将项目导出到 jar 文件后，我的项目无法正常运行
After exporting project to jar file, my project is not fully working
我有一个问题，在 Eclipse 中，当我 运行 我的项目一切正常，但是当我最后导出它时 class 不想通过单击按钮打开。我在每个 class 中都使用数据库，并且我已经引用了库 (jcalendar-1.4)，如果它能帮助您解决问题的话。
登录和注册 class 工作正常，在登录并转移到 addActivity class 之后，大多数事情都在工作，比如将所有内容添加到数据库，但是那个按钮无法打开最后一个 class 应该显示所有添加的活动。
AddActivity class 的代码和在 jar 文件中不起作用的按钮称为 txtAddActivity

我有一个问题，在 Eclipse 中，当我 运行 我的项目一切正常，但是当我最后导出它时 class 不想通过单击按钮打开。我在每个 class 中都使用数据库，并且我已经引用了库 (jcalendar-1.4)，如果它能帮助您解决问题的话。 登录和注册 class 工作正常，在登录并转移到 addActivity class 之后，大多数事情都在工作，比如将所有内容添加到数据库，但是那个按钮无法打开最后一个 class 应该显示所有添加的活动。
