Hi Thanks, for your reply. I think I have got me wrong. That linked document tells me how to use it. But My Query is not exactly that one. We need validator-rules.xml and validation.xml. Anyhow we have option to change the name also. Again I can specify different validation.xml like validation1.xml,validation2.xml,...validationN.xml. And we need to give the entry in struts-config.xml with coma separated. My query if I can break validation-rules.xml into multiple files? If we can do it than for a big application we can split our all validator-rules to make it more maintainable.
