Throwing Exceptions _Through_ jsp:setProperty

Question

Is it possible to have a setXxxxx method explicitly throw an exception and have it caught by an isErrorPage using the <jsp:setProperty/> tag?
I'm trying to do this:
In mypage.jsp
<%@ page errorPage="myerr.jsp" %>
<jsp:useBean id="myBean" class="MyBean" ... />
<jsp:setProperty name="myBean" property="name" value="value"/>
In MyBean.java
public void setName(String name) throws MyException
throw new MyException("Something went wrong");
In myerr.jsp
<%@ page isErrorPage="true" %>
<% exception.printStackTrace(new PrintWriter(out)); %>
If I run this, it reports an org.apache.jasper.JasperException with a null message on the line number of the setProperty tag.
If I change jsp:setProperty to <% myBean.setName("value"); %> then the MyException is reported with the right message.
Any thoughts? I'm running jakarta-tomcat-3.2.1 under i386 Solaris.

You should use Java code like:
MyException ex=new MyException("Error!");
request.setAttribute ( PageContext.EXCEPTION, ex );Can it be done without having to pass the Bean the
request object?
I'd like it to work transparently through
<jsp:setProperty/> without the page coder having to do
anything extra.You should create your own bean and access to it using
<jsp:setProperty scope="request">
place code in your bean...
