Sample JAVA code using Resource Adapter for RFC Connections

Hi Java Knowledgeable Ones.
I have successfully deployed the SAP Netweaver J2ee Engine "Resource Adapter for RFC Connections to ABAP Systems" to my Web Application Server. Now I need to develop a JAVA application that would utilize this deployed resource adapter. The resource adapter specifies the SAPClient, UserName, and password. I am thinking that the JAVA code to invoke this connection would therefore not need to provide this information as it should be available in the resource adapter.
Do you have sample code that you could send to me showing how to do this?
Thanks,
Kevin

Hi Kevin,
this is actually no good style! You should not open the connection with the adaptor knowing the password. Usually it should work via a connection that uses only basic rights and the user has already authenticated and is using his security ticket.
For security handling see:

RFC calls with SAP JCO and IBM resource adapter for SAP - basic tuning

Hi experts,
we are working on a java portal connected to a backend system SAP by calling RFCs.
On our first integration tests, it appears to be quite slow fetching data from SAP by calling the remote functions from the custom portal. We are using SAP JCo 3.0.6 and IBM resource adapter for SAP 7.0.0.3 to integrate SAP with our portal.
Is there any basic tuning to achieve to improve performances or any hint of where to tune in SAP ?
Any help would be greatly appreciated.
Thanks a lot,
Jamal

Hi Jamal,
I understand you have already checked performance issues in the SAP Server. We had some problems with certain RFC calls and it turned out to be a badly developed ABAP sentence.
I'd recommend you to use httpwatch or another tool to check the response times from the browser, so you can point accurately where the is.

Anyone tried to deploy IBM's Java resource adapter for IMS on WLS6.1sp2?

 Has anyone had success or attempted to deploy the IMS Connector
 for Java (IBM's resource adapter) on WLS6.1sp2? I would like to
 use this to connect WebLogic to IMS via IMS Connect 1.2?
 Thanks
 Sam

 Sam,
 I was wondering if you were able to use the IMN Connector RAR file. I was able
 to deploy but that was teh extent of my effort.
 Appreciate you insight!

Inqmy resource adapter for SAP with Bea Weblogic Server

 Hi everybody,
 Anybody have tried to use INQMY resource adapter for SAP with Bea weblogic server
 It works well with INQMY server, but with BEA I'm getting a lot of problems creating
 the connections.
 Thanks in advance.
 Xavi.


All,
 Here are the steps we (used for internal testing) had to perform to get
 IN-Q-MY adapter for SAP to work with WebLogic:
 The wli.adapter.inqmy.sapr3.spi package contains extensions to the
 In-Q-My J2EE Connector Architecture classes to overcome some limitations
 in the base implementation classes. To get around these issues, we had
 to extend their R3ManagedConnectionFactory, R3ConnectionManager, and
 R3ConnectionFactory classes.
 * The javax.resource.spi.ManagedConnectionFactory implementation
 does not over-ride the equals and hashCode methods correctly. This
 causes problems with WLS 6.1.
 * There is a bug in their javax.resource.spi.ConnectionManager
 implementation for non-managed uses of the adapter. Consequently, their
 adapter cannot be used in a non-managed scenario.
 * The javax.resource.cci.ConnectionFactory class does not support
 the getConnection() method that does not take any arguments (it throws a
 null pointer exception).
 I am attaching the classes discussed above.
 Cheers,
 Chris

Customizing Resource Adapter for Oracle Internet Directory

can any one give suggestion reagrding this?

Hi Bahaugab, 
I am working Oracle OID. I can able to add/modify/delete users from my resource configuration. But I am getting active sync problem with OID. It throws exception like : 
From the admin console please verify that the change log is enabled under Configuration: Replication: Supplier Settings and that the Retro Changelog Plugin is enabled under Configuration: Plug-ins: Retro Changelog Plugin
 
But change log is enabled.
 
I want to know whether your active sync worked?

Need Sample java code

Hi,
iam working in SAP .
I need sample java code on how to convert Decimal to number
For Ex: I/p-----123.11
O/p----------------12311 ( with out decimal) want to remove the dicimal point what ever the input value and deliver it to the output
Please give me code
Regards
Suman

i don't know what do you want to do really. If you are doing it simply then you can take the input in a String and then remove the decimal.
String str = "123.11";
str = str.substring(0, str.indexOf("."));
System.out.println(str);

Sample java code to obtain data from ALUI directory

Hi
I need to go to the ALUI LDAP ( directory ) services to get user profile information.
The documentation did not help me to figure out the way to obtain data from it.
so , it would be a great help if some one could share the sample java code api to obtain data from ALUI directory.

i'm guessing you are asking to get the groups for a particular user. someone in the other thread posted the actual SQL, that may be easier. ( you are on 10gR3 right, because ALUI directory didn't exist before 6.5)
I dont have a sample done yet, but the internet is filled with samples of java and ldap...

When & Why to Use WL Adapter for MQSeries as compared to MDB?

          We have a need to both send and receive message via MQSeries in asynch mode.
          Initial assessment was to receive messages via MDB and send messages by use a
          pool of Sessions to the MQ Mgr connection.
          Given this why should one use WL Adapter for MQ?
          Thanks
          Tariq.


I assume you are referring to the "WLI" adapter? Perhaps try posting
          your question to the "weblogic.integration.developer" or
          "weblogic.integration.interest" newsgroup.
          If you are referring to the "Messaging Bridge", which comes with
          WebLogic server, then the advantage is that MQ need not be up for the
          senders to continue sending. Senders can send messages to a WebLogic
          queue, which the bridge can in turn forward to an MQ queue. The
          disadvantage is that the extra bridge hop may slow down your app.
          Tom, BEA
          P.S. You are likely by now aware that WL 8.1 (just released in beta),
          can automatically pool foreign (or WebLogic) sessions for you.
          Additionallly, it provides help in that you can configure wrappers for
          foreign JMS objects. See "Accessing JMS Foreign Providers" and
          "Accessing JMS via Servlets and EJBs" listed under new features:

How run reports JDE from BPEL using the Adapter for JD Edwards OneWorld?

Hi,
I need to load on line a lot of invoices from Bpel to JD Edwards using the Adapter for JD Edwards OneWorld (iWay).
Using Business Functions as Web Services it wasn't a not good idea because of this Adapter is poorly constructed and doesn't allow simultaneous loads, a memory leak occurs on JDE server. And to load them invoice by invoice is very slow.
A choice is to use Z tables and load them through schedules, but Bpel loses total control.
I heard that I can run processes reports that enable to extract the data from the Z tables and load them into JDE.
How can I execute reports JD Edwards invoked from BPEL using the Adapter for JD Edwards OneWorld?
Thanks
Francisco
