I use jprofiler 7.2.2, app server (JBoss) is running java 1.6.0_30. The same user is used to start JBoss and JProfiler.
I execute jpenable, choose offline mode, provide my setting file and then process fails with two different errors:

set Ip addresses in JMeter.properties
run Jmater-server.bat on all machines
but when I run test(a very simple request) it gets failed:

While server is up and running (I tested this request running from localMachine only, It is working fine).
What is wrong?
What I am missing?
I have resolved this issue, replaced
localhost:8080
with
computerName:8080
and start application server via start.bat instead run.bat
now it is working fine.
this is my first post
Hope will get solution.
I am getting below exceptions while starting glassfish server on solaris m/c and server is not starting.
After searching some of the blogs i found that it could be resolved by restarted m/c.
I want to find the cause...
Please help ...

Thanks and regards,
Ali
If you want to change the domain's ports without starting glassfish, you can do this by editing the xml domain's config file
domainName/config/domain.xml
Hope this will help you.
Good Luck
You should probably start by finding out what process is using port 3700 and find out if you can kill it.
If you cannot kill that process, you can use asadmin's create-domain subcommand to create a new domain that does not use the 'standard GlassFish ports'... The easiest way to do that is with the --portbase option.
I hosted a jsp service to access a java class to send a request to a server. I hosted this service in Tomcat 6.0 server hosted in my local computer and it worked fine. But when I tried it with another server which has Tomcat 5.5 I'm getting this error.
Error report is given below. I'll be really grateful if someone can help.

I solved this problem by installing Tomcat6 and uninstalling tomcat5.5. The problem was caused by the directories where we stored them and the java library path. They all have to be set properly. So apt-get installation is not advisable. Better download the tar and install it manually.
when i enter command ant reload the server generate eception.
I write the ant reload script in my buil.xml file.
But server could not reload it.
Exeption is

Based on the exception, it looks like ant could not connect(Connection refused) to your tomcat server.
Double check that tomcat has the manager webapp running and that ant is connecting with all of the correct information.
Tomcat, by default, does not have any manager web-app users enabled. You'll need to uncomment a user and give them a manager role in the tomcat-users.xml, found in $TOMCAT_HOME/conf.
That user, along with their password is then used by ant to connect to it.
