Solution 1

you should give fully qualified name for your class. (packagename.classname) like:

    <%@ page import="pkgname.Class1"%>

Solution 2

Page directives are normally placed at the top of a JSP. Also I assume Class1 is in the default package since it does not possess a fully qualified name. If Class1 is in a package you need to prefix the name in the import with the package name.

<%@ page import="java.util.*" %>
<%@ page import="Class1" %>
<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=windows-1252"/>
</head>
<body>
    <p>
<%
Class1 tc=new Class1("test");
out.print(tc.str);
  %>
    </p>
</body>

I am trying to call a Java class from a JSP page. I have created the project using JDeveloper.

I am getting an error that says "The import cannot be resolved". I have added the Class file in WEB-INF, root folder, and tried compiling, but it still shows the same error.

Below is the code:

<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=windows-1252"/>
    </head>
    <body>
        <p>  
            <%@ page import="java.util.*"%>
            <%@ page import="Class1"%>
            <% 
                Class1 tc=new Class1("test");
                out.print(tc.str);
            %>
        </p>
    </body>
</html>

i dont think it'd really matter declaring them in the body tag

@GanGnaMStYleOverFlowErroR this was more a style or best practice suggestion.

@km yes, its a good practice, but wouldn't solve the compiler error , would it ?

@GanGnaMStYleOverFlowErroR agreed. I'm also interested in if the class is packaged. I used to work with Jdeveloper, I feel for anyone using that "tool".

@km as we can see from his JSp, that could be the only possible case.

the class is not packaged. Is packaging necessary?

Hi all, thanks for quick replies.... The class "Class1" is not packaged. If I type a different class name (class that does not exists), then JDeveloper shows error "class not found" with yellow underline. If I type correct class name, editor error is resolved, however, I get that error when I compile. I have tried adding class path of that directory, but error kept showing up. Thanks.

@user1884132 yes, you have to package your class's. its a bad practice if dont package em. check this link for more details coderanch.com/how-to/java/PackageYourBeans

I had a similar error which brought me here. I had <%@ page import="main.java.model.*" %> which resulted in CompanyDAO not being resolved when the JSP ran. I repeated the line and replaced the * with CompanyDAO like this: <%@ page import="main.java.model.CompanyDAO" %>. Much to my surprise that resolved the issue. And yes, take the time to put all your code in packages. I don't care much for "CodeRanch". I figured out packages in Eclipse by converting the mess I had made into what Eclipse wanted for a Web app.
