Multiple web services or one with many methods? when are threads created?

Hey guys,
I was just wondering how do you implement your web services - if you create one wsdl location with many methods (meaning one @WebService and lots of @WebMethod), or leave one class for each method, having many wsdl locations.
A follow-up question would be: does each web service call create a thread, even if it's different calls to the same web service?
Thanks for answering.

Hi,
pure from a coder instinct I think I would prefer them to be in separate projects for better reuse and clean separation. If I need project 1 to access aclass from Project 2, I can check the dependency check box in the project properties. Is there any business requirement that makes you think having all of these in a single project will help ?

Btw.: I agree that JDeveloper shouldn't constraint developers from doing what they want and if this is a limitation the feel free to file a bug

Multiple Web Services in one Jdeveloper project

Hi all,
I'm currently trying to implement a series of web services, all relating to one application. I'm using the top-down approach, where I generate the web service from a WSDL file, and add my implementation to the generated classes. The WSDL file imports all sorts of XML Schemas (xsd-files) and Jdeveloper correctly generates all the necessary java-classes for me. Lets call the first web service I create WS-1.
This all works fine and I'm a happy panda. I can call the web service, it works, I can modif the wsdl and regenerate the web service to e.g. change the input etc. All this works.
Just until the point where I want to create a second web service (lets call this WS-2). This new web service doesn't use all the XML Schemas that the first web service does, it is more simple with regards to in-/output. The problem arises when I modify WS-2 and Jdeveloper regenerates the Web service files (.java and the files in the WEB-INF/wsdl-directory). When I do this, it deletes the imported xsd-files that WS-1 uses (removes them from WEB-INF/wsdl).
And when I regenerate WS-1 to get my xsd-files in again, then when I regenerate WS-2 it imports all the unnecessary xsd-files into the wsdl for WS-2.
Something tells me, that there is a connection or shared library between all web services in one Jdeveloper project. That they all imports and uses the xsd-files in WEB-INF/wsdl.
Is this true? Can't I have multiple web services (and wsdl-files) using different types (schema definitions) in the the same Jdeveloper project?
One solution I can think of, is to have all my web services in different projects under the same application. But is this really necessary?
I'm using Jdeveloper 10.1.3.3.0.

Is it possible to define multiple web services in one project?

I'd like to publish multiple components within one project as web services. but when I try to create it using the project New menu, it only prompts me and allows me to select one component . So does this mean only one web service can exist in one project?

Sunil
Thanks for the prompt reply.
I think I should have worded my question more clearly.
I have a project with multiple Java classes. I'd like to convert two of them into web services.
There are two ways to co this.
1. I right click on each class and select the Generate J2EE Web Service option. This will work correctly and allow multiple web services to be generated.
but this is not what I want to do .
What we are trying to do is to generate web services at the project level. I am following instructions in OTN web services tutorial :
http://www.oracle.com/technology/obe/obe1013jdev/ws/wsandascontrol.htm
So , this is what I do :
1. Right-click on my project and select New from the context menu.
2. In the New Gallery, expand Business Tier in the Categories list and select Web Services, then select Java Web Service from the Items list. Click OK.
3. In the Select J2EE Web Service Version dialog, select J2EE 1.4 (JAX-RPC) Web Service, then click OK.
4. Click past the welcome page
5. This brings me to the page where I can select the web service and class.
This is where I am stuck - it seems I can only select one web service here . Unless I am missing something.
Or should I just repeat the process multiple times - running the wizard once for each class ?
Thanks for the help.

Bad response in a Web Service on OC4J with many concurrrent clients

We have a Web Service in a OC4J container, this Web Services invoke the business services from another complex application (another ear with EJBs in the same container) with RMI connections.
We need this web service support many concurrent clients, but in our tests the performance is very bad, the web service supports ten concurrent clients in a long response time for all of them, (for one client the Web Service responses in 3 seconds / for 10 clients in 45 seconds) if we test with 20 concurrent clients, the web service can´t process at least 15 requests , the other 5 finish well
What can I do to improve the performance with many concurrent clients (100 +)

Hello,
I am quite surprised...
Could you please give us more information about your environment and behavior:
1- which version of oracleAS, WS and J2EE are you using?
2- do you have any information in the application log about possible source of error?
3- Any information about performance of the different layers?
Can you simplify the flow by creating the service in the same EAR than the EJB and void RMI calls for example?

Certificate error while connecting to multiple web service

I am having a web service test client through which I can connects and get reports from multiple web services.
In Development unix box, we are using "self-signed certificate" using keystore type JKS. In Production server, we are using certificate from CA.
The web service is running in Development and in Production.
Now I have developed single test client with a drop down selection for different web services. For example, if we select "Development", the request will go the development web service and if we select "Production", the request will go to Production web service.
Now while connecting to Develpment service, we are settings the below certificates details Because we are using the self signed certificate.
System.setProperty("javax.net.ssl.keyStore",keyStoreFileLocation);
System.setProperty("javax.net.ssl.keyStorePassword",keyStorePassword);
System.setProperty("javax.net.ssl.keyStoreType", keyStoreType);
System.setProperty("javax.net.ssl.trustStoreType",trustStoreType);
System.setProperty("javax.net.ssl.trustStore",trustStoreFileLocation);
System.setProperty("javax.net.ssl.trustStorePassword",trustStorePassword);
I am clearing the System properties using the System.clearProperty() while pointing to Production service. because in Production we are using the CA certificate from Thawte so these details are not required at all and our JRE (java 5) is pre configured to support that CA certificate.
I am using Resin-2.1.12, axis1.2 and java5.
Now the problem is
(1) for the first time, when I send the request to Production Service URL, the report gets generated. For the next time when we are running against Development, it's giving below certificate error.
sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
(2) Now restart resin and run the test client against Developemnt service URL, here report gets generated and for the next time, run the test client against Production, it's giving the certificate error.
So for the 2nd request, it always gives the error irrespective of the web service instance selected.
Please suggest ....thanks in advance.

Hi ,
No, due to the issue is happening only on one computer.
The error "(401) Unauthorized" usually indicates that the connection has been established but the permission check fails. InfoPath Form Services uses the application pool identity of the web
application to connect to resources.
Does the account which login the computer have permission to connect to User Profile Service Application?
For a workaround, you can go to IIS Manager , set the User Profile Application Pool to Anonymous Access and try again.
Also you can have a look at the blog:

Combine multiple web services with the same SQL query into one

Hello,
I would like to ask a question regarding combine multiple similar web services into one. Can you please tell me if it is possible to combine 4-5 web services into one since they built on the same SQL query with 5 different criterias or condition so that the user can enter any of the 5 criterias to populate the data on the form instead of having 5 different web services?
e.g Query: Select appName, permit#, address, phone, description, type, section, from table where appName = can be 'appName, permit#, address, phone, or description' to populate the rest of the data to the form.
Does any one have ever done some thing like this in Workbench ES? If so please assist. I know it can be easier to build it in Visual Basic, C#, or dot.net but the requirement is to build it in workbench ES.
Thanks in advance,
Han Dao

If you are querying for Name, PhoneNumber, and SSN, and you queried for all people with a phone number that started with 867, you would have a potentially long list of people. So to keep track of all of the people, we store each record in XML complex elements. The root node is just any name you want, and the repeating element is the complex element name.
So using the example from above, I'm going to specify the following:
     Root Node: Result
     Repeating Element: Person
So now when I do a query, my resultXML will look like:
<Result>
      <Person>
             <Name>Alex</Name>
             <PhoneNumber>867-5309</PhoneNumber>
             <SSN>111-11-1111</SSN>
      </Person>
</Result>
If your query returned multiple results (like ours would probably), it would look like:
<Result>
      <Person>
             <Name>Alex</Name>
             <PhoneNumber>867-5309</PhoneNumber>
             <SSN>111-11-1111</SSN>
      </Person>
      <Person>
             <Name>Han</Name>
             <PhoneNumber>867-2169</PhoneNumber>
             <SSN>222-22-2222</SSN>
      </Person>
</Result>
So Result and Person is just to give a little bit of structure to the xml result (containers really). So you can name them whatever is helpful for you.
The column name mappings map the query columns (Name, PhoneNumber, SSN) to some node in the XML (Name, PhoneNumber, SSN). So you don't need to specify which field maps to what in the form. Just copy the column names to the element name so you have a 1-to-1 naming. If you want to manipulate the XML a bit though, you could do:
Column Name               Element
Name                            YourName
PhoneNumber                Phone
SSN                              Secret
which would then make your xml look like:
<Result>
      <Person>
             <YourName>Alex</YourName>
             <Phone>867-5309</Phone>
             <Secret>111-11-1111</Secret>
      </Person>
</Result>
It lets you change the XML element names to whatever you want. Otherwise by default they take on their column names.
In your form, you could bind to the WSDL through the Data Connections pane and point it to your web service. This will then create form elements that you can just drag and drop allowing you to have the information available when the service gets ran. Once the service is called, you can modify the field's data to get whatever information you need in order to populate other form fields.
If that is too confusing, feel free to send me your form (e-mail is on profile page) and I'll add comments to it to show you how to set up the form for the web service call (and also give me the link to your webservice)

OWSM and Webservices -Define policies once for multiple web services

I thought that through using OWSM we had the possibility to use the same Policy Lines for multiple web services.
Mostly when web services are used/integrated within an application, the same rules need to be defined and I thought this requirement could be met when using OWSM.
But you need to define the policy requirements on each web service that's passing through a gateway or agent, why isn't it supported to define policy lines one level higher to be able to use the same requirements for multiple web services?

Nathalie,
For this purpose OWSM allows you to use Template Policy Pipelines.
For individual services, you can than replace the pipeline with the Template.
But I have to agree with you here: the templating functions are rough on the edges, e.g. limited editing capabilities.
Hope this helps.

Can't have multiple Web Service connections in SP1

Hello,
I'm currently interested in adding more than 1 Web Service connection to a particular xcelsius file, but after adding the first connection, the option is disabled in the Data Manager screen. Is there a workaround for this, since before service pack 1 you could have any amount of connections and as off upgrading this was changed.
Regards

Yeah I totally agree, It's like someone giving you a bunch of new appliances for your home but then telling you that your not going to have any electricity. This product is pretty much usless to me now.
Just the thought of having to partially develop in one version of xcelsius and then port over to a version that has SP1 installed makes me ill. From what I can tell Xcelsius Engage Server still has multiple web service connection functionality enabled (http://www.businessobjects.com/product/catalog/xcelsius_engage/comparison.asp), I'm interested to see what the cost will be to upgrade to Server.

What's wrong? Any idea?

Web Services to communicate with ALSB from ABAP

Hi Experts,
I Have a requirement where i need to call ALSB(aqua logic service bus) from an ABAP RFC function module using web services. I have to send one XML file to this proxy service .I have same idea about web services.I have gone thru help.sap.com for this web services . But, I am not sure on how to include the logic for calling this web service in my function module. What are the inputs we should get from this proxy service to establish a web services connection? Can anyone help me out?
Regards,
Lakshman.

To get the process started, go to SE80 TCODE
From the Enterprise Services Tab, we are going to select Client Proxy and then hit new create button.
select WSDL
Generate the proxy class
activate it and use it.
PI stands for Process Integration which can be used as central repository/registry for all the enterprise services ,using PI u can provide or consume the services.
