JSP strange problem

Hi,
as I've already introduces before, I try to call a jar file thru jsp page.
The problem is that I can't invoke a method in my class that in the jar.
I get this error:

org.apache.jasper.JasperException: Unable to compile class for JSP:
An error occurred at line: 14 in the jsp file: /test.jsp
hasp_demo cannot be resolved

11: </head>
12: <body>
13:
14: <%=hasp_demo.CheckFlow() %>
15: </body>
16: </html>

If someone could give me a hint... thanks.

Moving to JSP.

A JSP is translated into a servlet. Just as you can't call random code in a servlet, you can't call random code in a JSP.

Not that you should be using Java code like this in JSPs anyway.

Please read this. How can we help you if you don't give us any info to go on?

How is hasp_demo declared?

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.

The first thing I'd look at is the first error.

Well, *really* the first thing I'd look at is your package naming convention, but that, at least, won't cause an error.

Hi, Moshi.

after copying it from the place that I creates it to the HaspWeb\WebContent\WEB-INF\lib folder

Here 'HashWeb' is your application context. 'WEB-INF' must be directly inside 'HashWeb'.

Do you mean that you have a common class package, and you would like to import it into JSP file, or you've just needs to produce a java file only for the project, which means , you just needs to put your .class file into WEB-INF/classes.

So, it would be good to state your problem more clearly.
