I don't know whether you are still in a position to give more details on this issue, but I have tried to construct a test case based on what you've reported. Here's what I came up with. The trouble is, in my environment it works as expected and doesn't crash. I wonder if you could try it in an empty db in yours.
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Timestamp;
import java.util.logging.Logger;
import org.postgresql.pljava.annotation.SQLAction;
import org.postgresql.pljava.annotation.SQLActions;
import org.postgresql.pljava.annotation.Function;
@SQLActions({
@SQLAction(provides="invoice_batch table", install=
"CREATE TABLE invoice_batch AS " +
"SELECT now() AS time_created, 42 AS id", remove=
"DROP TABLE invoice_batch"
),
@SQLAction(requires={"invoice_batch table","whenCreated fn"}, install=
"SELECT whenCreated(42)"
)
})
public class ttest
{
@Function(provides="whenCreated fn")
public static void whenCreated(Integer batch)
throws SQLException
{
Timestamp createTimeStamp = null;
java.sql.Connection sqlConnection =
DriverManager.getConnection("jdbc:default:connection");
String sql = "SELECT time_created FROM invoice_batch where id = "
+ batch.toString();
ResultSet result = sqlConnection.createStatement().executeQuery(sql);
if (result.next()) {
createTimeStamp = result.getTimestamp("time_created");
}
Logger.getAnonymousLogger().warning(String.valueOf(createTimeStamp));
}
}If you build a jar from the above, say ttest.jar, you can run the test simply with SELECT sqlj.install_jar('file:///path/to/ttest.jar', 'ttest', true); and if things are working it should produce a WARNING with the timestamp value. In your case, I guess it should crash. Or if it doesn't crash, perhaps you could look for how it is different from your first example and what needs to be changed until it does crash?
Thanks, -Chap

I have successfully built Pljava using maven on windows against PostgreSQL 9.3 (32 bit), using the latest pull request #29 (Fix to allow building pljava with Microsoft C). Thank you for that ! Everything is working except for.....
(6 lines of code) java.sql.Connection sqlConnection = DriverManager.getConnection("jdbc:default:connection"); sql = "SELECT time_created FROM invoice_batch where id = " + batch.toString(); java.sql.ResultSet result = sqlConnection.createStatement().executeQuery(sql); if (result.next()) { createTimeStamp = result.getTimestamp("time_created"); }
.....where the result.getTimestamp crashes the JVM.
The log file generated by postgreSQL is included below. I think it has all java info needed!
