With Java 1.2 came the Collections class and the beginning of "programming to the interface". 'Vector' carries functionality not required all the time, to whit, method synchronization. It also sports legacy methods not consistent with the Collections framework. Its direct replacement is 'ArrayList' for unsynchronized work, and 'Collections.synchronizedList( List someList )' for synchronized work. Java 5 added generics to all that. Nowadays you'd use: List <Result> resultRec = new ArrayList <Result> (); -- Lew

In which case SQLServer may not be that difficult, because SQLServer also uses T-SQL although today Microsoft's and Sybase's dialects has somewhat diverged. Arne

Java is not exactly Microsofts backyard, but a recent study showed that Java EE projects was deployed: Windows 57% Redhat & Centos 35% Suse 12% Other Linux 16% Solaris 18% AIX 14% HP-UX 5% Other 7% (it adds up to more than 100% because some projects targets multiple platforms) For .NET the Windows percentage is approx. 100%. That is a lot of Windows servers. http://en.wikipedia.org/wiki/Usage_share_of_operating_systems#Servers gives the same picture. Arne

It still requires Java on the client. Arne

I think that confirms Arveds claims. Arne |
