Cannot run program "keytool": java.io.IOException

Question

Hi,
I would like to follow the procedure to change the master password
of glassfish server hosting APEX listener
using the change-master-password subcommand, but the utility keytool
is not found:
glassfish@ahost:/opt/glassfish3/glassfish/domains/mydom01/config> /opt/glassfish3/bin/asadmin
/opt/glassfish3/bin/asadmin
Use "exit" to exit and "help" for online help.
asadmin> change-master-password mydom01
Enter the current master password> changeit
Enter the new master password> changedit
Enter the new master password again> changedit
Cannot run program "keytool": java.io.IOException: error=2, No such file or directory
Command change-master-password failed.
asadmin>
Command multimode failed.
glassfish@ahost:/opt/glassfish3/glassfish/domains/mydom01/config> which java
/usr/bin/java
glassfish@ahost:/opt/glassfish3/glassfish/domains/mydom01/config>
All of glassfish is running fine apart from this.
keytool could be found in /usr/java/latest/bin/keytool.
Do we need to have this in the path? There is no requirement in the
install guide for this, nor did the RPM installation adjust the system
path accordingly.
Hopefully someone can tell my how things ought to be regarding keytool?
Thanks, Tom

Hi Tom,
the procedure to change the master password of glassfish server hosting APEX listener... sounds more like a GlassFish-related topic to me. I guess you'd get the best answers for such questions in a GlassFish-related forum...
For what it's worth, I'll try my best anyway:
Cannot run program "keytool": java.io.IOException: error=2, No such file or directoryThis seems to be a pretty clear error message: keytool , which is probably used to manage the keys for GlassFish users, wasn't found. This means, you're either running on an OS that is not officially certified for GlassFish, or you GlassFish hasn't been configured properly.
You ran
glassfish@ahost:/opt/glassfish3/glassfish/domains/mydom01/config> which java
/usr/bin/java... which indicates you assume your GlassFish is running without JAVA_HOME being set. If that's true, I'd begin to setup you GlassFish properly starting with that parameter.
Anyway, you also found out that
keytool could be found in /usr/java/latest/bin/keytool.... which is not +/usr/bin+ and hence probably not in the global search path of the user on whose behalf your GlassFish is running. So, you could either create a link-set[*] for +/usr/bin/keytool+ to (finally) point to +/usr/java/latest/bin/keytool+, or you setup JAVA_HOME to be +/usr/java/latest+ .
[*] Note that depending on your OS there might be more than one stage of indirection, e.g. my Ubuntu has +/usr/bin/java+ pointing to +/etc/alternatives/java+ which is pointing to +/usr/lib/jvm/java-6-sun/jre/bin/java+ where +/usr/lib/jvm/java-6-sun/+ is pointing to the directory containing the actual JDK to be used. You'll probably find something like that on your system as well. My Ubuntu box has a link for +/usr/bin/keytool+, so I get that when running "which keytool".
Do we need to have this in the path? There is no requirement in the install guide for this, nor did the RPM installation adjust the system path accordingly.Again, this is not a GlassFish forum.
I hope my hints help you solve your problem. If they don't, please choose the appropriate forum for your next post on that topic. And I guess, giving some more information on your OS and how you manage your JDK (and which version you use) will help people there to help you.
Thanks,
Udo
