[Design of JBoss jBPM] - Re: jbpm-api first draft

by tom.baeyens＠jboss.com

i would like to see how in this proposal we're going to implement cross cutting concerns like authorization, transactions, retry upon optimistic locking failure and make it configurable for different environments like plain java, servlet, ee, seam, spring,... not all the details are necessary, just the interception points. as far as i got it, your proposal seems to reflect the pattern of a statefull session bean, while i can only see it work with a stateless session bean approach.

[Design of JBoss jBPM] - jBPM3 API now based on microcontainer

Folks, the API now gets its artifacts configured through the MC | <deployment xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="urn:jboss:bean-deployer:2.0 bean-deployer_2_0.xsd" | xmlns="urn:jboss:bean-deployer:2.0"> | |  | <bean name="jBPMProcessEngine" class="org.jbpm.integration.client.ProcessEngineImpl"> | <property name="processDefinitionManager"><inject bean="jBPMProcessDefinitionManager"/></property> | <property name="processInstanceManager"><inject bean="jBPMProcessInstanceManager"/></property> | <property name="executionManager"><inject bean="jBPMExecutionManager"/></property> | </bean> | |  | <bean name="jBPMProcessDefinitionManager" class="org.jbpm.integration.client.ProcessDefinitionManagerImpl"> |  | </bean> | |  | <bean name="jBPMProcessInstanceManager" class="org.jbpm.integration.client.ProcessInstanceManagerImpl"> |  | </bean> | |  | <bean name="jBPMExecutionManager" class="org.jbpm.integration.client.ExecutionManagerImpl"> |  | </bean> | | </deployment> | With this abstraction in place it should be possible to implement the mapping for the JBPM4 code base You can consume the API and the related tests from cheers http://snapshots.jboss.org/maven2/org/jboss/jbpm/ View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4159503#4159503 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4159503

"heiko.braun(a)jboss.com" wrote : I am wondering why the schema contains element declarations for concrete activities like 'email'. IMO we shouldn't treat the stock activities anyhow different as the ones user supply. That means they wouldn't be represented by an element name on it's own. jPDL is an executable process language. Each node is of a certain type. One node type will delegate to an activity implementation (== direct mapping to the PVM construct). Another node type will call a java method through running a script or evaluating an expression. Other node types do more functional behaviour like email. Separating the structure from the activity behaviour would make the XML a lot more verbose and hence less readable. "heiko.braun(a)jboss.com" wrote : On the other hand, if we move stock activities to a custom namespace, then they are separated from the core xsd constructs. using separate namespaces for user defined node types is certainly something that i think should be possible. but a whole process should be usable without namespaces as well, i think. just referencing the core jpdl xsd in the default namespace is simple. so that should never be a problem. but combining namespaces is what always should be optional. meaning. the functionality should always be available with or without setting up the namespaces properly. so when users want to add a new node type, i don't want them to be forced to write an xsd and configure the namespace in the process.

On the other hand, if we move stock activities to a custom namespace, then they are separated from the core xsd constructs. Maybe we should allow user to introduce the0ir own namespaces? Let say you provide an XSD with custom activities for inclusion and your activities derive from a base type, then people could do do something like: | <process-definition> | <xmlns="http://foo.bar.com/order/v1" creditcardVerification/> | </process-definition> | Whereas creditcardVerfification derives from http://jbpm.org/jpdl-4:activity.
