JBuilder QueryDataSet: Can't browse tables in Query Editor

Playing with the JBuilder GUI, I am trying to set up an instance of the
QueryDataSet component using the Query Editor.
The targetted table resides within a remote PostgreSql database which
JBuilder is connected to through the Postgres JDBC driver.
Connecting the JBuilder IDE to the database using the Connection Editor
was successful.

Within the Query Editor, I performed the following steps:
- bind the query to the relevant Database component: OK
- push down the button 'Browse tables': this causes the message:
       ERROR:  parser: parse error at or near ""
  to be displayed.
  This message is apparently reported by the JDBC driver. The PostgreSql
  server log file logs the same error message.
- Then, manually entering a query, say: "select * from bar", and pushing
  down the button 'Test query' is successfully acknowledged, though the
  server reacts by logging the message:
       ERROR:  t: Table does not exist.

Any idea ?
Thanks in advance (again) for any help.
