I have a question concerning cfTree.
I'm invoquing the tag by
<APPLET NAME="Navigation" CODE="allaire.controls.CFTreeFormApplet" CODEBASE="/CFIDE/classes/" HEIGHT="500" WIDTH="250">
 
CFIDE/Classes/ is mapped in IIS and CFAdmin.
 
When loading the page in IE, the applet appears without graphics;
 
NS reports Applets allaire.controls.cfTreeFormApplet class allaire.controls.cfTreeFormApplet could not be loaded
 
Any Ideas?

I think that when you use the CFTREE tag to invoke the applet some javascript is created. Perhaps this has some effect on the display. Also, presumably there are some params that have to be given to the applet so it knows what to produce.

The script produced on my machine looks like this:

<script LANGUAGE=JAVASCRIPT TYPE="text/javascript" >

<!--


// Function, called by Java applets, to set a specified form param's value.
function _CF_setFormParam( strFormName, strParamName, strParamValue )
     {
          var strObjName = "document." + strFormName + "." + strParamName;
          var obj = eval( strObjName );
          obj.value = strParamValue;
          return true;
     }


function  _CF_checktestForm(_CF_this)

    {

    return true;

    }


//-->

</script>


The code to call the applet looks like this:

<!--- Load and run the custom, Java form control. --->
<OBJECT
  CLASSID="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
  CODEBASE="/CFIDE/classes/cf-j2re-win.cab"
  STANDBY="First use of this control. Configuring browser. Please wait..."
  WIDTH="200"
  HEIGHT="320"
  ALIGN="LEFT"
>
    <PARAM NAME="CODE" VALUE="allaire.controls2.CFTreeApplet.class">
    <PARAM NAME="ARCHIVE" VALUE="/CFIDE/classes/CFJava2.jar">
    <PARAM NAME="MAYSCRIPT" VALUE="true">
    <PARAM NAME="APPENDKEY" VALUE="yes">
    <PARAM NAME="BORDER" VALUE="yes">
    <PARAM NAME="HSCROLL" VALUE="yes">
    <PARAM NAME="ROOT" VALUE="no">
    <PARAM NAME="SEPARATOR" VALUE="yes">
    <PARAM NAME="SHOWLINKS" VALUE="yes">
    <PARAM NAME="TREEITEMS" VALUE="%2D1%01test">
    <PARAM NAME="VSCROLL" VALUE="yes">
    <PARAM NAME="_CF_FORM_NAME" VALUE="testForm">
    <PARAM NAME="_CF_PARAM_NAME" VALUE="__CFTREE__testForm__test">
    <B>Custom control could not be displayed because this browser does not suppport Java2.</B><BR>
</OBJECT>

I have tested this in a static HTML page and it renders correctly, but I am running CF 5.0 so you may find that your code works slightly differently.

Thank you, Spike

I spent quite some time on this issue and tried several things; finally I tried to copy the whole classes-folder with all classes into the website and this helped.
