Example 8 with ServletRequestListener

use of javax.servlet.ServletRequestListener in project tomee by apache.

the class HttpRequestImpl method init.

public void init() {
    if (begin != null && getAttribute("openejb_requestInitialized") == null) {
        // if called again we loose the request scope
        setAttribute("openejb_requestInitialized", "ok");
