Description

When a database residing in a JAR file is open via Derby embedded JDBC connection, the getSchemas() call on the connection's DatabaseMetaData fails with an exception: ERROR 40XD1: Container was opened in read-only mode.

STEPS TO REPRODUCE:
(1) Download the attached JAR database, BirtSample.jar, and place it in C:\ (or if another location, update the dbFile variable in test code below).
(2) Run the following Java test code, with derby.jar (version 10.3.1.1) in classpath.

// *** BEGIN TEST CODE
import java.sql.Connection;
import java.sql.DatabaseMetaData;
import java.sql.DriverManager;
import java.sql.ResultSet;

public class TestGetDBMetaData
{
public static void main(String[] args) throws Exception

{ final String dbFile = "c:/BirtSample.jar"; final String driverClass = "org.apache.derby.jdbc.EmbeddedDriver"; final String url= "jdbc:derby:jar:(" + dbFile + ")BirtSample"; final String user = "ClassicModels"; final String pwd = ""; Class.forName( driverClass ); Connection conn = DriverManager.getConnection( url, user, pwd); DatabaseMetaData dbmd = conn.getMetaData(); ResultSet rs = dbmd.getSchemas(); rs.close(); conn.close(); }

}

// ***END TEST CODE

The following exception happens in the getSchemas() call:
