[tikku online]

Hi Please refer the below example as below detailed the multiple upload is done by normal html and the form bean but as I am having my old big size jsp in struts html tags so how can i achieve this .

As I am getting No getter method exception for my setter getter in form bean as below;
..............................my...formbean............................................................
public List getDocPath()
{
log.info("---getDocPath(FormFile docPath)-----");
return this.casestartbean.getUploadFiles();
}
public void setDocPath(int iIndex, FormFile docPath){
this.casestartbean.setUploadFiles(iIndex, docPath);
}
................................................In my JSP....................................................................
<% for(int j=0;j<noofdocs;j++)
{
String fileId = "docPath[";
fileId = fileId.concat(Integer.toString(j)+"]");
%>
<TD align="center" width="5%" rowspan="1"><%=j+1%></TD>
<TD align="center" width="65%">
<html:file property="<%=fileId%>" styleClass="textbox" size="55" onchange="showTable()"/></TD>
...............................................the.....StackTrace...I m getting....................................
