Method Detail

createDeploymentLockObjectOnDeploy

public void createDeploymentLockObjectOnDeploy(@Observes
                                               org.jbpm.kie.services.impl.event.DeploymentEvent event)

Adds a deployment lock object.

Parameters:

event - The DeploymentEvent fired on deployment

cleanUpOnUndeploy

public void cleanUpOnUndeploy(@Observes
                              org.jbpm.kie.services.impl.event.DeploymentEvent event)

Remove the cached JAXBContext and deployment lock object

It's VERY important that the cached JAXBContext instance be removed! The new deployment may contain a different version of a class with the same name. Keeping the old class definition will cause problems!

Parameters:

event - The DeploymentEvent fired on an undeploy of a deployment

getJaxbContext

public JAXBContext getJaxbContext(Class<?> type,
                                  javax.ws.rs.core.UriInfo uriInfo)

This method does the following:

1. Determine the deployment id from the UriInfo instance.
2. If the deployment id can not be determined, return a default JAXBContext instance.
3. If a JAXBContext instance has already been created for this deployment, retrieve it from the JAXBContext cache (contextsCache) and return it.
4. Create a JAXBContext instance based on the classes from the appropriate deployment.
5. Cache the JAXBContext instance and return it.

Parameters:

type - The Class of the new object that should be deserialized by returned JAXBContext.

uriInfo - A UriInfo instance needed to determine the deployment containing the necessary classes.

Returns:

A JAXBContext instance
