No explicit Transaction Handling:
Call to Servlet is JavaScsript :
xmlHttp.open("GET", url, true);
XMLHttpRequest.send(null)
blah, blah this all works OK...
SERVLET:
public void doGet(HttpServletRequest request, HttpServletResponse
response)
throws ServletException, IOException {
int key1 = Integer.parseInt(request.getParameter("key1"));
int key2 = Integer.parseInt(request.getParameter("key2"));
Service service = new Service();
//SUGGESTED TEST - PASSES!!
DataSource dataSource = null;
try{
Context initContext = new InitialContext();
dataSource = (DataSource) initContext.lookup(
"java:AMWEB");
} catch (NamingException ne){
ne.printStackTrace();
System.out.println(" NamingException: " +
ne.getMessage());
}
System.out.println(" dataSource: " + dataSource);
try{
service.deleteAttachment(fileLocation, key1,
key2);
}catch(DAOException e){
e.printStackTrace();
System.out.println(e.getClass().getName() + " : "
+ e.getMessage());
} catch(Exception e){
e.printStackTrace();
System.out.println(e.getClass().getName() + " : "
+ e.getMessage());
}
System.out.println(" RemoveAttachmentServlet returning."
);
// Write XML to response.
response.setContentType("text/html");
response.getWriter().write("removed");
}
Service Layer:
Connects to a WebService (Axis) then returns....
<CODE>
DaoManager daoManager = DAOFactory.getDAOManager();
SQLMapAttachmentDAOImpl dao = new
SQLMapAttachmentDAOImpl(daoManager);
rc += dao.deleteAttachments(key1);
</CODE>
WHERE THE SQLMapImpl is this
<CODE>
public class SQLMapAttachmentDAOImpl extends SqlMapDaoTemplateWrapper
implements AttachmentDAO
{
/**
*
* @param key1
* @param key2
* @return
*/
public int deleteSRCVisitAttachment(Integer key1, Integer key2)
throws IOException, ServiceException, FactoryException {
Map parametersMap = new HashMap();
parametersMap.put("key1", key1);
parametersMap.put("key2", key2);
delete("deleteAttachment", parametersMap);
return 1;
}
}
SQL
<delete id="deleteAttachment" parameterClass="java.util.Map">
DELETE
FROM TABLE
WHERE TABLE.KEY1 = #key1#
AND TABLE.KEY2 = #key2#
</delete>
</CODE>

Re: TransactionManager thorowing NPE
So is this datasource not working at all, or only for transactions?
If you can use the datasource to do selects ok, then the datasource is
setup
correctly and it's a transaction manager issue.
If you can't, then it's a jndi setup thing. I think because you could do
the InitialContext stuff, it isn't a jndi setup thing. And if that's
true,
then I'd like to see the code around this to see how you're handling
transactions.
