Where is the Eclipse Java home directory?

Question

Im trying to install pydev using the official tutorial My issue is that i can not locate my java.home directory. I have checked Applications/eclipse to no avail.

The second step is discovering the java being used in Eclipse: go to Help > About > Installation details and look for 'java.home'

Then to actually import it, in the command line, go to the Eclipse 'java.home' directory and execute

bin/keytool.exe -import -file pydev_certificate.cer -keystore lib/security/cacerts

Can anyone tell me the path to this? what am i missing?

Thanks

Answer 1

Go to Help menu-> About submenu -> Installation Details button -> Configuration tab. Find the java.home configuration setting in the text area. Go to that directory specified by java.home and you'll find the bin folder where java utilities reside. One of them is keytool.exe that is used for generating certificates. In your command line go to that directory.

Answer 2

Eclipse is using JRE/JDK specified in it's configuration (if not provided in eclipse.ini). Open preferences window (menu Window -> Preferences). Then go to Java -> Installed JREs and in the right panel you'll see all JREs. In Location column you'll see path which points to the JAVA_HOME directory.

@Deepend, you need to CD to the "java.home" Directory prior to using the Keytool (and type the command appropriately for the Shell). That is what those Instructions are asking you to do.

If you have Java 7 on WinXP open a CMD Window then type this (otherwise, adjust for your OS):

cd "C:\Program Files\Java\jre7"

bin\keytool.exe -import -file pydev_certificate.cer -keystore lib/security/cacerts

Hint: PW may be "changeit" if you never changed it and it goes without saying that you likely need to add a Path prior to the word "pydev_certificate.cer".
