Accessing PostgreSQL through JDBC via a Java SSL tunnel

Nice job! Your article is well structured and highly informative. Any software requiring secure network communications can benefit from the relay client and server.

I tried Accessing PostgresSQL throgh Java SSL tunnel using samples of keytool and Java class, but I only got a message as below. Could you give me some advice. I am developing an applet of a database application, and I need SSL connection for it.
Starting relayapp ...
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: No trusted certificate found
Creation of the keystores are as below.
keytool -genkey -alias serverprivate -keystore kan2store -keyalg rsa -keysize 2048
keytool -export -alias serverprivate -keystore kan2store -file server.cer -rfc
keytool -import -alias trustservercert -file server.cer -keystore clienttrustkanstore
keytool -genkey -alias clientprivate -keystore kanclstore -keyalg rsa -keysize 2048
keytool -export -alias clientprivate -keystore kanclstore -file client.cer -rfc
keytool -import -alias trustclientcert -file client.cer -keystore servertrustkanstore

The problem has just been solved. I placed the clienttrustkanstore and the servertrustkanstore at the reverse site. After putting them at the correct site
I got SSL connection. I really appreciate you and your articles, thank you.

while I was trying to install JDBC driver reading your article everything went well until a change was to be made in the pg_hba.conf file where you have given a statement with 5 parametres [ host,all,127.0.0.1,255.255.255.255,password ].
At this point the error I'm receiving from the pgsql sever is
-->A connection error has occurred: org.postgresql.util.PSQLException: FATAL: no pg_hba.conf entry for host "::1", user "sridhar", database "sridhar", SSL off.
And one more doubt , should I set a JDBC classpath excluding the jar file in the jdk calsspath.
Could you please help me in this situation.
