Use of StAX
I tried to use StAX to modify a big XML file and I used the example EventProducerConsumer to start, as it implemented the same process I needed.
After some strange random failures I discovered that for big files you cannot use a FileInputStream to read the Xml file, as in the example (at leas in a Windows environment) . Using a FileReader I was able to process quickly a many big files (the dimension is limited only by the heap).
I don't know if in this was already noticed, as the FileInputStream works fine for small/medium sized file. So, just in case ......

Detection of encoding of XML file with the StAX parser
Hello!
I am using the StAX parser to read an XML file which can have different encodings.
I don't know how to detect the encoding before reading the file.
This is the way I instantiate the reader now:
XMLStreamReader xmlr = xmlif.createXMLStreamReader(new InputStreamReader (new FileInputStream(inputfile), "utf-8"));
Is there any way to make the reader detect the encoding with StAX? Is it possible detect the encoding with SAX or DOM?
Just paste some piece of code and you will help me a lot!
Thanks,
LaraXML parsers are supposed to auto-detect the encoding of their inputs. The SAX and DOM parsers built into Java, as well as others like Xerces, do that. I don't know whether your StAX parser does, but it should. There is a standard procedure for determining the encoding that is described in the XML spec.
However if you have malformed XML that fails to declare its encoding properly, then none of those parsers will be able to fix that problem for you.
Here's the simplified rule as it applies to most files: if the XML file doesn't have a prolog, or if it's prolog doesn't specify an encoding, the parser will assume the file's encoding is UTF-8. If the XML file does have a prolog that specifies an encoding, the parser will assume that encoding.
Unfortunately it is common for people to write XML files that don't declare an encoding, but to forget to encode the file in UTF-8. Then you have a file that is actually encoded in (e.g.) Windows-1252, but the parser believes it is UTF-8, and this fails when there are non-ASCII characters in the document. -
Hai
I want to know whether it is possible to validate a document as it is being built
using the stax api .We can validate a Document object before transforming it into an xml file using DOM.Is a similar approach possible in stax ?
Thanks in advanceValidating STAX parsers do exist. I just verified that with a 30-second Google search.

ClassCastException on Deployment in Weblogic 10.3
When I am deploying my application in Weblogic 10.3, I am getting below Exception.
weblogic.application.ModuleException:

Earlier I had no problem with Weblogic 8.1.I have the exact same issue. I'm trying to deploy a project that uses CXF 2.1 which uses the StaX parser. Here's what I've tried to do:

Extract data from xml file and insert into another exiting xml fil
hello,
i am searching extract data from xml file and insert into another exiting xml file by a java program. I understood it is easy to extract data from a xml file, and how ever without creating another xml file. We want to insert the extracted data into another exiting xml file. Suggestions?
Regards,
ZhuozhiIf the files are small, you can load the target file in a DOM document, insert the data from the source file and persist the DOM.
If the files are large, you probably want to use a StAX or SAX. -
Hi ,
I have an Xml file in the below format.
Could you please provide the java code to read the attributes from the xml

LakThere are at least four ways depending on what other XML technology you are already using or plan to use:
- SAX
- StAX
- DOM
- XPath
Nobody is going to just hand you the code. -
Using StAX with xslt transformations in the right way?
Hi!
What do I need to enable the stax functionality to transformations, and which transformer implementations is supporting this? (or is the implementation irrelevant)
I have made the following to create a StaxSource, but is it enought?
---8<---
private static XMLInputFactory inputFactory = XMLInputFactory.newInstance();
InputStream xmlInputStream = xmlUrl.openStream();
XMLStreamReader xmlStreamReader = inputFactory.createXMLStreamReader( xmlInputStream );
Source xmlSource = new StAXSource( xmlStreamReader );
transformer.transform(xmlSource, new StreamResult(writer));
---8<---I'm using:
org.apache.xalan.processor.TransformerFactoryImpland every thing seems to work very nice, but I'm not sure if I have done it in the right way and if it's something that I miss.
If I understand it correct normal transformations is transforming the xml to a Dom-tree but with StAX it shouldn't and be more memory efficient.
So anyone have any comments?
/PerIndeed, as DrClap has already stated, using a StAXSource will not guarantee streaming. All of the mainstream XSLT processors build some sort of DOM structure internally because, in the general case, XSLT requires random access on the input document. The only exception to this is the identity transform, which in most processors is done in streaming fashion --i.e., without actually creating an intermediate structure.

Creating XML from a POJO using StAX
Hi Experts,
I have a POJO and now want to create an XML which has the elements as that of the POJO using StAX.
Can anybody please help me out.
Thanks in advance.swati_pekam wrote:
Yes I totally agree with you, had initially used JAXB....however client needs StAX to be used.. :(What? Why?
Do you mean "client" as in "client side program"?
In that case, the requirement is bullshit, because the receiving end of the XML doesn't know which technology is used to create it.
Do you mean "client" as in "the people who pay me to do that"?
In that case, the requirement is bullshit, because they should not force you to use tools that are not fit for the task ..
Please clarify this requirement. Why exactly do you think (or does the client think) that you need to use StAX? -

Using Stax XMLStreamReader on fragments?
Im trying to use XMLStreamReader to parse small XML fragments that are streamed from a server to a client.
Sometimes the fragments refer to namespaces that are defined outside the fragment and XMLStreamReader
throws an Exception:
*Caused by: javax.xml.stream.XMLStreamException: ParseError at [row,col]:[1,18]*
Message: http://www.w3.org/TR/1999/REC-xml-names-19990114#ElementPrefixUnbound
Is there any way to define the namespaces and their prefixes programmatically? I dont want to disable validation.To answer myself. Found out that I can disable namespace awarenes without disabling all validation:
inputFactory.setProperty(XMLInputFactory.IS_NAMESPACE_AWARE, Boolean.FALSE);Would still rather like to define the namespaces.. -
Hi everyone,
I'm trying to find out if the J2 SDK supports Stax out of the box.
So far it seems, that even Java 5 only supports DOM and SAX.
Is this correct?
Thanks in advance,
Paulo PintoYes, I think StAX will become part of the Java platform in Java 6.0 (Mustang). WSDP 1.6 includes an EA implementation.

LinkageError while trying to use war-file bundled jars
Good day.
I have a servlet for which I want to use the latest JAX-WS 2.1.4 jars. I compile my servlet, and include in the WEB-INF/lib/ directory those same JAX-WS 2.1.4 jars. According to the classloading scheme under the SJWS v7.0, I can enable my servlet to actually use those jars, rather than the functional equivalent, but older, versions the container would provide, by setting delegate="false" in the servlet's sun-web.xml file.
http://docs.sun.com/app/docs/doc/819-2634/6n4tl5ko9?l=en&a=view
When I deploy this servlet, and a client makes a request of it, however, I'm getting an odd exception:

Read only part of a document with Stax
Hi,
I have some huge documents (~5GB) and I use Stax to read them.
My problem: I want to load only a part of the document.
I know the location that I should put the inputStream, so I skip half of the file.
Then I push data using xmlReader.hasNext(). After the first iteration though, I get the exception ->
javax.xml.stream.XMLStreamException: ParseError at [row,col]:[34,4]
Message: The markup in the document following the root element must be well-formed.
The original xml is like that:
<root>
<element id=1>
</element>
<element id=2>
</element>
<element id=3>
</element>
</root>And I pass to the xmlStreamReader
<element id=2>
</element>
<element id=3>
</element>So, I know why I get it. Because I include in the input stream only a part.
When it tries to read the element with id=3 , it says not well formed document.
which on one hand is correct, but on the other hand not important for me.
any possible solutions? How to disable the check of xmlstream reader or I don't what.
no, I cannot wrap a part of a 5Gb file to something else...That's not the point. It will be to slow...
That why I want to skip so much data in first place, to make it quick.
The problem is so annoying and a little bit stupid.
A solution would be to write my own parser, instead of using the XMLStreamReader, but then again, this is stupid, dirty, and duplicate of efforts...
-------part of the code--------
FileInputStream inputStream = new FileInputStream(filename);
inputStream.skip(skipBytes);
xmlReader = xmlif.createXMLStreamReader(filename, inputStream);
while (xmlReader.hasNext() && parsingComplete == false) {
xmlReader.next();
if (xmlReader.isStartElement()) {
parseStartElement(xmlReader);
continue;
}Thanks for the help and any opinions.
AndreasFollowing the tip about creating a new input stream, I've create a class that extends the FileInputStream, and now it works.
Extending just the InputStream was really slow. (remember the documents are huge "string" files)
The code:
XMLInputFactory xmlif = XMLInputFactory.newInstance();
xmlif.setProperty(XMLInputFactory.IS_COALESCING, Boolean.TRUE);
RootElementAppenderFileInputStream skippedInputStream = new RootElementAppenderFileInputStream(file, skipBytes);
xmlReader = xmlif.createXMLStreamReader(file.getAbsolutePath(), skippedInputStream);
while (xmlReader.hasNext() && parsingComplete == false) {
xmlReader.next();
if (xmlReader.isStartElement()) {
parseStartElement(xmlReader);
public class RootElementAppenderFileInputStream extends FileInputStream {
private ByteArrayInputStream rootElemStreamStart;
private boolean readingRoot = true;
public RootElementAppenderFileInputStream(File file, long skipBytes) throws FileNotFoundException, IOException {
super(file);
this.rootElemStreamStart = new ByteArrayInputStream("<O>".getBytes());
this.skip(skipBytes);
public int read() throws IOException {
if (readingRoot) {
int result = rootElemStreamStart.read();
if (result == -1) {
readingRoot = false;
} else {
return result;
return super.read();

Issue while starting AdminSerever using wlst commands
Hi, I am facing issue while trying to start the AdminServer and Managed Server via nodemanager using wlst commands. I have installelled WebLogic 11g on windows 2008 R2. Mentioned below are the steps that I followed:
1) In Nodemanager.properties files I set following parameters to true. I did this, so that nodemanager can start the server in case of crash.
CrashRecoveryEnabled=true
StartScriptEnabled=true
2) started nodemanager and then started AdminServer from the command prompt as follows:
nmConnect('weblogic','password','10.23.226.58','5556','IMDomain','E:\Oracle\Middleware\user_projects\domains\IMDomain','ssl')
nmStart('AdminServer')
I dont see any errors but it seems the AdminServer do Not start properly as in the cmd window I don't see any 'started successfully' message - the message remains as *"Starting AdminServer..."*
However in the adminServer logs I see that the status is Running (refer logs at the end) and I can also see it as Running in weblogic console.
I really didnt care if its not giving a success message in cmd window but the problem occurs when I start the managedServer. After starting the managed server in about 10 minutes, there is a stuck thread. (I guess it is 10 mins because Stuck Thread MaxTime value is 600).
If I set StartScriptEnabled=false, and start by directly running the startweblogic.cmd then it works fine.
I am struggling with this for last 1 week, appreciate any help.

Need help in use of XMLResolver resolveEntity method
Hi,
I have implemented the XMLResolver interface and set the resolver to XMLInputFactory.setXMLResolver method.
But when i try to execute the below program it throws exception.
Below is the code. Could anyone guide me how to proceed ...
