Dear JSP gurus,
Using JSP, I am displaying images using a 1-d array of image nos. into a
webpage.The array
actually consists of only the image nos.(without the extn.), corresponding
to the image file names in a directory.
In the JSP, I am using the following piece of code to display the images.
<%!
int row;
String[] rowData;
String getRowData( int row )
{
return ( "" + rowData[row] + ".jpg" );
}
%>
**** I am then assigning an array of image nos.(without the extn.) from
a servlet to this rowData[] in JSP.****
**** Then for displaying the images , I am using the following piece of
code( given below in brief)****
<% for ( row=0; row< rowData.length; row++ )
{
%>
<img src = "<%= getRowData(row) %>" >
<%
}
%>
Now, the problem is that the extn. of image is not const.
It can be .jpg or .gif or .jpeg
So, I need to check the extn. of each image . which I am calling from this
directory, & accordingly assign the extn. in the getRowData(row) method at
runtime.
I don't have the slightest idea as to how to check the image ext. from the
directory for the image that I am calling.
Could anybody pl. help?
Any help will be greatly appreciated.
