Hi all,

I inserted an HTTP destination in the Destination Service (Visual administrator) and I need to get it in my Java Web Dympro. I found this code:

	DestinationService dstService = (DestinationService)
	ctx.lookup(DestinationService.JNDI_KEY);
	if (dstService == null)
	throw new NamingException("Destination Service not available");
	Destination destination = dstService.getDestination("HTTP","sso_givaudan_OpportunityLink");
//	  for HTTP destination: cast
	HTTPDestination httpDestination = (HTTPDestination) destination;
//	  obtain a HTTPUrlConnection from the destinationHttpURLConnection
	httpConnection = httpDestination.getURLConnection();

I imported all the libraries, but NetWeaver underline in red the follow:

ctx : cannot be resolved

Why?? Thanks for your help.

Vito

Hi,

>>"httpConncetion cannot be resolved!!!" what type is httpConnection ?? WHat library I have to import??

The type of httpConnection is HttpURLConnection.

You need to import this <b>java.net.HttpURLConnection</b>.

Hi Uma,

I'm tring to catch the URL set in the Visual Administrator, in the Destination service.

I added the following code with no sintax error:


	try {
	InitialContext ctx = new InitialContext();	
	DestinationService dstService = (DestinationService) ctx.lookup(DestinationService.JNDI_KEY);
	if (dstService == null)
	throw new NamingException("Destination Service not available");
		
	try{
	Destination destination = dstService.getDestination("HTTP","sso_givaudan_OpportunityLink");
	//for HTTP destination: cast
	HTTPDestination httpDestination = (HTTPDestination) destination;
		
	//obtain a HTTPUrlConnection from the destinationHttpURLConnection
	HttpURLConnection httpConnection = httpDestination.getURLConnection();
	urlOpportunityLink = httpConnection.toString(); //return the http address
	} catch (IDException ex) {}
	  catch (RemoteException ex) {};
	} catch (NamingException e) {};
	
	wdContext.getCurrentElement().setAttributeValue("OpportunityLink",urlOpportunityLink);

When I launch the application (Java WD) I have the follow exception:


An error has occurred: 
"Failed to process the request."

Please contact your system administrator.

Vito,

This could be caused by class loading issues.

Please check the following document: http://help.sap.com/saphelp_nw04/helpdata/en/17/d609b48ea5f748b47c0f32be265935/content.htm

Section "Prerequisites" outlines necessary references that must be added.

Also make sure that you are using classes from package com.sap.security.core.server.destinations.api, not from others.

Hi Valery,

just others two questions for you.

1. In the documentation you suggested me is used:

httpConnection = httpDestination.getURLConnection();

This give me an error, because no library exist. Where I can find the right library for this?

2. This is a more complex question

My application is a Portal Panel that contains three tabs. When the user click on each tab a BSP is called. I do this setting a bsp http address for each tab. Now I will get the address, us string, using httpConnection.getUrl

I don't known if this is a correct way to call an external bsp, because <u>I need to call the BSP warranting the single sign-on.</u>

Perhaps, I need to open a connection to Destination URL (Note that I have: VisualAdministrator->Destination->LogonTicket authentication, and in the Security Providere->Ticket->CreateTicketLoginModule in oreder to assure the sso for my Web Dynpro).

How can I to open the BSP into the tab, using the HTTP Destination API??

This is the first time I'm working on this. I will appreciate your help.

Thanks,

Vito

Vito,

Sorry, it seems that I give you only one link instead of two.

First one:

http://help.sap.com/saphelp_nw04/helpdata/en/8b/8e7dac1e661d44bf2a676fd3948cc6/content.htm

Cut from the text:

<i><b>Prerequisites</b>

All Destinations

Your application needs classloader references to tcsecdestinationsservice and tcsecdestinationsinterface.

- For J2EE applications, add the references in the Developer Studio as described in Referencing Libraries in Applications.

- For Web Dynpro applications, add the components security.class and tc/sec/destinations/interface to your projects’ classpaths as described in Implementing the Server Abstraction Layer. Add the references as service and interface references accordingly.</i>

Second:

http://help.sap.com/saphelp_nw04/helpdata/en/17/d609b48ea5f748b47c0f32be265935/content.htm

Cut from its text:

Valery,

I have inserted the follow in the JWD (but seems to be the same):

WedDynproReferences:

->Interface references: tc/sec/destinations/

->Service references: security.class

Is this right??

My code is:


import java.net.InetAddress;
import java.net.UnknownHostException;

import javax.naming.NamingException;

import com.sap.givaudan.navigation.comp.wdp.IPrivateNavigationComp;

InitialContext ctx = new InitialContext();
	DestinationService dstService = (DestinationService) 
		ctx.lookup(DestinationService.JNDI_KEY);
    
		if (dstService == null)
			throw new NamingException("Destination Service not available");
    
		Destination destination = dstService.getDestination("HTTP","dst-1");
		//for HTTP destination: cast
		HTTPDestination httpDestination = (HTTPDestination) destination;
		//obtain a HTTPUrlConnection from the destinationHttpURLConnection
	    httpConnection = httpDestination.getURLConnection();
		//String url = httpDestination.getUrl();

I have the error on this row:

<i>httpConnection = httpDestination.getURLConnection();</i>

<i>"httpConnection cannot be resolved"!!!</i>

I have imported libraries: "Java build path -> Add external JARs"

I really don't understand what I wrong.

Thanks,

Vito,

Do you get this error at build time or when you deploy appliation and run it???

Also your references is wrong:

Interface references:

<b>tcsecdestinations~interface</b>

(according to "destinations_api" interface properties shown in VisualAdministrator)

Library references (it is not service!):

<b>security.class</b>

Also I provide references without "sap.com/" prefix (vendor name) you may try both reference <b>with</b> such prefix in case of errors.

Sorry Valery, I'm not so smart in this.

I have set as you suggested:

- Interface references: tcsecdestinations~interface

- Library references: security.class

TRegarding the error, the netweaver underline in red the httpConnection in the line:

httpConnection = httpDestination.getURLConnection();

and says: "http connection cannot be resolved". Perhaps I have to imort a particular library (??) and give a type to httpConnection (fpr example HttpURLConncetion ??)

Thanx,

Now it is clear: you get error at build-time.

Keep references as I suggested, but now please clarify the following:

<i>I have imported libraries: "Java build path -> Add external JARs"</i>

Could you name libraries you have added??? (exact jar names with path, you can ommit path till ".dtc" or "eclipse" directory).

Valery,

I have added the follow external Jar:

C:\Program Files\SAP\IDE\IDE70\eclipse\plugins\com.sap.tc.ap_2.0.0\comp\SAP-JEE\DCs\sap.com\tc\sec\destinations\interface\_comp\gen\default\public\default\lib\java\tc_sec_destinations_interface.jar

for the follow import (like suggest the documentation):

-import com.sap.security.core.server.destinations.api.DestinationService;

-import com.sap.security.core.server.destinations.api.Destination;

-import com.sap.security.core.server.destinations.api.HTTPDestination;

Instead the following seems that are not used:

-import com.sap.security.core.server.destinations.api.DestinationException;

-import com.sap.security.core.server.destinations.api.RFCDestination;

The problem is on the follow line yet:

httpConnection = httpDestination.getURLConnection();

"cannot be resolved"

thx,

I misread your code, the line should be either:

or

java.net.URLConnection httpConnection = httpDestination.getURLConnection();

Valery,

no more errors. The code now is:

	try {
	InitialContext ctx = new InitialContext();
	DestinationService dstService = (DestinationService) 
		ctx.lookup(DestinationService.JNDI_KEY);
		if (dstService == null)
			throw new NamingException("Destination Service not available");
    	
    	try{
		Destination destination = dstService.getDestination("HTTP","dst-1");    	
		//for HTTP destination: cast
		HTTPDestination httpDestination = (HTTPDestination) destination;
			try {
			//obtain a HTTPUrlConnection from the destinationHttpURLConnection
			java.net.HttpURLConnection httpConnection = httpDestination.getURLConnection();
			} catch (ConfigurationException e) {};
		}catch (DestinationException e) {}
		 catch (RemoteException e) {};
	} catch (NamingException e) {};

Now, what I need, is that when the user click the tab the BSP must appears. The BSP link is in the Destination sercice us HTTP. For this I would like to use:

httpConnection.connect();

on the tab click event. Do you know this is the correct way to call the BSP? Or exist others methods more convenient?

Note that i need the HTTp destination because it use LOgonTicket for single sign-on from the java stack and the abap stack.

Thanks,

Vito

Vito,

Re-write your code to debug exact reason:


Destination destination = dstService.getDestination("HTTP","dst-1");    	
wdComponentAPI.getMessageManager().reportSuccess
(
  "Destination class: " + destination.getClass().getName()
);
//for HTTP destination: cast
if ( !(destination instanceof HTTPDestination) ) return;
HTTPDestination httpDestination = (HTTPDestination) destination;

What is an output of message manager in browser?

Yes, you get ctx correctly.

But what line cause class-cast-exception?

I expected it is Destination->HTTPDestination cast, but it seems that error occurs higher on stack...

Rewrite it as following:

wdComponentAPI.getMessageManager().reportSuccess

if ( !(o instanceof DestinationService) ) return;

Vito,

<i>now the application appears without error :)</i>

This is because functionality is switched-off with "instanceof" check.

I've asked you what is reported by message manager?

You must see this in browser: "DestinationService class: .....". Please post this line here.

Vito,

Ok, it seems that what you actually get from JNDI lookup here is a remote object proxy, it has to be "narrowed" to actual interface. Your code must be:


String url = null;
try 
{
  final InitialContext ctx = new InitialContext();
  final Object o = ctx.lookup(DestinationService.JNDI_KEY);
  final DestinationService dstService =
   (DestinationService)javax.rmi.PortableRemoteObject.narrow
     (
       o, DestinationService.class
     );
 
  try
  {
    final Destination destination = dstService.getDestination("HTTP","dst-1");
    /* for HTTP destination: cast */
    final HTTPDestination httpDestination = (HTTPDestination) destination;
    try 
    {
      url = httpDestination.getUrl();
    } 
    catch (final ConfigurationException e) 
    {
       /* @TODO Handle Exception */
    };
  } 
  catch (DestinationException e) 
  {
     /* @TODO Handle Exception */
  }
  catch (RemoteException e) 
  {
     /* @TODO Handle Exception */
  };
} 
catch (NamingException e) 
{
  /* @TODO Handle Exception */
};
if ( null != url ) 
  wdComponentAPI.getMessageManager().reportSuccess
  (
    "BSP Application URL: " + url
  );
else
  wdComponentAPI.getMessageManager().reportWarning
  (
    "Unnable to find BSP Application URL!"
  );

Try this code, if it works then you will see URL of target BSP application. Loading this URL is a separate complex question...

Sorry, I misguided you.

Actually, there are should be 2 WD references, but no library reference. Instead they are:

Interface reference: tcsecdestinations~interface

Service referenece: tcsecdestinations~service

This way it works for me.
