                       System.out.println("** Warning1"

                   // treat validation errors as fatal
                   public void error(SAXParseException spe)
                           throws SAXParseException {
                       System.out.println("** Warning2"
                           + ", line " + spe.getLineNumber()

                    // dump warnings too
                   public void warning(SAXParseException err)

                     System.out.println("   " + err.getMessage());
                   }              
           });  

    builder.build(new FileReader(xml));

但是这样检验一个不合法的xml时，报错的信息很难定位，比如：
** Warning2, line 27, uri null
   cvc-datatype-valid.1.2.1: '' is not a valid 'integer' value.
org.jdom.input.JDOMParseException: Error on line 27: cvc-datatype-valid.1.2.1: '' is not a valid 'integer' value.
 at org.jdom.input.SAXBuilder.build(SAXBuilder.java:468)

能不能在xsd中事先配置好出错时该显示的信息，比如：
<xs:annotation>a must be string</xs:annotation>
<xs:element name="a" type="xs:string"/>这样，一但验证出错则打出“a must be string”提示？

请问各位有什么好方法么？
