Hi All, I try to manage the Push Publish module with the new Streaming Engine 4.01, it’s not working and I can’t find what I’m doing wrong. The module is activated: > ModulePushPublish Wowza PushPublishing Module com.wowza.wms.pushpublish.module.ModulePushPublish I’ve configured my application to get the PushPublishMap file from the application folder and it’s working > 2014-03-20 14:13:00 UTC comment server INFO 200 - ModulePushPublish.loadMapFile: loaded map file (/usr/local/WowzaStreamingEngine/conf/live/PushPublishMap.txt): app: live/_definst_ After this line into the logs I find this error: **wowzastreamingengine\_error.log** > WARN server comment 2014-03-20 14:13:00 - - - - - 1627.857 - - - - - - - - ModulePushPublish.startPublishSession[live/_definst_/testipad][createClass]: Error creating push publishing implementation: com.wowza.wms.plugin.pushpublish.protocol.rtmp.PushPublisherRTMPProfileHandler: : java.lang.ClassNotFoundException: com.wowza.wms.plugin.pushpublish.protocol.rtmp.PushPublisherRTMPProfileHandler|at java.net.URLClassLoader$1.run(URLClassLoader.java:217)|at java.security.AccessController.doPrivileged(Native Method)|at java.net.URLClassLoader.findClass(URLClassLoader.java:205)|at java.lang.ClassLoader.loadClass(ClassLoader.java:323)|at java.lang.ClassLoader.loadClass(ClassLoader.java:268)| **wowzastreamingengine\_access.log** > 2014-03-20 14:13:00 UTC comment server WARN 200 - ModulePushPublish.startPublishSession[live/_definst_/testipad][createClass]: Error creating push publishing implementation: com.wowza.wms.plugin.pushpublish.protocol.rtmp.PushPublisherRTMPProfileHandler: : java.lang.ClassNotFoundException: com.wowza.wms.plugin.pushpublish.protocol.rtmp.PushPublisherRTMPProfileHandler|at java.net.URLClassLoader$1.run(URLClassLoader.java:217)|at java.security.AccessController.doPrivileged(Native Method)|at java.net.URLClassLoader.findClass(URLClassLoader.java:205)|at java.lang.ClassLoader.loadClass(ClassLoader.java:323)|at java.lang.ClassLoader.loadClass(ClassLoader.java:268) I can imagine there is a problem with Java but why? If anyone can help, thanks in advance. Best, Joffrey ---

Actually, it looks like you are using the Push Publish AddOn from Wowza 3. Please see this article to configure Push Publishing for Wowza 4: [How to push streams to CDNs and other services](https://www.wowza.com/docs/how-to-push-streams-to-cdns-and-other-services-push-publishing) Salvadore ---

I follow all the step and like the doc said: Starting with Wowza Streaming Engine 4, no additional installation steps are necessary. The Push Publishing AddOn has been updated and is now built in to Wowza Streaming Engine. I have updated a 3.6 version to a 4.01, I will try to start from a clean instance. Joffrey ---

A clean install do the job.
