一、问题描述
打开myclipse，发现server窗口报错，Could not create the view: An unexpected exception was thrown。
二、解决
这是由于之前被部署到tomcat中的项目被关闭，或者找不到导致的。我这里是之前把部署了的项目closed了，所以打开这几个项目就解决了这个问题。
三、拓展
D:install oolsmyeclipsemyeclipse10workspace.metadata.pluginsorg.eclipse.core.runtime.settings
打开这个文件，发现它记载着被部署的项目：
eclipse.preferences.version=1 tomcat6Server.JavaEE.IEARProjectName= tomcat6Server.JavaEE.altContextRoot= tomcat6Server.JavaEE.contextRoot=/JavaEE tomcat6Server.JavaEE.deployIsOverProject=false tomcat6Server.JavaEE.deploymentPath=D:\install\basic\tomcat\apache-tomcat-6.0.41\webapps\JavaEE tomcat6Server.JavaEE.isDeployed=true tomcat6Server.JavaEE.isExploded=true tomcat6Server.JavaEE.isUptoDate=true tomcat6Server.JavaEE.noFileCopy=false tomcat6Server.JavaEE.shouldBackup=false tomcat6Server.JavaEE.shouldOverwrite=false tomcat6Server.JavaEE.type=WebDeployment tomcat7Server.bspring.IEARProjectName= tomcat7Server.bspring.altContextRoot= tomcat7Server.bspring.contextRoot=/bspring tomcat7Server.bspring.deployIsOverProject=false tomcat7Server.bspring.deploymentPath=D:\install\basic\tomcat\apache-tomcat-7.0.55\webapps\bspring tomcat7Server.bspring.isDeployed=true tomcat7Server.bspring.isExploded=true tomcat7Server.bspring.isUptoDate=true tomcat7Server.bspring.noFileCopy=false tomcat7Server.bspring.shouldBackup=false tomcat7Server.bspring.shouldOverwrite=false tomcat7Server.bspring.type=WebDeployment
找不到里面记载的项目就会上面的错误。
