My copy of GeoServer is showing an HTTP error 404 at start up. I can't figure out what's wrong and didn't find any useful help online either. Here is the log from GeoServer:

My configuration is the following:

  • GeoServer version 2.10.1 ("Mac OS X Installer")
  • Mac OS X 10.11.6 on a Macbook Air 11''
  • Java website says I have Java 8 update 111, java -version on Terminal says Java version 1.6.0_65

I tried to download the software again but the error persists.

  • That looks ok (those are warnings so you can ignore them) - what happens when you go to localhost:8080/geoserver ? – Ian Turton Jan 13 '17 at 14:22
  • There's an error 404 message: "Problem accessing /geoserver. Reason: Not Found" – jeremy g Jan 13 '17 at 14:36
  • can't tell what's up with just that part of the log – Ian Turton Jan 13 '17 at 15:12
  • I pasted the whole log here... – jeremy g Jan 13 '17 at 15:16

If you have java8 installed, which is a must have for this version of GeoServer 2.10.1. you need to tell Tomcat what version of Java it is looking for. Also I think your terminal should also give your some feedback that you are using Java8 version.

This is what I did in Tomcat v.7 in Linux:

`sudo nano /etc/default/tomcat7` 

Change line with JAVA_HOME to path where your Java8 is located. My was at:

JAVA_HOME=/usr/lib/jvm/java-8-oracle/jre
