Call Same Web Service Multiple Times
Hello All,
Just wondering if there are any issues calling the same web service more than once within a single form?
Basically what I'm trying to do is use an LDAP web service that returns a user name at different status levels. (i.e. user1 who starts the form process, and then again at user2 who is reviewing the form - pre-populating their names)
Since the web service is already bound to the first set of fields at level 1, I created a new data connection to the same web service to run at the next level. Problem is, I'm not getting any errors OR any results.
Do I need to just re-create the web service with another name?
Thanks.
Multiple calls work fine for me.
Just create a new data connection and that's it.

Problem when invoking a web service multiple times
Hello,
I have a java client which invokes an apache axis web service (deployed on an Oracle Application Server on a remote machine) multiple times.
The client distributes the web service invokes among multiple threads, every thing goes well but after an average of 300 web service invokes (among all threads) ab exception is thrown from the client:

Invoking web service multiple times
Hello,
in CAF I have modeled a business object Order which contains a number of OrderLines.
In VC I have modeled a form which is used to collect the metadata of the Order as well as a table containing the OrderLines of the regarded Order.
For storing the Order I have specified a web service in CAF, which basically inkoves the create operation of the Order.
For storing the OrderLines I have specified a web service which adds an OrderLine to a given Order (i.e., invoking the add operation on the association).
Is it possible to invoke this web service for each row in the table? When I connect the table to the web service and choose "all rows" only the last row seems to be processed.
Best regards
AlexanderHi Alexander,
Consumption of complex structure is possible when calling a web service.
Please refer to the below links:

The program which is failing is the client not the service. Can someone please provide me with some direction as to why this always fails on the third call.Hi Steven,
According to the second exception, the problem may be that the requestStream of the webservice call is null when the 3rd time the WebRequest send request to the webservice. Please debug the code and verify if it's this case. And it's better to tell us more
about the content of the text file and what the webservice does when you send request to it.

Issue in calling a web service from Apps instance

Re: Running the same (Forte) application multiple times -for different
Hi
We had the same problem - how to deploy a number of identical applications, using each their own db.
(for training).
The solution we used is to wrap the entire application into different applications by using a very small
module called KURSUS01, KURSUS02 etc, that did nothing but call the start procedure of the main app.
Then in the dbsession connect, we made a call appname to get the application name, and appended the
first 8 chars to the dbname. Thus our dbnames now points to logicals name: rdbdataKURSUS01, rdbdataKURSUS02 etc.
All this allows us to deploy the identical apps in the same env, or change one version, and run both the old
and new program on the same pc and server at the same time (eg. KURSUS01 and KURSUS02).
I also think this is a kludge - but it works nicely!

Subject: Running the same (Forte) application multiple times - for different business clients.
Hi All
We have a number of different business clients all willing to use our
application.
The (forte) application is to run on our machines etc for these (business)
clients.
All (business) clients will have their data kept in separate Oracle DBs
(instance).
The problem now is that the entire (forte) application is written using
DBSessions.
Now, depending on what business client needs to be serviced (so to speak) we
need to attach to the right DB - or use the "right" SO.
The two options we can think of are:
Option1:
Programatic change to somehow "know" what (business) client (DB) I'm talking
about and then use the right DB.
Pro:
Only one forte environment to maintain
Can run multiple (business) clients on same PC at the same time
Con:
Requires many program changes
bending O-O rules(?)
can't dynamically name SOs so can it be done at all? (ResourceMGRs maybe?)
Option2:
Use separate environments! One for each business client.
Pro:
More defined separation of app and data,
SLA-easy
Con:
Maintain "n" number of environments
Can only run the application for one environment (business client) at a time
on one PC - Big Negative here!
Not knowing any feasible solution to option 1 (without much code changes and
developer moaning) I would go for option two; as I have already worked on
multi-environment setups on VMS back at the Hydro (hi guys).
I would appreciate any comments from anyone who has solved this problem.
How, Why Pro Con etc.

I created a client from the above wsdl file using ClientGen wizard in WebLogic. This client contains the follwoing classes-
Echo.java
EchoService.java
EchoService_Impl.java
Echo_Stub.java
I created a JSP portlet and the jsp content of it is-
String url = "http://localhost:8080/SOATest/services/Echo";
Echo echo = new EchoService_Impl(url).getEcho();
getNumsResponse = echo.getNums(getNums);
I tried to call that web service from BEA weblogic portal through a JSP potlet. I got an error saying -

My web service is using soap binding. I have tested it with eclipse and other tools also. It is working well and good. But when I tried to call a web service which is created and hosted on WebLogic server(running on port : 7001), I got the correct output.
Can anyone help me out in calling a web service hosted on different server from WebLogic server.
Thanks in advance,
Tiijnar

1. The way you are invoking the WebService deployed on Tomcat server is looks suspicious. It may be valid by adding extra ?wsdl etc into the url, but still I have not seen this way to invoke the webservice.
2. So you used Weblogic ant task to generate client JARs by giving this WSDL. So looks like it generated the 4 classes (.java) and in addition any other classes for Request/Response xml objects.
3. Look at the source code of EchoService.java. It should have one default empty constructor. Internally it uses the default wsdl defined in this class. You will see another constructor that takes WSDL URL as one of the parameters (QName) etc. Echo.java is the class corresponding to the Port. In the same EchoService you should see an instance method like getEcho() something like that. This Echo.java class will have methods for all the Operations defined on this Port. So the standard code snippet we use most of the times will be like this:
EchoService myEchoService = new EchoService(); // Default it uses WSDL deployed on Tomcat at localhost:8080
Echo myEchoPort = myEchoService.getEchoPort(); // Something along these lines.
myEchoPort.xxxYYY(); // NOW this is the operation name that takes the input parameters and returns outputs defined as per the WSDL defintions. If the Input and Outputs are complex xml types, it will have corresponing .JAVA files with setters and getters.
Now if this WebService is deployed on same Tomcat but on different machine or different port, you just give the full WSDL URL with that host and port in the constructor for new EchoService(...). You may need to instantiate QName object. But look at the methods generated in EchoService.java class.
The way you are using with Impl and Stubs class may also work. I am not much famiiar with this APIs apporach. Still look at the methods generated in these classes.
Also if you latest Sun JDK 1.6, it also has one command like wsimport. Infact if you install WLS 10.3 with Sun JDK, it should have C:\beawlp103\jdk160_05\bin\wsimport command. This will also generate client jar given a WSDL URL.
Thanks

Calling a web service from within PLSQL
Hello !
I am trying to activate a web service located on a remote machine inside a database trigger . This WSDL has been generated by a XI (SAP) tool and located on the server on which the XI is installed.
XI is an EAI tool a product that is included in the SAP products - for integrating between SAP and other tools - including Oracle DB.
When I try to call the web service using UTL_HTTP package - a procedure i wrote correctly - I get the following error message :
ORA-29273: HTTP request failed
ORA-06512: at "SYS.UTL_HTTP", line 1029
ORA-12545: Connect failed because target host or object does not exist
I have GOOGLED the last message ( ORA-12545) , but the forums referred to a client for ORACLE, which is configured incorrectly; none of them referred to my case - calling a web service. BTW I tried using the web server's IP address instead of the DNS but got the same error.
Any suggestion would be very appreciated.
Best Regards,

How to call a web service from BPEL that requires HTTP basic authentication
Hi All,
I need to calling some Web Services from BPEL (SOA 10.1.3.1 production running on XP machine). The services require HTTP basic authentication.
I have tried adding httpUsername and httpPassword properties to the ParnterLink, and I see in BPEL Console that they are deployed by checking the descriptor page. But I still get a SOAP fault, HTTP 401: Unathenticated.
I have also tried using basicHeaders (from memory) = credentials, httpBasicUsername, and httpBasicPassword. Same result.
I have done a packet trace using Ethereal, and the headers do not seem to contain the userid and password at all.
Can anyone help?
Thanks,
Mark NelsonThanks Bas,
I have resolved the issue. The provider of the Web Service had not configured if for Basic Authentication. For some reason it worked when they tested, or maybe the did not test. The only thing I had to change was to use:
<property name="basicHeaders">credentials</property>
<property name="basicUsername">WMDATA</property>
<property name="basicPassword">WMDATA</property>
Instead of:
<property name="httpUsername">WMDATA</property>
<property name="httpPassword">WMDATA</property>
I don’t know why this is, maybe because it is an Axis Web Service.
Sorry for wasting your time.

Call a web service in ABAP - how to do LPCONFIG?
I have searched through OSS, SAP help and SDN - and I see the answer if I call a web service from Java - but I cannot find the answer if I call a web service through normal ABAP in R/3.
I apologize if I am asking the same question again or if it is already there and I am just overlooking it.
I am creating a client proxy in R/3 to call an outside web service through ABAP.
I create the client proxy in our test system using SE80.
I create a logical port using LPCONFIG to point at the test web service on the other system.
I code the ABAP program - and everything works great.
I transport the client proxy - and I transport the LPCONFIG information.
Now I get into production - when I do transaction LPCONFIG to change the URL of the web service to be their production web service URL instead of their test web service URL - it asks for the system to be opened.
Like it wants to create a transport. The basis people would have to open the system to be modified. Which at least in our shop is not something we do.
Here is the error:
Message no. TK430
The system administrator has set your logon client to the 'not modifiable' status.
Client-specific objects can not be changed in this client.
Contact the system administrator.
For more information, see the SAP Library under Change and Transport System.
For an ABAP program in R/3 using a client proxy - how do I call a test service in our test r/3 system and a production web service in production R/3 system without changing my ABAP code?
Should this be done through LPCONFIG?
Or what am I missing?
Thanks for your help.
Scott OvermeyerHi Scott,
Please refer to following URL
http://help.sap.com/saphelp_nw04/helpdata/en/16/285d32996b25428dc2eedf2b0eadd8/content.htm
I think you are using the second of the following 3 approaches mentioned in above documentation and so credential configuration is not available at run-time.
Please check if this is helpful to you. If you have already looked at this then please ignore this message.
There are three ways of configuring the call address of the Web service:
● As HTTP destination: Select an RFC destination of type G (HTTP connection to an external server) or type H (HTTP connection to the SAP System) from transaction SM59. The HTTP destination approves the configuration of the logon procedure, encryption, and state management. This is the preferred access procedure.
● As URL: The URL of the Web service is written to the corresponding input field when you create the logical port. The disadvantage of this procedure is that, with the exception of the URL, no other parameters for logging on, encryption, or state management can be configured. This is possible only for Web services that do not require a logon procedure, encryption, or state management.
● As local path prefix: This access procedure is only intended for accessing your own system. Here you call the default RFC destination NONE to address your own server. The specified local path prefix is used to identify the called Web service.

Call the owning VI multiple times
Hi all,
I'm trying to call the owning VI multiple times and wasn't sure if it's possible.I trying to call the same VI within a VI with different condition.
I have this VI as a template with reentrant enabled (VI_1), and inside the loop, it will call another instance of this template (call it VI_2) and wait until called VI (VI_2) completes and proceed to next action. The problem is wait until done doesn't wait although I set it to True. Can someone tell me what I'm doing wrong? or even this is possible.
Thank you in advance.
Solved!
Go to Solution.
Attachments:
VIT_Reentrant.png 18 KBSo the VI is calling itself?
If so you can drop the VI onto it's own diagram if it's set to reentrant in LabVIEW version 2009 and later.

Calling a web service reference from PL/SQL
Hello,
could anyone give me a hint how to call a web service that is defined as web service reference from a PL/SQL page process (PL/SQL anonymous block).
Many thanks in advance
Lukasz>
The problem is that I have a PL/SQL page process that processes the result that was returned by a web service (triggered by web-service page process (-; ) and <b>need to call it again transparently for the user</b>. If there is a way to execute a page process from this PL/SQL block the question would be answered as well.

Same parameters and repeating at pre-defined time intervals? If yes, use Javascript as described here.

Does any one have insights about it?Hi Swapna,
from your screenshot it seems that you actually try to call the service in your Data Source Expression field. You should set path to the WSDL file here actually - this could be either URL to SAP or to filesystem, as Anton suggested (this could be faster). Have you created endpoint binding for your service in transaction SOAMANAGER? If yes, then simply download the corresponding WSDL with binding or copy the URL which leads to it. But also test whether you are able to retrieve the WSDL without logging into SAP (close all browser windows and then open a new one otherwise session ID from other browser windows can be reused).
If you have to give username and password, then setup anonymous alias in transaction SICF, for example.
Pleas, check my previous post on the same subject here: Re: BCM7 IVR : SOAP request for client identification in CRM .
Maybe it could help.

Dawood. -
QName error while calling a web service from Sourcing
I need to call a web service from Sourcing script. The web service team has provided us the WSDL and I have generated the required stubs using wsimport and packaged the required java classes in a custom JAR. Now while calling a web method using this jar from my script, I am getting and exception. The exception message that I printed out was this:
Caught exception e with msg Connection IO Exception. Check nested exception for details. (Connection
IO Exception. Check nested exception for details. (Connection Exception; nested exception is:

The same jar and same code works fine when called from a standalone java program.
I am not using or creating QName anywhere in my script. The only place where QName is used is in the generated java class and there it is created from the correct namespace URL

What's a lightweight method to call a web service from an applet?
So, writing web service clients in java is pretty easy these days using the JAX-RPC library. Problem is in an applet you want it to load fast. I need my applet to call a web service, but don't want to include all the 'baggage' that comes along with JAX-RPC. It looks like you need XML libraries for JAX-RPC stuff to run, and those are huge jar files (many megabytes). I want a lightweight way to call web services. They are my own web services, so I don't need a general solution. There's got to be a way to just form a soap message and use http to send it. It seems like that has been done already.
On a related note. I will be passing byte arrays as parameters, so if I do try and form my own SOAP XML message, how are byte typically encoded into these messages?
Thanks a bunch for any suggestions.
MikeThe scripting prompt is due to locally installed WebHelp. If you put it on a server, it should work fine. (Or try to enable Mark of the Web for your output.)
The problem with CSH not working is probably because the CSH is not enabled in the output. In the single source layout settings, make sure that all your map files are selected:
The easiest way I see it to create a simple API yourself. (We did it for Delphi and C# and it took about ten minutes.) You can just create a URL and feed it to the default browser. If you want to be able to load new help calls in the same tab, you will have to hook into the browser somehow.
The URL's are really easy to create. See http://www.wvanweelden.eu/article-category/context-sensitivity for a complete overview of all your options in HTML and WebHelp. If you want to call a CHM context sensitive look at the following article: http://msdn.microsoft.com/en-us/library/2bk8zwb3(v=vs.90).aspx
