javascript - how to receive ArrayList object in nodejs from java program

问题描述:

I have written a program, where I have to send an ArrayList to Java code through my NodeJS program.

The java program sends back an ArrayList to Nodejs as a response.

I am able to send the ArrayList to Java, and do manipulations.

Sending back the ArrayList from java is also working fine since I have used the System.out.print to verify that.

The problem is in receiving the ArrayList in Nodejs.

Below is the sample code I had written. The NodeJS is printing only "Item_2" twice in the output, whereas it should have printed "Item_1" and then "Item_2".

var confList = java.newInstanceSync("java.util.ArrayList");

confList.addSync("Item_1");

confList.addSync("Item_2");

var dataList = java.newInstanceSync("java.util.ArrayList");

var javaApp = java.newInstanceSync("TestJava");

javaApp.getData(confList, function(err, ret)

{

if(err) {

console.log("getData method in Java failed" + err);

}

else {

dataList = ret;

var data = dataList.getSync(0);

console.log(data.toStringSync());

var data = dataList.getSync(1);

console.log(data.toStringSync());

}

});

Java code:

public class TestJava

{

public ArrayList<String> getData(ArrayList<String> conf) throws Exception

{

ArrayList<String> list = new ArrayList<String>();

for(String val: conf)

{

val = //some modifications in conf;

list.add(val);

}

return list;

}

}
