Importing Java Class inside JSP file

Question

How to import Java class inside JSP file? <%@page import="javaname.java"%> is not working in Eclipse Neon. Already defined full path still not working.

We have an existing project that the java class is inside of WEB-INF/classes instead of src folder but when we try to do it on another project, we cannot import anymore using the same syntax (<%@ page import="package.javaclass"%>)

Java class:

JSP:

@ElliottFrisch I already replaced into packagename.nameofclass still an error "the import cannot be resolved". — Marilou Maala, Dec 14 '16 at 05:35
Do you have automatic builds enabled? Did the JSP revalidate after you saved it? What's the exact error message? — nitind, Dec 14 '16 at 09:57
@nitind Yes, the automatic build is enabled. JSP does revalidate after saving. The exact error is "The Import cannot be resolved". — Marilou Maala, Dec 15 '16 at 00:28

Maybe it should be:

<%@page import="package.nameOfTheYouClass"%>

You don't need to add the .java ending to the class name.

I already did that but still an error "the import cannot be resolved". – Marilou Maala Dec 14 '16 at 05:34
Have you checked the path to your class? Can you show your class? – Nurjan Dec 14 '16 at 05:35
Uploaded screenshot for your request. – Marilou Maala Dec 14 '16 at 06:10
@MarilouMaala Do you use templates? Is your otp.jsp included in some template? – Nurjan Dec 14 '16 at 06:23
No. We didn't use any template. – Marilou Maala Dec 14 '16 at 06:36

The Totp.java source file doesn't belong in the WEB-INF/classes folder, it belongs in the fa folder under src so that Eclipse will compile it for you. At runtime the server is supposed to find the compiled Totp.class file there. I'm guessing that Totp.java is not actually in the source folder, meaning this was a correct error message all along.

If you've been adding files to, and directly editing files in, the WEB-INF/classes folder, you're doing it wrong. That folder is only ever supposed to hold classes compiled from the source folders like src and other resources copied there, by Eclipse, from the source folders.

I know that the java file should be in the scr folder. But when I placed the java file together with the wsdl files inside the src folder, it seems like they didn't connect to each other. So I decided to move it – Marilou Maala Dec 15 '16 at 01:10
Try putting it back to get past this problem, then open a separate question about that *original* one. – nitind Dec 15 '16 at 05:06

When you say "java class", do you mean an actual compiled `.class` file this time? – nitind Jan 04 '17 at 06:20
Yes is the answer to your inquiry – Marilou Maala Jan 05 '17 at 07:44
That should probably go into a Class Folder (like a Source Folder, but for .class files), since the WEB-INF/classes folder is only used for final deployment, its contents ignored during development and validation. – nitind Jan 05 '17 at 08:17

check if the name of your class is right and that's it.
