Creation of Dynamic rows in javascript
Create a html file with this code and check the functionality:
<html>
<head>
<script LANGUAGE=”JavaScript”>
function addRow(tableID){
var table = document.getElementById(tableID);
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);
var cell1 = row.insertCell(0);
var element1 = document.createElement(“input”);
element1.type = “text”;
element1.name = “empNo”;
cell1.appendChild(element1);
var cell2 = row.insertCell(1);
var element2 = document.createElement(“input”);
element2.type = “text”;
cell2.appendChild(element2);
var cell3 = row.insertCell(2);
var element3 = document.createElement(“textarea”);
element3.setAttribute(“name”,”mytextarea”);
element3.setAttribute(“cols”,”10″);
element3.setAttribute(“rows”,”1″);
cell3.appendChild(element3);
}
function deleteRow(tableID) {
var table = document.getElementById(tableID);
var rowCount = table.rows.length;
if(rowCount > 1) {
table.deleteRow(rowCount – 1);
}
}
</script>
</head>
<body>
<form name=”f1″ id=”f1″>
<input type=”button”value=”Add” onclick=”addRow(‘datatable’)”>
<table id=”datatable” cellspacing=”0″ border=”1″ bgcolor=”#738711″>
<tbody>
<tr>
<td><input type=”text” ></td><td><input type=”text”></td><td><textarea rows=”1″ cols=”10″></textarea></td>
<td><a href=”javascript:void(0);” onclick=”deleteRow(‘datatable’)” >Remove</a></td>
</tr>

Conversion of string into uppercase
The below function is used to convert the alphabets into uppercase
function convertToUpper(){
var field1 = document.formName.elementName
field1.value = field1.value.toUpperCase();
}
Example :
If the formName is StudentForm and element name is student id like stud100
Then ,
function convertToUpper(){
var field1 = document.StudentForm.StudentId
field1.value = field1.value.toUpperCase();
}
gives the value as STUD100.

ENABLING JMX PORT IN WEBLOGIC
Weblogic runs with domains. With different domains you can enable the JMX port by fallowing the below steps.
Step 1: Go to your domain bin folder, which you want to enable JMX remote port.
Ex: C:\bea\wlserver_10.3\samples\domains\wl_server\bin
Step 2: edit the “setDomainEnv.cmd” file and add the fallowing code as above line of the set CLASSPATH
set JAVA_OPTIONS= %JAVA_OPTIONS%
-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=8006
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false
Step 3: Restart the weblogic server.
Step 4 : Try to connect for the Jconsole with host:8006, It will connect to your domain of weblogic server.
