How To: Fix Eclipse Error "Tomcat Server Failed to Start"

 


This could be caused by a number of reasons.

The easiest attempt is to delete the Tomcat server (and remove its runtime from Eclipse settings).



Add back the server. Make sure that the Eclipse has got the right Tomcat server version in its list.

Choose the Tomcat server version in the list and let Eclipse download the version by itself.


If the problem persists, refer the following pages for a list of suggestions:

How To: Fix Eclipse Error "Java was started but returned exit code=14"?

 

.

When Eclipse runs for the first time, it may throw the following error message: 

"Java was started but returned exit code=14"

In one of the succeeding lines, it says:

"-Dosgi.requiredJavaVersion=11"


One of the possible causes is the different JRE or JDK (on the host platform) which does not meet the requirement of the Eclipse application. In this case, it requires version 11.


Solution: 

1) Exit Eclipse. Download Java JDK version 11, install and re-run Eclipse. 

2) Change Eclipse settings (Window -> Preferences -> Java -> Installed JRE's tab).


Note:

1) You may need to remove other JRE versions if they exist in Eclipse settings.

2) You may also encounter a warning message as follows:



3) Click on Compiler page link to reconfigure the compiler compliance level.
