FactoryConfigurationError thrown when trying to load jar from ByteArray with custom ClassLoader

I want to dynamically load JAR Files using a ClassLoader from a ByteArray. It works fine with every executable JAR Files I've tried it with so far, except a Program using WebLaF. I always get the following set of Errors:

After this, the JAR runs successfully until it has to load the GUI. Then it crashes with another error:
javax.xml.parsers.FactoryConfigurationError: Provider for class javax.xml.parsers.DocumentBuilderFactory cannot be created
My Code is the following:
public class ByteCodeClassLoader extends ClassLoader {
final Map<String, byte[]> classes;
final Map<String, byte[]> res;
-snip-
#Override
protected Class<?> findClass(String name) throws ClassNotFoundException {
byte[] code = classes.get(name);
if (code != null){
return defineClass(name, code, 0, code.length);
}
return super.findClass(name);
}
#Override
public URL getResource(String name) {
URL ur = ByteCodeClassLoader.class.getResource(name);
if (ur != null) {
return ur;
}
try {
return new URL(null, "bytes:///" + name, new BytesHandler());
} catch (MalformedURLException e) {
throw new RuntimeException(e);
}
}
#Override
public InputStream getResourceAsStream(String name) {
return new ByteArrayInputStream(res.get(name));
}
#Override
protected Enumeration<URL> findResources(String name) throws IOException {
throw new IOException("Cannot fetch URL out of res");
}
-snip-
If you know a solution to this issue, it would help me greatly. Even just a lead in the right direction would be awesome. I hope I supplied all the important information.

Connect to Athena using JDBC in a maven project

I'm trying to connect to the Amazon Athena, using jdbc in a maven project, but an exception is being raised. I think that the class is not being found. In Athena's guide it says:
Set the JDBC property, aws_credentials_provider_class, equal to the class name, and include itin your classpath. (1)
Since I'm using eclipse, I thought that the class would be already in the classpath, but apparently not. I tested the code in a simple java project (not maven) and it worked.
AmazonCredentialsProvider.java:
package athena;
import com.amazonaws.auth.AWSCredentials;
public class AmazonCredentials implements AWSCredentials {
#Override public String getAWSAccessKeyId() { return "..."; }
#Override public String getAWSSecretKey() { return "..."; }
}
AmazonCredentialsProvider.java:
package athena;
import com.amazonaws.auth.AWSCredentials;
import com.amazonaws.auth.AWSCredentialsProvider;
public class AmazonCredentialsProvider implements AWSCredentialsProvider {
#Override public AWSCredentials getCredentials() { return new AmazonCredentials(); }
#Override public void refresh() {}
}
The code snippet of the connection :
Class.forName("com.amazonaws.athena.jdbc.AthenaDriver");
Properties properties = new Properties();
properties.setProperty("user", user);
properties.setProperty("password", password);
properties.setProperty("aws_credentials_provider_class", "athena.AmazonCredentialsProvider");
Connection connection = DriverManager.getConnection("jdbc:awsathena://athena." + region + ".amazonaws.com:443", properties);
The exception:

Does anyone know how to solve it?

Are you using the latest version of the JDBC driver?
If yes, try to follow these instructions:

HashMap of HashMap of Generic Type serialization in Java

Fixed, per Engineer Dollery's answer, solution at bottom.
The goal is to serialize the network field of class Network. Sorry for the naming.
I had this, which compiled, and serialized properly.
public class Network {
private HashMap<String, HashMap<String, Number>> network;
...
public void load(String networkFile) throws Exception{
network = (HashMap<String, HashMap<String, Number>>)Utility.deserialize(Utility.load(networkFile));
}
public void save(String networkFile) throws Exception{
Utility.save(networkFile, Utility.serialize(network));
}
}
class Number implements Serializable {
...
}
I changed it to this generic version, which compiles, but no longer serializes. I need someway to specify that HashMap of T and Number is serializable.
public class Network<T extends Serializable> {
private HashMap<T, HashMap<T, Number>> network;
...
public void load(String networkFile) throws Exception{
network = (HashMap<T, HashMap<T, Number>>)Utility.deserialize(Utility.load(networkFile));
}
public void save(String networkFile) throws Exception{
Utility.save(networkFile, Utility.serialize(network));
}
}
class Number implements Serializable {
...
}
And this is the code for serialization
package Bullib;
import java.io.*;
import java.util.*;
import java.util.regex.*;
public class Utility{
public static Pattern phrasePattern = Pattern.compile("[^;:!.?]+");
public static Pattern wordPattern = Pattern.compile("['A-Za-z]+");
public static Object deserialize(byte[] serialized) throws Exception {
ByteArrayInputStream bi = new ByteArrayInputStream(serialized);
ObjectInputStream si = new ObjectInputStream(bi);
return si.readObject();
}
public static byte[] serialize(Object target) throws Exception {
ByteArrayOutputStream bo = new ByteArrayOutputStream();
ObjectOutputStream so = new ObjectOutputStream(bo);
so.writeObject(target);
so.flush();
return bo.toByteArray();
}
public static byte[] load(String filename) throws Exception {
RandomAccessFile file = new RandomAccessFile(new File(filename), "r");
byte[] b = new byte[(int)file.length()];
file.read(b);
file.close();
return b;
}
public static void save(String filename, byte[] value) throws Exception {
RandomAccessFile file = new RandomAccessFile(new File(filename), "rw");
file.write(value);
file.close();
}
public static Collection<String> executeRegex(Pattern pattern, String text){
LinkedList<String> matches = new LinkedList<String>();
Matcher m = pattern.matcher(text);
while (m.find()) {
matches.add(m.group(0));
}
return matches;
}
}
This is the error I get back when trying to serialize with T as either String or Double

Per requests, an example test and error. As you can see, it produces the same exception as above. I've updated the test to show that it passes if nothing is added to the map, and fails otherwise.
public static void main(String[] args) throws Exception{
Network<String> stringtest = new Network<String>("","","");
stringtest.save("testempty");
stringtest.load("testempty");
System.out.println("passed empty");

private HashMap<T, HashMap<T, Number>> network;
...
public void load(String networkFile) throws Exception{
network = (HashMap<T, HashMap<T, Number>>)Utility.deserialize(Utility.load(networkFile));
}
public void save(String networkFile) throws Exception{
Utility.save(networkFile, Utility.serialize(network));
}
}
class Number implements Serializable {
...
}
to
public class Network<T extends Serializable> implements Serializable {
private HashMap<T, HashMap<T, Number>> network;
...
public void load(String networkFile) throws Exception{
network = (HashMap<T, HashMap<T, Number>>)Utility.deserialize(Utility.load(networkFile));
}
public void save(String networkFile) throws Exception{
Utility.save(networkFile, Utility.serialize(network));
}
}
class Number implements Serializable {
...
}

Try this:
public class Network implements Serializable

Rhino reports missing : after property id

I'm using Rhino 1.7 R4 with envjs 1.2 on Mac OSX with JDK 1.6.0_33

Please help

Wladimir,
You were right it was a version thing.
It turns out that the batik libs I imported included another version of rhino.
By excluding batik-js from my project for each batik dependency this issue went away.

ServerException is being thrown while binding RMI service

I'm trying to build simple echo server as RMI application (step by step as it's described in Sun tutorial).
All source code is shown below, it's very simple:
package test;
import java.rmi.Remote;
import java.rmi.RemoteException;
public interface EchoServer extends Remote {
public String sendString (String str) throws RemoteException;
}
package test;
import java.rmi.server.UnicastRemoteObject;
import java.rmi.RemoteException;
public class EchoServerImpl extends UnicastRemoteObject implements EchoServer {
public EchoServerImpl () throws RemoteException {
super ();
}
public String sendString (String str) throws RemoteException {
return str.toUpperCase();
}
}
package test;
import java.rmi.Naming;
public class RMIServer {
public RMIServer () {
try {
EchoServer eServer = new EchoServerImpl ();
Naming.rebind ("rmi://localhost:1099/EchoService", eServer); // <--exception
} catch (Exception e) {
e.printStackTrace ();
}
}
public static void main(String[] args) {
new RMIServer ();
}
}
I compile code with rmic and I see file EchoServerImpl_Stub.class. After that I run 'rmiregistry' and then I start RMIServer. And at that moment I see ServerException:
java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:
java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is:

I think it's a common problem and it's probably connected with wrong deploying. How to fix it?

I think it's your rmiregistry classpath. The test.EchoServer interface needs to be accessible to the rmiregistry itself. Set your CLASSPATH environment variable before you run up the rmiregistry e.g.
C:\>set CLASSPATH="MyBinFolder"
C:\>rmiregistry
Also, rmic is a hangover from before Java 5. It isn't necessary to run it anymore. Just run your server and client as normal and the proxies will be created dynamically.
