I am trying to move all libraries out of my webapps directory, and into a
common place.
I have my libs that were bundled with tomcat in /tomcat/lib (the default),
and my extra libs i want to keep in /web/lib.
I've updated /tomcat/conf/catalina.properties to use the following:
common.loader=${catalina.base}/lib,${catalina.base}/lib/*.jar,/web/lib,/web/lib/*.jar
I have my database resource located in
/tomcat/conf/Catalina/localhost/myApp.xml (probably not relevant)
When I start tomcat, I get the errors listed below. However if I move
/web/lib/* to webapps/myApp/WEB_INF/lib/ it works fine.
What am I missing here?
Thanks,
Dan
First of all, don't do this.
Seriously, there are really no good reasons to do this and many, many
reasons not to.
Now, let's look at where you put your jars:
You said you put them in /web/lib - where is /web/lib located?
In the above catalina.properties line, you added:
/web/lib/*.jar
This is an absolute path, where /web is at the root of your file system.
I doubt you a) meant to put the JARs there, and b) have read permission
on that directory should it even exist. You have three options for
describing the directory location:
${property.name}/directory/. . . . ./*.jar
where property.name is either catalina.home or catalina.base.
some-other-directory/. . . ./*.jar
../some-other-directory/. . . ./*.jar
where the location is relative to catalina.base ($CATALINA_BASE).
/some-absolute-directory/path/*.jar
which just as it says, is an absolute directory path.
There may be other property.name(s) exposed - read the documentation.
Can you explain your use case for doing this? This will make a mess of
builds, and who knows what will happen if a developer uses a different
version of a library in a web application.
a) will it fail because the library operation is different?
b) will you get spurious class not found exceptions?
c) will the developer remember to leave some JARs out, but include ones
that you left out?
Inquiring minds really don't want to think about the above mess. I know
system administrators don't.
. . . . just my two cents.
