Java EE (Java Enterprise Edition) General Discussion

Hi all


I am working on some RFID-related project. I need to capture, fiter and then perform some other tasks on the data sensed by RFID readers, all in Java. So I choose Sun's software. There was no luck when I was trying to configure my system to work with Sun's software. Hope you experienced could do me a favor and help me out. Thanks in advance. Here are details.

In the installation guide of Sun Java System RFID Software 3.0, it says, to install RFID information server, Sun Java System Application Server Platform Edition 8.1 2005Q2 UR2 and PostgreSQL 8.0.4 are needed.

For the following 2 reasons:
1 PostgreSQL 8.0.4 is now not available to download on www.postgresql.org;
2 I think later version of PostgreSQL or Sun Application Server should be compatible to their earlier versions
I tried the following combination other than those stated in the installation guide:
1 PostgreSQL 8.3;
2 Sun Java System Application Server 9.1_02, bound with Sun Java Application Platform SDK Update 5;
3 Sun Java System RFID Software 3.0

Then, the application server successfully communicates with PostgreSQL, demonstrated by "ping success" through the connection pool built in application server's admin console.
The RFID information server communicates successfully with PostgreSQL, demonstrated by deploying RFID information server database successfully in PostgreSQL.
But, instructed by the installation guide, when I tried to validate my RFID information server installation by typing "http://localhost:8080/epcis" in the browser, the application server reported "the resource is not available".

I looked into many other internet resources and instructions about this, but no luck at all. I am now really, really stuck. Hope you could do me this favor. Thanks.

PS:

1 PostgreSQL8.3 is available on http://www.postgresql.org/download/
2 Sun Java System Application Server is available on http://java.sun.com/javaee/downloads/index.jsp
3 Sun Java System RFID Software and the installation guide are available on https://sun-rfid.dev.java.net/SJS_RFID_Software.html
4 Operation System is Windows XP
