springred5beancreationexception

Red5 application is getting BeanCreationException when ran as a Windows service

I have a Red5 application that runs fine in Eclipse. But when I build the app and try to run it as a Windows service I am getting an error.

After the app starts, when it tries to start the Red5 server I get the following error/stack trace:

My relevant code is as follows:

    // get current loader
    logDebug("   about to get baseLoader");
    ClassLoader baseLoader = Thread.currentThread().getContextClassLoader();
    // build a ClassLoader
    logDebug("   about to get loader: " + baseLoader);
    ClassLoader loader = ClassLoaderBuilder.build();
    // set new loader as the loader for this thread
    logDebug("   about to set new loader:" + loader);
    Thread.currentThread().setContextClassLoader(loader);
    // create a new instance of this class using new classloader
    logDebug("   about to create boot object: " + loader);
    Object boot = Class.forName("org.red5.server.Launcher", true, loader).newInstance();
    logDebug("   about to get method 1: " + boot);
    Method m1 = boot.getClass().getMethod("launch", (Class[]) null);
    logDebug("   about to invoke method 1: " + m1);
    m1.invoke(boot, (Object[]) null);   
    // not that it matters, but set it back to the original loader
    logDebug("   about to set original loader: " + m1);
    Thread.currentThread().setContextClassLoader(baseLoader);

Any ideas what is causing the error and how to fix it?

EDIT:

I added a system property called red5.root set to the Red5 root directory as shown below and it got rid of the nullPointerException I was having above.

String red5Root = serverHome + "/red5-server-1.0.6-RELEASE";
System.setProperty("red5.root", red5Root);

However I am still having a problem connecting to the red5 server. When I try to go to access my web app with the following url:

localhost:8080/streaming/streaming.html

I am getting a 500 error with this exception:

java.lang.NullPointerException org.red5.logging.LoggerContextFilter.doFilter(LoggerContextFilter.java:64)

What could be causing this NullPointerExeption?

Solution

  • Since the first question is already kind of answered in the edit I will just answer the second question.

    The NPE was happening because of conflicting logging jars in the classpath. I was able to solve the problem by removing the following from my webapps/myApp/WEB-INF/web.xml file.

     <filter>
     <filter-name>LoggerContextFilter</filter-name>
     <filter-class>org.red5.logging.LoggerContextFilter</filter-class>
 </filter>

 <filter-mapping>
     <filter-name>LoggerContextFilter</filter-name>
     <url-pattern>/*</url-pattern>
 </filter-mapping>
