Pessoal, bom dia!!
Está dando esta exception quando eu faço uma chamada ao meu arquivo jasper.

ReportJasper jasper = new ReportJasper(map, fileInputStream, list, path);
jasper.doReportPdfStream(response.getOutputStream());

Alguém sabe o que pode ser?

grato.

quantos registros esta retornando?

A memoria da sua JVM é insuficiente. Aumente a memoria passando os parametros -Xms256M -Xmx1024M na linha de comando.

-Xms256M = JVM começa alocando 256Mb
-Xmx1024M = JVM chega até 1gb.

abraços.

já passei no eclipse…

run configuration > arguments > vm arguments
-Dcatalina.base=“C:\workbench\tomcat”
-Dcatalina.home=“C:\workbench\tomcat”
-Dwtp.deploy=“C:\workbench\tomcat\wtpwebapps”
-Djava.endorsed.dirs=“C:\workbench\tomcat\common\endorsed”
-DXmx=512m
-DXms=512m

Trás somente 4 registros na minha lista, mas acho que esta dando looping infinito no jasper.

Era o jasper que não tinha compilado perfeitamente…

Agora com o jasper já compilado e com a tipagem dos objetos correta, não mostra nada no relatório, mostra o pdf em branco e não gera nenhuma exceção.
grato
