This question may be asked multiple times but I need latest update on this issue.
I am trying to configure a slave for my jenkins Master but getting following exception:
ERROR: Unexpected error in launching a slave. This is probably a bug in Jenkins.
java.lang.IllegalStateException: Connection is not established!

Any idea of what's the issue here?

I believe it needs to give more time for connecting but not sure, thanks in advance.
Well, Istio was blocking the connection to redis so created a service entry and it worked!

I am getting the below error when I create a new data source in WebLogic Server 12.2.1.3.0 after I installed the server today.
I have already created and tested the same in Java 1.7 using WebLogic Server 12.1.3.0.0.
This is failing now that I have updated to Java 1.8 using WebLogic 12.2.1.3.0.

I was working with local server, so everyday i have to start open fire for start chat.
so just open openfire with admin permission
means run as admin after that this problem will not arise
I am using Jmeter 2.8 and trying to do distributed (master-slave) testing for the first time.
I setup everything fine
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:
Request:

</userId><passwd><![CDATA[WillieWonka]]></passwd></credential>

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.
I have followed http://confluence.atlassian.com/display/CROWD/Creating+a+Connection+to+your+LDAP+Directory
for basic understanding and trying to set up LDAP for my office use.
scenario:
I have started Apache 2.2 (Apache Directory Server) at localhost:389 and it's running fine.
Next, I installed Apache DirectoryStudio and trying to create new connection. But I am getting the following error while opening the connection:
Error while opening connection - localhost:389; socket closed

I resolved this by changing theport numbers.

This means that your connection to the ldap server is wrong. I know the default username and password for Apache DS is admin and secret respectively.
Try the following as the bind DN or user string:
uid=admin,ou=system
