So you want to evaluate a scriptlet variable in EL? Store it as a request attribute.

<%
    String var = "some";
    request.setAttribute("var", var);
%>

<c:if test="${param.variable1 == 'Add' && var == 'some'}">

However, this makes no sense. You should avoid scriptlets altogether and use JSTL/EL to prepare this variable. So if you make the functional requirement more clear, e.g. "How do I do this (insert scriptlet code snippet) using JSTL/EL?", then we'll be able to suggest the right approach.

For example, you could use <c:set> to set a variable in EL scope.

<c:set var="var" value="some" scope="request" />
