Beginning with basic Java syntax and keywords, the fundamentals of Java are examined in a tour of the basics that is probably as good as any available--in that it mentions important object-oriented design principles early on without getting bogged down in jargon. The book also manages to integrate some Unified Modeling Language (UML)--particularly class diagrams--throughout, making this an up-to-date a

Since Google App Engine (GAE) announcement many developers are wondering when/if Google App Engine will support Java. As we already know GAE currently supports only Phyton. Do Java developers have to wait for Java support in GAE? In my opinion, no. Two parts screencast shows how to run GWT application on Google App Engine.Read more about this video…Want to control this feed contents? Sign up here and create your own feed!Want more on these topics?Browse the archive of posts filed under Web 2.0, AJAX, Google, Java, Python, Screencasts

The following documentation describes an integration scenario in which the business system, which is connected to the Integration Server by means of Java proxies, takes on the role of either a sender system (using client proxies) or a receiver system, or both. Use SAP systems based on Web AS 6.40 and higher are able to exchange data by using messages and HTTP. These systems can use Java proxies to connect to the Integration Server. SAP systems up to and including Release 4.6 are not able to exchange data by using messages and http. Such systems can only connect to the Integration Server by means of the IDoc adapter or the RFC adapter. To connect the platform-independent message interfaces, which are stored in the Integration Repository, to the Integration Server, use the Java proxy i

This is the Java version of the Binary Search program I had previously programmed using C++ (here). I’m absolutely new to java and made this with the help of All-in-one Desk Reference for Dummies (Required it especially for the input method) and my previous knowledge of functions (from C++). (If you want a properly indented, [...]

อีกเล่มนึงที่ผมได้ซื้อมาเพื่อใช้ในการทำงาน SOA ก็คือSOA Using Java(TM) Web Services เขียนโดย Mark D. Hansen2 เล่มก่อนที่ผมได้ review ไป (นาย Thomas และ For Dummies) จะเน้นแนวคิด (concept) เป็นส่วนใหญ่จะไม่ลงรายละเอียดในการพัฒนาและ coding มากนักซึ่ง SOA สามารถ implement ขึ้นมาด้วย platform ใดก็ได้ ทั้ง Java และ .NETส่วนงานที่ผมจำเป็นต้องใช้เป็น Java Platform ครับผมจึงเลือกเล่มนี้เพราะจะให้รายละเอียดที่ลงในส่วนการ coding ด้วยภาษา Java และ Web Servicesโด

Here is a tutorial to make your way into drawing graphics with Java. This program creates a semi-circle line of stars. The stars are randomly colored. I made the program using Netbeans 5.5, and I tested the code also with Sun Java Studio Enterprise 8.1. Both of them are free. The output is what you see above (star color may differ as they are randomly colored).import javax.swing.*;import java.awt.event.*;import java.awt.*;import java.awt.geom.*;class psy2k extends JFrame {public psy2k(){ super( "Psy2k star draw" ); setBackground( Color.white ); setSize( 400, 400 ); show();}public void paint( Graphics g ){ int xPoints[] = { 55, 67, 109, 73, 83, 55, 27, 37, 1, 43 }; int yPoints[] = { 0, 36, 36, 54, 96, 72, 96, 54, 36, 36 };Graphics2D g2d = ( Graphics2D ) g;GeneralPath star = new GeneralPath();star.moveTo( xPoints[ 0 ], yPoints[ 0 ] );for ( int k = 1; k < xPoints.length; k++ ) star.lineTo( xPoints[ k ], yPoints[ k ] ); star.closePath(); g2d.translate( 200, 200 )
