The problem is that the empty string is not a valid value for xs:dateTime. It is well and fine that you make the element nillable, but if you want the value to be nil, you need
<lastModified xsi:nil="true" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/> not just <lastModified/> or <lastModified></lastModified> As for references, I like the book, "Definitive XML Schema" by Priscilla Walmsley. For checking the lexical representations (formats) for the various date/time types, you could simply look at the spec itself, it is quite understandable. I don't have any recommendations for on-line tutorials, but you could look at http://www.w3schools.com/schema/default.asp. -----Original Message----- From: Steven Crosley [mailto:[EMAIL PROTECTED] Sent: Friday, October 19, 2007 1:11 PM To: [email protected] Subject: Re: DateTime objects Thanks. When the element is empty I get an error, but I set the element nillable=true: <xs:element name="lastModified" type="xs:dateTime" nillable="true"/> Here's the error: at java.lang.Thread.run(Thread.java:613) Caused by: javax.servlet.ServletException: javax.servlet.jsp.JspException: An error occurred while evaluating custom action attribute "value" with value "${book.lastModified}": An error occurred while getting property "lastModified" from an instance of class org.test.testing.impl.BookImpl (org.apache.xmlbeans.impl.values.XmlValueOutOfRangeException: Invalid date value: wrong type: ) at org.apache.jasper.runtime.PageContextImpl.doHandlePageException (PageContextImpl.java:846) at org.apache.jasper.runtime.PageContextImpl.handlePageException (PageContextImpl.java:779) at org.apache.jsp.WEB_002dINF.jsp.booksView_jsp._jspService (booksView_jsp.java:100) at org.apache.jasper.runtime.HttpJspBase.service (HttpJspBase.java:70) at javax.servlet.http.HttpServlet.service(HttpServlet.java:803) at org.apache.jasper.servlet.JspServletWrapper.service (JspServletWrapper.java:393) ... 121 more Caused by: org.apache.xmlbeans.impl.values.XmlValueOutOfRangeException: Invalid date value: wrong type: at org.apache.xmlbeans.impl.values.XmlObjectBase $ValueOutOfRangeValidationContext.invalid(XmlObjectBase.java:285) If you have any good links to web tutorials, I'd appreciate it. Also, is it pretty common practice to modify the model objects that get created from the xsd schema in order to handle error checking and any other data manipulation necessary or can this all be managed from the .xsd file?
