Re: user can't access own database after creation - Mailing list pgsql-jdbc

Well, I don't use JDBC methods directly - just like the OP, I do use JPA for database access, and set "Target Database" to PostgreSQL - IN THIS SPECIFIC CASE - is enough so it will not throw any errors.

I would still put by coins in generating a verbose log. OP shall be facing other issue, not a JDBC issue at all.

I've more than 7 years working with PgSQL, JPA and JDBC, and found only one "prepared statment" glitch with JDBC+timezone+DST, which can be easly solved with "prepareThreshold=0" in connection string - I don't even think it is a JDBC issue, but a server side prepared statements issue.
All other issues I've faced so far were caused by my own mistakes on setting configuration parameters.

However if the appserver attempts to use a jdk 1.8 JDBC method it will fail miserably. As long as you stay to jdk 1.6 methods you will be fine with those JVM's

This is the same I use in production servers either with JDK 1.7_80 and 1.8_65.
Also, postgresql-9.3-1101.jdbc41.jar works well with both Java versions.

You can add additional logging JPA and JDBC specific:

JPA:
With EclipseLink, I do use the following property:

      <property name="eclipselink.logging.level" value="DEBUG"/>

You can set it at runtime, but you should look at it - and also check if your provider has similar option.
In my application, I've left all defaults in configuration file (persistence.xml), and just adjust the custom properties at runtime.

JDBC:
You can add higher logging for jdbc itself with

jdbc:postgresql:// 10.10.10.100:5432/benexus?loglevel=2

Double check configuration:
Just in case, to make connections out of 127.0.0.1 you must configure postgres with "listen_address = '10.10.10.100' or listen_address='*' and port = '5432' in postgresql.conf; also in pg_hba.conf you must have the line "host all all 10.10.10.99/32 md5".

The programmer says that she relies on JPA to establish the connection, but I suppose that JDBC is still involved, otherwise i can’t see how java would talk to postgresql. 

Unless JPA does so directly.

Like I said, Java really isn’t my thing.

Thanks a lot, everyone (and specially Dave Cramer).

Now I know the issue is not JDBC related.

Not sure of this is good news for me, though :)

I’d think that the application needs to be amended.

Still, this does not account for the fact that it works on a local win machine.

As you can see, Dave’s little program connects like a charm,
