How do I import the javax.servlet API in my Eclipse project?
When I try to use javax.servlet.http.*; an error package does not exist is thrown. Should I want to reinstall java or it occurs due to some other problem. I'm using j2sdk 1.4.0 & Tomcat 6.0.
Guess servlet.jar is not on the classpath. Assuming you are on Windows, right click on My Computer -> Properties -> Advanced -> Environment Variables, and check your CLASSPATH entry.

Tomcat 7 and JSTL
(9 answers)
Closed 1 year ago.
I imported a project from Github into myElcipse (latest version) and I'm using Tomcat 9.0 version for deployment. The project itself was looking for the Tomcat v 7.0, which wasn't in my system so I switched it to v 9.0 and it worked. But after that, I received the following problem :
Can not find the tag library descriptor for "http://java.sun.com/jsp/jstl/core"
My directory looks somewhat like this
And these are what the errors look like.
Now, I saw that you need to have the jstl files in your WEB-INF**->**lib folder. But there was no lib folder within my WEB-INF. Atleast, not according to this project. Can anyone tell me what changes I should make in order to rectify this error?
Here's a sample code snippet that contains one of these errors.

I think I am not alone who doesn't know how to properly download Java and JavaFX on Linux. And how make it works in IntelliJ Idea
So my questions are:
I'm looking for Java JRE or Java SDK?
Must Java and JavaFX be at same version?
How I will connect it with IntelliJ
Do I have to write something like in windows "path variable"?
Maybe this is not proper question, because it was answered somewhere else, but I dont undrestand basic things about installation of Java. Thanks everyone.
1) JRE is a Java Runtime Environment - enough for Java code to run but not enough to develop code. What you need is JDK (Java Development Kit), you can download it here https://www.oracle.com/technetwork/java/javase/downloads/index.html
2) No, they don't need to be the same version
3) Follow these steps: https://openjfx.io/openjfx-docs/#maven
I prefer doing it with Maven (less hassle) but you can find easy to follow explanations for both on that page
4)Yes in linux you need to add Path variable as well - here are the instructions:

Project Structure-->SDK location shows /Library/Java/JavaVirtualMachines/jdk1.7.0_71.jdk/Contents/Home
the project structure view shows jdk 1.7. I see java.nio.file when I expand the packages, but
import java.nio.file can't be found even after rebuilding. java.io.Reader is found by the editor.
I'm not entirely sure, but I think this has something to do with the android sdk not allowing this. I have the sdk and the jdk listed in Project view-->"External Libraries"

Access restriction on class due to restriction on required library rt.jar?

Closed 9 years ago.
I'm writing a Java app and am currently working on all of the Apple native LAF stuff. I'm trying to customize the application menu and I've found that I need to use com.apple.eawt.Application in order to do so. However, when I try to import that class, my IDE says:
Access restriction: The type Application is not accessible due to restriction on required library /Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Home/jre/lib/rt.jar
I'm using JDK 1.7 update 45, on Mac OS X 10.9, using Eclipse. The rt.jar is on the classpath, but something is unhappy. How do I resolve this?
you might be trying it with JRE in your build path, you can try changing it to JDK
please refer my answer
