A red warning is displayed after Tomcat is started.

After Tomcat is started, a red warning is displayed:

[Setpropertiesrule] {server/service/engine/host/context} setting property 'source' to 'org. Eclipse. JST. Jee. SERVER: webproject' did not find a matching property.

This is because in eclipse, when we deploy a web project through tomcat, Tomcat's configuration file server. XML will automatically generate a configuration information about the web project, similar to the following:

XML Code
View plaincopy to clipboardprint?
<Context docbase = "webpoject" Path = "/webproject" reloadable = "true" Source = "org. Eclipse. JST. Jee. SERVER: webproject"/>
<Context docbase = "webpoject" Path = "/webproject" reloadable = "true" Source = "org. Eclipse. JST. Jee. SERVER: webproject"/>
By default, the context element of server. XML does not support the attribute named source, so a warning is issued.

Solution: Disable tomcat, double-click the Tomcat server under eclipse, and find the server options option on the Tomcat server at localhost page, select the Options "Publish modual contexts to separat XML files", CTR + S, and start Tomcat

The following error occurs when Tomcat is started.

I found some information on the Internet:
This indicates that the APR is not found.
Brief solution: Go to the http://tomcat.heanet.ie/native/ to download the compiled tcnative-1.dll file, the latest 1.1.14, copy to JDK \ bin, and then start it to load the APR.

 

Error message:

Warning a docbase E:/tomcat/webapps/lovemu inside the host appbase has been specified, and will be ignored

When eclipse Galileo is upgraded to Indigo and the project is released to Tomcat, the following warning is prompted:
Warning a docbase D: \ apache-Tomcat-6.0.26 \ webapps \ projectname inside the host appbase has been specified, and will be ignored

This project cannot be accessed.
The returned result uses Galileo.
Check it online. It seems to be a folder with the same name in D: \ apache-Tomcat-6.0.26 \ work \ Catalina \ localhost. Delete the folder and try again. The problem persists.

It seems that two versions of eclipse have different actions to process the same tomcat configuration.
I tried to call several Tomcat server parameters. Sure enough, if you hook up the serve modules without publishing under server options, everything is normal.

 

Let's take a look at the experience of our predecessors.
