EOFException DataInputStream.readFully

Basically I'm helping a friend of mine out,
There's a disconnection error with his game (runescape private server) and there's an error that keeps being thrown, which is
DataInputStream.readFully(Unknown Source)
at Client.streamLoaderForName(Client.java:7343)
I read some things up on using while(in.available() > 0), but I don't know where it'd be placed.
This is the method where the error occurs
private CacheArchive streamLoaderForName(int i, String s, String s1, int j, int k)
{
byte abyte0[] = null;
int l = 5;
try
{
if(cacheIndices[0] != null)
abyte0 = cacheIndices[0].get(i);
}
catch(Exception _ex) { }
if(abyte0 != null)
{
CacheArchive streamLoader = new CacheArchive(abyte0);
return streamLoader;
}
int j1 = 0;
while(abyte0 == null)
{
String s2 = "Unknown error";
setLoadingText(k, "Requesting " + s);
Object obj = null;
try
{
int k1 = 0;
DataInputStream datainputstream = jaggrabRequest(s1 + j);
byte[] abyte1 = new byte[6];
datainputstream.readFully(abyte1, 0, 6);
Stream stream = new Stream(abyte1);
stream.currentOffset = 3;
int i2 = stream.read3Bytes() + 6;
int j2 = 6;
abyte0 = new byte[i2];
System.arraycopy(abyte1, 0, abyte0, 0, 6);
while(j2 < i2)
{
int l2 = i2 - j2;
if(l2 > 1000)
l2 = 1000;
int j3 = datainputstream.read(abyte0, j2, l2);
if(j3 < 0)
{
s2 = "Length error: " + j2 + "/" + i2;
throw new IOException("EOF");
}
j2 += j3;
int k3 = (j2 * 100) / i2;
k1 = k3;
}
datainputstream.close();
try
{
if(cacheIndices[0] != null)
cacheIndices[0].put(abyte0.length, abyte0, i);
}
catch(Exception _ex)
{
cacheIndices[0] = null;
}
}
catch(IOException ioexception)
{
ioexception.printStackTrace();
if(s2.equals("Unknown error"))
s2 = "Connection error";
abyte0 = null;
}
catch(NullPointerException _ex)
{
s2 = "Null error";
abyte0 = null;
}
catch(ArrayIndexOutOfBoundsException _ex)
{
s2 = "Bounds error";
abyte0 = null;
}
catch(Exception _ex)
{
s2 = "Unexpected error";
abyte0 = null;
}
if(abyte0 == null)
{
for(int l1 = l; l1 > 0; l1--)
{
if(j1 >= 3)
{
setLoadingText(k, "Game updated - please reload page");
l1 = 10;
} else
{
setLoadingText(k, s2 + " - Retrying in " + l1);
}
try
{
Thread.sleep(1000L);
}
catch(Exception _ex) { }
}
l *= 2;
if(l > 60)
l = 60;
}
}
CacheArchive streamLoader_1 = new CacheArchive(abyte0);
return streamLoader_1;
}
I can't seem to find out where to do any placements or how to fix this error. By the way, the line that's 7343, is
datainputstream.readFully(abyte1, 0, 6);
Also sorry for the poor thread, I don't know how to write it up properly on this.

Submit Hadoop Map Reduce Job With Secondary Data File?

I'm trying to do a Map-Reduce job on big text file which contains my data. To process this data I actually need another array to do lookup's with the data I'm processing.
So ideally the reducers would load this file and populate the array, then start reducing.
I'm trying to use Google Cloud platform because I get £250 free computation, Without going into massive detail about the project, I'm new to map-reduce, only having done a small university course on extreme computing and need a little direction for the best way to achieve this. There are a few things I haven't fixed yet like the output types etc but what I'm struggling with is the setup() function, exactly how to populate my array before the reducer starts reducing, any help would be greatly appreciated!

Error: A JNI error has occurred (javax.mail.jar)

I'm trying to read gmail messages using showmsg.java in the javamail sample package, and I keep getting this error when I run it. The program compiles fine though.

Unable To Cycle Backwards Through Android Notifications

I have a series of notifications which appear two at a time to display a series of a total of 6-10 instructions (depending on the results of a web service call.) This portion of the code is working fine. The problem is when clicking BACKWARDS through the notifications cycle (if you click any of the two displayed notifications it will display the previous two notifications) it gets hungup at step 5 and does not display the 5th notifications and I'm having a bit of trouble determining why.

Byte Array operations in objective-c like java?

I want to implement one functionality as my ANDROID colleague did. Below is code snippet and I am having trouble converting that code to objective-c. So please guide me in right direction--- Thanks
Here is the code snippet
public String createControlParams() {
controlParams_ = "";
String expiry = "";
String delayedDelivery = "";
String restricted = "";
String priorityIndicator = "";
String acknowledgement = "";
//Note - PMessage.PRIORITY_INDICATOR_WHITE is defined as Int like 1,2,3
if (priorityIndicator_ == PMessage.PRIORITY_INDICATOR_WHITE) {
expiryTimeText_ = "";
restrictBackup = false;
restrictForward_ = false;
readAcknowledgement_ = false;
}
if (expiryTimeText_ != null && expiryTimeText_.length() > 0) {
int exptime = Integer.parseInt(expiryTimeText_);
byte h = (byte) (exptime / 60);
byte m = (byte) (exptime % 60);
expiry = new String(new byte[]{'E', 0, h, m});//??? how to get this thing in objective-c
}
if (delayDelivery) {
long timeDifference;
long deliveryTime;
// Fix
// if (midlet_.getPlatform().equalsIgnoreCase("rim")) {
//// timeDifference = Calendar.getInstance().getTimeZone().getRawOffset();
//// deliveryTime = (dateField_.getTime() - (dateField_.getTime() % (24 * 60 * 60 * 1000))) + (24 * 60 * 60 * 1000) + deliverySetTime_ - timeDifference;//+timeDifference;//(((Integer) timeSpinner.getValue()).longValue() * 1000);
// deliveryTime = (dateField_.getTime() + deliverySetTime_);// - timeDifference;
// } else {
deliveryTime = dateField_.getTime() + deliverySetTime_;// - timeDifference;
// }
if (deliveryTime > (new Date().getTime() + 2000)) { // Added to_ make message as instant delivery as opposed to_ delayed delivery if the delivery time is set in past (Added 2 seconds for message processing time)

I'm not an Objective C guy, but have you tried using char? In C/C++ a char is one byte and should do what you need it to.

You don't need to use bytes. You can use an NSArray of NSStrings.
Bytes, or unsigned char's in C, are more useful when you are concerned about the memory size of some data in a constrained environment.
