[appengine-java] Velocity Template reading error : java.security.AccessControlException: access denied (java.io.FilePermission

[vincwe]

Hi to all,
i'm try to use Apache velocity template for mailing,
using the following code

<code>
        VelocityEngine ve = new VelocityEngine();
        try {
            ve.setProperty("resource.loader", "file");
            ve.setProperty
("file.resource.loader.class","org.apache.velocity.runtime.resource.loader.FileResourceLoader");
                ve.setProperty("file.resource.loader.path","/template/email/");
                ve.setProperty( RuntimeConstants.RUNTIME_LOG_LOGSYSTEM_CLASS,
              "org.apache.velocity.runtime.log.Log4JLogChute" );

                 ve.setProperty("runtime.log.logsystem.log4j.logger",
                 log.getName());
                // ve.setApplicationAttribute
("javax.servlet.ServletContext",this.servlet.getServletContext());
                        ve.init();
                } catch (Exception e1) {
                        // TODO Auto-generated catch block
                    log.warning("EI:"+e1.getMessage());
                }

                VelocityContext context = new VelocityContext();
        Template template =  null;

                try
        {
                template = ve.getTemplate("mail1.vm");

        }
       .....

</code>

But at runtime gives this exception :

11-19 10:44AM 33.316 [wincheck123/4.337839622240022599].<stderr>:
[error] ResourceManager.getResource() load exception

(AccessControlContext.java:355)
..

Are there some security configuration to set for reading files on
appengine? such as security policy or others

Thank in advance
Regards
Vincenzo
