Answer 1

i resolved the problem by using the version 7.0.0pre2 of jetty-maven-plugin and jsp-2.1 as follow :

<properties>
        <jetty.version>7.0.0pre2</jetty.version>
</properties>


<dependencies>
    <dependency>
        <groupId>org.mortbay.jetty</groupId>
        <artifactId>jsp-2.1</artifactId>
        <version>${jetty.version}</version>
    </dependency>     
</dependencies>

<build>
    <finalName>${project.artifactId}</finalName>
    <plugins>
        <plugin>
            <groupId>org.mortbay.jetty</groupId>
            <artifactId>maven-jetty-plugin</artifactId>
            <version>${jetty.version}</version>
