I'm new to NativeScript and I'd like to fetch a JSON that is a part of my projet.
How do I do so?
The following failed:
app/data/util.js
import json from "../data/urls"; // Attempting to fetch urls.json
As a result:
com.tns.NativeScriptException: Error calling module function
Error: Cannot find module '../data/urls'

No matter if I attempt to fetch ~/data/urls or ../data/urls, the error is the same (with the minor path difference)
Later on, I ran into this question, but I'm pretty sure that there's a simpler to way to fetch a JSON of the current project, right?
you should determine the file extension too,
so it should be like:
import json from "../data/urls.json";

I have a 3 node Apache Ignite Cluster, I have created a cache with Integer as Key and a 'Subscriber' POJO as value, when I connect to the cluster from inside a JAVA program and access the cache , I get the above mentioned exception, I have 'peerclassloading' property set to false, and I have deployed 'Subscriber' POJO Binaries in all the nodes, Please find the complete stack trace below. What am I missing here? Why is it looking for some file inside my IGNITE_HOME when I am starting client inside my JAVA program with Ignition.start()?

Looks like the cache tries to deserialize the value after retrieving it from cache, but you don't have a class for it on the node where IgniteCache.get() was called. You can either deploy the class, or use IgniteCache.withKeepBinary() to avoid deserialization: https://apacheignite.readme.io/docs/binary-marshaller#binaryobject-cache-api
The issue turned out to be pretty simple, Ignite looks for the user defined POJOs from the list of classes loaded by default class loader, if it does not find it there , it looks inside marshalled classes, In my case, my value POJO was inside the test resources , hence default class loader was not loading the class, causing ignite to look inside marshalled classes folder(IGNITE_HOME/work/marshaller/) .
I'm getting this error when trying to run a select after connecting to Hive.
Is this a bad jar file?

There is a calls in hive jdbc jar called org.apache.hive.jdbc.HiveResultSetMetaData . This class contains a method isWritable which is not supported by hive yet. This is the reason why you get the error "Method not supported".
Take the source code of this class and update the above method. Then generate the class and replaced it in the jar. This worked for me.
I'm executing this simple code in a pig script:
REGISTER /home/myuser/mongodb/mongo-2.10.1.jar

set mapred.map.tasks.speculative.execution false;

col = LOAD 'mongodb://localhost:27017/mydb.mycollection' using com.mongodb.hadoop.pig.MongoLoader ('id:chararray, companyId:chararray, ts:chararray', 'id');
STORE col INTO 'mongodb://localhost:27017/mydb.mycollection2' USING com.mongodb.hadoop.pig.MongoInsertStorage ('', '');
it returns the following error:

I don't know where is the error so that mongodb protocol string "mongodb://" is well-written.
I have a similar issue when running LOAD and STORE using mongo-hadoop on the same Pig script.
It throws

I didn't investigate further, but either is a bug or some parameter related to locking. I don't know.
If I run the same code, but loading and storing in different scripts it runs without a problem.
I created a "AppProp.java" file to write 3 properties(dabase hostname,dbuser name,dbpassword) in "config.properties".I tried load properties file from classpath.but it gives error as following ....
**Exception in thread "main" java.lang.NullPointerException

at java.util.Properties.load0(Properties.java:353)
at java.util.Properties.load(Properties.java:341)
at App.main(App.java:18)**
Now,I want to know why it gives error?
For a project I'm working on I need to change some property values at run time and save them. Looking for a solution I found the apache commons configuration.
I have looked at some others topics solving my first problems but now, an error that says:
org.apache.commons.configuration.ConfigurationException: Unable to load the configuration from the URL file:/C:/Users/sensor/Documents/NetBeansProjects/HermanWijn/dist/run1776677076/HermanWijn.jar!/Database/DataProptester.properties
Looking at this toppic: Property file not reflecting the modified changes using Apache Commons Configuration
My code should be working but for some reason I get an error.
The JDBCWijnDAO is a class in the same package as the properties file, Of course I want to do more than just load the prop file, but at the moment when creating the new propconfig, gives an error which I need to solve.
code:
URL resource = JDBCWijnDAO.class.getResource("DataProptester.properties");
PropertiesConfiguration config = new PropertiesConfiguration(resource.getPath());
Okay, i think i "know" what the problem is but I don't really know how to fix it, in the trace there is a:
Caused by: java.io.FileNotFoundException: C:\Users\Sensor\Documents\NetBeansProjects\HermanWijn\dist\run1776677076\HermanWijn.jar!\Database\DataProptester.properties (The system cannot find the path specified)
I assume there is something wrong with the total path.
errors:
org.apache.commons.configuration.ConfigurationException: Unable to load the configuration from the URL file:/C:/Users/Sander/Documents/NetBeansProjects/HermanWijn/dist/run1776677076/HermanWijn.jar!/Database/DataProptester.properties
