Uima AS not allowing deployment of more than one deployment descriptor in the
same jvm
--------------------------------------------------------------------------------------
Key: UIMA-1405
URL: https://issues.apache.org/jira/browse/UIMA-1405
Project: UIMA
Issue Type: Bug
Components: Async Scaleout
Reporter: Jerry Cwiklik
Priority: Minor
Uima AS fails with ResourceInitializationException when one tries to deploy
more than one deployment descriptor using deployAsyncService script. The
problem is that components in generated spring context files are deployed into
a single Spring container. But each spring context files defines singleton
objects that are not meant to be used externally. An example of such non-shared
singleton would the InProcessCache. It is meant to be shared by components
defined in a single context file. There are few possibly solutions here:
1) modify dd2spring to assign unique names to spring beans to prevent sharing
across context files.
2) modify uima-as deployer to deploy each context file in a separate spring
container
3) find a way to prevent spring from sharing singleton objects across context
files.
