jmeter wont run !Not able to find Java executable or version. Please check your Java installation"

Question

I installed java from the offical java download page https://java.com/en/download/win10.jsp

It installed what appears to be a 32bit on my 64 bit system, which I can only guess is OK, as it did not present any other options.

I edited my system environtment variables, and added JAVA_HOME and added %JAVA_HOME%\bin to my "user variables" Path definition.

typing "set" in a cmd window produces:

JAVA_HOME=C:\Program Files (x86)\Java\jre1.8.0_151
:
Path=C:\ProgramData\Oracle\Java\javapath;C:\Program Files (x86)\Intel\iCLS Client\;C:\Program Files\Intel\iCLS Client\;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;.....C:\Program Files (x86)\Java\jre1.8.0_151\bin;

At the command prompt, "java -version"

produces:

java version "1.8.0_151"
Java(TM) SE Runtime Environment (build 1.8.0_151-b12)
Java HotSpot(TM) Client VM (build 25.151-b12, mixed mode)

But when I try to launch jmeter.bat, I get:

jmeter wont run !Not able to find Java executable or version. Please check your Java installation"

Any ideas?

Answer 1

1. If possible move your JRE to folder which doesn't have spaces in its path.
2. If for some reason it is not possible - surround path to "bin" folder of your JRE installation with quotation marks

3. In any case you should be able to run JMeter as:

   java -jar ApacheJMeter.jar
   

See Setting the JAVA_HOME Variable in Windows for more details.

I would strongly recommend switching to 64-bit server JRE as on 32-bit one you won't be able to allocate more than 4 GB to JMeter which might be not enough when it comes to high loads.

Answer 2

Your Java home is connected to JRE and not JDK (C:\Program Files (x86)\Java\jre1.8.0_151). See tutorial:

Windows: Set the environment variable JAVA_HOME to C:\Program Files\Java\jdk1.7.0_25

It should be connected to C:...\jdk[version] path, so set JAVA_HOME as:

set JAVA_HOME=C:\Program Files (x86)\Java\jdk1.8.0_151
