Hello Everyone,

I have cleared SCWCD 1.4 with 85% 59 out of 69. I thank Javaranch for providing such a informative forum which helped me pass the certification.
I would also like to thank kathy sierra and bert bates for providing such a informative book.
Thanks also to Whizlab the Exam Simulator is really a great help for preparing.

I startet on 09/19/2007 with reading HFSJ
and from 09/24/2007 i tried all available Exam Simulator most time Whizlab
and Marcus Green's but i think (sorry Marcus) your Simulator is a little bit
to easy. Thanks to Peabody's Pattern Description they helped me really (83%).
The Exam-Simular here on JavaRanch is also fine.

i learned every day between 8 and 10 hours.

Thanks to all

Hello,
i can't set the values for the ListBox
here is my coding:

public List getDrinks() {
drinks = new ArrayList();
drinks.add(new SelectItem(new Integer(1),"Kaffee"));
drinks.add(new SelectItem(new Integer(2),"Tee",""));
drinks.add(new SelectItem(new Integer(3),"Milch",""));
drinks.add(new SelectItem(new Integer(4),"Kakao",""));
return drinks;
}
and this is the JSF definition
<h:selectOneListbox styleClass="selectOneListbox" id="drink" size = "1" value="#{pc_Welcome.mo_User.drink}">
<f:selectItems value="#{selectitems.pc_Welcome.mo_User.drinks.drinks.toArray}" />
</h:selectOneListbox>

and the Output of the Box looks:

javax.faces.model.SelectItem@xxxxxxxx
javax.faces.model.SelectItem@xxxxxxxx
javax.faces.model.SelectItem@xxxxxxxx
javax.faces.model.SelectItem@xxxxxxxx
xxxxxxx is the Reference to an Object (i think)

can anybody help me and tell me what i am doing wrong ???

Hello,

has anybody already passed the IBM Certification 731 DB2 9 DBA ???
but which of the two IBM 257 or SUN SCWCD is better for job ?
Hello,

Today i took IBM 285 exam with 88 % and IBM 730 DB2 V9 Fundamentals with 70 % 45 out of 64. The 730 is really simple but it is requested for DB2 V9 DBA .

For 285 it was a great help the http://java.boot.by/icad-guide/ from Mikalai Zaikin and the Q/A from Itexamworld.com

Now my Question how much time do i need for preparing on SCWCD or is it better
to take the IBM Test 287 IBM Certified Enterprise Developer - WebSphere Studio, V5.0

Martin

Hello,
