These steps can really help you:
If you didn't install any server you have to do these steps:
Menu Window ? Preferences ? Expend Server ? Runtime environment ? Add ? choose a name and then choose the Apache server path that you already installed on your PC (you can press download and install too) ? Finish ? OK
Ref# for more information, click here
Add the Tomcat server:
Project Properties ? Java Build Path ? Add Library ? Select "Server Runtime" from the list* ? Next ? Select "Apache Tomcat" ? Finish
Ref# This answer
And if nothing works by whatever reason, build it from the command line:
ant -Dj2ee.server.home=D:\apache-tomcat-8.0.23 clean
ant -Dj2ee.server.home=D:\apache-tomcat-8.0.23 compile
ant -Dj2ee.server.home=D:\apache-tomcat-8.0.23 dist
Project Properties -> Java Build Path -> in the libraries Select "Classpath" -> Add Library -> Select "Server Runtime" from the list -> Next -> Select "Apache Tomcat" -> Finish
Just add these dependencies to your pom.xml
file:
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.0.1</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>javax.servlet.jsp</groupId>
<artifactId>javax.servlet.jsp-api</artifactId>
<version>2.2.1</version>
<scope>provided</scope>
</dependency>
As this is unanswered, I am guessing something other than Maven dependencies are wrong with the ops build.
While not using Maven, I have the same problem from time to time when re-creating my development environment from svn, and I always forget why and have to figure it out. Unfortunately it seems this is a problem with Eclipse.
I am able to remove all such errors from once working projects by picking just one of the dynamic web projects, or just tomcat dependent projects, and move a dependency in the build order. This seems to force all projects to rebuild properly and all of the errors are then resolved.
Right click on a web project, select "build Path" -> "Configure Build Path". Go to the tab "Order and Export", then pick a library or jar entry and move it up or down. I used the JRE System Library and moved it to the top.
Click OK, and all that red goes away!
Try This - Add Tomcat at run time
Adding below dependency in pom.xml, worked for me.
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
</dependency>
Include servlet-api-3.1.jar
in your dependencies.
Maven
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.1.0</version>
<scope>provided</scope>
</dependency>
Gradle
configurations {
provided
}
sourceSets {
main { compileClasspath += configurations.provided }
}
dependencies {
provided 'javax.servlet:javax.servlet-api:3.1.0'
}
add servlet-api jar file which is present in the lib folder under tomcat folder. You can do this as follows Project -> properties -> java build path -> under libraries click add external jars after that go to project -> clean -> build all. this worked for me.
I faced the same error. Adding the tomcat server in the runtime environment will solve the error:
Right click on your project -> Properties -> Targeted runtimes -> Select apache tomcat server -> click apply -> click ok.
Select project ? Properties ? Project Facets ? Target Runtimes ? VMware Server.
It worked for me.
For an Ant project:
Make sure, you have servlet-api.jar in the lib folder.
For a Maven project:
Make sure, you have the dependency added in POM.xml.
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.1.0</version>
<scope>provided</scope>
</dependency>
Another way to do it is: Update the project facets to pick up the right server.
Check this box in this location:
Project ? Properties ? Target Runtimes ? Apache Tomcat (any server)
If you are not using Maven, just drop the javax.servlet-api.jar in your project lib folder.
you are getting this error because of the server is not enabled by default i.e you don't have any runtime chosen for that is why you are getting the error so, for that you need to do the following steps to choose the runtime.
Follow The Path right-click on the project --> GoTo Properties--> Click on Targeted Runtimes-->then click on the checkbox i.e Apache tomcat or other servers which you are using --->then click on apply and then apply and close
I too received the same error as quoted below:
The superclass “javax.servlet.http.HttpServlet” was not found on the Java Build Path.
I followed these steps to resolve the issue:
Add servlet-api.jar file which is present in the lib folder under tomcat folder. You can do this using the following steps:
1.Select project properties
2.Select Java Build Path
3.Select Libraries
4.Select External Jars
5.Select servlet-api.jar
6. Apply & Ok.
The issue should be resolved after these steps.
I came across the same issue. I tried adding the server in "Server Runtime" but unfortunately that didn't work for me.
What worked for me is, I added javax.servlet-api-3.0.1.jar
file in build path. On the other hand If It's a Maven project add dependency for this jar file. This would definitely work.
for maven project , you should add this dependency
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-web-api</artifactId>
<version>6.0</version>
<scope>provided</scope>
</dependency>
Adding the Tomcat server in the server runtime will do the job:
Project Properties ? Target Runtimes ? Select your Server from the list, "JBoss Runtime" ? Finish
In case of Apache you can select Apache Runtime.
Always check if your java files are in src/main/java and not on some other directory path.
Project ? Properties ? Target Runtimes ? Apache Tomcat worked for me. There is no Target Runtimes under Facets (I'm on Eclipse v4.2 (Juno)).
Adding the Tomcat server in the server runtime will do the job:
Right click your project and than;
Project properties ? Target Runtimes ? Select/Check "Apache Tomcat" ? Finish.
For an Ant project:
Make sure, you have servlet-api.jar in the lib
folder.
For a Maven project:
Make sure, you have the dependency added in POM.xml
.
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.1.0</version>
<scope>provided</scope>
</dependency>
Another way to do it is: Update the project facets to pick up the right server.
Check this box in this location:
Project ? Properties ? Target Runtimes ? Apache Tomcat (any server)
Your system can have many different tomcat versions. You can try to solve it.
Right Click on Project then Select Properties, Select Project Facets and on the right section, Select right Apache Tomcat versions as Runtimes and click ok
Project ? Properties ? Target Runtimes ? *Apache Tomcat worked for me. There is no Target Runtimes under Facets (I'm on Eclipse v4.4 (Luna)).
Add a runtime first and select project properties. Then check the server name from the 'Runtimes' tab as shown in the image.
The superclass “javax.servlet.http.HttpServlet” was not found on the Java Build Path
Error: "Can not find the tag library descriptor for "http://java.sun.com/jsp/jstl/core"
Solution: Adding the tomcat server in the server runtime will do the job : Project Properties-> Java Build Path-> Add Library -> Select "Server Runtime" from the list-> Next->Select "Apache Tomcat"-> Finish
This solution work for me.
In case of JBoss... right click on project ? Build Java path ? add external JAR files.
Then browse to jboss-folder ? Common ? lib ? servlet-api.jar
. . Click OK, refresh the project, and run it...
Adding the Tomcat server in the server runtime will do the job:
Project properties ? Java Build Path ? Add Library ? Select "Server Runtime" from the list ? Next ? Select "Apache Tomcat" ? Finish.
I had this same issue and a couple others being reported for a existing maven project.
I had the proper dependencies in place and I could see the jar under maven dependencies, however the project was improperly brought into eclipse.
I ended up having to delete the project, clone from git again then do an import of the project as an existing maven project.
This solved the issue in this thread and several others issues I was having. More details on solution can be found here: Maven Project in Eclipse `org.springframework cannot be resolved to a type` from target path
