Hi,

we are developing a legal p2p-filesharing system in JXTA combined with web services and additionally we want to use a persistence layer. Our web services are running on a tomcat server. Before our p2p clients can exchange any data they must verify on a Trusted Third Party(TTP) our web services if the content they want to exchange is legal. Our web service have to access a centralized database where we have for example two tables. One Table(White
List) holds the contents which are registered as sharable and a another table(Black List) contains the contents which are registered as not sharable. In these two tables the primary key is a blob field.

My question is it possible to query in these fields. What I mean is that my clients sends a byte[] and what the service had to do is to query these two tables to see if it match to the primary key fields in theses two tables.



Regards

Ferruh
