I'm using JSF in NetBeans. All I want to do is to include a page within another page. But whatever I tried, and when I run the main page, I get no error but I can't see my included page in a main page. Why? My main page is: <jsp:root version="2.1" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" xm...
I'm a total lexer and parser newbie, so please have some patience. Eventually I want to be able to express LDAP style Query strings, e.g. '(foo=bar)', '(!foo=bar)', '(&(foo=bar)(!zip=zap))' and have a tree in the end which I could use to create the actual database query (or whatever) So I thought to start with the simplest form, to pars...
Sometime ago I was facing the problem the other way around: how to drag an item (folder/file) from an explorer window (be it windows explorer, linux nautilus etc.) to the browser window - that is, the drag starts in one application and ends in the browser. Since I had control over the browser, I was able to intercept the dragend event: t...
Does anybody have a good analogy (or, failing that, a good resource) for describing the relationships between buffers, streams, readers, channels, selectors etc. in java.io and java.nio? Thanks ...
I've been using AppFuse to create my projects for a while now. And I'm already aware that there are two approaches to developing your DAO and Manager classes: GenericDao/GenericManager approach UniversalDao/UniversalManager approach I often find that using the Universal approach to be more convenient, because I just need one class t...
The Hibernate interfaces that you implement to provide event listeners, for example: org.hibernate.event.PostInsertEventListener; all extend Serializable. However, it doesn't seem to explain anywhere why your listeners need to be serializable. We've been injecting DAOs with database connections into them for a while, and it hasn't faile...
I'm trying to debug a problem in my Java application that throws no errors, no exceptions and doesn't even crash the app (it seems the failure happens in a separate thread). The problem seems to be inside a call to a library function (it's JAXBContext.newInstance(String) if that matters). The program will reach the line just before the ...

Hi, Right now we are using a customized logger method for our application but now we have a stand alone code for which we need to write to a separate log file. We have little idea about log4j. I just want to know where to change properties if any so that i don't disturb the existing logger application as well as we write our logs into...
This looks simple but I can't find a simple answer. I want to open a connection to a remote JMS broker (IP and port are known), open a session to the a specific queue (name known) and post a message to this queue. Is there any simple Java API (standard if possible) to do that ? EDIT Ok I understand now that JMS is a driver spec jus...
At the moment I am developing an annotation-based binding-framework for Java Swing that uses JGoodies Binding under the hood. Unfortunately I am stuck with an annotation for a JRadioButton-binding. What I want to do is specify a property-name of a model which holds a special value (enum). The radio-button shall be selected if this proper...
I'm using Java's SSLSocket to secure communications between a client and a server program. The server program also serves up HTTPS requests from web browsers. According to "Beginning Cryptography with Java", page 371, you should always call setEnabledCipherSuites on your SSLSocket / SSLServerSocket to ensure that the cipher suite that e...
I know that the audience of JIF is very small in numbers, but that's that Stack Overflow is for. My question has to do with if anyone has a snipset with which I can declassify a String and send it as output to screen. Example: String data{Alice:} = "123"; output.println("this is it" + data); note: more appropriate tag would be JIF, b...

Is there any way to open port specifically in a linux machine? I run 'netstat' command, and the port i use in my application doesn't appear. i...
What is the right way do validate a jpa query programmatically. Hibernate validates all annotation based named queries on entities. But how can I call this validation routine on programmatically builded jpa queries, to check for errors? @Entity public class Foo { @Id public int id; public String name; } main(...) { Query q = ...
Hi, Head First book says about include directive as include code from any other file into the JSP file at translation time, which can't be changed dynamically. However, I included a JSP file in the include directive, which generates a number randomly every time I access the page with include directive. And every time a new number gener...

I have a JEE5 application that exposes services using (local) session beans. When an internal fault occurs during service execution, a RuntimeException is thrown and encapsulated by JBoss(5.0.1) in a javax.ejb.EJBTransactionRolledbackException. The problem is that client applications receiving this EJBTransactionRolledbackException can...
