When FreeMarker is used in a Java virtual machine with a
security manager installed, you have to grant it few permissions to
ensure it operates properly. Most notably, you need these entries to
your security policy file for
freemarker.jar:
grant codeBase "file:/path/to/freemarker.jar"
{
permission java.util.PropertyPermission "file.encoding", "read";
permission java.util.PropertyPermission "freemarker.*", "read";
} Additionally, if you are loading templates from a directory, you need to give FreeMarker permissions to read files from that directory using the following permission:
grant codeBase "file:/path/to/freemarker.jar"
{
...
permission java.io.FilePermission "/path/to/templates/-", "read";
} Finally, if you're just using the default template loading
mechanism which loads templates from the current directory, then
specify these permissions additionally: (note that the expression
${user.dir} will be evaluated at run time by the
policy interpreter, pretty much as if it were a FreeMarker
template)
grant codeBase "file:/path/to/freemarker.jar"
{
...
permission java.util.PropertyPermission "user.dir", "read";
permission java.io.FilePermission "${user.dir}/-", "read";
} Naturally, if you're running under Windows, use double backslash instead of a single slash for separating directory components in paths.
