Calling XI interfaces via Java

Hi All,
What is the method to call a Interface in XI via Java?
Regards,
Keerti

are you talking about Java Proxy ?
You can connect to an external Java based system via a Java proxy (XI adapter) - http://help.sap.com/saphelp_nw04/helpdata/en/e1/091640a991c742e10000000a1550b0/content.htm

How to call Jakarta Ant via JAVA?

Hi.
My application has a new menu. This menu creates a build.xml Ant file.
Now, when this menu is invoked , its action should call
Jakarta Ant, after creating the xml file, so that the build.xml will
do what is necessary.
How can I do it? That is, how to call the Ant via java?
Is there any way to use an Ant object?
Thanks?
Rodrigo Pimenta Carvalho.

There is a slight problem in that
PorjectHelper.configureProject is deprecated, but
that is what Main calls...maybe someone else will
complete this thread with an alternative call.The javadoc recommends using the non static method parse() instead. This is available by implementing class ProjectHelperImpl. An alternative to the code above might look like this:
        Project ant = new Project();
        ProjectHelper helper = new ProjectHelperImpl();
        ant.init();
        helper.parse(ant, new File("build.xml"));
        ant.executeTarget("clean");you might also want to add a logger so you can see the output of events generated by ant. The DefaultLogger class would be used like this. Simply add the code before you call the ant.init().
        DefaultLogger log = new DefaultLogger();
        log.setErrorPrintStream(System.err);
        log.setOutputPrintStream(System.out);
        log.setMessageOutputLevel(Project.MSG_INFO);
        ant.addBuildListener(log);

Can I call an interface from java

Dear All,
Can I call an interface from java in ODI ?
Best Regards
Arc

Short answer, Yes.
Long answer - you must create a scenario from the interface (the scenario is the "executable" code), right-mouse-button on the interface in the tree and "Generate Scenario". This can then be called using the invocation api this is documented in your <installationdirectry>/oracledi/doc/sdk/invocation. This points you at all the necessary classes etc to use.

Calling stored procedure via java

Hi all,
i have a problem calling a stored procedure in my java code. I found an example at OTN which seems not to be correct. I know there had been a lot of posting regarding this isue but i did not find the solution.
I had the following VB-code to translate to java:
Set k = Server.CreateObject("ADODB.command")
With k
.activeconnection = Db
.CommandType = 4
.CommandText = "Get_SK"
Set vret = .createparameter("vRet", 131, 2) 'Output
.Parameters.append vret
.Execute
End With
In my java code:
CallableStatement sproc_stmt = null;
try {
sproc_stmt = lsession.connection().prepareCall("{ ? = call TCSDBOWNER.Get_SK}");
sproc_stmt.registerOutParameter(1,OracleTypes.NUMERIC);
sproc_stmt.setFetchSize(10);
sproc_stmt.execute();
The call generates an id for inserting new rows in the DB. executing the code shown above i got the following error:
wrong number or types of parameter/arguments
Is there anybody who can help me? Best regards,
ak

I use Jdev 10.1.3.2 and generated the WS proxy, everything looks good. Then I go into the generated client and add in the following code:
public static void main(String[] args) {
try {
cmswstest.proxy.CMSPortClient myPort = new cmswstest.proxy.CMSPortClient();
System.out.println("calling " + myPort.getEndpoint());
DataImportXMLRequest dr = new DataImportXMLRequest();
String tmpXML =
"<?xml version = '1.0' encoding = 'UTF-8' standalone = 'yes'?>" +
"<CMS_CURR_INFO_UPD>" +
"<MSG_SEQ_NO>NATX_ 0000000000000200706201337193</MSG_SEQ_NO>" + "</CMS_CURR_INFO_UPD>";
byte[] xmlb = tmpXML.getBytes();
dr.setUserName("elmarm");
dr.setUserPass("fud567");
dr.setXmlData(xmlb);
DataImportXMLReply repl = myPort.dataImportXML(dr);
System.out.println("Length of XML message = " + repl.get_return());
// Add your own code here
} catch (Exception ex) {
ex.printStackTrace();
When I run the client, I get the following error message:

Any ideas as to how to debug the situation. As is quite obvious, my experience with WS and SOAP is minimal at best :)
Thanks for all the help.
PS: I tried the same thing in Jdev 10.1.2 and got the following error:

Hi Vid,
To be able to deploy Doc-literal Web services on 10.1.2, you have to select the J2EE 1.3 type of web services when you create the first Web Service of a project. Once you have create a 1.4 service, the dialogue is not displayed again for the given project.
The other source you have is correct. the JAXRPC based type of Web service that is generated with JDeveloper 10.1.3 cannot be deployed on 10.1.2, as the new runtime is not available there.
One way to get a Doc-lit service on 10.1.2 is described in Mike's blog [1]. THe WSDL file generated in 10.1.3 is a good start, as it will enable an easier migration to 10.1.3, once it's available.
Hope this Helps,
Eric

Calling C++ functions by Java via CORBA?

Hello,
I am interested in source code examples of calling C++ functions by Java via CORBA. For example the client is in Java and the server is in C++. Is it posible that the IDL compiler can generate "java" client stubs and "c++" server sceleton? So the implementation of the client will "inherit" the stubs generated by the IDL compiler, and the server implementation will use the sceleton.
Thank you in advance.

As far as I know, you've got to have your idl on both side. You compile idl mapping to java on client side and mapping to C++ on server side. Then you should be able to do it.

Calling to BPM via PI

Basically I have already found a solution by trial and error, but I still don't understand what's going on, maybe someone can help me understand.
I am trying to make a web service call
from a CRM system (CRM 7.0 EhP3 SP 3), outbound interface {http://sap.com/xi/CRM/FS/Global2}NewLoanBoardingFSCreateRequest_Out
via PI (double-stack, PI 7.31 SP 3)
to a NW Java BPM system (NW 7.40 SP 4, inbound interface {http://sap.com/xi/FS-AO/Global}NewLoanBoardingProcessingNewLBrdngIn. The host name of the system is ilbnknw1 and the port is 50300.
I created an EJB for the implementation of the service provider NewLoanBoardingProcessingNewLBrdngIn and a BPM process according to note 1891861 in NW Developer Studio and deployed all of it to the NW Java BPM server.
There is a web service end point for NewLoanBoardingProcessingNewLBrdngIn on the NW Java BPM server the URL looks like this: http://ilbnknw1:50300/bpm/testsapcom/polnlbv0/start?wsdl&mode=ws_policy (visible in WS Administrator > Configuration > Connectivity > Single Service Administration > (stay on tab Service Definitions) > search for WSDL Port Type Name: NewLoanBoardingProcessingNewLBrdngIn ... I don't remember if it was created automatically during the deployment or I created it manually.)
The security settings for the end point are set like this:
Transport protocol: HTTP (not HTTPs)
HTTP Authentication: Checkmarks for Login with User ID/Password and for Logon ticket are set. (X.509 is not set and also grayed out.)
Message Authentication: No checkmarks are set.
I can test the above WSDL URL (http://ilbnknw1:50300/bpm/testsapcom/polnlbv0/start?wsdl&mode=ws_policy) from WS Navigator and it works - I don't get an error message, and in WS Administrator I see that the process is started (at Operations > Processes and Tasks > Manage Processes).
Now I wanted to test it from CRM. One possibility would be to go into SOAMANAGER and create a port that connects to the end point. But we prefer to go via PI. So I set up a receiver determination, interface determination and receiver agreement. The first two have no problems, the correct receiver (a business system referring to the NW Java BPM system) and the correct receiver interface are found. With the receiver agreement I was not so sure what to do and I tried different things.
First I thought: It's a call to a web service, let me use a web service receiver channel, i.e. Adapter Type = WS of version SAP BASIS 7.31 (I tried 7.40 because the NW Java BPM server is 7.40, but the PI doesn't like that because it's only 7.31).
I entered:
WSDL Access URL: I used the complete URL (http://ilbnknw1:50300/bpm/testsapcom/polnlbv0/start?wsdl&mode=ws_policy).
Authentication Method for WSDL Access: Basic Authentication using HTTP. (The other option No authentication and SSO using SAP Assertion ticket don't seem to fit.)
User name for WSDL access: A user in the NW Java BPM system.
Password for WSDL access: Password of the user
Security
Communication Security: None
Authentication Method: User ID/Password (Transport Channel Authentication)
Technical Transport Settings
Target Host: ilbnknw1
Service Name/Port: 50300
URL Access Path: /bpm/testsapcom/polnlbv0/start (this can be selected with the value help button and that was the only choice int he value help)
Then in the receiver agreement I chose this channel and entered the user and password on the NW Java system that should be used for the actual WS call (while the other one in the channel is only for accessing the WSDL) ... actually I used the same user and password for both, it has enough authorizations.
Result: Didn't work at all, PI showed a red flag for the message with the error WS_ADAPTER_SYS_ERROR and text System error while calling Web service adapter: Error when initializing SOAP client application: 'Error when initializing SOAP client application: "SRT: Unexpected failure in SOAP processing occurre"'
Question: Is this totally the wrong adapter to call to a NW Java system, or were my parameters wrong?
Then I found some things in the forum that said: Just use SOAP adapter, not WS adapter! And for communication between (newer releases of) PI and (new releases of) NW Java BPM it's best to use the SOAP adapter with the XI 3.0 protocol.
So I tried a SOAP receiver channel with XI 3.0 protocol, i.e. Adapter type SOAP with version SAP BASIS 7.31,
Transport Protocol: HTTP,
Message Protocol: change from SOAP 1.1 to XI 3.0,
Adressing Type: URL address (HTTP destination was the alternative),
Target URL: I used the whole URL (http://ilbnknw1:50300/bpm/testsapcom/polnlbv0/start?wsdl&mode=ws_policy),
Authentication Mode: Use Logon Data for Non-SAP system (because Logon Data for SAP system wanted a client and language, so I think it refers to ABAP systems only),
User Name: A user in the NW Java BPM system,
User Password: the matching password
(No settings in receiver agreement, just chose the channel.)
Result: The PI didn't show any error anymore, the flag was black-white. But on NW Administrator (Operations > Processes and Tasks > Manage Processes) I could not see the process starting!
Question: How is this possible? Where else could the error be seen? Are my parameters wrong? Probably not, otherwise PI should already show the error.
Next try: SOAP receiver channel with SOAP 1.1 protocol, i.e. Adapter type SOAP with version SAP BASIS 7.31,
Transport Protocol: HTTP,
Message Protocol: SOAP 1.1 (the default, instead of XI 3.0 in the previous attempt)
Adressing Type: URL address (HTTP destination was the alternative),
Target URL: I used the URL just up to the ? for the parameters, i.e. only http://ilbnknw1:50300/bpm/testsapcom/polnlbv0/start,
Checkmark for Configure User Authentication,
User Name: A user in the NW Java BPM system,
User Password: the matching password
At the bottom:
Checkmark for Use Query String,
SOAP Action: wsdl&mode=ws_policy
(No settings in receiver agreement, just chose the channel.)
Result: Success in PI (black-white flag) - and now two processes were started shortly after each other (within 15 seconds)!
I tested again to see if it would always trigger two process starts, but now it only started one as expected.
So it looks like the other process start "pushed out" a hanging previous process start? Is such a thing possible? Where could I monitor this? (Apparently not in NW Administrator > Operations > Processes and Tasks > Manage Processes).
So now I have a solution, I use a SOAP receiver channel with SOAP 1.1 protocol, not with XI 3.0 protocol, and certainly not thw WS adapter. But I still wonder why it's not working with the XI 3.0 protocol, even though this seems to be the most recommended way for PI and BPM to communicate in recent releases that support this, and what exactly happened there, where the first process start was "hiding" in the meantime.

Hi Monika,
did you choose the URL
http(s)://<hostname>:<port>/MessagingSystem/receive/JPR/XI
in the XI 3.0 communication channel as described in the SAP Help? As far as I understand your description you didn't. Maybe this is the reason that it was not working with XI 3.0.
Please check this link for proper setup:

Calling EJB facades via class instantiated via reflection?

We are loading plugins via Java reflection. Anything instantiated via newInstance() does not appear to have access to the Local interface.
Right now, to get to the session bean we must use the Remote interface. This is annoying due to the performance, and seems completely unnecessary when everything is operating in one JVM.
Tests were done to print out the JNDI namespace and the local interfaces don't seem to be accessible. Any advice?

My project consists of an EJB package and WAR. I have not had any problem calling the local facades from JSP, Servlet, or web service in the EJB package.
Further, I can use XStream reflection and do local EJB calls.
It baffles me why I can't do the local calls in some classes via InitialContext lookups.
I will post test code next week.

What is the diffrence between My Runnable Interface and Java Runnable

Hi folks
all we know that interfaces in java just a decleration for methods and variables.
so my Question is why when i create an interface its name is "Runnable" and i declared a method called "run" inside it.then when i implements this interface with any class don't do the thread operation but when i implement the java.lang.Runnable the thread is going fine.
so what is the diffrence between My Runnable Interface and Java Runnable?
thnx

Hi folks
all we know that interfaces in java just a decleration
for methods and variables.
so my Question is why when i create an interface its
name is "Runnable" and i declared a method called
"run" inside it.then when i implements this interface
with any class don't do the thread operation but when
i implement the java.lang.Runnable the thread is going
fine.
so what is the diffrence between My Runnable Interface
and Java Runnable?
thnxClasses and interfaces are not identified by just their "name", like Runnable. The actual "name" the compiler uses is java.lang.Runnable. So even if you duplicate the Runnable interface in your own package, it's not the same as far as the compiler is concerned, because it's in a different package.
Try importing both java.util.* and java.awt.* (which both have a class or interface named List), and then try to compile List myList = new ArrayList();

Need Info Regarding Implementaion of Interfaces in java.sql package

Hi All,
I am interested in knowing details abt how the Interfaces in the java.sql package are implemented. We all work with the database using the interfaces provided ,but how do they work at the backend ? How can a Interface provide details (work ) with out an implementation class.I Is this taken care by the JVM or some of the Call level interfaces? Please do provide details abt this..

hi Sheshadri,
The implementation of the various interfaces in
java.sql package are provided by your jdbc driver,
which also manages the connection and communication of
your java program with the appropriate database.
cheers,

"ORA-29532: Java call terminated by uncaught Java exception

Dear Oracle:
I am trying to establish an HTTPS connection from a Java stored
procedure that is wrapped in a PL/SQL procedure and loaded into a
Package. We are running on Oracle 8.1.7.
My Java code compiles and runs fine when run stand-alone outside
Oracle; I can establish the connection to a secure server and talk to
the server. However when I load this Java class (using the loadjava
utility) this class can no longer run and I get a the following
exception:
"ORA-29532: Java call terminated by uncaught Java exception:
javax.net.ssl.SSLException: SSL handshake failed:
X509CertChainIncompleteErr"
I have tried loading the JSSE from Sun and I still get the same error.
Searching in the Discussing Forums I found the following link (which
describes a procedure that logs into the UPS secure server site and
grabs some XML) http://osi.oracle.com/~mbpierma/SSL_Java_DB.html .
This code works ok if we try to connect to UPS server. However this
code doesn't work if we try to log in to a different server (such as
???). If I modify this code slightly and try to log to any other
sever server I get the same error as the one above. Investigation
lead us to understand that the certificate at the UPS web site is a
self-signed certificate -- not one generated by a major 'recognized'
authority such as Verisign or Thawte.
Further research pointed me to the following URL
http://www.znow.com/sales/oracle/network.816/a76932/appf_ora.htm#619367
This URL has the documentation for JAVA SSL for 8.1.6 which I figure
I could read and try to make it work in 8.1.7.
I looked at your Secure Hello World example, however the code is
missing the most critical parts of the whole example, it does not
specify where the certificate or any of the security settings come
from (see the attached JavaCertExample.txt file).
So, my questions are the following:
1) What should I do to avoid the error mentioned above?
2) Do you have a sample piece of code that describes how to make a
HTTPS connection using a Java stored procedure?
3) Can I make the HTTPS connection using a URL class and not using
sockets directly?
4) Do I need to load the JSEE provided by Sun?
5) Will the solution be different for Oracle 9i?

Hi,
I have the same problem.
Is some ORACLE guru that can help us ?
We need to communicate with some servlet
via POST method of https (SSL3)
and with using private certificate on the client site.
We need furthermore allow using of some proxy.
Client site is realized as set of stored procedures within ORACLE 8.1.7
In this time I am able to communicate with server without SSL and certificate
using package utl_tcp
(but with this solution without certificate is our customer not satisfied -:))
ORACLE help us please !

Interfaces in Java

I have a doubt about interfaces. All interface in Java has empty methods, I mean,the methods dont have any implementation. So, to use these methods, there has to be a class that implements this interface in order these methods to have an implementation. Here is my question: there are some Interfaces in Java like java.sql.Statement that dont have any class that implements its methods and in spite of this, I can call the methods of the interface. How is this possible?
Thanks

Yes there is always an implementation. You just aren't necessarily exposed to the actual class which implements the interface, but you can tell what the class is like this:
Statement stmt = ...; // get your Statement however you are doing it now
System.out.println("Actual class implementing Statement interface in this case is: " + stmt.getClass());
