Using Spring for J2EE apps

Image
By
There’s an interesting thread going on over at The Server Side based upon a comment made by Ugo Cei –
"I seriously wonder why anyone would want to develop anything substantial in Java nowadays without using Spring."

Having done J2EE applications using both "traditional" approaches (i.e. EJB 2.x) and more lightweight approaches (e.g. Spring), I’d choose the more lightweight approach every time. Probably the majority of J2EE applications don’t need the full J2EE stack and Spring provides all the tools necessary to get the job done. As I mentioned in a previous post, when I’ve done projects without using Spring, I’ve missed not having dependency injection (why should I really care about getting a database connection?).

EJB 3 looks interesting however, yet there is a large momentum with Spring at the moment, so I don’t see either technology toppling the other. I think both technologies will co-exists side by side.

A Simple Makefile for a GTK/GTKMM Project

By Anonymous
When compiling small applications, its fairly easy just to compile using g++ from the command line. If you’re compiling anything more complex than a single file, its probably easier to use a Makefile. This example Makefile demonstrates how to compile an application that uses the GTKMM library. NAME=my-app CFLAGS=-g -Wall -o $(NAME) GTKFLAGS=`pkg-config --cflags --libs gtkmm-3.0` SRCS=main.cc myapp.cc CC=g++ # Do all all: main # Compile main: $(SRCS) $(CC) $(CFLAGS) $(SRCS) $(GTKFLAGS) # Clean clean: rm -f $(NAME) rm -f *.h~ rm -f *.cc~ rm -f Makefile~ rm -f *.glade~

Changing Default Search Provider in Firefox on Linux Mint

By
On Linux Mint, the default version of Firefox is installed and configured to allow the following search engines to be queried directly from the address bar: Yahoo! Startpage DuckDuckGo Wikipedia Mint defines these as the default available set of search engines based upon 3 criteria (funding to Linux Mint, privacy support and whether the search engine is non-commercial). Other search engines such as Google, Bing or Twitter, etc. can easily be added into the default version of Firefox however. To add a different search provider, browse to Search Engines At the bottom of the page, click on the icon of the requested search engine, then click on the ... button in the URL bar and select the Add Search Engine option. You then have the option to change the default search engine within Firefox preferences to your new choice.
