ADF: Query-By-Example table filter bug

Status: open
Applies to JDeveloper:,

Today I tried if the Bug (discussed in is still reproducible.
And sadly to say: “Yes the bug still exists!”
The behaviour changed a bit but the table filtering feature still does not working as expected if used INSIDE PAGE FRAGMENT/TASKFLOW.
So take a look at the viewlet where I shortly explain the buggy behaviour.

TELDE - What's that?

If you are wondering what telde is all about then I would like to give a hint on a presentation my collegue Ulrich gave at DOAG 2009 : ADF 11g rich client development best practices . We are using TELDE for development, testing and so on...while developing Apps on the oracle stack (currently ADF11g/JDeveleloper/WebLogic/Oracle Enterprise Linux). So TELDE stands for

TEam Linux Development Environment

It consists of the following components right now:

Oracle Enterprise Linux 5.3

Oracle Database

Oracle WebLogic Server 11g

Oracle JDeveloper 11.1.1.x

Oracle Team Productivity Center

Hudson Continuous Integration Server 


SVN Server

running on VMWare.

So if you are interested in setting up such an environment, look at

Status: resolved
JRockit Mission Control: 3.1.2
WebLogic: 10.3.2

Use case

You have the need to remotely monitor and profile the JRockit JVM(s) of Oracle WebLogic Server.


  1. Install JRockit Mission Control on the client
  2. Configure WebLogic Server Domain with JRockit JVM
  3. Configure JRockit Management Server


 Oracle® WebLogic Server
Download from OTN
 Oracle® JRockit Mission Control 
Download from OTN 

How to

Login as oracle
on telde.local
[oracle@telde ~]$ cd middleware/user_projects/domains/base_domain/ [oracle@telde base_domain]$ vi
Putty/viAdd the following java Options before starting the WLS instance:


${DOMAIN_HOME}/bin/ $*

Save file and Close vi.
PuttyStart WLS

[oracle@telde base_domain]$ ./
Notice the starting of the management server

[JRockit] Management server started on port 7091, ssl=false, authenticate=false.

ClientStart JRockit Mission Control
JRMCCreate a new connection
Enter Host
Enter Port
Click: Test connection
=> Status keeps “Unable to connect”
Click: Finish

Starting the console on the newly created connection you might receive the following exception:

Could not open Management Console for telde.local. Connection refused to host:; nested exception is: Connection refused: connect Connection refused to host:; nested exception is: Connection refused: connect

So how to fix?

PuttyStop WLS
Add -Djava.rmi.server.hostname=<remotehost> to the java options so that it looks like


JAVA_OPTIONS="-Djava.rmi.server.hostname=telde.local -Xmanagement:ssl=false,authenticate=false,port=7091"

${DOMAIN_HOME}/bin/ $*

Save file and exit vi.

PuttyStart WLS once again

[oracle@telde base_domain]$ ./
JRMCNow try to test connection again.
Result should be
JRMCStart the console and monitor CPU, Mem, seak for memory leaks, etc.


java.rmi.server.hostname (1.1 and later)

The value of this property represents the host name string that should be associated with remote stubs for locally created remote objects, in order to allow clients to invoke methods on the remote object. In 1.1.7 and later, the default value of this property is the IP address of the local host, in "dotted-quad" format.
