Trying to Use ESAPI But getting Error

问题

I am trying to use ESAPI.jar for providing security to my web application.Basically I have just started using ESAPI.jar. But problem is I am not able to run even a simple program using ESAPI. The small code snippet is:

String clean = ESAPI.encoder().canonicalize("someString");
Randomizer r=ESAPI.randomizer();    
System.out.println(r);
System.out.println(clean);

I get this error:

Attempting to load ESAPI.properties via file I/O.

I have tried copying the 3 ESAPI properties files in my source folder and also configuring them on build path but still I have not succeeded. I have tried many permutations and combinations to no avail.

Please guide me.

The content of property file is:

# User Messages
Error.creating.randomizer=Error creating randomizer

This.is.test.message=This {0} is {1} a test {2} message

# Validation Messages

# Log Messages

The ESAPI.properties file should have more than 3 lines in it. See for example:

https://web.archive.org/web/20150904064147/http://code.google.com:80/p/owasp-esapi-java/source/browse/trunk/configuration/esapi/ESAPI.properties

In my experience the ESAPI.properties file either needs to be in the same folder as the esapi.jar or needs to be compiled into the jar in a resources directory.

/resources/ESAPI.properties

I believe that either one should work. If ESAPI does not find the file it one location it looks in others.

The code for that is here around line 620:

https://web.archive.org/web/20161005210258/http://code.google.com/p/owasp-esapi-java/source/browse/trunk/src/main/java/org/owasp/esapi/reference/DefaultSecurityConfiguration.java

I just struggled through this one myself.

I created a folder called esapi in my C:/users/myname/ directory and loaded up the ESAPI.properties, validation.properties, and the ESAPI-AccessControlPolicy.xml which got me past all the not finding files errors. ESAPI looks in several places for the files. I'm running Windows 7 64 bit by the way.
Then I had to update some of the jars. I should have done this from the beginning, but I didn't know it. I was getting this error: AccessController class (org.owasp.esapi.reference.DefaultAccessController) CTOR threw exception. for every jar that needed to be a newer version, like commons collections or log4j. At the bottom of the stack trace it would reference the offending jar.

When I added the newer jars from the esapi lib directory everything just worked!

I got this message at the end in my console:

ESAPI.accessController found: org.owasp.esapi.reference.DefaultAccessController@1cb8deef

Note: There is an ESAPI_en_US.properties file, but it's the one with only a few lines in it. Just use the file in: \esapi-2.1.0-dist\src\test\resources\esapi\ESAPI.properties. That is the full complete file.

The reference SecurityConfiguration manages all the settings used by the ESAPI in a single place. In this reference implementation, resources can be put in several locations, which are searched in the following order:

1) Inside a directory set with a call to SecurityConfiguration.setResourceDirectory( "C:\temp\resources" ).

2) Inside the System.getProperty( "org.owasp.esapi.resources" ) directory. You can set this on the java command line as follows (for example):

            java -Dorg.owasp.esapi.resources="C:\temp\resources"

You may have to add this to the start-up script that starts your web server. For example, for Tomcat, in the "catalina" script that starts Tomcat, you can set the JAVA_OPTS variable to the -D string above.

3) Inside the System.getProperty( "user.home" ) + "/.esapi" directory (supported for backward compatibility) or inside the System.getProperty( "user.home" ) + "/esapi" directory.

4) The first ".esapi" or "esapi" directory on the classpath. (The former for backward compatibility.)

After having this problem and looking at the installation documentation (esapi-x.x.x-dist\documentation\esapi4java-core-x-x-install-guide.pdf) I found a very useful section which detailed that the properties file can be anywhere, provided a vm flag (-Dorg.owasp.esapi.resources=path") points to a particular directory. For example, if I stick the file in a "resources" folder at the root of my project directory, then the flag would be:

-Dorg.owasp.esapi.resources="path\to\project\root\resources"

回答5:

Can you put your file (with this name) in:

D:\Eclipse-Workspace\Test\ESAPI.properties

And show us the contents and exception again.

回答6:

Extract the esapi jar
create a folder named resources under org.owasp.esapi
copy ESAPI.properties to the org.owasp.esapi.resources
Build and deploy

回答7:

extract the jar add properties file under resources folder.

initially getting same error, after updating properties file it worked for me

回答8:

Thanks for providing the information

-Dorg.owasp.esapi.resources="path\to\project\root\resources"

This is a good source of information and has resolved my issue

回答9:

I had the same problem too. I resolved it using a little bit of James Drinkard solution. What I basically did is created a new folder with name ESAPI and added ESAPI.properties file, Validation.properties, and the ESAPI-AccessControlPolicy.xml. And archived it into a jar file and added to the lib folder under WebContet/WEB-INF and build it to the path and it worked.

*To archive it into a jar file I used windows command move ESAPI ESAPI.jar

回答10:

Look at the various scripts under 'src/examples/scripts' and they will show you one easy way to control where the ESAPI.properties files is found. (This is for ESAPI 2.0 or later.)

You will find a copy of the ESAPI.properties file will be under 'configuration/esapi'.
