Im getting this Exception with my project,after I run the project X times, I get it, but it is not always in the same class, sometimes it happens with other classes, or being more especific, with other frames, as far as I have seen, I have got it only with my frames.
when I get this error, I only retype the package of the frame that throws the exception and done!, but of course, that is not a solution.

This is my ans
Try it that will be helpful.

I am trying to build and consume a neo4j DB. Below, is the code which Im using to create a DB.
String graphDbPath = "C:/Users/abcd/parseJSON2GraphDB";
GraphDatabaseFactory dbFactory = new GraphDatabaseFactory();
GraphDatabaseService graphDb = dbFactory.newEmbeddedDatabase(graphDbPath);
try (Transaction tx = graphDb.beginTx()) {
// Perform DB operations
Node javaNode = graphDb.createNode();
javaNode.setProperty( "name", "Duane" );
Node scalaNode = graphDb.createNode();
scalaNode.setProperty( "name", "Nickull" );
tx.success();
}
graphDb.shutdown();
System.out.println("Created Successfully");
The error which I get when running it is :

Any pointers as to what is causing it?
From quick searches, I tried few solutions:
1) Check if any instances of Neo4J already running.
2) Changed the neo4j version (via maven)
Nothing has worked until now.
The stacktrace clearly mentions
java.lang.ClassNotFoundException: org.apache.lucene.codecs.lucene54.Lucene54Codec
So be sure to have lucene-analyzers-common-5.5.0.jar, lucene-codecs-5.5.0.jar and lucene-core-5.5.0.jar on your classpath. (assuming you're on Neo4j 3.0.x)
Or, as a more easy one use http://mvnrepository.com/artifact/org.neo4j/neo4j/3.0.6 as your single dependency which should pull in all other required dependencies transitively.
So i need to draw some small .gif pictures with the help of StdDraw (it MUST be StdDraw), but im running into an really stupid error. My Code is:
while(true){
StdDraw.setXscale(-R,R);
StdDraw.setYscale(-R,R);
StdDraw.picture(0, 0, "starfield.jpg");
}
where R is a Double and starfield.jpg is the Background Picture.
The Error i get when trying to run this is:

And because of this beeng a really huge error, i could not find any solution via Google, and i cant find the error myself. So if anyone can point me in the righ direction, this would be great!
I added the stdlib.jar as External Archive as described in this Video: https://www.youtube.com/watch?v=taJovOCBPS4
Okay, found the solution, I needed to export my code as Runnable JAR, after that it worked as expected.
The application is modular plug-in architecture. That is, while the work is done dynamically load classes. For this purpose a custom class loader extends ClassLoader.
The essence of the problem is that in Eclipse application runs, while in terminal (ubuntu) using the following line of code (where the Catalog "m /" indicates the location of the modules * .class):
java -jar ModularApp.jar m/
I get the following message:

Here's a snippet of code, the user class loader (extending ClassLoader), where there is an error:
protected Class<?> findClass(String className) throws ClassNotFoundException
{
try
{
byte b[]=getClassAsBytes(m_pathToBin+className+".class");
return (defineClass(className, b, 0, b.length));
}
catch(FileNotFoundException ex)
{
m_log.debug("Run of the System Classloader.");
return (super.findClass(className));
}
catch(IOException ex)
{
m_log.debug("Run of the Bootstrap.");
return (super.findClass(className));
}
}
What could be the problem?
P.S. Loader implemented on the basis of this article:
http://sysmagazine.com/posts/104229/
Look: The stack trace shows the message "Run of the System Classloader", which proves that the first catch was executed. This was caused by a FileNotFoundException, which clearly occurred in the getClassAsBytes method: This is what you must investigate: Find out what file you are trying to read (put a trace showing the the absolute path), and why that file does not exist.
(Eventually, that catch block tries to load the required class by the system classloader, which has no acces to that class, and so, it throws the ClassNotFoundException).

Thank you
I would need to see the full config and how you set up the tables for a better answer. Just looking at the error it seems like you are missing some hadoop jars on your classpath
I'm new to flexjson.
I tried the following java code for my test: "FlexjsonTest.zip".
The result of running the program is in "Protocol.txt".
I ran the code from the command line:
javac FlexjsonTest.java
java Flexjson
I use flexjson 2.1 .
Using Java 6 or Java 7 doesn't make any difference.
The result is always:

So, what am I doing wrong?
igel
it seems that you're trying to deserialize a JSON into an object called Address but the class Address seems not to be in your classpath
at flexjson.JSONDeserializer.deserialize(JSONDeserializer.java:158)
at FlexjsonTest.<init>(FlexjsonTest.java:22)

also, you should post the code that actually throws this stacktrace in your question
