I can't use the NB Debugger(f5):
init:
deps-module-jar:
deps-ear-jar:
deps-jar:
library-inclusion-in-archive:
library-inclusion-in-manifest:
compile:
compile-jsps:
do-dist:
dist:
debug:
Incrementally deploying http://localhost:8084/WebApplication4
Completed incremental distribution of http://localhost:8084/WebApplication4
Duplicated project name in import. Project WebApplication4-impl defined first in
C:\Documents and Settings\Jaime
Fernandez\WebApplication4\nbproject\ant-deploy.xml and again in C:\Documents and
Settings\Jaime Fernandez\WebApplication4\nbproject\build-impl.xml
connect-debugger:
Non-existing path "C:\Documents and Settings\Jaime
Fernandez\WebApplication4\build\ear-module\WEB-INF\classes" provided.
C:\Documents and Settings\Jaime
Fernandez\WebApplication4\nbproject\build-impl.xml:560: The following error
occurred while executing this line:
C:\Documents and Settings\Jaime
Fernandez\WebApplication4\nbproject\build-impl.xml:564:
org.netbeans.api.debugger.jpda.DebuggerStartException
BUILD FAILED (total time: 2 seconds)

The "Duplicated project name in import" error i can solve putting name project
in the ant archive, but second i can't.
Then i try to use Attach debugger:
Debugger Console:

Attaching to PCNAME:11555
