-------------------------------------------------------------------
Here is a possible workaround until it is fixed. For you, who like me, can't
wait for this to be solved and are stuck on xmlbeans 2.2:
Lets say that getValue is the method of the XMLObject that is supposed to give
you a Calendar but throws XmlValueOutOfRangeException instead. What I found is
that xgetValue successfully returns an XmlDateTime. Trying to do getCalendar
will throw the same exception but toString will successfully give you a String
representation which looks something like this: <xml-fragment>2012-11-01
00:00:00.0</xml-fragment>
See my example below how to solev this:
Calendar cal;
try {
cal = xmlObj.getValue();
} catch (org.apache.xmlbeans.impl.values.XmlValueOutOfRangeException ex) {
/**
* Due to a bug in xmlbeans this exception
is thrown when trying to get a date.
* See
https://issues.apache.org/jira/browse/XMLBEANS-473 This workaround reads the
xml representation
* instead and parses out the date.
*/
Date dateFromXmlString =
convertFaultyXMLDateStringToDate(xmlObject.xgetValue());
cal= Calendar.getInstance();
cal.setTime(dateFromXmlString);
}
private Date convertFaultyXMLDateStringToDate(String xmlString) throws
ParseException {
Pattern datePattern = Pattern.compile("[0-9]*-[0-9]*-[0-9]*
[0-9]*:[0-9]*:[0-9]*.[0-9]*");
Matcher dateMatcher;
dateMatcher = datePattern.matcher(xmlString);
if (dateMatcher.find()) {
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd
HH:mm:ss.S");
return sdf.parse(dateMatcher.group(0));
} else {
//Handle no match
}
}
Something to use until it's fixed.

Use this method will parse out the date from that String and return a Date:
private Date convertFaultyXMLDateStringToDate(String xmlString) throws
ParseException {
Pattern datePattern = Pattern.compile("[0-9]*-[0-9]*-[0-9]*
[0-9]*:[0-9]*:[0-9]*.[0-9]*");

dateMatcher = datePattern.matcher(xmlString);
if (dateMatcher.find()) {
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd
HH:mm:ss.S");
return sdf.parse(dateMatcher.group(0));
} else {
//Handle no match
}
}

> XML "dateTime" type issue with JDBC Control
> -------------------------------------------
>
> Key: XMLBEANS-473
> URL: https://issues.apache.org/jira/browse/XMLBEANS-473
> Project: XMLBeans
> Issue Type: Bug
> Components: XmlObject
> Affects Versions: Version 2.2
> Reporter: Sunil Polineni
> Labels: features
> Attachments: jdbcTestWorkspace.rar
>
>
> This issue happens when you define a database control method which SELECTs
> data and returns an XML Bean document. If one of the selected columns in your
> XML schema is of type "dateTime", then the XML text that is returned is
> missing the required "T" time separator character. Therefore, any subsequent
> attempts to call the getters on the resulting XML Bean document object (which
> normally should return java.util.Calendar objects) results in exceptions.
> @JdbcControl.SQL(statement="SELECT THE_ID as \"theId\", THE_DATE as
> \"theDate\" FROM JDBC_TEST WHERE THE_ID = {id}")
> XJdbcTestDocument runJdbcTest(String id) throws SQLException;
> XJdbcTestDocument is generated from the below xml file
> =========================================
> <schema
> xmlns="http://www.w3.org/2001/XMLSchema";
> targetNamespace="java:///JdbcTestXMLSchema"

> The <xml-fragment>1998-05-31 00:00:00.0</xml-fragment> is missing "T" it
> should be <xml-fragment>1998-05-31T00:00:00.0</xml-fragment> when this is
> being returned by a JDB Control and getting below exception
> javax.el.ELException:
> org.apache.xmlbeans.impl.values.XmlValueOutOfRangeException: Invalid date

> I think When JDBC Control maps result set to XML, it by default uses SQL
> object's toString() method to convert from SQL object to String.
> To override/customize this behavior we can use ResultSetMapper
> http://beehive.apache.org/docs/1.0.1/system-controls/jdbc/apidocs/javadoc/org/apache/beehive/controls/system/jdbc/ResultSetMapper.html
> but this requires some good amount change in the code.
> Can you please advise whether if there is any other alternative?
