OWSM: How to reference Custom Step properties/parameters?

Question

Hi,
When you define a Custom Step via a XML file. You can define properties/parameters. In the sample files that comes with OWSM (CustomAuthenticationStep.xml) Username and Password are defined. My problem is that I cannot figure out how to reference these in the Java Step source. In the sample file CustomAuthenticationStep.java there are no references. There are two class variables called expectedUsername and expectedUserPassword, but they are never set in the source? There are nothing in the Extensibility Guide about this. Anybody know how it works?
Regards Peter

I've made a couple of these now. It somehow walks through the xml file you upload and then the properties defined are matched with the appropriate get/set methods in the actual java code.
One example I had to make was to add HTTP Basic Auth headers to a request. Here is the section of the xml file.
<csw:PropertyDefinitionSet name="HTTP Basic Auth Params">
<csw:PropertyDefinition name="httpBasicAuthUsername" type="string" isRequired="true">
<csw:DisplayName>Username</csw:DisplayName>
<csw:Description>Http Basic Auth Username</csw:Description>
<csw:DefaultValue>
<csw:Absolute>USERNAME</csw:Absolute>
</csw:DefaultValue>
</csw:PropertyDefinition>
<csw:PropertyDefinition name="httpBasicAuthPassword" type="string" isRequired="true" displayType="password">
<csw:DisplayName>Http Basic Auth Password</csw:DisplayName>
<csw:Description>Password to access Private Key</csw:Description>
<csw:DefaultValue>
<csw:Absolute>PASSWORD</csw:Absolute>
</csw:DefaultValue>
</csw:PropertyDefinition>
</csw:PropertyDefinitionSet>
You then have these get/set methods at the bottom of the class I created.
public String gethttpBasicAuthUsername() {
return this._httpBasicAuthUsername;
public void sethttpBasicAuthUsername(String username) {
this._httpBasicAuthUsername = username;
public String gethttpBasicAuthPassword() {
return this._httpBasicAuthPassword;
public void sethttpBasicAuthPassword(String password) {
this._httpBasicAuthPassword = password;
Then I had this and the properties were available for use.
public class BasicAuthStep extends AbstractStep {
private String _httpBasicAuthUsername = null;
private String _httpBasicAuthPassword = null;
