Java services

Hi,
recently i changed my company and had taken charge of the SAP servers in new company(employer).
i was exposed to windows operating systems, not much on UNIX environment.
my employer had SAP ECC 6.0 deployed on HP-UX with Oracle 10g.
here are a few simple questions, hope you people will help me in providing information which will save precious time.
1* How can i confirm wether SAP ECC 6.0, was with JAVA (i.e... java services are avaliable or not)?
2* How can i start and stop JAVA services in UNIX environment ?
3* wether ABAP+JAVA is required to access SAP by browser ?
4* If my existing SAP ECC 6.0 deployed with out JAVA, how can deploye java ? and what is the importance of this deployment ?
5* what is Jco ? and its setup in UNIX environment ? wether this will be installed along with installation of ECC 6.0 or do we have to deploye this seperately ?
6* how to establish connection from webapplication to read SAP data ?
request you to help with these bugging questions.
in windows we can find them in MMC (all the JAVA services and ICM etc) where we can check out their status, logs and start / stop those java services.
thanks in advance

> 1* How can i confirm wether SAP ECC 6.0, was with JAVA (i.e... java services are avaliable or not)?
ps -ef | grep jlaunch
> 2* How can i start and stop JAVA services in UNIX environment ?
Use SAPGUI and SMICM
> 3* wether ABAP+JAVA is required to access SAP by browser ?
?? You can use the internal ITS if you want to display the SAPGUI. All others are scenario specific questions.
> 4* If my existing SAP ECC 6.0 deployed with out JAVA, how can deploye java ? and what is the importance of this deployment ?
What is your scenario? Do you need Java for a business case?
> 5* what is Jco ? and its setup in UNIX environment ? wether this will be installed along with installation of ECC 6.0 or do we have to deploye this seperately ?
JCo is Java connector - http://service.sap.com/connectors
> 6* how to establish connection from webapplication to read SAP data ?
Which webapplication?
The question is not: When I install X what can I do with it - but rather "I have business case Y, what software do I need".

Java Services In Business Connector supported by XI ?

I am working with the java services of BC and want to convert it into XI.
My question is -the webMethods defined in the java services of BC are accepted by XI or not?
eg. the code in java services of BC is
IDataCursor pipelineCursor = pipeline.getCursor();
This line will be accepted by the XI when imported or will show error?
As (IDataCursor) is BC propriety thing.
From where the meaning of the code written in java services of BC can be obtained.
eg.
String value = configProp.getProperty(configKey, defaultConfigValue);
Here what does getProperty method do?
Thanx.

Hi,
my apologies, don't fully understand your question. Are you asking what is the XML structure that a BC Java service can consume?
If that is the question then the answer is: A BC Java service can not consume XML, it consumes IData / IValues objects.
So your question should probably be: How do we build IValues / IData objects from an InputStream?
Answer: Use a Dom or SAX parser and build the corresponding IValues / IData object maps out of that. This is accurately what we have done (+ implemented our own IValues / IData libraries so that we don't use any built-in BC classes in PI to avoid any licensing issues).
The key is to understand how IValues / IData are implemented and how to deal with XML in input / output streams.
We only use this solution internally with our BC2XI product (when requested by the customer) and unfortunately don't provide the libraries separately.
Good luck.
Cheers

How to monitor a java service in windows environment

Hi all,
I have a 5 java services running on a windows box.
I want to monitor one of those. This service is called "appnew " and appnew interacts with the oracle database.
If it is running normally the application name as seen in the task manager is "appnew running" whenever there is some runtime exception the name changes to "appnew error".
now I want to develop some external tool which can send me alert emails when we get runtime exceptions and the service name changes to
"appnew error".
I appreciate your help.
Thanks in advance.

The code you are using to change the process name to "appnew error" is the place you want to put your call to an e-mail launch.

Running a java service on linux (Redhat)

I can create a basic script to run my java service, I can stop, and restart it from the command line when logged in. I have installed the script as a service. However, when I reboot, the service will not start. I have set it to be the very last thing to start on boot-up. I'm thinking it may have something to do with the fact that when I run a java program, it does not bring me back to the command line, it just 'hangs' until it is completed, and this particular java program will obviously hang indefinitely as it is a service.
Any help would be GREATLY appreciated.
Thanks,
PAUL.

Why not start it in the background? (a trailing ampersand)
kind regards,
Jos

Intermittent problem in Coldfusion 9, BlazeDS with Java Service class and CFCProxy

If that title doesn't scare you, you might be able to help.
I believe there is a bug in Coldfusion 9's version of CFCProxy.
Tech Stack:
Flex Application
BlazeDS (stock with CF9)
Java Service class (java-amf BlazeDS endpoint)
Coldfusion business tier, invoked by the Java Service class using CFCProxy
Tomcat 6 on Java 1.6
Linux or Windows servers, both exhibit same behavior
SQL Server database
Problem:
When Flex calls a Java service method through BlazeDS that invokes a Coldfusion CFC through CFCProxy, and the method called in the Coldfusion CFC includes a large query (10 fields, 1000+ records returned), we intermittently (1 out of ~5 times) receive the following exception:

Attempts to diagnose:
These things remove the problem:
CF8 works perfectly with the identical code, never fails.
Calling the same Coldfusion CFC method with the large query (10 fields, 1000+ records returned) from another CFC 100+ times never fails.
Using a Coldfusion service class (a "my-cfamf" BlazeDS endpoint) never fails. However, we need to use a Java service class because we are using ~40 Java value objects (VOs) that correspond to ~40 auto-generated Actionscript VOs. BlazeDS won't correctly deserialize the Actionscript VOs into the Java VOs with a Coldfusion service class.
If I replace the large query with a Sleep(5000) instead, it never fails.
These things don't remove the problem:
Using the latest Microsoft JDBC driver doesn't help.
Even if the Coldfusion method returns an empty resultset (i.e., just calls the query and doesn't do any other work or return anything), the call still fails intermittently.
If the Coldfusion CFC with the method in question is instantiated and stored in SERVER scope as a singleton across multiple requests with CFCProxy, doesn't help.
Different large (1000+ record queries) all fail in the same way.
Caching the query doesn't help
Changes in the datasource configuration doesn't help
Using the older version of BlazeDS doesn't help
With all of these tests, I believe it comes down to a problem in the combination between CFCProxy and large queries. There may be more to it, but that is what we've narrowed it down to.
Any insight would be very welcome.

Workflow step (Approve Action) calling custom Java Service and "passing params"

Good Afternoon, Fellow Coders!
Normally I research and do proof of concepts until I find a solution but given super tight deadlines, I just don't have time - so I need your help.
I am trying to have an Workflow Approve Action (Workflow Exit Event idocScript call) call a Custom Component (Java Service) AND "pass" some kind of parameters (bare minimum dDocName)
In a perfect world it would be as simple as: processContentInfo(String dDocName, String xMyCode1, String xMyCode2);
But since I am calling the Java Service from idocScript (via executeService) I cannot directly pass params via the API.
Is there a simple way to do this??
It seems like if you can't directly pass params you could at least set them in the managed container (m_binder) and just know to pick them up on the Java side via some DataBinder like m_binder.getLocal(
Am I missing a simple idocScript function that will let you do this?
Note: I am NOT executing the Service from a URL so the normal ?param1&param2 -> m_binder.getLocal solution is no good.
Also, Bex's book warns about Service Classes "not easily being able to call other UCM Services".... My Custom Service needs to do exactly that (as well as JDBC and other stuff). Is this really an issue??
Seems like as long as I have dDocName I could use RIDC to hit whatever I want as long as I know how to use a binder, etc - is there some mystic nuance that prevents this? Or was he just saying it's hard UNLESS you know RIDC well??
Any and all quality advice is appreciated! And please, try to give me a detailed answer as opposed to something vague like "try a Service Handler", I need something I can quickly digest.
Thanks in advance!

You can set parameters for the service call by setting Idoc Script variables before you call executeService.
<$dDocName="TEST12345"$>
<$param1="09876"$>
<$param2="ABCDEFG"$>
These variables are then available via the service DataBinder.
Here is information about how to execute a service from a custom component. There should not be any issues doing this.

Java Service Launcher Problems

I am trying to get a java application running as a windows service. I have been using java service launcher because it is free and am unable to get the program running. It installs the service fine and if I run jsl -debug or jsl -run then the app executes fine, but if I try to start the service its reports that it cannot be started and then the service gets stuck in Starting. The app recieves messages from another server and uses this info to populate a database.
Thanks,
D

I now have the service starting but the app cant seem to connect to the remote computer. It is logging so it must be executing. I have changed the service to run as administartor and restarted the service but it still cant connect.
Thnks,

How to access AM/VO instance from a Java Service class

Hi,
I have a Java service class that is loaded by Java ServiceLoader (http://download.oracle.com/javase/6/docs/api/java/util/ServiceLoader.html) at run time, and I need to access database tables inside that service class. So is there any way that I can access AM/VO instances from that Java class in order to read database table? Thanks.
Regards,
K Hein

You can access an application module with the the two methods below:
    YOURAppModule mAM;
    public void setUpAM()
        throws NamingException
        try
            String AMDefName = "YOUR_APP_DEF_NAME";
            Hashtable env = new Hashtable(2);
            env.put(JboContext.INITIAL_CONTEXT_FACTORY, JboContext.JBO_CONTEXT_FACTORY);
            env.put(JboContext.DEPLOY_PLATFORM, JboContext.PLATFORM_LOCAL);
            ApplicationModule am = null;
            InitialContext ic = new InitialContext(env);
            ApplicationModuleHome home = (ApplicationModuleHome) ic.lookup(AMDefName);
            am = home.create();
            // Connect the AM to a database connection
            String jndiDB = "jdbc/HRDS";
            am.getTransaction().connectToDataSource(null, jndiDB, false);
            boolean connected = am.getTransaction().isConnected();
            mAM = (YOURAppModule) am;
        catch (NamingException nex)
            // do some error processing
            throw nex;
        catch (Exception eee)
            // do some error processing
            throw eee;
    public void tearDownAM()
        if (mAM != null)
            if (mAM .getTransaction().isConnected())
                mAM .getTransaction().disconnect();
                mAM .remove();
    }You find the YOUR_APP_DEF_NAME in your application module under 'Configurations' -> AppModuleJndiName.
Make sure you tear down each AM you set up. Otherwise you are running out of resources pretty fast.

Java service call from webdynpro

Hi,
Pls provide me some doc/info on how to call java service from abapwebdynpro platform.
Thanks in advance.

Call a web service isn't really a function of WDA. We have the service call wizard, but it only is a code wizard for generating the code to call a proxy class. It doesn't generate the web service proxy. There is nothing special needed for WDA to interact with Web Services. Follow the normal ABAP guides for generating web service proxies and then you can reuse this proxy class in WDA.

Calling Java Services from ABAP code

Hi,
How to call Java services (not web service) from ABAP code?
I have a requirement where JAVA team has developed some services that can be called from URL or from a Java application.
Ex: when this URL is executed,
http://localhost:8080/artemis7_802/triton/mycompany.remoteFunctions.RequirementsList.a7x?requestid=3023&requestname=I6PRAO1&skill=SAP&skill=JAVA
It returns a XML file on browser.
And I have no idea about the 2nd way i.e. from Java application!
Now, how can ABAP call these java methods?
I heard that something can be done via maintaining RFC destinations in SM59 to call Java services? Can this be done with my requirement?
Please help.
Thanks and regards,

thanx

Hi,
sounds what you want is to wag the dog with the tail. What is the use case you want to implement? Do you want to refresh a collection in response to RDBMS changes ? If so then Active Data Services is an option. However, your question is not well asked and I am already spending more time in answering your question than you spent writing it

To run a java service in SAP business connector.

Hi,
I have created one java service in SAP business connector.When i run it, i get the error as " Service 'rfctest:validatedata' is not operational. To run this service, first recompile the Java source."
I have set the "path" variable,still i am getting the same error.
What should i do to solve this problem?

Hello,
when you call a BAPI from an external system via Business Connector, you will send a bXML document to BC (for example via HTTP). Refer to the SapbcSAPAdapterGuide for how to do that in detail, its good explained (see 4-25 and 7-3) there.
The explanation about sender/receiver is not correct. sender and receiver are the logical system names of the SAP backend system and the external system (check in transaction SALE of the SAP system).
Just send such document to BC, it will create the routing rule automatically. Then complete the routing rule (see 7-2) and activate it.
