Query on XML Beans replacing Castor Java -XML Bindings

Hello,
We use Castor XML Framework for today Java - XML bindings and were looking for XML Beans replacement.
One of the key problems we face in using XML (maybe a flawed design) is we create XSD for our applications and run Castor to generate Java Classes as Libraries (XMLFramework.jar).
Applications are compiled with these Java libraries and Castor is used to Marshal the Java Object as XML Document when invoking a remote API and at the receiving side it is used to unmarshal back the XML document to Java Object.
Major issues we have seen is that if any XSD (that defines application ICD) changes, we need to re-generate Castor Java classes (new XMLFramework.jar) and re-compile applications that were using these classes with new JAR files..... Thus for small XSD changes the impact is in lot of applications (where an application is an EAR deployed on WLS)
Does XMLBeans help here that I can change XSD without changing all the end-points that use Classes generated out of these XSDs (when additing mandatory or optinal elements) ?
Or there is a flaw in which we have used the Java-XML binding framework like Castor and XMLBeans do not help much ?

Can someone please suggest on how I can go about
converting an XML file into word format using Java
?How about POI?

XML Beans in Web Services / .xsd compilation

Hello friends -
I've been told of many wonderful things that can be accomplished by using XML
beans in web service style integrations. However, I'm running into trouble actually
getting anything done and was hoping someone could give me a few pointers. I'm
trying to work inside Workshop 8.1 with the BEA server (i.e., not platform)
- Documentation seems to reference the ability to compile an .xsd in order to
get an XML Bean class representing your XML. However, I cannot find anything
telling me how to do this. Is this supported in Workshop?
- I'm only showing some classes referenced in the XML Beans Javadoc area as available
inside my workshop IDE. For example, com.bea.xml.XmlBeans is not available.
Is this a result of me using Server as opposed to the more complete Platform
product?
- Does anyone have a simple example .jws that utilizes a XML bean as an input
or output? If so, I'd love to see it.
Thanks so much.

Hi,
I thought passing XMLs was supported using SOAP. In this case, the XML data in the SOAP body is type "string" and the namespace of the XML inside separates it from the rest of the SOAP package. Can I do the same with...say... Web Dynpro where the WSDL is used to generate proxy classes. How do I add a namespace in the SOAP header so that I can add the XML in the body?
I propose that life would be much easier if a datatype called XML, or some option before the WSDL is imported to create proxy classes is available which creates a wrapper for adding XML data. Far fetched...but can be done. Whats you opinion?

How to get an XML string from a Java Bean without wrting to a file first ?

I know we can save a Java Bean to an XML file with XMLEncoder and then read it back with XMLDecoder.
But how can I get an XML string of a Java Bean without writing to a file first ?
For instance :
My_Class A_Class = new My_Class("a",1,2,"Z", ...);
String XML_String_Of_The_Class = an XML representation of A_Class ?
Of course I can save it to a file with XMLEncoder, and read it in using XMLDecoder, then delete the file, I wonder if it is possible to skip all that and get the XML string directly ?

I think so too, but I am trying to send the object to a servlet as shown below, since I don't know how to send an object to a servlet, I can only turn it into a string and reconstruct it back to an object on the server side after receiving it :
import java.io.*;
import java.net.*;
import java.util.*;
class Servlet_Message        // Send a message to an HTTP servlet. The protocol is a GET or POST request with a URLEncoded string holding the arguments sent as name=value pairs.
public static int GET=0;
public static int POST=1;
private URL servlet;
// the URL of the servlet to send messages to
public Servlet_Message(URL servlet) { this.servlet=servlet; }
public String sendMessage(Properties args) throws IOException { return sendMessage(args,POST); }
// Send the request. Return the input stream with the response if the request succeeds.
// @param args the arguments to send to the servlet
// @param method GET or POST
// @exception IOException if error sending request
// @return the response from the servlet to this message
public String sendMessage(Properties args,int method) throws IOException
    String Input_Line;
    StringBuffer Result_Buf=new StringBuffer();
    // Set this up any way you want -- POST can be used for all calls, but request headers
    // cannot be set in JDK 1.0.2 so the query string still must be used to pass arguments.
    if (method==GET)
      URL url=new URL(servlet.toExternalForm()+"?"+toEncodedString(args));
      BufferedReader in=new BufferedReader(new InputStreamReader(url.openStream()));
      while ((Input_Line=in.readLine()) != null) Result_Buf.append(Input_Line+"\n");
    else
      URLConnection conn=servlet.openConnection();
      conn.setDoInput(true);
      conn.setDoOutput(true);
      conn.setUseCaches(false);
      // Work around a Netscape bug
      conn.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
      // POST the request data (html form encoded)
      DataOutputStream out=new DataOutputStream(conn.getOutputStream());
      if (args!=null && args.size()>0)
        out.writeBytes(toEncodedString(args));
//        System.out.println("ServletMessage args: "+args);
//        System.out.println("ServletMessage toEncString args: "+toEncodedString(args));
      BufferedReader in=new BufferedReader(new InputStreamReader(conn.getInputStream()));
      while ((Input_Line=in.readLine()) != null) Result_Buf.append(Input_Line+"\n");
      out.flush();
      out.close(); // ESSENTIAL for this to work!
    return Result_Buf.toString();               // Read the POST response data
// Encode the arguments in the property set as a URL-encoded string. Multiple name=value pairs are separated by ampersands.
// @return the URLEncoded string with name=value pairs
public String toEncodedString(Properties args)
    StringBuffer sb=new StringBuffer();
    if (args!=null)
      String sep="";
      Enumeration names=args.propertyNames();
      while (names.hasMoreElements())
        String name=(String)names.nextElement();
        try { sb.append(sep+URLEncoder.encode(name,"UTF-8")+"="+URLEncoder.encode(args.getProperty(name),"UTF-8")); }
//        try { sb.append(sep+URLEncoder.encode(name,"UTF-16")+"="+URLEncoder.encode(args.getProperty(name),"UTF-16")); }
        catch (UnsupportedEncodingException e) { System.out.println(e); }
        sep="&";
    return sb.toString();
}As shown above the servlet need to encode a string.
Now my question becomes :
<1> Is it possible to send an object to a servlet, if so how ? And at the receiving end how to get it back to an object ?
<2> If it can't be done, how can I be sure to encode the string in the right format to send it over to the servlet ?

Using XPath to locate the elements you are after is very easy.
Try something like this:
import java.io.File;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;
import javax.xml.xpath.XPath;
import javax.xml.xpath.XPathConstants;
import javax.xml.xpath.XPathFactory;
import org.w3c.dom.Document;
import org.w3c.dom.NodeList;
import org.xml.sax.InputSource;
public class BasicXMLReplaceWithDOM4J {
     static String inputFile = "C:/student.xml";
     static String outputFile = "C:/studentRenamed.xml";
     public static void main(String[] args) throws Exception {
          // Read xml and build a DOM document
          Document doc = DocumentBuilderFactory.newInstance()
                    .newDocumentBuilder().parse(new InputSource(inputFile));
          // Use XPath to find all nodes where student is named 'Suresh'
          XPath xpath = XPathFactory.newInstance().newXPath();
          NodeList nodes = (NodeList)xpath
               .evaluate("//stud_name[text()='Suresh']", doc, XPathConstants.NODESET);
          // Rename these nodes
          for (int idx = 0; idx < nodes.getLength(); idx++) {
               nodes.item(idx).setTextContent("Suresh-Renamed");
          // Write the DOM document to the file
          Transformer xformer = TransformerFactory.newInstance().newTransformer();
          xformer.transform(new DOMSource(doc), new StreamResult(new File(outputFile)));

XML-Beans or JAXB?

Folks,
I'm maintaining a map building webapp which is a few years old now.
The user navigates up to a dozen HTML forms which build up a "profile" of the required map. The webapp sends the complete "profile" to a "mapping" tuxedo service, which builds a PDF document of the map and returns it through the webapp to the client, which displays it in Adobe reader.
I've taken "issue" with the volume of code we have around building the XML "profile" from the various request parameters. I'm thinking about replacing it with an XML binder, but which one?
I've been reading up on XML Beans and JAXB, and both look good to me. We're using weblogic 8.1 server, which I believe supports XML beans annotations... very cute.
I had a bit of a google and turned up a couple of old threads, and some product announcements, but no nice meaty white papers, and nothing really since 2004... I presume things have changed in three years.
Thanx in advance. Keith.

george,
We're allready using xalan & xerces (both in Java and C++) which extend XMLBeans capabilities, and weblogic has support for XMLBeans built into it.
We're not currently using any XML-binder in this application, so it's about 5,000 lines bigger than it needs to be... but I've just discovered that we are using XML beans in another (newer) web-application which is maintained by our "sister team"... so I'll get their guru's to talk to our guru's, and hopefully I won't have to make an airtight case for change all by myself... just a watertight one, with a little help from some elevated friends.
So... I think I'll try an XMLBeans prototype and see how it goes.
thanx. keith.

Preprocessing xml to replace all xpath references with the referred elements

Hi,
Is it possible to sort of pre-process xml before querying such as we replace all internal xpath references with the referred elements?
So below is the xml and as we see the typeId element of second app.test.module.library.Publisher element refers to the typeId element in the first app.test.module.library.Publisher element through xpath reference . Seems this is done by XStream(which we
use for xml-java) to reduce the size of resulting xml. This is all fine and in java one can easily traverse through such xpath references, but the challenge i am facing is in sql where i use node() function to get each of app.test.module.library.Publisher
element and fetch value of selectedText element of both the children of app.test.module.library.Publisher - (typeId, regionCode).
declare @publishers xml
set @publishers = '
<publishers>
<app.test.module.library.Publisher>
    <typeId>
      <selectedId>101</selectedId>
      <selectedText>Book</selectedText>
    </typeId>
    <regionCode>
      <selectedId>102</selectedId>
      <selectedText>NWD</selectedText>
    </regionCode>
</app.test.module.library.Publisher>
<app.test.module.library.Publisher>
    <typeId reference="../../app.test.module.library.Publisher/typeId" />
    <regionCode>
      <selectedId>101</selectedId>
      <selectedText>UWY</selectedText>
    </regionCode>
</app.test.module.library.Publisher>
<app.test.module.library.Publisher>
    <typeId>
      <selectedId>100</selectedId>
      <selectedText>Deposit</selectedText>
    </typeId>
    <regionCode>
      <selectedId>100</selectedId>
      <selectedText>WHU</selectedText>
    </regionCode>
</app.test.module.library.Publisher>
</publishers>';
select typeId = el.e.value('(typeId/selectedText)[1]','varchar(max)')
      ,regionCode = el.e.value('(regionCode/selectedText)[1]','varchar(max)')
from @publishers.nodes('/publishers/app.test.module.library.Publisher') as el(e)
If you execute this, the second typeId value will be null but ideally I should be able to reach to the reference, which is typeId of first app.test.module.library.Publisher element and should be able to fetch selectedText of it, which is correct value (Book).
In other words first two app.test.module.library.Publisher elements are of same type (Book).
Since I am not able to find the way to do it, I thought I should have some way to process this xml to replace all such references with the referred element and that will eliminate the need to go for tedious xpath reference based access.
Thanks

I was able to get a result using dynamic SQL, but my guess is if you have more complicated examples it probably won't work. I also make an assumption you know the full path of the first reference you want. Anyway, try this:
DECLARE @xml XML = '<publishers>
<app.test.module.library.Publisher>
<typeId>
<selectedId>101</selectedId>
<selectedText>Book</selectedText>
</typeId>
<regionCode>
<selectedId>102</selectedId>
<selectedText>NWD</selectedText>
</regionCode>
</app.test.module.library.Publisher>
<app.test.module.library.Publisher>

<typeId reference="../../app.test.module.library.Publisher/typeId" />
<regionCode>
<selectedId>101</selectedId>
<selectedText>UWY</selectedText>
</regionCode>
</app.test.module.library.Publisher>
<app.test.module.library.Publisher>
<typeId>
<selectedId>100</selectedId>
<selectedText>Deposit</selectedText>
</typeId>
<regionCode>
<selectedId>100</selectedId>
<selectedText>WHU</selectedText>
</regionCode>
</app.test.module.library.Publisher>
</publishers>'
-- So you basically need to create and execute this string;
-- but how do you work out the first bit of the string ?
--SELECT @xml.query('(publishers/app.test.module.library.Publisher/typeId/../../app.test.module.library.Publisher/typeId)[1]');
DECLARE @fullPath NVARCHAR(MAX) = 'publishers/app.test.module.library.Publisher/typeId/@reference' -- the full path of the reference
DECLARE @shortPath NVARCHAR(MAX) = LEFT( @fullPath, CHARINDEX( '@', @fullPath ) - 1 ) -- full path without attribute name
IF @shortPath IS NULL
RAISERROR ( 'Unable to get @shortPath.', 16, 1 )
-- Start processing the XML
DECLARE @sql NVARCHAR(MAX), @reference NVARCHAR(MAX)
-- Extract the reference
SET @reference = @xml.value('(publishers/app.test.module.library.Publisher/typeId/@reference)[1]', 'NVARCHAR(MAX)')
-- Construct the sql
SET @sql = 'SELECT @xml.query(''(' + @shortPath + @reference + ')[1]'')'
-- Execute the SQL
EXEC sp_executesql @sql, N'@sql NVARCHAR(MAX), @xml XML', @sql, @xml
Post back any issues you have with that approach and your real data.

How to configure multiple jsp files with diff beans in faces-config.xml??

Is the below way correct???

Thanks ejp for the reply.
Since i am a beginner even i dont know the exact reason to answer you for why am i using JSP with Facelets.Kindly provide me the suggestion and valuable information you have so that i can learn.
Apart from this i want to know whether the way provided in that faces-config.xml is possible or do we have a way to make that possible???

Generating an XML representation of arbitrary Java objects

I'm having some trouble figuring out how to implement the XMLDAO.getObject(Node n) method. I was thinking of maintaining a Stack of the previous Objects as I traverse the DOM, but I think that might be unnecessary work. Basically I'm wondering how I determine what the last "object" is in the DOM from any given node. Anyone have any input?

I think the end of my post got cut off:

can any body tell me how to validate the repeating tags (as i dont have dtd for this xml )with the given code.... if any one of the tags are repeating it should raise an exception thats its not a valid xml
Thanks in advance
Regards

I suggest you create a DTD or a XSD file to validate your existing XML document, because it's easier that i looks, and will help in future changes.
If you want to do it in Java code, you can always store each line of the XML file in some form (like a class) in a List, and the each time you read a line, you compare with everything on the list.
But don't go that way, make a XSD file

The first problem about this document is that it contains a space at the very first position whereas <?xml... must appear at the very beginning of a document. I think this was the cause of the parsing fault.
Also you have a dash before the root element of the document, which is illegal.

Calling XML API's from Java Stored Procedures in DB

Hi,
I am have and Oracle 10gR2 db installed and XML Publisher Enterprise Server 5.6.2.
I have created the following Java Class and used loadjava to make it a Java Stored Procedure:
<code>
import java.io.IOException;
import java.lang.Object;
import oracle.apps.xdo.XDOException;
import oracle.apps.xdo.template.FOProcessor;
import oracle.apps.xdo.template.RTFProcessor;
public class callingXMLP{
public static String rtfToXsl(String rtfFile, String xslFile)
try {
RTFProcessor rtfProcessor = new RTFProcessor(rtfFile); //Input RTF
rtfProcessor.setOutput(xslFile);
rtfProcessor.process();
} catch (IOException IOE) {
return" Error "+IOE.getMessage();}
catch(XDOException XDE ){
return" Error "+XDE.getMessage();
return "Success";
public static String mergeXmlXsl(String xmlFile, String xslFile, String outputFile)
FOProcessor processor = new FOProcessor();
processor.setData(xmlFile); //Input XML File
processor.setTemplate(xslFile); //Input XSL File
processor.setOutput(outputFile); //Ouput File
processor.setOutputFormat(FOProcessor.FORMAT_PDF);
//start processing
try {
processor.generate();
catch (XDOException e){
e.printStackTrace();
//System.exit(1);
return "Error - "+e.getMessage();
//System.exit(0);
return "Success";
</code>
I then wrap this using the following function spec in pl/sql:
create or replace function callXMLP(input1 VARCHAR2, output1 VARCHAR2) RETURN VARCHAR2
as language java name 'callingXMLP.rtfToXsl(java.lang.String,java.lang.String) return java.lang.String';
and
create or replace function mergeXMLXSL(xml VARCHAR2, xsl VARCHAR2, output VARCHAR2) RETURN VARCHAR2
as language java name 'callingXMLP.mergeXmlXsl(java.lang.String,java.lang.String,java.lang.String) return java.lang.String';
Calling the callXMLP function works fine, and produces an XSL file from the input RTF file as expected.
When I run the mergeXMLXSL function, it says that the function has completed successfully, but it seems to be throwing an XDOException error as it is returning "Error - null" message from the Java.
A PDF document is being created, but it does not have any content. I have also modified the Java to create an RTF instead, but still the same thing happens.
Is there anything that I need to check, or something that I am missing when trying to create the final PDF document?
Please help, I am completely stuck with this now.
Many Thanks,
Cj

How to use XML bean in 9.1 web service.

hi,
im trying to deploy a small web service with only one method in WLS 9.1.
That method accepts an XMLbean as the input parameter and returns the same type of xmlBean as the output.
how can i specify the name of corresponding .xsd file in the ant script.
the source code of web service file is given below.
Please have a look at it and help me.
package com.test;
import javax.jws.WebService;
import com.mlt.eai.login.LoginDocument;
import java.util.Date;
@WebService(name="LoginServiceType", serviceName="LoginService")

new Dealer(lInfo.getLogin().
getRequest().getInputData().getLoginID(), lInfo.getLogin().getRequest().getInputData().getPassoword(), new Date());
if(dealer.doIFSAuthentication()){
lInfo.getLogin().getResponse().getResult().setReturnCode(1);
lInfo.getLogin().getResponse().getResult().setReturnMessage("Session Started");
else{
lInfo.getLogin().getResponse().getResult().setReturnCode(0);
lInfo.getLogin().getResponse().getResult().setReturnMessage("Invalid username / password");

XML Beans and Weblogic Server 8.1

Hi,
Does anyone know if XML beans is shipped with Weblogic 8.x (or is it only part
of the Weblogic Workshop) ?
Thanks,
Arun

Greg,
The classes required for running these command line tools are all there, but
we have not put the script files in the version bundled with WebLogic
server. Its very likely to be part of the next service pack release.
Meanwhile, you can always run the classes from the command line, or write
your own script. For instance, the dumpxsb.cmd has the following:
set cp=
set cp=%cp%;%XMLBEANDIR%\xbean.jar
java -classpath %cp% com.bea.xbean.tool.XsbDumper %*
So you can always write this on your own, or just run the concerned class
from the command line.
Let me know if you have any further queries.
Regards,
Anurag

Hi,
Is it possible to use the version of xmlbeans bundled with workshop in a
standalone sense? Are all the command line tools there? If so can yougive
a pointer to where abouts in the Workshop download to look for this.
The reason I ask is noting the following I saw -:
Note: XQuery is currently only available with the version of XMLBeans
included with WebLogic Platform. We hope to add these capabilities to the
stand-alone version soon.

Arun,
WebLogic Platform 8.1 GA which includes Workshop does contain an
xmlbeans
implementation.
We also have a stand alone implementation which is available on dev2dev.
Thanks

Thanks. But what we have found out from BEA is that it does not shipwith Weblogic
Server. You have to download it separately.

Server
8.1
too). Although the version is slightly older than the version
available
on the
dev2dev site.

Is XML-SQL Utility for Java run on Client Side?

A question about the XML-SQL Utility for Java
When a client program connect to a Oracle database (the clinet program and Oracle DB is run on two different machine. Oracle 8i is used) and use the oracle.xml.sql.query.OracleXMLQuery Class (form the XSU) to generate XML by given a SQL query. I want to know the transforation process is execute in the Clinet side or the database?
Is there any method that i can retrieve the XML directly from the database rather then doing the transformation form the Client side?

Set JDK_HOME to the directory where you install your JDK (Java Development Kit).
So instance, I've install JDK1.1.8 on my
C drive so
set JDK_HOME=c:\jdk1.1.8;c:\jdk1.1.8\bin

NullpointerException while returning XML bean from JDBC Control

Hi,
I have a simple jdbc control method which returns multiple rows of a table. i am trying to get the data in XML bean format and followed the instruction provided in the help documentation.
None of the columns in table has null values.
The exception I am getting is
Exception in getActiveAlertList
java.lang.NullPointerException
at org.apache.beehive.controls.system.jdbc.RowToXmlObjectMapper.mapRowToReturnType(RowToXmlObjectMapper.java:102)

at org.apache.beehive.controls.system.jdbc.JdbcControlImpl.invoke(JdbcControlImpl.java:223)
Any help is appreciated.

Hi!
I?m facing this same problem.
Have you found a solution?
I also tried to migrate an WL 8 application, that works with a DB Control, but got the error anyway.
If you, or someone else, found the solution, please share. I?d appreciate.
Thanks.
