Populating textbox in jsf on clicking submit button

Question

I am having inputText box, dropdownlist , outputText box and a submit button in my jsp page.
I am pre populating the dropdown list from my managed bean. Also setting the values using setter methods that is input in inputText box and dropdownlist using managed bean.
On clicking the submit button and based on selected item from the drop down list, I need to perform populating outputText box with return string from getter method from bean.
But I am not sure how to handle this. Please find few lines of code below...
<h:inputText id= "mnNum" value="#{UserBean.mnNum}" size="18" maxlength="17" styleClass="TxtSz12 LH18" tabindex="1" title="Man Number"/>
<h:selectOneMenu id="lstService" value="#{UserBean.serviceType}" tabindex="3">
   <f:selectItems value="#{UserBean.getServiceItems}"/>
</h:selectOneMenu>
<h:commandButton  action="#{UserBean.submit}" id="submitButton" value="Generate"/>
<h:outputText value="#{UserBean.getRequest}" />
public class UserBean extends FacesBean {
public String submit() {...}
public void setServiceType(String serviceType) {...}
public String getRequest() {
if(serviceType.toString()=="SearchService")
return "abc";
else if (serviceType.toString()=="basicService")
return "xyz";
else
return null;
}Please assist how to do it when submit button is clicked. I can redirect to different jsp file on click of the submit button. But I dont want to do that and I need to populate the output textbox in the same page !
If anything is not clear please let me know. Thanks in advance.

Answer 1

Page is coming up but lstService dropdown box is not displayed at all. But mnNum inputText and submitButton is showing properly.
Also after pressing submit button, "abc" text must be displayed in outputText box. But its also not displayed. Instead, the below error is shown,
Error opening /portlets/tools/webservicehelper/webservicehelper.faces.
The source of this error is:
java.util.MissingResourceException: Can't find bundle for base name resources.bundles.ValidationMessages, locale en at java.util.ResourceBundle.throwMissingResourceException(ResourceBundle.java:1521) at java.util.ResourceBundle.getBundleImpl(ResourceBundle.java:1260) at java.util.ResourceBundle.getBundle(ResourceBundle.java:962) at javax.faces.component.MessageFactory.getMessage(MessageFactory.java:102) at javax.faces.component.MessageFactory.getMessage(MessageFactory.java:175) at javax.faces.component.UIInput.validateValue(UIInput.java:1001) at javax.faces.component.UISelectOne.validateValue(UISelectOne.java:130) at javax.faces.component.UIInput.validate(UIInput.java:868) at
