Logging error on WAR Deploy with Tomcat7, Apache Wink, and Mongo DB

Question

I am having problems deploying my application onto my tomcat server. I get the following trace every time I deploy it:

27-Oct-2013 17:02:34 org.apache.catalina.startup.HostConfig deployWAR
INFO: Deploying web application archive /var/lib/tomcat7/webapps/JsonTest.war
Handler error

Server context:

• Ubuntu 12.04.3 LTS 32-bit (I'll make it 64 later..)
• Tomcat 7 (only thing modified from stock install is adding users for manager[-gui])

• Java

   $ java -version java version "1.6.0_27" OpenJDK Runtime Environment (IcedTea6 1.12.6) (6b27-1.12.6-1ubuntu0.12.04.2) OpenJDK Client VM (build 20.0-b12, mixed mode, sharing) 

Application context:

I'm trying to convert the simple "books REST application" outlined here to use a Mongo connection. I have a feeling the Mongo part is irrelevant here. I'm also using Maven and Eclipse to deploy/build the project.

Some files:

I appreciate any help.

Answer 1

java.io.IOException: Couldn't get lock for %h/java%u.log

It looks like Tomcat does not have filesystem permissions to write to the log file. The %h variable is the value of the user.home system property, which is usually the home directory of the system user running the Tomcat process. Make sure that Tomcat has write permissions to that directory.

The location of that directoy can vary, but you can find it programmatically with:

System.getProperty("user.home")

You can also modify the default value by providing the argument -Duser.home=/your/path to the Tomcat startup script.
