I know this is an error that occurs inside onSuccess, but I don't know how to fix it. Help.
check runtime permission for Android. May be this is an issue of permission and due to that you are not able to get location value.

When following Cubicoder's modding tutorial for Forge 1.12.2, and creating my first item, the texture for the item will not load. I have double checked all of my code against his code. I have my latest log here. I have my registration handler RegistrationHandler.java down below.
package notacyborg.tutorialmod;

}
private static void registerModel(Item item, int meta)
{
ModelLoader.setCustomModelResourceLocation(item, meta,
new ModelResourceLocation(item.getRegistryName(), "inventory"));
}
}
And my first_item.json model file.
{
"parent": "item/generated",
"textures": {
"layer0": "tutorialmod:textures/items/first_item"
}
}
Any help is appreciated!
Your error log says that it was not able to find the model file of your first_item. Make sure that you have put your first_item.json (model file) in assets/Your-Mod-ID/models/item/first_item.json
In your first_item.json file, line 4 should be:
"textures": {
"layer0": "tutorialmod:item/first_item"
}
Try it out and post an error log too if you encounter any further errors.
I would like the player to pickup the Custom Arrow not an normal arrow.
I think its something to do with an ItemStack is this possible to do in Minecraft 1.12.2?
My arrow class called CustomArrow:

public class LevitationArrow extends ItemArrow {
public LevitationArrow(String Name) {
this.setCreativeTab(CreativeTabs.COMBAT);
this.setRegistryName(Name);
this.setUnlocalizedName(Name);
RegisterItems.ITEMS.add(this);
}
public ECustomArrow makeTippedArrow(World world, ItemStack itemstack, EntityLivingBase shooter) {
return new ECustomArrow(world, shooter);
}
}
Arrow entity called ECustomArrow
package domain.entity;
import domain.Utils;
import net.minecraft.entity.EntityLivingBase;
import net.minecraft.entity.projectile.EntityArrow;
import net.minecraft.init.MobEffects;
import net.minecraft.potion.PotionEffect;

super.arrowHit(living);
if (living != shootingEntity) {
living.addPotionEffect(new PotionEffect(MobEffects.***EFFECT NAME***, Utils.SECS2TICKS(10), 1));
}
}
}
In my main items class i got

can anyone give me some advice to find the reason.
That is really odd thing to happen. Please read the code for two classes.
https://github.com/openjdk-mirror/jdk7u-jdk/blob/master/src/share/classes/java/lang/AbstractStringBuilder.java
https://github.com/openjdk-mirror/jdk7u-jdk/blob/master/src/share/classes/java/lang/StringBuffer.java
AbstractStringBuilder has constructor with no args which doesn't allocate the field 'value', which makes accessing the 'value' field being NPE. Any constructors in StringBuffer use that constructor. So maybe some odd thing happens in serialization/deserialization and unfortunately 'value' field in AbstractStringBuilder is being null.
Maybe initializing totalCmds in prepare() would be better, and also you need to consider synchronization (thread-safety) between bolts. prepare() can be called per bolt instance so fields are thread-safe, but class fields are not thread-safe.
I think I find the problem maybe;
the key point is
"StringBuffer _totalCmds = new StringBuffer(totalCmds);" and " totalCmds.append(lastCommands);//line 61"
when new a object, It takes serval steps:
(1) allocate memory and return reference
(2) initialize
if append after (1) and before (2) then the StringBuffer.java extends AbstractStringBuilder.java
/**
* The value is used for character storage.
*/
char[] value;
value is not initialized;so this will get null:
#Override
public synchronized void ensureCapacity(int minimumCapacity) {
if (minimumCapacity > value.length) {
expandCapacity(minimumCapacity);
}
}
this blot has a another question, some data maybe lost under a multithreaded environment
I want to ask that is there a way to do Pretty formatting in xtext automatically without (ctrl+shift+f) or turning it on from preference menu. What I actually want is whenever a user completes writing the code it is automatically pretty formatted (or on runtime) without (ctrl+shift+f).
There is a way for doing that which is called "AutoEdit". It's not exactly when the user completes writing but it's with every token. That's at least what I have done. You can for sure change that. I will give you an example that I implemented myself for my project. It basically capitalizes everykeyword as the user types (triggered by spaces and endlines).
It is a UI thing. So, In your UI project:
in MyDslUiModule.java you need to attach your AutoEdit custom made class do that like this:
public Class<? extends DefaultAutoEditStrategyProvider> bindDefaultAutoEditStrategyProvider()
{
return MyDslAutoEditStrategyProvider.class;
}
Our class will be called MyDslAutoEditStrategyProvider so, go ahead and create it in a MyDslAutoEditStrategyProvider.java file. Mine had this to do what i explained in the introduction:
import java.util.Set;
import org.eclipse.jface.text.DocumentCommand;
import org.eclipse.jface.text.IAutoEditStrategy;
import org.eclipse.jface.text.IDocument;
import org.eclipse.jface.text.IRegion;
import org.eclipse.xtext.GrammarUtil;
import org.eclipse.xtext.IGrammarAccess;
import org.eclipse.xtext.ui.editor.autoedit.DefaultAutoEditStrategyProvider;
import org.eclipse.xtext.ui.editor.model.XtextDocument;
import com.google.inject.Inject;
import com.google.inject.Provider;
public class MyDslAutoEditStrategyProvider extends DefaultAutoEditStrategyProvider {
#Inject
Provider<IGrammarAccess> iGrammar;
private Set<String> KWDS;
#Override
protected void configure(IEditStrategyAcceptor acceptor) {
KWDS = GrammarUtil.getAllKeywords(iGrammar.get().getGrammar());
IAutoEditStrategy strategy = new IAutoEditStrategy()
{
#Override
public void customizeDocumentCommand(IDocument document, DocumentCommand command)
{
if ( command.text.length() == 0 || command.text.charAt(0) > ' ') return;
IRegion reg = ((XtextDocument) document).getLastDamage();
try {
String token = document.get(reg.getOffset(), reg.getLength());
String possibleKWD = token.toLowerCase();
if ( token.equals(possibleKWD.toUpperCase()) || !KWDS.contains(possibleKWD) ) return;
document.replace(reg.getOffset(), reg.getLength(), possibleKWD.toUpperCase());
}
catch (Exception e)
{
System.out.println("AutoEdit error.\n" + e.getMessage());
}
}
};
acceptor.accept(strategy, IDocument.DEFAULT_CONTENT_TYPE);
super.configure(acceptor);
}
}
I assume you saying "user completes writing" can be as "user saves file". If so here is how to trigger the formatter on save:
in MyDslUiModule.java:
public Class<? extends XtextDocumentProvider> bindXtextDocumentProvider()
{
return MyDslDocumentProvider.class;
}
Create the MyDslDocumentProvider class:
import org.eclipse.core.runtime.CoreException;
import org.eclipse.core.runtime.IProgressMonitor;
import org.eclipse.jface.text.IDocument;
import org.eclipse.ui.PlatformUI;
import org.eclipse.ui.handlers.IHandlerService;
import org.eclipse.xtext.ui.editor.model.XtextDocumentProvider;
public class MyDslDocumentProvider extends XtextDocumentProvider
{
#Override
protected void doSaveDocument(IProgressMonitor monitor, Object element, IDocument document, boolean overwrite)
throws CoreException {
IHandlerService service = (IHandlerService) PlatformUI.getWorkbench().getService(IHandlerService.class);
try {
service.executeCommand("org.eclipse.xtext.ui.FormatAction", null);
} catch (Exception e)
{
e.printStackTrace();
}
super.doSaveDocument(monitor, element, document, overwrite);
}
}
I've just started evaluating Neo4j to see how well its fits our use case.
I'm using the embedded Java API to insert edges and nodes into a graph.
After creating around 5000 nodes I get the following error (using Neo4j 2.1.6 and 2.1.7 on OS X Yosemite)
org.neo4j.graphdb.TransactionFailureException: Unable to commit transaction
Caused by: javax.transaction.xa.XAException
Caused by: org.neo4j.kernel.impl.nioneo.store.UnderlyingStorageException: java.io.FileNotFoundException: /Users/mihir.k/IdeaProjects/Turant/target/neo4j-hello-db/schema/label/lucene/_8zr.frq (Too many open files)
Caused by: java.io.FileNotFoundException: /Users/mihir.k/IdeaProjects/Turant/target/neo4j-hello-db/schema/label/lucene/_8zr.frq (Too many open files)
I've looked at numerous similar StackOverFlow questions and other related threads online. They all suggest increasing the max open files limit.
I've tried doing that.
These are my settings:
kern.maxfiles: 65536
kern.maxfilesperproc: 65536
However this hasn't fixed the error.
While the Neo4j code runs I tried using the lsof|wc -l command. The code always breaks when around 10000 files are open.
The following is the main class that deals with Neo4j:
import java.io.File;
import java.io.Serializable;

{
Runtime.getRuntime().addShutdownHook( new Thread()
{

}
}
There is another Neo4jAdapter class that is used to implement domain specific logic. It uses the Neo4jDB class to do add/update nodes/properties/relationships
import org.apache.lucene.index.IndexWriter;
import org.codehaus.jackson.map.ObjectMapper;
import org.json.*;
import org.neo4j.graphdb.*;
import org.neo4j.graphdb.factory.GraphDatabaseFactory;
import org.neo4j.graphdb.schema.IndexDefinition;
import java.io.*;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;
import java.util.Set;
public class Neo4jAdapter implements Serializable {
static Neo4jDB n4j = new Neo4jDB();
public static GraphDatabaseService db = Neo4jDB.db ;
public void begin() {
n4j.startDbInstance();
}
public static void main(String[] args) {}
public String graphPut(String jsonString) {
System.out.println("graphput called");
HashMap<String, Object> map = jsonToMap(jsonString); //Json deserializer
Node startNode = n4j.createOrGetNode(...);
Node endNode = n4j.createOrGetNode(...);
propertyMap = new HashMap<String, Object>();
propertyMap.put(....);
try (Transaction tx = Neo4jDB.db.beginTx()) {
Relationship relationship = startNode.getSingleRelationship(...);
if (relationship != null) {
Integer currentCount = (Integer) relationship.getProperty("count");
Integer updatedCount = currentCount + 1;
propertyMap.put("count", updatedCount);
} else {
Integer updatedCount = 1;
propertyMap.put("count", updatedCount);
}
tx.success();
}
n4j.createOrUpdateRelationship(RelationshipsUser360.BLAH, startNode, endNode, propertyMap);
}
}
}
return "Are you sponge worthy??";
}
}
Finally, there is a Sprak App that calls the "graphput" method of the Neo4jAdapter class. The relevant code snippet is (the following is scala+spark code) :
val graphdb : Neo4jAdapter = new Neo4jAdapter()
graphdb.begin()
linesEnriched.foreach(a=>graphdb.graphPutMap(a))
where 'a' is a json string and linesEnriched is a Spark RDD (basically a set of strings)
