How to dynamically add New Proxy service in Membrane Proxy

[abhinav rastogi]

HI all ,

I am trying to create a wrapper over membrane proxy. 

What i wish to do , 

1. Add Service Proxies / proxies dynamically in a running instance of Membrane 

2. I do not want to use Proxies.xml to add new service proxies dynamically but use code to initialize the objects.  

2. Do not want to restart the membrane everytime new service proxy is added , similar to hot deployment

KIndly guide me as i am new to this .

Regards

Abhinav

Hi Abhinav,
you can use the Membrane Java API and embed Membrane into your program:

Thanks for the input , i tried using add and remove in the router object and Rule Manager object but when i am updating a Rule by replacing the current object with a new rule object. It is reflecting in the admin console but not redirecting ?? CAn some one please guide me as to what i am missing ??

Hi Abhinav,
to help you I need more details. What do you mean here by not redirecting? Can you post your setup, how it behaves and how it should behave?

Cheers,
Thomas

public static void updateSP()  {

String hostname = "*";

String method = "*";

String pathold = "^/sachin.*";

String pathnew = "^/abhinav.*";

int listenPort = 80;

Iterator<Rule> ruleIterator = router.getRuleManager().getRules().iterator();

while (ruleIterator.hasNext()) {

Rule rule = ruleIterator.next();

Rule ruleNew;

try {

ruleNew = rule.clone();

ruleNew.getKey().setPath(pathnew);

System.out.println("Before " + rule.getKey().getPath());

if (rule.getKey().getPath().equals(pathold)) {

router.getRuleManager().replaceRule(rule, ruleNew);

}

} catch (CloneNotSupportedException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (Exception e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

}

Hi Abhinav,
the code below should not remove the admin service proxy. Do you do a router.init(), restart or something similiar?

Can you printout the rules and their configuration, then change the rule and again printout the configuration?

Cheers,
Thomas

} catch (CloneNotSupportedException e) {

}

}

}

but it is also removing admin Service Proxy.

Hi Abhinav,

have a look at EtcdBasedConfigurator.java . It also dynamically adds and removes serviceProxies.

Best,
Tobias
