UWL Item URL Links

Question

Hello Experts,
I have created a Webdynpro application in which i have the UWK Items. I am able to read all the properties of the items.
But I don't know how to create the URL for the specific ITEMS,  to open the item, when clicked.
Can you please provide me information of how to create the specific Item URLs, which i can link to the Item.
Regards,

Hi,
Try the following
package samplepackage;
import java.util.Iterator;
import java.util.Locale;
import java.util.Properties;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import com.sap.netweaver.bc.uwl.IUWLItemManager;
import com.sap.netweaver.bc.uwl.IUWLService;
import com.sap.netweaver.bc.uwl.IUWLSession;
import com.sap.netweaver.bc.uwl.Item;
import com.sap.netweaver.bc.uwl.ItemCollection;
import com.sap.netweaver.bc.uwl.QueryResult;
import com.sap.netweaver.bc.uwl.UWLContext;
import com.sap.netweaver.bc.uwl.UWLException;
import com.sap.security.api.IUser;
import com.sap.security.api.UMFactory;
public class Sample {
  public void retriveItems() {
    try {
      // look up UWL service
      IUWLService uwlService = findService();
      // define session timeout perios
      final int sessionIdleTimeout = 60;
      // create context
      UWLContext uwlContext = new UWLContext();
      // find logged in user.
      IUser user = //TODO Get the user for whom the items are to be retrieved.
      uwlContext.setUser(user);
      uwlContext.setLocale(Locale.getDefault());
      // begin session
      IUWLSession uwlSession;
      uwlSession = uwlService.beginSession(uwlContext, sessionIdleTimeout);
      uwlContext.setSession(uwlSession);
      IUWLItemManager itemManager = uwlService.getItemManager(uwlContext);
      QueryResult result = itemManager.getItems(uwlContext, null, null);
      ItemCollection items = result.getItems();
      Item item = null;
      for (int i = 0; i < items.size(); i++) {
        item = items.get(i);
        Map params = new HashMap();
        params.put("taskId", item.getExternalId());
        String executionURL = WDURLGenerator.getApplicationURL("sap.com/tcbpemwdui~taskinstance", "ATaskExecution", params);
        //TODO Add code send mail which contains above URL.
    } catch (UWLException e) {
      e.printStackTrace();
    } catch (NamingException e) {
      e.printStackTrace();
  // look up UWL service
  private IUWLService findService() throws NamingException {
    Properties env = new Properties();
    env.put(InitialContext.INITIAL_CONTEXT_FACTORY, "com.sapportals.portal.prt.registry.PortalRegistryFactory");
    // create initial context
    InitialContext ctx = new InitialContext(env);
    // retrieve UWL service
    IUWLService uwlService = (IUWLService) ctx.lookup("/broker/services/" + IUWLService.ALIAS_KEY);
    return uwlService;
