It may be because you are trying to assign an object to a String, instead of assigning that String to the object. what happens if you had

String NAME;
 request.getParameter("NAME") = NAME;

Don't even know if that makes sense my friend! :)

No, the original syntax was correct. String name=request.getParameter("NAME") should work given the following:
1. "request" is a valid variable.
2. The class that "request" is an instance of has a getParameter method which a) takes a String argument and b) returns a String.

Check that you've satisfied the above.

Do you know any examples of what I said where I would be correct? Any scenarios you can think of off your head? I remember a teacher telling me i needed to switch the expressions on each side to fix a problem I had before.

C:\Documents and Settings\ASPHire\My Documents\NetBeansProjects\schedular\src\register1.java:147: cannot find symbol
symbol : variable request
location: class register1
String COMPANY= request.getParameter("COMPANY");
i got that in netbeans output console

C:\Documents and Settings\ASPHire\My Documents\NetBeansProjects\schedular\src\register1.java:147: cannot find symbol
symbol : variable request
location: class register1
String COMPANY= request.getParameter("COMPANY");
i got that in netbeans output console

I have never seen this Object class being used before but

//you have
private Object request;
//If it is like creating an instance any other object I would write it as:
private Object request = new Object();

Maybe this is why it cannot find request, because it wasn't initialized?

Not sure quite what you're asking, but I would assume you're posting stuff that you think will resolve the problem, and is therefore correct...

As to switching the sides, that may sometimes work, but it's not very good practice to just randomly switch sides or add code segments. You should understand why something works or not.

In this specific case, the variable on the left is assigned a value. The OP was getting a value from a method, therefore it follows that the returned value should be assigned to a variable. It wouldn't make sense to assign a method a String.

acctually i m creating desktop application so i m asking that "request .get parameter" is worked here or not because thats used in JSP programming.

As akill10 mentioned above, you have not initialized the request variable. You have only declared it.

You don't actually. 'request' doesn't really apply in your desktop application. You need to get the text from your text fields.

like it.... 1st text field is name of "T1" so i just have to put...
String MAME= T1.getText();
