Проблемы отладки Eclipse и GWT

Question

Я новичок в Java и GWT. Я следовал руководству по началу работы с Google по созданию приложения StockWatcher (http://code.google.com/webtoolkit/gettingstarted.html)) и столкнулось с препятствиями. Проект работает нормально, но когда я пытаюсь запустить его в режиме отладки, я получаю «Источник не найден» ошибка:

Я подумал, что это может быть проблема между компилятором и JDK. Я попытался изменить настройки, но на данный момент проблема не устранена. Пожалуйста, дайте мне знать, если мне нужно предоставить больше информации.

Answer 1

У вас есть двойные банки GWT в вашем пути к классу затмения.

Answer 2

При нацеливании на GWT вам нужно быть особенно осторожными, чтобы не обращался к классам, к которым у вас нет готового исходного кода в модуле GWT. Это связано с тем, как работает GWT - он компилирует в Javascript не файлы классов, а исходный код Java - и также выполняет оптимизацию всей программы, что означает, что все классы, которые могут использоваться в вашей программе, будут скомпилирован в JS (также означает, что динамическая загрузка классов невозможна).

То, что вы показываете здесь, является разборкой файла класса, соответствующего sun.misc.URLClassPath, и он примерно так же полезен для программы GWT, как велосипед для рыбы. Во-первых, GWT не имеет концепции ClassPath, учитывая, что весь код, используемый в модуле GWT, известен компилятору. Во-вторых, он находится в пакете sun.misc, для которого у вас почти наверняка нет исходного кода.

Учитывая последнее, что сообщение об ошибке понятно, однако эта ссылка указывает на то, что вы либо неправильно поняли GWT на глубоком уровне, либо что вы скопировали код из f.e. апплет.

Чтобы устранить эту ошибку, не указывайте этот класс.
