Why do I get these errors at runtime? I'm using ESAPI-2.0.1.jar, I'm not trying to run it on a server. Just testing it in Eclipse. They are in my build path and in Referenced Libraries. Any help would be great. Thanks.

Not sure what to do.
It seems that you have a problem finding the Log4j.jar (org.apache.log4j)

My Code was working with org.owasp.esapi 2.2.0.0 but after upgrading to 2.2.3.1 I am getting ClassNotFoundException.
My Code is something like:
Properties esapiProps = new Properties();
try {
esapiProps.load( SecurityUtil.class.getResourceAsStream("/ESAPI.properties") );
} catch (IOException | NullPointerException e) {
logger.log(Level.SEVERE, "esapi Exception: ", e);
}
ESAPI.override( new DefaultSecurityConfiguration(esapiProps));
// ----- Then canonicalize an input -----
ESAPI.encoder().canonicalize(input);
I read the release notes and added some properties and esapi-java-logging
my ESAPI.properties (in class path)
ESAPI.printProperties=true

You said that you read the release notes. The reason for your problem is a detail that you missed that was documented there. Look in those release notes, in the section labeled:
*** IMPORTANT WORKAROUND for 2.2.1.0 ESAPI Logging ***
There, it states:
Lastly, if you try to use the new ESAPI 2.2.1.0 logging, you will notice that you need to change ESAPI.Logger and also possibly provide some other logging properties as well. This is because the logger packages were reorganized to improve maintainability, but we failed to mention it. To use ESAPI logging in ESAPI 2.2.1.0 (and later), you MUST set the ESAPI.Logger property to one of:
org.owasp.esapi.logging.java.JavaLogFactory - To use the new default, java.util.logging (JUL)
org.owasp.esapi.logging.log4j.Log4JLogFactory - To use the end-of-life Log4J 1.x logger
org.owasp.esapi.logging.slf4j.Slf4JLogFactory - To use the new (to release 2.2.0.0) SLF4J logger
Between that and a careful reading of your exception stack trace:
... deleted...
Caused by: org.owasp.esapi.errors.ConfigurationException: java.lang.ClassNotFoundException: org.owasp.esapi.reference.JavaLogFactory LogFactory class (org.owasp.esapi.reference.JavaLogFactory) must be in class path.
... 17 more
Caused by: java.lang.ClassNotFoundException: org.owasp.esapi.reference.JavaLogFactory
...deleted...
I think that should explain the reason. Those classes were reorganized to different packages to accommodate SLF4J logging.
There is some typo with logger factory config in ESAPI.properties. The classes are in org.owasp.esapi.logging.*.
#ESAPI.Logger=org.owasp.esapi.logging.log4j.Log4JLogFactory
#ESAPI.Logger=org.owasp.esapi.logging.slf4j.Slf4JLogFactory
ESAPI.Logger=org.owasp.esapi.logging.java.JavaLogFactory

File file ;
try {
file = (new File("Agent.jar"));
ByteBuddyAgent.attach(file,"18467");

Any suggestion on this!!
As for the first error message: does the target VM run the attachment listener? You can try to force starting the thread by setting -XX:+StartAttachListener which should be set by default. What JVM version are you running?
The other error message indicates that the attachment library was already loaded by another class loader. See this answer for further details: java.lang.UnsatisfiedLinkError: Native Library XXX.so already loaded in another classloader
I just ran a hdfs demo like this:

fs.create(new Path("/tmp/test"));
fs.delete(new Path("/tmp/test"), false);
fs.close();
}
}

When I removed fs.close();, it worked well.
The environment is:
hadoop-core -- 1.2.1
jdk -- 1.6.0_21
What happened when filesystem closed?
Anyone has encountered this problem?
Generally, you should not call fs.close() when you do a FileSystem.get(...).
FileSystem.get(...) won't actually open a "new" FileSystem object. When you do a close() on that FileSystem, you will close it for any upstream process as well.
For example, if you close the FileSystem during a mapper, your MapReduce driver will fail when it again tries to close the FileSystem on cleanup.

I think there must be problem with this
org.apache.neethi.PolicyEngine.getPolicy(Ljava/lang/Object;)Lorg/apache/neethi/Policy;
or may be im wrong. Either way, dunno how to fix. Would be of much help if anyone knew of faced/solved this before.
I got this while making following call:
public String getAppDeclWrapper(String session, String parentAgent, String mirsTxnNo, String strReason, String isApprove, String modifiedBY){
String returnString = null;
try {
mtmrsLogger.info("Entering into Approve Decline procedure, Starting to send Status to MIRS");
MIRSRemittanceServicesStub stub = new MIRSRemittanceServicesStub(); //Error occurs at this line
ApproveDecline approvedEcline = new ApproveDecline();
ApproveDeclineResponse approveResponse = new ApproveDeclineResponse();
approvedEcline.setCParentAgent(parentAgent);
approvedEcline.setMirsSession(session);
approvedEcline.setModifiedBy(modifiedBY);
approvedEcline.setRefNo(mirsTxnNo);
approvedEcline.setStrReason(strReason);
approvedEcline.setIsApprove(isApprove);
My guess is you have multiple versions (or invalid version) of PolicyEngine on your classpath. I think you are running inside a servlet engine. Try following code to determine where this version is stored and fix it:
org.apache.neethi.PolicyEngine.class.getProtectionDomain().getCodeSource().getLocation()
I am having a problem setting up a simple RMI server, and was wondering if someone can point me in the right direction.
I have a simple class, Server, that should export an simple interface. Currently when I try and run the server class, I get the following exception:
java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:
java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is:
java.lang.ClassNotFoundException: prototype.ISimpleService
I have already made sure that the rmi registry is running, by running the "start rmiregistry" command, and I am running the service with the following argument
-Djava.rmi.server.codebase=file:C:/Users/John/Documents/NetBeansProjects/Prototype/build/classes
The path in the argument above points to the top level folder of my class hierarchy, so:
/classes
/prototype
->ISimpleService.class
->SimpleServiceImpl.class
->IServer.class
Here is my server code:
public class Server
{
private static ISimpleService service;
public static void main(String[] args)
{
service = new SimpleServiceImpl();
try
{
ISimpleService stub = (ISimpleService) UnicastRemoteObject.exportObject(service, 0);
Registry registry = LocateRegistry.getRegistry();
registry.rebind("SimpleService", stub);
System.out.println("Simple Service bound");
}
catch (Exception ex)
{
System.out.println("Exception binding the simple service");
ex.printStackTrace();
}
}
}
I have looked at the Java RMI trail, and adapted my simple example to follow that, although I am not using security/permissions that I shouldn't need as I have gotten an RMI example working before without that stuff...
So I believe I have to missing something simple(no pun intended), to make this work, but I cant see anything at the moment.
Do anyone have an ideas?

I have solved this issue... Took me alittle longer than I expected though :(
Turns out when you use a codebase argument like I had done, you should place a trailing "/" at the end, if you are pointing to a directory. Once I added that in, my server successfully binds.
For a resource on this p see http://download.oracle.com/javase/1.4.2/docs/guide/rmi/codebase.html#section6
It seems prototype.ISimpleService is not in your classpath.
Try:
java -cp=C:/Users/John/Documents/NetBeansProjects/Prototype/build/classes;C:/Users/John/Documents/NetBeansProjects/Server/build/classes Server
