Hello Paul (and all)
I tried to create an enumeration using your template below. However,
when I ran Java2WSDL, I got the following error:
...
[axis-java2wsdl] - The class com.nci.slt.epi.admin.Enumeration does not
contain a default constructor, which is a requirement for a bean class.
The class cannot be converted into an xml schema type. An xml schema
anyType will be used to define this class in the wsdl file.
...
I was under the impression that if I followed your template, that I
wouldn't need a public default constructor. Am I mistaken? Is there
something I'm missing?
Here is my implementation of the enumeration test code:
package com.nci.slt.epi.admin;
import java.util.HashMap;
import org.apache.commons.lang.builder.ToStringBuilder;
import org.apache.commons.lang.builder.EqualsBuilder;
import org.apache.commons.lang.builder.HashCodeBuilder;
public class Enumeration {
public static final int _ONE = 1;
public static final Enumeration ONE = new Enumeration( _ONE );
public static final int _TWO = 1;
public static final Enumeration TWO = new Enumeration( _ONE );
public static final int _THREE = 1;
public static final Enumeration THREE = new Enumeration( _ONE );
private static HashMap ALL = new HashMap();
static {
ALL.put( new Integer( _ONE ), ONE );
ALL.put( new Integer( _TWO ), TWO );
ALL.put( new Integer( _THREE ), THREE );
}
private int value;
protected Enumeration( int type ) {
value = type;
}
public int getType() {
return value;
}
public static Enumeration fromValue( int value ) {
return (Enumeration) ALL.get( new Integer( value ) );
}
public static Enumeration fromString( String valueStr ) {
try {
int value = Integer.parseInt( valueStr );
return fromValue( value );
} catch ( NumberFormatException e ) {
throw new IllegalArgumentException();
}
}
public String toString() {
return new ToStringBuilder( this )
.append( "type", this.getType() )
.toString();
}
public boolean equals( Object object ) {
if ( object == this ) {
return true;
}
if ( !(object instanceof Enumeration) ) {
return false;
}
Enumeration rhs = (Enumeration) object;
return new EqualsBuilder()
.appendSuper( super.equals( object ) )
.append( this.value, rhs.value )
.isEquals();
}
public int hashCode() {
return new HashCodeBuilder( -609718375, -2117186511 )
.appendSuper( super.hashCode() )
.append( this.value )
.toHashCode();
}
}
