Jason Pell commented on CXF-4597:
---------------------------------
An empty string is still a string, so minOccurs=1 would still be satisfied.
However what you could do is <xsd:minLength value="1"/>
Obviously you can't do that at the JAXB level, but at Schema level it would
certainly force you to enter at least one character for it to be considered a
legal value.
I have created an mailing list post to provide some additional input that you
may find of use.

> Hi ,
> I apologize, if I have chosen wrong issue type.
> I use contract first web service where xsd is defined in external file.
> [by default, nillable is false if we haven't mentioned for elements in xsd]
> I used jaxws-maven-plugin to import java classes from wsdl. I noticed that
> nillable attribute is missing for @XmlElement(required = true) [java data
> type string]. I assume, its the default behaviour, so Jaxb will treat those
> element as nillable false.
> But when the user sends empty tag, my web service accepts that value.
> Without touching the xsd (setting minLength for the string), is there a easy
> way to do non empty string validation?
