Sebastian, Your ClassNotFoundException is due to the package of your deployed Echo class not matching the ServiceClass package value in your services.xml.
-- WEB-INF > | |-- classes > | | `-- de > | | `-- hpfsc > | | |-- Echo.class vs <parameter name="ServiceClass">de.echo.Echo</parameter> So, the ServiceClass value should be: <parameter name="ServiceClass">de.hpfsc.Echo</parameter> There is no need to explicitly identify a class location, it just needs to be in the classpath of the web app (classes, web-inf/lib) or in the service aar file directly. Thanks, Ted -----Original Message----- From: keith chapman [mailto:[EMAIL PROTECTED] Sent: Sun 8/12/2007 9:58 AM To: [email protected] Subject: Re: Problems adding Axis2 to an existing Webapp Hi, In prder to validate ur services.xml you can use a tool hosted at http://tools.wso2.org:19762/wservices/AarValidatorXSL/ by WSO2. It consists of a tool to validate ur aar file as well. Thanks, Keith.
