I am using JSF,Spring and Hibernate.
I would like to catch this exception and throw it in the JSF UI near partner code field as a message.
Is this possible to do.
My JSF:
<tr>
<td width="30%" align="right" ><b><h:outputText id="pPartnerCode" value="Partner Code" /></b><span style="color:red">*</span></td>
<td width="60%">:
<h:inputText id="partnerCode" value="#{partnerMast.partnerCode}" required="true">     
<t:validateRegExpr pattern="^[a-z||A-Z||0-9||_||\s||/]+$" />
<f:validateLength minimum="1" maximum="3" />     
</h:inputText>          
<h:message for="partnerCode" showDetail="true" style="color:red" /></td>
</tr>
<tr>
<td width="40%" align="right"><b><h:outputText id="pPartnerName" value="Partner Name" /><span style="color:red">*</span></b></td>
<td width="60%" align="left">:               
<h:inputText id="partnerName" value="#{partnerMast.partnerName}" required="true" >     
<t:validateRegExpr pattern="^[a-z||A-Z||0-9||_||\s||/]+$" />
<f:validateLength minimum="1" maximum="50"/>     
</h:inputText>
<h:message for="partnerName" showDetail="true" style="color:red" />
</td>
</tr>
<h:commandButton id="addUser" value="Save" action="#{partnerMastCtrl.addAction}" styleClass="style10"/>
My controller:
public String addAction()
try
partnerMast = (PartnerMast)context.getExternalContext().getSessionMap().get("partnerMast");
partnerHostingMast = (PartnerHostingMast) context.getExternalContext().getSessionMap().get("partnerHostingMast");
this.getService();
if(partnerHostingMast != null && partnerHostingMast.getHostingPartner() != null && partnerMast.getPartnerType().equalsIgnoreCase("Airline"))
partnerHostingMast.setPartnerCode(partnerMast.getPartnerCode());
partnerMastService.save(partnerMast);     /* To be noted */
partnerHostingMastService.saveOrUpdate(partnerHostingMast);
ret_stat = "Success";
context.getExternalContext().getSessionMap().put("partnerMast", null);
} else {
partnerMastService.save(partnerMast);
ret_stat = "Success";
}catch(Exception e){
ret_stat = "Error";
FacesMessage message = new FacesMessage("Application facing some problem - Please contact administrator");
context.addMessage("error", message);
return ret_stat;
My Dao :
public PartnerMast save(PartnerMast entity){
try{
     System.out.println("Calling Save Method.............");
     entity.setIsActive("Y");
     getHibernateTemplate().save(entity);
     System.out.println("Record Saved..............");
catch(ConstraintViolationException e){
     System.out.println("Exception ..................."+e);
return entity;
I hope u got my question. Is there is any solution for this.
Pls Anyone help me out.

Hi,
I am able to catch the exception, how would i able to display the message in the JSF UI.
My Controller:
public String addAction() throws Exception
try{               
partnerMast = (PartnerMast)context.getExternalContext().getSessionMap().get("partnerMast");
partnerHostingMast = (PartnerHostingMast) context.getExternalContext().getSessionMap().get("partnerHostingMast");
this.getService();
if(partnerHostingMast != null && partnerHostingMast.getHostingPartner() != null && partnerMast.getPartnerType().equalsIgnoreCase("Airline"))
partnerHostingMast.setPartnerCode(partnerMast.getPartnerCode());
partnerMastService.save(partnerMast);     
partnerHostingMastService.saveOrUpdate(partnerHostingMast);
ret_stat = "Success";
context.getExternalContext().getSessionMap().put("partnerMast", null);
else {
partnerMastService.save(partnerMast);
ret_stat = "Success";
catch(Exception e) {
     ret_stat = "Error";
     FacesMessage message = new FacesMessage("Application facing some problem - Please contact administrator");
     context.addMessage("error", message);
       if(causedByBatchUpdateException(e)) {
              System.out.println("Yes Exception.........");
              FacesMessage message1 = new FacesMessage("Duplicate Entry...........");
          context.addMessage("error", message1);
                        //ret_sta="NO";
                 } else {
                         throw e;
          System.out.println("Before returning.............");
          return ret_stat;
          //return ret_sta;
}It is displaying the message saying "Yes Exception" in the console but not displaying the "Duplicate Entry" in the JSF UI.
Pls Anyone help me out.
Thanks,
