    Default Need help figuring out what needs fixing please!

    I get this error code when I run the project.

    java.lang.ExceptionInInitializerError
    Caused by: java.lang.RuntimeException: Uncompilable source code - cannot find symbol

    Can you copy the full text of the compiler's error message and paste it here?

    What you've posted looks like it is from trying to run a program with a compiler error.

    Looks like the statement on line 103 is missing the first part of a for statement. Try adding: for(
    for(int i =....

    C:\Users\Stino\Desktop\Reflection\src\Reflection.j ava:15: error: cannot find symbol
    private static client c = null;
    symbol: class client

    The compiler can not find a definition for the client class. Where is the definition for that class?

    The same for the other cannot find symbol errors

    I'm not sure, I attached the source code at the top in the form of .rar

    --- Update ---

    "The client your trying to use is probably obfuscated (or they changed their client.class name) which means all of the .class files are completely different." another person from a different site just told me this.

    please post a link to the other site.

    Please post your updated code here wrapped with code tags:

    [code]
    **YOUR CODE GOES HERE**
    [/code]

    to get highlighting and preserve formatting.

    I wasn't actually told by anyone i just had read it, basically I am trying to figure out how to de-obfuscate a client for a runescape private server, I tried putting the source code of the client (its a .jar) into a reflection client, but when I compile it runs those errors, so now im trying to figure out how to get the reflection client to accept the .jar

    }

    This is the .java that is giving me all the problems.

    To fix the cannot find symbol errors, you need to have the definitions for the missing classes on the classpath for the javac command.
    If you have a jar file with the classes' definitions you can use this command to compile the Reflection class:
    javac -cp .;<THEJARFILENAME>.jar Reflection.java

    Same problem. You need to get a definition for the missing class.

    If it's obfuscated, you could decompile it, to get a list of class objects and method signatures. This would reduce your search to determine which classes you are after.

    Also just extracting the jar with a zip archives would allow you to see the basics of what is available within the bundle.
