I’m attempting to attach a debugger with the eclipse wowza ide, but I cannot start wowza with xdebug. C:\Program Files (x86)\Wowza Media Systems\Wowza Streaming Engine 4.8.0\bin\>startup.bat Error occurred during initialization of VM Could not find agent library jdwp on the library path, with error: Can’t find dependent libraries Is there a workaround for this? I’m on windows 10 using this guide, [https://streamtoolbox.com/debugging-wowza-module](https://streamtoolbox.com/debugging-wowza-module). I’ve also tried adding the xdebug flag via the tune.xml file as VMOption -Xdebug -Xrunjdwp:transport=dt\_socket,server=y,suspend=n,address=1044 My Wowza streaming engine version is 4.8 ---

If this is about a development environment, what I usually do, is: (1) install Wowza on the dev machine (2) install Eclipse and the Wowza IDE for Eclipse (3) set up a debug configuration in Eclipse (menu “run” \> “debug configurations”) Now you can simply choose Run \> Debug (or F11) and you’ll run Wowza within Eclipse with full debugging You can also fill out the form at the bottom of that StreamToolbox page; maybe the author of that article has some ideas. ---

Hello I bumbed into the same issue and my eclipse debugger cannot connect to the wowza server (Failed to connect to remote VM. Connection refused. Connection refused: connect). Im assuming thats because Im missing something in the step 3 ( set up a debug configuration in Eclipse ). Which port should i use? Default is 8000, I`ve tried 8084, 8085, 1044, 8088, nothig works. Or is there something else you need to configure for debug to work? ---

@Bobbie_Mcneil, I don’t use Remote Debug, I’ve set up a Debug Configuration that runs Wowza Streaming Engine as a Java Application directly on the developer machine. Set the Main Class to `com.wowza.wms.bootstrap.Bootstrap`, and in the Arguments tab, set the Program Arguments to `start` and use the following VM arguments (instead of 2048M, you can choose to reserve more/less memory for the Java Heap), also the “native.base” is “win” because I’m on a Windows machine, as you probably understood. ``` -Xmx2048M -Dcom.wowza.wms.runmode="standalone" -Dcom.sun.management.jmxremote=true -Dcom.wowza.wms.native.base="win" ``` Under JRE, I use “Alternate JRE” and point to the JRE folder in the Wowza Installation folder. Tab “Dependencies” has 2 Classpath entries: The JRE System Library and wms-bootstrap.jar from Wowza’s /lib folder. Finally, on the Source tab, I add my current project so that I can debug its source code.
