines com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl as the default)
These files are referenced by both the application server (no JVM arguments required), and solves any unit test issues without requiring any code changes.
This is a snippet of my longer solution for how to get hibernate and spring to work with an oracle XMLType column, found on stackoverflow.

[Solution] DocumentBuilderFactory, Serialization, and WL 8.1 SP 2

<pre>
Hello All!
I finally have gotten my web services to work properly. All of my serialization
woes were caused by my using the javax.xml.parsers.DocumentBuilderFactory and
NOT setting the following options:
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setValidating(false);
factory.setNamespaceAware(true);
Yup. That's it. I saw this being done in one of the tech support people's examples:
private Document getDocumentWithWL(String resourceName)
throws Exception
weblogic.apache.xerces.parsers.DOMParser parser = new weblogic.apache.xerces.parsers.DOMParser();
parser.setFeature(
"http://apache.org/xml/features/dom/defer-node-expansion",
false );
parser.setFeature( "http://xml.org/sax/features/validation",
false);
parser.setFeature( "http://xml.org/sax/features/namespaces",
true);
parser.setFeature( "http://apache.org/xml/features/validation/schema",
true);
parser.parse(new org.xml.sax.InputSource(this.getClass().getClassLoader().getResourceAsStream(resourceName)));
return(parser.getDocument());
and decided to write the analog to this using the DocumentBuilderFactory:
private Document getDocumentWithDB(String resourceName)
throws Exception
DocumentBuilder db = null;
DocumentBuilderFactory fac = DocumentBuilderFactory.newInstance();
// Set params
fac.setValidating(false);
fac.setNamespaceAware(true);
db = fac.newDocumentBuilder();
Document doc = db.parse(this.getClass().getClassLoader().getResourceAsStream(resourceName));
return(doc);
Now my doc/lit web services are able to marshall data between the service and
client. I have to still use the DII dynamic proxy client method for invoking
the web service (SOAPElement!! grr).
Thanks to all who helped diagnose this problem. You know that you have this problem
when you see errors about "Local name of attribute can not be null ...." coming
out of weblogic's XML serialization code.
Hope this helps someone else out there

</pre>

Well basically that means there was a partial message that came in over a socket, and the server waited 60 seconds for the rest of the message, but it never arrived.
Was the server, or a client under heavy load? Did you notice any response time problems?

Can someone explain why one code works and the other one doesn't?

Hi,
I have been doing a little work with XML today and I wrote the following code which did not function properly. In short, it was as if there were elements in the NodeList that disappeared after the initial call to NodeList.getElementsByTagName("span"); The code completely drops through the for loop when I make a call to getTextContent, even though it is not a controlling variable and it does not throw an exception! I'm befuddled. The second portion of code works. For what it is worth, tidy is the HTML cleaner that's been ported to java (JTidy) and parseDOM(InputStream, OutputStream) is supposed to return a Document, which it does! So why I have to call a DocumentBuilderFactory and then get a DocumentBuilder is beyond me. If I don't call Node.getTextContent() the list is processed properly and calls to toString() indicate that the class nodes are in the list! Any help would be appreciated!

Thank you Dr but the following is true:
I placed this code in the for loop before I posted the question :
for (int i = 0; i < numSpanTags; i++) { // Loop falls through here!
      System.out.println("Span tag (" + i + ") = " + spanTags.item(i));
}And I receive 29 (The correct number) of non-null references to objects (Node objects) in the NodeList.
When I replace the exact same for loop with this code :
for (int i = 0; i < numSpanTags; i++) { // Loop falls through here!
      System.out.println("Span tag (" + i + ") = " + spanTags.item(i).getTextContent());
}Nothing prints. This discussion has never been about "clever means to suppress exceptions" it has been precisely about why a loop that has the
exact same references, exact same indices prints one time and doesn't print the other and does not throw an exception. If you can answer
that question then I am interested. I am not interested in pursuing avenues that are incorrect, not understood and most importantly shot from the hip without much thought.

Not getting required output from XML transform in servlet

I have an XML document and an XSL stylesheet that will produce the output I require when I use the Xalan in-line parser. However, I cannot manage to do the same in a servlet. I have trawled through loads of examples but can't find anything that works. It appears that the servlet is choking when I try to use:
Document document = builder.parse(datafile);
and the output in the browser is:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML><HEAD>
<META http-equiv=Content-Type content="text/html; charset=windows-1252"></HEAD>
<BODY></BODY></HTML>
Which bears no resemblance to what I am expecting.
I can provide contents of servlet source and xml files if someone can help, please.

Thanks for your comments.
I have tested the XML and XSL and they are OK but the servlet won't sned out the HTML as expected.
The servlet code is as follows (I haven't included the whole servlet - just the core of the body):
public class FormTwo extends HttpServlet {
public void doPost(HttpServletRequest req, HttpServletResponse res)
     throws ServletException, IOException, FileNotFoundException {
res.setContentType("text/html");
//PrintWriter out = res.getWriter();
PrintStream out = new PrintStream (res.getOutputStream());
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
TransformerFactory tFactory = TransformerFactory.newInstance();
try {
File stylesheet = new File("children.xsl");
File datafile   = new File("children.xml");
int NumChildren = Integer.parseInt(req.getParameter("Numchildren"));
String fullname = req.getParameter("Title") + " " + req.getParameter("Lastname");
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse(datafile);
// Use a Transformer for output
StreamSource stylesource = new StreamSource(stylesheet);
Transformer transformer = tFactory.newTransformer(stylesource);
DOMSource source = new DOMSource(document);
StreamResult result = new StreamResult(out);
transformer.transform(source, result);
}The XML is:
<?xml version="1.0"?>
<pagedef pagehead="Form two test page">

Clarification for the parser to be used in wls6.1

Hi,
Let me confirm whether my underdstanding is correct becuase it was misleading
on reading the FAQ of xml.Weblogic6.1 has two parsers xerces1.3.1 and weblogic
fast parser and one cannot use any other version of xerces and xalan and can use
any other parser by configuring in the xml registry and entering the DocumentBuilderFactory,SAXParserfactory
and TransformerFactory .Is this right? please endorse it.

I have found that all the Oracle SQL functions do work inside the SDO_RDF_MATCH procedure. I have used some of them as part of the filter parameter of the said procedure.

Enumeration mapping in message mapping

I have a source structure ABC that contains two fields. This structure needs to be transformed into two records that will store the field name of the source as well as the value. It actually creates name/value pair in the target interface. I wonder if message mapping could possibly handle that.
[Source]
ABC
---FIELD_A = 123
---FIELD_B = 456
[Target]
DEF[0]
---NAME = "FIELD_A"
---VALUE = "123"
DEF[1]
---NAME = "FIELD_B"
---VALUE = "456"

Adding properties to XML Registry

I'm using WLS 6.0. I was wondering if it is possible
to add more properties into the XML Registry on the console.
The two properties currently there are: DocumentBuilderFactory
and SaxParserFactory.
I'd like to add the two system properties: javax.xml.transform.TransformerFactory
and org.xml.sax.driver.
I know I can set these from the command line using the
-D option but I'd much rather have the configuration
in the console.
Can I do this? If so, how?
Thanks!

Follow-up: Even though it lists 4 missing required properties in the error, when I went back and added only the Value property, the red flags went away....

Escape XML problem

Hi,
This is a FAQ, however, I did a search before posting to the forum but could not find a definite solution. Here is what I am trying to do:
A webservice is returning a response XML and I am trying to display it on client console. I am able to display it properly on server side. The response is received by client of type 'Document'.
I create a transformer to get a string and display it on the console, and this is how it is done:
TransformerFactory tFactory =
TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer();
DOMSource source = new DOMSource(document);
StreamResult result = new StreamResult(System.out);
transformer.transform(source, result);I get the writer out of the result and do 'toString()' to get the text. but the output shows & lt; instead of < and similarly of > alsoWhat am I missing? and how do I fix this? Can anyone help me with this? Many of the posts direct to using the parser, i hope they refer to using DocumentBuilderFactory and then factory.parse(..) to get the document... but as I already have the document I did not use it...
Thanx in advance.

What you are missing is the explanation of why that is a problem.
It's normal to escape "<" as "<" if you are talking about data in a text node. But it is not normal to escape the "<" that starts a tag... unless you have an XML document embedded as a text node in an envelope-type document, in which case its tags are treated as text. This sort of thing happens in web services.
So, do you have a problem? I'm not convinced you do.

ParserConfigurationException:

Hi
I am using MessageDrivenBean and WebsphereMq as JMS provider.I wil get the messages as string which are in xml format.using TransformerFactory and Transformer i wil convert the string as Xml,after that i wil parse the nodes of these xml and insert the details in database.For parsing i am using documentbuilder object.
After processing few messages it is throwing ParserConfigurationException and it is happening rarely.Can anyone suggest me what will be the reason and how can i wil overcome this exception.
The below is the code snippet throwing the exception.
       DocumentBuilderFactory builderFactory = DocumentBuilderFactory.newInstance();
          TransformerFactory transformerFactory = TransformerFactorynewInstance();
                                               Transformer transformer = transformerFactory.newTransformer();
               StringReader stingReader = new StringReader(message);
               StreamSource src = new StreamSource(stingReader);
               ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
               StreamResult result = new StreamResult(outputStream);
               transformer.setOutputProperty(OutputKeys.INDENT, "yes");
               transformer.transform(src, result);
               ByteArrayInputStream inputStream = new ByteArrayInputStream(
                         outputStream.toByteArray());
               InputSource inputSource = new InputSource(inputStream);
               DocumentBuilder builder = builderFactory.newDocumentBuilder(); ----exception is throwing from here
               Document document = builder.parse(inputSource);

I am not having the stack trace.

Problem with com.sun.xml.parser.Parser

Attribute order changed

Hello all!
I'm developing a webapplication with JSP technology.
i have to manage xml files, change and rewrite them.
i use those pakage for manage and edit xml files :
"javax.xml.parsers.DocumentBuilder and DocumentBuilderFactory"
and that one for rewrite in a file:
"javax.xml.transform"
Now the problem is that the xml file edited had a particular element attribute order. the file rewrited change this order into an alphabetical order.
i want to mantein the previous order.
Is that possible? how?
Thanks!

No you get over it. The spec doesn't say it, but it is clearly an oversight by engineers more concerned with computer consuming XML then humans. One of the big selling points is that it is human readable and editable, this goes right against that.
Now that XML is more of a standard, programming languages and other things are being generated using it. Configuration files and all sorts of things. Consider you have a tag like <function name="" comment="" >
Suppose comment becomes really long while name is very short. Right now XSLT will reverse these attributes..now comment comes before the name and the file becomes unreadable....XML is used by humans too!
The spec also doesn't say you need it or not. Java and the rest of the community have actively decided to be like you, a complete dick, for no reason and not support it. Just lazying coding for no reason. I guess maybe open standards are a bad way to go huh? Man up and have the right attitude...no reason not to make it an option other then total disregard for other peoples real world ( not virtual specification ) problems.

URGENT start tag needs to be generated in xml output

I am getting the xml output as below
since my value for each element is empty doesn't generate the start tag. BUT I NEED START TAG also to be created with this xml file. What property need to specify while generating it thro' Transformer and TransformerFactory. Please help me
<?xml version="1.0" encoding="UTF-8"?>
<address>
<addressID/>
<streetNumber/>
<addressLine1/>
<addressLine2/>
<addressLine3/>
<city/>
<zipCode/>
<lastUpdatedUserID/>
<deletedFlag/>
<phoneNumber/>
<country/>
<state/>
</address>

I don't quite understand your question. You want to have the start tag of each element outputed or you want one root element start tag to be outputed?
If it's the first case, try separating start and end tags from your elements instead of having them combined, i.e. do the following:
replace
<addressLine1/>by
]<addressLine1>
</addressLine1>I don't know if this is the answer you expect, reply if not.

Xml parsing exception

Hi,
I am having xml content as a string like below
<?xml version="1.0" encoding="UTF-8"?>
<TransactionResponse>
<InterchangeControlHeader>
<AuthorInfoQualifier>00</AuthorInfoQualifier>
<AuthorInformation> </AuthorInformation>
</InterchangeControlHeader>
</TransactionResponse>
I am trying to parse this xml using below code
factory.setValidating(false);
factory.setNamespaceAware(true);
DocumentBuilder builder = factory.newDocumentBuilder();
StringReader XMLStringReader = new StringReader(xmlString);
InputSource XMLInputSource = new InputSource(XMLStringReader);
document = builder.parse(XMLInputSource);
I am using
javax.xml.parsers.DocumentBuilderFactory and DocumentBuilder for parsing but i am getting exception
"The markup in the document preceding the root element must be well-formed"
any idea what is missing?
Thanks

I am using websphere4.0.6,in standalone appln it works fine.
