SOAP vs other xml parsers

Hi,
I'm fairly new to jms and was wondering what are the advantages of using SOAP vs any xml parser (xerces, jaxb) and sending it as a regular text message?
Thanks

SOAP isn't just 'another XML parser', it's a fully fledged RPC protocol with an interface description language and all the rest of it.

Why other xml parsers won' work?

i hav a reqm't of loading java classes into the d'base and one of those classes uses xslt processor to convert a xml to html the xsl is embedded as a string in the java code itself, i create a jar file with apache xalan parser and load it into d'base but at runtime i'm getting
"String Index out of Bounds exception"
so i changed the parser to oracle xsl parser now it works fine why is it so?
our entire development team uses the xalan parser for various purposes so i can' use oracle parser for this purpose alone as it makes the system inconsistent.
will anyone from oracle come forward to provide a solution.
thanks

This is not a Xalan issue, but a Xerces issue. When Xerces is installed inside Oracle8i, it runs into a bug in the VM related to System.arrayCopy() for multi-dimensional arrays of scalars.
The bug has been fixed in 8.1.7, so it should work fine there.
I guess our XML components don't ever do array copies of multi-dimensional arrays, so they don't run into the bug.

Julio,
Are you sure that XML is correct?
No data allowed here: (hex) 6e, 74, 6f(:main:, row:1, col:3)
I also see Parse exceptions at different lines?
check the NOTE : 931765 @
https://websmp130.sap-ag.de/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/sapnotes/index2.htm?numm=931765
Check if the incoming XML has style informaton associated with it. Refer to following link for more info.
http://schemas.xmlsoap.org/soap/envelope/
If the problem still persists, Restart J2EE Instance.
Regards,
Venkat.

Package javax.xml.parsers does not exist

When I compile the sample program for xml, DOMEcho.java, or any other xml java program, I get errors on the import statements.
For all the import statements within java.xml.* I get an error message such as: package javax.xml.parsers does not exist.
I have my path and classpath variables set as follows.

Version 2.0 is the latest release that is bundled with Oracle8i. Use the 2.0 releases as their functionality and performance is much better.

Experiences with Adobe XPAAJ, XML Parsers, OC4J /AS 10.1.2,10.1.3 and DB10g

Over the past couple of weeks we have been working on a solution which uses the newly available adobe XPAAJ api's (XML/PDF Access API for Java) for Java.
The client has a legacy requirement to where users are issued with a pdf form which they complete, save and upload to the server via a JSP. A neat bit of Java code utilizing the XPAAJ API's then strips out the form entered data and spits out XML. This is then parsed and inserted into relational tables within the schema.
Our solution needs to be deployed to an Oracle stack. However we ran into a number of problems when deploying the solution to AS 10.1.2. The adobe API's are not compatible with the Oracle XML Parsers. When extracting the form data, no error is reported and the code which performs the xml parsing just fails. Very nasty.
The main problem has been that Oracle XDK libraries have been hard-coded into the classpath of the container using the referential JAR file Class-Path mechanism. Altering this has required the use of the JRE extension library mechanism, or altering the boot classpath of the JVM when it is launched to load the alternative XML parser implementation instead. While this works, it has been an unsupported operation since the effect of this change is not limited to a specific application – it’s effect are felt across the entire container and this may lead to unpredictable results at runtime.
~http://www.oracle.com/technology/tech/java/oc4j/10131/how_to/how-to-swapxmlparser/doc/readme.html
We did look at a number of other solutions including embedding the java classes I'd written into the database. After loading the apache Xerces api's into our schema we hit upon the same problem. It seems that the same thing happens in the database and the Oracle XML parser is used by default.. Please see SR Number : 6153038.994 on Metalink.
If you can upgrade to AS 10.1.3 then you can follow the excellent how to at:http://www.oracle.com/technology/tech/java/oc4j/10131/how_to/how-to-swapxmlparser/doc/readme.html . Demo code can be found at: http://www.oracle.com/technology/tech/java/oc4j/10131/how_to/how-to-swapxmlparser/how-to-swapxmlparser.zip
The how-to details how to swap xml parsers within the application server.
Other possible solutions that are also available include:
- Shelling out to the OS from the DB or Apps Server, You can then execute the app as a command line app with a custom classpath. Very bad architecture design.
- Setting up an RMI client / server application where client is the db or apps server. You can find examples of this on the web. google 'Simple RMI example'.
- Bootstrapping the XML parser in AS 10.1.2 (unsupported).
I hope people have found this informative. It might save someone a lot of time.

so you talk about the db version. SOA 10.1.3.x runs on 10.2.0.1 and above (I ran for the longest time on XE) and if I remember correctly that's a warning, and not a hard prereq.
Regarding Appserver versions - soa 10.1.3 runs on AS 10.1.3 only

Weblogic 12g Server - EAR with WAR - how can I have different XML parsers

Hi All,
I have a requirement where I need to have two different XML parsers in the same enterprise application.
By backend Spring container require a XML parser and my JSP code which has XSLT logic require another XML parser.
If I specify -D System property then it is applied to the whole Enterprise application. Instead I want a way to specify different XML parsers one for Spring backend container and the other for JSP pages.
I am deploying my application in Weblogic and it is an EAR file.
Thanks in Advance,

How to test SOAP request using XML SPY

Hi,
1. I am new to WebServices concept, I have downloaded the wsdl file and now I need to test the SOAP requests using XML Spy. However, when I try to test the SOAP request generated by XML Spy I receive an error "Internal Error: Session is not available. Aborting" , How do I go ahead to generate the session, Is there a way I can provide the Username and password in the XML Spy to generate something like session.
2. The second problem that I am facing is when I import the WSDL in XML Spy and generate the SOAP request, for all the fields xml tags gets populated with "aaaaaaaaaaaa" kind of data through out. Am i doing something wrong ? Is there some step while creating a SOAP request that I am missing becasue of which the gibbrish data is being populated as default ?
Please Help !
Thanks .

I got my SOAP Requests tested using SOAP UI .. However I am still looking for ways to test it using XML SPY.
In the SOAP UI Tool just do right click and select Add WS Security Token ..
Thanks :)

Is there a package that a have to add to the environment? Can some one tell my where i can find this package?
I wrote the code for some years ago, 2006 or so. With the knew jdk1.6.0_13 some thinks chance in the environment. Couldn't find what exactly.
The code has only 215 lines, but some how i can't add it to this Message, because Maximum allowed is only 7500.

Java XML parsers for Sun J2ME, Sun KVM

Here is a list of "small" XML parsers.
Some are specifically for the J2ME platform / Sun KVM:
kXML
http://kxml.enhydra.org/
NanoXML
http://nanoxml.sourceforge.net/
TinyXML
http://www.gibaradunn.srac.org/tiny/index.shtml
MinML
http://www.wilson.co.uk/xml/minml.htm
XMLtp
http://sourceforge.net/projects/jxmltp/
Al Sutton XML parser
http://sourceforge.net/projects/asxmlp/
Also:
JSR 118 is a specification for the "Mobile Information Device
Next Generation"
http://www.jcp.org/jsr/detail/118.jsp
The JSR 118 group is considering adding a "small, efficient XML parser to enable platform-independent data exchange" to MIDP.

Fastparser is a 25Ko parser : http://www.japisoft.com/fastparser

What is payload, xi-soap message and xml payload....

can any 1 explains abt What is payload, xi-soap message and xml payload....

Hi Shiva,
see this abstract from messages file:
"The SOAP header of a message contains all the important information that the Integration Server requires to forward the message, while the payload contains the actual business data (such as <PurchaseOrder> in the example above). You can also append an unlimited number of attachments to the message before it is sent. Attachments typically comprise non-XML data, for example, pictures, text documents, or binary data."

XML parsers in JAVA

Hi all,
I need to parse XML files in JAVA. Is there any specific package in java for XML parsing?

Example for using DOM :
import java.io.File;
import javax.xml.parsers.*;
import org.w3c.dom.*;
// using DOM
public class ParseXML_Dom {
 public static void main(String[] args) {
 File file = new File("test.xml");
 try {
 DocumentBuilder builder =
 DocumentBuilderFactory.newInstance().newDocumentBuilder();
 Document doc = builder.parse(file);
 NodeList nodes = doc.getElementsByTagName("topic");
 for (int i = 0; i < nodes.getLength(); i++) {
 Element element = (Element) nodes.item(i);
 NodeList title = element.getElementsByTagName("title");
 Element line = (Element) title.item(0);
 System.out.println("Title: " + getCharacterDataFromElement(line));
 NodeList url = element.getElementsByTagName("url");
 line = (Element) url.item(0);
 System.out.println("Url: " + getCharacterDataFromElement(line));
 } catch (Exception e) {
 e.printStackTrace();
 The file "text.xml" might contain this :
<?xml version="1.0"?>

 public static String getCharacterDataFromElement(Element e) {
 Node child = e.getFirstChild();
 if (child instanceof CharacterData) {
 CharacterData cd = (CharacterData) child;
 return cd.getData();
 return "?";
}
