jaxws ri unmarshal exception

Question

I am using jax ws ri implementation for webservices, if in include extra < or > tag in request to my webservice, i m getting following error

S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/"> S:Server javax.xml.bind.UnmarshalException - with linked exception: [com.ctc.wstx.exc.WstxUnexpectedCharException: Unexpected character (CTRL-CHAR, code 10) in content after '<' (malformed start element?). at [row,col {unknown-source}]: [12,2]] javax.xml.bind.UnmarshalException - with linked exception: [com.ctc.wstx.exc.WstxUnexpectedCharException: Unexpected character (CTRL-CHAR, code 10) in content after '<' (malformed start element?). at [row,col {unknown-source}]: [12,2]]

*Is there any way that my webservice handles such exceptions and throw some meaningful message to my client*
