I also found another solution.

<jsp:useBean id="musteri" class="beanler.MusteriBean" scope="request" ></jsp:useBean>

I changed it to:

<jsp:useBean id="musteri" class="beanler.MusteriBean" scope="request" />

and that works..

Two points you can give a try.

[1]Initialise your class properties like

private String isim = null;
private String soyad = null;

[2][Not mandatory]implement Serializable like

public class MusteriBean implements java.io.Serializable

try to set the property by using <jsp:setProperty>

<jsp:useBean id="musteri" class="beanler.MusteriBean" scope="request" >
<jsp:setProperty name="musteri" property="isim" value=" Ferid" />
</jsp:useBean>

while displaying you can use <%=musteri.getIsim() %>
