RE: Tomcat/JSP Question
Title: RE: Tomcat/JSP Question
Try putting in get/set methods for the object, then getting them that way, e.g.:
--
public Object getMyObject()
{
return myObject;
}
public void setMyObject(Object _o)
{
myObject = _o;
}
<% Object myObject = EX.getMyObject(); %>
--
The get/set methods will allow introspection.
Or, if you want to just get it directly, you need to have a semicolon on the end, like this:
--
<% Object myObject = EX.myObject; %>
--
For regular code in the jsp, you need to enclose it in <% %> and follow regular syntax rules. If your bean had a String property, you could get it this way:
--
<%=EX.myString%>
--
The <%= %> is shorthand for <% out.print( );%>.
Kinda confusing at first, but you get used to it. Hope this helps...

Re: Tomcat/JSP Question
I could be wrong, but 'int' is a primitive type, I don´t know if it extends
Object, have you tried 'Integer my_object = EX.myObject' ?

Re: Tomcat/JSP Question
Actually I was wondering if you can do this
Class Example
{
public Object myObject;
public Example()
{
this.myObject = new myObject();
} // end constructor
}
then acess it via my JSP
<% int my_object = EX.myObject %>
It says that this doesnt exist? Is there no way
to do this?
Thanks so much for your help!
Mike

RE: Tomcat/JSP Question
I think you may have the syntax for jsp:get_property jsp:set_property wrong. It is jsp:getProperty() and jsp:setProperty() Here is a textbook example from Fields and Kolbs book. Hope it helps #JSP <% page import = "com.taglib.wdjsp.components.CompoundIntrestBean" %> Hope that helps, Scott -Original Message- From: Mike Alba [mailto:[EMAIL PROTECTED]] Sent: Friday, June 01, 2001 2:47 PM To: [EMAIL PROTECTED] Subject: Tomcat/JSP Question Hi, Forgive me for the beginner question but I am trying to instantiate a class for a JSP.
