Problem with xsd and xml validation using JAXB [message #809163]

Hi,
I am validating the xml file with xsd. I am getting a problem when there is a regular expression which contains the escape characters
For example
my xsd is like :
<xs:simpleType name="DestinationStringLimitedType">
<xs:restriction base="xs:string">
<xs:pattern value="([a-zA-Z0-9\_\.\*\%\-]){1,28}"/>
<xs:whiteSpace value="collapse"/>
</xs:restriction>
</xs:simpleType>

when i am trying to validate using jaxb i'm getting the error as

Pattern value '([a-zA-Z0-9\_\.\*\%\-]){1,28}' is not a valid regular expression. The reported error was: 'This expression is not supported in the current option setting.'

And when i remove the escape characters it is not giving any errors that is if the xsd is <xs:pattern value="([a-zA-Z0-9_.*%-]){1,28}"/> .

1) How to make JAXB work with this regular expression(with escape characters)?
2) How to configure Xerces to make it parse this regular expression?

Can any one help me with the above problem ?

Manoj,

This newsgroup is for asking questions about Eclipse's XSD model APIs,
not a general XML Schema newsgroup. More comments below.

I don't believe you need to escape characters in a character group.

I don't think you need then and I don't think they're allowed.

If the expression is valid, Xerces will like it, otherwise you'll get an
error. There's no avoiding that.
