Hello,
I am trying to setup a SSL-enabled Tomcat 5.5.? (5.5.20 I think) on
a Sun Solaris 10 (Sparc) but it turns out that this appears not to
be an easy task.
Hopefully you guys can shed some light on this. Basically I do have
a Verisign-signed SSL certificate which I would like to add to my
existing Tomcat config. Now after spending hours of tweaking the
config, I do face two problems: Either Tomcat is unable to find
my alias in the keystore file or there appears to be a problem with
the SSL ciphers or certificate itself. Hopefully somebody knows what
to do, this
is giving me a headache for many hours now.
Here is what I did (steps taken from
http://tomcat.apache.org/tomcat-5.5-doc/ssl-howto.html, "Importing
the Certificate"), please
note that I removed IPs, hostnames etc. to protect the innocent:
1) Import of the Verisign root cert into my keystore:
$ keytool -import -alias root -keystore wstest -trustcacerts -file
verisign.crt
Enter keystore password: XXX
Owner: OU=www.verisign.com/CPS Incorp.by Ref. LIABILITY LTD.(c)97
VeriSign, OU=VeriSign International Server CA - Class 3,
OU="VeriSign, Inc.", O=VeriSign Trust Network
[ ... ]
Certificate was added to keystore
2) Import of my Verisign-signed SSL certificate:
$ keytool -import -alias tomcat -keystore wstest -trustcacerts -file
mysystem.crt
Enter keystore password: XXX
[ ... ]
Certificate was added to keystore
3) Change of my Tomcat configuration in server.xml to use the new
keystore and SSL cert:
<Connector port="8443" maxHttpHeaderSize="16384"
address="myhostname" enableLookups="false"
disableUploadTimeout="true" acceptCount="100"
maxKeepAliveRequests="100"
scheme="https" secure="true" clientAuth="false"
compression="8192"
compressableMimeType="text/javascript,text/css"
keystoreFile="/usr/local/tomcat/conf/wstest"
keystorePass="XXX" sslProtocol="TLS" keyAlias="tomcat"
/>
4) Restart of Tomcat and review of Tomcat log file:
# svcadm disable tomcat
# rm ../logs/catalina.out
# svcadm enable tomcat
# tail -f ../logs/catalina.out
[...]

However my keystore DOES contain my two keys (Verisign's key as well
as my SSL cert):
# keytool -list --keystore wstest -v
Enter keystore password: XXX
Keystore type: jks
Keystore provider: SUN
Your keystore contains 2 entries
Alias name: root
Creation date: Aug 29, 2007
Entry type: trustedCertEntry
Owner: OU=www.verisign.com/CPS Incorp.by Ref. LIABILITY LTD.(c)97
VeriSign, OU=VeriSign International Server CA - Class 3,
OU="VeriSign, Inc.", O=VeriSign Trust Network
[...]
*******************************************
*******************************************
Alias name: tomcat
Creation date: Aug 29, 2007
Entry type: trustedCertEntry
Owner: CN=myhostname, ...
[...]
*******************************************
*******************************************
Here is the first problem: Why does my alias "tomcat" not identify a
key entry in the keystore? It does exist, doesn't it?
5) Now to get around this problem, I removed the "keyAlias"
directive from the Tomcat config which now like like this:
<Connector port="8443" maxHttpHeaderSize="16384"
address="myhostname" enableLookups="false"
disableUploadTimeout="true" acceptCount="100"
maxKeepAliveRequests="100"
scheme="https" secure="true" clientAuth="false"
compression="8192"
compressableMimeType="text/javascript,text/css"
keystoreFile="/usr/local/tomcat/conf/wstest"
keystorePass="XXX" sslProtocol="TLS"
/>
6) Then I restarted Tomcat and here is what I get in the logs:
# svcadm disable tomcat
# rm ../logs/catalina.out
# svcadm enable tomcat
# tail -f ../logs/catalina.out
[...]
java.net.SocketException: SSL handshake

Another problem. Any ideas?
7) Then I tried to change the sslProtocol to SSL (rather than TLS)
but that didn't change anything. The file permissions of the certs
are okay,
they are all world-readable.
So guys any ideas on how to solve this? Has anyone ever encountered
this problem? I searched on Google but I really was unable to
find a proper solution.
Any input is greatly appreciated. Thank you very much.
Best regards,
Werner.
