Hi Everyone,
Could someone please let me know how to programatically modify
the value of codeBase in the .java.policy file?
Specifically, please let me know if you are using a script at
installation time to modify the value for codeBase in the
.java.policy file or if/how you are doing this from your java
code on the database server (e.g. start up time, etc.).
To start up my RMI database server, I am using a .java.policy file with the following syntax generated from the policytool:
grant codeBase "file:/D:/SCJD_TimothyNguyen/*" {
permission ...;
permission ...;
At database server start-up time, I would like to
programatically check the value of an environment
variable called "SCJD_INSTALL_DIR" and then
replace the string:
in the .java.policy file with the following string:
"file:/<Value of SCJD_INSTALL_DIR environment variable>/*"
I have been thinking about writing a Windows install.bat
installation script (and the equivalaent UNIX install.sh
installation script) to:
1) Set the value for the SCJD_INSTALL_DIR environment variable
according to user input when the installation script is executed.
2) Read in this value and modify the value of the string
"file:/D:/SCJD_TimothyNguyen/*" in the .java.policy file.
Please let me know if this is a correct approach.
Lastly, please let me know how/if you are using the following
command-line arguments on your database server:
security manager policy file
Thank you for your help.
