I am upgrading an application from JBoss 5.5 to Wildfly 16. This application was using org.jboss.cache.jmx.CacheJmxWrapperMBean. It kept the cache in a static org.jboss.cache.Cache and was accessed by a javax.servlet.Filter.

Since org.jboss.cache is not a part of Wildfly I am trying to change to use Infinispan. I have modified the Filter code to set in the cache as resource. However each time the Filter is hit, the Cache is a new instance, and what was put in cache previously is lost.

Would really appreciate how to tackle this!

The old JBoss code:

public class CacheManager {
private static Cache<String, Object> cache = null;

static
{
MBeanServer server = MBeanServerLocator.locateJBoss();
CacheJmxWrapperMBean<String, Object> cacheWrapper = (CacheJmxWrapperMBean<String, Object>) MBeanProxyExt.create(CacheJmxWrapperMBean.class,
"jboss.cache:service=MyService", server);
cache = cacheWrapper.getCache();
}

public static Object get(String node, String key) throws Exception
{
return cache.get(node, key);
}


public static void put(String node, String key, Object object) throws Exception
{
cache.put(node, key, object);
}
 }

                    <object-memory size="10000"/>

MyFilter, will sometimes put in Cache, and then other pages will get from cache.

public class MyFilter implements Filter {


   @Resource(name="infinispan/myCache")  Cache<String, MyObject> myCache;


   public void doFilter(ServletRequest request,     ServletResponse response,   FilterChain chain) throws java.io.IOException, ServletException   {
   
       HttpServletRequest hreq = (HttpServletRequest)request;
       HttpSession session = hreq.getSession(true);
    
       String servletPath = hreq.getServletPath();
       String key = getKey(request);
       if (servletPath.startsWith("myLogin")) {
            Object loginUser = getSessionInfo(request);
            this.myCache.put(key, loginUser);
            hresp.sendRedirect(hreq.getContextPath() + LOGIN_CONFIRM_PAGE);
        }
        Object obj = this.myCache.get(key);
        if (ojb == null) {
             session.invalidate();
        }
    }
  }
}
