I have TViewerApplet.class in com.abc.applet package.To sign the jar file I followed following steps:

1) Created jar file of com folder using cmd jar cf Viewer.jar com

2) Signed jar file using cmd

 jarsigner -keystore "C:\Documents and Sett
ings\compstore" -storepass abcdef -keypass abcdef
-signedjar "C:\Documents and Settings\SignedViewer
.jar" "C:\Documents and Settings\Viewer.jar" signFiles

Added the below tag in jsp file

<applet name="viewerApplet" id="TViewerApplet" width="100%" height="500" code="com.abc.applet" align="baseline" codebase="." mayscript="mayscript" archive="SignedViewer.jar,cmbview81.jar"> </applet>

But the problem is I get 

Caused by: java.io.IOException: open HTTP connection failed:http://10.160.120.221:8086/ICMViewer/com/abc/applet.class

Looks like the problem is not that you signed your applet, but rather that it's a misconfiguration of your applet-tag in html.

  • You specify the file name of the applet in your code-attribute. Looking at the definition, it seems to me that you only defined the name of the package. – Kurt Du Bois Jul 26 '12 at 06:46
