Erro: access denied (java.io.FilePermission c:\arquivo.txt write)

Arrrrrrghhhhh! Tem dias que tudo parece dar errado! a horas procuro solução para um problema!

Seguinte….

Estrou trabalhando numa aplicação JAVA + ORACLE +Tomcat5.5.23

E estava obetendo os seguintes erros:

java.security.AccessControlException: access denied (java.io.FilePermission C:\arquivo.txt write)
at java.security.AccessControlContext.checkPermission(Unknown Source)

outro erro:

Então! eu nunca estava tendo esse problema, pois antes eu trabalhava com a versão 5.0 do Tomcat (se não me engano)!

Descobri que nessa nova versão é preciso configurar no arquivo de configuração “apache-tomcat-5.5.23\conf\catalina.policy”

Adicionando com a seguinte configuração:

——————————————

//permissão de acesso a url “127.0.0.1:1521″, utilizado pelo oracle
grant codeBase “jar:file:G:/xxxxx/WEB-INF/lib/ojdbc14_g.jar!/-” {
permission java.net.SocketPermission “127.0.0.1:1521″, “connect”;
};

//permissão para ler e gravar (todos os arquivos), utilizado pelo oracle
grant {
…
permission java.io.FilePermission “<<ALL FILES>>”, “read”;
permission java.io.FilePermission “<<ALL FILES>>”, “write”;

permission java.util.PropertyPermission “oracle.*”, “read”;
}

ufá!
