[FIXED] Tomcat 9 Startup Order on Centos 7

Issue

I have five webapps which are starting at localhost:8080.

• l.war
• g.war
• w.war
• e.war
• r.war

All WAR files store in tomcat/webapps folder. I'm trying to change startup order like above because G app depends on L app. As I read tomcat starts up with alphabetical order and tomcat doesn't provide any sort of order. Some people could handle this with $CATALINA_BASE/conf/server.xml but They just do this for one application. I didn't see multiple context. So I tried;

1. Created context xmls in $CATALINA_BASE/conf/Catalina/localhost/ with the naming "l.xml, g.xml, w.xml, e.xml, r.xml".
2. Then I added below lines to $CATALINA_BASE/conf/server.xml

Content;

<Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true">
    <Context path="$CATALINA_BASE/webapps/l" docBase="$CATALINA_BASE/webapps/l.war"/>
    <Context path="$CATALINA_BASE/webapps/g" docBase="$CATALINA_BASE/webapps/g.war"/>
    <Context path="$CATALINA_BASE/webapps/w" docBase="$CATALINA_BASE/webapps/w.war"/>
    <Context path="$CATALINA_BASE/webapps/e" docBase="$CATALINA_BASE/webapps/e.war"/>
    <Context path="$CATALINA_BASE/webapps/r" docBase="$CATALINA_BASE/webapps/r.war"/>

I used absolute paths instead of $CATALINA_BASE. This caused some kind of recursive startup. How can i change the startup order of applications(without change their names)?

Solution

Tomcat comitter here, not possible. Tomcat does not guarantee any startup order. You will need to modify the default component for this.
