Re: JCA - connection to legacy system network sockets etc

[Duncan Alexander]

The example connector adheres to the standard Connector architecture so it should be deployable on any app. server which supports JCA. Also it uses a cloudscape connection underneath so you will need the driver and an eval copy of Clouscape to get it working. It comes packaged as a .rar file with an ra.xml deployment descriptor and a weblogic specific weblogic-ra.xml descriptor. For other servers you will need to swap out the weblogic-ra.xml for the relevant named file. As far as JBoss goes it includes JBossCX which allows JCA connectivity so you should be OK there.   > After I have read data from it, it can send me a message saying that it has changed > the data that I have read ....   Unless Im mistaken by what your saying it seems you may need the support of Asynchronous communication which will be available in JCA 2.0.  But in the meantime cant you use Message Driven Beans in conjunction with an adapter for your legacy system to listen for messages about data changes.   regards   DGA       -----Original Message----- From: A mailing list for Enterprise JavaBeans development [mailto:[EMAIL PROTECTED]] On Behalf Of David Cassidy Sent: 15 March 2002 17:02 To: [EMAIL PROTECTED] Subject: Re: [EJB-INT] JCA - connection to legacy system network sockets etc   Duncan Alexander wrote: Has anyone created a JCA (Java Connector java.sun.com/j2ee/connector) for connection to a legacy system. There is an example Connector which comes with Weblogic 6.1....it may give you some pointers if your going to write your own. You can get hold of it if you download the eval copy of Weblogic. Excellent, Thanks ! Will it work with say JBoss ? The only gotcha as far as I can see is that the old system will send us data back up the connection that will change our data. Do you mean that you cannot read from your legacy system without changing the state of the data within it? No, After I have read data from it, it can send me a message saying that it has changed the data that I have read ....

I need to create one to talk to one of our old systems. The only gotcha as far as I can see is that the old system will send us data back up the connection that will change our data. Anyone got any experience ? Any hints ?
