MyEclipse+Tomcat部署项目时发生错误的几种问题

MyEclipse+Tomcat部署项目时发生错误的几种问题

一、项目部署不上

An existing resource has been found at location .........



二、项目部署上以后不能重新部署，而且已部署的项目无法移去

Manage Deployments

Deployment is out of date due to changes in the underlying project contents. You'll need to manually Redploy the project to update the deployed archive.



三、已部署的项目即删不出去，又重新部署不上





四、Eclipsse或MyEclipse在工作的时候无故退出

JVM terminated Exit code=1.....



原因和解决办法

Tomcat环境变量没有配置

在CLASSPATH中配置Tomcat环境变量

C:\Program Files\Apache Software Foundation\Tomcat 5.5\common\lib\jsp-api.jar;

C:\Program Files\Apache Software Foundation\Tomcat 5.5\common\lib\servlet-api.jar

最后所有问题就都解决了
