About those 500 enterprise web services

Hello,
I'm new to SAP and interested in developing apps atop NetWeaver. In his webcasts Shai often refers to "500 enterprise web services" (or something similar). Where are these services documented and how can I get ahold of this document?
Thanks,

Hello Douglass,
have a look at <a href="https://esapreview.sap.com/socoview(bD1kZSZjPTgwMCZkPW1pbiZ3PTkzNzAwMDAr)/enterpriseservices.asp?$SMCPACKAGEID$">Enterprise Services Index</a>. On the SDN Website you find them via ESA -> ESA Preview System -> <a href="https://www.sdn.sap.com/sdn/index.sdn?page=ESP/home.htm">Enterprise Services Preview</a>.

The below document should help you.
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/3f6cd467-0301-0010-b099-8bea6d075978
At the same time take a look at this link.
https://www.sdn.sap.com/sdn/index.sdn?page=ESP/home.htm
This works for me. However in order to access the system you should request and get the access.
On the other hand if you have mySAP ERP, you should have the services. Go to SE80 and execute the BSP application "WebServiceBrowser" and you should be able to see the list of services.

No WSDL Validation at Application Level for Enterprise Web Services

Hello community,
We are building Enterprise Web Services in our application running on Netweaver 7.40 and have built several service definitions through the Enterprise Service Builder tool.   Ultimately the WSDL file that the builder creates is mapped to Java skeleton classes which define the API for the service endpoints thanks to Netweaver Developer Studios' 'Generate Java Bean Skeleton' functionality.    What we noticed was that during the processing of requests, the application was ignoring all validation imposed/defined in the WSDL definition.
We're assuming that this type of validation is part of an operating Web Service implementation on any J2EE Application Container - including Netweaver - and the Container would be responsible for early validation stages of request processing, utilizing the Service definitions.
Is it not part of the JSR-921 specification that compliant applications include a SOAP Processor that parses and validates a SOAP request that is submitted?   Where It is part of the responsibility of the SOAP processor upon receiving a Service request to validate and THEN relay the request to the appropriate Service method?
We could potentially validate our own but we have 100's of objects to manually validate against which becomes a very tedious and hard to maintain exercise.   It seems redundant and common behavior that should be handled at the Service layer by the SOAP processor within the Container should it not?
Validation capabilities seem to be provided by other vendor products such as Oracle AS and WebSphere.    Does anyone know if Netweaver offers this and if so how would we go about implementing it through configuration or otherwise?
Thank you!
Hanif

Hi,
If WSNavigator is not asking for password then endpoint is not configured for user/password so go ahead and use this wsdl in .Net application, it should work fine,
Just make sure that session is not stored in WSNavigator and that's why it is not asking for user/password. I believe if you open wsdl with binding it should ask for user/password.

Enterprise web service for CREMAS

Is there an SAP delivered Enterprise web service to create vendor data in ECC ?

Dear Umesh,
Unfortunately my experience is bound only to axis2, but i think there will be not big differences on what you want to do.
As i know there are two ways, by-value and by-ref,(and an other one combining the two previous) to make an attachment. The first one is:
a) by-value solution
<?xml blablabla?>
<root>
<my_elem1 name='xyz'>
<type>car</type>
<image>101010101010101010101001010101010100101</image>
</myelem1>
<root/>
This can be made with 'hand'... Meaning what you should do is this(client side):
                OMFactory fac = OMAbstractFactory.getOMFactory();
          OMNamespace omNs = fac.createOMNamespace("http://you.com","xsd");
          OMElement method = fac.createOMElement("my_elem1", omNs);
                OMElement value1 = fac.createOMElement("image", null);//<image> ....    </image>
          value1.addChild(fac.createOMText(value1, ImageData ));//                   /\ server side:
public void myserviceMethod(OMElement payload){
              OMElement oe1=payload.getFirstChildWithName(new QName("http://you.com","image"));
              DataBase.store(   oe1.getText()    );//this is the binary stream(10101010101010101010)
}b,c) I don't think it make sense(at this point) to describe the other two because i thing they will confuse toy and they wont help you find a solution to your problem(its better start with the first one).

Determine BADI from Enterprise Web Service?

Hi all,
We've just started to work with Enterprise Web Services and have a need to enhance one of them. Using ES Workplace we have identified the 'Read Purchase Order' as a candidate and want to see what capabilities exist in making minor changes. The resources that we have found so far that detail this involve implementing a BADI.
My question is, how do we determine what the BADI is for each enterprise web service? I do not see a BADI name listed in the es workplace page for the web service. Is there a tcode on the ECC system that can use one of the values listed from the es workplace page?
http://esworkplace.sap.com/socoview(bD1lbiZjPTAwMSZkPW1pbg==)/render.asp?packageid=DE0426DD9B0249F19515001A64D3F462&id=32D255D472EA11DA36BB000F20DAC9EF

Hello,
BADI's relevant for each Web Service is provided at ES Workplace. For example, PO Query Web service definition ECC_PURCHASEORDER002QR, BADI is PUR_SE_PURCHASEORDER002QR which is mentioned in the link:
http://esworkplace.sap.com/socoview(bD1lbiZjPTAwMSZkPW1pbg==)/render.asp?packageid=DE0426DD9B0249F19515001A64D3F462&id=32D255D472EA11DA36BB000F20DAC9EF
I hope you may also search BADI's in SE18 using wild search 'PURCHASEORDER002QR'.
Thanks,
Venu

SSO using spnego set up but not working for an Enterprise Web Service

Hello, I am looking for some guidance. I have a function module that is exposed as a web service. I am trying to be able to access the web service with sso so the user does not need to logon. Systems has set up SSO using spnego to issue sap login tickets on our dual stack and sso is working if I try to access a netweaver link such as http://mycompany:8001/nwa but it is not working when I try to access my service
http://mycompany.com:8001/sap/bc/srt/rfc/sap/myservice/500/myservice/myservice. I am wondering why this would not work and if it is possible to use sso with enterprise services?
Thanks for any help...we have been stuck for a while now.

Examples about ABAP Proxies and Web Services creation

Hi everybody.
I have been reading SAP NW PI 7.1 help about Web Service creation and sincerely, I am a bit confused. Also I have searched SDN forums, blogs and documents but my confusion persist.
I will try to depict my integration scenario below.
SLD are conformed by two machines: SAP ECC 6.0 system, client 100 and SAP PI 7.1 system, client 001.
There are two integration scenarios.
1. ABAP Client Proxy -> PI -> Web Service
I need to consume a Web Service provided by a third part. They provided me with WSDL files and I imported them into ESR. I already construted all other objects (data types, message types, etc.). In the examples I found I cann't see what to do with those definitions, I don't find any suitable example. This is an asynchronous scenario. The Web Service will be consumed from SAP ECC 6.0 system through an ABAP Cliente Proxy.
2. Web Service -> PI -> ABAP Server Proxy
I need to provide a Web Service for others to consume it. I already have created the WSDL for Service Interface I created in ESR using the respective wizard in Integration Builder. This is an asynchronous scenario. The Web Service will be consumed by others outside landscape configuration. When the Web Service is consumed must run an ABAP Server Proxy.
In spite of my investigation about Web Services building in SAP NW PI 7.1 I cann't finish my work successfully.
I just need a good example, any suitable example for each integration scenario.
Thanks in advance.
Rafael Rojas.

Hi,
1. ABAP Client Proxy -> PI -> Web Service
1. Create all necessary objects in ESR
2. Create integration scenario objects with PROXY as sender SOAP or WS adapter as receiver
3. Create client proxy in your SAP backend using SPROXY
4. Create ABAP client proxy to execute the proxy which then will call your PI runtime to execute the webservice.
2. Web Service -> PI -> ABAP Server Proxy
1. Create your necessary objects in ESR
2. Generate server proxy in your back end system
3. Create integration scenario objects with PROXY as receiver and SOAP or WS adapter as sender
4. Generate WSDL from integration scenario and pass it to your partner.
You can find many blogs which discuss these steps in more detail.

Lim...

Newbie question about the viability of web services.

Hello All,
I have never dealt with web services, and have only cursory knowledge of the technology, so forgive my ignorance in advance.
I have a situation that I wonder if Web Services might help me solve.
I have built a Java/JSP application that resides on a server that is inside our firewall. It has been successful, and management wants to make the data and functionality available to our customers outside the firewall.
The problem is that our organization tightly controls the "public" applications. And the UI for my system does not meet their standards. Nor will they punch a hole in the firewall to allow access to my server.
The solution we have been working on is to create a new UI using their approved methods, and copy the needed java classes to the "public" server.
As you can see, if I do this, I will have to maintain two instances of the same class on two different servers.
Can I avoid this by using web services to make those classes available to other applications from my internal server?
Thanks in advance for your help.
James.

The solution we have been working on is to create a
new UI using their approved methods, and copy the
needed java classes to the "public" server.
As you can see, if I do this, I will have to maintain
two instances of the same class on two different
servers. Okay, first, yes - webservices can help you if you MUST maintain two seperate UI's for some reason using the same backend data code or if you want to provide a datafeed only to your external users. It will take care of having to maintain seperate but identical class files, but it will create other overhead such as interfacing the existing files and the like, but if you must enable the UI then you will have two versions of this to maintain. If you are looking to just enable the data feeds and not the UI then it would seem a very logical fit.
If you must maintain the UI, then why can't you convert your app over to the approved UI and host it on the "public" server for all users (internal and external)? Then you only have one set of data to maintain - period and webservices aren't necessary. If you proceed with either your current implementation or even with a webservices based implementation, you will have at least two seperate UI's to maintain as well as whatever the resulting support code - be it webservice interfaces to existing code or replicates of existing code - to also maintain.

Getting information about configured(webservices.xml) web service handlers

Hi Guys, The situation is: In a Web Service, I have few GenericHandlers configured as server(Role) in webservices.xml(for IBM Runtime) & server-config.wsdd(Axis Runtime). Say the handlers are A, B & C. Now, when there is a inbound call A,B & C are getting invoked as expected.
I am basically lookin for a way to know (programmatically) the # of handler configured for this web service i.e., 3 in this case and few other handler specific details.
I was investigating getting hold hold of HandlerChain by following way
HandlerRegistry hndlReg = service.getHandlerRegistry(); List hChain = hndlReg.getHandlerChain(new QName("http://test.com","PortName"));
, but I dont get hChain containing information about A,B or C. Ya, here I can add Handlers programmetically which gets invoked also. But no information of already configured handlers in configuration files.
Is there any way(programmetically) to get the details about already configured handlers.
Appreciating your help.

Please help ....

Short question about networking, Threads and web services..

Lets say I got 2 classes, Midlet A and Thread B.
I created Thread B because web services (jsr-172) uses networking and It has to be done in a separate thread other then the Midlet A.
So, in Thread B, I have the run(), where I do all my stuff, and some getSomething() methods.
I need to have run() complete before calling getSomething(), so I used something like this in Midlet A:
while(true){
if(b.isAlive())
getSomething();
}Problem is, Thread B only runs to completion when I don't call b.isAlive(). (I know from System.out.println I placed in it) When I do use any methods like wait() or join() or isAlive(), Thread B stops at the web service call.
I really don't understand what's the problem. I've tried various ways to only call getSomething() when the thread finishes running, but all of them made my WTK emulator hang at the part where it asks for permission to access the network.
If I don't use getSomething(), which is the purpose of starting the thread in the first place, it runs fine in the emulator and doesn't hang anywhere. Oh the irony.

Bump!
Anyone got even half a clue what's wrong? =O
Hmm. I think that having the midlet wait for the thread causes the midlet to hang because the thread will then wait for the midlet for permission to access the network, but the midlet is waiting for the thread to finish it's code. Damn.

Question about the distribution of web service or servlet

I don not know how to distribute a web servcie or servlet on the web server. I can only use this web service with the open state of the glassfish. If I close the glassfish server, the servlet cannot be accessed.
I just want the web service or the servlet to be disributed on the web server. Web service and the servlet are available when the web server is on.
anybody can help me?
thank you in advance.

About XML Parameter for Web Service invoking

I would like to use the XML parameter as the Web Service's input(Attachment is
the XML schema) in WebLogic Server 8 sp1. When I generated the Web Service and
use the WebLogic Server generate test web page to test it, I got Exception. The
WebLogic Server can't constructe the input XML.
The correct XML should look like this:
<ids>
<desc>Description</desc>
<id>1</id>
<id>2</id>
<id>3</id>
</ids>
Is there any one can tell me whether this kind of XML was permitted for Web Service
invoking or not?
[sample.xsd]

Hi Andy,
On the test page, before the invoke of the operation, did it say
something like:

if so, the service itself may be working OK, the deficiency is that the
test page tries its best to determine sample values for the invoke,
however it does not know in this case.
Did you try with a client?
Your XML should be fine.

Bruce

Hello.
For example, build.xml is in the folder:
d:\jwsdp_tutorial\docs\tutorial\examples\gs\build.xml
Then write a bat-file in the same folder that looks like this:
-------------------- BEGIN --------------------
set JAVA_HOME=d:/j2sdk1.4.1
set ANT_HOME=d:/jakarta-ant-1.5.1
set CATALINA_HOME=d:/jakarta-tomcat-4.1.18
