I added the commons validator to my Struts implementation. The
out-of-the-box stuff is working just fine. However, I added the following
custom validator:
public class BarnmanValidator implements Serializable {
public static boolean validateEmailAddress(Object bean, Field field) {
[etc, etc, etc]
When this one is about to be invoked, I get this exception (as root cause of
a servlet exception):
java.lang.NoClassDefFoundError: org/apache/commons/validator/Field
at java.lang.Class.getDeclaredMethods0(Native Method)
at java.lang.Class.privateGetDeclaredMethods(Class.java:1647)
at java.lang.Class.getMethod0(Class.java:1893)
at java.lang.Class.getMethod(Class.java:976)
at
org.apache.commons.validator.Validator.validateFieldForRule(Validator.java:4
01)
the validator def:
<validator name="email.unique"
classname="com.springwell.barnman.validator.BarnmanValidator"
method="validateEmailAddress"
methodParams="java.lang.Object,org.apache.commons.validator.Field"
msg="errors.email.duplicate"
/>
the form def:
<form name="register" >
<field property="emailAddress" depends="required,email,email.unique" />
<field property="password1" depends="required" />
<field property="password2" depends="required" />
<field property="firstName" depends="required" />
<field property="lastName" depends="required" />
</form>
If I omit my custom validator everything works fine.
the commons-validator.jar is in my war file's WEB-INF/lib, and there seems
to be no problem locating org.apache.commons.validator.Validator (as you can
tell from the stacktrace). Only thing I can think of is that it's a
different classloader trying to load the Field class through reflection? Any
known solutions to known problems?
thanks in advance,
Rob
