Finder no such method exception

[simteq]

I am running 2.4.1a
I have defined a finder method in jaws.xml (deployed as part of my bean jar file) ie:

findByUsername
username = {0}

<read-ahead>true</read-ahead>

where username is mapped to a field name ie:
<cmp-field>
<field-name>username</field-name>
<column-name>USERNAME</column-name>
<jdbc-type>VARCHAR</jdbc-type>
<sql-type>VARCHAR(12)</sql-type>
</cmp-field>
however when I try to call it in the client ie:
IndividualHome indHome = (IndividualHome)ctx.lookup("TMS/Individual");
Individual ind = indHome.findByUsername( username.toUpperCase() );

it gives me an exception for NoSuchMethodError.

Any help would be appreciated.

Have you define the method in the Home interfaces ?

[swaminathan17]

also try giving the actual column names
in the USERNAME = {0} .

The coding in IndividualHome is:
public Individual findByUsername( String username )
throws FinderException, RemoteException;

Thanks for your help guys, the problem was to do with the column name being defined in the finder in lowercase but in uppercase in the cmp-field definitions.
