i have a litte JavaEE project, and i have to secure it with the OWASP ESAPI

i integrated the ESAPI like this in Maven:

<!-- ESAPI Version 2.0.1 -->
<dependency>
    <groupId>org.owasp.esapi</groupId>
    <artifactId>esapi</artifactId>
    <version>2.0.1</version>
</dependency>

So after this i can use the ESAPI classes for programming.

i also included the .esapi folder in the server start:

 -Dorg.owasp.esapi.resources=/home/joergi/.esapi/

I also copied the ESAPI.properties and the validation.properties into

src/main/resources

(I’m not sure if it works, but i get no error while starting the server)

I looked at the ESAPI install guide (pdf) (really bad documented) and copied the example

“To test if ESAPI has been successfully integrated and configured,
create a file called EsapiIntegrationTest.java and paste in:”

 import org.owasp.esapi.ESAPI;
 public class EsapiTest {
     public static void main(String[] args){
         System.out.println("ESAPI.accessController found: " 
                                + ESAPI.accessController());
     }
 }

“If you can run this file and see the println output, then ESAPI has
been successfully installed and configured! You can now begin using
ESAPI functionality to secure your web applications!”

I “translated” it for my example:

@ManagedBean(name="testController")
@RequestScoped
public class TestController  {  

    public String esapiTest(){

    System.out.println("ESAPI.accessController found: " 
                               + ESAPI.accessController());

    return "ESAPI.accessController found: " + ESAPI.accessController();
    }
}

and i have a file test.xhtml:

<?xml version="1.0" encoding="UTF-8"?>
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
template="/WEB-INF/templates/default.xhtml">
<ui:define name="content">

    <h2>esapi test</h2>

        <h:outputText value="#{testController.esapiTest()}" />  

</ui:define>
</ui:composition>

when entering the test.xhtml i get this really long error (for a nicer few you can see it also in pastebin)

i know the ESAPI Swingset Demo – and this is running in my configuration

I have 2 questions:
is my maven and my server start configuration right?
because the error looks like the ESAPI can’t find the ESAPI Logger functions….

And
Is it even possible to use the simple test code-snippet in my setup at all?

(p.s. also tried to it without maven and just with including the downloaded jar – but its not working)

I miss something like:
(this is from the swingset demo example, NOT from my own project)

You have multiple versions of the Log4J library in your classpath, likely as a result of a downstream dependency from another library being used by your application. Examine your dependency tree to figure out where the duplicate library is being loaded and exclude it in your pom.xml

mvn dependency:tree

This will show you the dependency tree for your application.

<exclusion>
    <groupId>log4j</groupId>
    <artifactId>log4j</artifactId>
</exclusion>

Add this exclusion to the culprit dependency in your pom.xml and all should be right with the world.
