IBM Edge Server: Criando Paginas de Erro Customizadas
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;

Vá para o diretório de configuração do edge
# cd /opt/ibm/edge/cp/server_root/pub/en_US
Faça um backup do arquivos originais
# mv errorpages errorpages_orig
Crie o novo diretório
# mkdir erropages # cd errorpages
Coloque os arquivos criados no novo diretório
Ajustando a configuração no ibmproxy.conf
Vá para o diretório de configuração do edge
# cd /opt/ibm/edge/cp/etc/en_US
