[mohammed_amr]

Dear Gurus,

I'm trying to customize manage-task-dialog.jsp page to add a button called "scan Resource" and this button is associated to applet, and that applet use the twain dll file to talk with scanner driver and scan the image.

i'm trying from 12 hours past with any successful result and till now i have the following status

- manage-task-dialog customization (done)
- applet development to talk with twain scanner driver (done) within jar file
- applet jar is imported to the WEB-INF/lib and imported to the project properties [eclipse]
- embed applet with manage-task-dialog page (failure) from the tag

<jsplugin type="applet" code="com.ds.ui.presentation.ScanningApplet"  archive="scanningApplet.jar"  ></jsplugin> or when i use the tag <applet></applet>

and the message of exception is as follow:

java.lang.ClassNotFoundException: scanningApplet

Till now an error is appear, and i need a help.

Thanks
Mohammed Amr.

Since the applet is not part of the server application, it should not go to WEB-INF/lib, but rather live in some path which is available to the client - say /res/scannerApplet.jar and then adjust <applet> tag.

BTW, i am curious which libraries did you use to talk to twain? Something opensource, homegrown or commercial?
