It might be the url, as you suggest. Try forward slashes, /, instead of
double backslashes, \\.

However, you're also likely to run into security problems. InstantDB needs
to perform a lot of disk access and Applets generally don't allow this. The
security mechanisms for Netscape and IE were completely different (and
incompatible) last time I looked. Unless things have improved lately, you
may be in for a long haul through Netscape and IE websites to find the
necessary information and tools.

Have a look at
http://instantdb.enhydra.org/software/documentation/sample-applications.html
#jdbcappl for a quick and dirty fix for Netscape.

Subject: InstantDB: open connection from applet on local machine


>Hi, all:
>
>I have an applet which is on local machine. This Applet will open a
>connection to local database. The code is as following:
>...
>try{
>  Class.forName("org.enhydra.instantdb.jdbc.idbDriver");}
>  catch(ClassNotFoundException cnfe) { cnfe.printStackTrace();}
>try{
>  System.out.println(getCodeBase());
>
>con=DriverManager.getConnection("jdbc:idb:c:\\winnt\\profiles\\jzhang\\desk
top\\test\\test.prp");
>
> }
>  catch
>  (SQLException sqle) { sqle.printStackTrace();}
>...................
>
>It works fine when I run this applet using appletviewer. But when I use
>Netscape and IE to test it, it shows that it can find the idbDriver, but
>the sentence
>con=DriverManager.getConnection("jdbc:idb:c:\\winnt\\profiles\\jzhang\\desk
top\\test\\test.prp");
>
>failed.
>Is it because that the URL representation of local test.prp file is not
>correct?  How should I write that url?
>
>Thank you!
