New to Java

I have a request like this:
str = "select a.responsibleName," +
" a.responsibleInfo," +
" a.responsiblePhone," +
" a.responsiblePhoneFax," +
" a.responsibleEmail " +
" from RegistrationCardOffice a " +
" where a.user.userId = "+ code +
" group by a.responsibleName, a.responsibleEmail, a.responsiblePhone, a.responsiblePhoneFax, a.responsibleInfo";

Result of it is stored in ListDataModel();
Then I have a dataTable on page.

<h:dataTable value='#{responsible.resposibles}' var='item' border="0" cellpadding="2" cellspacing="1" width="100%" styleClass="ma">
<h:column>
<f:facet name="header">
<h:outputText value="#{bundleRegistration.responsibleName}"/>
</f:facet>
<h:outputText value="#{item.responsibleName}"/>
</h:column>
.... other fields are the same

I'm making an output of reseaved data in this datatable.
All fields are string values. I whant to make an outpun without any formating to number
I can't understand why this formating into Number actually happened.
I whanted to make an output of responsibleName in string format.
What is wrong?

Here is the log:
