1. Initial status: the first installation is successful. An error will be reported after the second operation. An error occurred while calling the script that reported callscript error.
2. The. Class file before the basic class function (helpersuperclass) that I created was cleared and failed to be regenerated. In this case, you cannot modify or save the script. When the saved action triggers the helper class check, the system will prompt that this class does not exist.
3. Delete the project and re-import it. Check that the. Class file is reloaded.
The above problems are normal after the computer is restarted.
The second problem is the compatibility with the JDK version.
1. I re-install the pure XP in the Virtual Machine and directly install rft8.1 without installing any JDK. I use the built-in rft. After solving the above problems, it runs normally.
2. Some other colleagues' machines cannot run, so they are identified as environment problems. As suggested by colleagues, the problem is solved by the JDK version.
3. Uninstall jdk1.6, install 1.4, and set compiler under Java in Windows-perferences to 1.4. This is also true for the project. Log out, restart, and still report an error.
4. Check the environment configuration in the configuration. There are two Java environments: IBM, jdk1.4, and enable. Set 1.4 to disable. log out, restart, and report an error.
5. Uninstall jdk1.4 directly. The jdk1.4 option in the environment will be removed directly, deregistered, and run successfully.
Due to the limited level, you cannot identify the problem. You can only record your operations and Problem Discovery processes for your reference.
