View source for 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;

== Colocando os arquivos em produção ==

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 

Edite o arquivo ibmproxy.conf
