Try to catch if an instance is running

[Paul-Benoit Larochelle]

Hello,

sorry do not know if I e-mail at the good place... not clear in the html
where to post a question

I'm using an embedded database...
if an instance is already running I would like to be able to send a
message to the user "you already have an instance of the application
running"
however even if I do

try {
conn = DriverManager.getConnection(url, username, password);
}
catch (Exception e) {
System.out.println(
"Unable to make a connection to the database.\n" +
"The reason: " + e.getMessage());
return;

}

the catch catches nothing and the application crashed with an error
about the journal file
How can I trap the exception ?

Thanks Paul-Benoit
