GWT 1.6 Server class 'jar file' could not be found solution

While migrating to 1.6 to take advantage of its new features I was face with lots of headache addressing a lot of warnings that are so ridiculous since I don't understand why. I have been Googling for answers to this problems but I found no answer.

Out of despair I tried to solve things on my own by reading the manual. What more can I say I'm just too lazy to read those stuff.

During the process of migration a warning that keeps on popping in even though I assign the java build path makes me want to scream. It looks something like this...



After 5 hours of trying to search for answer I finally convince myself that I have to read the GWT manual and rely on my instincts. Here's the solution...



First of all at the start of my development with my pet project I always make sure that all the jar files are being categorize according to folders to avoid confusion or easy removal in case I want to.

Unfortunately, GWT 1.6 was not prepared for this (I guess) and all libraries that you use must be added to the /war/WEB-INF/lib folder any extra folder would result to a warning that I have shown above.

After removing and transferring the jar file to the main lib directory the result look something like this.







No more warnings baby! One down a hundreds to go...

Apple's Edge Over Microsoft?

In the world of IT, models created by business empires will dictate the future of their products. Microsoft is using the component model as the key to win customers and Apple is using the end-to-end model. Microsoft Windows platform crushed Apple's Macintosh platform the day Microsoft release Windows 98 and pirates come out in the open and dominate every stall in our local mall and computer shops. iPod maybe the best and coolest mp3 player that I have ever seen but I still don't think that Apple will dominate the cell phone era for this place belongs to Asia particularly Nokia and Sony Ericson. I don't know why Walter Mossberg thinks US company will always dominate the world when in fact there is another company that belongs to the world and its called Open Source. I think he is dead wrong with his perception. Without a doubt nobody comes close to iPod in the field of mp3 player however, with the release of Sony Ericson latest cell phone such as W900i. An intelligent human ...

I was looking for a nice place to chill last Monday to unwind my thoughts and enjoy with my family. I heard about the latest Internet Cafe just open 3 months ago and I decided to check it out. I have seen a lot of Internet Cafe but nothing comes close to this shop. Everything was simply high end from its ambiance, food and computers. It was simply the best place for people who want to collaborate and enjoy together.

GWT+MySQL Best Practice

Migrating from GWT-EXT to native GWT has never been an easy task as I expect it would. I took me some moths to really absorb the fundamentals of its Java code, structure and pattern. The price for taking this challenge was undoubtedly more gratifying especially on performance and size. I had lesser reboot due to memory leak and I had better handling on syntax especially on database due to its strict use of its object. Here are some improvements on my code: DatabaseServiceImpl.java String url = "jdbc:mysql://localhost:3306/"; String db = "mydb"; String driver = "com.mysql.jdbc.Driver"; String user = "myuser"; String password = "mypassword"; public String connectDatabase() { String resultString; try{ Class.forName(driver).newInstance(); conn = DriverManager.getConnection(url+db, user, password); //conn = DriverManager.getConnection...
