Could not find ApacheJmeter_core.jar

Getting the below response while running jmeter.server Batch file:
Could not find ApacheJmeter_core.jar ...
what to do now? I am using Java version-14

Could not find ApacheJmeter_core.jar ... meaning you haven't started Jmeter master.
But above error is different, in this case Jmeter slave cannot find rmi keystore file at bin folder thus throwing file not found exception for rmi_keystore.jks.
You have to generate rmi_keystore.jks by running create-rmi-keystore.bat for windows (for mac you have to run create-rmi-keystore.sh) then once .jks file is generated then copy it in bin folder of each Jmeter slave.
For more details, you can refer link: https://jmeter.apache.org/usermanual/remote-test.html#setup_ssl

cannot find org.neo4j.batchimport

I am continuing to have trouble with the import.bat file for the Neo4j batch importer. I started a new thread as the original problem was resolved.
from the command prompt I run
import.bat test.db sample\nodes.csv sample\rels.csv
With some variations on the path listing for the files, including absolute paths. I continue to get the following error message
The system cannot find the path specified.
Error: Could not find or load main class org.neo4j.batchimport.Importer
I also tried running import.sh from Cygwin and in my Debian VM but keep getting the error
Error: Could not find or load main class org.neo4j.batchimport.Importer
What am I doing wrong?

Please download the zip-file, not the github clone.
This is a pre-build binary as outlined in the readme, that doesn't require that you have to have maven installed to build it.

Why am I getting the error - load error: openssl -- java.lang.NoClassDefFoundError: Could not initialize class org.jruby.ext.openssl.ASN1?

I am trying to embed JRuby in a Java project. I am using jruby-complete-1.7.4.jar and ScriptingContainer.
For some reason, the following script throws error.
ScriptingContainer container = new ScriptingContainer();
container.runScriptlet("require 'net/https'");
This fails with the exception
load error: openssl -- java.lang.NoClassDefFoundError: Could not initialize class org.jruby.ext.openssl.ASN1.
This happens only in few computers. I don't have jruby-openssl and bouncy castle gem installed. My class path contains only jruby-complete-1.7.4.jar. I am wondering why this error happens and what should be done to work around this problem? How can this work on
a computer and fails on a different one? Any help to debug the issue would be great.
Jruby version - 1.7.4
System - Mac OS X 10.8.4

You do not need jruby-openssl separately .. it should be bundled with jruby jar.. make sure you do not have any old jruby-openssl or bouncycastle installed.

Jruby Applets: (LoadError) no such file to load

I'm currently having real problems trying to get the gem Nokogiri to work in my applet. I have the jruby-complete-1.7.3 jar and have attempted to install gems using the normal install line:
java -jar jruby-compelete-1.7.3.jar -S gem install nokogiri
And also I have tried the Gem-In-A-Jar method. At first it works fine, and allows me to eval ruby code and store the data returned. My problem arises when I add in the line:
require 'nokogiri'
While that line works fine in the irb, when trying to access it from the applet I get the following error:
classpath:/META-INF/jruby.home/lib/ruby/shared/rubygems.rb:396 warning: can't
canonicalize loaded names due to security restrictions; disabling
Message: (LoadError) no such file to load -- nokogiri
Stacktrace:
org.jruby.exceptions.RaiseException: (LoadError) no such file to load -- nokogiri

at RUBY.require(classpath:/META-INF/jruby.home/lib/ruby/shared/rubygems/custom_require.rb:36)
at RUBY.(root)(<script>:2)
I simply can't figure out why this exception is occuring. I've tried:
moving the gems manually into the "META-INF/jruby.home/lib/ruby/gems/shared" folder
I've added "require 'rubygems'" above the the nokogiri call.
Accessing the gems via the Gems-in-a-jar method: http://blog.nicksieger.com/articles/2009/01/10/jruby-1-1-6-gems-in-a-jar/
If anyone has an idea where I've gone wrong, or a solution to this issue, I'd greatly appreciate it.

Weird problem using sun.security.pkcs11.SunPKCS11: The specified procedure could not be found?

I'm developing this application to be used speceifically with Firefox (it's for internal use). Basically, we're using the sun.security stuff to read Firefox's KeyStore and sign data with the certs we get.
I've tested this on several machines and the results are varying, I can't seem to pinpoint the reason.
I've tested it on the latest ubuntu release, Firefox 3.6.13, using Java version 1.6.0_22, it works there. I also have a Windows XP laptop with the same Firefox version using Java version 1.6.0_17, where it works as well.
There are 2 other Windows XP laptops that it will not work on, giving the same error. They're running the same version of Firefox and using java version 1.6.0_17.
The error is:
java.security.ProviderException: Could not initialize NSS

Exception: java.security.ProviderException: Could not initialize NSS
From what I can tell it can't find the native nssLoadLibrary routine? The configuration file is pointing it to the Firefox install directory (where it can grab the nss3.dll or libnss3.so file). It does this across all pc's and all the paths in the configuration seem to be valid.
A sample config file, for what it's worth:
name=NSS
nssDbMode=readOnly
nssModule=keystore
nssSecmodDirectory="C:\\Documents and Settings\\user\\Application Data\\Mozilla\\firefox\\Profiles/8bzd2qqm.default"
nssLibraryDirectory=C:\Program Files\Mozilla Firefox
I was hoping someone would have a clue, or maybe some tips on getting further with debugging. I'm at a loss here.

I'm likely much too late for this to be of use to you, but I was having similar problems, and adding dist\WINXXX_DBG.OBJ\lib to my PATH resolved this issue.

Quick answer: Use the x86 jdk not the x64 jdk with NSS and JSS
Quick test against a NSS certificate database:
keytool -list -v -storetype pkcs11 -providerClass sun.security.pkcs11.SunPKCS11 -providerArg NSS_CONFIG_FIPS
where NSS_CONFIG_FIPS is the path to a config file pointing to an NSS database. This command will fail with a stack trace that matches the questioners error if it is a JDK issue and succeed if the JDK is configured properly (and if the config file is correct)
Note that my stack trace included the message:
Caused by: java.io.IOException: %1 is not a valid Win32 application.
I ran dumpbin /headers on the NSS dlls and found that the Mozilla built binaries are all 32 bit. I installed the x86 jdk and repointed JAVA_HOME. Everything began working.
To Vivek's point, NSS and the accompanying executables are very sensitive to the presence of the libraries. Be sure all of the .dll, .lib, and .chk files are present on the path. In particular, modutil.exe will fail certain commands without the chk files and the error messages are not helpful. Your NSS lib folder will need to include the NSS and NSPR lib folders, the jss4.dll and jss4.lib files, and the jss4.jar.
Also note that if you build NSS yourself, the libaries will not be signed with an approved code signing cert which will cause problems with JCA.
