更改Apache Tomcat中的站点级别配置

Question

I have build a rest service in Java. For that there is a configuration file that I have to place in /home/user1/ where user1 in the one where tomcat is running. If I change the path and move it to the /home/user1/workspace/myRest/ (it is eclipse workspace where I build project) then tomcat gave exception that file not found.

How do I inform tomcat that where you should look for the configuration file ? This file is being accessed by a jar in my project.

Answer 1

you can define a system varible when starting tomcat. and access it from your library.

for example inside your catalina.bat(on windows)/setenv.sh(linux)

windows

set JAVA_OPTS=%JAVA_OPTS% -Dconfig.path=%CATALINA_HOME%/{path to conf file}

linux

JAVA_OPTS="$JAVA_OPTS -Dconfig.path=$CATALINA_HOME/{path to conf file}"

then access it from your code

 System.getProperty("config.path")
