SAX help
Hi all
I want to know how to get index of attribute with SAX using javax.xml.parsers.SAXParser ,but when i use Attributes getIndex(QualifiedName); method it returns -1 but a single attribute is present in XML File ,so i wana know why it happens?
thanks in advance
hi
try this.i dont know whether this is wht u meant.
public void startElement(String qname,Attribute attr)throws SAXException
for(int i=0; i<attr.getLength();i++)
System.out.println(attr.getIndex(attr.getQName(index)));
}

Hi,
Why am i not getting the localName in the endElement() when i use this class DefaultHandler
The syntax says ,
localName - The local name (without prefix), or the empty string if Namespace processing is not being performed.
So how should i perform "Namespace processing"
anyone know this ?
-localName - The local name (without prefix), or the empty string if Namespace processing is not being performed.Most SAX parsers perform namespace processing on namespace qualifed elements by default, with an option to turn it off.
The XML document you are parsing may or may not be using namespaces.
If it does use namespaces, then the local name will be the local name of an element whose tag name is in a namespace. If the element's tag name is not in a namespace, then the local name may be empty. Whether or not is a parser implementation variation point.
Use the qName to get a non-namespaced element's tag name.
Some discussion as to whether SAX implementations follow the spirit of the XML namespaces spec. can be found here: http://lists.xml.org/archives/xml-dev/200205/msg01378.html

Hi Team,
I have an OEP running with Oracle DB but I need to move to MySQL.
Has anyone done this?
What is required?
ThanksHere are the steps which should be used:
1. Created a bundle jar for mysql driver(followed steps as per the OEP documentation )
Goto $ORACLE_HOME/oep/bin in server installation directory
Run the following script
sh bundler.sh -source /scratch/sbishnoi/view_storage/sbishnoi_india/cep/wlevs_cql/release/target/server/oep/bin/mysql-connector-java-commercial-5.1.34-bin.jar -name mysql5 -version 5.1.34 -factory com.mysql.jdbc.jdbc2.optional.MysqlXADataSource com.mysql.jdbc.Driver -service javax.sql.XADataSource java.sql.Driver -targetdir .
The generated jar will be in the current directory and its name will be mysql5_5.1.34.jar.
Please note that the connector jar mysql-connector-java-commercial-5.1.34-bin.jar was part of MySQL Server installation and wasn't download it separately.
2. Manually edit the MANIFEST.MF of newly generated jar mysql5_5.1.34.jar to remove unwanted imports which may cause you to download dependencies.
The import section for my jar looks like as follows:
Import-Package: javax.crypto,javax.xml.stream,javax.sql,javax.naming,javax.xml.transform.dom,javax.naming.spi,org.xml.sax,org.xml.sax.help
ers,org.w3c.dom,javax.xml.transform.sax,javax.transaction.xa,javax.management,javax.xml.transform.stax,javax.xml.parsers,javax.xml.transfo
rm,org.osgi.framework,javax.xml.transform.stream,javax.xml.datatype,javax.net.ssl,javax.net
3. Copy the driver bundle jar into following server directory inside domain directory:
$ cp mysql5_5.1.34.jar …….user_projects/test_domain/defaultserver/modules/ext/
Create modules/ext directories if it doesn’t exist and then copy the jar.
4. Prior to starting server, Edit the server’s configuration to define the datasource.
Here is config.xml file which we tried:
<data-source>
<name>mysql</name>
<data-source-params>
<global-transactions-protocol>None</global-transactions-protocol>
</data-source-params>
<connection-pool-params>
<test-table-name>SELECT 1 FROM DUAL</test-table-name>
<initial-capacity>5</initial-capacity>
<max-capacity>10</max-capacity>
</connection-pool-params>
<driver-params>
<url>jdbc:mysql://10.159.165.60/mysql</url>
<driver-name>com.mysql.jdbc.Driver</driver-name>
<properties>
<element><name>user</name><value>mysql</value></element>
<element><name>password</name><value>mysql</value></element>
<element><name>com.bea.core.datasource.serviceName</name><value>mysql5</value></element>
<element><name>com.bea.core.datasource.serviceVersion</name><value>5.1.34</value></element>
<element><name>com.bea.core.datasource.serviceObjectClass</name><value>javax.sql.XADataSource</value></element>
</properties>
<use-xa-data-source-interface>false</use-xa-data-source-interface>
</driver-params>
</data-source>
5. Now Start the server. Make sure MySQL Database is running on the URL mentioned in config file.
Although on server startup, you will see the following exception(not to worry about):
[sbishnoi@adc2101019 defaultserver]$ sh startwlevs.sh

These are related to some configuration test query execution on database to ensure connectivity. The exception here is SQL syntax which is not a connectivity issue so we can safely assume that connection is obtained. -
Can someone say how to initialize a SAX parser?
When I try to do it, a SAXException occures.
I think thats because no paser driver is loaded (as API docs say).
How can I make it work?Try the following snippet (not compiled) with JDK 1.3 or higher (crimson included) to get the idea:
class DummyContentHandler implements org.xml.sax.ContentHandler{
int count = 0;
public void startDocument() throws org.xml.sax.SAXException {}

public void startPrefixMapping(java.lang.String str, java.lang.String str1) throws org.xml.sax.SAXException {}

SAX error parsing by element. need help!
I am trying to develop a small method to that can parse an xml file and return an elements value. I got some code to build a SAXHandler. I have build the SAXHandler and have compiled it no problem.
import java.io.*;
import java.util.Hashtable;
import org.xml.sax.*;
import org.xml.sax.helpers.*;
public class SAXHandler extends DefaultHandler {
private Hashtable table = new Hashtable();
private String currentElement = null;
private String currentValue = null;
public void setTable(Hashtable table) {
this.table = table;
public Hashtable getTable(){
return table;
public void startElement(String tag, Attributes attrs)
throws SAXException {
currentElement = tag;
public void characters(char[] ch, int start, int length)
throws SAXException {
currentValue = new String(ch, start, length);
public void endElement(String name) throws SAXException {
if (currentElement.equals(name)) {
table.put(currentElement, currentValue);
I am using the following code to read the file in and parse it.
public String getXMLElement(){
try {
File xmlFile = new File(appDataFile);
FileReader xmlRead = new FileReader(xmlFile);
XMLReader xmlParser;
SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();
SAXHandler handler = new SAXHandler();
sp.parse(new InputSource(xmlRead), handler);
i am recieving the following error when I try to run the servlet
javax.servlet.ServletException: Cannot allocate servlet instance for path /JDtrack/servlet/JDTrack
what makes this wierd is that is i take out the line
sp.parse(new InputSource(xmlRead), handler);
I do not get the error.
I am newer to java and could use all the help I can get
thanks.A few things to try to help identify the problem:
-Create and InputSource before parsing the file. If the InputSource cannot be created, there may be a problem with accessing the file from your servlet.
-Write a quick program to do the same thing from an application. If you can do this outside the servlet container, it may be a problem from running inside the servlet container.
-The code you listed is in a try block, however the catch block is not listed. If you are not already doing so, place debug message (to console or log) from inside each catch block. If an exception is thrown but not handled corrrectly, the servlet container may just throw a ServletException.
Hope this helps. -

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. -

Geetanjali P.Parsers are for inputting XML data. Your question is about outputting XML data, so your choice of parser is irrelevant. What is relevant is how you are outputting your XML, and you didn't say anything about that. So please do.

I need to write a program that converts XML documents into HTML documents using SAX. I've never used SAX before and am not that familiar with XML. I went over a tutorial ( http://java.sun.com/webservices/jaxp/dist/1.1/docs/tutorial/sax/index.html ) yet am still completely lost regarding what I should be doing. Would anyone give me some foundation on what I need or where I should look or what I should be doing? I just need help.
It is all in that tutorial. So if you don't understand it, read it again. Fiddle around with the code there and see what it does. And also, try to get the "using SAX" requirement removed and see if "using XSLT" is any easier.

Hi guys,
i got the following xml :
<root>
<applications>
<application id="CUP">
<area id="folders">
<area id="foi1">
<param id="pam1">C:\app\yak1</param>
<param id="pam2">1</param>
<param id="pam3">2</param>
</area>
<area id="foi2">
<param id="pam1">C:\app\yak2</param>
<param id="pam2">2</param>
<param id="pam3">1</param>
</area>
</area>
<area id="dao-group-mapping">
<param id="US">C:\app\yak1\myapp1.txt,C:\app\yak1\myapp2.txt</param>
<param id="UK">C:\app\yak1\myapp3.txt</param>
<param id="CN">C:\app\yak1\myapp4.txt</param>
</area>
</application>
</applications>
</root>
and code below:
public class CupConfigParserHandler extends DefaultHandler {
private Map<String, FolderInfo> folderInfoMap;
private Map<String, ArrayList> daoMappingMap;
public static void main(String[] args) {
CupConfigParserHandler cupConfigParserHandler = new CupConfigParserHandler ();
cupConfigParserHandler
.parseDocument("c:/eclipse/cup/cup-config.xml");
public CupConfigParserHandler(String filePath) {
folderInfoMap = new HashMap();
folderInfoMap = new HashMap();
try {
init(filePath);
} catch (Exception e) {
e.printStackTrace();
private void init(String filePath) throws IOException, SAXException {
// Use the default (non-validating) parser
SAXParserFactory factory = SAXParserFactory.newInstance();
try {
// Parse the input
SAXParser saxParser = factory.newSAXParser();
saxParser.parse(new File(filePath), this);
} catch (Throwable t) {
t.printStackTrace();
private void parseDocument(String filePath) {
// get a factory
SAXParserFactory spf = SAXParserFactory.newInstance();
try {
// get a new instance of parser
SAXParser sp = spf.newSAXParser();
// parse the file and also register this class for call backs
sp.parse(filePath, this);
} catch (SAXException se) {
se.printStackTrace();
} catch (ParserConfigurationException pce) {
pce.printStackTrace();
} catch (IOException ie) {
ie.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
public void startElement(String ns, String ln, String qname, Attributes atts)
throws SAXException {
public void characters(char[] ch, int offset, int length)
throws SAXException {
public void endElement(String ns, String ln, String qname)
throws SAXException {
I am not sure how to fill up the startElement and endElement methods. I just need to fill up the folderInfoMap and daoMappingMap. Those area element under "folders" area element will grow in future. So how do I like once the program detected area element with id = "folders", it will put everything under "folders" elements into a map. I can't use any open source. Please help. Thanks !
GainsHi
Plesae follow this link for an example of JAVA mapping using SAX parser

Help setting up Aelfred and SAX for MIDP
This relates to chapter 11 & 12 of Yu Feng book Wireless Java Programming with J2Me.
Where exactly do you install Aelfred and Sax? What variables have to be set in the class path or what jar files have to be placed where.
I can't compile my application because the class files that come with Aelfred can't find java.io.*; from the import Statement in the class file.
The above class file is located in the4 SRC directory of my application.I've just realised that you have to manually remove some stuff from the classes such as reference to J2Se classes.
How do you do this. -
Javadoc for the SAX 1.0 API states its should be possible to reuse a parser object to parse one document after another. I have not been able to do this - I keep getting and error "EOF expected" even though endDocument() in HandlerBase has been called.
Is this a bug?

Sorry - this isn't quite right. The final tag is parsed, but endDocument is never called. How can I get that event to be thrown without closing the stream feeding the inputSource? -
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 helphi 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
