Improving Performance in Jdeveloper 11g

From a user experience .... 

# Make sure you're on the latest version of 11G (5188). They make performance improvements with every release. 
# configure jdeveloper to open jsp/jsff's in source view. 
# Use the property editor if possible. Avoid typing in the source 
# Disable the source control plugin - Use Tortoise SVN or other source control outside of jdeveloper. 
# Recommend a minimum of 3G but 4G preferred 
# set the ide.conf memory size to at least 768 
# Restart jdeveloper if memory usage climbs above 1G 

Do you any tips? or more explanations to this?

Calling a Servlet From a JSF managed bean

Cases when you simply want to call a servlet for doing tasks like database interactions etc and you do not want to use a framework like ADF-BC, EJB-toplink(may be because your requirements are too small ) you can do it in the following way:

Say there is a bean like:

public class SubscribeBean {
...
.. some code
.....

public void validateConfirmEmailId(FacesContext facesContext,
UIComponent uiComponent, Object object) {

//to call servlet use below code
FacesContext fc = FacesContext.getCurrentInstance();
HttpServletRequest req = (HttpServletRequest)fc.getExternalContext().getRequest();
HttpServletResponse resp=(HttpServletResponse)fc.getExternalContext().getResponse();

try{
Command cmdSub = new DoSubscribe();
cmdSub.execute(req, resp); //this is a servlet defined as below
}catch(Exception e){
System.out.println("exception in SubscriberBean.java");
}
}

Please note that the two lines in the try catch block are specific to your needs. Like here DoSubscribe is another class implementing a servlet execute(request, response).

You can also use following code to call a servlet:
FacesContext fc = FacesContext.getCurrentInstance();
ServletContext sc = (ServletContext) fc.getExternalContext().getContext();
sc.getRequestDispatcher(url);
