  <p>What I want is to get the id of button in another jsp button..am using liferay custom  mvc portlet so can anyone guide me that how to make it possible.</p>
  
  <p>Here is the snippet of code that I have tried.</p>
  
  <p>Following is my column of edit button:</p>
  
  <pre><code>&lt;td&gt;&lt;input type="submit" id=&lt;%=temprest.getPrimaryKey()s%&gt; onclick="return getbuttonId('&lt;%=temprest.getPrimaryKey() %&gt;')" value="edit" /&gt;&lt;/td&gt;      
  </code></pre>
  
  <p>...and on click of that button THE following Javascript will be invoked:</p>
  
  <pre><code> &lt;script type="text/javascript"&gt;
   function getbuttonId(sid){                 
  
          // document.editform.action=url;
          // document.editform.submit();
          var url="&lt;%= editURL.toString()%&gt;";
          window.location.href = url+"?sid="+sid;
  
          return false ;
    }
  
    &lt;/script&gt;
  </code></pre>
  
  <p>My portlet action url is as follows:</p>
  
  <pre><code>&lt;portlet:actionURL name="editRestaurant" var="editURL"&gt;
  
  &lt;/portlet:actionURL&gt;
  </code></pre>
  
  <p>...and the method I am calling via portlet action url is here in my action class:</p>
  
  <pre><code>public void editRestaurant(ActionRequest reqeust,ActionResponse response) throws Exception
  {
    String str=  reqeust.getParameter("sid");
    long l=Long.valueOf(str);
  
    //Retriev table data using Primary key
  
    restaurant rest=restaurantLocalServiceUtil.getrestaurant(l);
  
    //Set Attribute which has all values of specified pk.
    reqeust.setAttribute("edit",rest );
  
    // Redirect to Jsp page which has Update form. 
    response.setRenderParameter("jspPage","/jsps/edit_restaurant.jsp");
  
  }
  </code></pre>
  
  <p>I got error like this when I click on edit function</p>
  
  <pre><code> java.lang.NoSuchMethodException: emenu.advertise.portlet.RestaurantPortlet.editRestaurant?sid=5(javax.portlet.ActionRequest, javax.portlet.ActionResponse)
  </code></pre>
  
  <p>Can somebody please guide me to fix this?</p>
