list all active HTTP-Sessions
Hi,
I tried to view all acitve HTTP-Sessions. but I get an very strange error:
here is the code i used:
MBeanServer server = MBeanServerLocator.locateJBoss();
ObjectName oname = new ObjectName("jboss.web:type=Manager,path=/,host=localhost");
String sessionids = (String)server.invoke(oname, "listSessionIds", new Object[] {}, new String[] {});
StringTokenizer strtok = new StringTokenizer(sessionids, " ");
String description = "";
String sessionid = "";
while (strtok.hasMoreTokens()){
sessionid = strtok.nextToken();
String name = "pa_bean";
description += "ID: " + sessionid;
description += ", last accessed: " + server.invoke(oname, "getLastAccessedTime", new Object[] {sessionid.trim()}, new String[] {"java.lang.String"}).toString();
String param[] = {sessionid, name};
String signature[] = {"java.lang.String", "java.lang.String"};
PA_Bean pa_bean = (PA_Bean)server.invoke(oname, "getSessionAttribute", param, signature);
description += ", pa_bean: " + pa_bean;
}
logger.debug("desc: " + description);
}catch (Exception ex){logger.fatal(ex.getMessage(), ex);}the get last accessed time is working fine. just the getSessionAttribute results in the folllowing error:

the error occurs exactly in the line, where I invoke the getSessionAttribute.
can anyone help me with this problem?
best regards,
