java.net.ConnectException: Connection refused: connect on spidering

[vamsi krishna]

Hi All, 

I am invoking zap server through processBuilder from my java code.  

Process pro = new ProcessBuilder(resDir+"ZedAttackProxy//zap.bat", "-daemon", "-host", "127.0.0.1", "-port " + ZAP_PORT).start();

I am invoking the client API

ClientApi api = new ClientApi("127.0.0.1", ZAP_PORT);

When i am attempting to call spider scan, i get a connection refused exception and i doubt if the process started through processBuilder has started ZAP . 

this is the line that is causing  the exception. 

ApiResponse resp = api.spider.scan(ZAP_API_KEY, TARGET, null, null, null, null);

and below is the complete exception stack trace.

Hi.

Some questions:
- Is the path to zap.bat correct? Should have just a "/" ?
- Did you check the exit value of the process?
- Is the code waiting for ZAP to fully start? (The API client has a
method to wait for ZAP's proxy to be ready to receive API calls
("waitForSuccessfulConnectionToZap")).

Best regards.

Thankyou for those inputs. 

Path to zap is correct and processBuilder doesnt show any errors while creating process.   I was not waiting for the zap to start fully.  Hence added "waitForSuccessfulConnectionToZap" code.  Process exit code is 1.  Does this mean it exited with some error.  

I get a timeout after waiting for specified seconds for zap to wait. 

Exception : Unable to connect to ZAP's proxy after 150000 milliseconds.

java.lang.RuntimeException: Unable to connect to ZAP's proxy after 150000 milliseconds.

Regards,

Vamsi.
