Dicoogle PACS: A distributed medical image system (Open source solution)

I’ve been developing a project since 2 years ago dubbed Dicoogle PACS [1] . I didn’t start the project, but when I started with the project I really enjoyed and it was modified gradually with new architecture. This project was started in IEETA [2], in bioinformatics group [3] and RSI Course.

Today it has many features, few of them list follow:

• Indexing Engine (extension of the traditional and retrieving engine)
• Query and Retrieve through free text and meta data
• PACS engine that allows to index and query DICOM studies/files over a set of distributed repositories
• DICOM services
• Accessible by Webservices
• P2P Layer (based on JGroups)
• Server/Client Architecture (RMI based)
• Reduced installation and maintenance costs
• Open Source and Platform Independent (Windows, Linux, Mac)

We’ve learned a lot with this project in many areas, so just an overview:

• Developing for users is difficult. Keep closest of them!
• Scalability solution is hard to reach. Think Different!
• You need to be motivated!

Actually there are other people contributing and developing for the project, and I hope that it continues.

Stay tunned, new are incoming!

Java webservices without Tomcat, GlassFish or platform-dependent server

Greetings,

When I was developing an application in Java to my job I have a situation to solve: build a webservice and consumer as well. Despite the Netbeans have several wizards to create WebServices my application couldn’t have a dependence like GlasshFish , Tomacat or other stronger server.

After some time I found Axis2 [1] and some useful samples teaching how to do that. A sample consumer can be found here [2]. Then you can build the service, and there are to many samples in userguide (see simple example [3]). Now it was missing run it as a server, but it’s pretty easier as well, just look there:

public static void main(String args[]) throws AxisFault
{
AxisServer s = new AxisServer();
s.deployService(MyService.class.getName());

}

And it will run on port 6060, go for it: http://localhost:6060. It is also possible change the port in which server runs, using ConfigurationContext and SimpleHTTPServer.

Cheers!
