Red5 1.0.6 warDeployer ClassNotFoundException FilterDef

[jeromeheissler]

Hi,

I would like to use the wardeployer to deploy my application. But when it parse my web.xml configuration it throw an exception :

If I unzip manually the war file, the application start normally. Does anyone know why it happens ?

[jeromeheissler]

I have the same issue with project oflaDemo from https://github.com/Red5/red5-examples. I do a mvn package then copy the war to the webapps directory and the war deployer throw the same exception :

For more information i'm working on a mac with java 1.8.0_60

[tyfly]

same error here with the oflaDemo.

Throws exception when i am going to install oflaDemo from the webpanel installer.

Tried all the other example apps. Can't get any of them properly installed. WebXMLParser throws SAXParseException on everyone of them.

red5 is installed on centos 7 with jdk 1.8.0_66.

I found the missing class in the regular tomcat archive; it is in the tomcat-util-scan.jar which is not part of the embeded package. You would be able to resolve this issue by adding the jar.

[The-Crocop]

added the jar - still not working

[mondain]

For all that have experienced this issue, does it only occur when the WarDeployer deploys your war, or does it happen every time your app starts up?

[The-Crocop]

happens when I build the war and then deploy it manually too

[tyfly]

It happens always when the WarDeployer deploys. This doesn't happen in 1.04.

[mikesheppard]

Same issue here. Worked in 1.0.4, testing 1.0.6 and experiencing this.

Any solutions?

[mondain]

Make sure you're using Spring 4.2.4; they fixed a classloader issue, it may be the same one we saw.

[mailsurfie]

tried the above provided methods, all failed. are there any other suggestions?

[mondain]

Is this still an issue with the latest 1.0.7-M8 release? I can't replicate the issue.

[mailsurfie]

Well, expecting stable release of 1.0.7, thanks a lot

[mondain]

1.0.7-M8 is looking pretty good in our testing so far over at Red5 Pro; All of these M8 pre-releases are helping us get to our actual release, which should be very soon.

[gongminrui]

This occurs at deployment time, as long as there will not be an exception after deploying start

Hi, I has had the same error. The Red5 server has started after that I deploy a war package. It's version 1.0.7 Release latest.

If I restart server, it's deploy ok.

I'm using Red5 version 1.0,5. It doesn't has that error.

I have had a solution. I only reset classLoader in EmbeddedTomcat class

Old code: public Context addWebapp(Host host, String contextPath, String docBase, ContextConfig config) { Context ctx = createContext(host, contextPath); ctx.setPath(contextPath); ctx.setDocBase(docBase); ctx.addLifecycleListener(new DefaultWebXmlListener()); ctx.setConfigFile(getWebappConfigFile(docBase, contextPath)); ctx.addLifecycleListener(config); config.setDefaultWebXml(noDefaultWebXmlPath()); if (host == null) { getHost().addChild(ctx); } else { host.addChild(ctx); } return ctx; }

New code:

public Context addWebapp(Host host, String contextPath, String docBase, ContextConfig config) { Context ctx = createContext(host, contextPath); ctx.setPath(contextPath); ctx.setDocBase(docBase); ctx.addLifecycleListener(new DefaultWebXmlListener()); ctx.setConfigFile(getWebappConfigFile(docBase, contextPath)); ctx.addLifecycleListener(config); config.setDefaultWebXml(noDefaultWebXmlPath()); if (host == null) { host = getHost(); } // reset ParentClassLoader if(!host.getParentClassLoader().equals(Thread.currentThread().getContextClassLoader())) { host.setParentClassLoader(Thread.currentThread().getContextClassLoader()); } host.addChild(ctx); return ctx; }

Rebuild red5 tomcat plugin and replace the old lib (red5-server\plugins\tomcatplugin-1.12.jar) And it work.

I built a file jar at: https://drive.google.com/file/d/0ByNfPmtze2FjWk1EQjJEaWM4dkk/view?usp=sharing

Thanks for the patch @ncdanh90 it'll be in tomcatplugin 1.14
