Webservices / XML / DTD

Hi All,

Apologies , if this is the wrong thread , But i am pretty desperate to get started. kindly help

I have a fairly good knowledge of Java Programming. Now one of my projects demands for me to know about web services , DTD , XML parsing. Please suggest me good books for the same.

And most of the books reviewed here are published atleast 2 years back. Please tell me any book that has been updated recently.

I need to study about the following.

1. Creating and Calling Web services.( I have 2 weeks , so i would like a comprehensive study guide , Including SOA , Enterprise Architecture etc )
2. Parsing XML using SAX parser ( i have worked on DOM parser , but i find SAX parser has been implemented in Many ways)
3. Enterprise Architecture in general
4. Websphere Application Server . ( i already have Pro (IBM) WebSphere Application Server 7 ) is this book sufficient

Please help me find some resources.

Thanks
