  1. POJavax.enterprise.context.SessionsScoped behaving like Singleton in SpringContainer with JSF as frontend
    text
    copied!<p>I've Web App with front End JSF/RichFaces, Middle Tier Spring and Hibernate for DB. When I deployed the app and accessed from my system and my friends access, My friend could continue whatever the operation I had done(object was behaving as singleton/ applicationcontext). Below is the code of my session class, web.xml, faces-config.xml and spring.xml. I guess due to same reason I believe viewscoped bean is also not behaving to my expectation. Could somebody help in this case.</p> <pre><code>package org.kp.business; import java.io.Serializable; import java.util.ArrayList; import java.util.HashMap; import java.util.List; import java.util.Map;

oliDetails.initData(oliType); ArrayList&lt;OliData&gt; tempHolder = null; if(!oliTypesHolder.containsKey(oliType)) { tempHolder = new ArrayList&lt;OliData&gt;(); tempHolder.add(oliDetails); oliTypesHolder.put(oliType, tempHolder); }else{ tempHolder = oliTypesHolder.get(oliType); tempHolder.add(oliDetails); } } public void deleOli(int num, String oliType) { ArrayList&lt;OliData&gt; list = oliTypesHolder.get(oliType); if(null != list &amp;&amp;
