Need to access initialized BDM variables in Bonita 7.3.0 BPM from my java code using Engine API.

Following is the code that I have implemented:

loginAPI = TenantAPIAccessor.getLoginAPI(); session = loginAPI.login("walter.bates", "bpm"); processAPI = TenantAPIAccessor.getProcessAPI(session); List processes = processAPI.getProcessInstances(0, 20, ProcessInstanceCriterion.STATE_ASC); for(ProcessInstance p : processes) { if(p.getName().equalsIgnoreCase("My Task")) { processId = p.getId(); } } Map context = processAPI.getProcessInstanceExecutionContext(processId); SimpleBusinessDataReferenceImpl procOrderStorageId = (SimpleBusinessDataReferenceImpl) context.get("procedureOrderMaster_ref"); //procedureOrderMaster is a BDM variable created in bonita BusinessObjectDAOFactory daoFactory = new BusinessObjectDAOFactory(); MasterProcedureOrderDAO procedureOrderDao = daoFactory.createDAO(session, MasterProcedureOrderDAO.class); MasterProcedureOrder procedureOrder = procedureOrderDao.findByPersistenceId(procOrderStorageId.getStorageId()); System.out.println("Procedure Order Id: "+procedureOrder.getProcId()+" Status: "+procedureOrder.getStatus());

Also added bonita-client-pojo.jar file.

Encountering ClassNotFoundException :

As this is an external program rather than an internal Connector I suspect you have to include the necessary class file into your programs build directory.

A Tip on displaying CODE/LOGS correctly in Posts:

Do not use the Supplied Buttons above, for some reason they refuse to work correctly, and despite bringing it to Bonitasofts attention, it’s low priority.

To Show Code/Logs correctly use

< code >
your code/log
< /code >

removing the spaces to allow the showing of code/logs correctly as here:

your code/log

You should still be able to edit your post to ensure the correct formatting of the code to help us understand it easier.

Thanks and regards
