(RESOLVIDO) Erro ao executar um projeto no Netbeans (please, help me!)

Olá a todos. Eu estou tentando executar um projeto que criei no Netbens, mas o mesmo não executa (no caso quando clico no botão cuja ActionPerform ja esta configurada), gera o seguinte erro:

Estou rodando o Netbeans no Ubuntu. Será que alguém poderia me ajudar por favor?

No metodo private void btnClicActionPerformed, ao inves de lblResul = setText(Double.toString(soma));
coloque lblResul.setText(soma); ou lblResul.setText(Double.toString(soma));

XikuGuarana · Maio 10, 2016, 1:16pm

Vlw pela ajuda, eu substitui o comando lblResul = setText(Double.toString(soma)); para lblResul.setText(Double.toString(soma)); e funcionou. Vlw mesmo cara.
