I’m trying to push stream from one application to another (let say from live to live2) in the same Wowza server. I’m receiving error
ERROR server comment 2015-08-19 19:34:16 - - - - - 3163.701 - - - - - - - - processNextRequest: error : java.lang.ClassCastException: com.wowza.wms.amf.AMFDataItem cannot be cast to com.wowza.wms.amf.AMFDataObj|at com.wowza.wms.amf.AMFDataObj.getObject(AMFDataObj.java:467)|at com.wowza.wms.pushpublish.protocol.rtmp.PushPublishRTMP$ConnectResult.onResult(PushPublishRTMP.java:1370)|at com.wowza.wms.netconnection.NetConnectionCallResults.handleResult(NetConnectionCallResults.java:95)|at com.wowza.wms.netconnection.NetConnectionProcessFunctions.processFunctions(NetConnectionProcessFunctions.java:65)|at com.wowza.wms.netconnection.NetConnectionProcessData.processNextRequest(NetConnectionProcessData.java:655)|

In previous version (3.5.2), it was working without problem.

Hi,
Can you provide some additional data about your setup?
Are you using Wowza Streaming Engine “[Stream Targets](https://www.wowza.com/docs/sample-map-file-entries-for-stream-target-destinations-push-publishing%28push-publishing%29)” feature?

Yes, I’m using Wowza Streaming Engine (4.2) with Stream Targets. I tried pushing stream with general RTMP or Another Wowza setup. No luck.

This is part of PushPublishMap.txt, but I configured with Wowza Manager
piotrg={“entryName”:“ppv\_testy”, “profile”:“rtmp”, “debugPackets”:“true”, “queryString”:“t=4964ccaf2b2d2b5b2ff02da48f2eec0f”, “streamName”:“ppv\_test”, “application”:“publishppv”, “sendFCPublish”:“false”, “debugLog”:“true”, “destinationName”:“wowzastreamingengine”, “host”:“[video.popler.tv](http://video.popler.tv)”, “connectionFlashVersion”:“FMLE/3.0 (compatible with FMSc/1.0)”}

Can you share with us the push publishing mapping which is configured for your stream from your application’s _PushPublishMap.txt_ file?
