ESAPI validation is not accepting a particular regEx

i want to validate an input string with alphanumeric chars, and square brackets and hypen for example [Z01-Z02] for this i set a validation property as 

Validator.SqBrackText=^[0-9a-zA-Z \[\]\-]{1,111}$

But ESAPI.validator().getValidInput(context, input, "SqBrackText", maxLen, allowNull, true);

gives exception as in 

java.lang.IllegalArgumentException: The selected type [SqBrackText] was not set via the ESAPI validation configuration
        at org.owasp.esapi.reference.DefaultValidator.getValidInput(DefaultValidator.java:215)

obviously ESAPI is not accepting the validation property although regExTester accepts the rule. There are other validation property rules in this same file which ESAPI is OK with.

Can anyone suggest what may be wrong or missing in this.

thanks

Solution

  • Well got the solution - need to give 2 backslash to escape the []- chars.

    so used this regex and it worked OK 

      Validator.SqBrackText=^[0-9a-zA-Z \\[\\]\\-]{1,1024}$

    thx for all the help !
