I have implmented a server backend for a mobile client using Spring MVC,Restful webservices. I want to secure the app with spring security. I have put a custom login.jsp to handle the login as follows.

<body onload='document.f.j_username.focus();'>
<h3>Login with Username and Password (Custom Page)</h3>

<c:if test="${not empty error}">
    <div class="errorblock">
        Your login attempt was not successful, try again.<br /> Caused :
        ${sessionScope["SPRING_SECURITY_LAST_EXCEPTION"].message}
    </div>
</c:if>

<form name='f' action="<c:url value='j_spring_security_check' />"
    method='POST'>

    <table>
        <tr>
            <td>User:</td>
            <td><input type='text' name='j_username' value=''>
            </td>
        </tr>
        <tr>
            <td>Password:</td>
            <td><input type='password' name='j_password' />
            </td>
        </tr>
        <tr>
            <td colspan='2'><input name="submit" type="submit"
                value="submit" />
            </td>
        </tr>
        <tr>
            <td colspan='2'><input name="reset" type="reset" />
            </td>
        </tr>
    </table>

</form>

my web.xml is as follows.

<display-name>Spring MVC Application</display-name>

<!-- Spring MVC -->
<servlet>
    <servlet-name>mvc-dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

</filter>

<filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

spring-security-context.xml is as follws.

<beans:beans xmlns="http://www.springframework.org/schema/security"

    <logout logout-success-url="/logout" />
</http>

<authentication-manager>
    <authentication-provider>

            <user name="admin" password="admin" authorities="ROLE_USER" />
        </user-service>
    </authentication-provider>
</authentication-manager>

But I get a warning on eclipse

The tag handler class for “c:if” (org.apache.taglibs.standard.tag.rt.core.IfTag) was not found on the Java Build Path

And get a not found error on j_spring_security_check when I submit the form. I have included jstl1.2 in the classpath. Why do I get a tag handler not found warning even if I have included the taglib?

    Why do I get a tag handler not found warning even if I have included the taglib?
    The jars in an Eclipse Dynamic Web Project that should be deployed to the server must be located in the \myProject\WebContent\WEB-INF\libs (not in \myProject\webapp\WEB-INF\lib)

    In a Eclipse Dynamic Web Project the jars in this folder will be automaticly attached to your build path, you must not add them manually.

    And get a not found error on j_spring_security_check when I submit the form:

    Check that you have the login page mapped to the url /login you can test it simply by enter the url in your broswer

    Additional hint

    One other thing that is may not so optimal is this statement

    <form name='f' action="<c:url value='j_spring_security_check' />"
   method='POST'>

    Try to write it in this way:

    <c:url value='j_spring_security_check' var='loginUrl'/>
<form name='f' action="${loginUrl}" method='POST'>

    This avoid this nasty weaving of the two tags. Maybe the problem is just that the eclipse editor is a bit confused.

    The Java Build Path should look like the image at the end of course you will have some more libs
