TCP Sockets

[PowerSystem]

Hi,

I try to create a function in Scriptmaster where I can connect to a TCP Service by using Sockets and get an result back.

The script in Scriptmaster looks like

s = new Socket(host, port);



s.withStreams { 

	input, output -> 

	output << "pingn" 

	result = input.newReader().readLine()

	}



s.close()

I always get an error like. 



[color:red]groovy.lang.GroovyRuntimeException: Could not find matching constructor for: java.net.Socket(java.lang.String, java.lang.String)



what is wrong? why did Scriptmaster not find the java classes or is there an other error?



the same groovy file running local on the machine has no problem



the client side is like

host = "localhost"

port = 8000



s = new Socket(host, port);



s.withStreams { input, output -> output << "pingn" buffer = input.newReader().readLine()  println "response = $buffer"}

the server side is like

import java.net.ServerSocket



def server = new ServerSocket(8000)

 

while(true) {

    server.accept { socket ->

        println "processing new connection..."

        socket.withStreams { input, output ->

            def reader = input.newReader()

            def buffer = reader.readLine()

            println "server received: $buffer"

            now = new Date()

            output << "echo-response($now) " + buffer + "n"

        }

        println "processing/thread complete."

    }

}

Thanks Markus

The problem is that ScriptMaster treats all input values from FileMaker as text / Strings. There is no Socket constructor that takes two strings, it expects a string and an integer.

The solution is simply to use Integer.valueOf( port ) to convert it to an Integer value. You'll see examples of this in several other ScriptMaster modules that expect numeric inputs.

Thank you very much for the advice, now it works fine

for all the code now looks like

s = new Socket(host, Integer.valueOf( port ));



s.withStreams { 

	input, output -> 

	output << "pingn" 

	result = input.newReader().readLine()

	}



s.close()
