I would like to include a JSP page into another JSP page. Let's say that I have master.jsp that is including slave.jsp.
As slave.jsp has its own <head> section for dealing with JavaScript and CSS, is there a way or maybe another method to merge the masterand slave HEADs section into a single one? Also the same should done for the BODYs section.
I have been using sitemesh recently but I think is quite impractical to setup a template for each page.

I went for this solution by passing a parameter when including the page.
in master.jsp
<head>
blablabla
<c:import url="slave.jsp">
<c:param name="sectionName" value="HEAD" />
</c:import>
</head>
<body>
blablabla
<c:import url="slave.jsp">
</c:import>
</body>
and then in slave.jsp the parameter is read and the custom part of the page is rendered.
<c:choose>
<c:when test="${param.sectionName == 'HEAD'}">
head section here [without the <HEAD> tags !]
</c:when>
<c:otherwise>
body section here [without the <BODY> tags !]
</c:otherwise>
</c:choose>
not too nice to see but working. In this way I am able to remove the duplication of HEAD and BODY parts.

You cannot and should not merge two <html> documents in each other. This would produce invalid output. Better include CSS/JS conditionally with help of JSTL c:if or c:choose tags.
Basic example:
<head>
<script type="text/javascript" src="global.js"></script>
<c:if test="${isAdminPage}">
<script type="text/javascript" src="admin.js"></script>
</c:if>
</head>
