most places where you get applets give you a ssample HTML code, or they give you the page itself. Just use that.
A sample code:
<applet code="Othello.class" width="550" height="530" align="center">
Sorry; you don't have a java enabled browser. UPGRADE NOW! </applet>
The above code doesn't have an archive or a codebase as the below one:
<applet codebase="./applet" archive="Jigsaw.jar" code="Jigsaw.class" width="650" height="449">
<param name="AllowSolve" value="true">
<param name="AutoSnap" value="15">
<param name="BgColor" value="2">
<param name="BreakupText" value="Breakup">
<param name="CanRotate" value="true">
<param name="Cols" value="3">
<param name="Connector" value="-1">
<param name="DimHelpImage" value="60">
<param name="Image" value="archi01.jpg">
<param name="ImgHeight" value="256">
<param name="ImgWidth" value="384">
<param name="InnerFrameColor" value="#800000">
<param name="KeepBoardClear" value="true">
<param name="MessageText" value="Jigsaw solved!">
<param name="OuterFrameColor" value="#800000">
<param name="Rows" value="3">
<param name="SelectColor" value="#FF0000">
<param name="SolveText" value="Give up">
<param name="TextColor" value="#ffff00">
<param name="TidyText" value="Organize">Sorry; you don't have a java enabled browser. UPGRADE NOW!
</applet>
The idea of an archive is like to zip all the files in one file. The codebase is the directory in which the applets are placed. It is best to put ll the files in one folder. In this case you don't put a codebase (leave it blank)
