When a checkbox is selected in a JSP, multiple data for that record is fetched and then uploaded to the action class for background processing *.hbm.xml in the case of a double primary key

========== Method 1:

--------1. Select the appropriate checkbox to remove the button after the click-------------

<!--******************* Delete *******************--
<input type= "image" alt= "Delete"
Src= "<%=request.getcontextpath ()%>/images/btnimg/btn_delete.gif"
Id= "DoDelete" name= "Action:dellocationaction!delete"
class= "Button_image" onclick= "return DelCheck2 ();"/>

--------2. Code---------------for JSP pages

<table id= "datashow" align= "center" border= "1" class= "tb3" width= "100%" >
<tr class= "Gridtitle" >
&LT;TD align= "center" ><input type= "checkbox" id= "Chkall"
Name= "Chkall" onclick= "Checkboxcheck ();" ></td>
<td>aaa</td>
<td>bbb
<% String varwerks= ""; %>
<input type= "hidden" name= "Werks_n" value= "<%=varWerks%>" >
</td>
</tr>
<%//string varwerks= ""; %>
<s:iterator value= "pagebean.list" status= "index" id= "CU" >
<s:if test= "#index. Odd = True" >
<tr class= "Gridspan" >
</s:if>
<s:else>
<tr>
</s:else>
&LT;TD align= "center" >
<input type= "checkbox" id= "CB" name= "IDs" value= "<s:property value=" Lgort "/>"/>
</td>
<td><s:property value= "Lgort"/></td>
<td><s:property value= "Werks"/></td>
</tr>
</s:iterator>
</table>

-------3. Reference JS Method---------------------------------

<script src= "<%=request.getcontextpath ()%>/js/checkbox.js"
Type= "Text/javascript" ></script>

-------4. JS Method------------

function DelCheck2 ()
{
var c=checkednums ();
if (c==0)
{
Alert ("You select at least one record as the deleted object.") ");
return false;
}
if (Confirm ("Are you sure you want to delete this record?") "))
{
//-------------
var count=0;
var tb= document.all.datashow;
var str2= "";
if (tb!=null)
{
for (i=0;i<tb.rows.length;i++)
{
var var1=tb.rows[i].cells[0].children[0];
if (var1.tagname== "INPUT")
{
if (var1.type== "checkbox")
{
if (var1.checked)
{
count=count+1;
var Td1=tb.rows[i].cells[1].innertext;
var Td2=tb.rows[i].cells[2].innertext;
if (str2== "")
{
STR2=TD2;
}
Else
{
str2=str2+ "," +TD2;
}
}
}//----if (var1.type== "checkbox")------>>>>
}//---if (var1.tagname== "INPUT")------->>
}//---for (i=0;i<tb.rows.length;i++)


/* Hidden fields record the selected sequence */
Window.form1.werks_N.value = str2;
/* Normal Submission Form */
Window.form1.submit ();
}//----if (tb!=null)---->>
return true;
}
return false;
}

------------5. Code in the Action class

Explode string
Public string[] Splitstr (String s) {
string[] ss = new string[200];
Decomposition at each comma character.
SS = S.split (",");
return SS;
}

Public String Delete () throws Exception
{
HttpServletRequest request = Servletactioncontext.getrequest ();
string[] ids = request.getparametervalues ("IDs");

if (ids = = null)
{
return SUCCESS;
}
String[] Ida=request.getparametervalues ("Werks_n");
is a string to decompose slipe
System.out.println (Ida[0]);
String[] Ss=splitstr (ida[0]);

for (int i = 0; i < ids.length; i++) {
System.out.println ("Print IDs" + ids[i]);
Locationbean Locationbean = new Locationbean ();
Locationbean.setlgort (Ids[i]);

System.out.println ("Print Ida" + ss[i]);
Locationbean.setwerks (Ss[i]);
Locationservice.deletelocation (Locationbean);
}
return SUCCESS;
}

====== method 2====== (Simple) ===========

---------1. Code in a JSP page
