MY problem is :
After deploy my war into my tomcat6.0.29, run my application. When i click the a4j:commandbutton the following error occur
HTTP Status 404 - /.jsp not found
type Status report
message /.jsp not found
description The requested resource (/.jsp not found) is not available.
Apache Tomcat/6.0.29
Help me. Thanks in advance
The return value of your action is used to find the new view to display. Either by finding a match for it in faces-config or if there is no mapping there by using it directly as the name of the page. As you return an empty string you end up with only .jsp as the filename. If you want to go back to the same page return null instead of an empty string.
Return null in displayButtonAction method
public String displayButtonAction() {
displayValue = username;
return null;
}
OR rewrite your action method with return type void
public void displayButtonAction() {
displayValue = username;
}
