As DBTools is a C-based API, I guess a usage from Java will require some kind of JNI interface or the like - can't tell more, haven't done that...

Another approach with a looser coupling might be to make use of the MESSAGE statement to pass messages to other connections. ODBC apps can process such messages by using a particular callback - that works well IMHO. SA 11 JDBC clients seems to be able to read them as well, but I don't have a sample at hands.

The basic idea would be to

• have a JDBC app that waits for input
• turn the connection id of that waiting connection to a program that can call a C DLL
• use a classic DBTools C DLL that calls DBBackup() and uses the callbacks to build according MESSAGE statements for a given connection ID, such as:
  

extern short _callback MessageRtn(char * messagestr)
{
if (messagestr != NULL)
{
// build message string from messagestr, such as
// sqlstr = "MESSAGE messagestr + " TO CLIENT FOR CONNECTION " + MyConnId + " IMMEDIATE"
// use ODBC or whatever C DB APO to execute that SQL statement
}
return (0);
}

So the DBTools DLL could "send" the progress messages of the backup to the JDBC connection.

Apparently, one could also make the DBTools API DLL to write messages to a file or send them via some IPC mechanism, and make the JDBC app read them...
