Hi all,
Up until now, I've been working with Fedora AMIs in my quest to master working with virtual servers on AWS. Today I jumped over to an OpenSolaris AMI.
I love it! The pkg command makes things very easy.
So far installing things like Ant, JDK, and MySQL have gone perfectly. I'll write more as I learn.
Cheers!

Hi all,
Here is another installment on working in the cloud, the AWS cloud that is. Today's topic: creating a custom AMI. This may sound like as easy task. And it would have been, had AWS documentation been up to scratch. I spent lots of time messing around with this, and I finally got it to work. Here's how:
scp -i ~/.ssh/<yourkeypair.pem> ~/.ec2/<pk-whatever.pem> ~/.ec2/<cert-whatever.pem> root@your-public-DNS:/mnt.The

In the previous blog, I mentioned SQL Editor. NetBeans has improved it in every release in the past 2 years and it looks great these days. Here’s a sneak-peek;
This figure shows the SQL Editor window along with the results shown for the command executed, written in the editor (select * from nbusers). Also, you can see numerous toolbar buttons, and results are shown in similar way as if it was any CRUD application. We will discuss this in more detail in
[Read more...]I have been busy lately thanks to my internship project, which almost got screwed up. I was working in a team of 4 people, where we were building a web application, that was initially deployed at JBoss Server using JBoss Eclipse IDE (old version). Also, we had to interact with the centralized Oracle Server to setup our database for running the website.
Now, having being trained on some of those technologies in past few months, I thought it won’t be much of an issue. However, at the beginning of this month, I faced some weird issues which had no obvious answers. There weren’t any silly mistakes either. We were facing some issues with Oracle connectivity. I am not blaming Oracle or the company where we did the project. But, mix of old and new technologies, turned out to be quite confusing resulting in lot of trouble.
We were running out of time, so we

I switched on my machine this morning thinking a new day will bring new results. Nope. Same old results. As I mentioned in an earlier blog entry, I created a server instance using Fedora with LAMP, complete with MySQL. Hmmm.. Sound good? Well, it comes with MySQL 4.1. Normally an update would be a straightforward process. Since Fedora 8 doesn't come with an
apt-getcommand, I chose to go the
yumroute. I tried
yum update mysql-server. No dice. problems. I spent another 30 minutes or so, trying to correct the problem, but to no avail. So I decided to create a whole new server instance with Fedora 8 and no MySQL. I manually installed MySQL on the machine, by doing the following:

Hi all,
Today I'll be write more about my experiences with Amazon Web Services. Before I continue, I'd like to provide some background information.
I signed up for Amazon Web Services. I used the Fedora LAMP AMI to create a server instance. The main reason for choosing this AMI was its inclusion of MySQL and Apache, a nice little package indeed. I ran into a few problems at first. Because I am based in Europe, I am allowed to use only the EU-West region, and the default in the US-East region. The drop down list is rather small, and i took a couple of unsuccessful instances to figure out that this was the problem. When I say "unsuccessful instances," I mean that the nothing appeared in the browser when I copied the public DNS to the browser's address bar. I attached an EBS volume to the server instance and it was OK.
Now for more on the command line.

I've just been reassigned (partially) to make sense of using a MySQL database server in the cloud, namely in Amazon Web Services. I'll be blogging about my experiences. Today is part 1.
After creating the account, I got to work. I signed up for EC2 (Elastic Compute Cloud 2), Simple Storage, and EBS (storage that allows for persistence). I played around with starting an instance, terminating it, etc. Then I got started with the command line tools. This is what I did.
export JAVA_HOME=/Library/Java/Home/in the terminal. Then I typed
$JAVA_HOME/bin/java -versionto confirm that the JAVA_HOME was indeed set correctly.

Hi all,
If you expand a database connection node in the Services window of the IDE, you'll notice a new look. What are all of these nodes under the connection nodes? They're schemas. For the most part, if you're using Java DB, the only schema you'll need to worry about is the app schema. I'd be interested in knowing what developers have used the other schemas for.
When you expand the MySQL conect node, what you get is a list of databases you've created in MySQL. These database are actually schemas you've created in your MySQL database.
There you have it.
Cheers!

I recently noticed several new books based on GlassFish Server, like Yuli's book on Java EE and DBs, Using MySQL and GlassFish and Antonio's book on Java EE 6 with GF v3. Looking a bit more I also found that David also has a new book on NetBeans 6 and Java EE 5 (w/ GF) and Adam has one on the

Mon-Thu I'll be attending the MySQL User's Conference here in Santa Clara. The tone of the conference is noticeably different to that of its (even larger) sibling JavaOne in San Francisco, and the topics are very grounded in the practical needs of the Users of the technology. There are many very interesting talks, below is a small selection extracted from my Personal Schedule.
Starting with those related to topics we normally cover here: Several BOFs:
