Returning XML Document

I am having trouble (weblogic 7.0) exposing an EJB web service. It
takes string parameters in and should return an XML document. I've
ported this from apache axis, the java method takes java.lang.String
parameters and returns org.w3c.dom.Element ... this works fine on
Jboss 3.2.0. Can anyone help me figure out how to do the same on
weblogic? My web-services.xml file is as follows now:
<web-services>
     <web-service name="myService"
targetNamespace="http://www.bobo.com"
uri="/jboss-net/services/myService">
          <components>

Hello,
Are you using servicegen against the EJB?
http://edocs.bea.com/wls/docs81/webserv/anttasks.html#1063540
Using a stateless session EJB example can be found here:
http://webservice.bea.com/statelessSession.zip and there is a dom
example here: http://webservice.bea.com/dom.zip
Thanks,
Bruce

Webservices: returning xml document to client

Can anyone please help me to the following problem.
1. I have a java bean which i publish as webservice. I want to return an xml document on request from client(for time being my client is normal java client). when i call getDoc() from client i get classload exception. can anyone explain me why?
public org.w3c.dom.Document getDoc() throws java.rmi.RemoteException {
Document document = null;
DocumentBuilderFactory factory =
DocumentBuilderFactory.newInstance();
try {
DocumentBuilder builder = factory.newDocumentBuilder();
document = builder.parse( new File("C:\\data\\RND\\XmlParser\\XmlParser\\src\\xmlparser\\employer.xml"));
catch (Exception ex) {
return document;
2. if i have to send a xml file to clinet on request using web services(i assume i cant return an document as above), is it feasible(my xml file is a transaction file) to send a xml file as string?
3. how to transfer a xml file into a string?

I'm almost sure that the error is because the Document class is not supported by JAX-RPC (see page 384 of the Java Web Services Tutorial).
Try sending your XML as a String.
This code may help you to transform between XML and String and viceversa:
import javax.xml.parsers.*;
import javax.xml.transform.*;
import org.xml.sax.*;
import org.w3c.dom.*;
public static Document toXmlDocument(String xml) throws IOException, SAXException, ParserConfigurationException
StringReader reader = new StringReader(xml);
InputSource source = new InputSource(reader);
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document xmlDoc = builder.parse(source);
return ( xmlDoc );
public static String toXmlString(Node node) throws TransformerConfigurationException, TransformerException
StringWriter writer = new StringWriter();
DOMSource source = new DOMSource(node);
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer();
StreamResult result = new StreamResult(writer);
transformer.transform(source,result);
return ( writer.toString() );
}

Return XML document through Web Service?

Hello,
Is it possible to return a XML document from a web service?
For example, I have a Oracle Report that outputs in XML format, is it possible to return that through a web service?
Any suggestions or pointers will be most appreciated.

Hi Nilan,
You can see a simple example here.,on how to pass and receive XML elements as web service params.

How to parse XML document returned by webservices

Hi,
I have a form (version 10.1.2.0) which has to display the credit card types using webservices. I created the webstub and jar file through jdeveloper and then after adding the jar files in the respective classpaths, I import it in the forms. I write the code in when-button-pressed and it gives the result in xml document like this:
<?xml version="1.0" encoding="UTF-8"?><WSAnswerTO><error>false</error><errorMessage></errorMessage><
results><CardTypeTO><carTypId>3</carTypId><type>AMERICAN
EXPRESS</type><numLength>15</numLength><cvvLength>4</cvvLength><comments>1 800-639-0002</comments></CardTypeTO><CardTypeTO><carTypId>4</carTypId><type>DISCOVER</type><numLength>16</numLength><cvvLength>3</cvvLength><comments>1 800-347-2683</comments></CardTypeTO><CardTypeTO><carTypId>1</carTypId><type>MASTERCARD</type><numLength>16</numLength><cvvLength>3</cvvLength><comments>1 800-633-7367</comments></CardTypeTO><CardTypeTO><carTypId>2</carTypId><type>VISA</type><numLength>16</numLength><cvvLength>3</cvvLength><comments>1 800-945-2000</comments></CardTypeTO></results></WSAnswerTO>
From the above xml document, I only need to display the type (such as AMERICAN EXPRESS, VISA, ETC) in my forms. Can somebody please tell me how to do it. Do I need to store the values in a table first and then retrieve it. Please advise. I have already read a otn document in xml parsing but I didnt understand anything from it.
Please help. Thanks in advance.

Carriage Returns & Line Feeds in XML documents

Does anyone know why the PL/SQL XML parser will NOT work with Carriage Returns (0x0D) within the XML document?
Currently I'm having to strip them out, leaving just the Line Feed (0x0A).
I only realised this after looking at the family.xml example document.

I forgot to mention that I'm running Oracle 8i on Windows NT.

My Task is To Parse a XML Document to Return CLOB's

Hi folks
I am writing this mail in the hope of getting a help.Please
give me a shoulder to keep me going.
The task is to parse a XML document for a specific Tag and
read the Tag content in CLOB to return CLOB.
I know that the writetoclob will do the job as
per oracle documentation.
I am giving the code where i got stuck.
Please help me complete my rest of coding.
Thanks
Input variables are
XMLin in CLOB, -- Incoming XML Document Structure
Partype in varchar2, -- Tagname
Result out CLOB -- Return Tag value CLOB data type.
My Code : -
Declare
p xmlparser.parser;
d xmldom.DOMDocument;
e xmldom.DOMElement;
nl xmldom.DOMNodeList;
n xmldom.DOMNode;
tagvalue varchar2(255);
paramsIn Clob;
result CLOB;
BEGIN
--loading SecXML
dbms_lob.createtemporary(paramsIn,true);
dbms_lob.append(paramsIn,XMLin);
--dbms_output.put_line('ParsebyTag ='||Partype);
--defining parser
p := xmlparser.newparser;
xmlparser.parseClob(p,paramsIn);
d := xmlparser.getDocument(p);
--get tagvalue
nl := xmldom.getElementsByTagName(d,partype);
n := xmldom.item(nl,0);
IF xmldom.getlength (nl) > 0
THEN
n := xmldom.item (nl, 0);
=>=>=> => xmldom.writetoclob (n, result); <=<=<=<=<=<=====
END IF;
return; -- from a procedure
The above line marked with a arrow does not work for CLOB Variables.
Please explain with a corrected code to complete this task.
Thanks for reading my request.

First, you have 2 variables with the same name,
Second, let me show you what is that you need to do:
PROCEDURE WriteDataToClob(XMLin in CLOB, Partype in varchar2, Result out CLOB) IS
Declare
p xmlparser.parser;
d xmldom.DOMDocument;
e xmldom.DOMElement;
nl xmldom.DOMNodeList;
n xmldom.DOMNode;
tagvalue varchar2(255);
TempClob Clob;
BEGIN
--Create a temporary clob
dbms_lob.createtemporary(TempClob,true);
--loading SecXML
--defining parser
p := xmlparser.newparser;
xmlparser.parseClob(p,XMLin);
d := xmlparser.getDocument(p);
--get tagvalue
nl := xmldom.getElementsByTagName(d,partype);
n := xmldom.item(nl,0);
IF xmldom.getlength (nl) > 0 THEN
n := xmldom.item (nl, 0);
xmldom.writetoclob (n, TempClob );
END IF;
Result := TempClob;
dbms_lob.FreeTemporary(TempClob);

How to check empty return from Get XML Document Data?

If Get XML Document Data doesn't return a result, how do you test it? String.isEmpty() doesn't do the trick, it still throws the exception "java.lang.NullPointerException". I can't seem to be able to match that up to a cisco exception with a "On Exception Goto" step (which I put right before the XML Document Data step). Any clues anyone?

Hi,
Try this:
variable=Get XML Document Data ()
if(variable == null) then
true
false

UCCX XPath on Get XML Document Data Step always returns null

Hello,
Can someone tell whats wrong with my XPath, because it always returns null. I have tried different variations and nothing. I'm using UCCX 7.0
XML
<?xml version="1.0" encoding="utf-8" ?>
<GetManagersResult xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://www.labdomain.com/">
<ClaimManagersList>
    <X_CLAIM_MANAGER>
      <ClaimManagerUserName>test</ClaimManagerUserName>
    </X_CLAIM_MANAGER>
</ClaimManagersList>
</GetManagersResult>
XPATH
"/descendant::GetManagersResult/child::ClaimManagersList/child::X_CLAIM_MANAGER/child::ClaimManagerUserName"
During debug, this is the value of the xml document when it reaches the Get XML Document Data step:
TEXT[<?xml version=\"1.0\" encoding=\"UTF-8\"?>\r\n<GetManagersResult xmlns=\"http://www.labdomain.com/\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\">\r\n <ClaimManagersList>\r\n    <X_CLAIM_MANAGER>\r\n      <ClaimManagerUserName>test</ClaimManagerUserName>\r\n    </X_CLAIM_MANAGER>\r\n </ClaimManagersList>\r\n</GetManagersResult>]

It's your XML namespace in the root element.
First off, I have never seen the CRS Editor play nice when XML namespaces are involved.
Secondly, with your namespace in place, not even a generic xpath expression tester can find your data. See attachements.
I think that if you find a way to either: not send, or remove the namespace from your document, your xpath expression will work.

Get XML Document Data step always returns NULL

Hi All,
I was hoping someone might be able to help with this.
I'm writing a holiday script, it uses XML to check whether the date is a holiday or halfday. XML below
<?xml version="1.0" encoding="ISO-8859-1"?>

<Holiday Date="19/10/2012">Halfday</Holiday>
</Holidays>
However when I debug the script the result of the Get XML Document step always returns null.
Xpath work great in notepad++
My code is attached, anyone with any pointers?
Regards,
Andy

Your XPATH of:
"/Holidays/Holiday[@Date='+DateString+']"
Needs to be:
"/Holidays/Holiday[@Date='"+DateString+"']"
Good luck and happy scripting!

Error while loading an XML document using a structured application

Hi,
I try to load an XML document using a structured application defined in the default structapps.fm
My code is shown down, extracted from the FDK API code sample.
Problem, I always have the same message :
"Cannot find the file named e:\xml\AdobeFrameMaker10\file. Make sure that the file exists. "
Where "e:\xml\AdobeFrameMaker10\" is my install directory.
So I assume that frame try to find the structapps.fm file but does not find it.
What else can it be ?
Does anyone knowns how to achieve this simple task using extendScript ?
Thanks for any comments, Pierre
function openXMLFile(myLastFile) {
    var filename = myLastFile.openDlg("Choose XML file ...", "*.xml", false);
    if (filename != null) {
        /* Get default open properties. Return if it can’t be allocated. */
        var params = GetOpenDefaultParams();

Pierre,
Depending on the object "myLastFile", the method openDlg might not even exist (if the myLastFile object is not a File object, for instance). And I do not see any need for the myLastFile anyhow, as you are presenting a dialog to select a file to open. I recommend using the global ChooseFile( ) method instead. This will give you a filename as string in full path notation, or null when no file was selected in the dialog. I am not sure what your ExtendScript documentation states about the return value for ChooseFile, but if that differs from what I am telling you here, the documentation is wrong. So, if you replace the first lines of your code with the following it should work:
function openXMLFile ( ) {
    var filename = ChooseFile ( "Choose XML file ...", "", "*.xml", Constants.FV_ChooseSelect );
While writing this, I see that Russ has already given you the same advice. Use the symbolic constant value I indicated to use the ChooseFile dialog to select a single file (it can also be used to select a directory or open a file - but you want to control the opening process yourself). Note that this method allows you to set a start directory for the dialog (second parameter). The ESTK autocompletion also gives you a fifth parameter "helplink" which is undocumented and can safely be ignored.
Good luck

Problem replacing Null nodes with real values in XML documents...

Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit Production
Our friends in Java land are insisting on passing data between Java and PL/SQL using fairly small XML documents (don't ask). I then need to extract the input parameter values and pass them, on to the stored procedures that actually do the work. These return a result which needs to be returned to the java layer in the output XML document.
Here is a cut down version of the input XML...
<ParameterList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Parameter>
<Id>1</Id>
<Result xsi:nil="true"/>
</Parameter>
<Parameter>
<Id>2</Id>
<Result xsi:nil="true"/>
</Parameter>
</ParameterList>
and this is an example of what I am expected to return...
<ParameterList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Parameter>
<Id>1</Id>
*<Result>SUCCESS</Result>*
</Parameter>
<Parameter>
<Id>2</Id>
*<Result>WARNING</Result>*
</Parameter>
</ParameterList>
i.e. I am expected to replace the value of the Result node with a string indicating the succes or otherwise of the underlying PL/SQL process.
I am extracting the input values using the DBMS_XMLDOM functions and naively assumed that DBMS_XMLDOM.SETNODEVALUE could be used to update the value in the Result node - It didn't work so I resorted to reading the documentation which revealed that it will not work for a null node.
Am I going to have to use XSLT to generate the output XML from the Input and incorprate the result? Or is there a simpler way?
I have used XSLT in Oracle before and still have the nervous tick...

Thanks A Non,
With your suggestion and a bit of help from the w3schools.com xml dom tutorial I eventually managed to work out how to do this.
Here is the code (with all my debug stuff in so it looks worse than it is...)
create or replace

and the output...

</ParameterList>
One question, why do the dbms_xmldom functions return the Old value? I was expecting the returned value to be the updated node.

Is there a way to modify the style sheet so that it transforms an XML document with empty tags as tag / ?

I have extracted some code from codeproject to
reindent an XML document. Does anyone know how I can modify the stylesheet to make it so that the transform of an XML file will result in empty tags showing up as <tag /> instead of <tag></tag>?
// http://www.codeproject.com/Articles/43309/How-to-create-a-simple-XML-file-using-MSXML-in-C
MSXML2::IXMLDOMDocumentPtr FormatDOMDocument(MSXML2::IXMLDOMDocumentPtr pDoc)
LPCSTR const static szStyleSheet =
R"!(<?xml version="1.0" encoding="utf-8"?>)!"
R"!(<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">)!"
R"!( <xsl:output method="xml" indent="yes"/>)!"
R"!( <xsl:template match="@* | node()">)!"
R"!( <xsl:copy>)!"
R"!( <xsl:apply-templates select="@* | node()"/>)!"
R"!( </xsl:copy>)!"
R"!( </xsl:template>)!"
R"!(</xsl:stylesheet>)!";
MSXML2::IXMLDOMDocumentPtr pXmlStyleSheet;
pXmlStyleSheet.CreateInstance(__uuidof(MSXML2::DOMDocument60));
pXmlStyleSheet->loadXML(szStyleSheet);
MSXML2::IXMLDOMDocumentPtr pXmlFormattedDoc;
pXmlFormattedDoc.CreateInstance(__uuidof(MSXML2::DOMDocument60));
CComPtr<IDispatch> pDispatch;
HRESULT hr = pXmlFormattedDoc->QueryInterface(IID_IDispatch, (void**)&pDispatch);
if (SUCCEEDED(hr))
_variant_t vtOutObject;
vtOutObject.vt = VT_DISPATCH;
vtOutObject.pdispVal = pDispatch;
vtOutObject.pdispVal->AddRef();
hr = pDoc->transformNodeToObject(pXmlStyleSheet, vtOutObject);
//By default it is writing the encoding = UTF-16. Let us change the encoding to UTF-8
// <?xml version="1.0" encoding="UTF-8"?>
MSXML2::IXMLDOMNodePtr pXMLFirstChild = pXmlFormattedDoc->GetfirstChild();
// A map of the a attributes (vesrsion, encoding) values (1.0, UTF-8) pair
MSXML2::IXMLDOMNamedNodeMapPtr pXMLAttributeMap = pXMLFirstChild->Getattributes();
MSXML2::IXMLDOMNodePtr pXMLEncodNode = pXMLAttributeMap->getNamedItem(_T("encoding"));
pXMLEncodNode->PutnodeValue(_T("UTF-8")); //encoding = UTF-8
return pXmlFormattedDoc;
Or, if there is some other method for reindenting a MSXML2::IXMLDOMDocumentPtr object where I can specify how I want empty tags to be stored, that would be great too. However, I don't want it to lose its status of an MSXML2::IXMLDOMDocumentPtr object.
I.e. I would like to still perform operations on the result as if it was still an MSXML2::IXMLDOMDocumentPtr object.
Thanks,

Heap space error while creating XML document from Resultset

I am getting Heap space error while creating XML document from Resultset.
It was working fine from small result set object but when the size of resultset was more than 25,000, heap space error
I am already using -Xms32m -Xmx1024m
Is there a way to directly write to xml file from resultset instead of creating the whole document first and then writing it to file? Code examples please?
here is my code:
stmt = conn.prepareStatement(sql);
result = stmt.executeQuery();
result.setFetchSize(999);
Document doc = JDBCUtil.toDocument(result, Application.BANK_ID, interfaceType, Application.VERSION);
JDBCUtil.write(doc, fileName);
public static Document toDocument(ResultSet rs, String bankId, String interfaceFileType, String version)
    throws ParserConfigurationException, SQLException {
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        DocumentBuilder builder = factory.newDocumentBuilder();
        Document doc = builder.newDocument();
        Element results = doc.createElement("sims");
        results.setAttribute("bank", bankId);
        results.setAttribute("record_type", "HEADER");
        results.setAttribute("file_type", interfaceFileType);
        results.setAttribute("version", version);
        doc.appendChild(results);
        ResultSetMetaData rsmd = rs.getMetaData();
        int colCount = rsmd.getColumnCount();
        String columnName="";
        Object value;
        while (rs.next()) {
            Element row = doc.createElement("rec");
            results.appendChild(row);
            for (int i = 1; i <= colCount; i++) {
                columnName = rsmd.getColumnLabel(i);
                value = rs.getObject(i);
                Element node = doc.createElement(columnName);
                if(value != null)
                    node.appendChild(doc.createTextNode(value.toString()));
                else
                    node.appendChild(doc.createTextNode(""));
                row.appendChild(node);
        return doc;
public static void write(Document document, String filename) {
        //long start = System.currentTimeMillis();
        // lets write to a file
        OutputFormat format = new OutputFormat(document); // Serialize DOM
        format.setIndent(2);
        format.setLineSeparator(System.getProperty("line.separator"));
        format.setLineWidth(80);
        try {
            FileWriter writer = new FileWriter(filename);
            BufferedWriter buf = new BufferedWriter(writer);
            XMLSerializer FileSerial = new XMLSerializer(writer, format);
            FileSerial.asDOMSerializer(); // As a DOM Serializer
            FileSerial.serialize(document);
            writer.close();
        } catch (IOException ioe) {
            ioe.printStackTrace();
        //long end = System.currentTimeMillis();
        //System.err.println("W3C File write time :" + (end - start) + " " + filename);
    }

you can increase your heap size..... try setting this as your environment variable.....
variable: JAVA_OPTS
value: -Xms512m -Xmx1024m -XX:PermSize=256m -XX:MaxPermSize=512m
