Problems about the j2_plug-in eclipse

Midlet2.0 Program, Sometimes appears

** Error installing Suite (39): The Jad matches a version of a suite already installed.

Execution completed. Error

I checked a lot of information, some said that I had to reinstall it, some said that I had to switch defacolorcolorphone, defaultgrayphone, mediacontrolskin, and qwertydevice. But now I have four problems. What should I do? Reinstall? Sorry!

After carefully studying the wtk file, we found that there was an appdb, which contains the defacolorcolorphone, defaultgrayphone, mediacontrolskin, and qwertydevice folders. Each folder contains files not found with the project name, for example, # MIDlet % 0020 # suite % 0020 # vendor _ # My # project % 0020 # MIDlet % 0020 # suite_suite. *, so I did not continue to delete it directly. In addition, I found another name: suites. the UTF file also stores information about my projects, such as # MIDlet % 0020 # suite % 0020 # vendor _ # My # project % 0020 # MIDlet % 0020 # suite _, there are a few garbled characters in the front, which are also deleted, and then you can run your program again?

Error installing Suite (39): The Jad matches a version of a suite already installed. Isn't it? Haha, you're done!

Later, I compared it carefully and found that it was actually caused by the exception of the program running, which will be in the suites. the UTF record indicates that the suite has been loaded, but it is not normal. You only need to follow the above method to solve the problem.

I don't know if there is any better way. Please join us! Thank you!
