2.1 – Step 1 – Signlink.java
Open up Signlink.java and search for findcachedir(). In that method you will see something like this:
| s = “”; s1 = “./cache/”; |
highlight those 2 lines and replace it with the following:
| s = “C:/.yourclientname_file_store_32/”; s1 = “”; |
replace yourclientname with the name of your client – no spaces. 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 it 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
{
if(aClass14Array970[0] != null)
{
aClass14Array970[0].method234(abyte0.length, abyte0, (byte)2, i);
}
}
catch(Exception exception3)
{
aClass14Array970[0] = null;
}
}
catch(IOException ioexception)
{
if(s2.equals("Unknown error"))
{
s2 = "Connection error";
}
abyte0 = null;
}
catch(NullPointerException nullpointerexception)
{
s2 = "Null error";
abyte0 = null;
if(!signlink.reporterror)
{
return null;
}
}
catch(ArrayIndexOutOfBoundsException arrayindexoutofboundsexception)
{
s2 = "Bounds error";
abyte0 = null;
if(!signlink.reporterror)
{
return null;
}
}
catch(Exception exception1)
{
s2 = "Unexpected error";
abyte0 = null;
if(!signlink.reporterror)
{
return null;
}
}
if(abyte0 == null)
{
for(int k1 = l; k1 > 0; k1--)
{
if(i1 >= 3)
{
method13(k, (byte)4, "Game updated - please reload page");
k1 = 10;
} else
{
method13(k, (byte)4, (new StringBuilder()).append(s2).append(" - Retrying in ").append(k1).toString());
}
try
{
Thread.sleep(1000L);
}
catch(Exception exception2) { }
}
l *= 2;
if(l > 60)
{
l = 60;
}
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 webclient will not work.
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();
Out.close();
}
public void unZipFile()
{
try
{
ZipFile ZipFile = new ZipFile(signlink.findcachedir()+dir+name);
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)
{
e.printStackTrace();
}
}
public void deleteFile()
{
try
{
File file = new File(signlink.findcachedir()+dir+name);
file.delete();
}
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. I don’t know why. =\
Open up Class30_Sub2_Sub1_Sub1.java and replace all:
| ./Sprites/ |
with this
| C:/.yourclientname_file_store_32/Sprites/ |
Like this:
Do the same for the background
Once you have changed the location your client reads the sprites from, save the file and close it.
————————————————————————————————————–
2.4 – Jarring and Signing
Before we start make sure you have downloaded the jar maker(located above).
Note: When you jar your client the cache and sprites folder can not be in the client folder. Move or delete them.
If you have already downloaded the jar maker then run the jar maker and watch the following video.
Jarring and signing video: http://www.youtube.com/watch?v=9obXgxm_9qY&fmt=18
Once you have jarred and signed the client, Put the cache files(Everything inside the cache folder) and sprite “folder” in a zip file.
To understand what I mean watch this video:
http://www.youtube.com/watch?v=KUPvCEObZuk
————————————————————————————————————–
2.5 – Webclient Web Page
Create a new html or php page with the following (This is an example of how it should be):
| <HTML> <HEAD> <TITLE>Your Webclient</TITLE> <META HTTP-EQUIV=”PRAGMA” CONTENT=”NO-CACHE”> </HEAD> <BODY> <applet name=”yourclientname” width=”765″ height=”503″ archive=”client.jar” code=”client.class”> </BODY> |
Replace yourclientname with the name of your client.

Section 3 – Extra
3.1 – Frequently Asked Questions
Question: What’s a good free file host for my cache.zip?
Answer: You can use any host that allows direct linking. I personally use this site:
http://www.fileden.com/
Question: Ric, 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 get a blank page with a red X on it. What do I do?
Answer: Right click and press Java Console and read the error.
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.
Question: I get the 1,2,3,4,5 error. What do I do?
Answer: Something is missing, corrupted or done wrong.
Question: I get a java heap space error, What do I do?
Answer: Make sure you have <param name=”java_arguments” value=”-Xmx1024m”> in your applet code.
