Why does Tomcat require persistent MBeans
Hello, Just checked that not all of my mbeans are working under Tomcat 7. I exported all of them using /org.springframework.jmx.export.MBeanExporter/. I see exception when calling methods on some mbeans. The exception says /Problem invoking load. javax.management.MBeanException. Persistence not supported for this MBean/. I wonder why is it a strict requirement? I assume this is important because it can change some internal state of the object. Mine MBean is supposed to trigger data loading process, so I don't care about persisting the state. 1) Is there any way around it? 2) Why only part of my mbeans are functional inside Tomcat when they are exported in the same manner without additional configuration? Is there any standard for classes to be a valid MBeans under Tomcat?

Hi. I do not know either if the above is supposed to work also under Linux as a platform. It is not very clear in the Tomcat docs, and I have asked a couple of times on the list without getting much of an answer. (Probably because few people know). It should work but I haven't tested it. I suggest opening an enhancement request for the docs to be updated to include a known working Linux config. I should be able to take a look at doing that once I get back from ApacheCon next week.

requests die with a stack overflow
Hello all, I also posted this message to the Struts mailing list, because I'm not sure where the problem is. The version of Tomcat is 6.0.29, and the JVM is 1.6.0_17-b17 running on a Linux server, kernel version 2.6.18. The version of Struts is 1.3.10.

When the application starts behaving this way, all requests fail and they all generate those huge stack traces. The log file reaches 1 gigabyte in no time.

Re: requests die with a stack overflow
That forwarding to itself behavior has to be triggered under special circumstances because the application can work ok for long periods of time. But you're probably pointing me in the right direction because I have a base action class from which all other actions derive and in the base there is code to detect session timeouts (by comparing the requested session id with the current session id) and that code redirects to the home page action when a timeout is detected. That's probably when the looping is triggered somehow. I'll modify that base class and see what happens.

In the big scheme of things, from the above descriptions, I would tend to think that a session object is not something trivial, so creating one when you don't need it is probably indeed quite inefficient. (And then the session has to be stored somewhere, which will involve serialization, I/O etc..; and then some background task still has to periodically go clean up these useless sessions). From your description, it seems as if there are two types of usage of the same application : - a usage by real users, which does require a session - a usage as a web service, which does not require a session (because these are one-off calls, probably) I don't know Struts at all, but is it possible to distinguish the two types of usage, and bypass the getSession() call when the application is used as a web service ? Otherwise, would it be possible to set up two instances of your application ? Such as : /webapp1 : used by interactive users /webapp2 : used by web service clients and remove the getSession() call in the one used as a web service ?

Using EJBs deployed in JBoss from Tomcat
I am having issues trying to uses session beans deployed on JBoss 5.0.0CR1 server. I am tryingto access them from a stand alone Tomcat Server 6.0.16. The issue is that I am missing javax.ejb.Handle class. As far as I know it is part of ejb-api.jar. However I am unable to locate such a jar anywhere. Am I supposed to grab a javaee.jar, explode it, remover javax.servlet directory (so that there is no conflict with servlet-api.jar in Tomcat) debuild the jar and use it? Seems a little convoluted to me. If anyone has experience accessing JBoss deployed session EJBs from Tomcat I would really appraciate any pointers.

Log4J logging from server not working
I've been stuck with this problem for about a week now.
I am trying to get the Log4J working in my servlet. I have tried it on Tomcat
6.0.16 as well as Tomcat 5.5.26.
I have followed all the directions in the logging section for both versions.
The internal logging works fine in both cases. However, my servlet does not
produce any log at all. I must be doing something incorrectly, although I have
rechecked everything 100 times over. If anyone can help me I would really
appreciate it. Are the instructions for setting up logging complete?

Re: Log4J logging from server not working
Does anybody has any idea what might be causing the problem with Log4J? I've
googled for the longest time and there are no leads I found.

Subject: Log4J logging from server not working
I've been stuck with this problem for about a week now.
I am trying to get the Log4J working in my servlet. I have tried it on Tomcat
6.0.16 as well as Tomcat 5.5.26.
I have followed all the directions in the logging section for both versions.
The internal logging works fine in both cases. However, my servlet does not
produce any log at all. I must be doing something incorrectly, although I have
rechecked everything 100 times over. If anyone can help me I would really
appreciate it. Are the instructions for setting up logging complete?
Here is the description of my environment:
Windows environment (have superuser access).
JDK 1.6.0_07
Log4J 1.2.15
Here is also my log4j.properties that lives in WEB-INF/classes
log4j.rootLogger=DEBUG, R, stdout

Application versioning
I have multiple version of an application and i would like to switch from one to the other in a transparent way. This means that i would like to access it always through the same url ( localhost/myapp ), but pointing to myapp-1.1, or myapp-1.2 etc. etc. Thanks
JAAS Principal propagation from Tomcat to JBoss
I have the following situation (I try to simplify it):
1. I have a standalone Apache Tomcat server (5.5.26), on which is
running a web application:
- A Welcome jsp page (Welcome.jsp) and 2 Servlets: CalculatorServlet
and MyProtectedServlet
- The CalculatorSevlet servlet has to access remotly a stateless
session bean on a JBoss application server:
Properties env = new Properties();
env.put(Context.INITIAL_CONTEXT_FACTORY,
org.jnp.interfaces.NamingContextFactory);
env.put(Context.URL_PKG_PREFIXES, org.jnp.interfaces);
env.put(Context.PROVIDER_URL, localhost:1099);
Context c = new InitialContext(env);
MyCalculatorRemote calculator = c.lookup
(MyCalculatorBean/remote);
int result = calculator.sum(a, b);
1. I have a standalone JBoss server (version 4.2.2), on which is
running an EJB3 application
- A Stateless session bean (MyCalculatorBean), which exposes a sum(nt
a, int b) method through the remote interface:
@Stateless
@SecurityDomain(MyRealm)
public class MyCalculatorBean implements MyCalculatorRemote {
@RolesAllowed(math)
public Integer sum(int a, int b) {
return a + b;
}
}
- The Session bean is defined under the jboss security domain called
MyRealm, which is defined in the jboss login-config.xml and in fact
uses a MySql database for authentication and authorization:
application-policy name = MyRealm
authentication
login-module code =
org.jboss.security.auth.spi.DatabaseServerLoginModule flag = required
module-option name = debugtrue/module-option
module-option name =
dsJndiNamejava:/MysqlDS/module-option
module-option name = principalsQuerySELECT
PASSWORD FROM USERS WHERE EMAIL=?/module-option
module-option name = rolesQuerySELECT ROLE,
'Roles' FROM ROLES WHERE EMAIL=?/module-option
/login-module
/authentication
/application-policy
- The method sum(int a, int b) of the Session bean can be called only
by authenticated users with math role:
@RolesAllowed(math)
public Integer sum(int a, int b) {
return a + b;
}
Since the Session bean is secured with jboss security mechanism, which is
based on JAAS, to access the bean I have to setup JAAS authentication on the
web application (Single sign on authentication):
- I defined a JAASRealm in the Tomcat server.xml
Context path=/MyWebApplication docBase=/MyWebApplication
Resource name=jdbc/MyDB auth=Container type=
javax.sql.DataSource
maxActive=100 maxIdle=30 maxWait=1
username=root password=admin driverClassName=
org.gjt.mm.mysql.Driver
url=jdbc:mysql://localhost/mydb?autoReconnect=true/
Realm className=org.apache.catalina.realm.JAASRealm
appName=MyRealm
userClassNames=org.jboss.security.SimplePrincipal
roleClassNames=org.jboss.security.SimpleGroup
debug=99/
/Context
- I defined a login.config file to be used by the JAASRealm; the file
defines the login module to be used for jaas authentication and I define to
use the JBoss DatabaseServerLoginModule (I imported the jboss security
library into the tomcat common/lib folder):
MyRealm{
org.jboss.security.auth.spi.DatabaseServerLoginModulesufficient
debug=true
dsJndiName=java:comp/env/jdbc/MyDB
principalsQuery=select password from users where
email=?
rolesQuery=select role, 'Roles' from roles where
email=?;
};
- I set up Tomcat to specify the location of the login.config file,
changing the catalina.bat script:
set JAVA_OPTS=%JAVA_OPTS% -
Djava.security.auth.login.config==%CATALINA_HOME%/conf/login.config
- I set up the web.xml of my web application to define the login
configuration and the security constrains like follows:
security-constraint
display-nameConstraint/display-name
web-resource-collection
web-resource-nameProteced Servlet/web-resource-name
