.jar files

[AdjLaz]

Hello. Im extremely new to webpage design and html. I really do not know code much at all. But I have built a website for my boss using Dreamweaver. I recently purchased a package to use in my website which involves me uploading a .jar file. However, I cannot get the program to work in dreamweaver. It appears as a blank java image in Dramweaver, and as a box with a red x on the server. This is the code:

<!-- BEGIN APPLET ELEMENT -->
<applet code="wwsw_SimpleLoan.class" archive="wwsw_SimpleLoan.jar" width="210" height="220" alt="Sorry, you need a Java-enabled browser to use this calculator.">
<param name="LOAN" value="95000" />
<param name="INTEREST_RATE" value="7.5" />
<param name="TERM_IN_MONTHS" value="360" />
<param name="POINTS" value="1.5" />

<param name="TitleFontColor" value="228B22" />
<param name="BackgroundColor" value="F3FFF3" />
<param name="LabelFontColor" value="3CB371" />
<param name="EntryBackgroundColor" value="FFFFFF" />
<param name="EntryFontColor" value="000000" />
<param name="AnswerBackgroundColor" value="98FB98" />
<param name="AnswerFontColor" value="0000FF" />
<param name="GridBackgroundColor" value="FFFFFF" />
<param name="GridLabelColor" value="228B22" />
<param name="GridBorderColor" value="CCFF99" />
<param name="GridFontColor" value="000000" />
<param name="GridHighlightColor" value="98FB98" />
<param name="GridHighlightFontColor" value="228B22" />
<param name="GridAnswerFontColor" value="663300" />

<param name="TitleText" value="Loan Calculator" />
</applet>
<!-- END APPLET ELEMENT -->

Hi ,jar file is a package of java class files .see .If you want to run Java class, there must have JRE in your OS.See How to install Java ,
After you install JRE in you OS,you can run applet.
