Today, I used his debugging tools in Dreamweaver, I found that I didn't debug it, and the following warning appeared.
Wait for the Dreamweaver debugger program to load, click OK after allowing the program to run. Finally, I got the clue from the console of the Java virtual machine, discovered that Dreamweaver was used to use a class file inside the Applet library inside the JDK, because the JDK was not set yet.
After setting JDK, the problem is solved, huh, huh, I thought it was the security issue inside IE. It didn't get it for a long time. It seems that Java's console has a certain use. Oh, some will be careful in the future.
