Hi,
so here is the all data (I'm using Eclipse) :

1. I developed a class with a static method. The method is called "CheckFlow()" and returns String.
That class is using another jar files and dlls, that located inside the same project.
I put that class in a new package called "Hasp" (not in the default package), made it public class, and
gave it a name begining with Capital letter - HaspDemo.

2. I generated out of the project that contains that class a jar, called hasp.jar.

3. I created a new web project called HaspWeb. I creates a jsp file in it: test.jsp.

4. In the web project's properties , in the "Java build path" window I added to the class path the hasp.jar - the jar that I created,
after copying it from the place that I creates it to the HaspWeb\WebContent\WEB-INF\lib folder. I added it to the class path from
this location.

5. In my jsp file this is my very simple code: (I remind you that CheckFlow() is a static method):

<%@page import="Hasp.HaspDemo"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<%= Hasp.HaspDemo.CheckFlow() %>
</body>
</html>

6. I'm getting the exception of:

org.apache.jasper.JasperException: Unable to compile class for JSP:

An error occurred at line: 6 in the generated java file
Only a type can be imported. Hasp.HaspDemo resolves to a package

An error occurred at line: 13 in the jsp file: /test.jsp
Hasp.HaspDemo cannot be resolved to a type
10: <title>Insert title here</title>
11: </head>
12: <body>
13: <%= Hasp.HaspDemo.CheckFlow() %>
14: </body>
15: </html>

7. Thanks for any help.

Are the DLLs somewhere that Tomcat can find them? Are you sure that
the contents of the jar file are laid out properly? Does the JSP
Editor show any error messages?
