Java Development Tools

I have been able to debug locally when I start debug from IntegratedWebLogicServer,
but I have not been able to debug remotelly although I deploied successfully to WebLogic Server and I got correct result while testing from SoapUI.
With the purpose to debug remotelly the simple web service described below, I have done these steps on my enviroment:

On WebLogic
1) In the WebLogic console, belong the AdminServer definition, I browsed to Protocol > HTTP Tunneling and I checked it.

2) In startWebLogic.cmd I added:
set JAVA_OPTIONS=-Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,address=4000,server=y,suspend=n %SAVE_JAVA_OPTIONS%

3) In setDomainEnv.cmd I changed to be:
set debugFlag=true
...
if "%debugFlag%"=="true" (
set JAVA_DEBUG=-Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,address=%DEBUG_PORT%,server=y,suspend=n -Djava.compiler=NONE
set JAVA_OPTIONS=%JAVA_OPTIONS% %enableHotswapFlag% -ea -da:com.bea... -da:javelin... -da:weblogic... -ea:com.bea.wli... -ea:com.bea.broker... -ea:com.bea.sbconsole...
)
After that, I restarted the weblogic.

On JDeveloper
4) In the page Project Properties > Run/Debug/Profile > Default > Edit:
I wrote the path to the HelloWorld.java on Default Run Target box.
I checked Remote Debugging

5) I right clicked the project and clicked Start Remote Debugger.
On Attach to JDPA Debugger window I wrote LocalHost on Host and 4000 on Port.
In my log window I got this message:
"Debugger attempting to connect to remote process at LocalHost 4000.
...Debugger unable to connect to remote process."

I was expecting to be able to call the web service from SoapUI and then stop on my breakpopint. What else should I do?

The only suggestion found on internet I have not done was
"In order for JDeveloper to work with WebLogic it will need a copy of the weblogic.jar file that can be found at [WLS-root]\weblogic1001\server\lib, copy this file to [jdev-root]\jdev\lib\ext directory and restart JDeveloper."
(http://www.oracle.com/technetwork/developer-tools/jdev/remotedebugwls-086628.html) I didn't find the path [jdev-root]\jdev\lib\ext in my computer.
