How could LeanFT check licensing status, when JAR file is generated from a LeanFT project and executed without use of an IDE? In this case LeanFT runtime engine isn't started and URL of license server is not stored in jar file.
LeanFT is more than just that .jar file, and the engine logic takes place somewhere else. Roughly, LeanFT consists of two main parts:
LeanFT client
is the SDK with all the tests. In your case, a .jar file, but could've been a .cs or .js test and would have acted just the same.
has code like Browser.launch and Element.click.
these are commands that are sent to the LeanFT engine
LeanFT engine
among others, is a websocket server that listens to commands, interprets and executes them
The whole journey a command makes is roughly something as follows:
LFT.init is executed somewhere in the code.
It initiates the connection with the right socket server, configured either in a properties file (for java, it is leanft.properties file), or at runtime, via a configuration object (for java, it is a ModifiableSDKConfiguration object). Some minimal guidance regarding this configuration can be found here
this server can be on any computer on the accessible network, but the engine must be there too! (there are a lot of details regarding this here)
Without this command, the test will fail because any command (like click) can't execute as there is no WS connection
Element.click is executed somewhere later in the code
SDK constructs and sends a message to the engine (through websocket connection)
The engine checks if it has a valid license and if all good it performs the command.
Visualized, it is something like this:

When I run my server which is in websphere, it generates log file in "C:\Softwares\wlp\usr\servers\theory\logs\messages.logs".It has only theory.war in C:\Softwares\wlp\usr\servers\theory\dropins
When I place more than one war files such as theory.war, epic.war, success.war and execute the server it generates single log file in C:\Softwares\wlp\usr\servers\theory\logs\messages.logs
I have to generate separate log files for each war like :
C:\Softwares\wlp\usr\servers\theory\logs\theory.logs
C:\Softwares\wlp\usr\servers\theory\logs\epic.logs
C:\Softwares\wlp\usr\servers\theory\logs\success.logs
Im using util.logging package.
If you want to have separate logfiles you have to either write your custom FileHandler for JUL, or use 3rd party logging framework as Log4j for example.
You could also use binary logging , and then use binaryLog tool to filter messages for given app.
However, I'd STRONGLY recommend NOT doing all that, since in new apps that follow 12 factor principles should put all messages to standard out and standard error steams, what JUL by default does. This is used by containers, container orchestrators and logging infrastructure implemented there. Logging infa allows you to filter log messages based on various params without the need for separate log files. And if you have separate log files you will have to manually integrate that.
Recently i've came to an issue to configure Last Participant Support on deployed application. I've found some old post about that:
https://www.ibm.com/developerworks/community/forums/html/topic?id=77777777-0000-0000-0000-000014090728
On server itself i found how to do it. But with jython or wsadmin commands im not able to find how to do it on application itself.
But it does not help for me. Any ideas?
There is no command assistance available for the action of changing last participant support from the admin console which typically implies there is no scripting command associated the action. And there doesn't appear to be an wsadmin AdminApp command to modify the property. Looking at config repo changes made as a result of the admin console action, the IBM Programming Model Extensions (PME) deployment descriptor file "ibm-application-ext-pme.xmi" for an application is created/modified by the action.
If possible, the best long-term solution would be to use a tool like RAD to generate that extensions file when packaging the application because if you need to redeploy the app, your config changes wouldn't get overridden. If you can't mod the app, you can script the addition of an PME descriptor file in each of the desired apps with the knowledge that redeploying the app will overwrite your changes. The changes can be made by doing something along the lines of:
1) create a text file named ibm-application-ext-pme.xmi with contents similar to this:
<pmeext:PMEApplicationExtension xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:pmeext="http://www.ibm.com/websphere/appserver/schemas/5.0/pmeext.xmi" xmi:id="PMEApplicationExtension_1559836881290">
<lastParticipantSupportExtension xmi:id="LastParticipantSupportExtension_1559836881292" acceptHeuristicHazard="false"/>
</pmeext:PMEApplicationExtension>
2) in wsadmin or your jython script do the following (note in this example the xmi file you created is in the current directory, if not, include the full path to it in the createDocument command) :
deployUri = "cells/<your_cell_name>/applications/<your_app_name>.ear/deployments/<your_app_name>/META-INF/ibm-application-ext-pme.xmi"
AdminConfig.createDocument(deployUri, "ibm-application-ext-pme.xmi")
AdminConfig.save()
3) restart the server
My goal is to run a load test using 4 Azure servers as load generators and 1 Azure server to initiate the test and gather results. I had the distributed test running and I was getting good data. But today when I remote start the test 3 of the 4 load generators fail with all the http transactions erroring. The failed transactions log the following error:
Non HTTP response message: java.lang.ClassNotFoundException: org.apache.commons.logging.impl.Log4jFactory (Caused by java.lang.ClassNotFoundException: org.apache.commons.logging.impl.Log4jFactory)
I confirmed the presence of commons-logging-1.2.jar in the jmeter\lib folder on each machine.
To try to narrow down the issue I set up one Azure server to both initiate the load and run JMeter-server but this fails too. However, if I start the test from the JMeter UI on that same server the test runs OK. I think this rules out a problem in the script or a problem with the Azure machines talking to each other.
I also simplified my test plan down to where it only runs one simple http transaction and this still fails.
I've gone through all the basics: reinstalled jmeter, updated java to the latest version (1.8.0_111), updated the JAVA_HOME environment variable and backed out the most recent Microsoft Security update on the server. Any advice on how to pick this problem apart would be greatly appreciated.
I'm using JMeter 3.0r1743807 and Java 1.8
The Azure servers are running Windows Server 2008 R2
I did get a resolution to this problem. It turned out to be a conflict between some extraneous code in a jar file and a component of JMeter. It was “spooky” because something influenced the load order of referenced jar files and JMeter components.
I had included a jar file in my JMeter script using the “Add directory or jar to classpath” function in the Test Plan. This jar file has a piece of code I needed for my test along with many other components and one of those components, probably a similar logging function, conflicted with a logging function in JMeter. The problem was spooky; the test ran fine for months but started failing at the maximally inconvenient time. The problem was revealed by creating a very simple JMeter test that would load and run just fine. If I opened the simple test in JMeter then, without closing JMeter, opened my problem test, my problem test would not fail. If I reversed the order, opening the problem test followed by the simple test then the simple test would fail too. Given that the problem followed the order in which things loaded I started looking at the jar files and found my suspect.
When I built the script I left the jar file alone thinking that the functions I need might have dependencies to other pieces within the jar. Now that things are broken I need to find out if that is true and happily it is not. So, to fix the problem I changed the extension on my jar file to zip then edited it in 7-zip. I removed all the code except what I needed. I kept all the folders in the path to my needed code, I did this for two reasons; I did not have to update my code that called the functions and when I tried changing the path the functions did not work.
Next I changed the extension on the file back to jar and changed the reference in JMeter’s “Add directory or jar to classpath” function to point to the revised jar. I haven’t seen the failure since.
Many thanks to the folks who looked at this. I hope the resolution will help someone out.
I would like to create a utility to automatically copy files from one folder to another folder.

• The file type in (i.e. “.csv” or “.txt”) will also be specified as a parameter
How to pass parameters to windows service.. Please reply ..
Set your service to be a web service on some obscure port. Use a REST api (or whatever you like) to put a json/xml (or use get query strings if you like to) post to the service with directory, extension, and whatever else you might need.
The service has the data and can do its thing. You can also define other apis the web server can respond to which can stop the copy process or report status on ongoing copies (10 of 15 files copied, etc). You can enhance and augment it however you like.
am using liferay custom portlet and in that am using jasper report now my problem is that how can i download the pdf report directly on the client machine
right now am storing the file at server first.then provide url for downloading the pdf to user.but how can i directly store the file to client machine if i have pdf file's outputstream .
ot if i can know some how when user click on the download link and after downloading the file if i want to delete the donlowded file from the server then how can i do it.?if any one can guide me...
I'm not sure what you're asking for is possible, but I would be interested in seeing someone correct that statement though.
Servers really shouldn't be directly storing files on a client machine as that violates the intent of the client server relationship. A client has to make a request for the file and then the client can save that file (eg like a ftp download). Servers just don't manipulate client machines as they see fit.
As far as knowing when a file is downloaded, there isn't anything in a portlet you can do to detect that. You can use ResourceRequest and serveResource method to serve a file, but nothing in the portlet API will inform your portlet that the download is complete or that it wasn't interrupted by something.
As an alternative you might try simply having a cron job that will clean out old files. In this case, make sure to inform users how long they have to successfully download the file.
