Re: How to properly convert PostgreSQL timestamp to Java xsd:dateTime

PostgreSQL 9.5.4

Java 1.8

JDBC driver postgresql-9.4.1208.jar

 

Issue:

I need to map a PostgreSQL timestamp to a field in a Java bean.  The Java bean was generated using standard XSD with the element type of xsd:dateTime.  The Class type Java is assigning to this field in the Bean class is XMLGregorianCalendar.

 

Question:

I don’t know the proper way to “get” the value from the result set and the populate the Java bean.  Your assistants would be very helpful.

 

Process I have tried:

In my Java XSD I have an element defined within a complexType:

 

<xsd:element name="startTimestamp" type="xsd:dateTime" minOccurs="0" />

 

I next generate the bean.  It generates this code in Java for the above field:

 

protected XMLGregorianCalendar startTimestamp;

 

public XMLGregorianCalendar getStartTimestamp()

{

        return startTimestamp;

}

 

public void setStartTimestamp(XMLGregorianCalendar value)

{

        this.startTimestamp = value;

}

 

In PostgrSQL I have this column in table_a:

 

start_timestamp timestamp with time zone DEFAULT now(),

 

I then select the data from the database in Java:

 

String sqlStatement = “select start_timestamp from table_a”;

…

resultObject.setStartTimestamp(resultSet.getTimestamp("start_timestamp");

 

I get this error:

The method setStartTimestamp(XMLGregorianCalendar) in the type MyObject is not applicable for the arguments (Timestamp)

 

 

Thanks,
