!!Database Specific [#5]
* Why is the JSTL keyword 'empty' not working all the time?
;:''The empty keyword (pre JSP 2.0), only worked on java.util.List, java.util.Map, on Strings and arrays. Collections like java.util.Set were not supported. If you are using pre JSP 2.0 and want to test whether a Set is empty or not use: {{{
<c:if test="${mycollection['empty']}">.
}}}
The most reliable workaround to this problem I have found, is to use this notation:
{{{
<c:forEach items="${mycollection}" var="element" varStatus="rowNum">
<c:if test="${rowNum.count==1}">
<table>
<tr> <th> Value Header </th> </tr>
</c:if>
<tr>
<th>
<c:out value="${element.value}"/>
</th>
</tr>
<c:if test="${rowNum.last}">
</table>
</c:if>
</c:forEach>
}}}
This [article|http://weblogs.java.net/blog/mister__m/archive/2003/11/crazy_jstl_when.html] explains this in more detail. If you are using tomcat 5, this supports JSP 2.0 so you will not experience
this problem.''

So to access the Hibernate session from within your DAO, place a method like this in your DAO:
<div style="margin-left: 30px">
If you have an @hibernate.class tag on a POJO - hibernatedoclet will generate the mapping file into build/dao/gen. If you have a mapping file (*.hbm.xml) file for your POJO in the src/dao/**/model/*
directory, it will __overwrite__ the generated version. If you don't want to worry about the two conflicting - just remove the @ sign from @hibernate.class in your POJO and put your hbm.xml file in the {{model}}
directory.
At line 119 changed 1 line.
{{{
No build.xml modification are need for this to work. The "package-dao" target will include these mapping files:
At line 121 changed 1 line.
Session session = SessionFactoryUtils.getSession(getSessionFactory(), false);
{{{ <copy todir="${build.dir}/dao/gen">
<fileset dir="src/dao" includes="**/*.xml" excludes="**/*-${dao.type}.xml"/>
<filterset refid="variables.to.replace"/>
</copy>}}}
At line 123 changed 1 line.
}}}
If you want to get rid of the hibernatedoclet process, you can do that- but make sure and run it first - and then copy all of the generated hbm.xml files into your {{model}} directory.

* How do I get hold of the Hibernate session in my View code?
;:''To get hold of the Session in the view code, you need to lookup the SessionFactory defined in the applicationContext-hibernate.xml:
{{{
private void createApplicationContext() {
if (ctx == null) {
ctx =
WebApplicationContextUtils.getRequiredWebApplicationContext(servlet.getServletContext());
}
}
public net.sf.hibernate.Session getCurrentHibernateSession() {
createApplicationContext();
SessionFactory sessionFactory = (SessionFactory)ctx.getBean("sessionFactory");
SessionHolder sessionHolder = (SessionHolder)TransactionSynchronizationManager.getResource(sessionFactory);
net.sf.hibernate.Session currentSession = null;
Transaction currentTransaction = null;
if (sessionHolder!=null) {
currentSession = sessionHolder.getSession();
currentTransaction = sessionHolder.getTransaction();
}
return currentSession;
}
}}}
