Customize xml/xsd validation messages

Hi,everyone,
I've been validating XML files with a XSD (Schema) and it works ok. But my client wants to see customized messages for the validation exceptions.
I would like to know if there is a "good way" (best or recommended practice) to, maybe, add those messages to the XSD (when the validation xsd:pattern is not passed) and expose them when a validation pattern is not fullfiled.
Thanks for any help, hints or tricks!

Doc Import Param to suppress XML import validation message

Hi,
I'm running a script where the first part is to import an xml document, then to make some changes to the imported xml.
Problem is, the xml may not always be valid. If it isn't I would like to still make the changes regardless.
Unfortunately, my code is not running as I end up with "Validation of XML file failed. Continue? " prompt.
Can I somehow suppress this ? or is there a way to send the OK key hit - so my code can just continue without requiring any user interaction ?
var importParams = GetImportDefaultParams();
                         i=GetPropIndex(importParams,Constants.FS_ImportAsType);
                        importParams[i].propVal.ival=Constants.FV_TYPE_XML;
                         i=GetPropIndex(importParams,Constants.FS_FileIsXmlDoc);
                        importParams[i].propVal.ival=Constants.FV_DoOK;
                        i=GetPropIndex(importParams,Constants.FS_AlertUserAboutFailure);
                        importParams[i].propVal.ival=0;
                         i=GetPropIndex(importParams,Constants.FS_DontNotifyAPIClients);
                        importParams[i].propVal.ival=1;
                       // var importParams = GetImportDefaultParams();
                        i=GetPropIndex(importParams,Constants.FS_HowToImport);
                        importParams[i].propVal.ival=Constants.FV_DoByCopy;
                        var returnParams = new PropVals() ;
                alert("importing");
                        doc.Import (doc.TextSelection.end , filename, importParams, returnParams);
             app.ActiveDoc = doc;

Hi,
Have you already tried to suppress the alert?
There is an example of this in the FrameMaker installation.

XSD VALIDATION IN ABAP PROGRAM

Hi,
I have a requirement where in a report i am picking xml file from the presentation server (desktop) and then i am parsing the xml file using FM "SMUM_XML_PARSE" (first i use FM SCMS_BINARY_TO_XSTRING and then SMUM_XML_PARSE). after using the function SMUM_XML_PARSE i get the xml data in my internal table and then my report uses that data for some processing. This all is working fine .
My issue is that how do i do a XSD VALIDATION for the xml file that i am reading . I would have liked to do a xsd validation after i import the xml file and throw error if the xml file is not as per its xsd.As i am not using any middleware technology like XI/ WTX which have XSD validation functionality i am not sure how to achieve this in abap program.

Hi,
I think you're right, iXML can only validate DTD via its if_ixml_parser->set_validating method (you can find this information in SAP SDN article "ABAP XML Mapping", as of release 6.10, I couldn't find any other reference saying that xsi:noNamespaceSchemaLocation is supported since then).
By looking at SDN, I saw an external link about XSD to DTD conversion via XSLT (http://crism.maden.org/consulting/pub/xsl/xsd2dtd.xsl), but I don't have any idea if it works. On another thread, people used OS command to do XML/XSD validation, but didn't describe what they ran exactly (anyway, that means using any external tool).

I see you problem but the strictness of XML is essential. One has learned from of HTML - each browser trying to fix and show the stuff in spite of, say, invalid tags. To blow up at the first error is a compliant (and maybe desired?) behaviour.

The cause of the error is there being three maxOccurs attributes set to "9999" in the schema. All you can do is to change "9999" to a lesser value or "unbounded". This is a bug in J2SE, which is unlikely to be fixed in the foreseeable future.

DTD and XSD Validation for xml file

hi kindly reply to this mail guru'ssss
i am facing a problem in parising a xml file against dtd and xsd.
i have the dtd which contains only enitities that can be present in the xml file and the xsd file for validation against elements and attribute.
when DTD is present then it is throwing errors like the elements should be declared.
when i take out the doctype line and validate against schema its throwing the error that particular entity is not found or declared.

XML Schematron Validation Warning Message

Hi I have created an XML Schematron validation for my process, I'm getting the following warning in the process
Warning: Schematron file has invalid context "/imp1:WMWROOT/imp1:WMWDATA/imp1:WMFWUpload/imp1:Shipments/imp1:Shipment", validation may not happen properly. Please verify file manually.
I have verified the ".sch" file thoroughly there is no mistake in the namespace or paths . On testing this works perfectly well. I do not know what is causing this warning.
Could some one please help.
Thanks in advance
Nikhil

Warnings you can skip, having said that check the format of your file, use xmlspy IDE to check the file format.

FTP Adapter XSD Validation

Hi All,
Oracle InterConnect 10.1.2
Oracle Adapters (AQ,FTP) using XSD
FTP Adapter on local filesystem
In the FTP Adapter, Is there anyway to validate the XML content against the XSD?
The validation is happening at the common view when i use the "Validate XML" check box while creating the event in iStudio. However this option does not appear while configuring the FTP adapter in iStudio. I would like FTP adapter to reject the XML file if the XSD validation fails and move the file to the exception folder.
Objective: XSD should perform datatype, datasize and format validations.
Thanks,
Sherry

Can anyone let me know how to enforce the XSD validation in the adapter. As of now only the structure of the message is being checked.

Adapter Engine XML Schema Validation Error Surpression

We recently developed a number of web services that are called by 3rd parties outside our network. The web service request once made is picked up by a Web Dispatcher which then forwards the request to the de-central adapter. Both of these components reside within within a DMZ.
We have, as an additional security measure made use of the new Adapter Engine XML Schema validation available with PI 7.1, to ensure that the payload of incomming messages is checked to ensure that it is a known structure.
Now here is my problem, we recently had these services penetration tested by a 3rd party to ensure that they were secure and whilst the report was very good showing no major weaknesses they did pickup on a couple of items including that the fact that if the XSD to be used during payload message validation cannot be found an 'ADAPTER.JAVA_EXCEPTION' is returned to the web service consumer that highlights the path details of where the XSD should be (but could not be found).
This was viewed as useful to an attacker for a number of reasons:
1. Feedback in SQL injection attempts via verbatim DB error messages greatly improves attacker efficiency
2. Path information is useful to the attacker for OS fingerprinting, directory traversal attempts
3. Other miscellaneous stack trace information is useful to an attacker to understand how the application works
Is there anyway this can be surpressed so that the adapter does not show this information in the returned error message - see example message below ?

Hi,
We are having the same problem, so you are not alone.
I had an extensive call with Azure premium support and we where able to determine that:
- Nothing is missing or in the wrong place in my exported .xml file.
- Any changes to the VNET's using the web gui interface of https://manage.windowsazure.com is not possible when you have dns servers and use an gateway
- You can download the .xml configuration file of the network and make manual changes to it, then import it again , to add/remove dns servers and or subnet's.
I am currently waiting for an solution, i have let them lower the urgency from A to B (because i can make changes trough xml) and responded to the next support contact (saying he will continue with the issue) that the problems seems to be with azure and
he should speak with the previous person helping me. I have not heard from Azure support since.

I hope microsoft is going to resolve this soon, as i do not want to edit my xml for little things like adding a subnet all the time. I have requested an status update in the issue.
Should anyone have more information on this, please share it here.

XML Schema validation Error

Hi,
Have a scenerio in which consecutive mapping needs to be done.The first mapping is a Java Mapping in which XML schema validation needs to be done.
If XML Schema validation is sucessful(Mapping 1),then graphical message mapping(MM_Entry) needs to be performed.
I have uploded a jar file in imported Archives which contains
1)Schema file(inputSchema.xsd): This is an XSD file which is generated in XI....XSD fomat of Source message type
2) The java Class file
Following are few lines of code for better idea:
public class SAXParser implements StreamTransformation {
public void execute(InputStream input, OutputStream output) throws StreamTransformationException {
SAXParserFactory saxParserFactory = SAXParserFactory.newInstance();
InputStream mySchema = this.getClass().getClassLoader().getResourceAsStream("inputSchema.xsd");
SAXParser saxParser = saxParserFactory.newSAXParser();
saxParser.setProperty("http://java.sun.com/xml/jaxp/properties/schemaLanguage", "http://www.w3.org/2001/XMLSchema");
saxParser.setProperty("http://java.sun.com/xml/jaxp/properties/schemaSource",mySchema);
saxParser.parse(input, new HandlerBase());
After above step(parsing),input is copied to output and streams are closed as follows:
byte[] buf = new byte[4096];
for(int len=-1;(len=input.read(buf))!=-1;)
output.write(buf,0,len);
input.close();
output.close();
After sending correct source message from input ,i am getting following error:
Runtime exception occurred during execution of application mapping program com/sap/xi/tf/_MM_Entry_: com.sap.aii.utilxi.misc.api.BaseRuntimeException; Parsing an empty source. Root element expected!

Daniel,
As I've said, I've used it successfully in PI 7.0 SP10.
You're right about documentation, it says that by default, Java 1.4.2 mark() and reset() methods of InputStream class are not fully implemented (mark() would do nothing and reset() would always throw an IOException). And that would be the expected behavior...
...unless the SAP developers have extended the InputStream class to include actual implementatios to the mark() and reset() methods.
I'm not saying that they have, but it would be possible, wouldn't it?
It does work, after all...
Regards,
Henrique.

XML Schema Validations in JDK1.4?

Hi,
The below code errors out when run on JDK1.4-
SchemaFactory schemaFactory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
Schema schemaXSD = schemaFactory.newSchema(new File("C:\\TestSchema.xsd"));
Validator validator = schemaXSD.newValidator();
SAXSource source = new SAXSource(new InputSource("D:\\test.xml"));
validator.validate(source);
The exception is-
Exception Message=http://www.w3.org/2001/XMLSchema
java.lang.IllegalArgumentException: http://www.w3.org/2001/XMLSchema
at javax.xml.validation.SchemaFactory.newInstance(Unknown Source)
I also tried by adding the JAR file xml-apis.jar. But, it gives the same Exception.
The above code runs fine on JDK1.5 but the requirement of my project is to use only JDK1.4 and run it on UNIX platform.
Is there any way that this can work with JDK1.4?
Otherwise are there any other JAVA API in JDK1.4 for performing XML Schema Validations?
Thanks,
Tanu

Thanks DrClap.
Does that mean JDK1.4 does not have any inbuilt classes for Schema Validations?
Which parser should I use?
Thanks,
Tanu

Why XSD Validation Is used and How

Hi All
Please explaim why we use XSD validation and how it is done.
Regar

Hi Nidhi,
>>I still did not unserstand that what is the purpose of using XSD vilidation for sender soap scenario.
May be you shoudl have written this in the first place that you need to know why XSD validation for SOAP sender scenarios
Now have you created a SOAP scenario in PI and have given the wsdl to some external client? If yes then you may not be required to use the XSD validation option, because you have given the source structure used in PI in the wsdl file itself.
Now think like you have not provided the wsdl file and the source side is manually creating the XML that need to be sent to PI. there are chances that the mandatory fields may be missed or some other mismatch in structure can happen. If you don't go for XSD validation in source side there are chances that you message mapping may fail. So to avoid this you can use the XSD Validation, where you are validating the XML structure (which is sent to PI) with XSD schema (which is used in PI) amd if any mismatch found then it can fail before mapping

ADAPTER.JAVA_EXCEPTION - java.lang.Exception: no valid message format obje

Hi experts,
we have a problem when we call a web service PI (release 7.01 , SP 10), from legacy system : the PI system return this message : ADAPTER.JAVA_EXCEPTION ; - java.lang.Exception: no valid message format object found
For to test this scenario we use soapUI tool.
I tried the URL (... /XISOAPAdapter/HelperServlet?action=FindChannel ...) in IE and got the following response :
<?xml version="1.0"; ?>
- <s:ChannelInfo xmlns:s="http://sap.com/xi/WebService/xi30">

Did you check the page no 14 of the document which has the same problem - in problem analysis it has mentioned that check the URL as well as proxy setting of internet browser.
3) Try to create the ID objects manually (Sender Channel and Sender Agreement).....when we use the wizard a * gets introduced in the unfilled (unused) fields (party etc) ....however when manually created the unused fields are left blank.
4) Check if all the ID objects are available in SXI_CACHE.

JAXP API provides no way to enable XML Schema validation mode

I am evaluating XDK 9.2.0.5.0 for Java and have encountered another
problem with XML Schema support when using the JAXP API.
Using the classes in oracle.xml.jaxp.*, it appears to be impossible to
enable XML Schema validation mode. I can set the schema object, but
the parser does not use it for validation.
If I use DOMParser directly, I can call the setValidationMode(int)
method to turn on schema validation mode. There is no equivalient
means to enable XML Schema validation when using the JAXP API.
Test case for JAXP API:
=== begin OracleJAXPSchemaTest.java ======
package dfranklin;
import java.io.*;
import javax.xml.parsers.*;
import javax.xml.transform.*;
import javax.xml.transform.dom.*;
import javax.xml.transform.stream.*;
import oracle.xml.parser.schema.XMLSchema;
import oracle.xml.parser.schema.XSDBuilder;
import org.w3c.dom.*;
import org.xml.sax.*;
public class OracleJAXPSchemaTest
private final static String xsd = ""
+"<xsd:schema xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" targetNamespace=\"urn:dfranklin:test\">"
+" <xsd:element name=\"amount\" type=\"xsd:integer\"/>"
+"</xsd:schema>";
private final static String xml =
"<amount xmlns=\"urn:dfranklin:test\">1</amount>";
public static void main(String[] args)
throws Exception
System.setProperty("javax.xml.parsers.DocumentBuilderFactory",
          "oracle.xml.jaxp.JXDocumentBuilderFactory");
new OracleJAXPSchemaTest().run();
public void run()
throws Exception
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setValidating(true);
dbf.setNamespaceAware(true);
XMLSchema xmlSchema = buildXMLSchema(new StringReader(xsd));
dbf.setAttribute("oracle.xml.parser.XMLParser.SchemaObject",
          xmlSchema);
DocumentBuilder docbldr = dbf.newDocumentBuilder();
Document doc = docbldr.parse(new InputSource(new StringReader(xml)));
print(doc);
private XMLSchema buildXMLSchema(Reader xsdin)
throws Exception
XSDBuilder xsdBuilder = new XSDBuilder();
XMLSchema xmlSchema = (XMLSchema)xsdBuilder.build(xsdin, null);
return xmlSchema;
private void print(Document doc)
throws
javax.xml.transform.TransformerConfigurationException,
javax.xml.transform.TransformerException
Transformer xformer = TransformerFactory.newInstance().newTransformer();
xformer.transform(new DOMSource(doc), new StreamResult(System.out));
System.out.println();
=== end OracleJAXPSchemaTest.java ======
Running that program:
java dfranklin.OracleJAXPSchemaTest
produces this output
Exception in thread "main" oracle.xml.parser.v2.XMLParseException: Element 'amount' used but not declared.
at oracle.xml.parser.v2.XMLError.flushErrors(XMLError.java:148)
at oracle.xml.parser.v2.NonValidatingParser.parseDocument(NonValidatingParser.java:269)

at oracle.xml.jaxp.JXDocumentBuilder.parse(JXDocumentBuilder.java:96)
at dfranklin.OracleJAXPSchemaTest.run(OracleJAXPSchemaTest.java:40)
at dfranklin.OracleJAXPSchemaTest.main(OracleJAXPSchemaTest.java:27)
This shows that the parser is not using the XML Schema to validate the
document. I think it's expecting to find a DTD.
Here is the equivalent program using DOMParser directly, and setting
validation mode to SCHEMA_VALIDATION.
=== begin OracleParserTest.java ====
package dfranklin;

+"</xsd:schema>";
private final static String xml =
"<amount xmlns=\"urn:dfranklin:test\">1</amount>";
public static void main(String[] args)
throws Exception
new OracleParserTest().run();
public void run()
throws Exception
DOMParser dp = new DOMParser();
XMLSchema xmlSchema = buildXMLSchema(new StringReader(xsd));
dp.setXMLSchema(xmlSchema);
dp.setValidationMode(XMLParser.SCHEMA_VALIDATION);
dp.parse(new InputSource(new StringReader(xml)));
Document doc = dp.getDocument();
print(doc);
private XMLSchema buildXMLSchema(Reader xsdin)
throws Exception
XSDBuilder xsdBuilder = new XSDBuilder();
XMLSchema xmlSchema = (XMLSchema)xsdBuilder.build(xsdin, null);
return xmlSchema;
private void print(Document doc)
throws
javax.xml.transform.TransformerConfigurationException,
javax.xml.transform.TransformerException
Transformer xformer = TransformerFactory.newInstance().newTransformer();
xformer.transform(new DOMSource(doc), new StreamResult(System.out));
System.out.println();
=== end OracleParserTest.java ====
Running that program
java dfranklin.OracleParserTest
produces this output
<?xml version = '1.0'?>
<amount xmlns="urn:dfranklin:test">1</amount>
In this case, the parser has validated the document.
I also tried this with version 10.1.0.0.0 beta, and got the same
error.

Thanks for posting that. I tried that code and still got my problem. The big difference is that I'm reading a group of XML files each of which uses a large number of schema files. There are over 50 schema files organized so they can be included as needed. Each of the XML files has a noNamespaceSchemaLocation attribute specifying one of the ten top schma files, that includes many others.
However, I did solve the problem. I added one line --
       saxb.setFeature( "http://apache.org/xml/features/validation/schema",
                true);
        // next line is new
        saxb.setProperty( JAXPConstants.JAXP_SCHEMA_LANGUAGE,
                JAXPConstants.W3C_XML_SCHEMA );after the setFeature to turn on schema validation.
(It needs an import org.apache.xerces.jaxp.JAXPConstants; statement.)
Note:With the feature set to true and the setProperty commented out, the EntityResolver is called at construction tiem, and for each schema file, but each element is flagged as needing to be declared.
With the feature commented out, and the setProperty in place, the EntityResolver is not called, and there is no validation performed. (I added invalid content to one of the files and there were no errors listed.)
With both the setFeature and the setProperty in place, however, I get the calls from the EntityResolver indicating that it is processing the schema files, and for the good files, I get no errror, but for the bad file, I get an error indicating a bad validation.
Now I can make the EntityResolver quiet and get what I wanted. Maybe there are other ways to do this, but I've got one that works. :-)
Thanks to all who have helped.

Xml schema validation problem

Hi All
How to tackle this xml schema validation problem
i am using the sample code provided by ORacle technet for xml
schema validation in the Oracle database(817).
The sample code works perfectly fine.
Sample as provided by http://otn.oracle.com/tech/xml/xdk_sample/archive/xdksample_093001.zip.
It works fine for normal xml files validated against
xml schema (xsd)
but in this case my validation is failing . Can you let me know why
I have this main schema
Comany.xsd
===========
<?xml version="1.0"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://www.company.org"
xmlns="http://www.company.org"
elementFormDefault="qualified">
<xsd:include schemaLocation="Person.xsd"/>
<xsd:include schemaLocation="Product.xsd"/>
<xsd:element name="Company">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="Person" type="PersonType" maxOccurs="unbounded"/>
<xsd:element name="Product" type="ProductType" maxOccurs="unbounded"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:schema>
================
which includes the following 2 schemas
Product.xsd
============
<?xml version="1.0"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified">
<xsd:complexType name="ProductType">
<xsd:sequence>
<xsd:element name="Type" type="xsd:string"/>
</xsd:sequence>
</xsd:complexType>
</xsd:schema>
==============
Person.xsd
===========
<?xml version="1.0"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified">
<xsd:complexType name="PersonType">
<xsd:sequence>
<xsd:element name="Name" type="xsd:string"/>
<xsd:element name="SSN" type="xsd:string"/>
</xsd:sequence>
</xsd:complexType>
</xsd:schema>
=================
now when i try to validate a xml file against Company.xsd
it throws an error saying unable to find Person.xsd.
no protocol error
Now where do i place these 2 schemas(.xsd files) Person & product
so that the java schemavalidation program running inside Oracle
database can locate these files

Hi Jinyu
This is the java code loaded in the database using loadjava called by a wrapper oracle stored procedure
import oracle.xml.parser.schema.*;
import oracle.xml.parser.v2.*;
import java.net.*;
import java.io.*;
import org.w3c.dom.*;
import java.util.*;
import oracle.sql.CHAR;
import java.sql.SQLException;
public class SchemaUtil
public static String validation(CHAR xml, CHAR xsd)
throws Exception
//Build Schema Object
XSDBuilder builder = new XSDBuilder();
byte [] docbytes = xsd.getBytes();
ByteArrayInputStream in = new ByteArrayInputStream(docbytes);
XMLSchema schemadoc = (XMLSchema)builder.build(in,null);
//Parse the input XML document with Schema Validation
docbytes = xml.getBytes();
in = new ByteArrayInputStream(docbytes);
DOMParser dp = new DOMParser();
// Set Schema Object for Validation
dp.setXMLSchema(schemadoc);
dp.setValidationMode(XMLParser.SCHEMA_VALIDATION);
dp.setPreserveWhitespace (true);
StringWriter sw = new StringWriter();
dp.setErrorStream (new PrintWriter(sw));
try
dp.parse (in);
sw.write("The input XML parsed without errors.\n");
catch (XMLParseException pe)
sw.write("Parser Exception: " + pe.getMessage());
catch (Exception e)
sw.write("NonParserException: " + e.getMessage());
return sw.toString();
This is the code i used initially for validating a xml file against single xml schema (.xsd) file
In the above code could u tell how to specify the second schema validation code for the incoming xml.
say i create another Schemadoc for the 2nd xml schema.
something like this with another parameter(CHAR xsd1) passing to the method
byte [] docbytes1 = xsd1.getBytes();
ByteArrayInputStream in1 = new ByteArrayInputStream(docbytes1);
XMLSchema schemadoc1 = (XMLSchema)builder.build(in1,null);
DOMParser dp = new DOMParser();
How to set for the 2nd xml schema validation in the above code or can i combine 2 xml schemas.
How to go about it
