从Eclipse中的项目中删除Apache TomCat运行时？

Question

I've got a project I've been building on Eclipse Ganymede targetted at tomcat 6.0, I've imported it into Europa and I need it to run on apache Tomcat 5.5

I can't find the reference to where the runtime is set to 6.0 to remove it. I've tried going to Windows > preferences > Server and I've installed the 5.5 runtime.

I can't however seem to find where the reference is to runtime 6.0 to remove it.

Any help would be appreciated.

Update:

I cant find any reference to Tomcat v6.0 in my build path, there is a reference to the servlet-api.jar of tomcat 5.5 though...

Answer 1

When Eclipse is up and running, choose preferences from the window menu. Choose from the bar on the left: Server, Runtime Environments.

Click the button Add, choose the version you want.

To remove the 6.0 reference, goto the libraries tab.

Answer 2

You can delete a Runtime easily from here, with no mess up:

Windows->Preferences->Server->Runtime Enviroments

Answer 3

I had a similar problem. I had a prject referring to a no more existing Tomcat instance. I was not able to remove Tomcat from "Server" and "Runtime Environments" from UI (delete button always gray),so I solved the problem deleting all the reference from the filesystem:

In project folder check files:

• .classpath
• .settings/org.eclipse.wst.common.project.facet.core.xml

In workspace folder check:

• .metadata.plugins\\org.eclipse.debug.core
• .metadata.plugins\\org.eclipse.wst.server.core
• .metadata.plugins\\org.eclipse.core.runtime.settings\\org.eclipse.jst.server.tomcat.core.prefs

Maybe a bit brutal but I didn't find a better solution.

Answer 4

This was tested over Eclipse Luna 4.4.2

In {workspace-directory}/.metadata/.plugins/org.eclipse.core.runtime/.settings. delete the following two files:

• org.eclipse.wst.server.core.prefs
• org.eclipse.jst.server.tomcat.core.prefs

Restart Eclipse

Answer 5

First, open the eclipse preferences,

then find the sever runtime environments,

you can now delete as you wish.

Answer 6

卸载项目并重新加载修复它...我喜欢Eclipse的人...

Answer 7

Delete the old server and add a new server. I had the same problem due to the fact that i changed the runtime environment to Java EE (for a webservice) and later had problems running my local apps. All i did was to delete and create a new server instance with apache runtime.

Answer 8

after removing the installed runtime from eclipse, do the following:

1] Close Eclipse

2] In {workspace-directory}/.metadata/.plugins/org.eclipse.core.runtime/.settings. delete the following two files:
    org.eclipse.wst.server.core.prefs
    org.eclipse.jst.server.tomcat.core.prefs

3] Restart Eclipse

Answer 9

Yep, I have eclipse Version: Indigo Service Release 2; Build id: 20120216-1857, unfortunately deleting the workspace solve the problem with having old Target Runtime. Don't forget to copy all your project work if there is no source control ;) ....

Answer 10

Open the Build Path and go to the Libraries tab. Remove the Apache Tomcat 6.0 library and add 5.5. This is the library that your project uses to build it self.

You can add new runtimes for running your project in the Servers view (Right-Click, Add new Server)

Answer 11

您也可以为此定义一个新服务器，并在那里指定它，也可以通过双击它来更改服务器配置，您将看到带有它的属性的窗口。
