IBM Edge Server: Criando Paginas de Erro Customizadas

From Wiki

Podemos customizar o IBM Edge Server para gerar arquivos com o estilo da empresa. Para isso realize os procedimentos abaixo:

Procedimento:

Criando o modelo

1) Crie um diretório c:\errorpages e adicione os css e imagens.

2) Crie um arquivo de modelo html de modelo para validar.

3) Após fechado o modelo, altera a função printFile, no script aplicativo java, para gerar os arquivos htmls.


Criando os arquivos com um java

Gere os arquivos utilizando o seguinte aplicativo java

import java.io.FileOutputStream;
import java.io.PrintStream;

	public static void main(String[] args) {
		MontaEdgeCustomMessages run = new MontaEdgeCustomMessages();
		System.out.println("MontaEdgeCustomMessages - Start");
		run.runMain();
		System.out.println("MontaEdgeCustomMessages - End");
	}
