Bean cannot be resolved to a type [message #211635] Thu, 03 April 2008 01:51 Go to next message

After doing some learning about the Data Tools Platform stuff, I'm back
trying to write a tutorial for JSP and servlets. I have a perplexing
problem. I know there is some mystery surrounding packages with respect
to JSPs. Yet, in my project, there shouldn't be much ambiguity.

Despite seeing my bean's class file on the path
WebContent/classes/<package-path>/GreetingBean.class, Eclipse gives me
the error, "GreetingBean cannot be resolved to a type" in my JSP trying
to use it. The two lines with errors are marked below, but you can see
the very screen shot including Project Explorer at the URL following it.


<%! GreetingBean greeting = new GreetingBean(); %> *******
<h1 class="heading"> Get Greeting and Color </h1>

<form action="GreetingAndColor" method="post" enctype="text/plain">
<table>
<tr><td class="query-prompt"> Greeting: </td>
<td>
<input type="text"
name="greeting"
size="60"
value="<%= greeting.getGreeting() %>" /> *****
</td>
</tr>

I'd appreciate any pointers, cat-calls or wolf-whistling that can help
me at this point. I've cleaned the project several times, but I can't
seem to get past this problem.

Many thanks,

Russ Bateman

Hi,

it seems you are missing the package imports. Add this to your JSPs:

<%@page import="my.package.*, my.package.GreetingBean"%>

Best regards

Thanks, Wolfgang. None of the books I had consulted listed the <%@page
tag for JSP and one in particular bemoaned the fact that you couldn't
specify a package. Maybe this is a recent thing in JSP and my books are
old. None of my friends who do JSP knew the answer either.

Profuse thanks,

Russ
