Help using CollatorEntry for Repository Framework Web Services

Hi All,
Just wondering what are the pre-requisites needed for my KM repository before I can use the collator functionality in web services such as the findResrouces function from the Repository Framework web service?
Should my repository be setup with an index or something? I've been reading the Javadocs and trying a few things out using the WSDL navigator but I have no idea what values I should be putting in for CollatorEntry object. What "name" values should I be putting which correspond to properties?
Could anyone please provide example inputs to put into the WS Navigator say for the method findResources?
When I test out the findResources method
when I input rid: /documents/
CollatorEntries - element1 - name = displayname
ascending = false
I keep getting the error:
Unable to compare: /documents, /documents/.system
hmmm searching SDN doesn't really seem to come up with much information except Collators aren't being used in client applications so they won't be discussed in detail
Any help would be appreciated!

So I have figured out that I need to be putting in the namespace+localname into this collator entry name field but I have been unable to apply an ascending sort based on the accessRid.
I've found using the findResources operation I am getting back resource objects that are not in a file heiarchal order (ie. nodes further down the file directory are being returned before their parentRids.)
Is there a way for me to ensure that findResources returns a sorted array that starts from the top of the document tree and each resource object returned is in the same order as what I see in KM content browser?
Must be a setting or a property that I am missing, when I do a getOrderMechanism operation I notice it is an unordered type. I can't set server order mechanism as its not supported yet....
Does anyone have any suggestions?

Use case for describing a web service

Dear all,
I have a fundamental question for describing a web service.
An analyst will first write (1) a use case for describing the web service and (2) wsdl and xsd files for describing the web service.
As a developer, I would say that artifact (2) is enough. As an analyst, I would still need to document the requirement in the format of use case specification. However, it is not clear for me what should be put in this use case specification and what is the added value of such a use case.
Have you any sample example of this kind of use case in order to describe a web service?
Thanks in advance.

Second, why would you think writing a use case for a Web Service would be any different than any other use case?Sorry for posting twice. I thought the first one failed due to a system error but I was wrong.
From millions of use case I can not find a "good" one.
I have in fact two conceptual questions:
1. I have not much to say about the flow of events. It is simply a request and a response. This is much simpler than a "normal" use case. Am I right?
2. However, I don't know where to put the description of business logic: 2.1 the data sets to be put in the request and response; 2.2 the business logic to construct the response from the request.
I would appreciate any hint or discussion.

Use BizTalk 2006 as a proxy for an external Web Service

Hi
We have a solution that is going to work just as a proxy for an external Web Service.
It works like this:
1. We have a Request-Response receive port that receives the calls for the WS.
2. Different Static Solicit-Response ports that have filters for each method in the WS receive the requests and then send them to the external WS.
3. The response from the external WS is then sendt back to the caller via the Request-Response port in point 1.
This generally works like it should. The only problem i have is when the external WS returns a Fault message. I get this fault from the external WS:
<s:Fault xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"><faultcode>s:Client</faultcode><faultstring xml:lang="nb-NO">Some error message the caller should see.</faultstring><detail><GenericFault
xmlns="http://register.test.com/Common" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"><ErrorCode>SomthingWentWrong</ErrorCode><Message>Some error message the caller should see.</Message></GenericFault></detail></s:Fault>
This message then failes on BizTalk and BizTalk returns this Fault message to the caller:
<SOAP:Envelope xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"><SOAP:Body><SOAP:Fault><faultcode>Microsoft BizTalk Server Negative Acknowledgment
</faultcode><faultstring>An error occurred while processing the message, refer to the details section for more information </faultstring><faultactor>/Hemit.BizTalk.NHN.Position.ws/IPositionService.asmx</faultactor><detail><ns0:NACK
Type="NACK" xmlns:ns0="http://schema.microsoft.com/BizTalk/2003/NACKMessage.xsd"><NAckID>{7AC314FE-2CA3-44AE-8208-180495500481}</NAckID><ErrorCode>0xc0c016b7</ErrorCode><ErrorCategory>0</ErrorCategory><ErrorDescription>There
is an error in XML document (1, 2).</ErrorDescription><ErrorDetail><Fault xmlns='http://schemas.xmlsoap.org/soap/envelope/'> was not expected.</ErrorDetail></ns0:NACK></detail></SOAP:Fault></SOAP:Body></SOAP:Envelope>
So the problem seems to be that the Request-Response port in point one will ONLY accept the real response that is specified in the response schema for that particular method, and not a Fault. And when it receives a fault, it generates its own Fault saying
a Fault message was not expected.
Does anyone know how i can be able to send the actual fault from the external WS all the way back to the caller on the inside?
I know how to do it with an orchestration, but can not figure out how to get it done just with the ports.
Kind regars
John Viggo

Hi John,
Enable Propagate fault message
on the WCF solict –response port.
For the two-way send port, you can choose whether to forward
SOAP fault messages on to the original caller over a solicit-response send port by selecting
Propagate fault message. If this option is not selected, BizTalk Server will generate a NACK. What you see is the NACK.
If it is selected, BizTalk Server will treat the message as a valid WCF response message from the external service and the response message will not be suspended because it is propagated.
Then you need to map the fault message to the actual response in the map. Set this Fault-Message to Caller-Response map in the outbound map of the Requeust-Response port.
In this case of messaging-only scenario, this method shall help in handling the fault message and passing fault details back to the caller. Refer the following articles for more details.
Synchronous web services calls and Faults

SOAPFault

Problem generating stubs for Java EJB web service deployed in OAS

I created an EJB web service and I've successfully deployed it in my Oracle App Server. Some of the methods work fine but others produce the ff error:
org.apache.soap.SOAPException - java.lang.IllegalArgumentException: No Serializer found to serialize [classname] using encoding style [encoding]It seems that the objects specified as parameters in the web service methods exposed are the only ones that had stubs generated for them. Other objects I use, which are usually wrapped inside a Vector, did not have generated stubs.
Example:
public String loginUser(UserDTO userDTO) throws RemoteException, NamingException, SQLException;
public String addItems (Vector vecItems) throws RemoteException, NamingException, SQLException; // where vecItems is a collection of ItemDTO objects In this scenario, stubs were generated for the UserDTO class, but not for the ItemDTO class. In effect, calling the addItems method resulted to the exception I mentioned above.
I did a workaround wherein I declared a dummy method which accepted all the types of objects I needed as parameters so all the necessary stubs can be generated, but this fix doesn't feel like it's the proper solution to my problem.
If anyone can help me, it would be greatly appreciated. Thanks!

Need help in returning error condition from web service

Hi,
I need one help regarding webservice. Currently my web service is returning "true" value when it works fine without any issues but it returns "false" when any any error is encountered. So my question is, can we return error instead of string "false". I dont know how to return exact error from webservice. If you any idea then please mail me.
Below is a small code snippet:
System.out.println("User "+ userFullName + usrKey + " end date has been updated to "+usrEndDate +" in IDM DB");
result = true;
catch (tcAPIException e) {
log.error("Error in finding the user" + e.getMessage());
result = false;
} catch (tcUserNotFoundException e) {
log.error("Error in getting user status" + e.getMessage());
result = false;
} catch (tcStaleDataUpdateException e) {
log.error("Error in updating end date of user" + e.getMessage());
result = false;
}catch (Exception e1) {
e1.printStackTrace();
result =false;
return result;
Here i want to return error instead of false. Can we do that?
Thanks,
Kalpana.

instead of storing false store below
use result=e1.getMessage();

Calculations in Xcelsius using data generated by a Web Service Connection

Hi,
I have set up a web service connection to pull in 4 columns of data: 1. CATEGORY 2. SUBCATEGORY 3. PRODUCT TYPE   4.#OFCALLS. There will be anywhere from 1 to 500 rows of data depending on day of week and time of day. The web service sorts the list by #OFCALLS descending. The OUTPUT VALUES of the web service connection are mapped to cells A19:D518.
Formulas in the spreadsheet take the Top 10 from the list and populate it to cells A4:D13. A formula in cell D15 sums the #OFCALLS for the entire web service connection output (A19:D518).
The data in A4:D15 is mapped to a spreadsheet table on my canvas.   When the report generates, the data from the TOP 10 of the web service connection populates properly, but the cell that should reflect the TOTAL#OFCALLS (D15) shows zero.
Is it not possible to do additional calculations in the spreadsheet based on data generated by the web service connection? A major difference between using an XML Map and a Web Service Connection is the XML Map actually populates the spreadsheet with the new data when it is refreshed. The Web Service connection data never actually appears in the spreadsheet itself, even though it updates to the appropriate vessel on the canvas.   This makes me think that no additional calculations can be done in the spreadsheet based on the web service connection data.
Can anyone tell me if that is correct? If so, then the web service connection would also have to pull in the TOTAL#OFCALLS along with the other data.   This would also seem to greatly limit what you could do with data generated by a web service connection, so I am hoping I am wrong and just don't understand how to do this.
Can anyone clarify this for me? If I failed to give any pertinent info let me know what it is, and I will update my post.
Thanks!

I have seen similar behavior as well. I have live data coming into Xcelsius from a data connection.
A supported Excel formula
=IF(ISBLANK(J2),I2,VALUE(TODAY()-J2))
is then applied to one of the columns to create an additional derived column.
Taking a snapshot of the data shows that the derived column is being populated, however the controls I've tried hooking up to the derived column (charts and labels) are always empty.
Information on whether this is supported would be appreciated.
Thank you,
David

Using Native Oracle XML DB Web Services - REST POST web service possible?

My goal is to expose some pl/sql procedures as a REST web services.
The Database is 11gR2
The request method needs to be a POST (not GET as a request will perform insert/updates ) - the request body will contain a xml structure
Have setup XMLDB Database-native Web Services as per
11g documentation "Using Native Oracle XML DB Web Services"
It seems this setup support only SOAP requests!?
RESTful webservice with GET is (sort of) supported using
Embedded PL/SQL Gateway as describer here:
http://ora-00001.blogspot.com/2009/07/creating-rest-web-service-with-plsql.html
Although no support for POST
Obviously the post is from 2009 so just want to know if anything changed since.
Has anyone found a way to expose pl/sql procedures using XML DB or other approach as a REST POST web services?
(As the relative low number of calls/hour and also the aim to have the least amount of moving parts therefor looking for a DB centric solution)
Thanks
Pete

I think the post referred to was more an exercise of what could be achieved. The quickest way, nowadays, to get this done with not too much hassle is via APEX

Look for JDeveoper 10g Web Services Samples

We would like to use JDeveloper 10g to create Web Services and create JSP pages to use them.
If you know a good starting point or where I can find examples, please let me know. I have found some for 9i, but I hope 10g will make the job easier.
Thanks a lot.

My original message was referring to Mike's following response.
The problem is, in the oc4j10.0.3 generated stub, there is no
m_httpConnection = new OracleSOAPHTTPConnection();
so how do you set up the proxy properties to the connection?
Quote
It may be that you require a proxy server, optionally with proxy authentication to access the Internet from within your intranet. If you are using a proxy server as I am guessing here, look inside your stub for the line that reads:
m_httpConnection = new OracleSOAPHTTPConnection();
then after it add these lines:
Properties props = new Properties();
props.put(OracleSOAPHTTPConnection.PROXY_AUTH_TYPE, "basic");
props.put(OracleSOAPHTTPConnection.PROXY_USERNAME, "proxy_username");
props.put(OracleSOAPHTTPConnection.PROXY_PASSWORD, "proxy_password");
props.put(OracleSOAPHTTPConnection.PROXY_HOST, "proxy-host");
props.put(OracleSOAPHTTPConnection.PROXY_PORT, "80");
m_httpConnection.setProperties(props);
where "proxy_host" is your proxy serve, "80" is your proxy server port and if your proxy requires a username/password, update the lines above where username and password are defined; otherwise delete those lines.
Mike.

Can use PLSQL to develop PLSQL web services?

Hi,
I know we can use JDeveloper to create PLSQL web services.
How about if we want to develop plsql web services using PLSQL itself, is that possible?
Please advise.
Thank you.

I found the article on how to call web services from within database.
http://www.oracle.com/technology/tech/webservices/htdocs/samples/dbwebservice/DBWebServices_PLSQL.html?_template=/ocom/technology/content/print
The example is for oracle9iR2.
It's looks like it's quite a bit of work compare to use java to call web services. I wonder with Oracle10g database, is there any improvement that will simply the steps? Would appreciate some advice as i don't have oracle10g environment in my place.
Thank you.
