Trying to develop a JCA connector

Hi
I'�ve a package that allow applications connect to an IBM host using sockets and 3270 telnet protocol.
I want to isolate and standarize such layer using JCA to run it as a resource adapter in an application server.
I'm new to jca and reading specification is drivin me a little bit confused. I' ve "googled" for sample code but the few I found are simple db resource adapters implementations so I wonder if some one could point me to a non db jca samples... or guides/books about this matter.
I've found this sample code:
http://java.sun.com/developer/technicalArticles/J2EE/connectorclient/resourceadapter.html
but the article is similar to those I've read but I'm still confused.
I know I need to wrap my EIS connector with my resource adapter but what I couldn�t see clear is where should I do it.
I supposed that it should be in the lower layer, the connection implementation, but all the sample codes I saw make and instance of this class but recommend to put the EIS code in the managedconnection class.
I've a simple class called CICSSocket that make the connection with EIS and with two methods read and write to allow those operation the EIS throw sockets and a open method to open the socket.
If make an instance of CICSSocket in the Connection class constructor, it will be a wrapper but I'll be returning a Connection instance, not a CICSSocket instance, so how the AS or the client will call CICSSockets methods ? How the AS could pass parameters to CICSSocket to make the connection ?
What happen if I do the above in the ManagedConnection class as I saw in various samples ? How will it work to wrap my class ?
So, I've a clear map of all but I really don't understand how all components interact and how to do it and couldn�t found real samples about it.
Could somebody please send me a simple sample code or explanation to make me see the light ?
Thanks in advance

please next time use BI Publisher
But when the data is less than 65500 rows layout is coming proper without any warning.
IMHO it's ok
excel has some limitations
( 65,536 rows per sheet. )
no ideas how to check/read report with >65k rows
as idea
you can try to split data into some sheet
need more info about your report and logic and how bip is usead like eps part, obiee part etc

Error while deploying JCA connector :-

Hi,
Im trying to deploy a JCA connector to WebLogic 9.1.
The same connector deployed fine to WebLogic 8.1, but throws the following exception now at 9.1 :-

Hello Swarna:
I believe than rather than deploying the MDM4J.jar, you should deploy this components:
com.sap.mdm.tech.mdm4j.sda
com.sap.mdm.tech.connector.sda
BPMDMTECHN00_0.sca
BPMDMAPPLI00_0.sca
Once you deploy those, you should have no problems. Another solution would be to take your MDM4J.jar and wrap it into an SDA, then deploy, but that would be pretty much the same.
Those components are included on your MDM CD. Please ensure you use the same Version/support package/hotfix all over your landscape.
I hope that helps

Issue with Third Party Adapter for custom JCA Connector in Oracle 11g.

Hi,
For a proof of concept, I have created my own JCA Connector. I have deployed this connector in Weblogic and it works as expected.
Now I am trying to call the JCA Connecter from the SOA Bus. For this I have create a SCA Composite with a simple Web Service to expose the composite, a Third Party Adaptor to wrap the JCA Connector and a Mediator to wire the Web Service and the Third Party Adapter together. For the Third Party Adapter I have created both the needed *.wsdl and _3P.jca file my self. The problem is that I could not find any documentation about the _3P.jca file, and it looks like it that this file is new for 11g.
After some puzzling and debugging I am able to deploy the SCA Composite with the Third Party Adapter. Though when I test the exposed Web Service with the Enterprise Manager I get errors and a stack trace. The problem is that the Record Converter I have created receives the default XMLRecord implementation (oracle.tip.adapter.fw.record.XMLRecordImpl) and not the implementation of the XMLRecord I have created my self.
So the question is does anybody know how to configure the Third Party Adapter so that it will use my custom implemenation of the XMLRecord interface (oracle.tip.adapter.api.record.XMLRecord) instead of the default implementation of the XMLRecord (oracle.tip.adapter.fw.record.XMLRecordImpl).
I would suspect that it should be configured in the _3P.jca file, though I don't know how. The following is the content of the current _3P.jca file I am using.
<adapter-config name="DiskAdapter" adapter="Disk Adapter" wsdlLocation="JCADiskConnector.wsdl"
                xmlns="http://platform.integration.oracle/blocks/adapter/fw/metadata">
<record-converter className="com.osc.jcaadapter.convert.DiskRecordConverter"/>
<connection-factory location="jndi/diskcf" adapterRef=""/>
<endpoint-interaction operation="Send" portType="Send_ptt">
    <use-record-converter addonNamespace="http://somecomp.com/DiskAdapter"/>
    <interaction-spec className="com.osc.jcaadapter.impl.DiskInteractionSpecImpl">
      <property name="FunctionName" value="do-it"/>
    </interaction-spec>
</endpoint-interaction>
</adapter-config>So I am hoping that some one knows how you should configure the Third Party Adapter so it uses my own implementation of the XMLRecord interface.

Hi Simeon,
That is a good suggestion, and I would certainly try to do that if I was not making a proof of concept. It would solve my problem of not getting the sub class of the XMLRecord.
Though for making my proof of concept I found a 10g example that used sub classes of the XMLRecord, and that is why I wanted to get the same example to work on 11g.
The alternative of passing a parameter through with InteractionSpecs, is an interesting though can not solve this problem. I don't have a problem with the javax.resource.cci.Record, I can determine the implementation of that in the conversion class it self.
The problem is the XMLRecord generated by the Oracle SOA Adapter Framework, some how I need a way to influence that to generate the correct implementation of the XMLRecord.
So your post is certainly helpfull if I was not trying to get this specific problem to work :).
But I am afraid that I will end up in implementing your sugestion.
Regards
Maikel.

Does the JCA connector have a timeout mechanism

          Hi,
          does anybody know if JCA connectors has got a timeout mechanism in Weblogic 6.1?
          I don't support transactions in my JCA connector.
          My point of view is that there should be some one because
          if I do a call from the SessionBean and the connection of the
          EIS hangs, the ejb blocks.
          Thanks
          Andre


Hi Andre,
          in addition to add,
          Once you initiated the request/process, how much time to wait to get the
          result. If you are working with any EAI middleware vendors and developing
          adapters/connectors, then the timeout implementation and setting also be
          provided by them. so that you can directly use like below, the "execute"
          method in the implementation class of Interaction .
          This is a sample
          public boolean execute(InteractionSpec ispec, Record input, Record output)
          throws ResourceException
          //the below statement will do some process in the method "sendRequest",
          it may do some
          //repetitive process to get some values from your EIS and wait until
          the specified timeout
          //mentioned.
          m_connection.sendRequest(input, ispec.getExecutionTimeout());
          If you are not depends on any EAI vendor, Or if the API what you will use to
          connect EIS system and execute some thing and get result from EIS, if they
          are not providing a kind of waiting for some time to get result, then you
          may need to implement your own Timer Thread in the connector to wait for the
          specified timeout.
          Thanks

Need help to develop a custom connector

I need some help on developing the custom connector to Homegrown application and the version i am using is OIM9.0.3
First of all what are the steps do we need to care while developing a custom connector.
I can't able to find the process in google to develop the custom connector.
If you have any data regarding the development of custom connector, plz share to me....
What are the thing do we need to take care while developing the connector.
I referred in OIM9.1 version there was an option to develop the Custom connector by using Genric technology, can we create the custom connector by using the GTC feature in OIM 9.1
early response will be appreciated

The docs for the new GTC framework are here: http://download.oracle.com/docs/cd/E10391_01/doc.910/e10360/about.htm#Toc153968019. GTC is useful if you target application exposes standards-based SPML (Service Provisioning Markup Language) user management interfaces, although it sounds like this isn't the case for you.
You will most likely need to go the traditional route in terms of connector development, which involves building OIM Process Task Adapters to invoke the application API's (I assume they're Java?) and invoking those adapters from within an OIM Provisioning Process.

What is the recommended way of connecting to repository out of WebDAV, RMI, JNDI and JCA connector ?

What is the recommended way of connecting to repository out of WebDAV, RMI, JNDI, and JCA connector possibilities provided by CQ 5.5?

Hi dp_adusumalli,
I recognized your list of ~8 questions you posted at around the same time, as I received that same list in our customer implementation from Arif A., from the India team, visiting San Jose. :-)
I provided him feedback for most of the questions, so please check back with Arif for that info.
For this particular question, can you provide specifics for the types of interactions you are interested in?
Understanding the kinds of things you need to achieve will help determine which of the CQ/CRX interfaces is best suited for the task(s).
I've collated a few points on this subject on this page:

Using JCA Connector in Web AS Java 6.40 without EP6!?

Hi!
For my understanding the SAP Connector (JRA) offers a standard JCA 1.0 compliant connector to connect to R/3 using the CCI. So it should be usable in any J2EE server?
How can I use the JCA Connector in Web AS 6.40 (without EP)?
I found the sapjra.rar in J2E/SYS/global/ra/, but I cannot find how to configure a R/3 connection pool in Visual Administrator!?
How to configure the server and determine the JNDI lookup name for that resource to be able to look it up inside an EJB!?
With other J2EE containers, how to import the sapjra.jar and use it as standard JCA Connector?
Thanx for any help with this

Hi,
may be that Im a little bit to late, but for the next one who has the same problem the solution could be interesting.
You can change the default smpt port on Web AS Java in the server parameters of the java virtual maschine.
Open the SAP J2EE Config-Tool. Goto cluster-data | instance_<instance-id> | server_<server-id>. In the tab General insert unter Java parameters the line
-Dmail.smtp.port=<port> where <port> ist the port number of your smtp server.
Testet with SAP NetWeaver Portals / SAP NW 04s and SUN Java-VM but should also work with SAP NW 04.
Greetings

MQ Series JCA Connector run in Standalone OC4J but not in OAS on Linux

Hi all,
My problem is my application run in a Standalone OC4J in Windows and Linux and
in a Oracle Application Server 10.1.3 in Windows but not run in a Oracle
Application Server 10.1.3 on Linux why ?
When i try deploy my application in Oracle Application Server on linux the
error is throw:MQJMS2005: failed to create MQQueueManager for
'ms009.queue.manager'
In Standalone container in linux and windows and in a Oracle Application Server on Windows the deploy is fine.
I use the same configurations in all containers and only in a OAS 10.1.3 on
linux my app not run.
I thank any suggestions!

The JCA Connector to MQ Series run in Oracle Application Server on Linux ??
Standalone is OK i test but in OAS this run ??
The only difference entire OC4J configuration used in Standalone and OAS is in opmn.xml, that it is its necessary add a <enviroment> to found the MQ Libraries. Have another difference ??

JCA Connector: when is setLogWriter called by OC4J?

Does anybody know when OC4J calls the setLogWriter method of the ManagedConnectionFactory/ManagedConnection?
Thanks, Robert

And how to enable logging?
I know only the properties transaction.log, datasource.verbose, jdbc.debug, jdbc.connection.debug that can be set as system properties while starting OC4J (e.g. java -Ddatasource.verbose=true -jar oc4j.jar).
Are there more properties for turning on JCA Connector Adapter debugging/logging?
If yes, how can I set these properties for the OC4J embedded in JDeveloper?
Thanks,
Robert

Trying to develop a blocking method

This seems like it should be simple, but I've been trying to figure it out all morning. Basically, I want to develop a way to lock object across all instances to make it writeable. Creating a static boolean class variable will get me most of the way there, but I'm going for extra credit :) I want to have a method called "lock" that will ultimately guarantee an instance has exclusive write permission. If no instances currently hold the lock, it should simply set the boolean (I assume) and return. If another instance already has the lock, I want the lock method to block until it can get access to the lock. Ideally, this is queued so calls to lock are honored in the order they are received.
For example, I have two threads A and B. I have to ask you to use your imagination a little (since it is hard to demonstrate) and assume these blocks are overlapping on the respective threads.
//executing on thread A
LockableInstance a = new LockableInstance();
a.lock();
a.doSomething();
a.unlock();
//executing on thread B
LockableInstance b = new LockableInstance();
b.lock(); //thread A already holds a lock. this call waits until lock can be acquired.
b.doSomething();
b.unlock();The concept of blocking has really got me stumped. The one way I know this will work is to make lock() an infinite loop calling Thread.sleep until the class variable is unlocked. This seems inefficient for two reasons. For one, the sleep interval needs to be short, so it's just banging on the CPU (especially with many threads running). Another reason is that there is no guarantee locks will be obtained in the order they are requested.
Any ideas on how I could approach this?

I think I found what I needed :) For anyone interested, I can use an instance of java.util.concurrent.Semaphore. Specifically, I'm using a "binary" semaphore, which just an instance with 1allocated permit. Does exactly what I was trying to do!
New question... are semaphore objects hefty? If I have many classes using semaphores (one static instance per class), is it a drain on resources somehow? Is there something more efficient in binary cases?

Development of Cloud connector app

Hi,
I was just trying to build a simple cloud connector app but I am not finding exact document to start [ such as where we should write a program, which language, where to host etc]
If anyone can give me a step by step procedure, it would be of very great help.
Thanks,
Nikitha

HI Nikitha -
Cloud Connectors are an old framework, so I don't recommend you build on it. We have a new framework that allows you to extend the canvas in a much more powerful way with Actions, Decisions, Audiences and Menus (also Content for pages and emails). You can find the documentation here:
https://docs.oracle.com/cloud/latest/marketingcs_gs/OMCBA/index.html
for the specific questions you asked in the post: "where we should write a program, which language, and where to host" - the answer for all 3 is that it's up to you - we don't host the code for you, so you can feel free to choose your own hosting environment and whatever language are most comfortable with.

Developing Third Party Connectors for the Universal Worklist

Hi,
We need to develop a third party connector for the Universal worklist.
In order to retrieve the workflow items we want to use a web service that will be developed according our needs.
The documentation that I found regarding the UWL states that in terms of connectivity we can use Web based protocols such as HTTP and Web Services, but i couldn't find any example for this, besides the SONIC.
Has someone already developed a third party connector? Examples?
Thanks in advance.
Best regards,
José

Problems trying to develop a template using Fluid Grid Design

Having serious problems trying to get a template to work using Fluid Grid Design with Dreamweaver CS6
I have develop my template with editable regions etc, however when I load it to make an html5 page and preview it on any browser it comes completely blank
If I do this on an HTML5 document without Fluid Grid it comes out fine.
I heard this issue is happening to other people as well
Need to resolve this issue as soon as possible
Your help will be highly appreciated
Mike Riego

Before you create a template, you need to a) properly define a local site folder in DW. And b) test your prototype (Fluid Grid page) to ensure the code is valid and it works in all target browsers/devices.
When you're completely happy with your prototype page, SaveAs a DW Template and close it.
DW will create a Templates folder in your local site folder for you.
1. File > New > Page from Template > select your newly created template from the 3rd panel. Hit Create.
2. This is a child page spawned from a Template.dwt.
SaveAs index.html.
Preview in browsers. It should work just fine.
Repeat Steps 1-2 for remaining site pages.
