Hi,

*- String question:*

I'm newbie and i'm little surprise aboud String (java) and hashcode .....
If I understand right, on each create string, created a hashcode ?  (true 
?)( but I need this only for equal-method ?) 
mostly I don't need hashcode ! 
In web using very often String, for Images and Text and and ....why don't 
use char[] or byte[] ? 
If I transfer 100kb String Image .... I think this create hashcode, take a 
much performance ? (or not ?)

What is on the client side, (I don't known javascript ) GWT  translated to 
similar objects with hashcode ?

what is the best way ? ( today )

for keywords or links I'm very happy ! 


*- View Raw Image question:*

I have my Images (jpg) in database in raw format and transfer this over 
websocket (binary) ....now How I can performant show It ?
I see already solution with convert to Base64 ...and decompress it (jpg) 
 but this is not direct way ? ( take much unnecessary performance....)

what is the best way ? ( today with html5)

for keywords or links I'm very happy !
