now follow following steps:

1. right click on project >properties >project fact
2. check on java by selecting version on its right side with dropdownlist.
3. check on Dynamic Web Module with its version (remember that different version of this requires different version of TomcatServer so installed one step old version of tomcatServer)
4. now click apply n ok.

There are different reason for this problems but this is the most cases. is not solved contact at sanlama21@outlook.com

Answer 2

This works for me ...

file >> New >> Dynamic web project >> Enter project name >> Change 'Dynamic Web module version' from 3.0 to a lower version ,say 2.5, then change it back to 3.0 , the error message disappears . I think the initial error message that says it requires java 1.6 or above is a bug in Eclipse Java EE.

Answer 3

Most probably you have several installed java versions on your PC, and your Eclipse is started based on old version.
In command line java -version command shows default one or even first installed one, which is saved somewhere in registers, and it is not always that which is used by your applications. (As example, I have only 1.7 installed physically now but java -version shows old one 1.5)

You may try next: right click on Eclipse shortcut, chose Shortcut tab, and change Target field so that it run with -vm argument pointing on that Java version you need:
"D:\eclipse-jee-kepler-R-win32-x86_64\eclipse\eclipse.exe" -vm "C:\Program Files\Java\jdk1.7.0_45\bin\javaw.exe"

Answer 5

I needed to modify the configuration and create a new runtime for tomcat. Not sure what happened to the original installation, but creating a new one did the trick.

TomcatConfiguration

This is late answer. But may help to other. If you are using Maven based project. You just include following code in pom.xml file. It can be resolved.

<build>
    <plugins>
        <plugin>
            <artifactId>maven-compiler-plugin</artifactId>
            <configuration>
                <source>1.7</source>
                <target>1.7</target>
            </configuration>
        </plugin>
    </plugins>
</build>

Update: Similarly if you are using jdk version 1.8 just include it in your <source> and <target> tags.
