Found that Hello-JAXWS sample project can Run successfully many times if we
don't undeploy it (web application) from the RunTime/Servers/domain1.

If we undeploy this application from IDE, it cannot run any more.

How to produce:
verify ${javee.home}/domains/domain1/autodepoly does not have sub directories 
for this webservice

*** launch IDE & start the domain1 server (local default domain)
1) open project and select the folder for Hello-jaxw sample

2) select Run Project

3) wait a little bit, refresh/expand the already added server
domain1/applications and see in Web Applications an entry for
the endpoint_Hello expand and find 3 entries jsp/default and Hello.

4) look in the View the Server log message:

[AutoDeploy] Selecting file
/opt/SDK/domains/domain1/autodeploy/endpoint/Hello.class for autodeployment.
wsgen successful

5) In the Ouput Hello-jaxw:

Hello result = Hello root!
run-client:
BUILD SUCCESSFUL (total time: 1 minute 8 seconds)

6) run the project many times, with no problem.

7) clean Project/ Run Project with no problem appclient is still ok, clean and
build Project is Ok.

8) View Admin Console, and can see in Server log:

ISSUE 2 (may be related to ISSUE1):
<<
com.sun.enterprise.admin.mbeans.J2EEModule:getStringForDDxml
FileNotFoundException
/opt/SDK/domains/domain1/generated/xml/j2ee-modules/endpoint_Hello/null
>>

But within the console I can see a Hello entry in WebServices and was able to
test it (using Test button),
but I could not find a WebServices/Hello entry in IDE.
I think I've seen a  WebServices entry (empty) after a fresh install of the SDK
in domain1 but don't know why is not generated anymore.

9) undeploy the web application endpoint_Hello and this will break the Run of
the project.

will get the error at get-artifacts-unix/windows 
parsing WSDL

[ERROR] Failed to read the WSDL document:
http://localhost:8080/Hello/HelloService?WSDL, because 1) could not find the
document; /2) the document could not be read; 3) the root element of the
