Subject [jira] Created: (VALIDATOR-206) NullPointerException in "ValidatorAction" class when we start application in Unix
Date Thu, 19 Oct 2006 19:30:35 GMT
NullPointerException  in "ValidatorAction" class  when we start application in Unix
-----------------------------------------------------------------------------------

                 Key: VALIDATOR-206
                 URL: http://issues.apache.org/jira/browse/VALIDATOR-206
             Project: Commons Validator
          Issue Type: Bug
          Components: Framework
    Affects Versions: 1.3.0 Release, 1.2.0 Release
         Environment: Unix
            Reporter: Anna Komaristaia


When I start the application in Unix, there is the NullPointerException going from the next
methods in  "ValidatorAction" class 

    -  loadValidationClass( ClassLoader )
    -  loadParameterClasses( ClassLoader )
    
    ClassLoadet parameter is null.

This is the printout from Unix console:

ERROR validator.ValidatorAction     - Unhandled exception thrown during validation: null
java.lang.NullPointerException
        at org.apache.commons.validator.ValidatorAction.loadValidationClass(ValidatorAction.java:623)
        at org.apache.commons.validator.ValidatorAction.executeValidationMethod(ValidatorAction.java:531)
        at org.apache.commons.validator.Field.validateForRule(Field.java:766)
        at org.apache.commons.validator.Field.validate(Field.java:846)
        at org.apache.commons.validator.Form.validate(Form.java:290)
        ...

java.lang.NullPointerException
        at org.apache.commons.validator.ValidatorAction.loadParameterClasses(ValidatorAction.java:652)
        at org.apache.commons.validator.ValidatorAction.executeValidationMethod(ValidatorAction.java:532)
        at org.apache.commons.validator.Field.validateForRule(Field.java:766)
        at org.apache.commons.validator.Field.validate(Field.java:846)
        at org.apache.commons.validator.Form.validate(Form.java:290)
        at org.apache.commons.validator.Validator.validate(Validator.java:354)
        ...


I recompiled the commons-validator jar  with the next change  and it's working fine in PC
and Unix:

            if( loader == null )
                   this.validationClass = Class.forName(this.classname);
            else
                   this.validationClass = loader.loadClass(this.classname);

Thanks,
//Anna
