--------------------------------------------------------------------------------------------------------------

2.1 - Step 1 - Signlink.java
Open up Signlink.java and search for findcachedir() and replace that method with this one:



replace yourclientname with the name of your client. For example: C:/.ricscape_file_store_32/
Save signlink.java and close it.

--------------------------------------------------------------------------------------------------------------

2.2 - Step 2 - Client.java
Open up client.java and search for Class44 method67 and replace that method with this one:

private Class44 method67(int i, String s, String s1, int j, byte byte0, int k)
	  {
	    byte abyte0[] = null;
	    int l = 5;
	    try
	    {
	      if(aClass14Array970[0] != null)
	      {
	        abyte0 = aClass14Array970[0].method233(true, i);
	      }
	      if(abyte0 == null)
						      {
							method13(15, (byte)4, "Downloading Cache");
downloadcache("YOUR CACHE URL LINK HERE", "cache.zip", "", "cache");		      
}
if(aClass14Array970[0] != null)
	      {
	        abyte0 = aClass14Array970[0].method233(true, i);
	      }
	    }
	    catch(Exception exception) { }
	    if(abyte0 != null);
	    if(abyte0 != null)
	    {
	      Class44 class44 = new Class44(44820, abyte0);
	      return class44;
	    }
	    int i1 = 0;
	    do
	    {
	      if(abyte0 != null)
	      {
	        break;
	      }
	      String s2 = "Unknown error";
	      method13(k, (byte)4, "Client updated - please reload client");
	      //method13(k, (byte)4, (new StringBuilder()).append("Requesting ").append(s).toString());
	      Object obj = null;
	      try
	      {
	        int j1 = 0;
	        DataInputStream datainputstream = method132((new StringBuilder()).append(s1).append(j).toString());
	        byte abyte1[] = new byte[6];
	        datainputstream.readFully(abyte1, 0, 6);
	        Class30_Sub2_Sub2 class30_sub2_sub2 = new Class30_Sub2_Sub2(abyte1, 891);
	        class30_sub2_sub2.anInt1406 = 3;
	        int l1 = class30_sub2_sub2.method412() + 6;
	        int i2 = 6;
	        abyte0 = new byte[l1];
	        for(int j2 = 0; j2 < 6; j2++)
	        {
	          abyte0[j2] = abyte1[j2];
	        }

	        while(i2 < l1)
	        {
	          int k2 = l1 - i2;
	          if(k2 > 1000)
	          {
	            k2 = 1000;
	          }
	          int l2 = datainputstream.read(abyte0, i2, k2);
	          if(l2 < 0)
	          {
	            s2 = (new StringBuilder()).append("Length error: ").append(i2).append("/").append(l1).toString();
	            throw new IOException("EOF");
	          }
	          i2 += l2;
	          int i3 = (i2 * 100) / l1;
	          if(i3 != j1)
	          {
	            method13(k, (byte)4, (new StringBuilder()).append("Loading ").append(s).append(" - ").append(i3).append("%").toString());
	          }
	          j1 = i3;
	        }
	        datainputstream.close();
	        try

	      }
	      catch(ArrayIndexOutOfBoundsException arrayindexoutofboundsexception)
	      {
	        s2 = "Bounds error";
	        abyte0 = null;
	        if(!signlink.reporterror)
	        {
	          return null;
	        }
	      }
	      catch(Exception exception1)
	      {

	          }
	          try
	          {

	          }
	          catch(Exception exception2) { }
	        }

	        l *= 2;

	        aBoolean872 = !aBoolean872;
	      }
	    } while(true);
	    Class44 class44_1 = new Class44(44820, abyte0);
	    if(byte0 != -41)
	    {
	      throw new NullPointerException();
	    } else
	    {
	      return class44_1;
	    }
  }

Replace the following:
YOUR CACHE URL LINK HERE
cache.zip
which is in this line:
downloadcache("YOUR CACHE URL LINK HERE", "cache.zip", "", "cache");
You only replace what's in the first 2 quotes.

The first quote is your link.
Your cache link must end with .zip
For example:
http://yoursite.com/cache.zip

The second quote is the extraction so it would like this:
"cache.zip"
Unless your zip file has a different name. If it does then you would put:
"zipfilename.zip"

This is the most important method and without it your client will not download the cache.
On top of Class44 method67 put this:

/*

*/
    public String name;
    public String dir;

public void downloadcache(String url, String name1, String dir1, String type)
    {
        dir = dir1;
        name = name1;
        try
        {
            URLConnection connection = (new URL(url)).openConnection();
            String f[] = url.split("/");
            File file = new File(f[f.length - 1]);
            int length = connection.getContentLength();
            InputStream instream = connection.getInputStream();
            try{new File(signlink.findcachedir()+dir).mkdir();}catch(Exception e){}
            FileOutputStream outstream = new FileOutputStream(signlink.findcachedir()+dir+file);
            int size = 0;
            int copy;
            byte[] buffer = new byte[4096];
            while((copy = instream.read(buffer)) != -1)
            {
                outstream.write(buffer, 0, copy);
                size+= copy;
                int percentage = (int)(((double)size / (double)length) * 100D);
                method13(percentage, (byte)4, "Downloading Cache - "+percentage+"%");
            }
            if(length != size)
            {
                instream.close();
                outstream.close();
            } else
            {
                method13(5, (byte)4, "Unpacking files...");
                instream.close();
                outstream.close();
                unZipFile();
                deleteFile();
                method13(10, (byte)4, "Unpacking was complete");
            }
        }
        catch(Exception e)
        {
            System.err.println("Error connecting to server.");
            e.printStackTrace();
        }
    }
    public void writeStream(InputStream In, OutputStream Out) throws IOException
    {
        byte Buffer[] = new byte[4096];
        int Len;
        while((Len = In.read(Buffer)) >= 0)
        {
            Out.write(Buffer, 0, Len);
        }
        In.close();

            for(Enumeration Entries = ZipFile.entries(); Entries.hasMoreElements();)
            {
                ZipEntry Entry = (ZipEntry)Entries.nextElement();
                if(Entry.isDirectory())
                {
                    (new File(signlink.findcachedir()+dir+Entry.getName())).mkdir();
                } else
                {
                    writeStream(ZipFile.getInputStream(Entry), new BufferedOutputStream(new FileOutputStream(signlink.findcachedir()+dir+Entry.getName())));
                }
            }
            ZipFile.close();
        }
        catch(Exception e)
        {

        catch(Exception e)
        {
            e.printStackTrace();
        }
    }

Once you have added those method's in your client.java, scroll all the way up still you see import's then add the following under the rest of them.

import java.awt.Dimension;
import java.net.URL;
import java.net.URLConnection;
import javax.swing.*;
import java.util.Enumeration;
import java.util.zip.ZipEntry;
import java.util.zip.ZipFile;

--------------------------------------------------------------------------------------------------------------

2.3 - Step 3 - Class30_Sub2_Sub1_Sub1.java(Sprites)
Now for the sprite part. Which most people don't do right.
Open up Class30_Sub2_Sub1_Sub1.java and replace all:

with this

Like this:

Do the same for the background

Once you have changed the location your client reads the sprites from your gonna wanna save the file and close it.

--------------------------------------------------------------------------------------------------------------

2.4 - Jarring and Signing
Before we start make sure you have downloaded the jar maker.(link located on top)
If you have already downloaded it then run the jar maker and watch this video.

Jarring and signing video: http://www.youtube.com/watch?v=9obXgxm_9qY&fmt=18

Once you have jarred and signed the client do the following:
Put the cache files(Everything inside the cache folder) and sprite "folder" together in a zip file.

To understand what i mean watch this video:
Cache + Sprites/Background Zipping:
Youtube: http://www.youtube.com/watch?v=KUPvCEObZuk

--------------------------------------------------------------------------------------------------------------

2.5 - Webclient Web Page

Replace yourclientname with the name of your client.

--------------------------------------------------------------------------------------------------------------

2.6 - End of tutorial details
This is what your webclient should do if you did this tutorial right:
http://www.youtube.com/watch?v=4wzI6JJP-Ds&fmt=22

--------------------------------------------------------------------------------------------------------------

Section 3 - Extra
3.1 - Frequently Asked Questions
Question: What's a good file host for my cache?
Answer: You can use any host that allows direct linking. Here are some that allow direct linking:
http://www.hotlinkfiles.com/
http://www.fileden.com/

Question: it's too hard. Can you make it for me?
Answer: No, I don't do this for people anymore. You gotta learn how to make a webclient for when you update your client.

Question: I have found a error or a misspelled word on your tutorial, what do I do?
Answer: Send me a private message with the error or misspelled word.

Question: The java console says it cannot find client.class, What should I do?
Answer: I recommend deleting all the class files and recompile your client.

Webclient Web Page:

That part is empty? What am I supposed to do? It doesn't show me what to paste into the .html or .php. I even checked on runecheck or whatever from the original poster and I still did not see what to paste into the .html/.php

Help??
