Searching for Jabber users via Smack API?

Question

Java

I am writing an application in Java, I use this code to search for users:

UserSearchManager search = new UserSearchManager(connection);<br/>
 try {<br/>
<br/>
Form searchForm = search.getSearchForm(&quot;jabber.com&quot;);<br/>
 Form answerForm = searchForm.createAnswerForm();<br/>
 answerForm.setAnswer(&quot;last&quot;, &quot;DeMoro&quot;);<br/>
 ReportedData data = search.getSearchResults(answerForm, &quot;jabber.com&quot;);<br/>
<br/>
} catch (XMPPException xmppe) {<br/>
<br/>
Marishko.SystemLog(&quot;Error initializing search form fields: &quot; + xmppe);<br/>
<br/>
}<br/>

However, nothing happens, an error is thrown.
Perhaps someone has practical experience in this matter that you would be willing to share?
