Question: How to start web console with non-core lib

[saikrishna321]

@albertlatacz i have used java-repl for building my project for testing purpose, and wanted to embed it into web by starting the jar which i have build

for ex: java -jar appiumrepl.jar from command line

If i embed the iframe for webconsole which is provided that gets the java-repl.jar by default, instead i want the webconsole to start with the jar which i build..

any help on this ?

This has improved from version 415.

You can now add multiple expressions (one per line) into javarepl.init file in current directory, for example:

./javarepl.init

:cp http://repo1.maven.org/maven2/joda-time/joda-time/2.9.6/joda-time-2.9.6.jar
:cp http://repo1.maven.org/maven2/com/javarepl/javarepl/415/javarepl-415.jar

then you can also add --expression flag when starting JavaREPL to pass single expression:

$ java -jar build/libs/javarepl-dev.jar --expression="name = \"Java REPL\""

should output

@albertlatacz instead of starting the webconsole with java-repl-415.jar and then add the :cp joda-time.jar, can't we start the webconsole by adding it directly to the jar file ?

[albertlatacz]

Sure, it's more in a case where you don't want to embed it. Not sure if I understand what you're trying to do. Do you want to reuse web console and expose it in your app?

[saikrishna321]

@albertlatacz yah your right .. i want to reuse web console and expose to ma app..

[albertlatacz]

Unfortunately it's not exposed at the moment. There is a way to connect to embedded repl. What you could do is to configure it like in javarepl.examples.EmbedInApplication and then connect command line repl with

java -jar build/libs/javarepl-dev.jar --hostname=localhost --port=8001

Hope that helps.

@albertlatacz i get the below error

I think I understand now.

Appium bundles all libraries required, right?

So you could package them all in fat jar

build.gradle

plugins {
    id "com.github.johnrengelman.shadow" version "1.2.4"
}

apply plugin: 'java'

repositories {
    mavenCentral()
    maven { url "https://plugins.gradle.org/m2" }
}

jar {
    manifest {
        attributes 'Main-Class': 'com.javarepl.App'
    }
}

dependencies {
    compile 'com.javarepl:javarepl:417'
    compile 'joda-time:joda-time:2.9.6'
}

Then start JavaREPL like so

package com.javarepl;
import javarepl.Main;

public class App {
    public static void main(String[] args) throws Exception {
        Main.main(args);
    }
}

then after building with

$ gradle clean shadowJar

you should have javarepl-app-all.jar

then run

$ java -jar build/libs/javarepl-app-all.jar

Example project below

javarepl-app.zip

@albertlatacz this just builds the fat jar with java-repl as base. i was able to do this with ma project.All that i wanted to do is, acess the fat jar through webconsole ..

Working example:: https://github.com/saikrishna321/AppiumReplJava

mvn clean install

java -jar target/appiumrepljava-1.0-SNAPSHOT.jar

this gets the java repl, i want to access the same from webconsole

[albertlatacz]

Ahhh, yes, this would be a useful feature.

I have added a way to access local repl through web interface. Once you build as above with latest version and run you should get

and then should also be able to access the web interface

which you can then embed wherever.

[saikrishna321]

@albertlatacz awesome that was quick, works well. Is there a way we can set port and hostname?

this didnt work
java -jar /Users/saikrisv/git/AppiumJavaRepl/target/appiumrepljava-1.0-SNAPSHOT.jar --port=4723

Welcome to JavaREPL version null (Java HotSpot(TM) 64-Bit Server VM, Java 1.8.0_111)
ERROR: Could not connect to remote REPL instance at http://localhost:4723

[albertlatacz]

Ok, try version 424 including port as you were.
