Hi zhang

> deploymentId = repositoryService.createDeployment()

I am not sure what exactly you mean be "update the table"
* "updater the content of a table" (update) is perfectly normal in this case since this statement is supposed to put a workflow definition into the database
* "update the structure of a database table" (alter table) shouldn't happen here, are you seeing this?

> Oracle error still took place.
can you show us the stacktrace please?

> Another question, I run the examples on hsqldb-server. The statement below:*ProcessInstance processInstance = executionService.startProcessInstanceByKey("Java", variables);*
> ** 
this should start a workflow with the name "Java" if you previously deployed such a workflow

> ** 
> I could *not find out how the  processInstance executed by key "java".*

> I wrote a console with the same statement. Came out an exception "no instance with key named 'java'".
make sure you deployed a workflow with the name "java", or is it "Java"?
