Keytool is not recognized as an internal or external command

问题

I am trying to discover the list of trusted authorities in my Java Runtime using the instructions in this article. When I typed the command below:

C:\ColdFusion8\runtime\jre\lib>keytool -list -storepass changeit -noprompt -keystore

I got the following error:

'keytool' is not recognized as an internal or external command, operable program or batch file.

I checked that the directory containing my keytool executable is in the path. (On my Windows 7 machine, it's in C:\Program Files (x86)\Java\jre6\bin) Despite this, the command line will not recognise the keytool command.

I'm assuming that there are two separated commands mentioned in the doc:

C:\CFusionMX\runtime\jre\lib>keytool -list -storepass changeit -noprompt -keystore
C:\CFusionMX\runtime\jre\lib\security\cacerts

EDIT:

By the way can I use the following process instead of complex steps mentioned in the answer?

When I opened the WSDL into my browser, I saw the Lock icon, when I clicked on it a "Certificate" window opened
Then I clicked on "Install Certificate" option
A Certificate Import Wizard window opened, I clicked on Next I saw two options
- a) Automatically select the certificate store based on the type of certificate (this option was selected automatically)
- b) Place all certificates in the following store

I decided to select option (b), but I'm confused which certificate store I should select here.

You are getting that error because the keytool executable is under the bin directory, not the lib directory in your example. And you will need to add the location of your keystore as well in the command line. There is a pretty good reference to all of this here - Jrun Help / Import certificates | Certificate stores | ColdFusion

The default truststore is the JRE's cacerts file. This file is typically located in the following places:

Server Configuration:

cf_root/runtime/jre/lib/security/cacerts

Multiserver/J2EE on JRun 4 Configuration:

jrun_root/jre/lib/security/cacerts

Sun JDK installation:

jdk_root/jre/lib/security/cacerts

Consult documentation for other J2EE application servers and JVMs

The keytool is part of the Java SDK and can be found in the following places:

Server Configuration:

cf_root/runtime/bin/keytool

Multiserver/J2EE on JRun 4 Configuration:

jrun_root/jre/bin/keytool

Sun JDK installation:

jdk_root/bin/keytool

Consult documentation for other J2EE application servers and JVMs

So if you navigate to the directory where the keytool executable is located your command line would look something like this:

keytool -list -v -keystore JAVA_HOME\jre\lib\security\cacert -storepass changeit

You will need to supply pathing information depending on where you run the keytool command from and where your certificate file resides.

Also, be sure you are updating the correct cacerts file that ColdFusion is using. In case you have more than one JRE installed on that server. You can verify the JRE ColdFusion is using from the administrator under the 'System Information'. Look for the Java Home line.

Add your JDK's /bin folder to the PATH environmental variable. You can do this under System settings > Environmental variables, or via CLI:
```
set PATH=%PATH%;C:\Program Files\Java\jdk1.7.0_80\bin
```
Close and reopen your CLI window

Run the cmd as run as administrator this worked for me

回答4:

Execute following command:

set PATH="C:\Program Files (x86)\Java\jre7"

(whichever JRE exists in case of 64bit).

Because your Java Path is not set so you can just do this at command line and then execute the keytool import command.

I finally solved the problem!!! You should first set the jre path to system variables by navigating to::

control panel > System and Security > System > Advanced system settings

Under System variables click on new

Variable name: KEY_PATH
Variable value: C:\Program Files (x86)\Java\jre1.8.0_171\bin

Where Variable value should be the path to your JDK's bin folder.

Then open command prompt and Change directory to the same JDK's bin folder like this

C:\Program Files (x86)\Java\jre1.8.0_171\bin

then paste,

keytool -list -v -keystore "C:\Users\user\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

NOTE: People are confusing jre and jdk. All I did applied strictly to jre
