I"m not sure exactly how is this supposed to work, but what does the jndi have to do with it? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4043068#4043068 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4043068

[JBoss Seam] - Re: Nested conversations and transaction management

by FabBoco

Christian, thank you for your explanations. I have some more questions: 1) Can you give me some reference to learn more about transactions that span HTTP requests ? 2) Can @Begin(flushMode=MANUAL) help me ? 3) Why seam has not options that let user manage the transactions as needed ? Am I using seam in the wrong way ? Regards Fab.

[EJB 3.0] - $Proxy146 cannot be cast to servlet... Access ejb bean from

by int2

Hi, Thank you for read my post, I'm new to ejb 3.0, there's a problem when I try to access an example session bean from servlet. Anyone please help :-) The code of the test session bean is: BLocal.java | import ...; | @Local | public interface BLocal{ | public String Say(String s); | } | BBean.java | import ... | | @Stateless | public class BBean implement BLocal{ | String Say(String s){ | return "hello " + s; | } | } | And the servlet, | Context ctx = new InitialContext(); | BLocal b = (BLocal)ctx.lookup("BBean/local"); | out.println(b.Say(" world")); | For the class Blocal in servlet, I just copy it from the session bean above (remove annotation) When I run the servlet, I get the result: | ype Exception report | | message | | description The server encountered an internal error () that prevented it from fulfilling this request. | | exception | | java.lang.ClassCastException: $Proxy146 cannot be cast to servlet.Bean1Local | servlet.S.processRequest(S.java:49) | servlet.S.doGet(S.java:70) | javax.servlet.http.HttpServlet.service(HttpServlet.java:697) | javax.servlet.http.HttpServlet.service(HttpServlet.java:810) | org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) | | note The full stack trace of the root cause is available in the Apache Tomcat/5.5.20 logs. | If the servlet and the session bean is inside an EAR, the servlet worked fine. But if the two project (servelet, session bean) deploy separately then I got the error above. Anyone can help ? Thank you a lot and regards Lee View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4043066#4043066 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4043066

[Security & JAAS/JBoss] - Re: Federated SSO Test Application Problem

by sohil.shah＠jboss.com

Andreas- This is most likely just the manner in which the binaries are packaged. 1) the jboss-sso.sar file contains the core sso engine 2) the federation-server.ear is a standalone web application that helps with secure sso token propgation across web domains. You may have to play around with the default packaging for this to run in an isolated class loading setup. Try packaging the federation-server.ear file inside the jboss-sso.sar file and removing the jboss-saml.jar and jboss-security-common.jar from the federation-server.ear file.

[Management, JMX/JBoss] - Programatically creating XMBean Instance

by toddjtidwell

I've developed an XMBean that works fine when deployed through a jboss-service.xml. However, I've come to a point where I would like to deploy multiple instances of this XMBean programatically. In the past, with a standard MBean, you'd do something like this: | ArrayList serverList = MBeanServerFactory.findMBeanServer(null); | | MBeanServer server = (MBeanServer) serverList.get(0); | | ObjectName on=new ObjectName("my.domain:service=Test"); | | ObjectInstance mbean = server.createMBean(MyMBean.class.getName(), on); | Sadly, with an XMBean the following Exception is thrown: | javax.management.NotCompliantMBeanException: Class does not expose a management interface: java.lang.Object | Obviously this is because I haven't tied it to the XML descriptor. Is there a way to programatically do this?

by joshuayeo

Hi all , I am using jdk 1.6.0_01 and jboss 4.0.5.GA. I have setup jndi lookup in my startup servlet init() method , however it did not lookup the jndi database name at all. It always give me error message cannot lookup the jndi name. Anyone have any ideas what is happening here ? Thanks Below is the startup servlet for my webapps: public class AdminStartupServlet extends HttpServlet { protected Logger logger = LoggerManager.getLogger(); public void init(ServletConfig config) throws ServletException { super.init(config); DatabaseAction databaseAction = ActionManager.getDatabaseAction(); try{ databaseAction.process(); } catch(NamingException ne){ ne.printStackTrace(); } catch(Exception ex){ ex.printStackTrace(); } } } This is DatabaseAction : public class DatabaseAction { protected DatabaseAction() { } public void process() throws Exception { try { OracleDatabaseManager.config(); } catch(Exception ex) { throw new Exception("Fail to config ORACLE database connection.", ex); } } } This is the Database Manager to lookup database jndi name public class OracleDatabaseManager { protected static DataSource oracleDS; public static synchronized void config() throws Exception { try{ InitialContext initialContext = new InitialContext(); oracleDS = (javax.sql.DataSource) initialContext.lookup("jdbc/OracleDS"); }catch(Exception ex){ ex.printStackTrace(); } } public static Connection getOracleConnection() throws Exception { try { //InitialContext initialContext = new InitialContext(); //oracleDS = (javax.sql.DataSource) //initialContext.lookup("jdbc/OracleDS"); return oracleDS.getConnection(); } catch (Exception ex) { throw new Exception(ex); } } } web.xml resource-ref tag <resource-ref> Oracle DB Connection <res-ref-name>jdbc/OracleDS</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> </resource-ref> jboss-web.xml tag <?xml version="1.0" encoding="UTF-8"?> <jboss-web> jboss.jca:service=LocalTxCM,name=jdbc/OracleDS <context-root>/</context-> <resource-ref> <res-ref-name>jdbc/OracleDS</res-ref-name> <res-type>javax.sql.DataSource</res-type> <jndi-name>jdbc/OracleDS</jndi-name> </resource-ref> </jboss-web> View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4043062#4043062 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4043062

[Beginners Corner] - Re: JVM Bind, port in use, but no application using it

by jboss newbee

Try to telnet to that port from command prompt as " telnet machineipaddress port#". If it opens a window then that port is used otherwise if you get not connected then it's not open. If nothing works then restart your computer and start jboss server first. Hope this helps!

[JBoss Seam] - Re: Persisting Object from previous screen in one trasaction

by shane.bryzak＠jboss.com

That exception indicates that your object is already persistent, but detached (unmanaged). You need to instead use merge.

[JBoss Seam] - Re: How to authenticate user by department?

by rmemoria

Why don't you implement a property called Department in your authenticator bean. Maybe it's easier. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4043057#4043057 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4043057
