java.lang.ClassNotFoundException

I have embedded an applet (jar file)in a html page

Now when I am trying to access the web page , it is giving the following error.

<APPLET CODE="com.xxx.tru.ReadNFCSerialNumber" NAME="Read" ID="Read" MAYSCRIPT alt="Photo Id"   ARCHIVE="\test.jar, \ojdbc14.signed.jar, \ojdbc14_g.signed.jar" WIDTH="100%"  HEIGHT="100%"  HSPACE="1"  VSPACE="1">
</APPLET>




load: class com.xxx.tru.ReadNFCSerialNumber not found.

The web browser is trying to load your class from the URI http://localhost/popit/POPit/com/xxx/tru/ReadNFCSerialNumber.class instead of your jar file. The contents of the ARCHIVE attribute looks suspicious to me. Is it really supposed to be a comma-and-space delimited list? Also, the backslashes in front of the file names look suspicious:

ARCHIVE="\test.jar, \ojdbc14.signed.jar, \ojdbc14_g.signed.jar"

I would suggest you look into fixing the ARCHIVE attribute and then see if the web browser will load the class file form the jar as you want it to do.
