How to CPU Profile Wildfly10 using VisualVM?

Problem:
I have an J2EE application that is running very slow for a given task (to generate some files) using a specific data set. I decided to run the visualvm profiler over the application to understand the nature of the problem. The application is running over Widlfly 10 using the latest Java 8.
To avoid configuration complexity, both profiler (visualvm) and Wildfly server are running locally.
The first problem met was the JVMTI error 62, that was resolved using the -Xverify:none as jvm parameter.
The second problem (the blocking one) is that if I run the profiler when the application is deployed and running, the Wildfly deployment scanner throws Exceptions like this one:

If I run the profiler without any deployed application, VisualVM's profiler starts without problems; however, if I tried to deploy my application under this state/operation mode, the wildfly scanner never starts and the application is never deployed.
So, What I'm doing wrong??

Finally, I put to work the visualVM Profiler... These are the steps that you need to do in order to execute a Wildfly 10 CPU profile using VisualVM (both executed locally!!):
Download the latest VisualVM (In my case was the version 1.4.1).
Download JDK10 ... You will need the JDK10 in order to run the VisualVM only. This step is required because of this bug (this was the bug that I was getting before when profiling the application)
Change the visualVM configuration file (<visual-vm>/etc/visualvm.conf) to point to your JDK10 installation...
Go to <visual-vm>/profiler/lib and copy the library: jfluid-server.jar into: <wildfly>/standalone/lib/ext ... This library is required to overcome the following error: java.lang.NoClassDefFoundError: org/netbeans/lib/profiler/server/ProfilerRuntimeCPUFullInstr (More about this error in here and here)
Next, modify the wildfly startup script to include the package org.netbeans.lib.profiler.server in the SystemProperty: jboss.modules.system.pkgs. Example: -Djboss.modules.system.pkgs=org.jboss.byteman,org.netbeans.lib.profiler.server. (According to this link, this property forces the wildfly to locate such package from any classloader)
Start the visualVM.
Start the wildfly server (including your application EAR/WAR/JAR application)... NOTE: I was running the wildfly server from Eclipse using JBoss Tools; under this configuration, my application (WAR) was in exploded mode!
Go to visualVM, open the org.jboss.modules.Main process. Then go to the profiler tab. Modify the target Profile classes and Outgoing calls and put the Classes that you want to monitor/profile (NOTE: For now, the winner configuration for me was: Profile classes: my.package.** and Include outgoing calls: my.package.**)
Hit the CPU Button, wait for the VisualVM to instrument your target classes and then invoke the code that is running slow; later, analyze the results...

Unable to to start Pentaho BI Server on Windows environment

I'm new to Pentaho BI Server. I've downloaded the community edition of Pentaho BI Server (biserver-ce-6.0.1.0-386), and I'm trying to run it on a Windows 10 (x64) machine. I've set "PENTAHO_JAVA_HOME" environmental path variable as suggested in http://akbarahmed.com/2012/05/12/install-pentaho-bi-server-4-5-on-windows-7-x64/ (this is for an older version of BI Server but I assume that the same method would be applicable here).
When I'm running start-pentaho.bat, this is the output I'm getting:
G:\Pentaho\biserver-ce-6.0.1.0-386\biserver-ce>start-pentaho.bat

A command prompt window briefly appears and then disappears. I am not getting any error messages thereafter, but if I visit http://localhost:8080, it seems that no server is listening on port 8080.
When I try to stop BI Server, this is what I'm getting:

Please let me know what I'm doing wrong and how to rectify the issue.

I got the very same behavior trying to start Pentaho BI server community edition version 5.3/JRE7 on AMD Athlon/Windows 10 Home (32-bit). The solution that worked for me was to start Tomcat as a Windows service, as follows:
(Note: The notes below assume that Pentaho BI Server was installed in C:\Pentaho)
Edit the system environment variables to include the following:
PENTAHO_JAVA_HOME = C:\Program Files\Java\jre7
If another application is using port 8080, edit the C:\Pentaho \biserver-ce\tomcat\conf\server.xml file to replace every occurrence of port 8080 with a new port number, e.g. 8081.
Using an Administrator Command Prompt, navigate to C:\Pentaho\biserver-ce\tomcat\bin and run the command:
service.bat install
(see https://tomcat.apache.org/tomcat-6.0-doc/windows-service-howto.html for further details).
At the same Administrator Command Prompt, run
tomcat6w.exe
to launch an application that allows you to startup and shutdown the service, and modify the service settings. The graphical user interface of the application opens.
In the application, modify the Tomcat settings as follows:
(a) Under the “Logging” tab, ensure that the logs sub-directory is under the tomcat directory -e.g.:
C:\Pentaho\biserver-ce\tomcat\logs
(b) Under the “Java” tab, append the following parameters under the existing lines in the “Java Options” text box (open C:\Pentaho\biserver-ce\start-pentaho.bat with a text editor and see the 32-bit and 64-bit processor settings – the ones below are for 32-bit processors):
-Xms256m
-Xmx768m
-XX:MaxPermSize=256m
-Dsun.rmi.dgc.client.gcInterval=3600000
-Dsun.rmi.dgc.server.gcInterval=3600000
(c) Under the “Startup” tab, ensure that the value in the “Working Path” text box points to the \tomcat\bin sub-directory - e.g.:
C:\Pentaho\biserver-ce\tomcat\bin
(see solution Pentaho Initialization Exception offered by Shivan on December 7, 2016 at for further details).
Under the “General” tab, click the “Start” button to startup Pentaho BI Server.
Using your web browser, launch the Pentaho BI server using the link http://localhost:8081/. The Pentaho login screen should appear at this point - it did for me.
After using Pentaho, you gracefully shutdown the Tomcat service by clicking on the “Stop” button.

SOLVED: I found out that the issue was due to an attempt to use a 32-bit Java. I came across this message,
WARNING [main] org.apache.catalina.core.AprLifecycleListener.init The APR based Apache Tomcat Native library failed to load. The error reported was [G:\Pentaho\biserver-ce-6.0.1.0-386\biserver-ce\tomcat\bin\tcnative-1.dll: Can't load AMD 64-bit .dll on a IA 32-bit platform]
Screenshot of Tomcat Console
I set the PENTAHO_JAVA_HOME environmental variable to point to a 64-bit JDK installed on my system, and now, Pentaho BI Server starts up as expected.

How to run selenium using other browsers?

I've configured the Selenium 2.0 IDE in Firefox and I execute my Project using this IDE.
Execute the Project using IDE.
And i Play back the executed screens.
Saved those Test case in HTML and Java format. (For Java: I used Jnit/Webdriver)
Then i open the java file using eclipse to change for Chrome Driver
After that i append this code into that System.setProperty();
Then i executed the Chromewebdriver using Command Prompt java -Dwebdriver.chrome.driver=/path/to/chromedriver -jar selenium-server-standalone-2.7.0.jar
Then i got the error as

How to solve this? So please try to configure and run the script through other browsers using webdriver concept.

It might be classpath issue....
Download the latest version of selenium, say 2.39.0 from the seleniumHQ.org site.
Place it in C:\ drive. Goto the environment variables and add java -jar selenium-server-standalone-2.39.0.jar to the classpath
