Can't add web project to Tomcat in STS

Trying to add a web project to a Tomcat instance.  The project has the Dynamic Web Module project facet enabled (Properties > Project Facets).  Still get this message:

Reason:

Grails project facet is not supported.  Need to use tc Server within STS.

Debugging Tomcat-hosted applications running outside of Eclipse/WTP

1. Execute Tomcat like so:  <Tomcat home>/bin/catalina.sh jpda start
2. By default (see catalina.sh contents), the JPDA address is 8000
3. In Eclipse, set up the following under Run > Debug Configurations > Remote Java Application:
   
   
4. Of course, browse to the web application project you want to debug.  
5. When you run this debug configuration, you will be able to step-through the code just as if you were running the web application inside Eclipse/WTP.  If necessary, add more projects under the Source tab.
   

Configuring Axis2 to expose web services over https

1. First configure Tomcat to handle https.  This link is useful for this but note for development purposes,when the keytool prompts for “Common Name (CN)”, enter “localhost”
2. Without further configuration, if you attempt to access your web service over https, you will likely get an error about "https is forbidden" thrown from the AxisServlet class
3. Next, configure Axis2 to accept https calls.  Edit the axis2.xml configuration file.  There should already be a section that looks like:
   

       <transportReceiver name="http"
                          class="org.apache.axis2.transport.http.SimpleHTTPServer">
       <parameter name="port">8080</parameter>
   

   Add another section like this:
   

       <transportReceiver name="https"
                          class="org.apache.axis2.transport.http.SimpleHTTPServer">
           <parameter name="port">8443</parameter>
       </transportReceiver>
   

   (Port may vary depending on your Tomcat configuration)
4. Without further configuration, if you try again, you will probably get an error about java.lang.NoClassDefFoundError: org/apache/http/HttpResponseFactory.  This interface can be found in the httpcore library.  If using Maven, include the following in your POM file:
   

           <dependency>
               <groupId>org.apache.httpcomponents</groupId>
               <artifactId>httpcore</artifactId>
               <version>4.0</version>
               <scope>runtime</scope>
           </dependency>
   

5. Now it should be working as it did over regular http
   

Tomcat installation changed, problems launching Tomcat in Eclipse

• Install location of Tomcat has changed.  Get message "The archive: [...]/apache-tomcat-6.0.20/bin/bootstrap.jar which is referenced by the classpath, does not exist." when attempting to launch Tomcat in Eclipse
• Fix: 
1. In Servers view, double-click on Tomcat server.  Overview of Tomcat settings appears.  
2. Click on "Open launch configuration"
3. Go to Classpath tab
4. Edit User Entries as appropriate
• If you haven't already, specify your Tomcat installation under Preferences > Server > Runtime Environments
