Hi, in our projects we use the HttpInvoker component of Spring to interact with our remote KnowledgeBase through HTTP, which means JBPM5 is deployed in a servlet container. Our Websphere admin is afraid that JBPM5 creates its own threads instead of using the thread provided by the container. In short: - Does JBPM5 always executes in the thread of the caller ? - What is the purpose of the 'multithread' element in drools-spring.xsd (drools-spring-5.2.0.M1.jar) ? I cannot find answers in the documentation :-( Also, it would be a good idea to document the XSD like Spring does with <xsd:documentation /> tags.
