File Adapter - Native XSD - DTD to XSD

Hello,
a. I have to read a data file using file adapters, which is sent in the following pattern (dtd below):
<?xml version="1.0" encoding="US_ASCII"?>
<!DOCTYPE message SYSTEM "d3l.dtd">
<message name="ITEM" type="ItemArray" object="ITEM_BO">
<struct id="ItemRecord">
     <field name="Process_Flag"><limstring delimiter=";"/></field>
     <field name="Item_Number"><limstring delimiter="|"/></field>
     <field name="Attribute2"><limstring delimiter="|"/></field>
</struct>
<limarray id="itarray" contchar="*" endchar="!">
     <typeref type="ItemRecord"/>
</limarray>
<struct id="ItemArray">
     <field name="ItemLine"><typeref type="itarray"/></field>
</struct>
</message>
b. whose sample data is as below:
;P;|00030||TEST1|*;P;|00040||TEST2|!
c. I am now in the process of designing my native xsd:
i. I can either use convert dtd to xsd (or)
ii. create my own sample schema definition which is similar to the above data structure
In step (i), I could not convert the dtd to xsd, due to reference to d3l.dtd file.
If anyone can advise where this d3l.dtd file can be found and where I should place it in 'SOA' it would be really helpful.
In step (ii), I find that through the wizard I am able to create simple csv file styles, but not able to create the above data structure due to different delimiters (; and |) and also due to delimiter-embedding of data.
It would be really helpful if someone can advise on how I must proceed with this issue.
Thanks,
Santhosh

Hello Ramana,
As for step one, the 'd3l.dtd' is a file which all Oracle Interconnect DTDs look up to. I am not able to locate it.
As for step two, the data file the structure is of the following pattern :
i. entire data is in single line of the data file..
ii. first element will be embedded with semi colon
iii. the other elements inside pipes
iv. end of record is indicated using *
v. end of file is indicated using !
These are the rules based on which the data file is built.
I don't have much experience in creating xsd (except for simple native xsds that I have created using the native xsd wizard of Jdev-BPEL).
Using the native XSD wizard that is available with JDev-BPEL, I trust I cannot create complex data structure which is of the above pattern.
If there is a good tool/method through which I can create the xsd as per the above listed rule structure, please advise.
Thanks,
Santhosh

File Adapter - Native Format Builder

Dear All,
In File Adapter - Native Format Builder exists option "Number of rows to skip". But this means how many rows from beginning of file to skip,
can somebody help to define how to skip n rows from the end of file.
Thanks in advance!

There is no option available to skip rows from end. But if you know how many rows are there in the file and how many you want to skip, then you can use the option of "Number of data rows to process" and process only number of rows you want to actually process.

File Adapte picking up XML if XSD valid without verifing the XSD in adapter

hi',
I am facing one issue
I have a sample XML file which I want to read through BPEL process
for this I have configured the file adapter with the schema and reading the file adapter with the receive activity
next I have created one XSD file (which file adapter referes to) and one XML file,
File adapter reads it after the XML file gets validated with the XSD which is kept in a location *'/test/xsd/emp.xsd'*,
now the issue is that the file adapter is picking up and initiating the process without verifying the XSD mentioned in the adapter
it is only checking the XML file with the XSD mentioned in the XML,
for example if I have a xml file which is refering to some other schema it also gets read by file adapter without worring about what schema is mentioned in file adapter
please advice me is this the way File adapter works in Oracle BPEL or I am doing some thing wrong
I am using SOA suite 10.1.3.3.0 which is deployed in UNIX enviornment.
thanks
Yatan

thanks Ketan ,
as you suggested, after adding validateXML to true, the XML is getting validated to the XSD in the adapter,
the process is getting invoked and the receive activity is throwing error of 'Invalid XML', this is perfect as I expected
however now the issue is, the file which is invalid in terms of XSD present in the file adapter is still being archived to 'success dir' i.e. 'LogicalArchiveDirectory', ideally it should have moved to fail directory,
but if the XML file is not complete or having some error in terms of the XSD it is refering to 'target namespace' and 'target location'
then it will move to the fail directory and the receive activity is also showing the error,
see this is how I have configured my bpel.xml file for the file adapter.
<activationAgents>
<activationAgent className="oracle.tip.adapter.fw.agent.jca.JCAActivationAgent" partnerLink="Read_Tph_ProdTrans_File">
<property name=*"prod_trans_success_file" type="LogicalArchiveDirectory"*>/aaa/bb/ccc/wis/tph/bpl_inbound/adjust/success</property>
<property name=*"prod_trans_incoming_file" type="LogicalDirectory"*>/aaa/bb/ccc/wis/tph/bpl_inbound/adjust/new</property>
<property name="portType">Read_ptt</property>
<property name="rejectedMessageHandlers">file:///aaa/bb/ccc/wis/tph/bpl_inbound/adjust/fail</property>
</activationAgent>
please advice how to bring this adapter to proper behaviour.
thanks
Yatan

File Adapter - Native format Builder button not Appearing

Hi,
When We go through the file adapter wizard and on the screen where we define the schema, there is a button 'Native format builder'. But on Jdeveloper Version - 11.1.1.3.0, it is not appearing. Has this been removed in this release?
regards,
Rajesh

at step 8 of 9 of the file adapter wizard, the icon appears as a cog, on the right, with caption "define schema for native format".
I have JDev 11..1.1.3.0
The problem might be with the version of the SOA extensions you have installed....

One file Adapter NXSD file dynamic

Hi all,
I will get different inputs based on the input request ID i have to do write the file using file adapter .
so the question is if i have 10 files is it necessary to create 10 File adapters or can i achieve this using a single File adapter and multiple NXD or XSD files in a folder .
select the xsd or NXSD at runtime based on the input request ID.
The best thing with this approach is even for a new transformation request i will just add the xsd or NXSD in the folder and update the DB no need to create a file adapter from scratch.
Thanks
Phani

Hi,
You cannot change the XSD for a file adapter at runtime....u can choose to write an opaque file with an native format is not required option checked.

File Adapter Delimited File

Hi All,
I am writing a delimited file using the file adapter, i have built the XSD using the native format builder. Inside the BPEL, i get the data using a query, this query returns the data with delimited information between fields, but the output XSD came in such a way that there is only one element which holds the entire record. At runtime i get the information from database lookup and assign that records to invoke input variable of file adapter.
XSD of target file adapter...
<?xml version="1.0" encoding="UTF-8" ?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:nxsd="http://xmlns.oracle.com/pcbpel/nxsd"
xmlns:tns="http://TargetNamespace.com/ReadFile"
targetNamespace="http://TargetNamespace.com/ReadFile"
elementFormDefault="qualified"
attributeFormDefault="unqualified"
nxsd:version="NXSD"
nxsd:stream="chars"
nxsd:encoding="UTF-8"
>
<xsd:element name="Root-Element">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="Child-Element" minOccurs="1" maxOccurs="unbounded" nxsd:style="array" nxsd:cellSeparatedBy="${eol}">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="C1" type="xsd:string" nxsd:style="fixedLength" nxsd:length="100" />
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:schema>
So, the thing is file is getting written to, but the records are getting right aligned, as you can see the length is 100, so the file i am writing is coming like
records starting with the spaces, but the data which i am getting doesn't return any spaces at the starting of the record, it has spaces in the middle and the end of the record. I want the records to be left aligned. Is there any property which i can set for the element in the XSD for the data that gets assigned to make it left aligned.
Please help Experts.
Thanks,
Naresh

You can see the option of adding padStyle as head.. More detail check the below link and search on padding option which helps u in alignment.

Can I use a schema with no targetnamespace with the file adapter?

I am loading a file using a file adapter configured to use an xsd from a third party, the third party controls the xsd and incoming xml and does not have a targetnamespace defined in the xsd or xml.
When I define a file adapter for it the wizard indicates that I need to fix the xsd by adding a namespace. I dont have control over the xsd or xml as they are an external party.
I think I can hand edit the wsdl and change the import statement that requires a namespace to an include statement with no namespace.
Have you run into this before? Will that work?
Thanks,
John

Hi John,
Did we get any solution for this ?
Even in our case, the third party controls the xsd & incoming xml message. Both does not have a targetnamespace defined. The file adapter wizard indicates that we need to fix the xsd by adding a namespace. As a workaround, we manually added the target namespace to xsd and created file adapater. Now the question is how do we automatically add the name space in xml message as well, so that it can be parsed by BPEL process
thanks

How to automate File Adapter Configuration

I am configuring a File Adapter manually then it generates WSDL file and jca files which contains File Adapter configuration. I have XSd file through the XSD can I generate these files (WSDL & jca)?

I have XSd file through the XSD can I generate these files (WSDL & jca)?No. Only adapter wizard should generate these files. Can you let us know more about your use case and tools you are working with?

File Adapter : read XML file with data validation and file rejection ?

Hello,
In order to read a XML file with the file adapter, I have defined a XSD that I have imported to my project.
Now the File Adapter reads the file correctly but it does not give an error when:
- the data types are not valid. Ex: dateTime is expected in a node and a string is provided
- the XML file has invalid attributes.
How can I manage error handling for XML files ?
Should I write my own Java XPath function to validate the file after is processed ? (here is an example for doing this : http://www.experts-exchange.com/Web/Web_Languages/XML/Q_21058568.html)
Thanks.

one option is to specify validateXML on the partnerlink (that describes the file adapter endpoint) such as shown here
<partnerLinkBinding name="StarLoanService">
<property name="wsdlLocation"> http://<hostname>:9700/orabpel/default/StarLoan/StarLoan?wsdl</property>
<property name="validateXML">true</property>
</partnerLinkBinding>

ESB File Adapter data validation issue

I have a really simple ESB process.
File Adapter Read
(XML format with XSD) --> Routing Service --> SOAP Call to BPEL Process
Quite simply, the ESB uses the File Adapter to read an XML file which has an associated XSD. The contents are then routed to a BPEL Process.
If the XML file is valid in syntax but contains an element which is not in the XSD, the file contents are pushed to the BPEL process which has validateXML set to true - thus the error is caught and handled by the BPEL process.
This is what I want to happen.
If the XML file is invalid in syntax - for example -
<TAG>hello</WRONGTAG>
The ESB process rejects the file and stops dead.
I would rather the invalid file is pushed to the BPEL so that the BPEL can handle the error.
Why?
Because my error handling in the BPEL picks up the invalid XML format and emails the users to inform them there is a problem.
Can someone help? Is this possible? Thanks.

Hello again! You are now aware of the problem as there has been a lot of conversation between myself and Dave Berry [and you!] regarding this issue.
For the rest of the readers - here is a brief summary of progress so far. Sorry but there has been so much communication that I think the best way is to direct you to various links.
If an adapter fails in ESB, then it is possible to trap these failures and handle them as documented here:
Dave Berry said:
you need to look into the adapter rejection handlers which are documented on OTN ESB page in the exception handling lesson and the adapters OTN dev resources page http://www.oracle.com/technology/products/integration/adapters/dev_support.html
I had also devised my own solution in the meantime, which involves reading the input file as opaque schema and passing this to a BPEL process which converts it to an XML document! This can then be validated and use standard BPEL error handling to find any problems in the file format etc.
See my blog for a tutorial on doing this:
http://soastuff.wordpress.com/2007/06/06/handling-opaque-datatypes-in-bpelesb/
The only problem with this at the moment is that the BPEL function ora:parseEscapedXML has a bug in it - so it fails if the XML does not comply with the XSD it tries to convert to.
This in turn causes an ORABPEL-09500 error which does not seem to get handled by the BPEL process so the process fails.
As things stand, this bug remains - though Dave Berry has been very helpful in identifying it and bringing it to Muruga's attention. Hopefully we can get a fix (?) and a workaround whilst the fix is being implemented (?)
Cheers.

File Adapter Wizard Step 4

I'd like to write out a message variable to a file. When I use the file adapter, the wizard asks for a schema in step 4. There is no xsd schema defined for the message.
I tried using the "Schema is Opaque" checkbox to create the partnerlink but then I get a type mismatch between the message I want to write out and the opaque "Write_msg" of the adapter.
What should I do to write out a message using the file adapter when there is no xsd? How do I get past step 4 in the wizard? Is there an example somewhere?
Thanks,
Bret

Google's wsdl is available for download to the local file system. It's not available dynamically via an API, at least not that I've been able to find. Perhaps because they require you to sign a license agreement checkbox and access via an API would not satisfy their legal department? I guess we need a new WS* specification: WS-Legal or WS-Licensing.
I did create my partner link just as you described. My local file is called GoogleSearch.wsdl and the partner link wizard creates a file called GoogleSearchRef.wsdl. But there is no xsd created.
Maybe the only workaround is to chop the message definition out of the wsdl file and manually create an xsd. But that would be a severe support workload, since Google's wsdl may change from time to time and a new xsd would then have to be generated. Perhaps the process of generating an xsd from a wsdl could be automated. What do you think?

XSd-validation isn't performed when invoking file Adapter

I've configured an ESB where data needs to be transformed using a file adapter and a db adapter.
The deleimted files first need to be validated using xsd (native transformation) and if validation was performed correctly they can be transformed and loaded into db tables.
The xsd-validation isn't performed in my use case where some fields are required, have a decimal-format etc., if the files don't comply they're still picked up and being transformed to the db adapter, where the insertion will fail then because the file had errored records in it.
I'm using esb 10.1.3.3 in this case.
kind regards,
Nathalie

Hi Nathalie,
I'm not able to define properties on my esb routing
service in release 10.1.3.3, the definition tab isn't
showing any detailed information for my routing
service.Strange, we're also using 10.1.3.3. Make sure in the ESB Control when you select the routing service, that the operation for which you want to validate the payload is selected. If it is selected, the operation details section should show the validation option. Also see page 3-14 of the ESB Developers Guide. You can also change the esbsv-file:
<operations>
<operationInfo guid="xyz" qname="Test.Insert.insert" wsdlOperation="insert" mepDisplayName="One Way" mep="OneWay">
<request validate="true" xmlns:tns="http://xmlns.oracle.com/pcbpel/adapter/d
b/top/Insert" element="tns:TestCollection"/>
</operationInfo>
</operations>
</service>
using the validate="true" option.
No logging is being generated for this matter, so I'm
not sure which problem I'm facing wright now. I will
bounce the service and try again.We had such an issue when we didn't validate payload at runtime and inserted data using DB adapter. Our TopLink mappings didn't correspond to the XML data to be inserted. That caused only 2 tables out of 4 to be updated, without any error logged. Enabling validation, resulted in an error being thrown; the behaviour we wanted.
The only thing that's of importance here, is that I
need to define this functionality within BPEL and not
ESB, the customer has only acquired bpel for this
matter because human task integration was necessary.One of the advantages of 11g fortuntely is that separation of concerns will be better. It will be much clearer where to use adapters. Not that this helps in your current case right now :-s
I should be able to accomplish the xsd validation
inside a bpel configuration.That should work, good luck!

File Adapter: trailing space in field using XSD:Decimal in a CSV file

Hi Folks,
I have a problem which i am unable to understand fully.
We have a SAP to file via XI scenario where a mail adapter is used. We are producing a CSV file as an mail attachment.
The issue is all the decimal fields have an extra space before the next delimiter i.e. comma.
The data type used in mapping is XSD:Decimal with 'fraction' set as 2.
I have checked the source XML and there is no trailing spaces there. Initially i thought this might be due to doing the conversion using transformation beans in mail adapter, to rule this out i checked other files produced using FILE adapter they also appear to have same issue.
I can't get my head around it, could not find any parameter i need to pass in content conversion either in MAIL adapter or FILE adapter to supress trailing space before the delimiter.
I suppose this must have occured with others as well.
Any directions would be greatly appreciated.
Btw, we are on PI 7.0 and ECC 6

Hi Mouchel,
I personally didnot encounter this kind of issue with the file adapter at any point of time. I would suggest you to check the message mapping before and after payload in sxmb_moni. If you see in mapping you may not find out, so view the source in notepad and then see.

Converting XML file to DTD or XSD file

Hi everyone,
We're currently doing an IDOC to File. The file should be in XML format. Right now, we have a sample XML file. We need to convert the file to DTD or XSD and then upload this in XI to be able to get it structure. We've tried different conversion tools to do this, however, the converted DTD/XSD file still has errors when we load it to XI. What we're thinking is to create a data type to achieve this. These are some of the fields in the file.
<messageHeader creationDate>
<catellae:gTTSDataDelivery creationDate="X" (...)>
*/<catellae:()>/<txnId>
*/<catellae:()>/<items>/<item>/<quantity>
*/<catellae:()>/<items>/<item>/<unitOfMea>
*/<catellae:()>/<items>/<item>/<prodDesc>/<matType>
*/<catellae:()>/<shipToAddress>/<nameAndAddress>/<city>
*/<catellae:()>/<shipToAddress>/<contactInformation>/<communicationChannel ()
It seems that there are more than 3 nodes. And in XI, only three nodes are allowed. Could you tell us how should we create the data type for this? Thanks in advance!

External dependency on remote dtd and xsd files

The question bugs me for years, please help.
Should we download external dtd and xsd files declared for web.xml and faces-config.xml and pack them in the war files to eliminate the external dependency.
e.g.
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd
http://java.sun.com/dtd/web-facesconfig_1_0.dtd
Thanks

SAP HELP
<i>You want to import an XSD document myMessage to the Integration Repository; this document references three other XSD documents myStr1, myStr2, and myStr3 by using the <include> statement.

Next, create further external definitions for myStr1, myStr2, and myStr3 in the same namespace and specify the source for each of these documents. If the source is not contained in the document itself, you will find it in the referencing document. If you refresh the display of the external definition for myMessage, the External References tab page shows that the documents have been found in the Integration Repository. You can then navigate to the other referenced external definitions in the Integration Repository by double clicking.</i>
