JAXB assistance needed (runtime error)

Question

The code will compile fine however i keep getting errors when i try to compile the generated classes based on the schema. At runtime I get a runtime exception of NoClassFoundException since the files are not compiling. I have moved the JAXP files over to my JAVA_HOME\lib and lib\endorsed directory per all the instructions that I can find however when I try to compile the classes of the below schema I get 25Errrors during compilation of the generated.impl package and about 36 errors durning the generated.impl.runtime package. Can anyone help explain to me where i'm going wrong?
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="item">
<xs:complexType>
<xs:sequence>
<xs:element name="name" type="xs:string"/>
<xs:element name="priority" type="xs:int"/>
<xs:element name="task" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
I think i have my classpath wrong for the JAXP files but i'm not sure. I have the classpath pointing to the lib\jaxp-api.jar as well as the files located in lib\endorsed.

Upon looking at the errors more closely the majority of them spawn from the absense of the javax.xml.XMLConstants class. I see that this is part of the wsdk 1.2 classes however does anyone know which jar file has this in it?
