JMeter 2.10 uses a new method for recording HTTPS requests when running under Java 7.
There have been some reports of problems starting the recorder, with errors such as the following:
ERROR - jmeter.protocol.http.proxy.ProxyControl: Could not initialise key store java.io.IOException: Cannot run program "keytool" (in directory "C:\apache-jmeter-2.10\bin"): CreateProcess error=2, The system cannot find the file specified
This means that the "keytool" application could not be found on the PATH. Please ensure that the PATH includes the bin directory for the appropriate Java installation.
If this was not correctly set when Java was installed, it may be necessary to update the script that starts JMeter.
For example add the following to jmeter.bat (Windows)
set JAVA_HOME=<path to JDK> rem for example set JAVA_HOME=C:\jdk1.7.0_45 set PATH=%JAVA_HOME%\bin;%PATH%
Similarly for Unix, update the script "jmeter" or "jmeter.sh":
JAVA_HOME=<PATH TO JDK> # for example JAVA_HOME=/usr/java170 export JAVA_HOME PATH=$JAVA_HOME/bin:$PATH export PATH
This should fix the problem. However note that the path will almost certainly have to be changed if a new version of Java is installed, so ideally the system PATH should be set to include the correct location for Java.
