Calling Java API from ABAP using JCo (Part 2)

Hello,
This is an additional question to thread Calling Java API from ABAP using JCo
Has anyone managed to get the input parameter value
input.getString("REQUTEXT")
that is being passed from ABAP?
If yes, what kind of setting you need to do? Because when I execute, it has no value.
Thus, the below ECHOTEXT parameter returns blank value:
output.setValue(input.getString("REQUTEXT"),"ECHOTEXT");
When I debug by printing the below line, the input XML is indeed without value:
System.out.println(input.toXML());
Anybody knows how to pass input variable from ABAP to JAVA using JCo?
rgs,
hiroshi

Hallo Hiroshi,
as far as I can see, you are doing it the right way. The problem might be that the ABAP program does not fill in this parameter because something went wrong in the SAP System.
Have you tried setting a breakpoint (an HTTP session - remote breakpoint) and tried checking step by step if the value is being processed and put into the REQUTEXT field?
Bye,
Sameer

Calling Java API from ABAP using JCo

I need to call Java API from ABAP & BSP also. For this I have got useful information related to JCo from following blog:
/people/gregor.wolf3/blog/2004/08/26/setup-and-test-sap-java-connector-outbound-connection
But, I am facing one problem. On executing Java program myExample5.java (recommended by Gregor Wolf) from command line I get following error message:
Server JCOSERVER01 changed state from [ STOPPED ] to [ STARTED ]
Exception in server JCOSERVER01:
com.sap.mw.jco.JCO$Exception: (129) JCO_ERROR_SERVER_STARTUP: Server startup failed at Thu Apr 26 13:46:32 IST 2007.
This is caused by either a) erroneous server settings, b) the backend system has
been shutdown, c) network problems. Will try next startup in 1 seconds.
Connect to SAP gateway failed

Can anyone please help me out. Do I need to do any setting?
I'll surely reward points.
Thanks & Regards,
Nilesh Kumar

Hi Nilesh,
From the error i think that the error is with the hostname.
Please enter the the Application Server IP/Hostname.
If you are loggin to SAP System "XX1" from SAP GUI. Then click the change Item tab and see Application server name/IP let say "XX2" for hostname or "xx.xx.xx.xx" for IP.
Replace srv[0] = new Server("gateway","sapgw00","JCOSERVER01",repository);
with srv[0] = new Server("XX2","sapgw00","JCOSERVER01",repository);
If App Server is IP then replace with
srv[0] = new Server("xx.xx.xx.xx","sapgw00","JCOSERVER01",repository);
Let me know if it is throwing any error.
Thanks,
Prashil

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.

Calling java APIs from a function module

Hi,
Can someone tell me whether it is possible to call Java APIs from a function module in SAP system?
Thanks in advance,
Vineetha

Hi,
I guess you have changed the properties of screen only.
I assume you have made a Ztransaction Code.
When you define a transaction code, you need to specify a screen number for radio option program and screen and you need to specify a screen and not subscreen.( I think so!!)
You changed only the code without changing the transaction code properties.
Therefore, i think u r getting a dump.
If you want to call your subscreen, call it in some screen and then call that screen using your transaction code properties.
To include a subscreen screen in the subscreen area of the main screen and call its PBO flow logic, use the following statement in the PBO event of the main screen:
PROCESS BEFORE OUTPUT.
CALL SUBSCREEN <area> INCLUDING <prog> <dynp>.
To call the PAI flow logic of the subscreen screen, use the following statement in the PAI flow logic of the main screen:
PROCESS AFTER INPUT.
CALL SUBSCREEN <area>.

Calling Java API from HBR

Hi guys,
I’m trying to use Java API to update ASO cube from Planning forms. So there are several steps:
1.     Planning form passes variables to HBR
2.     HBR passes variables and calls Java CDF
3.     CDF performs some operations and uses JAPI classes to update ASO cube.
When I run CDF as runtime command or from JDeveloper/Netbeans if works fine. When I run CDF from HBR but do not use JAVA API methods it works too. But when I call CDF from HBR AND use JAPI methods it doesn’t execute JAPI methods. I do not receive any error; methods that use JAPI methods are simply not executed.
Any ideas why it happens?
Thanks,
Dmitry

Hi,
Have you tried running it from an essbase calc script first and run the essbase server in the foreground (not as a service if you are on windows) then if you have any System.out.prints on errors or in your code they should be outputted to the window.
It usually easier to get it running from a calc script first because you sometimes get better messaging than business rules.
Cheers

How to call Java API

Hi,
Currently I am getting inputs from another composite, lets say Composite A and in composite B I need to pass the input values ( approx 40 elements are coming from composite A) to Java API ( end system). I have jar file for java API which has 20 different classes. Can you guys suggest me how to map the input values that are coming from composite A to Java API.
I developed a Bpel process which receives the input from Composite A. Please suggest me for next steps and procedure to follow.
Thanks.

I would look into using the Spring component and wrapping your java api in a simple sprint bean class. SOA will then generate WSDL's and do marshalling/unmarshalling of the data between your BPEL and the spring component automatically. It will just look like another service call from within the BPEL but will actually invoke your spring component.
Thanks,

Calling Java APIs from Adobe AIR Front End

HI ,
I have developed an desktop application entirely in java.
Currently it is console based, but i am planning to have a UI for the same in Adobe Flex.
I wanted to know how do I communicate between the two, ie call methods that are defined in my java classes from AIR and return results to Adobe AIR.
There is no server involved.
I want to keep Adobe AIR as front end and Java as back end which will take care of the business logic .
Thanks and Regards,
Santoshi

The best way is probably to use the NativeProcess APIs available in AIR 2 (now in Beta).
Next, would be to use sockets to communicate between the two processes. In AIR 1.5, it is difficult to guarantee that both processes are running, at least when controlling thins from the AIR side rather than the Java side. In AIR 2, you can start other processes, so this is also easier.
There are some 3rd party tools, like Merapi, that help you pass objects between Java and AIR, too.

How to call Java API classes from Javafx Main.fx?

Hi
Can anybody let me know how to include java.util.StringTokenizer in Main.fx file of Javafx?
I need to split a concatenated String in Javafx. Is there any example available with anybody on this?
When I use the split() of Javafx, I get error while assigning the value returned by split() to both String and String[] variables:
1. var name = "test|string";
2. var names: String[];
3. var splitName: String = "";
4. names[0] = name.split("|");
5. splitName = names.split("|");
6. var storeName: String[];
Later I need to put the splitName into another String array to have a collection of all the concatenated string in one array.
insert splitName into storeName;
But I get error in line 4 and 5. The split() in javafx returns a String []. Is there anything that I missing here.
Any reply to this post will be highly appreciated. I need this quite urgently.
Thanks & Regards

Java API for Error Handling

There are some common error tables storing error IDs information ( IDs like error type, project id, interface id, message id etc.) in Operational Database (is not on source or target system) which we have to update using java API. We need to call java API (java code) whenever error occurs. We have to provide all the IDs to this function and then API will take care of DB updating. We can call java API in mapping program by creating user-defined java function, this will trap all the errors which are in source file as well as in mapping and mapping lookup. Query is:
A- A- Do we have any other place after the mapping to call this java API and trap the errors through it?
B- Can we call Java API using BPM and pass error IDs to it.

Hi Anand,
You Have to write Module For that(if you wanna call Java API after Mapping)at the receiver.
To write Module Here is a link which will help you in.....

Call Java Program from ABAP Program

Dear all,
In our scenario, we need to let ABAP call services provided by a standalone Java program. From online help I found some overview introduction and I'd make the called program a registered program in a RFC with type "T" (TCP/IP Connection). Can anybody give some concrete documentation? A step-by-step guide would be greatly appreciated.
Best Regards
Jerome

Anybody has experience calling ID API web service in Java

Hello,
as you know we can programmatically update ID objects by call ID APIs (web service). To do that you need to import the wsdl into a java project, generate web service client and call the client to update ID objects.
I've tried this in NWDS CE version. However I got error when generating web service client from the wsdl of the ID web service. Only the BusinessComponentService passed the ws client genertion, the rest web services do not work.
The error I got:
IWAB0399E Error in generating Java from WSDL: java.lang.NullPointerException
java.lang.NullPointerException
at org.apache.axis.wsdl.toJava.JavaInterfaceWriter.writeOperation(JavaInterfaceWriter.java:126)
Anybody has experience with ID API?
Thanks
Jayson

HI Jayson,
you can also request the web service directly.
For example, you could create a local xml file with the values you want to pass to the web service and configure a file 2 soap scenario within XI itself.
You can create interfaces for each available web service.
You could call this scenario "ID objects generator" or something and save the .tpz for the repository objects of this scenario, since you could reuse it in other projects.
Other than that, in Teched '08, Bill Li showed a lot of proxies developed over Java to consume the ID API web services, and they all seemed to work ok. However I do think he used NW Developers Studio 7.0 (2004s), not CE.
I'd raise an OSS msg with SAP in order to check the problem you're getting.
Regards,
Henrique.

Call a Java API inside a java mapping

Hi,
I have a web service in SAP PI 7.0 that recives a PDF coded in base64. I need to call an external Java API provided by a partner for extract its digital signature and return it as Web Service Response. It's possible to do the call to a Java API inside a Java mapping for doing this? What is necessari for doing this call?
I think that I Need to install the Java libraries in SAP J2EE stack and import its inside the java mapping. Need I something else?
can you show me any exemple?
thanks.

Hi,
Put your jar files on your servers java path. Doing so you can have direct access into an udf for your libraries.
Another option (for testing purposes is a good idea) is to attach to the scenario your jar file. Go to mapping objects, imported archives, and import your jar file there. By this way it will be visible only on the context of the software component and namespace where you put the file.
Regards.
