Java Http Listener to parse incoming XML
Hey folks,
I have a task where I need to create a secure http listener, which will then parse an incoming XML. Parsing an XML document seems pretty straight forward so no problems there.
basically what I would like to know is how would I get started? Would I use a servlet? Im not familiar enough with the capabilities of Java to know what packages to use and whatnot. How would some of you go about designing such a system?
Thanks in advance,
Ken
Yes, you can write a Servlet which does that.

Parsing an XML using DOM parser in Java in Recursive fashion
I need to parse an XML using DOM parser in Java. New tags can be added to the XML in future. Code should be written in such a way that even with new tags added there should not be any code change. I felt that parsing the XML recursively can solve this problem. Can any one please share sample Java code that parses XML recursively. Thanks in Advance.
Actually, if you are planning to use DOM then you will be doing that task after you parse the data. But anyway, have you read any tutorials or books about how to process XML in Java? If not, my suggestion would be to start by doing that. You cannot learn that by fishing on forums. Try this one for example:

PLEASE : JAVA PARSER SCHEMA XML doesn't work
Hi,
I search how can I parse a xml document with schema, which works with Sun'SAX in JAVA.
I have no real idea to it, but I think that JAXP can work (is it a good idea?)
I have found this exemple :
http://dataml.net/articles/ValidateXMLSchema/part1.htm
This example is often posted in the forum, but for me it doesn't work, and you? have you had a probleme with it?
Have you others examples which work or tutorials for parse xml with schema with SAX in java?
Furthermore what are the specifics recommandations to install JAXP ?
Thanks a lots.Nobody can help me?
please -
Java stored proc performance parsing XML docs
Hi
We are using ORACLE 8i(8.1.6). I have a JAVA Stored procedure that parses XML doc and returns tha values. If I am testing on the box, I get an avg. return time of 2 secs. If I have 20 users, my return time for all went to 25 to 35 secs?
Are there any parameters on ORACLE I can modify to increase the performance. We are developing app for 1000 to 1500 users. I dont want to guess the time based on my test with 20 users.
Any help will be greatly appreciated.
Thank You
RajuRaju,
Oracle 8.1.7 should be better choice for you since it does have the XML stuff
natively compiled.
Regarding scaleability the JVM should scale
very well. However let us know what you find.

How to parse whole xml elements into a java String
hello everybody,
I am trying to parse whole xml into a string for example
my xml file is as below:
<root>
<element>
<data id="1">1</data>
</element>
<element>
<data id="2">2</data>
</element>
</root>
in java whole data should be transfered as
String xmlString ="<root><element><data id=\"1\">1</data></element><element><data id=\"2\">2</data></element></root>";or in a simple way can xml be copied into a string? any assistance ...
thanQ in Advance.
Han.This code is to convert xml document to a string.
try {
javax.xml.transform.TransformerFactory tfactory = TransformerFactory.newInstance();
javax.xml.transform.Transformer xform = tfactory.newTransformer();
javax.xml.transform.Source src = new DOMSource(xmlString);
java.io.StringWriter writer = new StringWriter();
StreamResult result = new javax.xml.transform.stream.StreamResult(writer);
xform.transform(src, result);
//System.out.println(writer.toString());
} catch (TransformerConfigurationException e) {
e.printStackTrace();
}catch(Exception ex )
ex.printStackTrace();

If anyone could at least guide me with the basic commands and structure of the parser it would be really really great ...
Thanks a lot
AnishaNormally if you have no idea about X, the first thing you should do is google "X tutorial". You will find plenty of them out there. And the advantage is, they are better written than whatever we spend two minutes throwing together here. Not to mention that it saves us the two minutes.
But if you have specific questions with your SAX parser when you get it going, then ask them here. Actually, ask them in the XML forum here, not this one. -
Ignore DTD declaration in incoming XML message
Hi,
I have an issue where I am receiving an incoming XML message which starts with a DTD declaration.
This causes an issue with the XML parser step in the mapping because the parser attempts to resolve the DTD location. However this location is external and the PI server cannot access it.
The location for reference is http://dtd.bibit.com/paymentService_v1.dtd
Therefore I am investigating options to ignore the DTD declaration or removing it altogether prior to the XML parser step.
I would hope I could use either XSLT or Java mapping but do not really know where to start.
Can anyone please provide a method of doing this ? I would prefer to use XSLT but am open to other options.
I have no control over the DTD declaration as it is supplied by a 3rd party application.
Thanks
Colin.Hi Russell,
The XSLT sample you have provided does not work.

I didn't find a method that parses a XML document when it's not a file. I have a String that I want to parse and the method DocumentBuilder.parse only accepts a String that is a uri to a file.
I write this code:
String strXML = "<?xml version='1.0' ?><root><node>anything</node></root>";
DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
domDoc = docBuilder.parse(strXML);
Please gimme a light!!

Charset conversion of incoming XML documents
XML documents may contain data in other charsets than SAP's UTF-8. I'm using the ixml lib in ABAP. Using 'get_encoding', I can determine the incoming document's charset, but it seems only after having parsed it. I'd like to convert the entire document to the current SAP charset before processing. I didn't find a way in the ixml methods to do this, so I imagine I'll have to use CL_ABAP_CONV_IN_CE somehow.
What's the best way to handle non-SAP charsets in incoming XML documents?ha that was just a joke. check the link below

Can someone help me with a problem of parsing an XML file?
Hello,
I'm having some problems parsing an xml file. I get a SAXNotSupportedException when setting a property value.
Here is the piece of code where I have the problem:
SAXParserFactory spf = SAXParserFactory.newInstance();
spf.setNamespaceAware(true);
SAXParser saxParser = spf.newSAXParser();
XMLReader xmlReader = saxParser.getXMLReader();
DefaultHandler defHandler = new DefaultHandler();
xmlReader.setProperty("http://xml.org/sax/properties/lexical-handler", defHandler);
and the log is:
Problem with the parser org.xml.sax.SAXNotSupportedException: PAR012 For propertyID "http://xml.org/sax/properties/lexical-handler", the value "org.xml.sax.helpers.DefaultHandler@4ff4f74a" cannot be cast to LexicalHandler.
http://xml.org/sax/properties/lexical-handler org.xml.sax.helpers.DefaultHandler@4ff4f74a LexicalHandler
I've been working on this problem but I can't find the error.
Does anyone have an idea of what to do to solve it?
Thanx in advance,
M@Gbefore deciding which XML technology to use, you should see if your application fit in the category below:
use SAX:
1. The XML file is rather large (30 or 40+ MB)
2. I don't need the xml document in memory. I will parse the document and store the data in my own object.
use DOM or JDOM
1. The XML file is relatively small (less than 30 MB) or I can increase the runtime memory for larger xml file.
2. I will need to walk up and down the xml document tree severals time.
3. My application is in Java and it's not going to be rewritten in C++, etc (use JDOM)
NOTE:
JDOM is rather easier to use (for Java developer), but it's not an www.org.com standardlized xml parser.
personally, i like JDOM for traversing the DOM. -
Parsing an XML doc with unavailable entity (DTD)
Hi all,
I am trying to parse an XML file (web.xml) that has the following DOCTYPE in the head of the document:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app id="WebApp">When the parser starts, it will look for the DTD on the Sun site, however my work firewall blocks access to this so I get an exception when parsing.
To resolve this, I have tried to force the parser to look for a local copy of the DTD instead of the Sun site but to no avail. I still get the same error but don't know why it wont look at the local DTD.

RizWhat's the point of all that code in your EntityResolver? Would the code work just as well if the DTD didn't even exist? Then do this:public InputSource resolveEntity(String publicId, String systemId)
return new InputSource(new StringReader(""));
}However if you really do need to redirect to a local copy of the DTD then consider this:catch (IOException e) { }can be a real barrier to understanding in the case that an IOException is thrown. At least print a stacktrace. And: the FileReader class wants a file name in its constructor, not a URI. And in this code:String filename = uri.getSchemeSpecificPart();
filename = "file:/C:/web-app_2_3.dtd";you could write this instead:String filename = "file:/C:/web-app_2_3.dtd";which would be both shorter and easier to understand. -

I am trying to parse a xml file using a jdom java code.This code works fine if I remove xmlns attribute in the root element. (I get the expected result) .If the "xmlns" attribute is put in the xml as it should be then the parsing and retrieving returns null. Please tell me how to fix this issue.

Xml
<process name="CreateKBEntryService" targetNamespace="http://serena.com/CreateKBEntryService" suppressJoinFailure="yes" xmlns:tns="http://serena.com/CreateKBEntryService" xmlns="http://schemas.xmlsoap.org/ws/2003/03/business-process/" xmlns:bpelx="http://schemas.oracle.com/bpel/extension" xmlns:ora="http://schemas.oracle.com/xpath/extension" xmlns:nsxml0="http://localhost:8080/axis/services/CreateKBEntryService" xmlns:nsxml1="http://DefaultNamespace" xmlns:bpws="http://schemas.xmlsoap.org/ws/2003/03/business-process/">

<partnerLink name="client" partnerLinkType="tns:CreateKBEntryService" myRole="CreateKBEntryServiceProvider"/>
<partnerLink name="CreateKBEntryPartnerLink" partnerLinkType="nsxml0:CreateKBEntryLink" partnerRole="CreateKBEntryProvider"/>

Java:
import java.io.*;
import java.util.*;
import org.jdom.Document;
import org.jdom.Element;
import org.jdom.input.SAXBuilder;
public class sample1 {
public static void main(String[] args) throws Exception {
// create a XML parser and read the XML file
SAXBuilder oBuilder = new SAXBuilder();
Document oDoc = oBuilder.build(new File("**xml file location**"));
Element root = oDoc.getRootElement();
System.out.println(root.getName());
String tgtns= root.getAttributeValue("targetNamespace");
System.out.println("tgt ns "+ tgtns);
List list= root.getChildren("partnerLinks");
Iterator it1= list.iterator();
System.out.println("Iterator 1 - "+list.size());
while(it1.hasNext()){
Element partnerlinks = (Element)it1.next();
List list2= partnerlinks.getChildren("partnerLink");
System.out.println("iterator 2 - "+list2.size());
}~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Result:
Without Xmlns in xml file(Expected and correct output)
process
tgt ns http://serena.com/CreateKBEntryService
Iterator 1 - 1//expected and correct result that comes when I remove xmlns attribute from xml
iterator 2 - 2
Result with xmlns:
process
tgt ns http://serena.com/CreateKBEntryService
Iterator 1 - 0 //instead of 0 should return 1LOL
This is what you get for working 12 hours straight....
I changed:
xmlObject["mydoc"]["modelglue"]["event-handlers"]["event-handler"][i].xmlAttrib utes["name"]<br>
to:
#mydoc["modelglue"]["event-handlers"]["event-handler"][i].xmlAttrib utes["name"]#<br>
xmlObject is the name of my xml object in memory, and then you reference from the root of the xml doc down the chain.
Sorry for the inconvenience,
Rich
