Which ReferenceService configuration are you using? If you are using InMemory
you should try the Hibernate configuration.
I have no idea how to switch between the two configurations and which
effect they have. A short explanation would be helpful.
I am using the "general" approach from the tutorial:
InvocationContext context = callback.getContext();
ReferenceService referenceService = context.getReferenceService();
T2Reference containerRef = referenceService.register(data, 1, true,
context);
outputs.put(port, containerRef);
What's the difference whether I deliver the old context object or null.

I have used JProfiler to profile the memory usage in the Taverna engine - it
seemed to work quite well.
I will give it a try.
The latest snapshot of Taverna 2.3 has much improved memory usage - it may be
worth trying that version.
Am I right that I have to change
<properties>
<t2.core.version>1.1</t2.core.version>
<t2.activities.version>1.1</t2.activities.version>
<t2.ui.api.version>1.1</t2.ui.api.version>
<t2.workbench.version>2.1.2</t2.workbench.version>
</properties>
to
<properties>
<t2.core.version>1.1</t2.core.version>
<t2.activities.version>1.1</t2.activities.version>
<t2.ui.api.version>1.1</t2.ui.api.version>
<t2.workbench.version>2.3</t2.workbench.version> <----
</properties>
Are there also new versions available for the other parts?
So many questions so little time :)
