      Hi guys,

       

      I have an issue for infinispan session storage. Infinispan doesn't handle session storage in my basic configuration.

      I'm using the default standalone.xml configuration of JBoss EAP 7.0 :

       

      Here is the part from standalone.xml for infinispan :

      <subsystem xmlns="urn:jboss:domain:infinispan:4.0">
   <cache-container name="server" default-cache="default" module="org.wildfly.clustering.server">
   <local-cache name="default">
   <transaction mode="BATCH"/>
   </local-cache>
   </cache-container>
   <cache-container name="web" default-cache="passivation" module="org.wildfly.clustering.web.infinispan">
   <local-cache name="passivation">
   <locking isolation="REPEATABLE_READ"/>
   <transaction mode="BATCH"/>
   <file-store passivation="true" purge="false"/>
   </local-cache>
   <local-cache name="persistent">
   <locking isolation="REPEATABLE_READ"/>
   <transaction mode="BATCH"/>
   <file-store passivation="false" purge="false"/>
   </local-cache>
   </cache-container>
   <cache-container name="ejb" aliases="sfsb" default-cache="passivation" module="org.wildfly.clustering.ejb.infinispan">
   <local-cache name="passivation">
   <locking isolation="REPEATABLE_READ"/>
   <transaction mode="BATCH"/>
   <file-store passivation="true" purge="false"/>
   </local-cache>
   <local-cache name="persistent">
   <locking isolation="REPEATABLE_READ"/>
   <transaction mode="BATCH"/>
   <file-store passivation="false" purge="false"/>
   </local-cache>
   </cache-container>
   <cache-container name="hibernate" default-cache="local-query" module="org.hibernate.infinispan">
   <local-cache name="entity">
   <transaction mode="NON_XA"/>
   <eviction strategy="LRU" max-entries="10000"/>
   <expiration max-idle="100000"/>
   </local-cache>
   <local-cache name="local-query">
   <eviction strategy="LRU" max-entries="10000"/>
   <expiration max-idle="100000"/>
   </local-cache>
   <local-cache name="timestamps"/>
   </cache-container>
</subsystem>

       

      My web.xml :

      <!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >


<web-app>
  <display-name>Archetype Created Web Application</display-name>
   <distributable/>
</web-app>

       

      My jsp to put a new attribute to session :

      <html>
<body>
<h2>Set Current Time</h2>
<%
  System.out.println( "Putting date now" );
  session.setAttribute("current.time", new java.util.Date());
%>
The time is set to <%= session.getAttribute("current.time") %>
</body>
</html>

      And the one to get it :

      <html>
<body>
<h2>Get Time</h2>
<%@ page import="com.sample.PageBean"%>
<%
  System.out.println( "Getting date now" );
  PageBean pb = new PageBean();
%>
The time is <%= session.getAttribute("current.time") %>
<br /><%= pb.getCacheSize() %>
<br /><%= pb.getCacheContent() %>
</body>
</html>

      Finally, here is the bean to get infinispan web cache size and content :

      package com.sample;

import org.infinispan.Cache;
import org.infinispan.manager.EmbeddedCacheManager;

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;

public class PageBean {

  Cache<String, String> cache;

   public PageBean() throws NamingException {
  Context context = new InitialContext();
  EmbeddedCacheManager container = (EmbeddedCacheManager) context.lookup("java:jboss/infinispan/container/web");
   cache = container.getCache();
   cache.clear();
  }

   public int getCacheSize(){
   return cache.size();
  }

   public String getCacheContent(){
  StringBuffer sb = new StringBuffer();
   cache.entrySet().stream().forEach(cs -> sb.append("key: " + cs.getKey() + ", value: " + cs.getValue() + "<br />"));
   return sb.toString();
  }
}

       

       

      Is threre any configuration missing?

       

      Thank you for your help.

       

      Regards
