I was debugging. I generated the war and I deployed it in the tomcat7 server but the exception is thrown too.
The broker is listenint ws and tcp transport. I tried to change the url connection using tcp instead ws and it works, but when I use the ws transport the exception is thrown. I'm using activemq 5.6.0 original libraries, inluding in the war (and in the eclipse porject too) these libraries: activemq-all-5.6.0.jar /lib/optional/activemq-optional-5.6.0.jar /lib/optional/commons-httpclient-3.1.jar /lib/optional/jetty-6.1.26.jar /lib/optional/jetty-util-6.1.26.jar /lib/optional/xstream-1.4.2.jar /lib/activemq-web-5.6.0.jar /lib/web/jetty-all-server-7.6.1.v20120215.jar /lib/web/jetty-websocket-7.6.1.v20120215.jar xstream-1.3.jar xpp3_min-1.1.4c.jar Need I some other libraries? -- View this message in context: http://activemq.2283324.n4.nabble.com/Could-not-create-Transport-Reason-java-io-IOException-createTransport-method-not-implemented-tp4678384p4678410.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
