I have been stuck with this issue longer than i want to admit. I am trying to use postgres db connection for my small spring mvc project over liberty. My server.xml looks like below.
<server description="new server">

I have tried connecting to postgres by all methods eg: datasource and also connection manager
Properties info = new Properties();
String url = "jdbc:postgresql://ea957de9-2271-4d6c-999e-f2c250575850.budepemd0im5pmu4u60g.databases.appdomain.cloud:30352/clouddb";
info.setProperty("user", "");
info.setProperty("password", "");
info.setProperty("ssl", "true");
info.setProperty("sslfactory", "org.postgresql.ssl.SingleCertValidatingFactory");
info.setProperty("sslfactoryarg", loadFile("/opt/ibm/wlp/usr/servers/defaultServer/resources/security/PGSSLROOTCERT.crt"));
Even after providing the root.crt from the postgres db connection page I keep getting
[err] org.postgresql.util.PSQLException: SSL error: Received fatal alert: handshake_failure [err] at org.postgresql.ssl.MakeSSL.convert(MakeSSL.java:42) [err] at org.postgresql.core.v3.ConnectionFactoryImpl.enableSSL(ConnectionFactoryImpl.java:435) [err] at org.postgresql.core.v3.ConnectionFactoryImpl.tryConnect(ConnectionFactoryImpl.java:94) [err] at org.postgresql.core.v3.ConnectionFactoryImpl.openConnectionImpl(ConnectionFactoryImpl.java:192) [err] at org.postgresql.core.ConnectionFactory.openConnection(ConnectionFactory.java:49) [err] at org.postgresql.jdbc.PgConnection.(PgConnection.java:195)
I also have tried to pass the certificate in my keystore and truststore.. Nothing seems to work in this case.. I can connect successfully to the postgres db locally via IDE and also through psql but as soon as i dockerize it and run, it throws this exception.
