This chapter provides an overview of Department API and describes the use cases using this API.
This chapter contains the following sections:
Departments can be created, read, queried for, and modified. These operations are described below. Bear in mind that once a Department is created, it cannot be deleted. Only two Department attributes are meaningful to a user: name and description.

Description
The following sample code illustrates typical tasks involving the manipulation of departments in Oracle Enterprise Repository. This includes creation, updating, querying, and deleting.
Sample code is as follows:
package com.flashline.sample.departmentapi; import java.net.MalformedURLException; import java.net.URL; import java.rmi.RemoteException; import java.util.Calendar; import javax.xml.rpc.ServiceException; import com.flashline.registry.openapi.base.OpenAPIException; import com.flashline.registry.openapi.entity.AuthToken; import com.flashline.registry.openapi.entity.Department; import com.flashline.registry.openapi.query.DepartmentCriteria; import com.flashline.registry.openapi.service.v300.FlashlineRegistry; import com.flashline.registry.openapi.service.v300.FlashlineRegistryServiceLocator; public class Departments { public static void main(String pArgs[]) throws java.rmi.RemoteException, OpenAPIException { try { /////////////////////////////////////////////////////////// // Connect to Oracle Enterprise Repository /////////////////////////////////////////////////////////// URL lURL = null; lURL = new URL(pArgs[0]); FlashlineRegistry repository = new FlashlineRegistryServiceLocator() .getFlashlineRegistry(lURL); // ////////////////////////////// // Authenticate with OER // ////////////////////////////// AuthToken authToken = repository.authTokenCreate(pArgs[1], pArgs[2]); // ////////////////////////////// // Create a new department // Each Department requires a unique name.

A SearchTerm // is a key/value pair. Currently the only valid key is "name". // // A query for name is a match if the value for the name term // occurs anywhere in the name of the department. For example, // a search for fred matches fred, alfred, and fredrick. // ////////////////////////////// DepartmentCriteria criteria = new DepartmentCriteria(); criteria.setNameCriteria("DepartmentName"); Department[] depts = repository.departmentQuery(authToken, criteria); // ////////////////////////////// // Update a department // // To update a Department you need only to modify a Department // reference and call departmentUpdate... // ////////////////////////////// String lOldName = dept.getName(); String lNewName = "New " + dept.getName(); Department dept3 = repository.departmentRead(authToken, lOldName); dept3.setName(lNewName); repository.departmentUpdate(authToken, dept3); } catch (OpenAPIException lEx) { System.out.println("ServerCode = " + lEx.getServerErrorCode()); System.out.println("Message = " + lEx.getMessage()); System.out.println("StackTrace:"); lEx.printStackTrace(); } catch (RemoteException lEx) { lEx.printStackTrace(); } catch (ServiceException lEx) { lEx.printStackTrace(); } catch (MalformedURLException lEx) { lEx.printStackTrace(); } } }
