Hi everyone! I have a problem that I can't solve. I have two machines with hostname is "A" and "B". On A, I installed mySQL and create the database is "mydatabase" and two tables are "Roles" and "Users" Also on A, I installed JBoss Server (jboss-4.0.5.GA), and I select database is mysql. File "hsqldb.xml" has contents: ... | <jndi-name>DefaultDS</jndi-name> | <connection-url>jdbc:mysql://localhost:3306/mydatabase</connection-url> | <driver-class>com.mysql.jdbc.Driver</driver-class> | <user-name>root</user-name> | <password>abc123</password> | ... When I restart server on machine A, I see some messages: 10:43:02,109 INFO [WrapperDataSourceService] Bound ConnectionMana | :service=DataSourceBinding,name=DefaultDS' to JNDI name 'java:DefaultDS' On the B machine, I use Eclipse to create a EJB 3.0 project called "ActionBean". Then, I write three file ejb-jar.xml, jboss.xml and login-config.xml. They have some info important : ejb-jar.xml | ... | <enterprise-beans> | <session> | <ejb-name>ActionBean</ejb-name> | <resource-ref> | <res-ref-name>jdbc/DefaultDS</res-ref-name> | <res-type>javax.sql.DataSource</res-type> | <res-auth>Container</res-auth> | </resource-ref> | </session> | </enterprise-beans> | <assembly-descriptor> | <Security-role> | <role-name>doctor</role-name> | </Security-role> | <Security-role> | <role-name>nurse</role-name> | </Security-role> | <method-permission> | <role-name>doctor</role-name> | <method> | <ejb-name>ActionBean</ejb-name> | <method-name>getCallInfo</method-name> | </method> | </method-permission> | <method-permission> | <role-name>nurse</role-name> | <method> | <ejb-name>ActionBean</ejb-name> | <method-name>add</method-name> | </method> | </method-permission> | </assembly-descriptor> | ... jboss.xml | <security-domain>DB-Domain</security-domain> | <enterprise-beans> | <session> | <ejb-name>ActionBean</ejb-name> | <resource-ref> | <res-ref-name>jdbc/DefaultDS</res-ref-name> | <jndi-name>java:/DefaultDS</jndi-name> | </resource-ref> | </session> | </enterprise-beans> login-config.xml | <application-policy name="DB-Domain"> | <authentication> | <login-module code="org.jboss.security.auth.spi.DatabaseServerLoginModule" flag="required"> | <module-option name="dsJndiName">java:/DefaultDS</module-option> | <module-option name="principalsQuery"> | select passwd from Users where username=?</module-option> | <module-option name="rolesQuery"> | select Role from Roles where username=?</module-option> | </login-module> | </authentication> | </application-policy> Then, I pakage ActionBean and put three files (ejb-jar.xml,jboss.xml and login-config.xml) inside META-INF folder. JBoss server on the machine A inform all things ok! Also, on the machine B. I write the main class (client): LoginContext lc = new LoginContext("userTest", new ClientCallbackHandler());; | lc.login(); | InitialContext ctx = new InitialContext(); | ClientAction obj = (ClientAction)ctx.lookup("ActionBean/remote"); | try{ | System.out.println(obj.getCallInfo()); | //System.out.println(obj.add()); | | }catch(Exception e){ | System.out.println("You don't allow to do this method !"); | } | ... My auth.config: userTest { | org.jboss.security.ClientLoginModule required; | }; I imported package "jbossall-client.jar" and "jbosssx.jar". On the server(machine A), I also copied dirver "mysql-connector-java-3.1.14-bin.jar" inside \server\default\lib. Then, I run my main class and from console I enter username and passwd. But any informations that I entered can't call method on ActionBean (ex:obj.getCallInfo()). This mean is correct info can't call any method on ActionBean. Which wrongs ? mydatabase has two tables: CREATE TABLE Users(username VARCHAR(64) PRIMARY KEY, passwd VARCHAR(64)) | CREATE TABLE Roles(username VARCHAR(64), Role VARCHAR(32)) (I were writed a simple bean to access informations from mydatabase, all things ok). Please help me to solve my problem. Thanks. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4024119#...
