Refering to object instances from a jsp

Question

How can i call object instances within class instances in my application -- from a jsp?
In other words, i want to reference to an pre-existing application instance of a class.
I do not want "use:bean" -- which will use a class (not the specific instance i am looking for in the application).
I also do not want a binding to a variable only ( #{class.variable} ).
Thank You!

That's a good reminder of how to positively access class2, stevejluke. Thanks.
However, i have found by trying to access a simple String in Class1 that the class1 instantiated by the jsf page (this comes up first in the application and has components which require Class1) is not the same instantiation that being accessed by the jsp page (which is navigated to by a button from the jsf page).
I put:
<jsp:useBean id="myBean" class="com.mycompany.expense.EntryHandler" scope="session"/>
at the top of both the jsf and the jsp page.
faces-config.xml has:
<managed-bean>
<description>
Glue bean for entry related events and the current entry data
</description>
<managed-bean-name>entryHandler</managed-bean-name>
<managed-bean-class>
com.mycompany.expense.EntryHandler
</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
<managed-property> ((about 4)) <managed-property>
<managed-bean>
I tried setting <managed-bean-name> equal to the id in the jsp:useBean tag but drew the an error indicating the the <jsp:useBean ...> tag had instantiated the class before the faces-config.xml file had -- hence the managed property could not be found.
I also tried putting name="entryHandler" in the <jsp:useBean > tag, but this is not allowed.
Hmm, how to get the <managed-bean> and <jsp:useBean> to match?
Maybe i have to put in code to the effect "get context " "get instantiation" etc,
I'll have to try looking it up . . .
