I\'m having a weird configuration problem with Maven in Eclipse. Although I can build the project and deploy it to tomcat without any errors, The Marker tab keeps showing th

Answer 1

I had the same problem. After adding velocity dependencies in my maven project i was getting the same error in marker tab. Then I noticed that the web.xml file that maven project creates has servlet2.3 schema. When i changed it to servlet 3.0 schema and save the project then this error gone. Here is the web.xml file that maven creates

<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
    <display-name>Archetype Created Web Application</display-name>
</web-app>

Change it to

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
                        http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
                        version="3.0">
    <display-name>Archetype Created Web Application</display-name>

</web-app>

save the project, and your error would gone.

I have encountered this with Maven projects too. This is what I had to do to get around the problem:

First update your web.xml

<web-app xmlns="http://java.sun.com/xml/ns/javaee" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
                    http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
                    version="3.0">
<display-name>Servlet 3.0 Web Application</display-name>

Then right click on your project and select Properties -> Project Facets In there you will see the version of your Dynamic Web Module. This needs to change from version 2.3 or whatever to version 2.5 or above (I chose 3.0).

However to do this I had to uncheck the tick box for Dynamic Web Module -> Apply, then do a Maven Update on the project. Go back into the Project Facets window and it should already match your web.xml configuration - 3.0 in my case. You should be able to change it if not.

If this does not work for you then try right-clicking on the Dynamic Web Module Facet and select change version (and ensure it is not locked).

Or you can follow this steps:

1. Window > Show View > Other > General > navigator
2. There is a .settings folder under your project directory
3. Change the dynamic web module version in this line to 3.0
4. Change the Java version in this line to 1.5 or higher

don't forget to update your project

Hope that works!

I had a similar problem. I was working on a project where I did not control the web.xml configuration file, so I could not use the changes suggested about altering the version. Of course the project was not using JSF so this was especially annoying for me.

I found that there is a really simple fix. Go to Preferences > Maven > Java EE Itegration and uncheck the "JSF Configurator" box.

I did this in a fresh workspace before importing the project again, but it may work equally as well on an existing project ... not sure.

Answer 4

I too had the same problem.

The solution for me was to add following in the pom.xml as suggested here.

<build>
    <plugins>
        <plugin>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>2.0.2</version>
            <configuration>
                <source>1.7</source>
                <target>1.7</target>
            </configuration>
        </plugin>
    </plugins>
</build>

Answer 5

You should check your project facets in the project configuration. This is where you may uncheck the JSF dependency.

Answer 6

The below steps should be the simple fix to your problem

1. Project->Properties->ProjectFacet-->Uncheck jsf apply and OK.
2. Project->Maven->UpdateProject-->This will solve the issue.

Here while on Updating Project Maven will automatically chooses the Dynamic web module
