Handling empty values during xml validation
Hello experts,
I have a file to file scenario in PI 7.1. I am using xml validation to validate the incoming source file. There are various types of fields in the incoming file including int, decimal and string. They can have a certain enumeration of values but can also have a blank value.
For example field 'Num' of type int can have values 1,2,3 or a blank value.
But I am not able to define a blank value for the field in the enumeration during definition. Therefore a blank value in the input file fails during the validation stage.
Is there any workaround for this?
Thanks!

This is a basic problem. When you define a field as integer you cannot declare blank space which represents String type.
So for your case make the value 'zero' instead of blank, if you want do declare the field as integer and as below...
<xs:element name="Num">
<xs:simpleType>
<xs:restriction base="xs:integer">
<xs:pattern value="[0-3]"/>
</xs:restriction>
</xs:simpleType>
</xs:element>

Java.lang.Exception error during XML validation by Integration Engine
Hi professionals,
We are trying to use XML validation by the Integration Engine.
Step 1:
We created an appropriate directory structure where we had to store the structure (xsd).
\usr\sap\<system id>\SYS\global\xi\runtime_server\A\B\C\D\E\F
A - validation
B - schema
C - GUID of the SWCV where service interface reside.
D - Repository Namespace where Service Interface is created.
E - Service Interface Name
F - Repository Namespace where Message Type or External Definition is
assigned.
Step 2:
We also changed the references in the xsd to exclude all the subdirectory references.
e.g folder1/folder2/abc.xsd is become abc.xsd only
Step 3:
We stored both xsdu2019s (schema xsd and referenced xsd to the directory created in step 1)
Step 4:
We changed the directory and xsdu2019s permissions to 777 (we chose 777 for testing purpose).
Step 5:
We changed the property schema validation of the sender agreement to Validation by Integration Engine.
Step 6:
We checked RFC destination for AI_VALIDATION_JCOSERVER on AS ABAP and AS Java and establish an successful connection test.
RESTULTS
The result of those steps is an error message in the message monitor of PI with the error tekst:
<SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="">

Please assist in how to solve this issueu2026.
Regards, Sjaak.I would suggest follow Appendix A to know the exact path and since you have one XSD referring other XSD check the steps mentioned in Appendix B .... there seems to be some error in referencing ...Appendix A and B are on page 12 & 13 of this document:

"semantic checks during XML Validation"
What did SAP pepole ment saying the above subject in the XML validation page of PI 7.3?
Does PI supprots only "shallow" validation of structure rather then "deep validaiton" of data type patterns for example?
if not duiring validation then when?

How to handle empty value coming to PI
Hi Experts,
My scenario is ABAP proxy to File. ABAP program is sending data to PI with blank value. But in PI payload that field is not showing at all.
Suppose customer number value is blank in ABAP internal table, in PI payload customer number xml tag is not showing at all in source structure.
Have used one to one mapping and in content conversion we have used.
.addHeaderLine 0
.fieldSeparator ;
endSeparator 'nl'
and also I need - if any value in the source structure is coming empty we need to replace it with semi colon.it is not for a specific field, it might be any field of source structure.
please help on this.
Thanks,
SwapnashreeHi,
Before you call the message mapping in interface mapping, u need a java mapping code. This code will check if the required tag is absent. In case the required XML tag is missing, the java mapping code will insert the tag under proper parent node. This is best accomplished using DOM parser. If you need any further guidance from forum members on how to achieve this, then you need to publish following information
1. Version of PI you are working on.
2. Source XML structure.
3. Target XML structure.
You may refer to various java mapping blogs in SDN for further information on the topic.
Else try this mapping of the source field
Source field--------Exists ------> if ----------------- target field
if the condition evaluates true then map source field -------> target else constant (";") ------->target.

This is strange, because I didn't configure any XML validation. I didn't configure that explicitly.
However, I noticed that the step "XML Validation Inbound Channel Request ( CENTRAL )" is executed every time I send messages to PI. Normally this is successful, so the message flow is not interrupted. But even in the successful case the xml header is always cut off (so the line "<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>" in the beginning). I checked other messages with different adapters, and this step is never executed.
I would like to know whether this step can be switched off somewhere or whether it is performed by default. Does anybody know more about this topic?
Best regards,
JörgHi Hema,
As per understanding you need to check one or few fields value is integer or not.
You can achieve in 2 ways :
Case1:Using inbuilt xml validation options.
For 7.11 and below
1)In ESR/Message type/Export the xsd to local machine.
2)Insert the xsd file in the below loc
/usr/sap/<sid>/DVEBMGS00/j2ee/cluster/server0/validation/schema/
<guid>/<namespace1>/<service_interface_name>/<namespace2>
<sid>: System ID of the server instance.
<guid>: The GUID of the SWCV.
<namespace1> : The namespace within which the service interface is defined.
<service_interface_name> : The name of the service interface.
<namespace2>
: The namespace of the Message Type used by the service interface. In many
instances, namespace1 and namespace2 are the same.
Italic path folders need to create by you.
For 7.3 and above
Michal's PI tips: XML validation - changes in 7.3
Case 2 :Handling using simple UDF.
Input-->UDF-->Output
try {
Integer.parseInt(input);
return input ;
catch(NumberFormatException e) {
throw new StreamTransformationException( "Input field value for xyz field "+input+"is not in integer format.Plz correct it");

How to obtain XML error node after XML validation
Hello,
We are developing a web application which uses XML documents.
We try to obtain the exact error which occurs during XML validation against a schema in order to alert users with a proper message - for example: "Invalid value for element date".
We validate our XML documents using DBMS_xmlparser. But it only retuns a string message indicating there is an error and document cannot be validated. What can we use to reference to the node object which contains the error?
We develop our application under Oracle 9.2.0.4.
Any help will be appreciated.Validate with a DOMParser or a SAXParser.
Set a ErrorHandler on the parser.
The custom ErrorHandler class should override the startElement & endElement methods of the DefaultHandler class.
private class Validator extends DefaultHandler
public boolean validationError = false;
public SAXParseException saxParseException=null;
public void error(SAXParseException exception) throws SAXException
validationError = true;
saxParseException=exception;
public void fatalError(SAXParseException exception) throws SAXException
validationError = true;
saxParseException=exception;
public void warning(SAXParseException exception) throws SAXException

String localName,
String qName,

throws SAXException{
System.out.println("Start Element: "+qName);

venkat.Hi Venky,
This error due to incorrect path So please check whether you have used the correct path or not?
Create appropriate directories structure where we have to save your structure (xsd).
\usr\sap\<system id>\SYS\global\xi\runtime_server\A\B\C\D\E\F
A - validation
B - schema
C - GUID of the SWCV where service interface reside.
D - Repository Namespace where Service Interface is created.
E - Service Interface Name
F - Repository Namespace where Message Type or External Definition is assigned.
Note: if your ESR namespace contains special character then do replace it with u201C~u201D in folder name.
If namespace is http://abc.com/XI/FileToFile then folder name should be replace with httpabc.comXI~FileToFile
Export schema from the ESR and save it in folder u201CFu201D with name <<RootElementOfMessageType>>.xsd. So in this case it is MT_File_Sender.xsd

Using Convert to handle NULL values for empty Strings ""
After having had the problem with null values not being returned as nulls and reading some suggestion solution I added a converter to my application.
<converter>
<converter-id>NullStringConverter</converter-id>
<converter-for-class>java.lang.String</converter-for-class>
<converter-class>com.j2anywhere.addressbookserver.web.NullStringConverter</converter-class>
</converter>
...I then implemented it as follows:
public String getAsString(FacesContext context, UIComponent component, Object object)
System.out.println("Converting to String : "+object);
if (object == null)
System.out.println("READING null");
return "NULL";
else
if (((String)object).equals(""))
System.out.println("READING null (Second Check)");
return null;
else
return object.toString();
public Object getAsObject(FacesContext context, UIComponent component, String value)
System.out.println("Converting to Object: "+value+"-"+value.trim().length());
if (value.trim().length()==0 || value.equals("NULL"))
System.out.println("WRITING null");
return null;
else
return value.toUpperCase();
...I can see that it is converting my values, however the object to which the inputText fields are bound are still set to empty strings ""
<h:inputText size="50" value="#{addressBookController.contactDetails.information}" converter="NullStringConverter"/>Also when reading the object values any nulls are already converted to empty strings before ariving at the converter. It seems that there is a default converter handling string values.
How can I resolve this problem as set nulls when the input value is an empty string other then checking every string in my class individually. I would really hate to pollute my object model with empty string tests.
Thanks in advance
Edited by: j2anywhere.com on Oct 19, 2008 9:06 AMI changed my converter as suggested :
public Object getAsObject(FacesContext context, UIComponent component, String value)
if (value == null || value.trim().length() == 0)
if (component instanceof EditableValueHolder)
System.out.println("SUBMITTED VALUE SET TO NULL");
((EditableValueHolder) component).setSubmittedValue(null);
else
System.out.println("COMPONENT :"+component.getClass().getName());
System.out.println("Converting to Object: " + value + "< to " + null);
return null;
System.out.println("Converting to Object: " + value + "< to " + value);
return value;
}which produces the following output :
SUBMITTED VALUE SET TO NULL
Converting to Object: < to null
Info : The INFO line however comes from my controller object where I print out the set value :
package com.simple;
import java.util.ArrayList;
import java.util.List;
public class Controller
private String information;
/** Creates a new instance of Controller */
public Controller()
System.out.println("Createing Controller");
information = "Constructed";
public String process()
System.out.println("Info : "+getInformation());
return "processed";
public String reset()
setInformation("Re-Constructed");
System.out.println("Info : "+getInformation());
return "processed";
public String setNull()
setInformation(null);
System.out.println("Info : "+getInformation());
return "processed";
public String getInformation()
return information;
public void setInformation(String information)
this.information = information;

Cannot set selectOneChoice value during reload (value auto become null)
Dear all,
I have a problem that getting null value in the SelectOneChoice field in a table binded to
a view object. If I change that SelectOneChoice to inputText, it works perfectly. The details
of the situation is described as follows:
I've binded a view objects with 8 attributes to a af:table, then I manually change
2 of the inputText fields inside 'Column' fields of the table to inputlistofvalue and
selectOneChoice. The code is as follow:
<af:column sortProperty="#{bindings.OpenBalanceVO1.hints.AcNo.name}"
sortable="false"
headerText="#{bindings.OpenBalanceVO1.hints.AcNo.label}"
id="c1" width="180"

id="it2" autoSubmit="false"
partialTriggers="cb1 cb2">
<f:selectItems value="#{loginInfo.activeCurrencies}" id="currenciesList"/>
</af:selectOneChoice>
</af:column>
And I have binded the returnPopupListener to returnListerner event handler to automatically
set the Currency field (2nd field) after the user chose the Account field (1st field) from
the input list of value:
public void returnListener(ReturnPopupEvent returnPopupEvent) {
RichInputListOfValues lovField = (RichInputListOfValues)returnPopupEvent.getSource();
ListOfValuesModel lovModel = lovField.getModel();
CollectionModel collectionModel = lovModel.getTableModel().getCollectionModel();
JUCtrlHierBinding treeBinding = (JUCtrlHierBinding)collectionModel.getWrappedData();
RowKeySet rks = (RowKeySet)returnPopupEvent.getReturnValue();
List tableRowKey = (List)rks.iterator().next();
DCIteratorBinding dciter = treeBinding.getDCIteratorBinding();
Key key = (Key)tableRowKey.get(0);
Row row = dciter.findRowByKeyString(key.toStringFormat(true));
DCBindingContainer bc = getBindingContainer();
DCIteratorBinding it2 = bc.findIteratorBinding("OpenBalanceVO1Iterator");
OpenBalanceVOImpl viewObject = (OpenBalanceVOImpl)it2.getViewObject();
FacesContext fctx = FacesContext.getCurrentInstance();
ExpressionFactory elFactory = fctx.getApplication().getExpressionFactory();
ValueExpression ve = elFactory.createValueExpression(fctx.getELContext(), "#{loginInfo}", LoginInfo.class);
LoginInfo loginInfo = (LoginInfo)ve.getValue(fctx.getELContext());
System.out.println("Return place: search date:" + loginInfo.getSearchDate());
Row newRow = viewObject.createRow();
String selectedAcNo = row.getAttribute("AcNo").toString();
String selectedCurrency = row.getAttribute("CurrencyCode").toString();
newRow.setAttribute("AcNo", selectedAcNo);
newRow.setAttribute("CurrencyCode",selectedCurrency);
newRow.setAttribute("OpenBal", 300);
newRow.setAttribute("AvailBal", 200);
newRow.setAttribute("CreateDate", new Date());
newRow.setAttribute("EffectiveDate", loginInfo.getSearchDate());
newRow.setAttribute("LockStatus", "N");
viewObject.insertRowAtRangeIndex(rowIndex, newRow);
The problem occurs when I use a 'createInsert' button to create a new row in the table,
and then choose a value from the inputListOfValues. The new row refresh and get the value
I chose in the first column in the new row. But the second column (currency field) is left
as empty (null value). If I change the second column frmo selectOneChoice to inputText,
the correct Currency value (e.g. "HKD" or "USD") can be shown. So I wonder if there is any
additional tricks in order to set the selectOneChoice value during refresh.
Additionally I have tried to check the state of the view object attributes during the refresh
lifecycle and found that the following reload method (else place) is being reached 3 times after I click
the 'ok' button in the popup up in the inputListOfValue.
public void beforePhase(PagePhaseEvent event) {
//System.out.println("i am here inside backing bean : before phrase 1 phrase ID:" + event.getPhaseId());
if (event.getPhaseId() == Lifecycle.PREPARE_MODEL_ID) {
if (!isPostback()) {
} else {
System.out.println("Post Back on Page Load!");
DCIteratorBinding it2 = bc.findIteratorBinding("OpenBalanceVO1Iterator");
OpenBalanceVOImpl viewObject = (OpenBalanceVOImpl)it2.getViewObject();
RowSetIterator iterator = viewObject.createRowSetIterator(null);
iterator.reset();
while (iterator.hasNext()) {
//Row row = viewObject.getCurrentRow();
Row row = iterator.next();
System.out.print("Account:" + row.getAttribute("AcNo"));
System.out.print(",AvailBal:" + row.getAttribute("AvailBal"));
System.out.print(",OpenBal:" + row.getAttribute("OpenBal"));
System.out.print(",CurrencyCode:" + row.getAttribute("CurrencyCode"));
System.out.print(",EffectiveDate:" + row.getAttribute("EffectiveDate"));
System.out.print(",UserCreate:" + row.getAttribute("UserCreate"));
System.out.println("");
if (row.getAttribute("UserCreate").toString().equals("<current user>")) {
System.out.println("Match <current user> in preload");
//row.setAttribute("CurrencyCode", "USD");
System.out.println("end of reload");
During the 1st time, the CurrencyCode field was set currently, but then in the 2nd and 3rd
times, it's value suddenly changed to 'null'. If I use inputText, all the 3 times currencyCode
field is showing correctly without the null issue.
Anyone can kindly give me some hints? Thanks a lot!!!Dear all,

LoginInfo loginInfo = (LoginInfo)ve.getValue(fctx.getELContext());
System.out.println("Return place: search date:" + loginInfo.getSearchDate());
Row newRow = viewObject.createRow();
String selectedAcNo = row.getAttribute("AcNo").toString();
String selectedCurrency = row.getAttribute("CurrencyCode").toString();
newRow.setAttribute("AcNo", selectedAcNo);
newRow.setAttribute("CurrencyCode",selectedCurrency);
newRow.setAttribute("OpenBal", 300);
newRow.setAttribute("AvailBal", 200);
newRow.setAttribute("CreateDate", new Date());
newRow.setAttribute("EffectiveDate", loginInfo.getSearchDate());
newRow.setAttribute("LockStatus", "N");
viewObject.insertRowAtRangeIndex(rowIndex, newRow);
The problem occurs when I use a 'createInsert' button to create a new row in the table,
and then choose a value from the inputListOfValues. The new row refresh and get the value
I chose in the first column in the new row. But the second column (currency field) is left
as empty (null value). If I change the second column frmo selectOneChoice to inputText,
the correct Currency value (e.g. "HKD" or "USD") can be shown. So I wonder if there is any
additional tricks in order to set the selectOneChoice value during refresh.
Additionally I have tried to check the state of the view object attributes during the refresh
lifecycle and found that the following reload method (else place) is being reached 3 times after I click
the 'ok' button in the popup up in the inputListOfValue.
public void beforePhase(PagePhaseEvent event) {
//System.out.println("i am here inside backing bean : before phrase 1 phrase ID:" + event.getPhaseId());
if (event.getPhaseId() == Lifecycle.PREPARE_MODEL_ID) {
if (!isPostback()) {
} else {
System.out.println("Post Back on Page Load!");
DCIteratorBinding it2 = bc.findIteratorBinding("OpenBalanceVO1Iterator");
OpenBalanceVOImpl viewObject = (OpenBalanceVOImpl)it2.getViewObject();
RowSetIterator iterator = viewObject.createRowSetIterator(null);
iterator.reset();
while (iterator.hasNext()) {
//Row row = viewObject.getCurrentRow();
Row row = iterator.next();
System.out.print("Account:" + row.getAttribute("AcNo"));
System.out.print(",AvailBal:" + row.getAttribute("AvailBal"));
System.out.print(",OpenBal:" + row.getAttribute("OpenBal"));
System.out.print(",CurrencyCode:" + row.getAttribute("CurrencyCode"));
System.out.print(",EffectiveDate:" + row.getAttribute("EffectiveDate"));
System.out.print(",UserCreate:" + row.getAttribute("UserCreate"));
System.out.println("");
if (row.getAttribute("UserCreate").toString().equals("<current user>")) {
System.out.println("Match <current user> in preload");
//row.setAttribute("CurrencyCode", "USD");
System.out.println("end of reload");
During the 1st time, the CurrencyCode field was set currently, but then in the 2nd and 3rd
times, it's value suddenly changed to 'null'. If I use inputText, all the 3 times currencyCode
field is showing correctly without the null issue.
Anyone can kindly give me some hints? Thanks a lot!!! -
XML validation in sender file adapter
Hi
I am using FCC on the sender file adapter ....i need to make sure that one of the fields should always be integer else the sender adapter should give error
Can i use xml validation with FCC on the sender file adapter?Hi Hema,
As per understanding you need to check one or few fields value is integer or not.
You can achieve in 2 ways :
Case1:Using inbuilt xml validation options.
For 7.11 and below
1)In ESR/Message type/Export the xsd to local machine.
2)Insert the xsd file in the below loc
/usr/sap/<sid>/DVEBMGS00/j2ee/cluster/server0/validation/schema/
<guid>/<namespace1>/<service_interface_name>/<namespace2>
<sid>: System ID of the server instance.
<guid>: The GUID of the SWCV.
<namespace1> : The namespace within which the service interface is defined.
<service_interface_name> : The name of the service interface.
<namespace2>
: The namespace of the Message Type used by the service interface. In many
instances, namespace1 and namespace2 are the same.
Italic path folders need to create by you.
For 7.3 and above
Michal's PI tips: XML validation - changes in 7.3
Case 2 :Handling using simple UDF.
Input-->UDF-->Output
try {
Integer.parseInt(input);
return input ;
catch(NumberFormatException e) {
throw new StreamTransformationException( "Input field value for xyz field "+input+"is not in integer format.Plz correct it");

Xml validation ---- file system of PI ???
hi all ,
i read the xml validation concept of PI7.1 . iam unable to find any practical explanation about the following
"To validate the structure of a PI message payload, you should export the schemas from the ESR and save them in the file system of PI. "
save them in the file system of pi ... where does this mean to be stored ?.
will it be necessary for both the ADAPTER ENGINE & INTEG ENGINE VALIDATION?
Please give any other important aspect of this validation concept which u came across during ur practical implementation
THANKS IN ADVANCEHi Netaji,
Validating the XML documents is a new feature introduced in SAP NetWeaver Process Integration 7.1. The validation can be performed at two different locations - Integration Server or the Adapter Engine. Validations can be done in both synchronous and asynchronous operations.
In the synchronous scenario or using an adapter that can handle synchronous messages (e.g. HTTP and SOAP adapters), when a validation error occurs, the error message will be returned to the sender. In the case of asynchronous scenarios (e.g. file adapter), the error message will be logged to the SXI_MONITOR when the validation is done in the Integration Server or to the Runtime Workbench (RWB) when the validation is done in the Adapter Engine. In both cases, the messaging will be terminated with error.
Both Integration Server and Adapter Engine can be used for validating XML from the sender. However, only the Integration Server can be used to validate the XML when sending to the receiver. The XML validation configurations are done in either the Sender Agreement or the Receiver Agreement.
In the current release, as of PI 7.1, the XML schema (or XSD) to be used for the XML validation has to reside in a file directory under the JEE. The XSD file has to be explicitly copied into a specific directory, depending on where the validation is to be performed.

XML validation against registered XSD
I have registered XSD into oracle database, while validating xml against this xsd I got stuck with non-mandatory tags.
Below is the tag-XSD structure:
Status field as String:
<xs:element name="Status" nillable="false"> <xs:annotation> <xs:documentation>Values are 'N' or 'E'</xs:documentation>
</xs:annotation>
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:maxLength value="1"/>
</xs:restriction>
</xs:simpleType>
</xs:element>
idnumber tag field as Integer:
<xs:element name="idnumber" type="xs:int" nillable="false">
<xs:annotation>
<xs:documentation>id value </xs:documentation>
</xs:annotation>
</xs:element>
As status tag is of string type and I have mentioned it as nillable = "False", but even though when I am passing this tag as <status/>, then also its validating xml.... but as i mentioned nillable property as false then it should not validate it ..... please correct me if i m wrong..
In case of idnumber tag it is of int type. In this case <idnumber/> will not work in either case even it is nillable = true or false. Means we cannt pass null values in integer field..... right?
Please suggest me how to make tag of string datatype as not nillable.
Is there any significance of using nillable = "false" in int datatype tag. Means if we want to make it as optional then need to mention it as minoccurs = 0..... is it correct?
Requirement is simple:
Just want to make some tag as optional and some as mandatory, tag can be of integer or string type.
Thanks in advance.....

The nillable attribute doesn't work that way. It's easy to look that up in any tutorial.
nillable = "true" means you allow the element to have a NULL content (different from empty string) by specifying an explicit null attribute :
<Status xsi:nil="true" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/>nillable = "false" is the default behaviour.

Requirement is simple:
Just want to make some tag as optional and some as mandatory, tag can be of integer or string type. You have to be careful about the vocabulary.
In my mind, an "optional" element means you can omit it entirely in the instance document (minOccurs="0"), whereas an empty element means the start tag and end tag are there but with no content.
There are multiple ways to allow for empty or non-empty elements.
e.g. for a non-empty string :
<xs:minLength value="1"/>or, as in your example, if the content is actually constrained to a list of values, use enumerations.
xs:int datatype doesn't allow empty values (unless you use xsi:nil).
A possible solution is to build a new type by unioning (xs:union) an xs:int and an empty string type. -
SAX Parser XML Validation Problems
Hi,
I’m having problems getting an xml document to validate within Weblogic 8.1. I am trying to parse a document that references both a dtd and xsd. Both the schema and dtd reference need to be substituted so they use local paths. I specify the schema the parser should use and have created an entityResolver to change the dtd reference.
When this runs as a standalone app from eclipse the file parses and validates without a problem. When deployed to the app server the process seems to be unable read the contents of the dtd. Its not that it cannot find the file (no FileNotFoundException is thrown but this can be created if I delete the dtd) rather it seems to find no declared elements.
Initial thought was that the code didn’t have access to read the dtd from its location on disk, to check I moved the dtd to within the deployed war and reference as a resource. The problem still persists.
Code Snippet:
boolean isValid = false;
try {
// Create and configure factory
SAXParserFactory factory = SAXParserFactoryImpl.newInstance();
factory.setValidating(true);
factory.setNamespaceAware(true);
// To be notified of validation errors in the XML document,
// add a custom error handler to the document builder
PIMSFeedFileValidationHandler handler
= new PIMSFeedFileValidationHandler();
// Create and Configure Parser
SAXParser parser = factory.newSAXParser();
parser.setProperty(JAXP_SCHEMA_LANGUAGE, W3C_XML_SCHEMA);
parser.setProperty(NAMESPACE_PROPERTY_KEY, getSchemaFilePath());
// Set reader with entityResolver for dtd
XMLReader xmlReader = parser.getXMLReader();
xmlReader.setEntityResolver(new SAXEntityResolver(this.dtdPath));
// convert file to URL, as it is a remote file
URL url = super.getFile().toURL();
// Open an input stream and parse
InputStream is = url.openStream();
xmlReader.setErrorHandler(handler);
xmlReader.parse(new InputSource(is));
is.close();
// get the result of parsing the document by checking the
// errorhandler's isValid property
isValid = handler.isValid();
if (!isValid) {
LOGGER.warn(handler.getMessage());
LOGGER.debug("XML file is valid XML? " + isValid);
} catch (ParserConfigurationException e) {
LOGGER.error("Error parsing file", e);
} catch (SAXException e) {
LOGGER.error("Error parsing file", e);
} catch (IOException e) {
throw new FeedException(e);
return isValid;

Has anybody seen this behavior before with weblogic and if so how have you resolved the issue.
Thanks in Advance
AdamHi David,
I have checked the ejb-jar.xml file and there is no duplicate values in it and the other things is that the same application is been deployed on OAS 10G and websphere and its working fine. In the forum someone has replied to a similar problem that there is bug in Weblogic 10.3 and its CR no 376292. I am not sure about it, does anyone any information about it.
Thanks and Regards

Want to retrieve null value from xml?
i m writing this code to get the tag name and values from xml file.
Now the problem is that
if my xml file contain any tag whose value is not defined like
<root>
<firsttag>first</firsttag>
<Second></Second><Third>third</Third>
</root>
Now look if second tag doesnt contain anything ,then i want to add "null" to vector,but it throws null pointer exception because second tag is empty.
Vector<String> CSWFinfo = new Vector<String>();
try {
DocumentBuilderFactory factory = DocumentBuilderFactory
.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document doc = builder.parse(new File(xml));
Element root = doc.getDocumentElement();
NodeList node = root.getChildNodes();
for (int i = 0; i < node.getLength(); i++) {
Node currentNode = node.item(i);
if (isTextNode(currentNode))
continue;
CSWFinfo.addElement(currentNode.getNodeName());
if (null != currentNode.getFirstChild().getNodeValue()) {
CSWFinfo.addElement(currentNode.getFirstChild()
.getNodeValue());
} else {
CSWFinfo.addElement("null");
}//end of for loop block
System.out.println(CSWFinfo);
} catch (Exception e) {
e.printStackTrace();
// TODO: handle exception
}I am using dom parser .
Can any one know how to do it????
Edited by: chauhan2003 on 16 Jun, 2008 12:06 PMAre you sure that all currentNode have a firstChild ????
If your node has no value, it has no child
So i 'd change code to like look something like:
if (currentNode.getFirstChild() != null) {
CSWFinfo.addElement(currentNode.getFirstChild().getNodeValue());
} else {
CSWFinfo.addElement("null");
}
