How to get text between <option> tag in servlet </option>

I have select in my index page. It looks like below

<div id="dropdown" class="input-group" style="width:50%">
                    <select class="form-control" id="select2" name="select2" onchange="javascript:document.form1.submit();" style="width : 250px">
                        <option value="C:/path1" >option 1/option>
                        <option value="C:/path2" >option 2</option>
                        <option value="C:/path3" >option 3</option>
                        <option value="C:/path4" >option  4</option>
                        <option value="C:/path5" >option  5</option>
                        <option value="C:/path6" >option 6</option>
                    </select> 
                </div>

I need value of "Value" attribute i.e., "C:/path1" which I'm able to fetch in Servlet using 

String value= request.getParameter("select2");

Now I need to fetch text between tag i.e., I need "option 1" or anything based on selection. How can I do it. Kindly help. Thanks in advance :)

With form you can only value of selected option if you want the option label as well then you need to write extra logic to send the data to server.

<div id="dropdown" class="input-group" style="width:50%">
    <input type="hidden" name="selectedLabel" id="selectedLabel">
    <select class="form-control" id="select2" name="select2" onchange="javascript:getSelectedLabel(this);" style="width : 250px">
       <option value="C:/path1" >option 1/option>
       <option value="C:/path2" >option 2</option>
       <option value="C:/path3" >option 3</option>
       <option value="C:/path4" >option  4</option>
       <option value="C:/path5" >option  5</option>
       <option value="C:/path6" >option 6</option>
    </select> 
</div>

JS: using this function you set the option label to hidden field and the hidden field will be sent along with your form data.

function getSelectedLabel(sel) {
    document.getElementById("selectedLabel").value = sel.options[sel.selectedIndex].text;
    document.form1.submit();
}

Server side: 

String value= request.getParameter("select2");
String label = request.getParameter("selectedLabel");

here the simple and quick solution.

Try this 

<select class="form-control" id="select2" name="select2" onchange="javascript:document.form1.submit();" style="width : 250px">
                    <option value="C:/path1_option 1" >option 1/option>
                    <option value="C:/path2_option 2" >option 2</option>
</select>

If your send the data to servlet like this (path + option text) the you can get the data by request.getParameter() method and split the data using java code.

String value= request.getParameter("select2");
String vals[]  = value.split("_",0);

for(String v : vals){
    System.out.println(v);
}

so, you can get these two values....
