Hello,

another task running from the the inbuilt script.But how shall I stop the other task.I can
view the result in Console but I cannot go through the processes tab.I hope I will find
the solution soon.
Thanks in Advance

I have removed the human task from the build.xm and now its not showing the error with the
port 9123, But now I have some other problems, so I am not sure from where the problem
begins I cannot export my package to the guvnor frontend fromt the eclipse side and I also
cannot view the process in the jbpm console.I am not sure which code you are talking about
but I am attaching my java code, bpmn2.0 and the .ftll files and all the configuration
files as well, so that you can have a look.
Thanks

Hello Vishal,
You have to set the package name of the process, and that package name should be the same
as in guvnor.
You have to set the package name in properties (try clicking on the white space of the
eclipse process canvas) as defaultPackage.
Unfortunately JBPM console uses hardcoded *packageName* string when getting processes from
guvnor. Therefore you have to put your process, freemarker forms and png image into
defaultPackage.(also make sure that your process declares *defaultPackage* as its
package).
Please check your process contains the name of the package.
<process processType="Private" isExecutable="true"
id="AuthorizationProcessSGG" name="Authorization_Process_SGG"
*tns:packageName="defaultPackage"* >
At the end your jbpm console should now list your process as well.
Greetings .-
alexis_lalas

But I cannot import or export anything from the Eclipse to the guvnor. I have tried to
upload my ftl, bpmn and image file through but I cannot see the option to add to guvnor
existing repository, as it is highlighted.I hope it will make you to understand the
situation.
Greetings
Vishal
