Could not publish to the server. java.lang.NullPointerException

错误信息:

publishing to tomcat v8.0 server at localhost has encontered a problem

Could not publish to the server. java.lang.NullPointerException

Could not publish to the server. java.lang.NullPointerException_第1张图片

产生错误的操作:

Could not publish to the server. java.lang.NullPointerException_第2张图片

解决方法:

1、找到Tomcat的配置文件“context.xml”,在Context标签中添加两个属性( reloadable=true” privileged=true”),如下图:

Could not publish to the server. java.lang.NullPointerException_第3张图片

2、加完保存之后,重新启动Eclipse,否则不生效。重新启动Eclipse之后,问题就解决了;但再查看Context.xml文件会发现两个属性又被去掉了。

其它方法

以下方法我没有实际测试过,如果你通过上面的方法不能解决问题,可以考虑尝试下面的方法:

解决方案:

  1. Removed the project from the workspace
  2. Remove .classpath, .project and .settings folder
  3. Reimport the project

Maven项目解决:

  1. Removed the project from the workspace
  2. CMD:mvn eclipse:clean
  3. Remove .settings folder
  4. CMD:mvn eclipse:eclipse
  5. Reimport the project
