Java: A platform for platforms
Sun's reorg may seem promising to shareholders but it's also a scramble for position. The question now is whether Sun can,
or wants to, maintain its hold on Java technology. Especially with enterprise leaders like SpringSource and RedHat investing
heavily in Java's future as a platform for platforms

BAR CODE READER
Submitted by sree on Tue, 10/07/2008 - 03:42.
I Am a beginner working for the development of PoS system on java.We already developed some basic functionality and We created the application in Web Development platform using J2EE (JSP,Servlets, Apache Tomcat, MySQL).In this project we need to implement bar code and credit card processing. But discussing with some java experts we got to know that it is not possible to implement the above facilities in Web Applications. Now we are planning to convert it as JAVA SWING Application.Can any one guide me at this point.
My doubts are
1)Which one is better a swing application or web for bar code reading??
2)How can i implement bar code reader??

you can use an applet in
you can use an applet in your web application for bar code reading. You don't need to convert your whole system to swing base application. If more info provided I can do more help.
Barcode reader
You can use AJAX call to java api that can be linked to barcode reader API's that perform reading of barcode. We had used this technique to read barcodes and populate jsp form. barcode reading was done by vendor provided api
BAR CODE READER
hi sree,
Please don't change your web application to java swing application just for the two reasons you mentioned .Because you can implement both the things (bar code reader and accepting credit cards)easily with in a webapplication.Look at these links.
