Find session id from Webdynpro in 04s?

Do you know how to find the j2ee session id from webdynpro?
In NW 2004, we used this code:
          HttpServletRequest request = ((IWebContextAdapter) WDWebContextAdapter.getWebContextAdapter()).getHttpServletRequest();
          HttpSession session = request.getSession();
          String sessionId = session.getId();
How can you find this using 2004s with the IWDProtocolAdapter class??

Hi,
Modifying your posted code a bit:
HttpServletRequest request = (HttpServletRequest) WDProtocolAdapter.getProtocolAdapter().getRequestObject().getProtocolRequest();
HttpSession session = request.getSession();
String sessionId = session.getId();

Call stateless session bean EJB 2.0 from Webdynpro Java UI

Hello,
Can someone please tell me asto how to call a stateless session bean EJB 2.0 from Webdynpro Java UI?
The NWDS version is 7.0.
Thanks and Regards,
Arya

Hi Aryadipta
Please check this pdfs
https://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/b00917dc-ead4-2910-3ebb-b0a63e49ef10&overridelayout=true
Steps for calling stateless session bean in Webdynpro java
Go to NWDS -> open perspective ->j2ee
select EJB Module Project ->create a project with name
Open the Project -->RC on ejb-jar.xml -> Select new --> EJB
Give name to EJB Bean (First letter should be in capital letters)
select the type of bean as Stateless session bean and give the package name to store that EJB bean.
After that Expand ejb-jar.xml and then select the <projectEJB>
Double click on this on method tab double click you will get business method where we will create the methods for business logic
Double click on projectEJB and then RC on bean tab and write required business logic in bean window as follows(based on requirement we will design a business logic).
After writing the business logic go to project -> rebuild
Till now we have created one EJB jar file
then go to File-->Enterprise Application Project -->create a project (projectEAR)
After creating a project click on next-> here we will have ear projects and then we select specific project required for our application.(here select projectEJB)
After that Calculate EAR project will be available on j2ee explorer.
Right click on <Bean> here
select New->Web Service->give a name to webservice and select Default configuration type as simple SOAP
-->click next -> Finish.
That webservice and related are created in ejb-jar.xml .
Expand the ejb-jar.xml.and double click on < webservice>
RC ProjectEJB -> Build EJB Archive RC on CalculateEAR ->Build applicationarchive.
Expand the projectEAR->RC on CalculateEAR.ear->Deploy to J2EE Engine
Double click on calculateEAR.ear ->Webservice navigator tab ->we eill servers expand the node
select the specific WebService
Here we test the webservice by click on Test and test it.
After that go to Web dynpro perspective ->create one webdynpro Project and one component
RC on model> Select import Web Service model(last)>give model name and package
and select radio button as local file system or URL
Go to WSnavigator->copy the WSDL path and paste it in model WSDL path and click on finish.
from here onwards steps are same as that adaptive RFC model
Hope it helps
Thanks

Capturing session id in WEBDYNPRO environment

Hi Friends,
I am trying to pass the parameters from webdynpro to BSP using the set server cookies technique. Initially i did it through the same technique from BSP to Webdynpro and i am successful in it. However i am unable to apply the same from webdynpro to BSP.
Below is the one i am using.
CALL METHOD cl_bsp_server_side_cookie=>set_server_cookie
    EXPORTING
      name                  = 'modeldata2'
      application_name      = application_name
      application_namespace = application_namespace
      username              = username
      session_id            = session_id
      data_name             = 'modeldata2'
    importing
      data_value            = ostream.
Here the parameter 'session_id' is picked up from the available RUNTIME object of BSP. And rest of all parameters are some string constants which i could find out.
What is the equivalent object for RUNTIME in webdynpro?
And how do i get the session id in the webdynpro environment.
Any inputs on this?
regards
Nalinikanth.

Thanks for all tthe people who took a look at my question patiently. I got the resolution for the question. I missed out putting the cookie retention time while setting the cookie.

Servlet from Webdynpro

Hi,
Anyone tried launching a servlet from a webdynpro application.
Were you able to manage the session in both the applications?

We are using similar kind of application where we are lauching a servlet from WebDynpro application. But our application was not required to maintain common session.
But I guess its possible to do so, you can try this:
String servURL = WDWebContextAdapter.getWebContextAdapter().encodeRedirectURL("/applicationcontext/servletalias?requestparameters");
IWDWindow window = wdComponentAPI.getWindowManager().createExternalWindow(servURL,"Title here",false);
window.setWindowSize(1024,640);
window.setWindowPosition(WDWindowPos.CENTER);
window.open();
You can find documentation for
<a href="https://help.sap.com/javadocs/NW04/current/wd/com/sap/tc/webdynpro/services/sal/adapter/api/IWDWebContextAdapter.html#encodeRedirectURL(java.lang.String)">WDWebContextAdapter.getWebContextAdapter().encodeRedirectURL</a>

Error when Interative Adobe Form is called from Webdynpro ABAP.

Hi Experts,
I trying to call a Interactive adobe form from ABAP Webdynpro application but I am facing the below error.
Line: -
The following error text was processed in the system GJD : User session (HTTP/SMTP/..) closed after timeout
The error occurred on the application server az18u021_GJD_01 and in the work process 0 .
The termination type was: ERROR_MESSAGE_STATE
The ABAP call stack was:
Method: PREPROCESS_REQUEST of program CL_WDR_CLIENT_ABSTRACT_HTTP===CP
Method: IF_HTTP_EXTENSION~HANDLE_REQUEST of program CL_WDR_MAIN_TASK==============CP
Method: EXECUTE_REQUEST_FROM_MEMORY of program CL_HTTP_SERVER================CP
Function: HTTP_DISPATCH_REQUEST of program SAPLHTTP_RUNTIME
Module: %_HTTP_START of program SAPMHTTP
Line: -
When I uncheck the enabled property of the Interactive From in the Page of the WebDynpro I am able to execute the application successfully.But the Adobe form behaves as a Static Form when I uncheck the enabled property.
So kindly provide your valuable suggestions to avoid the above error when I am calling a Interactive adobe form from Webdynpro ABAP.
Thanks in Advance.

Hello,
Hello, are you sure you have your ADS credentials configured correctly and valid? I guess you know that is the only difference between clicking enabled on true or false. If you are not sure, you can use SE38, search for FP_* and pick some reports to check the licencing. The names of the reports are good enough to recognize the right one.
Or maybe that is a security problem? Have you checked the ADS_ERROR string? Did you use the ADS trace?
check: http://help.sap.com/saphelp_nw70/helpdata/en/2c/241a427ff6db2ce10000000a1550b0/content.htm

Re: [iPlanet-JATO] Re: onBeforeRequest(); Finding requested view from requestContext

If you want to stop a JATO request in its tracks, you have a little black
magic at your disposal: you can throw a CompleteRequestException. This
indicates to the JATO infrastructure that it should immeditately stop
handling the request, but not generate an error, as the develper has taken
full control. You can generally throw this error from anywhere, at any
point--it is a RuntimeException, and is "tunneled" through other exception
handlers where appropriate.
In your scenario, you want to check if the user is logged in, and if not,
save the target URL using the parsePathInfo() method. Then, forward to the
login page and then throw a CompleteRequestException.

I guess what I am thinking about doing is capturing the requested URL,
i.e. /appname/modulename/RequestName. In the onBeforeRequest(). I
would then check to see if the user is logged in, and if not, set the
URL in the session(or page session of the Login bean) and forward to
the Login viewbean using the viewbean manager. Inside the login view
in the handleSubmit() method I would authenticate the user and then
get the URL out of the session (or pagesession). I would then
magically get the ViewBean/Command object for the URL or otherwise
"forward the request" as if the user had typed in
/appname/modulename/RequestName, which is the behavior I am trying to
acheive.
It turns out I cannot forward in the onBeforeRequest() as it will
output the viewbean and then continue to process the request which in
turn trys to do a RequestDispatcher().forward after data has been
written to the stream which does not bode well with the servlet
container. Thus, it appears I have no control of the request in the
onBeforeRequest() method. Is this correct?
In light of this new observation I am now going to create a base view
class that all views will extend from and override the
onSecurityCheck() method to forward to my login bean. If I can't find
any other way, I will get the URL from the page session and do a
response.sendRedirect() to the URL.
Thanks for the help!

What you do know is which "page" (view bean) the request is coming from

HttpServletRequest. The attribute name is "viewBean".
So you can get the view bean name by doing the following inonBeforeRequest:
<HttpServletRequest>.getAttribute("viewBean");
But I suspect this is not going to solve your current issue.
You could add the target page name to the page session. If there ismore
than one possible target page, it might get a little more involved.
Let me know if the use of page session needs further explanation.

Passing Parameters via Post Method from Webdynpro Java to a web application

Hello Experts,
I want to pass few parameters from a web dynpro application to an external web application.
In order to achieve this, I am referring to the below thread:
HTTP Post
As mentioned in the thread, I am trying to create an additional Suspend Plug parameter (besides 'Url' of type String) with name 'postParams' and of type Map.
But when I build my DC, I am getting the same error which most of the people in the thread have mentioned:
Controller XXXCompInterfaceView [Suspend]: Outbound plug (of type 'Suspend') 'Suspend' may have at most two parameters: 'Url' of type 'string' and 'postParams' of type 'Map'.
I am using SAP NetWeaver Developer Studio Version: 7.01.00
Kindly suggest if this is the NWDS version issue or is it something else that I am missing out.
Also, if it is the NWDS version issue please let me know the NWDS version that I can use to avoid this error.
Any other suggestion/alternative approach to pass the parameters via POST method from webdynpro java to an external web application apart from the one which is mentioned in the above thread is most welcome.
Thanks & Regards,
Anurag

Hi,
This is purely a java approach, even you can try this for your requirement.
There are two types of http calls synchronous call or Asynchronous call. So you have to choose the way to pass parameters in post method based on the http call.
if it is synchronous means, collect all the values from users/parameters using UI element eg: form and pass all the values via form to the next page is nothing but your web application url.
If it is Asynchronous means, write a http client in java and integrate the same with your custom code and you can find an option for sending parameters in post method.
here you go and find the way to implement Asynchronous scenario,

How to find session of process executed

My requirement is i want to find out logs with user or session information. This is required to find out concurrency issues of process.
I have tried with v$session, however from that table i m not able to find out particular session. Please help.
Thanks in advance

In a 3 tier architecture the database tier sees the application tier as the client - not the presentation layer user. The data tier has no idea what is beyond the application tier.
If you want the data tier to know who/what the presentation tier client is, the application tier has to pass that data to the data tier.
One method in Oracle is for the application tier to use the [SET_CLIENT_INFO|http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_appinf.htm#CHEJCFGG] call of the DBMS_APPLICATION_INFO PL/SQL package.
Another method is to use a CONTEXT to set name-space variables in that Oracle session equal to end-user details.

How to call session EJB from EP service in EP 7.0?

Hi,
I am trying to invoke stateless session EJB from my portal service. Both the service and EJB are deployed on the same server which is EP 7.0.
I found [this|http://help.sap.com/saphelp_nw70/helpdata/EN/42/9ddcc9bb211d72e10000000a1553f6/frameset.htm] in SAP help and tried to implement it (added PrivateSharingReference to portalapp.xml and implemented the code), but everytime I try to lookup the session bean and cast it using P4ObjectBroker.narrow() method, I get java.lang.ClassCastException. The object found in JNDI and my portal service have different classloaders, so I suppose this is the problem, but I don't know how to handle it...
Can anyone please help me?
Regards,
Tomas

Problem in connecting to database from webdynpro for java

Hi
I have a problem in connecting to database from webdynpro application
I am using oracle 10 express edition as database and was able to connect to database from a java application.But was unable to connect from a webdynpro for java.
<b>I guess webdynpro for java uses open sql instead of vendor sql(I looked in the visual admin ,DB is using open sql) so unable to connect to database.Am i right.?</b>
Do i need to make any settings in the visual admin to make it work?
How to solve this problem.Please give me pointers
Thanks
Bala

Hi,
For connecting to Oracle, either you can use the normal JDBC connectivty code directly which is given below :
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@Oracle_server_ip:Oracle port:SID of the Database","user_name","password");
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("your query");
In case you want to fetch data through ejbs, these are the steps to be followed :
1) Open the J2EE perspective
2) Create an EJB Module project
3) Right click on ejbModule, create a new EJB (select your EJB type)
4) While creating the ejb itself, you can add business methods by clicking Next in the UI. Another option is after creating the ejb, write the method in the bean, then select the method from ejb-jar.xml -> <bean name> ->method. Right click and select propogate to local & remote.
5) Double click on ejb-j2ee-engine.xml. select your bean and specify a Jndi name for eg: MyJndi.
6) Right click on the EJB project and add classes12.zip file (provided by Oracle) to its build path. (under libraries tab). Also check the same file under Order & Export.
7) Create an Enterprise Application project.
8) Right click on the EJB module project and select add to EAR project, then select the created EAR project.
9) Right click on the EJB project, select Build EJB Archive
10) Right click on the EAR project, select Build Application Archive
11) Open the WebDynpro perspective, open a new project, right click on the project ->properties. Do the following configurations :-
Java Build path - select the EJB project from projects , check the selected project under Order & Export
Project references select the EAR project
WebDynpro references select sharing references tab, click add & make an entry as : <vendor>/<EAR project name without .ear extension>
You can find the vendor name under application-j2ee-engine.xml file of the EAR project. By default it is sap.com. So if my EAR projects name is ABC, my entry would look like sap.com/ABC
12) Now the configurations are over and the EJB can be invoked by writing the client code inside the webdynpro component. Like:
InitialContext context = new InitialContext();
Object obj = context.lookup("MyJndi");
MyEJBHome home = MyEJBHome)PortableRemoteObject.narrow(obj,MyEJBHome.class);
MyEJB mybean = home.create();
int a = 0;
a= mybean.add(10,15);
wdContext.currentContextElement().setSum(a);
where MyEJB is my EJB name and MyJndi is my JNDI name
To connect to Oracle , you can write the usual Java code (given below) as a business methos of the ejb (similar to add() method in the example). And access it like mybean.<businessMethodName>().
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@Oracle_server_ip:Oracle port:SID of the Database","user_name","password");
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("your query");

Problem when calling session bean from main.

Hi everyone
I get the following error when calling a session bean from main(String args[]).
Sep 3, 2008 9:11:13 AM com.sun.enterprise.appclient.MainWithModuleSupport <init>
WARNING: ACC003: Application threw an exception.
java.lang.NullPointerException
at databasetest.Main.main(Main.java:26)
Here is my code beneath.
I'm using netbeans and glassfish application server.
Everything is in the same project, called DatabaseTest, I also have deployed the application before running the client.
I'm running the client as follows, right click on the DatabaseTest-app-client and select run.
The client:
package databasetest;
import com.test.UsersFacadeRemote;
import javax.ejb.EJB;
import com.test.Users;
public class Main {
    @EJB
    private static UsersFacadeRemote usersFacade;
    public static void main(String[] args) {
        Users users = new Users(12, 34);
        usersFacade.create(users);
}The remote facade I'm calling:
package com.test;
import java.util.List;
import javax.ejb.Remote;
@Remote
public interface UsersFacadeRemote {
    void create(Users users);
    void edit(Users users);
    void remove(Users users);
    Users find(Object id);
    List<Users> findAll();
}The stateless bean:
package com.test;
import java.util.List;
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
@Stateless
public class UsersFacade implements UsersFacadeRemote {
    @PersistenceContext
    private EntityManager em;
    public void create(Users users) {
        em.persist(users);
    public void edit(Users users) {
        em.merge(users);
    public void remove(Users users) {
        em.remove(em.merge(users));
    public Users find(Object id) {
        return em.find(com.test.Users.class, id);
    public List<Users> findAll() {
        return em.createQuery("select object(o) from Users as o").getResultList();
}

looks like you're banging your head against the same brick wall as [I have done|http://forums.sun.com/thread.jspa?forumID=13&threadID=5317110] and [others have in the past|http://forums.sun.com/thread.jspa?forumID=136&threadID=5259913] if that's any consolation.
Funny thing is, mine did actually work in the debugger but not when running!
Strange thing that.
I did initially interest someone from the developers but they couldn't really help, ended up saying : try instantiating your beans the EJB 2.1 way and see where that gets you. Yes that works but they promised us "hey no more dopey xml deployment descriptors just some cool annotations" didn't they?
I've got the feeling were' missing something really obvious!

Looking up of a stateless session bean from an MDB

Hi,
I have been trying to invoke a method on a stateless session bean from an MDB on receipt of a message from a queue. The bean receives the message. Then it gets the initial context, but after this the following message appears:
javax.naming.NamingException: Error instantation environment context for Message DrivenBean MyMDB: No location specified and no suitable instance of the type 'MySessionRemote' found for the ejb-ref <mySessionBean> at com.evermind.server.ejb.MessageDrivenHome.getEnvironmentContext(MessageDrivenHome.java:559)
The session bean is in a seperate ear file. These are the deployment descriptors of the MDB:
ejb-jar:
<ejb-jar>
     <description>A Message-Driven Beans</description>
     <enterprise-beans>
     <message-driven>

The lookup name which I give in MDB is:
java:comp/env/MySessionEJB

Hi,
    Thanks for your replies.I did as you had suggested.I added ejb-local-ref to the ejb-jar.xml and i provided ejb-ref as MyBean.
My lookup code uses the string
ctxt.lookup("localejbs\MyBean");
But still i get Naming Exception.
I tried something different yesterday.
I changed the code to use
InitialContext ctxt = new InitialContext();
ctxt.lookup("localejbs/"+ pathfromJNDIRegistry);
and this time i did not get Naming exception but i got RemoteException saying there was error loading the class.
Is there something i need to add somewhere for the classloader to be able to find and load this class in the second scenario.
Please suggest me which method to go for amongst the two and what is the missing information i need to add.
Thanks
Priya
