    copied!<p>I try to deploy a simple application in Scala using akka on Tomcat 7. </p> <p>In the first version, the actor system and the main actor were started directly from a Scala object. </p> <p>In the second version, I created an initializer (extending ServletContextListener) in order to start the actor system and the actor at the deployment of the war. </p> <p>In both case, I get a java.lang.LinkageError like the following :</p> <pre><code>java.lang.LinkageError: loader constraint violation: when resolving method "akka.actor.Props$.apply(Lscala/reflect/ClassManifest;)Lakka/actor/Props;" the class loader (instance of org/apache/catalina/loader/WebappClassLoader) of the current class, com/my-app/Transfert$, and the class loader (instance of org/apache/catalina/loader/StandardClassLoader) for resolved class, akka/actor/Props$, have different Class objects for the type scala/reflect/ClassManifest used in the signature com.my-app.Transfert$.&lt;init&gt;(Transfert.scala:14) com.my-app.Transfert$.&lt;clinit&gt;(Transfert.scala) com.my-app.Transfert.getState(Transfert.scala) org.apache.jsp.transfert_jsp._jspService(transfert_jsp.java:85) org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:70) javax.servlet.http.HttpServlet.service(HttpServlet.java:722) org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:433) org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:389) org.apache.jasper.servlet.JspServlet.service(JspServlet.java:333) javax.servlet.http.HttpServlet.service(HttpServlet.java:722) </code></pre> <p>I searched on Google and everywhere, but I didn't find a simple example of how to deploy a Scala/akka application on Tomcat 7 ?</p> <p>I know there was an akka.http package in akka 1.3, but I want to use akka 2.0 (at least). It seems akka.http has disappeared in favor of the use of play-mini. But I would prefer not to use play-mini or play. </p> <p>Is there any advice ? Any reading suggestion ? Or ??</p>
