答复: RE: 答复: Re: How to create process

Hi,

  Thank you for your help,I have resolved the problem using your method.

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.

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");

          }

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.
