Hello

CORBA (Common Object Request Broker Architecture) is a standart defined by OMG (Object Management Group), this let distributed object from different languages and OS to communicate. It also provides total transparency in the communication. The IDL (Interface Definition Language) is the tecnology used to describe the interfaces. IDL has your own data types, that are mapped to the data types in other languages. There is an IDL compiler, it generates the codes that do the communication.

But how it works? We have some definitions in a .idl file, in this case Bank-idl (remember to change the filename).

Hello

Tooday Jorge send me an e-mail asking how to send files using XML-RPC. So I did some modifications in Client and Server, Java XML-RPC to do this.

I implemented this and it wasn’t so hard. I read the documentation of Apache XML-RPC to see how to send bytes. They are send using an array of bytes (byte[]) in a Base64 codification.

To create the Base64 codification I used Java Base64 in public domain.

How to get an array of bytes from a file

PS: This is just an example, any file that client ask, the server will send. It WILL BE A SYSTEM VULNERABILITY!

Good night,

A few days ago I created a XML-RPC server to test some functions. What is XML-RPC? XML-RPC is a remote procedure call (RPC) protocol which uses XML to encode its calls and HTTP as a transport mechanism.(wikipedia) To start using XML-RPC in Java I used apache xml-rpc.

Example client and server XML-RPC.

Hi,

I was trying to access my back account but I could not due to problems with the java. Talking with a friend, he told me what i have to install to get it working. If you want to use Java in Ubuntu 64bits you have to use “sun-java-plugin”. To install it use this command:

sudo apt-get install sun-java6-plugin

See you,
Matheus

PS: Forgive me for publishing just a little. I was traveling and now I have some tests in university.
