[rosa-users] Trouble getting started with Rosa

Tue Jun 28 10:29:36 EDT 2005

 From what I can see you are missing a couple of hidden form parameters :

<INPUT TYPE="HIDDEN" NAME="INPUT_TYPE" VALUE="">
<INPUT TYPE="HIDDEN" NAME="INPUT_COORD" VALUE="">

You should add those just after the <input type="hidden" name="action" 
value="">

  Here is a valid set of definitions as example for auto submit using a 
rectangle. Note that in this example the form variable CMD is used (in 
your case it is action).

Later,

<APPLET NAME="RosaApplet" ARCHIVE="./rosa/rosa_png.jar" CODE="Rosa2000" 
WIDTH="400" HEIGHT="300" MAYSCRIPT>
<PARAM NAME="TB_POSITION" VALUE="right">
<PARAM NAME="TB_ALIGN" VALUE="top">
<PARAM NAME="IMG_URL" VALUE="/ms_tmp/111996835517401.jpg">
<PARAM NAME="INP_FORM_NAME" VALUE="myform"><PARAM NAME="TB_BUTTONS" 
VALUE="zoomin|zoomout|recentre|pquery">

<PARAM NAME="INP_TYPE_NAME" VALUE="INPUT_TYPE">
<PARAM NAME="INP_COORD_NAME" VALUE="INPUT_COORD">

<PARAM NAME="TB_SELECTED_BUTTON" VALUE="zoomin">

<INPUT TYPE="HIDDEN" NAME="CMD" VALUE="">
<INPUT TYPE="HIDDEN" NAME="INPUT_TYPE" VALUE="">
<INPUT TYPE="HIDDEN" NAME="INPUT_COORD" VALUE="">
