How to incorporate jsp code into html

Dear all, below is test.jsp coding, under the
<m:slides IPAddress  = "172.20.106.85" port = "3336" type = "mixed" locator= "file:///C:/m1.mov"/>
section, the IPAddress and locator is a static value, how can i make it into a dynamic values?

I have tried the following but it does not work

<% String myip="255.255.255.255" %>
<% String mediafile="file:///C:/m1.mov" %>
<m:slides IPAddress  = myip port = "3336" type = "mixed" locator= mediafile/>


//Actual test.jsp coding

<%@ taglib uri = "http://coyote/taglibs" prefix="m" %>
<html>
<head>
<title>Test Streaming</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>

<body>
<H2>Streaming</H2>
<m:slides IPAddress  = "172.20.106.85" port = "3336" type = "mixed" locator= "file:///C:/m1.mov"/>
<FORM METHOD = GET ACTION = main.jsp><INPUT TYPE = SUBMIT NAME= ACTION VALUE = "Next"></FORM>
</body>
</html>

what about when you posted what I suggested?

though the problem above appears related to something else, does the tag work when the value is hardcoded?

the error above does not appear to be caused by the value not being assigned correctly. It is possibly something unrelated.

change it back to
<m:slides IPAddress  = "172.20.106.85" port = "3336" type = "mixed" locator= "file:///C:/m1.mov"/>
if see if you still have problem, if yes, then the error must because of something else.
