Hi,

I'm looking for a way to provide the client side with a Print window so that he/she can select the printer where the document can b printed.
So i've wriiten a JApplet code which pops-up the Java Print window and was able to print the document when invoked it on my local PC.

But when tried to call this applet from an HTML page that was deployed on the tomcat server, it was not showing any print window.
So can u tell me is this bcoz Applets r not given access to client side resources? If yes, is there any other alternative for providing this functionality?

Kindly reply me asap as this is urgent requirement.

Thanks.

if you want to print an html page, use window.print() from within the html (javascript).

if you want to use the applet, you will have to sign it:

//generate a key
keytool -genkey -keyalg rsa -alias your_alias_here
//save the certificate
keytool -export -alias your_alias_here -file your_certificate.crt
// sign the jar file
jarsigner your_applet.jar your_alias_here

Not sure how you embedded your applet in the html, but I had this once:

    <APPLET  CODE = "./my_applet.jar" WIDTH = "775" HEIGHT = "385" NAME = "applet" VSPACE = "10" HSPACE = "10">
            <PARAM NAME = CODE VALUE = "package.to.PrintApplet" >
            <PARAM NAME = CODEBASE VALUE = "." >
            <PARAM NAME = ARCHIVE VALUE = "./my_applet.jar" >
            <PARAM NAME = NAME VALUE = "applet" >
            <PARAM NAME="type" VALUE="application/x-java-applet;version=1.4">
            <PARAM NAME="scriptable" VALUE="false">
      </APPLET>

then place the jar file and the html file at tomcat_home/webapps/your_web_app/
