form based authentication example

[cyril vidal]

Hi,
I'm under Tomcat/4.1.18-LE-jdk14 and just have tested form based example provided with the distribution.
When I access http://localhost:8080/examples/jsp/security/protected/index.jsp
i'm well redirected to login.jsp as mentionned in web.xml
<form-login-config>
<form-login-page>/jsp/security/protected/login.jsp</form-login-page>
<form-error-page>/jsp/security/protected/error.jsp</form-error-page>
</form-login-config>

but unfortunately, I've got the following error message:
Generated servlet error:
[javac] Compiling 1 source file
C:\java\plateforme\tomcat\work\Standalone\localhost\examples\jsp\security\protected\login_jsp.java:1: expected
package org.apache.jsp.jsp.security.protected;
^
1 error
I've changed nothing to example's directory, so is it an known error?
How may i fix this?
Thanks in advance for your response,
Regards,
Cyril.

Where did u place your login.jsp and error.jsp? I mean in which folder of the web application... Their locations are very important... And could you mention the web.xml that you use in the web application?
I hope I can help you, if I got more info from you...

The location of the files error.jsp and login.jsp are
<tomcat-home>\webapps\examples\jsp\security\protected (shipped with distribution)
and the code snippet of web.xml is the following:

 
 <security-constraint>
      <display-name>Example Security Constraint</display-name>
      <web-resource-collection>
         <web-resource-name>Protected Area</web-resource-name>
 <!-- Define the context-relative URL(s) to be protected -->
         <url-pattern>/jsp/security/protected/*</url-pattern>
 <!-- If you list http methods, only those methods are protected -->
 <http-method>DELETE</http-method>
         <http-method>GET</http-method>
         <http-method>POST</http-method>
 <http-method>PUT</http-method>
      </web-resource-collection>
      <auth-constraint>
         <!-- Anyone with one of the listed roles may access this area -->
         <role-name>tomcat</role-name>
 <role-name>role1</role-name>
      </auth-constraint>
    </security-constraint>
    <!-- Default login configuration uses form-based authentication -->
    <login-config>
      <auth-method>FORM</auth-method>
      <realm-name>Example Form-Based Authentication Area</realm-name>
      <form-login-config>
        <form-login-page>/jsp/security/protected/login.jsp</form-login-page>
        <form-error-page>/jsp/security/protected/error.jsp</form-error-page>
      </form-login-config>
    </login-config>
    <!-- Security roles referenced by this web application -->
    <security-role>
      <role-name>role1</role-name>
    </security-role>
    <security-role>
      <role-name>tomcat</role-name>
    </security-role>

 

Thanks,
Cyril.

I think the problem is with the classpath, coz all of the configurations are original as you downloaded and I have checked the contents already...
Is your classpath configured correctly? Verify it in command prompt by using
echo %JAVA_HOME%
It should show your installed java folder with the whole path.
and echo %CATALINA_HOME%
Verify that it shows the real tomcat installation folder
and set classpath to the servlet library too...
which is in yourTomcatFolder\common\lib\servlet.jar (or) similar...
Can u reply to me whether it works or not... It's my pleasure to solve such kind of problem... It improves my technical skill also...

Hello Pradeep,
It's nice to see you here... I think you are in IDE forum... How's your study on the beta of new SCWCD... I've just filtered the Specs with the objectives, but not yet started to study... But I will next week...
All the best for the exam to you as well...

nO. I am no where.

I've just filtered the Specs with the objectives, but not yet started to study

I would be great if you send me the filtered chapters. Thanks Sir!

Well, I do want to send you one. But what I did on the specs is that I printed out the Specs and marked on the printed papers... I don't know how I can send them to you... But I can tell you what I marked which chapters are involved in the objectives...
I'm afraid that this is not the right forum to talk about it... Let's move to the SCWCD forum...
P.S., I started one thread on SCWCD forum of JDiscuss.com already, in which it will be more specific on the objectives. If there is a chance, I hope I will see you there... But I will surely share my knowledge in SCWCD forum of JavaRanch also...
