ClassCastException on SAX parser factory newInstance

When trying to instantiate a parser factory, if none of the weblogic classes
have been accessed, the instantiation goes well. If a weblogic class has
been accessed, then I get the following stacktrace:
java.lang.ClassCastException:

I need help using a SAX parser

Hello,
I have a class that goes out to the web and retrieves an xml document w/o ever writing it to disk. I like to parse that object using SAX and a class that extends HandlerBase. Can any one show me how to parse an xml document that lives in memory rather than in a file? I've found many examples, but all of them assume you are reading from a file system. Any help is greatly appreciated.
Here is the jist of my code :
// Class 1 makes a request to another server based on some variable data. I've created a messenger object that handles all of the communications and returns the data in a DataInputStream
XMLMessage xml = new XMLMessage();
xml.createRequest(args[0],args[1],args[2]);
XMLMessenger messenger = new XMLMessenger(xml.getDoc());
DataInputStream dis = messenger.transferDocument();
ResponseObj resp = new ResponseObj();
resp.read(dis);
System.out.println(resp.getvalue1() + "*" + resp.getvalue2()+ "*");
// Class 2 is the ResponseObj and I want to use something similar to this read method, but
// I can't get it to work with a data stream, instead of a string that represents a file.
public void read(String filename) throws java.lang.Exception {
Class c = Class.forName("com.ibm.xml.parser.SAXDriver");
     org.xml.sax.Parser parser = (org.xml.sax.Parser)c.newInstance();
     parser.setDocumentHandler(this);
     parser.parse(filename);

Thanks for you help. I've modified my read() method to work like this :
org.xml.sax.Parser parser = new com.ibm.xml.parser.SAXDriver();
parser.setDocumentHandler(this);
InputSource is = new InputSource(dis);
parser.parse(is);
This makes sense, but I'm still not getting any thing returned from the startElement(),characters(), or endElement() methods. It reports no errors, it just doesn't happen. Do you have any suggestions on how to debug this? I'm stumped, but really need to get this working.

Sax parser problem

hi,
i am assuming the problem is with sax parser but i cant be sure. I am parsing a xml file (about 1.4MB) with some data in it. the parser i have created reads the xml file correctly for the most part but when at some point the
"public void characters(char buf[], int offset, int len) throws SAXException"
function stops working correctly....i.e it doesnt fully read read the data between the "<start>" and "</start>" element. say it reads about 100 id's correctly---for 101 ID it does this. This is just an example. Since, the problem might be with how :
"public void characters(char buf[], int offset, int len) throws SAXException"
function is reading the data i was wondering if anybody else had encountered this problem or please let me know if i need to change something in the code: here's a part of the code :
Bascially i have created three classes to enter data into three mysql tables and as i parse the data i fill up the columns by matching the column header with the tagName.

I haven't gone through your code but I also had a similar error....and the exception in my was because of an "&" instead of the entity reference & in one of the element values. I use a non-validating parser but if you use a validating one then this might not be the reason for your exception.

By the way, there is a new feature in Java 5.0 (Tiger) called "Annotations."
Since your code extneds DefaultHandler, you could specify a line with
@Override
before the definition of each of your methods. If you had used these, the compiler would have given an error since your methods did not override the methods of DefaultHandler.
(If your code implemented ContentHandler, by contrast, using @Override is invalid because you need to implement all of the methods defined in the interface definition.)
The other comment is that the safest way to handle characters() data is to use a StringBuilder/Buffer (StringBuilder is only valid in 5.0, StringBuffer has been around since Release 1.0) that you define in the startElement method. Use the append method to gather data presented to you in the characters() method and use toString() to harvest the data in the endElement method.

SAX Parser XML Validation Problems

Hi,
I’m having problems getting an xml document to validate within Weblogic 8.1. I am trying to parse a document that references both a dtd and xsd. Both the schema and dtd reference need to be substituted so they use local paths. I specify the schema the parser should use and have created an entityResolver to change the dtd reference.
When this runs as a standalone app from eclipse the file parses and validates without a problem. When deployed to the app server the process seems to be unable read the contents of the dtd. Its not that it cannot find the file (no FileNotFoundException is thrown but this can be created if I delete the dtd) rather it seems to find no declared elements.
Initial thought was that the code didn’t have access to read the dtd from its location on disk, to check I moved the dtd to within the deployed war and reference as a resource. The problem still persists.
Code Snippet:
boolean isValid = false;
try {
     // Create and configure factory
SAXParserFactory factory = SAXParserFactoryImpl.newInstance();
factory.setValidating(true);
factory.setNamespaceAware(true);
// To be notified of validation errors in the XML document,
// add a custom error handler to the document builder
PIMSFeedFileValidationHandler handler
= new PIMSFeedFileValidationHandler();
     // Create and Configure Parser
SAXParser parser = factory.newSAXParser();
parser.setProperty(JAXP_SCHEMA_LANGUAGE, W3C_XML_SCHEMA);
parser.setProperty(NAMESPACE_PROPERTY_KEY, getSchemaFilePath());
     // Set reader with entityResolver for dtd
XMLReader xmlReader = parser.getXMLReader();
xmlReader.setEntityResolver(new SAXEntityResolver(this.dtdPath));
// convert file to URL, as it is a remote file
URL url = super.getFile().toURL();
// Open an input stream and parse
InputStream is = url.openStream();
xmlReader.setErrorHandler(handler);
xmlReader.parse(new InputSource(is));
is.close();
// get the result of parsing the document by checking the
// errorhandler's isValid property
isValid = handler.isValid();
if (!isValid) {
LOGGER.warn(handler.getMessage());
LOGGER.debug("XML file is valid XML? " + isValid);
} catch (ParserConfigurationException e) {
LOGGER.error("Error parsing file", e);
} catch (SAXException e) {
LOGGER.error("Error parsing file", e);
} catch (IOException e) {
throw new FeedException(e);
return isValid;

Hi David,
I have checked the ejb-jar.xml file and there is no duplicate values in it and the other things is that the same application is been deployed on OAS 10G and websphere and its working fine. In the forum someone has replied to a similar problem that there is bug in Weblogic 10.3 and its CR no 376292. I am not sure about it, does anyone any information about it.
Thanks and Regards

SAX Parser throws NullPointerException

Hi.
I'm using WLS6.1 SP1 built-in XML SAX parser. The code is like,
SAXParserFactory factory = SAXParserFactory.newInstance();
XMLReader parser = factory.newSAXParser().getXMLReader();
// Add a error handler
eh = new MyErrorHandler();
parser.setErrorHandler(eh);
parser.setContentHandler(this);
// Enable namespace
parser.setFeature("http://xml.org/sax/features/namespaces", true);
// Enable validation
parser.setFeature("http://xml.org/sax/features/validation", false);
parser.parse(new InputSource(in));
The NullPointerException is thrown at -
org.apache.xerces.framework.XMLParser.parse(XMLParser.java:965)
after the end element of (</eb:MessageHeader>) before the start element of <SOAP-ENV:Header>.
The XML file is attached.
=====================================
However, I tried to parse this document on xerces parser 131.
It worked fine.
=====================================
Did I miss any thing? It seems like a bug to me.
Thanks!

SAX should mask the fact that some content is specified inside of a CDATA section.. It is just characters.
The safest way to process characters is to setup a StringBuffer or equivalent in the startElement method. There is a variation of the StringBuffer append method that has the same three parameters (char[], int, int) as the characters signature. The characters method may be called many times before you are given all of the content of the string. How it decides when to call you depends on the parser and is subject to change over time. But, if you accumulate the contents in each call of characters and do the toString() in the endElement method you are going to get the right content. Lots of people over the last year or so that I've been involved in this forum have had other ways they thought were better than this, but most of them have eventually tried and accepted this way because it works and their "better" way did not.
It looks like you got the content for the CDATA section (Please refer...).I'm not sure what your problem is.

But while executing this in XI I am facing an error as "XML not well formed" but I am not able to know why this error is comming.
Can you please throw some light why this error is happening.?IWhat us the error in the code and what should be the correct code?
Many thanks for the support that I got in past.

Just use characters() method for building string. Use endElement() to process that string.

}I am currently pulling out the package names, pulling out the classnames and then mapping these in a separate class - this works because the class and package names are declared in the same line, so if a package name appears in the package list 7 times, i know this package has 7 classes, and therefore i count the first 7 classes out of an array of all the classes and know that these are the right 7 for that package. However, the methods are a bit different:
What I would like to do is to: for every class make a hashmap which maps the class name onto an arraylist of the methods, but i think i'm getting confused with my for loops. Or even just keep a tally of how many methods each class has, then I can work it out as i did with the packages -> classes.
Does anyone know where im going wrong, or have any ideas at all?
Thank you for your time,
beccy

I don't know if stacks are specifically mentioned in any SAX documentation.
Basically, SAX sends you a stream of XML elements (open and close tags, characters, etc.), but it doesn't know anything about the underlying XML structure. You have to add that part (usually -- sometimes when writing a SAX application, you don't really care about the XML structure). XML structure is a tree.
If you've ever written a recursive function that spans a tree, you'll have an idea what to do. You can use a stack to keep track of where you are in the tree. For example, if you open tag A, then you're "in" the A element for subsequent content in that document; if you then open tag B, you're in the B element; but when you close the B tag, you need the stack to tell you that now you're back in the A element.
You may not need stacks, but it's likely. Find a good tutorial about SAX that mentions stacks and you'll be fine.

SAX Parser in Webdynpro for Java

Hi,
     Scenario : To get data entered in the Dynamic table of an online PDF form.
I have got the XML of the PDF form. The problem is with Parsing the XML to get the data.
I am using SAX parser. The code structure is as given,
public class Outercomp
    getPDFData(IS);    // IS is the Inputstream of the PDF XML
   // begin Others
   public static class inner extends DefaultHandler
        void getPDFData(InputStream IS)
              SAXParserFactory SAXfac = SAXParserFactory.newInstance();
              SAXParser SAX = SAXfac.newSAXParser();
              SAX.parse(IS, new Outer.Inner());
        void startElement()
             // some Code
Problem :
I am getting the below exception at calling the method 'parse'.
com.sap.engine.lib.xml.parser.NestedSAXParserException: Generic Exception: -> java.lang.NullPointerexception
I checked both 'IS' and 'new Outer.Inner()', both are not null.
Please give me a solution
Thanks,
Prabhakar

Hi Satyajit,
     ' DefaultHandler ' is a class, and I am extending it.
     First I missed it in the code, now I have changed it. Thanks for reminding me.
Thanks,

This parser takes 2 hours to laod file of size around 8MB.
ANy suggestions on improving performance of the parser.
ANy other approach I should be taking to load this file into DB.
We are using ORacle 9i DB with Character set UTF 8.
Thanks!

String buf = (new String(ch, start, length)).trim();
if (thisElement != "root"){
if ((buf.length() == 0) && (thisElement !="") ){
It run ok!
Thanks 58871!
Now, i want to export oracle table to xml file like :
<?xml version="1.0" encoding="UTF-8"?>
<root>
<emp>
<ename>aaa</ename>
<sal>3000</sal>
</emp>
<emp>
<ename>bbb</ename>
<sal>5000</sal>
</emp>
</root>
Can SAX export to xml format?

SAX Parser in OC4J

I'm trying to read a XML file in an EJB using a SAX parser.
I tried the following statement to create the reader
XMLReader xr = XMLReaderFactory.createXMLReader("oracle.xml.parser.v2.SAXParser");
but I obtain the following exception:
java.lang.ClassNotFoundException: oracle.xml.parser.v2.SAXParser
at org.xml.sax.helpers.XMLReaderFactory.createXMLReader(XMLReaderFactory.java:118)
The same works correctly from a command line application outside OC4J.
Is there another SAX Parser I can use in OC4J?
Andrea Mattioli

I'm also seeing the a similar problem trying to get my EJB to parse SAX using the Xerces parser. If I do
XMLReader myReader = XMLReaderFactory.createXMLReader("org.apache.xerces.parsers.SAXParser");
and place xerces.jar into $(OC4J_INSTALL_ROOT)\j2ee\home\lib then at runtime I get
java.lang.ClassNotFoundException: org.apache.xerces.parsers.SAXParser
This is despite the fact that calling Class.forName() on the same class name works fine. Setting the system property org.xml.sax.driver and calling createXMLReader with no parameters results in the same error.
I can force use of the Xerces SAX parser by bypassing the factory and just calling
XMLReader myReader = new org.apache.xerces.parsers.SAXParser();
but that seems a tad hacky and I don't want to hardwire SAX parser implementation choice into my code.
Is this a known bug?
Also which parser is getting used by default in OC4J i.e. if I don't set org.xml.sax.driver and use the no parameters variant of createXMLReader()?
Thanks

Sax parser problem plz help

hi !!!!!!!!!!!!
Im using a SAX parser to parse an xml file im successful in doing it i got tit parse after parising i want the value of a particular tag for example i have a tag as
<filtername>datasource</filtername>
i want datasource after parsing the xml and without using DOM concept how do i do it please help

hi i have a parser for start parsing and for start element
when im doing this i get the complete xml parsed after the xml is parsed how do i get it i still could not get how to soak the characters .....
private void startParsing()
          try
               InputStream instream = getClass().getClassLoader().getResourceAsStream(contextFile);
               InputSource in = new InputSource(instream);
               SAXParser parser = SAXParserFactory.newInstance().newSAXParser();
               XMLReader reader = parser.getXMLReader();
               reader.setContentHandler(this);
               reader.parse(in);
          catch(ParserConfigurationException pce)
               System.out.println(pce);
          catch(SAXException se)
               System.out.println(se);
          catch(IOException ie)
               System.out.println(ie);
     public void startElement(String uri,String localName,String qName,Attributes attributes)
          System.out.format("uri : %s localName %s qName %s %n",uri,localName,qName);
so now i have an attribut but i need content of the opening and closingtag like
attribute is name
<name>jack</name>
im successfull in getting name but now i want jill ....

How to Feed HTTP POST reply to a SAX Parser?

Hello
I want to make a POST, the body of the reply is an xml document I want to parse it with help of a SAX parser (responseHandler object here). I have not been able to setup a test environment and I have limited time so I wanted to check with you if you have any remarks on my code, or if you better solution. I have done the following
URL url = new URL("http://myserver.com:8888");
            connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("POST");
            connection.setAllowUserInteraction(false);
            connection.setDoOutput(true);
            connection.setRequestProperty("Content-type",
                    "application/x-www-form-urlencoded");
            connection.setRequestProperty("Content-length", Integer
                    .toString(content.length()));
        OutputStream ost = connection.getOutputStream();
        PrintWriter pw = new PrintWriter(ost);
        pw.print(content);// send
        pw.flush();
       httpReply = connection.getResponseCode();
            // could not contact server
            if (httpReply != HttpURLConnection.HTTP_OK) {
                // TODO Check for thread safety
                alarmHandler.raiseServerNotAvailableAlarm();
                result = new String[0];
                return result;
                // Contacted Server
               // now parse the reply
            } else {
                alarmHandler.clearServerNotAvailableAlarm();
                SAXParserFactory spf = SAXParserFactory.newInstance();
                SAXParser parser = spf.newSAXParser();
                parser.parse(connection.getInputStream(), responseHandler);
                return (String[]) responseHandler.getRejectedMSISDNs().toArray();
