struts2 spring项目在jetty和tomcat上运行

Question

I am working on a web project which I can successfully deploy on Tomcat. Now I want to run the project in jetty. I created a main method which starts jetty. jetty starts at port 8080, but showing error 500 JSP support not configured so i add jetty jsp dependency. then it throw an exception org.apache.jasper.JasperException: /common/taglibs.jsp(2,80) PWC6188: The absolute uri: http://www.springframework.org/security/tags cannot be resolved in either web.xml or the jar files deployed with this application (where taglib.jsp contains different tag-libs)

Then When I run it on tomcat it starts up with some info INFO: TLD skipped. URI: http://java.sun.com/jsp/jstl/sql is already defined INFO: TLD skipped. URI: http://java.sun.com/jsp/jstl/sql is already defined

and when I start it gives java.lang.NoSuchMethodError: org.apache.jasper.runtime.PageContextImpl.proprietaryEvaluate(Ljava/lang/String;Ljava/lang/Class;Ljavax/servlet/jsp/PageContext;Lorg/apache/jasper/runtime/ProtectedFunctionMapper;Z)Ljava/lang/Object;

maven dependency

<dependency>
    <groupId>org.eclipse.jetty</groupId>
    <artifactId>jetty-server</artifactId>
    <version>${jetty.version}</version>
</dependency>
<dependency>
    <groupId>org.eclipse.jetty</groupId>
    <artifactId>jetty-webapp</artifactId>
    <version>${jetty.version}</version>
</dependency>
<dependency>
    <groupId>org.eclipse.jetty</groupId>
    <artifactId>jetty-jsp</artifactId>
    <version>${jettyjsp.version}</version>
</dependency>

EDIT 1: when I add <scope>provided</scope> to the dependency tomcat starts successfully but when starting jetty it still gives the following stack trace

org.apache.jasper.JasperException: /common/taglibs.jsp(2,80) PWC6188: The absolute uri: http://www.springframework.org/security/tags cannot be resolved in either web.xml or the jar files deployed with this application

Answer 1

You are facing different problems.

Jetty concerns

You must NOT declare jetty as a dependency, but as a plugin, if you really want to run it as a server.

Jetty would work just adding these lines to your pom.xml :

Recent version of plugin

<build>
    <!-- MORE CONF HERE -->
    <plugins>
        <plugin>
            <groupId>org.eclipse.jetty</groupId>
            <artifactId>jetty-maven-plugin</artifactId>
            <version>9.0.0.v20130308</version>
        </plugin>

        <!-- Maybe more plugins here -->
    </plugins>
    <!-- EVEN MORE Build CONF HERE -->
</build>

Or older versions (like in my projects)

<plugin>
    <groupId>org.mortbay.jetty</groupId>
    <artifactId>jetty-maven-plugin</artifactId>
    <version>8.1.3.v20120416</version>
</plugin>

They are many available plugin configurations, but the basic one is sufficient.

More info :

• maven jetty - org.mortbay.jetty vs org.eclipse.jetty

Servlet API issues

Your java.lang.NoSuchMethodError means that you are trying to run your app, with an embedded Servlet API in a version, say version A, against a server running it in another one, say version B. These versions are incompatible.

You should declare Servlet API only as provided, not the default scope (compile), and make sure that your server support it.
