Description

When using a WSDL that has a message with an element that uses a simpleContent with a restriction base of type xsd:token, see below. The class that WSDL2JAVA generates has a constructor that accepts a Token. This is a correct generated class. However, during deserialization of the response message the SAX handler throws a Null Pointer exception as it's trying to look a constructor on that class of type String.

– Constructor that gets generated:

// Simple Types must have a String constructor
public ItemTypeCodeType(org.apache.axis.types.Token _value)

{ super(_value); }

– To Fix the issue the class created should have a constructor that accepts a String as well and generate a token from that:

// FIX because tokens are not simple...
public ItemTypeCodeType(String _value) { super(_value); }

// Constructor
protected ItemTypeCodeContentType(org.apache.axis.types.Token value)

{ _value_ = value; _table_.put(_value_,this); }

//FIX
protected ItemTypeCodeContentType(String value)

{ _value_ = new org.apache.axis.types.Token(value); _table_.put(_value_,this); }
