Answer 2

A:

You can not do this with just HTML. In your example it looks like you're doint it with ASP and i see no reason why this shouldn't work.

Answer 3

A:

The first one basically does this:

if (yes)
    out.println("<body onload=\"JavaScript:timedRefresh(120000);\">");
} else {
    out.println("<body>");
}

Is that syntactically valid? No, the first { is missing. You need to ensure that the Java code is syntactically valid. The second one is also syntactically invalid. You're attempting to invoke equals() on nothing.

That said, scriptlets are a poor practice. Rather use taglibs/EL. The JSTL <c:if> or the EL's ternary operator is perfectly suitable here. E.g.

<body <c:if test="${yes}">onload="JavaScript:timedRefresh(120000);"</c:if>>

or

<body ${yes ? 'onload="JavaScript:timedRefresh(120000);"' : ''}>
