Scope/Class referencess

Question

Ok... I have been converting my application with static variables to instance(?) variables and I'm running into issues. I really hope someone can help.
I had static variables with one thought in mind, but do to the fact that it causes problems with the multiuser arena, I was changing them back...
I have: 1) a login.jsp that stores the login information of a person; 2) main.jsp that contains calls to 3 different classes; 3) loginInfo class that holds login info; 4) SCR_Info class that contains some business logic for the app; 5) StrReqEntImpl that is the meat of the business logic for the Entity (Database connectivity)...
main.jsp
<jsp:useBean id="login" class="com.vs.lmco.ASD.connection.loginInfo" scope="session" />
<jsp:useBean id="scr" class="com.vs.lmco.application.SCR.SCR_Info" scope="session" />
<jsp:useBean id="scrView" class="com.vs.lmco.application.SCR.StrReqEntImpl" scope="session" />
scr.setLogin(login);
scrView.setSCR_Info(scr);
Inside of the doDML of , I have StrReqEntImpl:
setRequestorId(new Number(scr.getPaxId()));
Ok, I put a println statement when the scrView.setSCR_Info(scr) is called. It prints com.vs.lmco.application.SCR.SCR_Info@81, like it should. Then I make a modification to the record via JSP and try to commit it. I did another println which displays a null value. The class instance of the SCR_Info is lost when I try for the commit.
Can anyone help with my logic and how I can solve the problem?
Thanks in advance,
Jim

I think that I may have found a solution... There might be a better way, and maybe this will be able to get someone else thinking about something related...
Ok, I have my jar file which contains now loginInfo & a new staticLoginInfo. My loginInfo contains all of the instance variables; whereas the staticLoginInfo contains static references to the instance class.
ASD.jar - staticLoginInfo.java:
private static Vector reference = new Vector();
public static int setUp(loginInfo login)
int seq = reference.size();
reference.add(seq,login);
return (seq)
public static loginInfo getLogin(String seq)
return ((loginInfo)(reference.get(Integer.parseInt(seq))));
Now I have a war file that contains contents.jsp which contains links to the different applications that the logged in user has access to.
ASD.war - contents.jsp:
seq = staticLoginInfo.setUp(login);
<a href="/SCR/SCR_Role.jsp?seq=<%=seq%>">...
Now my SCR.war file contains SCR_Role.jsp that shows different "roles" that that person has within the application...
SCR.war - SCR_Role.jsp:
loginInfo tLogin = (loginInfo)staticLoginInfo.getLogin((String)request.getParameter("seq"));
login.setUsername(tLogin.getUsername());
login.setPassword(tLogin.getPassword());
login.setDatabase(tLogin.getDatabase());
Believe it or not, this works. I thought that I would be able to just put login = (loginInfo)staticLoginInfo..., and this works for each page that I put this in; but by setting a temporary variable (tLogin), it carries throughout the rest of the application...
Thanks for all the help for those that tried...
