Re: [jetty-users] how to dynamically config jetty policy files?

[zhiwei chen <zhiweik@xxxxxxxxx>]

I mean, one app can read and write it's own directory .

When I add a new app, I want to add it's own directory and own policy in policy files.

for example:

I have 2 app,and two directory,like 

/webapps/app1.war

/webapps/app2.war

/read_write/app1/

/read_write/app2/

app1.war can only read and write /read_write/app1/ and app2.war can only read and write /read_write/app2/

I use policy file to realize this principle.

app1.policy file:

grant codeBase "file:/tmp/jetty-0.0.0.0-10000-app1.war-_app1-any-/-" {

   permission java.io.FilePermission "/read_write/app1/-", "read, write";

};

app2.policy file:

grant codeBase "file:/tmp/jetty-0.0.0.0-10000-app2.war-_app2-any-/-" {

   permission java.io.FilePermission "/read_write/app2/-", "read, write";

};

but when I add app3.war , I should add an app3.policy file like this:

app3.policy file:

grant codeBase "file:/tmp/jetty-0.0.0.0-10000-app3.war-_app3-any-/-" {

   permission java.io.FilePermission "/read_write/app3/-", "read, write";

};

How can I dynamically realize this? Should I modify jetty's source code?

BTW, what's the difference between java.io.tmpdir and jetty's work directory?

Thank you very much.

that would be my best guess as a solution...
