I need to have the same application deployed in GlassFish several times, with different JNDI parameters, but I can't find a way to do that.
I know I can have different standalone instances and apply the different JNDI resources to one or several instances, but I can't have the same resource name with different values for the different instances. What is the way to achieve what I need?
要实现此要求,可以在属性文件中使用不同的JNDI配置,并传递JVM参数中的值,以将每个配置应用于多个glassfish服务器实例。
So in the end what I did is to use this:
@Resource(lookup = "java:app/AppName")
private String appName;
private String myJndiParameter;
And then since I can't use a variable to get the custom jndi parameter in an annotation, I created a @PostConstruct method, where I get the jndi value that I want, something like this:
@PostConstruct
public void initialize ()
{
try
{
myJndiParameter = (String) new javax.naming.InitialContext().lookup(appName + "/" + "my.jndi.parameter.name");
} catch (NamingException e)
{
// Treat exception
}
}
In GlassFish, my custom resource name looks like:
myapp/my.jndi.parameter.name
I'm open to suggestions to improve it :)
