Great. Then it is exactly what I thought: a bug I already solved. You can interchange the jdbcclient.jar with your monetdb-jdbc-1.X.jar file. The former contains the latter, and in your case, the latter is outdated. > > I noticed that your system does not have openssl and/or > > libpcre > > available.

The driver you use in your application is too old. You need to use a more recent driver, such as the one included in jdbcclient.jar.

Correct, no redirection is performed in that case. > What do you suggest I try next either to resolve it or to collect more > troubleshooting information? Use the jdbcclient.jar as your JDBC driver, throw away the old one. ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
