从JSP脚本标签调用Java函数

Question

I have a JSP file as below

<SCRIPT>
function validateEvent(){
 // I want to call Java function myProfile() here
 }
 </SCRIPT>

 <html:select property="event" styleClass="input"   onchange="validateEvent();">
  </html:select>

All I want to do is, call the java function myProfile() from validateEvent() function, that gets triggered on change of the value in event dropdown. Any help in this regard would be greatly appreciated.

You can't use a <script> tag to execute a java method server-side from the client. Those tags corresponds to Javascript, which is executed on the client side, and therefore it doesn't have access to what's going on on your server directly.

If you need to retrieve information from your server, have a look at something called AJAX.
