[Building Sakai] take the value of site_id

If you use the Sakai App Builder and generate a JSP project, you will
see that in the tool/src/java folder there is an additional bean that
is injected with your ExternalLogicImpl via tool/src/webapp/WEB-INF/
applicationContext.xml
This makes your ExternalLogicImpl visible to the bean. you then need
to get that bean into the JSP. It's a bit of a roundabout way but
necessary to get classes visible and injected.
You've already setup the injection of the Sakai dependencies in your
Impl (ie toolManager et al) and that looks fine. The last step you
need is the bean in your webapp to link your Impl to the JSP.
You'll then see in the sample JSP files included in the application it
builds, how to get that bean into your JSP.
JSP:
<%
WebApplicationContext context =
WebApplicationContextUtils.getWebApplicationContext(application);
BakedBean bean = (BakedBean) context.getBean("bakedBean");
%>
Hello, <%= bean.getCurrentUserDisplayName() %>
then tool/src/webapp/WEB-INF/applicationContext.xml
<bean id="bakedBean"
class="org.sakaiproject.yourtool.tool.BakedBean" init-method="init">
<property name="externalLogic"
ref="org.sakaiproject.yourtool.logic.ExternalLogic" />
</bean>
cheers,
Steve
