In the world of mathematics real numbers have infinite precision and are therefore continuous and nonlossy. Floating-point numbers, which are used in computing, are limited with a finite precision and are not evenly spaced throughout their range. If don't keep this in mind you can get into many numerical blunders.
In the previous post I’ve told how to bill a customer with a minimal fuss. But oftentimes returning customers wish to add or change their billing information or maybe you want to delete the old ones. Let’s dive deeper and see what’s possible to do with Authorize.Net Customer Information Manager by remote procedure calls using, as previously, Java SDK.
Short Message Peer to Peer (SMPP) is an open, telecommunications industry protocol for exchanging text messages (SMS) between short message service centers (SMSC) and External Short Messaging Entities (ESMEs). The protocol is often used for connecting to SMS centers in order to send messages to mobile devices.
JIRA is a popular issue tracking and project management software. It can be used and accessed by lots of different means like IDE, email client or a web browser. Also there are many plug-ins for all sorts of other software products. Such an abundance is explained by the fact that JIRA has open and convenient remote procedure call APIs: REST, XML-RPC and SOAP.
So, it is possible to make your application communicate with JIRA through these APIs, too. If correctly integrate a Java API client, issuing a command to JIRA becomes the same as invoking a local subroutine. Let’s create such a little Java program and do some manipulations with an Issue in JIRA.
Today we’ll talk about writing java client for exchanging data with web service using SOAP protocol specification. Many of the web services that supports SOAP have java libraries that can make this task pretty simple to implement.
But if there is no such feature, then it becomes a little tricky, but in this article I will show you that it's not so hard as it seems.
Recently released Java 7 has a lot of useful API enhancements such as the automatic resource management, multi-catch statements, switch statement with strings, binary literals and improved numeric literals. This post is a quick roundup of the new features, which should help you to get a full picture of Java 7 syntax in a short time.
