Getting values from jsp page to java servlet

manpreet Best Answer 2 years ago

Hi actually I am facing issue in getting values from jsp page to java servlet. In a list of dropdowns only one dropdown value I am able to get all other values are coming as null. Not understanding where I am going wrong. Can anyone please help me.

In upload page all the values are coming fine. But the issue is only with retrieve page. I am unable to retrieve data as data is not passing from html to servlet.

Here is my html code:

<form method="post"   enctype='multipart/form-data'>

        <label>select Board:label>
        <select id="onelevel" name="onelevel" class="changeElem">select>
        <br>
         <label>select Syllabus:label>
        <select id="twolevel" name="twolevel" class="showElem changeElem">select>
        <br>
         <label>select class:label>
         <select id="threelevel" name="threelevel" class="showElem changeElem">select>
         <br>
          <label>select state:label>
         <select id="sixlevel" name="sixlevel" class="showElem changeElem">select>
           <br>
            <label>select subjects:label>
         <select id="fourlevel" name="fourlevel" class="showElem changeElem">select>
         <br>
          <label>select chapters:label>
          <select id="fivelevel" name="fivelevel" class="showElem changeElem">select>
          <br>

           <label>select terms:label>
          <select id="sevenlevel" name="sevenlevel" class="showElem changeElem">select>
          <br>







<button  id="retrieve">Submitbutton>
