Default New to jasper reports

Hi,
I am new to this forum also to jasper reports. I downloaded the following
1.jasperreports-1.2.0-applet.jar
2.jasperreports-1.2.0.jar in the following directory.

C:\Documents and Settings\Administrator.
When I open this file I got the following error message.

Failed to Load Main-Class manifest attribute form
C:\Documents and Settings\Administrator\jasperreport-1.1.1-applet.jar

Why do i have this kind of error?
     thanks'

Did you open the file by double-click on the .jar file?
The error means that this jar file(jasperreport-1.1.1-applet.jar) is not an application. Since on Window platform you can create a jar file and allow it to be launched by double-click on it by specifying the "Main-Class" attribute in the Manifest file.

This jar file is just a regular jar file, technically it is a zip file since it uses the same compression method. You can use a WinZip utility on Window to open and extract it or using the jar command to extract its content.

To extract the content of the jar file by using the Java's jar command type the following at the command prompt(Make sure your PATH contains the path to you Java JDK):

jar xvf jasperreport-1.1.1-applet.jar

Hope this help.
