Como fazer busca string no cliente/servidor?

Cara,

tu quer procurar uma String onde??? no computador dos seus clientes??? ou no teu servidor??? a aplicação agente viu que é cliente/servidor, mas a busca ficou confusa…

tenta dar uma reestruturada na tua pergunta, q a moçada vai te ajudar com certeza…

Bom é o seguinte eu fiz um codigo de um cliente/servidor aqui e tá funcionando blz os usuarios podem se comunicar atraves de mensagens, agora eu queria que o usuario1 pudesse fazer busca atraves do servidor[tipo o emule, kazaa, só que mais simples] ele iria digitar o nome de um arquivo e iria mandar para o servidor, o servidor iria fazer a busca perguntando para cada usuario se ele teria este arquivo, e devolveria todos os resultados [todos arquivos de msm nome que o usuario1 digitou], e depois de todos os arquivos listado na tela do usuario1 ele poderia escolher qual ele acharia melhor e baixar!!
Deu pra entender agora…é que eu não sou muito bom em expressar as coisas qualquer coisa posso tenta explicar melhor.
“fritzjava” se puderes me mandar msm bah vai se uma mão na roda"
Valew!

Bom Dia!!!

Bom guri não gosto de ficar so na conversa; o trecho acima que lhe envie pega o arquivo do servidor, ele realmente funciona, já está sendo usado!!

Ele é original da Romenia cidade de Brasov sendo que seu autor principal é:
Mihai Munteanu
em 1999 aonde o java era baby ainda.

Este trecho é registrado e publicado por favor não tente vender!!

Mas é aberto

Se quiser posso lhe enviar ele por e-mail é so disponibilizar ele!!
