[JCA/JBoss] - Re: Tests for db connection

by PeterJ

I had another thought. The issue appears to have something to do with timestamps assigned to stored procedures. All of the posts I have seen on this recommend recompiling the client code so that the client picks up the new timestamps. Well, in Java, I suspect that the Oracle JDBC driver loads the timestamps. If the Oracle JDBC driver provides a way to reload the timestamps, then if you wrote a valid-connection-checker-class-name class, you could have it make that Oracle JDBC driver call to reload the timestamps. So the question then becomes, does the Oracle JDBC driver provide such a feature?

Looking at the documentation on that Oracle error, it would appear that because of a database change that the current connection(s) are no longer valid and I guess that what you are looking for is some way of closing the existing connections and reestablishing them. I have seen requests for this reconnect capability before, but I do not think it is currently possibly. And to answer your specific question, using valid-connection-checker-class-name will not help you resolve this issue.

[Installation, Configuration & DEPLOYMENT] - Re: Error Shutdown JBoss 4 from MyEclipse

by PeterJ

But you said nothing has port 1099 open. If you did not change anything, then JBoss AS would have that port open. Also, when running netstat, use '-an', otherwise not all ports show up as numbers, in which case you could miss port 1099. Try running this (with JBoss AS up): netstat -abn | grep "java" That should show all ports open by JBoss AS. Also do this: get a JNDIView list and post the results.

[JCA/JBoss] - Re: Tests for db connection

by kejoseph

Thats for the reply Peter. My requirement is simple - I want the db connection to be tested by JBoss prior to handing it over to the application. This is easily achieved by the former check-valid-connection-sql statement. However, in certain cases (say Oracle package changed and JBoss start's receiving ORA-04062) we need to stop and start JBoss even with the above statement. I am wondering whether replacing it with valid-connection-checker-class-name will help resolve this issue and save us from a restart everytime something on Oracle side changes. Of course, I will try this out ; but wanted to understand the inner workings before blindly changing it. The documentation is not very detailed in this regard.

[Persistence, JBoss/CMP, Hibernate, Database] - Re: jboss deletes data from mysql db when it reboots

by PeterJ

Sounds like you are using Hibernate (JPA) to handle database access and that hibernate.hbm2ddl.auto is set to create or create-drop in the persistence.xml file.

With check-valid-connection-sql, you place a SQL statement in *-ds.xml and that statement is run. If there is no error, it is assumed that the connection is valid. With valid-connection-checker-class-name, you write a class that performs a connection check. This class can do anything. For example, it might query certain tables to ensure that the expected data exists, or perform a benign update to ensure that the account used has update right (or doesn't have update rights!) So the question is, would running a simple SQL statement be sufficient to verify the connection, or do you need to do something more complex?

[Installation, Configuration & DEPLOYMENT] - Re: jboss on mac 10.5.5: simple portlet helloworld..error 40

by PeterJ

Just because NetBeans lets you create a portlet does not mean that you can run it. Unless you have JBoss Portal installed, which is a portlet container, your portlet will not run. Also, if you are new to web application development, I recommend that you use a simple text editor to edit all files, both source and configuration, and use the command line to build and deploy the WAR file. At this point I do not know if the problem is with NetBeans or with JBoss AS, and because I don't use NetBeans I cannot tell you what buttons to push to get it to work. Unless you are willing to do things manually, I will not be able to help you (though someone with NetBeans experience is welcome to speak up).

[Management, JMX/JBoss] - method overloading issue in 4.2.2 ? Wrong target message. Wh

by jbosseron

I am trying to create a MBean and test in the JMX console. It deploys fine and shows up in the JMX console, but as soon as I call the method with no argument and later tries to call the method with an argument it fails with a "wrong target" error message. Is it a known issue or am I doing something wrong here? It works fine if I rename one of the methods so there is no overloading... I'm using 4.2.2.GA and JDK1.5.0_14 Here is test code that will break once jared up and deployed(2 files): //Test.java package test; public interface Test { public String aMethod(String aString); public String aMethod(); } //TestMBean.java package test; import org.jboss.annotation.ejb.Management; import org.jboss.annotation.ejb.Service; @Service(objectName="A:service=test") @Management(Test.class) public class TestMBean implements Test{ public String aMethod(String string) { return "Test with arg " +string; } public String aMethod() { return "Test with no arg"; } } View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4200838#4200838 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4200838
