I've just installed iSQL-Viewer and used its wizard to set up a connection to the VOC database that I loaded into MonetDB. But the connection doesn't work; instead I see an error apparently from MonetDB: java.sql.SQLException: ResultSet is closed! at nl.cwi.monetdb.jdbc.MonetResultSet.absolute(MonetResultSet.java:181) at nl.cwi.monetdb.jdbc.MonetResultSet.relative(MonetResultSet.java:2014) at nl.cwi.monetdb.jdbc.MonetResultSet.next(MonetResultSet.java:1981) at org.isqlviewer.sql.ResultSetWrapper.next(ResultSetWrapper.java:1194) at org.isqlviewer.ui.JdbcWorkbench.buildSchemaMenu(JdbcWorkbench.java:1145) at org.isqlviewer.ui.JdbcWorkbench.changeConnection(JdbcWorkbench.java:695) at org.isqlviewer.ui.JdbcWorkbench.actionPerformed(JdbcWorkbench.java:290) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:616) at org.isqlviewer.swing.action.SwingEventManager$EventLoop.delegateEvent(SwingEventManager.java:340) at org.isqlviewer.swing.action.SwingEventManager$EventLoop.run(SwingEventManager.java:319) at java.lang.Thread.run(Thread.java:636) I've googled the error message without finding anything relevant. I know the VOC database itself works because I managed to connect to it via both the command-line and using SQuirreL. The merovingian.log just says: 2010-04-13 14:06:14 MSG merovingian[7379]: proxying client pcx36.lmb.internal:52677 for database 'test' to mapi:monetdb://127.0.0.1:50002/test Can anybody give me a clue what might cause that error message? Thanks, Dave
