EJBs and Web pages

Hi Everyone,
I am attempting to run my jsp with code from my EJB. The following error occurs.

Can't make static reference to method java.util.Vector getAccountsList() in class.

This is my jsp code:
<select name...>
<%
for(int i=0;i<StorAccountsListView.getAccountsList().size();i++) {
String accounts = (String)StorAccountsListView.getAccountsList().elementAt(i);
%>
<option><%=accounts%></option>
<%
}
%>
</select>

My EJB StorAccountsListView.java has
public Vector getAccountsList() {
return accountsList;
}

I am very new to this and ANY help would be most appreciated. Please remember I don't have the verbal jargen down yet.

Thanks for your help!
Tim

You'll first have to instantiate the class. Normally this works via the following:

StorAccountsListView view = new StorAccountsListView(...params...);
Vector v = view.getAccountsList();

With EJBs in JSPs it's a little harder (wow - you started with the hard stuff, didn't you?):

You'll have to get the beans in the .jsp even before the <html> tag via code pretty much like the following (copied without modification from a project I'm working on - this code works if the EJB classes have the right names

):

<ejb:useHome id="uhome" type="project.bean.UserHome" location="UserHashBean" />
<ejb:useBean id="user" type="project.bean.UserRemote" scope="session">
<ejb:createBean instance="<%=uhome.create(request.getParameter(\"username\&quot

)%>" />
</ejb:useBean>

You could then access the bean (actually the remote interface) via the name "user" (without the ""s). This would then give:

Vector v = user.getAccountsList();

Phew - hope I did help a little... allow thyself to be the spark that lights the fire
