Error to access: http://localhost:8080/tomee/ejb

Hi.

I have the next error when I try to access to: http://localhost:8080/tomee/ejb

Sep 01, 2015 3:41:50 PM org.apache.openejb.server.ejbd.EjbDaemon service
WARNING: "null OEJP/4.6" FAIL "Unexpected error - Unable to read protocol version. Reached the end of the stream." - Debug for StackTrace

Somebody can help me? please!

Is this message from the server or from the client? What do the server's log files tell? Does the WebPortal work?

From server, the WebPortal doesn't work.

I try to access to: http://localhost:8080/tomee/ejb after that server starts sucessful:

OEJP is OpenEJB Enterprise Javabean Protocol (OEJP), but I don't know why it is Unable to read protocol version.

You can ignore this message, it's only warning after all. The parts relevant for the KNIME Server are in the localhost* files. Also the tomee-URL is not meant to be used in a browser, it's only for the connection between KNIME and the server (see also the installation manual).
