Hello
I have java bean where in there is one property as
below
private java.lang.String P813NAME ;
public void setP813NAME (java.lang.String P813NAME )
{
this.P813NAME = P813NAME;
}
public java.lang.String getP813NAME ()
{
return this.P813NAME ;
}
is this valid or not?
if not why not and where i can find specification for
java bean

The JavaBeans Specification can be found here:
http://java.sun.com/products/javabeans/reference/api/index.html
The spec deals with uppercase property names by looking at the first two
characters, and if they are uppercase, not decapitalizing. Since your
second character is a number, my guess is that it will think the property
name is p813NAME, not what you want.
If you can possibly rename this property, do it... your life will be much
easier. And if you don't get a good answer here, try commons-user and put
[beanutils] in the subject line.

You must be scott ambler fan :-)
Or maybe not, he suggests words like a, an, some
public void setValue(int aValue){
value = aValue;
}
In his coding conventions...

P.S. don't blame anyone for using this.x = x too fast, it's often generated
by ides, even eclipse did it in one of the versions.

Since this thread was marked as OT, I figured I'd contribute an OT reply :)
It is worth noting that the syntax...
this.someProperty = property;
...is usually flagged by static code analysis tools because the incoming
parameter shadows that of the class. True, using "this" disambiguates (is
that a word?!?) the reference and no harm is done. I myself used to use
that syntax all the time.
However, I've gotten into the habit of doing...
public void setSomeProperty(String inSomeProperty) {
someProperty = inSomeProperty;
}
...if for no other reason than to avoid the extra errors emitted by
CheckStyle and the like.

>From the javabean spec this is acceptable. However, it is not good coding
standards to have a property in all upper case. The java standard naming
convention has constance as all upper case, properties as camel case.
Struts would have a problem with this because it is looking for the first
letter of the property to be lowercase.
if this is a procedure name it would be better to have the parameter as
either p813name or procP813NAME.
