Hi all,
I used Velocity as template engine but when I execute my application
it threw run-time security errors.
Here is my source:
------------------
public class velocity_tmpl extends HttpServlet{
public void doGet(HttpServletRequest req, HttpServletResponse res)
{
try {
Properties properties = new Properties();
properties.setProperty ("runtime.log.logsystem.class",
"org.apache.velocity.runtime.log.NullLogSystem");
properties.setProperty("file.resource.loader.path","../
velocity_example");
properties.setProperty("resource.loader", "file");
properties.setProperty
(
RuntimeConstants.RUNTIME_LOG_LOGSYSTEM_CLASS,"org.apache.velocity.runtime.log.Log4JLogChute"
);
Velocity.init(properties);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
VelocityContext context = new VelocityContext();
Template t = new Template();
context.put("name", "Velocity");
context.put("project", "Jakarta");
StringWriter w = new StringWriter();
try {
t = Velocity.getTemplate("template.vm");
//Velocity.mergeTemplate("template.vm", context, w);
//Velocity.mergeTemplate("template.vm", context, w );
t.merge(context, w);
} catch (ResourceNotFoundException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (ParseErrorException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (MethodInvocationException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (Exception e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
System.out.println("template: " + w);
}
}
------------------
and this is error:
------------------
[error] ResourceManager.getResource() load exception
access denied (java.io.FilePermission ..\velocity_example\template.vm
read)
java.security.AccessControlException: access denied
(java.io.FilePermission ..\velocity_example\template.vm read)
at java.security.AccessControlContext.checkPermission
(AccessControlContext.java:323)
------------------
Is it possible to solve this.
Thank all,
J
