Hi All,
I have a search user page where user can be searched by firstname and last name.

My Code

xhtml

<h:form id="searchCallCenterAgentForm" style="width:600px;">
 <f:facet name="header">Call Center Agent Search</f:facet>
 <div class="dialog"><h:panelGrid columns="2" rowClasses="prop"
 columnClasses="name,value">
 <h:outputLabel for="firstName">First Name</h:outputLabel>
 <h:inputText id="firstName"
 value="#{callCenterAgentManage.firstName}" style="width:150px"
 required="false">
 <a:support event="onkeyup" actionListener="#{callCenterAgentManage.searchCallCenterAgent}"
 reRender="searchResults" />
 </h:inputText>
 <h:outputLabel for="lastName">Last Name </h:outputLabel>
 <h:inputText id="lastName"
 value="#{callCenterAgentManage.lastName}" style="width:150px"
 required="false">
 <a:support event="onkeyup"
 actionListener="#{callCenterAgentManage.searchCallCenterAgent}"
 reRender="searchResults" />
 </h:inputText>
 </h:panelGrid></div>
 <div class="actionButtons"><a:commandButton value="Search"
 action="#{callCenterAgentManage.searchCallCenterAgent}"
 id="searchCallCenterAgent" reRender="searchResults" /></div>
 </h:form>
 </rich:panel> <rich:panel style="width:600px;">
 <a:outputPanel id="searchResults">
 <div class="section"><h:outputText value="No Agents Found"
 rendered="#{agentDetails != null and agentDetails.rowCount==0}" />
 <h:dataTable id="agentDetails" value="#{agentDetails}" var="details"
 rendered="#{agentDetails.rowCount>0}">
 <h:column>
 <f:facet name="header">User Name</f:facet>
 #{details.strUserName}
 </h:column>
 <h:column>
 <f:facet name="header">First Name</f:facet>
 #{details.person.strFirstName}
 </h:column>
 <h:column>
 <f:facet name="header">Last Name</f:facet>
 #{details.person.strLastName}
 </h:column>
 <h:column>
 <f:facet name="header">Account Status</f:facet>
 #{details.flgAccountStatus}
 </h:column>
 </h:dataTable>
 </a:outputPanel>
 </rich:panel>

 if (!firstName.equals("")) {
 searchQuery += "and lower(p.strFirstName) like #{firstNamePattern} ";
 }

 if (!lastName.equals("")) {
 searchQuery += "and lower(p.strLastName) like #{lastNamePattern} ";
 }

 searchQuery += " and a.person.ipersonId = p.ipersonId";
 agentDetails = em.createQuery(searchQuery).getResultList();
 log.info("Search query = " + searchQuery);
 log.info("Result count = " + agentDetails.size());
 }
Getters and setters

When I click search it says
Error:--

Exception during request processing:
Caused by javax.servlet.ServletException with message: "/manage.xhtml: For input string: "strUserName""

Does anyone have any idea whats going wrong?

Thanks in advance
