Could not publish server configuration for tomcat v8.0 server at localhost. multiple contexts

Image
Could not publish server configuration for tomcat v8.0 server at localhost.           multiple contexts containing same name /projectname The server.xml file is corrupted by Eclipse!!! I found out many times with Eclipse, don't be afraid to do some  changes in XML file. Inside the Eclipse we have Server folder. In that open the server.xml file. Just search your project name in the form of ['/Project Name']. Notice How many context tags are there in the same path? Remove the unwanted context tags.  Note:  [If there is three context tags with your project name then delete the two context tags and remaining one will remain there. ]

How do i Increase the capacity of the Eclipse Output console?

Image
Under Window > Preferences , go to the Run/Debug > Console section, then you should see an option "Limit console output." You can uncheck this or change the number in the "Console buffer size (characters)" text box below . ( This is in Galileo, Kepler, Juno, Luna, Mars and Helios CDT ). Here I shared some screen shot of the above                                               Window -->Preferences     Run/Debug --> Console   Uncheck the Limit Console Output. Then click the Apply button for the changes. Then click ok. Now your output console capacity is big to view your complete output.
