出现错误 java.lang.ClassNotFoundException: javax.servlet.jsp.jstl.core.Config

Question

I am developing a spring boot project. The code works perfectly fine on localhost in intelliJ.

The war file was created using command

mvn clean install

But when I run it on centos server with command

java -jar app.war

On running above command the deploy is successfully started at port 8080

But the problem occurs when any page containing jstl jsp is access. It displays 404 error following error is visible on log. This code was working perfectly fine few days ago but now I cant get what changed except I made few code changes and deployed the new war file. I haven't changed anything in pom.xml.

I tried both the ways w/ and w/o provided

Answer 1

I think the problem here is that you are using the "provided" scope for your servlet. The provided scope means it will be used for build and testing but not for runtime, as it will be provided by the runtime environment (container, specific server..). You should remove the scope if you want to run it with cli.

Answer 2

It is not possible to run a war file outside of a container.Remove war from POM this will set packaging to default(jar). Then use below command in CentOS to run the project.

1. java -jar app.jar

The other solution is to install a container in CentOS and then deploy the War to it.
