SERVLET
public class test extends HttpServlet {
   @EJB
   private LocalBean lookupBean;
    protected void processRequest(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        response.setContentType("text/html;charset=UTF-8");
        PrintWriter out = response.getWriter();

@Stateless()
public class Bean implements BeanLocal {
    @PersistenceContext()
    private EntityManager em;
     public Collection<Item> getMyCollection() {

    }    and if you create an instance of your servlet you'll have to reinitialize LocalBean
@EJB(name="myejbref", beanInterface=BeanLocal.class)
private BeanLocal lookupBean;
private BeanLocal getLookupBean() {
if(lookupBean == null) {
try {
InitialContext ic = new InitialContext();

How to return rows from tmp table created inside function??

Hi,
I'm trying to return rows from a cursor or table (created within
the function). How do I specify the return type?

Hi,
Here is the code that examples to create a function that can
return data from table.This is achieved using REFCURSOR concept.
Hope this helps you.I'm giving all stuff in single PL/SQL
block.You can break it and create a package and declare
refcursor type and function in that as well.
DECLARE
-- Declare generic cursor type
TYPE gencur_type IS REF CURSOR ;
-- Declare generic cursor varaible
gencur gencur_type;
-- Declare record type
TYPE rec_type IS RECORD(descr emp.ename%type) ;
-- Declare record type variable
rec rec_type;
--This how you declare a local function that returns gencrtype
data set
--This function is called in main block
FUNCTION call_refcur return gencur_type
AS
          rr gencur_type;
BEGIN
     OPEN rr FOR SELECT descr FROM emp;
     RETURN rr;
END;-- end of local function
-- Main block begins here
BEGIN
-- Call the local function so that gencur will have
-- the data set returned by select statement
gencur:= call_refcur;
-- Open a loop to test the stuff
LOOP
     FETCH gencur INTO rec;
     EXIT WHEN gencur%NOTFOUND;
     null;
     dbms_output.put_line(rec.ename);
END LOOP;
END;

Oracle forms 9i - How to return back from a block?

Some one please help me
In a trigger, I have a code says go_block. How to return from the block and back to the trigger to continue executing the codes below the go_block statement? Please see example below, I want to come back from block CHECK_STUFF and continue execute the statements
:Name.option := '1';
if :name.option = '1' then
Example:
Block: Name
Item: yes_no - Key-next-item trigger
declare
begin
go_block('check_stuff');
go_item('answer');
:Name.option := '1';
if :name.option = '1' then
Thanks - Patty

The code behind the GO_BLOCK is executed immediately after the GO_BLOCK, it doesn't stop at that point. So you have to split your code, like
declare
begin
go_block('check_stuff');Then, create a procedure like
PROCEDURE PR_RETURN_FROM_BLOCK IS
BEGIN
go_item('answer');
:Name.option := '1';
if :name.option = '1' then
END;Then, when returning from the block (in whatever trigger you use), just call that procedure.

How to return error from subscription function of an event

I am creating a subscription function for an oracle shipped event, oracle.apps.eng.cm.changeObject.submit. The event fires fine, i can do my custom validations in this function. In case the validations fail, I need to return an error message.
As per the guides and metalink documents, the way to do this is by returning 'ERROR' . But even though I return an ERROR, it does not error out. Whether I return SUCCESS or ERROR , the behaviour is the same.
While creating the subscription function, for On Error , I selected, "Stop And Rollback ".
Is it possible to return errors from the subscription functions.
thanks

You shouldn't be passing ResultSet objects across the EJB layer.
Instead you should be passing data back and forth.
All of the data access code should be in one place in one class.
That class should open the connection, run the query, process/store the results of the query and then close the connection.
In this case you probably want to return a list of something to your jsp.
So your EJB call should be more like
public List<resultBean> check(String id){
ResultSet rs = Statement.("select * from table1 where id=123");
List resultList = new ArrayList();
while (rs.next()){
    Bean myBean = new Bean();
    myBean.setProperty1(rs.getString("field1"));
    myBean.setProperty2(rs.getString("field2"));
    resultList.add(myBean);
return resultList;
}

How to return fault from Async BPEL

Hi,
I have ESB that has input,output and fault, This ESB calls Async BPEL that takes only input. Now i want to return fault from BPEL to ESB. How do i do it?
Please help.

Hi,
My use case is i am implementing AIA. So my enterprise layer is ESB and my ABCS provider is BPEL. As provider takes lot of time to complete the instance, to avoid timeout issue i just created Async BPEL with two ports one for input another for fault. I am able to send back my fault back to this call back port. But how i can receive the fault to the same ESB which called the BPEL?
I am not able to implement it. I can not go for any workaround like creating one more BPEL and then make it as sync, put pick activity and receive the fault then send back to ESB.
Thats the reason i am very specific. If you find some solution please let me know.

How to call JSp from Servlet??

Hello,
I want to call JSP page from servlet.I am using Visual Age For java 3.4. What is wrong in my code??
if (userExists) {
f.setErrors("userName","Duplicate User: Try a different username");
getServletConfig().getServletContext().
getRequestDispatcher("/jsp/forms/retry.jsp").
forward(request, response);
I am not able to get the o/p. Pls help.

I can't see anything obvious, but did you take any steps towards doing output before this code (like openning an output stream)?
Not clear what f.setErrors does - presumably stuffs the error message in an attribute of the request.

How to return data from Ejb as collection to Front End application.

Hi,
I am creating a J2ee application. Here i am accessing BAPIs using stateless session bean through JCO connection. Now the BAPI is returning a return Table and return Structure to the EJB.
I have coded the following code in one of the Ejb Method as follows:
JCO.Table returnTable = null;
JCO.Structure returnStructure = null;
JCO.ParameterList paramList = siteBAPI.getExportParameterList();
JCO.ParameterList paramList2 = siteBAPI.getTableParameterList();
returnTable = paramList2.getTable("SITE_SUBSITE_INSTL");
returnStructure = paramList.getStructure("BAPIRET2");
Now i want to sent this data( returnTable & returnStructure) to front end application where front end developer accessing this returned data using Jsp.
My scenario is that , first i want to convert this returnTable & returnStructure in a single collection and then sent this collection to Front end.
My aim is that , the front end the application should not receive the Data, using JCO.table Variable but as a single Collection.
I am using NWDI-2004s sps10.
i need urgent help on this issue and i would really appreciate if somebody can put the answer with some sample code on how to return the data as Collection.

if you want to return a result, then you probably shouldn't be using a message bean. message beans for for asynchronous tasks. session beans for for synchronous tasks. thus it would make much more sense to have your jsp call the session bean directly.
