Human Task Java API

Question

Hi
I have a requirement to create human tasks without using soa. I am trying to use the Human task Java API. Using this API I can do all the operations like updating the outcome, adding/updating comments and updating assignee list but not able to create initial task. I am using initiateTask operation which requires task definition id. I dont know how to set this. Can anybody guide me
1. Can I create human tasks without using composite pure java api?
2. If I am able to create initial task what will be the task definition id? I tried to enter a new row in soa infra meta data table which did not work.
I really appreciate the help.
Thanks

Hi Sri
I have few Processes deployed to my SOA Domain and that too under different Partitions. For ease of maintenance, in EM Console under soa_infra node instead of default partition we can have our own Partitions also to deploy specific workflow projects under those partitions. If you don't have this thats ok.
I looked at Payload data for all the Tasks submitted by the first Initiator Task in EM Console, when we check the Flow Trace etc. Here is what I found for <taskDefinitionId> value for each of my different Processes. They do have some Pattern. So you had to use some sort of properties file to get these values so that if they are deployed to different partitions and with different versions, you do not have to modify your java code and recompile it. Just modify .properties file.
Anyhow, looks like the format for <taskDefinitionId> is something like this:
NameOfPartition + "/" + NameOfProcess + "!" + VersionNumber + "/" + NameOfInitiatorHumanTask
Here are some examples from my domain for some of the Process.
<taskDefinitionId>default/SalesQuoteProcess!1.0/EnterQuote</taskDefinitionId>
<taskDefinitionId>Ravi1_Partition/CreditReviewRequestProcess!1.0/HumanTaskCreditRequestor1</taskDefinitionId>
<taskDefinitionId>Jegga1_Partition/HolidayProcess!1.0/StartNewHolidayTask</taskDefinitionId>
You already tried hardcoding it I guess and it worked. Now try generating them dynamically using simple String appenders and sort of properties file to make it more dynamic. How often do we really change partition name or human task name itself or name of process itself. They are pretty much fixed. Now comes only the Version number. This can change with your new deployment if you want to have different version. So just read all these from .properties file.
