Clustering JBoss 4.2.2 GA + Tomcat 6.0.20 + Struts 1.2.9
Hi All.
I want to welcome you in my first post in this forum.
I have this problem:
I've made an application in EJB 3.0 on Jboss + Struts Framework/spring on Tomcat.
Then I wanted to cluster jboss on two machines.
My laptop which has linux ubuntu on it, will hold jboss + tomcat.
My stationary Computer with Windows XP will hold second jboss.
I have some results:
The two jbosses log that there are others in cluster, but i get log message that there is no transaction manager lookup class defined.
I don;t know what to do.
Next thing is that my app is connectiing using spring:
<prop key="java.naming.factory.initial">org.jnp.interfaces.NamingContextFactory</prop>
<prop key="java.naming.factory.url.pkgs">org.jboss.naming:org.jnp.interfaces</prop>
<prop key="java.naming.provider.url">jnp://192.168.0.101:1100;jnp://192.168.0.1100</prop>
</util:properties>
When i was connection to localhost:1099 it was fine, but when I configure my app like the file above, i get connection refused.
Anyway, could someone provide me step by step what should I do to propably configure the cluster in this configuration: 1 tomcat and two jbosses.
My clases looks like this:
@Cache(usage = CacheConcurrencyStrategy.TRANSACTIONAL)
@Entity
@Table(name = "Users")
@SequenceGenerator(name = "UserSequence", initialValue = 0, allocationSize = 1, sequenceName = "UserSequence")
@NamedQueries(value = {
@NamedQuery(name = "loginQuery", query = "From User u LEFT JOIN FETCH u.role WHERE u.login = :login AND u.passwd = :passwd"),
@NamedQuery(name = "getAdminUserCount", query = "Select Count(u) From User u where login = \'admin\' "),
@NamedQuery(name = "getLoginCount", query = "Select Count(u) From User u Where u.login = :login AND u.passwd = :passwd"),
@NamedQuery(name = "getUsersWithPersonCountFiltered", query = "SELECT Count (u) FROM User u, Person p WHERE u.login like :login AND p.name like :name AND p.surname like :surname "),
@NamedQuery(name = "getUsersWithPersonFiltered", query = "Select DISTINCT u From User u, Person p, Role r WHERE u.login like :login AND p.name like :name AND p.surname like :surname "),
@NamedQuery(name = "getUserForPersonCount", query = "SELECT COUNT (u) FROM User u WHERE u.person = :person"),
@NamedQuery(name = "getUserForPerson", query = "SELECT u FROM User u WHERE u.person = :person"),
@NamedQuery(name = "getUserByIdCount", query = "SELECT Count(u) FROM User u WHERE u.userId = :id"),
@NamedQuery(name = "getUserById", query = "SELECT DISTINCT u FROM User u Left Join Fetch u.groups WHERE u.userId = :id"),
@NamedQuery(name = "getUserByLoginCount", query = "SELECT Count (u) FROM User u WHERE u.login = :login"),
@NamedQuery(name = "getUserByLogin", query = "FROM User WHERE login = :login") })
@NamedNativeQueries(value = { @NamedNativeQuery(name = "getUsersWithLessJobs", query = "SELECT role_id, user_id, Min(result) as min_jobs FROM (SELECT role_id, user_id, Count(processpathelement.*) as result FROM users left join processpathelement on responsible_user = user_id GROUP BY user_id, role_id)as result_table, role, users_bmsgroups WHERE role_id = roleid AND role_name <> 'CLIENT' AND user_id = groups AND users = :groupID GROUP BY user_id, role_id ORDER BY Min(result)", resultSetMapping = "getUsersWithLessJobsResult") })
@SqlResultSetMapping(name = "getUsersWithLessJobsResult", columns = {
@ColumnResult(name = "role_id"), @ColumnResult(name = "user_id"),
@ColumnResult(name = "min_jobs") })
public class User implements Serializable {
private static final long serialVersionUID = -1776171399753154200L;
private Long userId;
private Role role;
private String login;
private String passwd;
private String status;
//.....
And session beans:
@Stateless(name = "UserBean")
@Clustered
public class UserBean implements UserBeanRemote, UserBeanLocal {
And statefull
@Stateful
@Clustered
public class UserEditorBean implements UserEditorBeanRemote,
UserEditorBeanLocal
Please help me.
I've red the Jboss-4.2 clustering guide, but I don't understand some things.
Maybe someone have a tutorial or something?
I think that i could do some damage aerlier, so i want to know how make such cluster step by step.
Maybe i should install new jboss and strat over again?
