Coarse-grained Web Service

Hi all,
I noticed, that services in the ES Workplace has small and clear interface. But if i want to develop a complex UI, let's say object hierarchy contains many levels. How will it be implemented as Web Service? One big Web Service?
If i have fine-grained Web Service, than i must always save data on DB, as Web Service may requere ID. But it is not the way for UI.
This restriction is based on the fact, the Web Services must be stateless.

Paul

well,
probably things are just a matter of taste.
I am from time to time building dynamic UIs in a completely SAP agnostic environment by combining calls to several SAP (custom made ones) and non SAP services.
Personally I did not like BAPIs at all. To call a commit explicitly seemed very anachronistic to me.
Also I did never ever feel a need to testrun an operation. To my knowledge no enduser wants to <b>test</b> if e.g. a purchase order could be created or not. To me the usual way is to have actual data (availability, pricing, etc...) checked already (which is not determined by a testrun but via Get services) and then try to create that order...with two outcomes, either the order being created sucesfully and a receipt returned or or the order not being created sucesfully and a meaningful error condition returned hinting me on how to overcome that condition.
To me the possibility to automatically create service consumers (clients) in almost every language (programming environment), get the data type mappings and the transport layer stuff done automatically and having an interface and service description (WSDL) which is (at least in theory) understandable by the SAP agnostic puts web services so far ahead of BAPIs, that IMHO they are not comparable at all.

BPEL build error when invoke an extrenal Web Service that returns an Array

Hello,
I built with JDeveloper a web service that returns an Array of Java Bean classes and I try to invoke this web service from a BPEL process. The wsdl file is automatically generated by the JDev. When I built the BPEl project I obtained the following error:
[bpelc] [Error] :-1:-1: src-resolve.4.2: Error resolving component 'SOAP-ENC:Array'. It was detected that 'SOAP-ENC:Array' is in namespace 'http://schemas.xmlsoap.org/soap/encoding/', but components from this namespace are not referenceable from schema document 'http://malangiu-ro:8988/cde-Project-context-root/CdeFactoryWS?WSDL'. If this is the incorrect namespace, perhaps the prefix of 'SOAP-ENC:Array' needs to be changed. If this is the correct namespace, then an appropriate 'import' tag should be added to 'http://malangiu-ro:8988/cde-Project-context-root/CdeFactoryWS?WSDL'.

Hi,
BPEL and BPEL PM do not have a good support for SOAPENC-Array: it would be very difficult to create such an array in BPEL or to receive it and manipulate it.
The (unfortunately very intrusive) work around is to change the WSDL of the service to use a XML type defined using XML schema. This is all the more painful that JDev 9.0.4 does not have strong support for complex types.
In general though, I would highly recommend this best practice:
1) Start by define the WSDL contract first
2) Then generate the server side skeleton to implement it
3) Use BPEL as the client to this contract.
By starting with the contract first, you make sure that 1) your interfaces are clean and coarse grained.
2) things like java objects, sessions, etc to not leak through the interface (which would be the worst thing that could happen because it would closely link the client and the server.
Sorry for not being more helpful. This will get radically cleaner in Oracle AS 10.1.3.

Expose Object Oriented Service code as Web Services?

Hello All,
I would appreciate for your insight on this matter!
Web Services are basically RPC (Procedure Oriented) over Soap. Each service invocation by a client results a procedure execution on the server side (In many case, a service class may need to be instantiated before the procedure can be called).
Suppose I have developed server-side logics in Object Oriented manners. How can I expose the OO server logics as Web Services? Does JDeveloper handle OO services any different from PO (procedure-oriented) services as far as the generated wrapper code/interface and WSDL?
Specifically, I have the following example in mind. Assume we are able to successfully expose an OO services. A client calls one of the OO service (let's say service1 in portType1) the 1st time, and establish some transit state (not committing into DB), the same client subsequently calls another service (service2) of the same server portType1. How would the server retrieve the transit state established earlier by service1 while executing service2? (note, this situation would not be resulted in a procedure-oriented case. since each RPC call is independent from the others)
I realize that "stateful" deployment may be of an option. However, stateful seems relying on client cooperation (e.g., via cookies) to establish context across multiple invocations. This may or may not be possible given an arbitrary client parties write its client code based on a WSDL.
Another option I can think about is for Jdeveloper to generated different code for PO services vs. OO services. However, it seems not the case in current Jdeveloper.
Thank you so much!

Web services in general have two styles of invocation: RPC style and Doc style. RPC maps as you say directly to methods on Java class (or if a DB PL/SQL package to procedures and functions).
The alternative, DOC, generally (though not all the time) maps to a message oriented interface. Often DOC style Web services map to messaging infrastructure such as Java Message Service Queues and Topics.
That said RPC works well with EJB's, the component model for J2EE.
Often what folks will do is build a service layer that is very coarse grained when exposing backend infrastructure as Web services. This abstraction typically hides a more OO underpinning (or quite often hides a very procedural backend too).
The bottom line is the Web services do not force an OO paradigm but nor do they hinder you in any way from adopting an OO paradigm.
In terms of JDeveloper currently it supports RPC and supports DOC only with some tweaking. On the server side, the Oracle9iAS infrastructure supports both DOC and RPC.
Hope this is a start to answering what I think is a hard question to answer!

Problem with web service that returns an object with a String that have som

Hi everybody:
I have a problem with a web service I am doing, I have made a web service that returns a collection of objects, the objects have a set of properties, there is one property that is a String,this property consists in a text fragment that could have some characters that are considered special in XML like &, <, >, " and that's why when I execute the service from a client an exception is thrown:

OAAM web services implementation class for WebSphere 6.1

Hi All,
My client is running OAAM 10.1.4.5 and looking to migrate to WebSphere 6.1. I'd like to replace the (default) Apache Axis web services implementation class with a custom-built WebSphere 6.1 implementation class. Does anyone have any code they'd been willing to share?
Regards,

It is may be because BO is not ready for Java 2 and you can find more info about readyness of applications at
http://publib.boulder.ibm.com/infocenter/wasinfo/v6r0/index.jsp?topic=/com.ibm.websphere.nd.doc/info/ae/ae/csec_rsecmgr2.html
I am not sure if BO is prepared for the very fine-grain access control programming model that Java 2 security is capable of enforcing.
May be some one from PG should be able to answer readyness of BO with Java2.

Error while invoking a WS-Security secured web service from Oracle BPEL..

Hi ,
We are facing some error while invoking a WS-Security secured web service from our BPEL Process on the windows platform(SOA 10.1.3.3.0).
For the BPEL process we are following the same steps as given in an AMIS blog : - [http://technology.amis.nl/blog/1607/how-to-call-a-ws-security-secured-web-service-from-oracle-bpel]
but sttill,after deploying it and passing values in it,we are getting the following error on the console :-
“Header [http://schemas.xmlsoap.org/ws/2004/08/addressing:Action] for ultimate recipient is required but not present in the message”
Any pointers in this regard will be highly appreciated.
Thanks,

Hi James,
Thanks for the quick reply.
We've tried to call that web service from an HTML designed in Visual Studios with the same username and password and its working fine.
But on the BPEL console, we are getting the error as mentioned.
Also if you can tell me how to set the user name and password in the header of the parter link.I could not find how to do it.
Thanks,

Hi,
I have no problem with item :P15_EV_LCL this is having a value my probem here is i am using java script to display the value in different color based on the condtion case
eg:
select
case
TRUNC((
( (NVL(Z."AEWP",0) - NVL(Z."BEWP_Final",0) ) / DECODE(Z."BEWP_Final",0,NULL,Z."BEWP_Final") ) * 100
),2)
= :P15_EV_LCL
then
span style="background-color:lightgreen"
|| TRUNC((
( (NVL(Z."AEWP",0) - NVL(Z."BEWP_Final",0) ) / DECODE(Z."BEWP_Final",0,NULL,Z."BEWP_Final") ) * 100

end "Effort"
from actuals Z
If i dont use this <Span style="Background-color:color"> i am able to generate data in excel sheet if i use this color coding i am not able to get data in spread sheet.
Please suggest

Unable to capture return values in web services api

At the time of login to web services if my server is down ,
it returns following error :
java.lang.StringIndexOutOfBoundsException: String index out of range: -1
        at java.lang.String.substring(String.java:1438)
        at java.lang.String.substring(String.java:1411)
I want to capture this error so that i can try another server to login. how do i capture this error
Another place where i want to capture the return Value is when i look for a report on the server
rh = boBIPlatform.get("path://InfoObjects/Root Folder/"src_folder"/" + reportName +
                           "@SI_SCHEDULEINFO,SI_PROCESSINFO" ,oGetOptions);
oInfoObjects = rh.getInfoObjects();
CrystalReport = (CrystalReport)oInfoObjects.getInfoObject(0);
Here if the report is not there on the server , it returns a null handler exception.
but if i try catching it by checking my responsehandler is null like rh == null it does not catch it.
Any help will be appreciated
thanks

Ted : i have two cases
1)   server = server_st.nextToken();
    providerURL = "http://"server"/dswsbobje/services";
    sessConnURL = new URL(providerURL + "/session");
   Connection boConnection = new Connection(sessConnURL);
   Session boSession = new Session(boConnection);
EnterpriseCredential boEnterpriseCredential = new    EnterpriseCredential();
              boEnterpriseCredential.setLogin(userid);
boEnterpriseCredential.setPassword(pwd);
boEnterpriseCredential.setAuthType(auth);
SessionInfo boSI = boSession.login(boEnterpriseCredential);
I have got a list of servers running web servcies stored in my tokens. when i pass the first server name say " test:8080" and that server is down , i want to catch somewhere in the code above that it did not get the connection so that i can loop back and try with the second server say test1:8080
This is for failover purposes.
at present when i was trying to capture return value of boSI it breaks giving the error
java.lang.StringIndexOutOfBoundsException: String index out of range: -1
at java.lang.String.substring(String.java:1438)
at java.lang.String.substring(String.java:1411)
2nd case :
I am geeting reports from the server and scheduling them:
i run the following code which works fine if reports is there
rh = boBIPlatform.get("path://InfoObjects/Root Folder/"src_folder"/" + reportName +
"@SI_SCHEDULEINFO,SI_PROCESSINFO" ,oGetOptions);
oInfoObjects = rh.getInfoObjects();
CrystalReport = (CrystalReport)oInfoObjects.getInfoObject(0);
Here if the report is not there on the server then i should be able to catch from the response handle rh that it has got a null value.
but rh does not return a null value
the code ultimately throws a null handle at the following line
CrystalReport = (CrystalReport)oInfoObjects.getInfoObject(0);
i am not able to catch the null value there also.
hope you got my issue.

How to allow access to web service running under ApplicationPoolIdentity

Hi All,
I have a WCF web service hosted in IIS 7 (or maybe 7.5, whichever comes with Windows server 2008 R2) using DefaultAppPool running under ApplicationPoolIdentity per Microsoft's recommendation. The web service needs to call a stored procedure to insert data
to a db. The web server is on a different VM than the database server. The db server is running SQL 2008 R2. Both VMs run Windows server 2008 R2.
When the web service tries to connect to db, it encounters this exception:
Exception in InsertToDb()System.Data.SqlClient.SqlException (0x80131904): Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'.
at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection)
Here's the connection string in web.config:
Application Name=somewebservice;Server=somewebserver;Integrated Security=SSPI;Database=somedatabase;Connection Timeout=60"
How should I configure SQL security to make this work?
Thanks in advanced.

Thanks for the link Dan. Maybe I'm the one who cause the confusion :)
If I understand you(and Erland) correctly, you suggest using a custom, domain account for application pool identity. However, if we do that, our IT will need to maintain those accounts, and they don't want that. So I'm choosing a built-in account called
ApplicationPoolIdentity as the application pool identity, but it's not working. Network Service, on the other hand, works, but my boss wants us to follow MS's best practice.
What's puzzling is that according to this: http://learn.iis.net/page.aspx/624/application-pool-identities/, both Network Service and ApplicationPoolIdentity uses machine account to access network resource (like db in this case), but in my case, Network Service
works, but not ApplicationPoolIdentity.
Hallo Stephen,
with respect - it seems to me that only idiots are working at your IT ;)... It is absolutely useful to work with "service accounts" created within the domain. That's the only way to manage and control accounts!
If you want to "pass through" the identity of the web user (SSO) you have to check whether the app pool is set to "allow impersonate". As far as I understand the ApplicationPoolIdentity-function the app pool will create a unique user named as the service.
I assume that will not work with the connection to the sql server because this user is unknown.
Local Service will not work because it's restriction is located to the local machine.
Network Service will work because access to network resources will be available.
So my recommendation is to use a dedicated service account or impersonation:

Web Service deployed with admin_client is not working

Hi,
I'm usung SOA Suite 10.1.3.1 and Eclipse WTP 3.2.2.
The thing is that I developed a Web Service with Eclipse using the plugin for generating web services. Then I exported my project to a .war file from eclipse as well.
For deploy my web service in oc4j, I tried from the oc4j console in Applications --> Deploy and Next-Next wizard and using the .war file generated by Eclipse. I got the application deployed and I can check that the wsdl is working in http://localhost:8888/Hello_Web2/services/Hello?wsdl
But the main problem is when I try to deploy using the admin_client command tool running the command: java -jar admin_client.jar deployer:oc4j:opmn://localhost/home oc4jadmin welcome1 -deploy -file d:\TEMP\Hello_Web.war -deploymentName Web5 -contextRoot "/". Everything seems right, I can see the application created in the console, but when I try to access to the web service using "http://localhost:8888/Hello_Web2/services/Hello?wsdl" I get and Http 404.
What is wrong with the command method?
Many thanks in Advance,
Alberto

Hi,
As the custom web part works well in other browsers, the issue may be related to the IE itself.
Have you tried the methods below?
Use compatibility mode to check whether it works.
Open IE->Tools->Compatibility View Settings
Add the site into Trusted sites to check whether it works.
Open the IE->Internet Options->Security->Trusted Sites->add the site into the zone
What’s more, you can also switch the Document mode to IE 10 or lower to check whether it works.
Thanks & Regards,

Questions on using a SOAP web service's data in a Crystal Reports report

I'm attempting to create a report using CR 2008, accessing data from a SOAP web service. I've run into a few problems, and need some advice.
1) CR doesn't seem to support WSDL files that use relative URI imports (for example, I have a relatively complicated WSDL file that imports other WSDL files and schemas using relative URI locations). To solve this problem, I have downloaded all of the files to my local hard drive, and changed the "location" attributes to point to local files. Is there any other solution to this problem?
2) CR doesn't seem to support circular references within schema files. To solve this problem, I have removed circular references from my local schema files. Of course, my actual web service will still potentially return data structures with these circular dependencies. Is there any other solution to this problem?
3) CR doesn't seem to support request documents that allow for arrays of elements. For example, my schema allows the user to specify an array of Instruments that should be returned by the web service. In the meantime, I have changed the schema to only specify single instances of the Instrument element in the request. Is there any other solution to this problem?
4) CR doesn't seem to support empty values for optional attributes that are specified in the schema. So, when the "Enter Values" parameter form appears, I am required to enter values for these attributes, even though they are listed as optional in the schema. To avoid this problem, I have commented out the optional attribute values in the schema. Is there any other solution to this problem?
5) When the schema specifies that a value is based on a restricted simple (string) type, the CR parameter form shows a drop list with ellipses (...), but the drop list does not contain the enumerated types specified in my schema. Instead, I must manually enter a value. Do you know of any reason why the drop list is not populated?
6) The SOAP response document from my web service is relatively complicated. So, in the "Data" page of the Standard Report Creation Wizard, each and every XML element level of the response document listed in the schema is shown as a separate entry. If I choose just the top level element ("fetchInstrumentSetResponse"), then very little data is shown on the next page of the wizard (only the ID attribute). But, if I select each and every element type from the response document, CR prompts me for the request document parameters for each row I have selected (I see the same form 30+ times), even though there really should only be a single SOAP request to the web service to return this response document. It seems to be treating each of these elements as a separate "database table", with a different query string for each. Am I using this feature incorrectly?
If you can point me to somewhere in the documentation that handles this in more detail, that would be great (all I could find were the step-by-step instructions on how to connect to a web service as a data source).
Thanks!

Error while scheduling through web service

We have created Web service through WSDL of OBI Publisher. Also we created a web service proxy client to call the services offered by OBI Publisher. We actually want to "Automate the Scheduling of Reports" according to our requirement:
1. We used to schedule the reports manually by giving the parameters(used to populate data in reports) and other fields like select report name, report destination, format of reports ( .pdf, .docx,etc) through Oracle BI Publisher.
2. As there are thousands of permutations of report input parameters possible, so it is difficult to schedule them manually.
3.We also want to schedule report to a particular folder according to some parameter, for the ease of the user visibility.
Above requirements are not currently available with Oracle BI Publisher.
We are getting error while scheduling through ScheduleRequest class.
The client.java is as follows:
public class ScheduleServiceClient
@WebServiceRef
private static ScheduleService_Service scheduleService_Service;
public static void main(String [] args)
    scheduleService_Service = new ScheduleService_Service();
    ScheduleService scheduleService = scheduleService_Service.getScheduleService();
    // Add your code to call the desired methods.
    try {
                FTPDeliveryOption ftpdo =new FTPDeliveryOption();

Error while deploying a web service whose return type is java.util.Date

Hi
I have written a simple web service which takes in a date input (java.util.Date) and returns the same date back to the client.
public interface Ping extends Remote
* A simple method that pings the server to test the webservice.
* It sends a datetime to the server which returns the datetime.
* @param pingDateRequest A datetime sent to the server
* @returns The original datetime
public Date ping(Date pingDateRequest) throws RemoteException;
The generation of the Web service related files goes smoothly in JDeveloper 10g. The problem arises when I try to deploy this web service on the Oracle 10g (10.0.3) OC4J standalone. it gives me the following error on the OC4J console :
E:\Oracle\oc4j1003\j2ee\home\application-deployments\Sachin-TradingEngineWS-WS\
WebServices\com\sachin\tradeengine\ws\Ping_Tie.java:57: ping(java.util.Date) in com.sachin.tradeengine.ws.Ping cannot be applied to (java.util.Calendar) _result = ((com.sachin.tradeengine.ws.Ping) getTarget()).ping
(myPing_Type.getDate_1());

I read somewhere that the conversion between java to xml datatype and vice versa fails for java.util.Date, so it is better to use java.util.Calendar. When I change the code to return a java.util.Calendar then the JDeveloper prompts me the following failure:
Method Ping: the following parameter types do not have an XML Schema mapping and/or serializer specified : java.util.Calendar.
This forces me to return a String data.
I would appreciate if someone can help me out.

Hi
I got the web service working with some work around. But I am not sure it this approach would be right and good.
I started altogether afresh. I did the following step :
1. Created an Interface (Ping.java) for use in web Service as follows :
public interface Ping extends Remote{
public java.util.Date ping(java.util.Date pingDateRequest)
throws RemoteException;
2. Implemented the above interface in PingImpl.java as follows :
public class PingImpl implements Ping
public java.util.Date ping(java.util.Date pingDateRequest) throws RemoteException {
System.out.println("PingImpl: ping() return datetime = " + pingDateRequest.toString());
return pingDateRequest;
3. Compiled the above 2 java files.
4. Generated a Stateless Java Web Service with the help of JDeveloper. This time the generation was sucessful.(If I had "java.util.Calendar" in place of "java.util.Date" in the java code of the above mentioned files the web service generation would prompt me for error)
5. After the generation of Web Service, I made modification to the Ping interface and its implementing class. In both the files I replaced "java.util.Date" with "java.util.Calendar". The modified java will look as follows :
Ping.Java
=========
public interface Ping extends Remote{
public java.util.Calendar ping(java.util.Calendar pingDateRequest)
throws RemoteException;
PingImpl.Java
================
public class PingImpl implements Ping
public java.util.Calendar ping(java.util.Calendar pingDateRequest) throws RemoteException {
System.out.println("PingImpl: ping() return datetime = " + pingDateRequest.toString());
return pingDateRequest;
6. Now I recompile both the java files.
7. Withour regenerating the Web Service I deploy the Web Service on OC4j 10.0.3 from JDeveloper. This time the deployment was sucessful.(The Deployment fails if I don't follow the step 5.)
8. Now I generated a Stub from JDeveloper and accessed the stub from a client. It works fine. Here if you see the Stub code it takes java.util.Date as a parameter and returns a java.util.Date. (Mind you I am accepting a java.util.Calendar and returning the same in my Web Service interface. Step 5)
The confusing thing is the Serialization and Deserialization of Data from Client java data to Soap message and Soap message to Server java data.
From Client to SOAP :
java.util.Date to datetime
From SOAP to Server :
datetime to java.util.Calendar
From Server to SOAP :
java.util.Calendar to datetime
From SOAP to Client :
datetime to java.util.Date (I am not able to understand this part of the conversion)
Any help or inputs would be appreciated.
Thanks
