Problems with jsp:setProperty & introspection

[Richard Wooding <ri...@camara.co.za>]

Hi,

I am having trouble with jsp:setProperty

I have a bean CategoryBean which has the property CategoryNo
the bean has a setCategoryNo and a getCategoryNo and it adheres to the
JavaBean spec.

When I use the following code in jsp:

<jsp:useBean id="category" class="za.co.camara.fedhasa.CategoryBean"
scope="request">
<jsp:setProperty name="category" property="*" />
</jsp:useBean>

it fails to set any of the parameters I pass to it:

<jsp:useBean id="category" class="za.co.camara.fedhasa.CategoryBean"
scope="request">
<jsp:setProperty name="category" property="CategoryNo">
</jsp:useBean>

it generates the following exception:

Error: 500
Location:/fedhasa/category.jsp
Internal Servlet Error:

org.apache.jasper.JasperException: Cannot find any information on property
'CategoryNo' in a bean of type 'za.co.camara.fedhasa.CategoryBean'

 at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:119)
 at javax.servlet.http.HttpServlet.service(HttpServlet.java:853)
......... etc.

This failure to successfully introspect properties is happening with all  my
beans.
What could be causing this???

Try it with the property renamed to use a lower case 
initial letter.
