pqno, esse erro (java.lang.OutOfMemoryError ) ja aconteceu comigo, quando eu tentava carregar uma tabela muito grande do oracle. O default da VM eh 64M, então tive que executar o programa da seguinte forma:

java -Xmx256m -cp class Banco

-XmxZZm onde ZZ é o tamanho da sua RAM

comigo funcionou, mas só quando executo pelo DOS…
falow!
