error when using the import java class

Open RenanChagas opened this issue 7 years ago • 6 comments

Hi everyone,

I have a java dependency that I need to add to my nodeJS application. I manage to run all the commands in the tutorial and my code look like this:

    var java = require("java");
    java.classpath.push("commons-lang3-3.6.jar");
    java.classpath.push("commons-io-2.4.jar");

    var ArrayList = java.import('java.util.ArrayList');
    var list3 = new ArrayList();

I can see that I manage to add my project dependencies to it.

Any ideas of what can be wrong?

My log doesnt show much.

Im running this code on my test suite, but is just executing a .js file, nothing much

Hi everyone,

I manage to make it work with the import java.lang.System' and java.util.ArrayList

but still not able to make it work with my own .jar even the ones used on the examples folder.

java.classpath.push("lucene-core-6.0.0.jar");
java.classpath.push("lucene-analyzers-common-6.0.0.jar");
java.classpath.push("lucene-queryparser-6.0.0.jar");

var idx = java.newInstanceSync("org.apache.lucene.store.RAMDirectory");

Im getting this error:

var idx = java.newInstanceSync("org.apache.lucene.store.RAMDirectory");
               ^

Error: Could not create class org.apache.lucene.store.RAMDirectory

Make sure you add everything to the classpath before calling anything else in node-java. Also take a look at https://www.npmjs.com/package/node-java-maven I created this to easy the use of dependencies.

Hi @joeferner, thank you for the help. The only issue i'm having is that my repo is locally (I have a local gitlab), i add the repository on the index.js but i'm getting an error 401 (Unauthorized because the password and user).

Do you know if I can call the ./node_modules/.bin/node-java-maven pointing to another settings.xml adding a user and password for it ?

RenanChagas avatar Apr 24 '18 09:04 RenanChagas

Currently it only supports non-authenticated access. I've had that on my backlog of things to do for some time. It will look locally in .m2/repository first so if you have the dependencies local it should work, not sure the best way to bootstrap the .m2/repository until I get reading the settings.xml in though.

One of the reasons I mentioned the route of using node-java-maven is that Java happily ignores jars it can't find in the classpath. So one option might be to specify the full path of your jars to start just to make sure.

@joeferner Thank you for the reply !!

Im adding the java.push with the full path now, but I get an error everytime I try to instantiate a method.

Sorry to bother you again but do you mind checking if I missing something on the .js code ? ?

#!/usr/bin/env node

eyes.checkWindow(5, "teste");
