I am using esapi 2.1.0 jar in our application for certain input validation.

It is working perfectly in development environment where we are using Apache Tomcat.

In SIT we have WebSphere 7 and jdk 1.6. Initially it was throwing an exception stating ESAPI.properties cannot be loaded, then I added it to the class path and now an error is being thrown: 

Caused by:java.lang.NoClassDefFoundError : org.owasp.esapi.reference.DefaultValidator(initialization failure)

The esapi 2.1.0 jar is available in classpath.

    Hi Salih ...thanks for your comments ... My doubt is that is there any version comparability issue...bcoz its working perfectly in dev env – Pavithran R Jul 20 '16 at 10:36
  • You need to provide full stack trace, as there should be some nested info why intialization is failing. – Gas Jul 20 '16 at 12:13
  • Hi Gas ... Thanks for your comments... Pls find the Stack trace : Caused by : java.lang.NoClassDefFoundError :org.owasp.reference.DefaultValidator(initialization failure) at java.lang.J9VMInternals.initialize(J9VMInternals.java:140) at java.lang.Class.forNameImpl(Native Method) at java.lang.forName(Class.java:136) at org.owasp.esapi.util.ObjFactory.make(ObjFactory.java:74) at org.owasp.esapi.ESAPI.validator(ESAPI.java:191) – Pavithran R Jul 20 '16 at 13:01
  • Where did you put that esapi jar? – Gas Jul 20 '16 at 13:29
  • In the WEB-INF/lib folder – Pavithran R Jul 20 '16 at 13:31
  • List all the jars you have in WEB-INF/lib, try to edit your post if possible instead adding comments. What JDK did you use with Tomcat? – Gas Jul 20 '16 at 15:43
  • don't forget about validation.properties. – avgvstvs Jul 22 '16 at 11:02
