I wrote a GWT portlets with Jetspeed a while back, but I never tried
to get two on the same page. I think the key is to remove the script
line from the portlet, and add it in during the doHeaders method of
your portlet.
<script type="text/javascript" language="javascript"
src="/googleportletapp/googleportletapp/googleportletapp.nocache.js"></script>
Another solution (not tested either) could be to set a render
parameter on the Jetspeed Request Context, and then just check for it
with a JSP, so that you don't include the script twice
<%@page import="org.apache.jetspeed.request.RequestContext"%>
...
<%
RequestContext ctx = request.getAttribute(RequestContext.REQUEST_PORTALENV);
if (ctx.getAttribute("com.griffith.app.googleportletRendered") == null) {
ctx.setAttribute("com.griffith.app.googleportletRendered", "true");
%>
<script type="text/javascript" language="javascript"
src="/googleportletapp/googleportletapp/googleportletapp.nocache.js"></script>
<% } %>
