Failed to get database schemas of a JAR database
------------------------------------------------

                 Key: DERBY-3546
                 URL: https://issues.apache.org/jira/browse/DERBY-3546
             Project: Derby
          Issue Type: Bug
          Components: JDBC
    Affects Versions: 10.3.2.1
         Environment: Sun JRE 1.5.0_08
Windows Server 2003
            Reporter: Gary Xue


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:

Exception in thread "main" java.sql.SQLException: Container was opened in read-only mode.
