How to Start/Launch another WD application using a link.

Question

Hi, I've been trying to see if there's an official way that I can launch another WD application using a link from within an application where the applications are not in the same deployable object.
P.S.  I've seen the other thread of how to do it when the applications are within the same deployable object.
Thanks in advance as always,

Hi Michael,
of course it does, so the question should be:
"Hey, how do it get the application URL of a WD application without hardcoding the server name, port or whatever?"
This is simple:
   * Return is the application URL for the specified <code>deployableObjectPart</code> with appended 
   * URL parameters given by <code>urlParameters</code>. All key/value pairs in the map must
   * be of type java.lang.String.
   * @param deployableObjectPart a deployable object part representing a Web Dynpro application
   * @param urlParameters key/value pairs added as URL parameters; they must be of type String
   * @return the application URL for the specified <code>deployableObjectPart</code> with appended 
   * URL parameters given by <code>urlParameters</code>
   * @throws WDURLException if the URL couldn't be generated
   * @see com.sap.tc.webdynpro.services.sal.url.api.WDURLGenerator#getApplicationURL(WDDeployableObjectPart)
  public static String getApplicationURL(WDDeployableObjectPart deployableObjectPart, Map urlParameters) throws WDURLException {
    return AbstractManager
      .getServerPlatformImplementation()
      .getURLGeneratorFactory()
      .getURLGenerator()
      .getApplicationURL(deployableObjectPart, urlParameters);      
or if you would like to get it load balanced:
   * Return is the workload balanced application URL for the specified <code>deployableObjectPart</code> with appended 
   * URL parameters given by <code>urlParameters</code>. All key/value pairs in the map must
   * be of type java.lang.String.
   * @param deployableObjectPart a deployable object part representing a Web Dynpro application
   * @param urlParameters key/value pairs added as URL parameters; they must be of type String
   * @return the workload balanced application URL for the specified
   * <code>deployableObjectPart</code> with appended URL parameters given by <code>urlParameters</code>
   * @throws WDURLException if the URL couldn't be generated
   * @see com.sap.tc.webdynpro.services.sal.url.api.WDURLGenerator#getWorkloadBalancedApplicationURL(WDDeployableObjectPart)
  public static String getWorkloadBalancedApplicationURL(WDDeployableObjectPart deployableObjectPart, Map urlParameters) throws WDURLException {
    return AbstractManager
      .getServerPlatformImplementation()
      .getURLGeneratorFactory()
      .getURLGenerator()
      .getWorkloadBalancedApplicationURL(deployableObjectPart, urlParameters);     
Before i forget it to mention, these are two methods of the WDURLGenerator API. There are others where you don't have to specify the deployableObjectPart, you can use DPO name and name of application as parameters instead.
Hope that helps.
Best regards
Stefan
PS: This was my 2nd attempt, i hope i got you right now...
