I was creating a HTML Jasper Report. It was working fine, but I saw many failed images. When I see the source, I found many image tags like the following.
<img alt="" src="nullpx" style="width: 20px; height: 24px;"/>
When I googled, I found an image property need to be set to give the proper image name.
JRExporter exporter = new JRHtmlExporter();
...
exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
exporter.setParameter(JRExporterParameter.OUTPUT_WRITER,printWriter);
...
exporter.setParameter(JRHtmlExporterParameter.IMAGES_URI,"image?image=");
....
exporter.exportReport();
I need to search whether we can avoid it. anyway this is a temporary solution. I created a servlet to create transparent empty GIF and called it over here.

I was writing a servlet whose response is PDF, CSV, XLS etc. This works fine, but when I tried to save it HDD the url is given as the filename. I was wondering how to explicitly specify the filename. Here is the solution.
response.setHeader("Content-Disposition", "inline; filename=xyz.pdf" );
When we set this header property in the response, The filename will be xyz.pdf. Nice na!

I am thinking about this for long time. I am not able to write a single page in php. Today I did it. Just to share it with you 
<?php
//title
$title = 'PHP Test';
?>
<html>
<head>
<title><?php echo "$title";?></title>
</head>
<body>
<?php
//create an array
$myArray = array('this', 'is', 'a', 'PHP', 'Test');
for ($i=0; $i<5; $i++)
{
echo "$myArray[$i]";
echo '<br>';
}
?>
</body>
</html>
Prints the following in the browser
this
is
a
PHP
Test

Friends,
This is to give you a code pack I wrote today. I was listening to one of the internet radios in Tamil. I want to store it on my hdd, the tools I searched dint helped me much. I want a simple tool, that saves my time. And It should be able to work in my absence. I wrote couple of classes, which I am going to test it now.
Why dont you test it youself
It doesnt require any installation. you need only three files.
mp3_stream_extractor.jar, The execution binary,
RUN.CMD, the invoking script
radio.properties, where you configure the radios
run the run.cmd, The audio is extracted to your home folder automatically.
Enjoy.
Download MP3 stream extractor
