I am trying to retreive a image from mysql database and display it on a jsp page.

But I am not getting how to set the size of the image...

Hi,

You need to used the BufferedImage class and the ImageIO class. I have done this recently within the confines of the Blackbord Learn platform. I hope this code snippet helps you out:

	BufferedImage bi = ImageIO.read(new File(fullPathBase + imgSrc));
		double currentWidth = bi.getWidth();
		double currentHeight = bi.getHeight();
		double displayHeight = 0;
		double displayWidth = 0;
		double ratio = 1.00;
		
		if(currentHeight > 150 || currentWidth > 150)
		{
			if(currentHeight >= currentWidth)
			{
				ratio = currentHeight / 150 ;
			}
			else
			{
				ratio = currentWidth /150;
			}
		}
		
		displayHeight = currentHeight / ratio;
		displayWidth = currentWidth / ratio;
		Double dEffectLeftPos = displayWidth - 4;
		int effectLeftPos = dEffectLeftPos.intValue();
		
	%>
	
	<div id="esfWelcomeImgCont">
	<img id="esfWelcomeImg" src="<%=imgSrc%>" height="<%=displayHeight %>" width="<%=displayWidth %>" title="<%=name%>" alt="<%=name%>" /></div>
	<div id="esfWelcomeTxtCont" style="left:<%=effectLeftPos %>px">
	<h3>Welcome to Compass</h3>
	<p><%=name%></p>

Note that the imgSrc variable has been set accordingly earlier in my application. Have look over the Java API for:
java.io.*
java.net.*
java.awt.image. BufferedImage
javax.imageio

This should see you right.
Hope it helps
