我在 Linux Ubuntu 12.04 上使用 Netbeans 7.2.1,开发 Web 应用程序,使用 spring 3.1.0.RELEASE,spring 3.1.0。/ 休眠,mavenized。我使用公司私有 SVN 来访问这个项目。打开项目后,我使用 build with dependencies,然后清理并构建,然后在 apache-tomcat-7.0.41 上运行项目,然后在本文末尾出现异常。
我尝试了以下方法:
- 从 apache 取消部署项目,然后重新部署
- 重启tomcat
- 杀死tomcat进程
- 删除tomcat,然后重新下载并使用另一个目标文件夹
- 删除了 netbeans 缓存
- 在本地删除项目并重新连接到相同的 svn 并重新检查 svn。
- 删除本地maven存储库,重新下载jar,同样的异常!
- 在netbeans 7.3上尝试过,同样的问题发生了。
注意
- 同一个项目在另一台机器上“完美运行”!
- 这个问题发生在:
- 我从 SVN "A" 获得了网络应用 "X",我正在开发网络应用 "X",正在运行,一切都很完美。
- 我在同一个 SVN“A”上连接并获得了另一个网络应用程序“Y”,问题发生了,并且使用相同的步骤在另一台工作的机器上发生。
- webapp "y" 在某些工作机器上完美运行(也使用了 SVN 结帐)。
我只想知道这是什么问题,问题出在哪里。
