Web service-design

Hi,
I am developing an application which interacts with LDAP. Once I develop this application, I should have wrap the sesion bean as web service.
My questions are
(1). Do we need to represents LDAP containers as value objects? Like if the tree has Printers, Files, Accounts then shld we create PrinterValueObject, FilesValueObject ,AccountValueObject and associations?
(2). Do we have any design patterns to interact with LDAP and expose them as web service?

Wanted to understand a bit more : currently I have a command line utility which runs on PI server. I want to make a GUI verison of it (it should use same credentials as a user would use to log on to SAP) and basically send a url of this GUI to the SAP users. This will be regarded as publishing or consuming of web serives ? or is it something else?
Secondly ,I have PI 7.1 with EHP 1 : how will I accomplish this process?
If you could provide details ,it would be appreciated.
Thank you

Errors when compiling the web service (SAP Web Service Design Tool)

After downloading and installing the SAP de Web Service Design Tool (for Crystal Reports Server) I created a connection, a simple query and was able to deploy a web services. I tested the web service with an Xcelsius dashboard within InfoView. Thereafter I created a second connection (other name but same ODBC connection / server) and created another simple query with two date(range) parameters and a group by year and month function in order to do a select count(). It executes fine, but when I try to publish the web service I get an error.
There are errors when compiling the web service.
Is does not say whatu2019s wrong or how I can solve this problem.
Who can help me?
Some notes:
1) Within expert mode I used a MONTH() SQL function which does not show in the normal mode.
2) It seams that the u2018administrationu2019 of Web Service Design Tool got u2018corruptedu2019 after only creating the two connections, queries and services mentioned above. I believe so because I could select one of two queries when I created the second service, but within the current connection I had only one query.
Thanks for any help,
Ron
ADDITIONAL INFO: The parameters seam to be the problem. After removing the parameters I can publish the service. But without parameters it is NO SOLOTION.

Hello Taylan,
I think the error that you received was due to packaging issues.I placed the
UtilClass.java file under a directory called data which was present under
the project directory.
When you want to access a java class, you can either place the compiled
class file in the WEB-INF/classes folder or you can place the java file
under the project directory.
I have attached the sample project that I created with your files.
Let me know if you have any other questions.
Thanks

Hi,
I was also getting same error once...However i was able to see my web service definition in F4. Selecting from F4 list was working fine but if i entered the name mannually, i was getting the same message as you got...may be its a Bug..
Just to assist you, Have to activated the webservice from SICF before going for deployment using template or Adobe ?
Just check if you have maintained the webservice in SICF.
Thanks & Regards,

A web service design question

Hello,
I�d like to ask for your help in the following design issue:
I need to create an email sending web service (with Axis). Only just one method which returns with an integer return code. This handles the following:
- based on the given parameters gets the email addresses from an
LDAP server (with netscape ldap for java)
-     makes a cache from them (only after a timeout period will be the cache
refreshed) (don�t know what tool to use for this)
-     selects html templates which to be sent based on the given parameters
-     sends emails with the appropriate templates (with Velocity)
-     the whole process is logged (with log4j)
I have to write the code as generic as possible. I know that some design pattern should be used for this. (some from GoF , and I know there exists design patterns specially created for web services as well).
Could you enumerate me which patterns (and for what part of the program) would be the best choice to solve this problem? I have read through some books about patterns, but don�t have the knowledge to pick up the right one for a concrete problem like this..
Thank you in advance,
nagybaly

This sounds like a known issue which is tracked in ADAPT01103681. Code from a .NET DataProvider is executed twice if the provider has input parameters.
At this time there's no known solution for this. This was submitted to the development team and a fix is expected in Service Pack 2. At this time we have not announced a release date for SP2.

Hello,

issue:
I need to create an email sending web service (with
Axis). Only just one method which returns with an
integer return code. This handles the following:Lots of responsibilities here. You would do well to break this up into several classes that you can test separately.
I would also advise that you not embed all this in a servlet. Make a service that collaborates with several objects to accomplish the task and let the serlvet just call it.
.> - based on the given parameters gets the email
addresses from an
LDAP server (with netscape ldap for java)I'd recommend Spring's LDAP module. Pretty terrific stuff.
cache from them (only after a timeout period will be
the cache
refreshed) (don�t know what tool to use for
this)Maybe EhCache or OsCache or something like that.

the given parametersWhere does this come from? Certainly not the LDAP. A relational database? Write a DAO for the document template.

-     the whole process is logged (with log4j)Easily done.
I have to write the code as generic as possible. I
know that some design pattern should be used for

Stop thinking patterns and start thinking objects.

Web service design question

we have to create a web service that will be deployed to oas 10.1.3.0
the web service has to consume a lot of parameters describing a membership iof a motorclub. the incoming data has to be validated and if all the validations pass, stored in the database. we already have some logic implemented in plsql, but the code cannot be reused completely because some rules get changed for the project. a membership can have 0-n associates
what would be a preferable approach (performance, flexibility, maintenance, etc) to design such an application:
1. create a stored procedure that consumes an sql object and wrap it into a web service using jpublisher or jdev wizard
or
2. design the wsdl and create the web service using top->down approach, use O-R mapping framework (toplink or jpa) to insert data into the underlying tables.
thank you

Hi,
actually from a data perspective it doesn't matter if you display the app on iPad or smart phone. The Service could be easily build with EJB and ADF BC (your choice as both support nested objects (for ADF BC you need to ensure you set it on the view link as explained in the documentation)). Here are some design considerations
1. expose a method on the service that takes an input argument for the order to display (usually Long or Integer)
2. The service should return a collection (List)
3. The compoent on the mobile to allow master/detail views is the list item. In your case though you only have a single master record (order) and multiple detail records so that I would a read only form for the order and a panelList for the details. On click on a detail item in the list you can then navigate to the detailed detail information

Web service design trade-offs (TCP read mode vs headers)

If I use HTTP headers, I can stimulate and monitor my LV RT code from a web browser while my PC-based LV code is also talking to the LV RT app. Sometimes, however, the header is the only part that is returned by the web service. In order to fix this occasional nuisance, the headers can be eliminated so that the Read TCP data in Immediate mode doesn't exit when only the header has been returned. Unfortunately, the browser interface (in native, non-JavaScript mode) doesn't work any longer so hitting a simple URL request is useless.
Has anyone found a way to get reliable comms with HTTP headers turned on without having to parse the entire return string line-by-line?

Yes, it failed during insert using AL2.0.1.
So the above statement produces the following error message:
The symbol "" was ignored.
ORA-06550: line 2, column 74:

Note how the error is reported to be a column 74 on line 2, yet line 2 of the above block should only have 58 characters, so at a pure guess somehow there's extra whitespace on line 2, that is confusing the PL/SQL compiler, I suggest re-typing the PL/SQL handler manually and seeing if that cures the problem.

Web services design issues.... for a newbie

I have to develop several web services (JDev 9.0.2.822 and 9iAS R2). Almost all examples that can be downloaded from OTN expose simple web services that user java datatype like strings, ints and the like. In my case, the web services I should develop transfer custom information which are modeled as value classes or entity EJB's in my app. We deal with complex objects which contain collections/arrays/lists of other objects, and although most of the bussiness logic of the app is exposed via stateless session beanss and clases, I can not select their nethods since there ar no custom serializers for them.
By reviewing the sample newsfeed web service I noticed that int their implementation they decided to "hard-code" the data by doing an XML-query to the db and constructing a custom XML document. this document is returned as a java string so the web-service is, at the end a very simple one, which uses no custom serializers. Of course there is code to create the XML doc, and there should be some XML parsing at the client in order to deserialize the XML into java in order to do something with it.
My question is, is this the "preferred" method to deal with custom complex datatypes. should I include code in my beans and value classes so they "serialize" itself to XML so my web services have to deal with simple java strings? I have no experience in developing serializers, and I can't see why they are used? I am not sure which path should I follow, for example, should I use an array serializer to serialize a collection/array of object or should I better develop a method which will create a custom XML document repesenting the array? Are there any trade-off?
I have to start development right away, so please give me some insinght.
Thanks,
Fedro.

Yes, Oracle9iAS is currently production on 9.0.2. The target for OC4J 9.0.3 was end of summer but I have not seen it arrive yet. It is supposed to work in conjunction with 9.0.2 - i.e. you can use the OC4J 9.0.3 with the rest of your Oracle9iAS implementation. I think you are reasonably safe assuming it will be here by year end. I sit on the JDev side of the house so don't have specifics on what their actual delivery dates are but would guess sometime during September. The developer preview of OC4J 9.0.3 is currently available here on OTN as per the headline in the Web services Center at: http://otn.oracle.com/tech/webservices.
There are two big advantages of OC4J 9.0.3:
1. Interoperability testing ... it has been put through the SOAPBuilder's interoperability tests and includes a test suite for you to try it out 9.0.2 is fine here but you have evidence in 9.0.3;
2. Feature/functionality - support for Web services based on JMS, document style Web service support, testing harness at the end-point, J2EE 1.3 certification, custom serialization support (not there in 9.0.2), cleaner PL/SQL based Web services and more - see:
http://otn.oracle.com/products/ias/daily/jul22.html
The development environment that goes along with it is JDeveloper 9.0.3. While OC4J 9.02/9.03 comes with what is called the Web services assembly tool for those who like scripting/command-driven approaches, JDev puts a traditional visual dev environment on top of the OC4J 9.0.3 environment (and also Apache SOAP 2.2/2.3.1, incidently) The developer preview of JDev 9.03 is due out within days here on OTN ... probably Tuesday based on what I understand. JDev 9.0.3 production is scheduled to arrive probably in late September mid-October.
Hope this gives some background to help with your decision.

How can I test my Query As A Web Service?

Hi,guru:
    I have created my Web Service based on universe which based on SAP BW query using Query As A Web Service Designer, but when I use it in Dashboard on BOBJ platform by passing a parameter to the Web Service, it seems no response from the Server,I made 2 test steps:
    1.Pass a value to the input parameter,I checked by ST01 in BW Server and see no records of the action, and no result return.
    2.Pass a blank to the input parameter,I checked by ST01 in BW Server and got many records,and all data be retrived.
    It seems that when I passed the parameter,the Web Service seems no response and didn't run at all. Is there anybody who can tell me how can I test the Web Service,I want to test it and input my parameter.
    Thanks very much for your quick response.
Best Regards

Transport Webi Reports and Web services as the backend of dashboards from BO Production to BO Development system

Hello Experts,
I am working on SAP BO 4.1. I have made several dashboards on top of web services ie;Web Service Method. I have 2 systems in BO ie; Development and Production Systems.The BW production system is connected to BO Development and Production both.
The Webi reports are made on top of BI BEx Query. From the webi reports, BI Web Services are made on top of which the dashboards are made further.
The Webi Reports, Web Services and the Dashboards everything is made directly in BO Production.
My question is, Can I transport the Webi Reports and the Web Services from BO Production to BO Development?
And If yes, will it have any other impact on webi reports, web services or dashboards?
Thanks & Regards,
Alfred Thomas

Hi Gill,
As per your reply,with the promotion managament i have make the web services again manually in Dev system...Right?
Is there any way possible that i can transport the webservices and the webi reports usind Query AS A Web Service Designer. And if yes, through this QAAWS will the WSDL or the URL required for the web services in the connection button in dashboards will automatically updated or changed as per the Development System?
But i am not able to enable the "Deploy to Other servers Option" in QAAWS.

Hello, I am attempting to write a dashboard that will retrieve data from a database using the GetXML, I have tried many other methods but this seems the only one I can get working.
The issue I have is that in my code it returns only one selecatble parameter and stores the whole entires within it.
Below is an example of the code.
I send from the dashboard the Xcelsius_Value and it returns the xml schema as expected with fieldnames but within one selectable parameter and does not allow splitting into different cells.

Query as a Web Service can't see .unx universes to use as data source?

I created a Universe using Information Designer. The Universe is published on the server as *.unx.
With Query as a Web Service Designer, I connect to the server to create a query. However, in "Choose a universe as a data source for the query", I do not see the *.unx Universes, I only see *.unv Universes.
Both software are the latest version (XI 4.0).
Anyone know what is the issue here?

Unable to deserialize HTTP response content - SharePoint Designer Call Web Service Workflow Activity

I am creating a workflow using SharePoint Designer 2013 and I'm using the call HTTP web service action.
The web service call works (it is for a text messaging service, and I get the text message to my phone) however the workflow stops at this point with internal status "suspended" and gives the error message below when clicking on the "i"
icon.
I have tried setting the Accept and Content-Type request headers to "application/json; odata=verbose" (minus the quote marks) as other posts suggested but this doesn't make a difference (e.g. here: https://social.msdn.microsoft.com/Forums/windowsapps/en-US/f0b18411-87d1-466b-aab0-1a0093605ed4/workflow-cannot-read-json-after-latest-sp15-patches?forum=sharepointdevelopment).
I tried adding in the Content-Length header too but that made no difference.
I tested calling another web service (https://sharepointurl/_api/contextinfo) and this works fine.
Is there any way to get the workflow to accept this XML as the response? I don't actually really need anything out of the response content, but I do need the workflow to carry on after this step and carry out other activities after this call.
Error message:
