Is tcpmon, which comes with the JBoss tutorial, the correct

[raygardner]

When I startup tcpmon, it does not look anything like the tcpmon screen shot shown in Chapter 5 Section 5.4. Figure 5.1. (I'm not talking about the differences between Mac and Windows since the screen shot is obviously from a Mac.)

Perhaps tcpmon looks differently once it captures some network traffic, but I cannot get tcpmon to work so I have no idea if my version is correct or not.

Any help will be greatly appreciated!

I just tried it with 4.0.1sp1 and it looks right. You should get a configuration screen where you enter the port number. When you press add you should see a tab for your monitor. When you click on the tab, you will see the connection screen. If that's not what you get, perhaps you can describe what you do see.

If tcpmon is difficult for you, try turning up the log levels on org.jboss.axis. Either debug or trace level output should give you all the same information that tcpmon would give you, with a lot less configuration. When I update the getting started guide I will probably change the instructions to suggest this since it doesn't require any configuration beyond the log4j.xml file.

Thanks for the response!

I get the configuration screen. I fill in the 'Listen Port #' field to 7070 as instructed in the guide. But, when I click the 'Add' button nothing happens to the Swing GUI and I get the following exception in my startup command-window:

ant -f jboss-build.xml tcpmon
Buildfile: jboss-build.xml

I'm not sure how to tell but I do not think I'm using 4.0.1sp1. I believe I am only using 4.0.1. (Is there a difference?) However, I did download and install my JBoss instance earlier this week. Is there a way to determine if I'm using 4.0.1sp1? Here is my build information that gets printed during startup:

[Server] Release ID: JBoss [Zion] 4.0.1 (build: CVSTag=JBoss_4_0_1 date=200412230944)

By the way, I have tried turning up the log level on org.jboss.axis. I set it to DEBUG. (However, at the same time I also turned on org.jboss.webservice log level to DEBUG. Not sure if that caused a problem or not.) But, I did not see any extra output when I ran the WSClient. (I think I'll try it again without org.jboss.webservice. Plus, I'll try both DEBUG and TRACE this time.)

[norman.richards]

I've never seen that. I think I used RC1 for the getting started guide, but I can't imagine something like that suddenly failing in 4.0.1. Either way, if you are on 4.0.1, you should probably go to SP1. Without downloading it and trying it, it's hard to say.

Keep in mind that the console appender limits to INFO no matter what you set the category to. You will need to set the console appender level appropriately to see it on the screen or look to the server.log file, which isn't limited.

[raygardner]

I upgraded to 4.0.1sp1 but I still get the same exception and behavior when using tcpmon. (Same as noted in a previous post on this thread.)

I'd like to see it working and I'm sure it is just a small configuration issue that I don't have correct. (Although I have followed the Getting Started guide well, I just can't figure out what is wrong.)

I can run WSClient just fine when I point it to port 8080.

A previous post mentioned an RC1 version of the Getting Started guide. Where can I find that?

[raygardner]

I also changed the Consol Appender to DEBUG and then I was able to see the webservices output.

But, this extra output has not helped me figure out why tcpmon is not working.

Thanks for any help!

I have same problem with TCPmon. Following issue describe that error. Problem seems to be involved with JDK 1.5.x.

[jira] Created: (AXIS-1800) tcpmon AWT-EventQueue-0 bug in JDK1.5

dre pac (JIRA)
Wed, 02 Feb 2005 12:19:08 -0800

tcpmon AWT-EventQueue-0 bug in JDK1.5
-------------------------------------

Key: AXIS-1800
URL: http://issues.apache.org/jira/browse/AXIS-1800
Project: Axis
Type: Bug
Environment: JBoss 4.0.1 running on JDK 1.5.0_01
Reporter: dre pac


After running tcpmon ,when trying to push the "add" button to listen on port
8070 ,for example, I get a AWT-EventQueue-0 NullPointException instead of a new
tab for the selected port. This problem does not seem to occur when using JDK
1.4.2_07 which I am using as a temporary solution.
I have been trying to google this issue but not many people seem to have this
problem except those who tried ruuning tcpmon with JDK1.5. I find it really
strange since both axis and JDK1.5 have been around for quite a while now, and
what's even stranger is that not many people seem to use this combination.

below is the full stacktrace, please give us some feedback on when this issue
will be fixed, thanks.

I too am using JDK 1.5. I prefer to keep using JDK 1.5 but maybe I'll temporarily switch to JDK 1.4 just to see this tool work.

Thanks for the info!
