Sai,
The service task properties are declared in this way :
| Interface | org.jbpm.biomorf.sample.demo.EvenOddNumberCheckServiceImpl |
| MetaData | {height=53, width=99, UniqueId=_9-3, y=121, x=129} |
| On Entry Actions | [System.out.println(" entering into service task ");] |
| On Exit Actions | [System.out.println("exiting service task");] |
| Parameter Mapping | {Parameter=inputNumber} |
| ParameterType | java.lang.String |
| Result Mapping | {Result=inputNumber} |
Can anyone please see the below error and let us know what to do...
We are not able to run the service task inside an Adhoc-sub-Process. When run the task, I get the following error :
