Teach you how to start Java swing's first embedded web

1. I found an open-source project djproject, which is embedded with a browser in swing. It can execute simple JavaScript code in the browser and play other functions such as flash. For some source code, download http://gongqi.iteye.com/blog/754231.

2. To begin.

3. Copy a demo on the Internet and test it. The plug-in package DJNativeSwing-SWT.jar and djnativeswing. Jar need to be introduced

An error occurred while running.

Http://ishare.iask.sina.com.cn/download/explain.php? Fileid = 20122660 download the SWT. jar package and introduce it to eclipse.

Search online and find the region.

There is an answer from the original provider of djnativeswing.

According to his answer, it means that the introduced SWT package requires version 3.7m5 and later.

4. Therefore, go to http://www.java2s.com/code/jar/s/swt.htmand there are different regions on the network, different system swtpackets,

Download the 3.7m7 SWT. jar package on this website and introduce it to eclipse.

5. Run the program. Binggo. Successful.

The result is as follows:
