How to use Webservice in Webdynpro ABAP?

I tried searching option for importing WSDL file in WebDynpro ABAP. But I am unable to upload it in my component. In service call wizard I can see only one option i.e. to import Function module.
We cant use Webservice in ABAP webdynpro?
Thanks
Nitesh Shelar

Thanks Rich for quick answer.
But my problem is, I have a stand alone WAS without any RFC Function modules and dictionary structures, of backend R/3, on WAS which I wanted to map in my component.
I strongly believe that in case of stand alone WAS I need to have at least backend dictionary structures to begin with my design. I cant use wizard, as I dont have function modules on this system. I have to code for that manually..
So that is why, I was looking for Webservice option..
Thanks,
Nitesh Shelar.

How to compile and run a Java servlet using the BEA weblogic server

          Hi,
          Could you help me out as to how to compile a servlet using Web Logic server.I have written a Servlet program and have also set up the environment in the "c:\bea\wlserver6.0\config\examples" folder by giving the command setExamplesEnv.cmd.
          I have stored my GreetingServlet.java file in "c:\bea\wlserver6.0\samples\examples\servlets" folder.
          How do I compile my servlet now?
          Vid


Hello,
1. The .form file was used by Netbean's GUI builder to create the .java and is not needed for compilation.
2..../src # javac -classpath "..." mytool/*.java
I guess the package mytool was not coped with.
Alternatively it is worth to use the ant build tool also used by Netbeans.
Then you can make a jar from the class files, indicate in the manifest.mf file:
1. the main class
2. the library jars

How to call java program from ABAP

Thanks.

This depends on the version of your Netweaver Java AS. If you are running 7.0, you will have to use the Jco framework. The Jco framework is deprecated since 7.1 though. If you want to build a RFC server in 7.1 or higher, it is adviced that you set it up through JRA.
Implement an RFC server in 7.0:

How to call java function in javascript

Hello Everyone,
Can anyone tell me solution that:
How to call java function in javascript?
Thanks,
VIDs

You can't since Java is running on the server and javascript is running in the browser long after the Java side of things has finished executing. Assuming you're not talking about an applet here.
But you can make calls back to the server through Ajax. All you need is something like a servlet on the receiving end which you can invoke through Ajax; from that point you can execute any Java code you want.

How to call a webService from WebDynPro ABAP ?

We are trying to call a webService from WebDynPro-ABAP application. It is not working, While if we are calling the WebService from a Report, it is working.
How exactly do we call a WebService from a WebDynPro-ABAP application?
What are the main steps involved ?

Hi Phani,
You will need to create a service call as follows.
Right click on your WD component name and select Create->Service Call
The wizard will guide you through a series of steps to make a Web Service Call. On the 3rd screen, it will give you options such as Function Module, Web Service, etc
Before making a service call, you will need to create a proxy for the Web service in the ABAP Workbench using a WSDL document as a basis. To create or consume Web services, you will need the authorizations associated with the role SAP_BC_WEBSERVICE_ADMIN.

How to call java method from workflow script?

Hi
I have a requirement of updating field value 'Document Status' based on review/approve of content from Workflow and hence need to update the version number. For that I need to call my java method from workflow during submit of review/approve condition. Please let me know how to call java method from workflow?
Is there any alternative better way to achive this requirement from workflow? Please suggest.
Thanks,
Sarang

OK. So, I think we can all conclude that you don't need to call any Java method, can't we? And, that wfUpdateMetadata is the command that will update your metadata.
Now, the question is what are its arguments. It has two - the first is the name of a custom metadata field to be updated (let's suppose that one field is called xMinorVersion, and the other xMajorVersion), the other is the new value, e.g. <$wfUpdateMetaData("xMinorVersion", "New value.")$>As for new value - do you insist on using strings? Since you want to increase the value, it would be more convenient to work with numbers. For instance, with integers you could go with <$wfUpdateMetaData("xMinorVersion", xMinorVersion + 1)$>With strings you will need to convert it to numbers and back to strings. Besides, what happens if you have more than 100 minor versions? (you mentioned you want to add 0.01, but that would finally increase the major version, wouldn't it?) So, I think these two numbers are independent (perhaps, with exception that increase on the major version set the minor version to .00).
If you want to present it, you can use profiles that will construct for you the representation 2.304 out of MajorVersion = 2, MinorVersion = 304
Solved?

How to call Java API from BSP?

I have a requirement to call Java API from BSP application.
I have checked the forum and found that it is possible by using some ABAP codes.
However there is no pointer on how this is done.
Can someone explain the details on how to call Java API from BSP is done?
I found class CL_EJB_JAVA_OBJECT_METHODS to call a method in EJB but can't find function or SAP class to call Java API.
Actually is there any BSP extention which can used to call Java API?
Thanks,
Hendri

check out these weblogs, it should give you an idea how to go about it.
