Having prooblem with accessing EJB from JSP

Hi Guys

I have a JSP in which i need to get data From an Access Bean. Now in the access bean I call the finder method findByStoreId(storeId). This method gives me the whole ejb and then I need to call the getCRId() method to get only the id's and store it in a hashtable

i started with something like this, would anyody please help me how I can complete the code and if there is a way to get the id using usebean in JSTL. I would really appreciate any kind of help

Thanks

SRSCashRegisterAccessBean crBean = new SRSCashRegisterAccessBean();
                  
                  Enumeration en = crBean.findByStoreId(new Long(storeId.substring(3,storeId.length()-8)));
                  while (en.hasMoreElements()) {
                        crBean = (SRSCashRegisterAccessBean) en.nextElement();      
//Todo
call the getCrId() method and store data in a hashtable
//end Todo
}

Do you want all above code in jstl?
or if in jsp you have SRSCashRegisterAccessBean bean ?

using finder methods will be heavy for such senario's.
you can write a Home Business method to fetch all the Crid's as a collection object.

write a business method in home interface and in the bean class use ejbselect methods to query the database for all the crid's and return them as a collection object.

I dont think you can create class in jstl.
SRSCashRegisterAccessBean crBean = new SRSCashRegisterAccessBean();
                  Enumeration en = crBean.findByStoreId(new Long(storeId.substring(3,storeId.length()-8)));

Above portion is difficult to convert in jstl.
It is not possible to pass parameter in method in jstl.
When you get list that  is possible to iterate using forEach tag of jstl
