[JBoss-user] Error running example JMS
Hi!
I am having lots of problems running the examples of JMS of SUN. The error
is:
JNDI lookup
failed: javax.naming.NoInitialContextException: Need to specify class name in
environment or system property, or as an applet parameter, or in an application
resource file: java.naming.factory.initial
And the code
is:
/* * Create a JNDI
InitialContext object if none exists
yet.
*/ try {
jndiContext = new
InitialContext(); } catch
(NamingException e)
{
System.out.println("Could not create JNDI "
+
"context: " +
e.toString());
System.exit(1);
}
/* * Look up connection
factory and queue. If either
does * not exist,
exit.
*/ try
{
queueConnectionFactory =
(QueueConnectionFactory)
jndiContext.lookup("QueueConnectionFactory");
queue = (Queue)
jndiContext.lookup(queueName); }
catch (NamingException e)
{
System.out.println("JNDI lookup failed: "
+
e.toString());
System.exit(1);
}
In the command line:
"java SimpleQueueSender MyQueue 3"
And the
configuration is:
Classpath=.;j2ee.jar
JBoss 2.2.1
Jdk1.3
Does anybody know what is going on?
Thanks...
[JBoss-user] TimedOut connection
Hi, I have a connection time out problem. I am using jBoss 2.0 final, with a connection to an oracle DB. Whenever i run an sql statement which takes a few minutes, i can see in the log that the connection times out. No exception is thrown and nothing fails. Is seems as if the operation succeeded successfully but no results are shown in the DB as if the all transaction was not committed. I have tried changing a few of the entries in the jBoss.jcml, like setting the blocking to [true/false], the idle time out, the gc enabled but nothing affects this behavior. Thanks in advance for your help.

[JBoss-user] Apache + JBoss-Tomcat ?
Hello, Is is possible to use Apache + JBoss-Tomcat ? Tomcat is very easy to use with Apache, since Tomcat 3.2.1 will automatic produce a mod_jk.conf-auto when run Tomcat. So, I can easily include that configure file in apache configure(httpd.conf) . But when I run JBoss-Tomcat package, it will not produce that file. Since JBoss-Tomcat can auto deploy .ear, how can Apache know the new context ? Would you please to teach me if it is possible ?

Hi Pedro, I had a similar problem to the one you are facing. I wanted to generate a JSP page statically, and as a previous poster mentioned, you cannot do this without connecting to the webserver via HTTP. As an alternative to using XSL/XML, you could also use Velocity, http://jakarta.apache.org/velocity/ which allows for static page generation and variable substitution, etc. Also I was left with a nice user friendly template that could still be edited in a HTML editor.

RE: [JBoss-user] jBoss architecture question
Yes, you are quite right. However, we are, as you say stuck with whatever implementation is made by the JVM. Other than wrapping some native C code to handle signals and then communicate them to the java threads using some means, like sockets, there is nothing that can be done. It seems simple enough to test this on whatever implementation you happen to be on. Write a small program that spawns some threads, kill -TERM pid one of the threads and see what happens. Most likely you will have to do this for every VM and OS you routinely use. I know that we here have scripts that kill iPlanet threads automatically to keep the app server from dying, I do not know if these scripts are sending TERMs or KILLs though. This of course might work on a website where the only thing that is lost when the thread is killed is the request, it would not if there are interdependencies between threads.

No, it shouldn't and it won't. The java:/ context is only available within
the same JVM as JBoss. DataSources are not accessible remotely, in general,
because JDBC stuff is neither Serializable or Remote.

The client is not finding the RMI Registry Server because it assumes it is running on the same machine (127.0.0.1). You should be able to fix this by invoking the client with an explicit declaration of the hostname or IP address of the machine on which the RMI Registry Server is actually running, like this (all on one line): java -Djava.rmi.server.hostname=xxx.xxx.xxx.xxx -cp InterestClient where "xxx.xxx.xxx.xxx" is the IP address of the machine which hosts the RMI Registry Server in dotted-quad notation. Where the RMI Registry Server is actually running, by default it will install a TCP listener on port 1099. You should be able to see it: $ netstat -tan | grep 1099 tcp0 0 0.0.0.0:10990.0.0.0:* LISTEN This is actually a configurable system property; see: http://java.sun.com/products/jdk/1.2/docs/guide/rmi/faq.html#nethostname http://java.sun.com/j2se/1.3/docs/guide/rmi/faq.html#nethostname -- Mike On 2001-05-13 at 06:51 -, Kobi Schecider wrote: > I am new to JBoss and have been trying to get the interestclient example > running (the client and the EBJ running on different machines) without * * * > java -cp InterestClient > > Got context > javax.naming.CommunicationException [Root exception is > java.rmi.ConnectException: Connection refused to host: 127.0.0.1; nested > exception is: > java.net.ConnectException: Connection refused: no further information] > > My CLASSPATH is empty.

Re: [JBoss-user] Curious DataSource / Naming behavior
The servlet is executing within the same JVM and should share the same
namespace. The clients could be external to the JVM and hence fall over.
Think this is what is happening. You should be able to give just MySqlDB in
your lookup and it should work.

Re: [JBoss-user] Controlling whats in server.log
Believe the server log has output from all the Logger.log calls. If you don't want to log everything you could change the logging level to something like ERROR in the log4j.properties file.

[JBoss-user] Timed Out Connection
Problem Description : I am executing an SQL command which takes a few minutes and in the middle of the operation i am getting a connection time out event (which i can see on the log). I don't get any exception or indication something is wrong. The operation seems to end successfully but to the result in the DB, which does not exists. I tried changing the entries in the jBoss.jcml with all kinds of variations but it does seem to affect the nehavior of the server. I have tried to set GCEnabledto [true/false] , Idle Time out [true/false], but nothing helped.
