XML Validation on HTTP Adaptor

Hi,
We are implementing a HTTP sender channel on PI 7.11 and requires XML validation to be performed upon receiving. The validation is required to check if all the tags are closed and ended properly. Failing to do so, an error XML will be generated and subsequently send back to the sender.
There is a blog /people/william.li/blog/2009/03/19/adapter-user-module-for-http-adapter detailing the development of user module for HTTP channel but we remain clueless on how can we change it to suit our needs. The XML messages can be of different format (different XSD) thus we need to make this as generic as possible.
Ultimately the intention is to prevent XML to fail at later stage within PI and stopped the communication. Hope any experts out there can point us to the right direction.
Thanks in advance!
Regards,
Wai Xin

Hi,
Your error message are not displaying because u does not made Message-Resoucrce property file (Resource Bundle) when you make it .
give it entry in
struts-config.xml
<message-resources parameter="ApplicationResources" />
and
define key and corresponding error message to key in this ApplicationResources i.e
#Error Resources
label.search.ssNum=Plz Enter correct ssNum

Can anyone please point out why am I getting the error?
Thanks

Hi CarlSun,
Thanks for the reply. I have made the changes suggested by you.
I have few queries:
1. Can we use attribute "source" in the description tag?
     I have created a local html page and specified it in source attribute. but the Extension Manager CS6 did not render the local html page and displayed      the following:
     No description avaliable. Click the following link for more details.
     "http://www.abcd.html". Is it possible to display a local html page in Extension Manager CS6?
2. Can I display an image (png) in CDATA under description tag? If yes, then can you please guide me how can I do so?
3. As suggested in tech notes MXI file must include UTF-8 encoding as header (<?xml version="1.0" encoding="UTF-8"?>). The MXI I am using does      not have this header. Do I need to include the header?
Thanks

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="">

<SAP:P4 />
<SAP:AdditionalText>not used at the moment.</SAP:AdditionalText>
<SAP:Stack>System error occurred during XML validation</SAP:Stack>
<SAP:Retry>M</SAP:Retry>
</SAP:Error>
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:

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!
RR

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>

XML validation in WS adapter

          </ns:SystemFault>
     </detail>
</n0:Fault>
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,
Jörg

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");

Does anyone have any idea what the problem is?
Thank you,

To daft_davy:
1. Your XSD document is invalid: the xmlns attribute of schema documents must always have the following value: "http://www.w3.org/2001/XMLSchema"
All other values will result in the following validation error:
org.xml.sax.SAXParseException: s4s-elt-schema-ns: The namespace of element 'schema' must be from the schema namespace, 'http://www.w3.org/2001/XMLSchema'.
Your XSD should look like this:
<?xml version="1.0"?>
<xsd:schema targetNamespace="blah" xmlns:tns="blah" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:simpleType name="Status">
    <xsd:restriction base="xsd:string">
      <xsd:enumeration value="Unknown"/>
    </xsd:restriction>
</xsd:simpleType>
<xsd:element name="host">
    <xsd:complexType>
      <xsd:all>
        <xsd:element name="status" type="tns:Status"/>
      </xsd:all>
    </xsd:complexType>
</xsd:element>
</xsd:schema>2. Your XML document does not match the XSD schema (even if you use the one above) for the following reasons:
a) The root element of the XML document must be associated with the namespace defined by the targetNamespace attribute of the schema.
b) The "blah" namespace at the element <status> in the XML document has to be undeclared because there is no namespace declaration to this element in the schema document either. There are to ways to do this:
<host xmlns="blah">
<status xmlns="">Unknown</status>
</host>or:
<xxx:host xmlns:xxx="blah">
<status>Unknown</status>
</xxx:host>
To watertownjordan:
The namespace URI can be virtually any string, so you don't need to specify a valid URI to define a namespace.

Xml validation and transformation in a row: Possible?

Hi.
I'm working on a small tool that uses javax.xml.validation and javax.xml.transform (JDK 6) to perform validation and transformation of xml files in a row.
The problem is, the namespaces and reference to the xml schema required by the validator somehow prevent the transformation from extracting data from the xml file.
Here's the header I use in the xml file:
<tagWhatever
xmlns="http://www.myPlace.com"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.myPlace.com mySchema.xsd">To sum it up, with the namespace declaration within the xml I can validate but not transform, and without the declaration, I can transform but not validate.
Can anyone help me out witht this one?
Thanks

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 ADVANCE

Hi 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.

Leela

Regarding error in xml validation 7.1

Hi
I am doing file to idoc scenario. In the sender agreement i selected validation by Adapter and uploaded the particular xsd.after executing the scenario in runtime workbench it is showing sucessfully processed but in the MDT audit log I am getting following error.without validation the file is posting in target system.but when I check the validation by adapter it is giving following error.
Received XI System Error. ErrorCode: CX_XMS_SYSERR_VALIDATION ErrorText: not used at the moment. ErrorStack: System error occurred during XML validation
Transmitting the message to endpoint http://orcdapp1.edfapps.edfenergy.net:51100/sap/xi/engine?type=entry using connection File_http://sap.com/xi/XI/System failed, due to: com.sap.engine.interfaces.messaging.api.exception.MessagingException: CX_XMS_SYSERR_VALIDATION:not used at the moment..
Please give me your inputs.

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

XML Validation with no connection to the internet

Hi,
I'm trying to validate a ml instance document against a xml schema, using the javax.xml.validation.Validator.validate() method. This works fine as long as I have an internet connection, but not when I disconnect from the internet it fails.
I've detected, using a network sniffer, that this is due to the fact that the validation process tries to fetch the XMLSchema.dtd and datatypes.dtd from w3.org. Is there any way to avoid this by prestoring these somewhere? So that the internet connection is not needed?
I need to be able to do validation without a connection to the internet since the environment where my application is deployed does not have such a connection.
Ray

Hi Ray,
Were you able to resolve this issue? I am encountering a very similar problem where I am not connected to the internet and it fails during the newSchema method on javax.xml.validation.SchemaFactory. I have attempted to implement the suggestions of ExtremeGardener and vidyut with no luck.
Per ExtremeGardener's suggestion of replacing xmlns:xs="http://www.w3.org/2001/XMLSchema" with xmlns:xs="XMLSchema.xsd" and storing it locally, it gave me an error for trying to set the "xs" or "xsd" prefixes to anything other than "http://www.w3.org/2001/XMLSchema." I forget the exact error. I also tried to use my own prefix and it did not like that either.
Per vidyut's suggestion of using a catalog resolver, I believe that I have tried that too (if I understand correctly). I created an LSResourceResolver and tied it to the SchemaFactory. I can invoke it for a namespace but that did not resolve the issue because it only invokes the resolver on an import, include, or redefine. I believe that it is trying to reach the internet due to the xmlns:xs="http://www.w3.org/2001/XMLSchema" attribute within the top-level schema element in the XSD and I know of no way to invoke it for that.
I also created an ErrorHandler and tied it to the SchemaFactory. That shows me the errors and they are all related to the standard XML data types defined in XMLSchema.xsd. The errors that I am seeing are all of this form: "UndeclaredPrefix: Cannot resolve 'xs:string' as a QName: the prefix 'xs' is not declared."
I am currently using the SchemaFactory in Java 1.5, but I am thinking about trying the Xerces SchemaFactory since they are not exactly the same implementation.
Does anyone have any other suggestions? Any help you can provide would be greatly appreciated!
Thanks,

HTTP Adaptor - Calling GET operations with parameters

Hi Guys,
I have to call a REST HTTP service on an external system. This is a GET operation (that the HTTP Adaptor has an option for so no initial prob there).
However, a REST GET seems to not accept an xml message as input and in fact needs to be called as a URL string. Further more, the parameter format has to be 'just right'....
The URL that needs calling is as follows, note the parameter format of <id type>.<value>
http://somewebsite/api/rest/acs/customer/uuid.1234
Now, what I don't know is how I can successfully ping this GET service using the HTTP adaptor -- I have been able to define the operation, mark it as a GET etc, but it seems to want a DTD for an input schema and this is not relevant here.... Also, if I didn't have a DTD for input schema, how could I set up the call in a Query transform in any case...?
I'm looking for advice on the HTTP adaptor generally for REST GET and POST calls, and also for the specific problem as above.
Any help would be fantastic!
Thanks,
Flip.

Hi,
Thanks for the response.
Can you elaborate a bit about the GET/SET and the non-support of REST? One of the settings when defining an HTTP Adapter operation is to specify if the operation is a GET or a POST -- doesn't this suggest that it does know how to call a REST GET in some way? Otherwise, what kind of things CAN be called via HTTP Adapter?
Thanks!
Flip.

Administration console on HTTP adaptor

Hi,
I have an existing application which is managed through JMX http connector shipped
with sun's reference implementation.
Now i am evaluating weblogic and want to manage it through the same connector
(and donot want to use the weblogic's admin console). How can i do it?
The documents and googling does not help much.

XML Validation with multiple XSD files (referenced)

Hello,
I know that XML validation with version 7.1 is possible now. However I was provided with a set of XSD files that have references to each other and need to be placed in a hierachical file system order so that references can be resolved.
An element <xsl:include schemaLocation="../../baseSchemas/baseSchema.xsd" /> is used for example. How can I handle that for XSD validation in PI? Can I create the same folder structure or do I need to put all XSD files in one directory and change the import manually?
But most important question: Is it possible it all to use more than one XSD for schema validation?

Dear Florian,
I had encountered such case in a project.
I was given 3 files. One main file and 2 others called Schema1.xsd and Schema2.xsd.
This happens because your data type is not in single namespace, but is being referred across namespaces and software components.
I am assuming that you have read the How to Guide for XML validations on PI 7.1
Best way to do this quickly is as follows.
1. Enable XML validation at adapter engine in the sender agreement.
2. Post a message using HTTP post. (http://sappihttpclient.codeplex.com)
3. Check communication channel in runtime workbench. There will be an error saying which is missing at what path.
4. Create the path mentioned and place the file at that path.
5. Repeat steps 2,3,4 for all the files.
When you are done with this, you will get a proper validation error in case XML file is not correct. And remember to generate XSD from message type and not data type.
Regards,
Vikas
