Hello Skysea,

Frankly, I am not sure I understood the question (what you mean by "save it to
the database"). But I'll try to explain you what I do and it may be helpful.

I have put in place workflow for the web content publishing. Since workflow is
nothing more than consumer of user actions, I needed persistence of the
association of the web content with the process in order to be able to, first,
infinitely in time extend access to the process instance, and second, be able
to communicate the process instance between different application instances.

For that I have created my own database, added a simple table with just two
fields, processInstanceId and webContentId. Now whevever I need to figure out
the state of my web content ID, I query the table, see if I have a process
accociated with it and then query the Shark for the rest.

If this is kind of persistence you are looking for then here it is - trivial
and effective.

DS

Hello,DS:

I am glad to receive your message,your understanding is right.when I created a process in my program,how can I persist it?Do you give me a example?

This is my codes for creating process:

public static void createInstance(String username, String pwd,String pkgID) throws Exception

{

SharkInterfaceWrapper.setProperties("D:\\tws-community-2.4-8-25\\conf\\Shark.conf", true);

UserTransaction ut = (UserTransaction) new InitialContext().lookup("java:comp/UserTransaction");

ut.begin();

SharkConnection sc = SharkInterfaceWrapper.getSharkConnection("admin", null);

WMConnectInfo wmci=new WMConnectInfo("admin", "12", "Shark", "");

sc.connect(wmci);

String pkgId = "sqpkg#1#sqpkg_wp1";

String pDefId = "0";

String procDefName = SharkInterfaceWrapper.getShark()

.getXPDLBrowser()

.getUniqueProcessDefinitionName(sc.getSessionHandle(), pkgId, "", pDefId);

WfProcessMgr mgr = sc.getProcessMgr(procDefName);

WfProcess process = mgr.create_process(null);

process.start();

System.out.println("success");

}

Well, it looks like you need to read some docs. Apparently you were able to
find some info how to create process. So if you keep reading further, you'll
find very nice example of how to search for processes, activities, etc. process
has key() method. That's what you persist and what you use in the filter to
recreate process object later. Again just check out the docs directory.

Winstone,

Try putting ut.commit(); at the end of the procedure to commit your changes to the database.

You need to look for documentation on JTA rather than Shark.
