Congrats!!!

Tell me something, how was the 639 exam? what did you use to study?


Regards

I always worked using PC, and now I'm planning to buy my first mac, a Macbook.
But before that I have a newbie question... I see in this forum that is possible to work in Mac OS with java SDK and eclipse... but I'd like to check if do you guys think is possible to work with most Application Server, for example WebLogic, websphere and jboss? Does anyone work with this AS in Mac OS?
Thanks

I saw that in the information page of some IBM's exam there's a Sample/assessment test for $10, is it obrigatory to do before schedule the exam in a Prometric test site?

Does anybody did this sample/assessment for $10?

here is one of this kind of information: http://www-03.ibm.com/certify/tests/sam285.shtml

thanks

I dont think that its only for partners...

I think that it's open... the only problem is that the last exam is about Rational Rose... not only OOAD Concepts.

Thanks Nicholas, I think that the upgrade exam is the better choise because its cost less than the normal exam, and if I pass I will have the same certificate.

So... in the upgrade exam I will only have questions about Java 5?


Thanks

I'm a SCJP for Java 1.4, and I'm planning to do the SCJP 5.0 exam.

Which choise is better, do the SCJP 5.0 Exam or the Upgrade Exam?
What's the diference?


Thanks

I see what I was doing wrong.

I update my web.xml to 1.4 and now everything is woking

<web-app
xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" version="2.4">

Thanks all

I have a code like this in my JSP:

<c:if test="${userVar eq "teste"}"> Yes its right </c:if>

if I use double quote like "teste" inside a jstl it doesnt function.
But if I use ${userVar eq "teste"} out of a jstl if tag, theres no problem.

why its happen?

thanks

Yes, I did it and nothing happened

The name and the directory is:

<tomcat_dir>\webapps\SCWCDStudy\testScripting.jsp

I'm trying to make invalid for a JSP to have scriptin elements, I put in the DD:

<jsp-config>
<jsp-property-group>
<url-pattern>*.jsp</url-pattern>
<scripting-invalid>true</scripting-invalid>
</jsp-property-group>
</jsp-config>


and in the jsp:

Testing if the scripting is disabled:
<%
out.println("scripting enable");
%>


But this JSP still work, does anybody know what I'm doing wrong?

I have a little doubt about Tomcat Connection Pool using jndi/dbcp:

When I do something like it:
public void init() { try{ Context ctx = new InitialContext(); if(ctx == null ) throw new Exception("Boom - No Context"); DataSource ds = (DataSource)ctx.lookup( "java:comp/env/jdbc/TestDB"); if (ds != null) { Connection conn = ds.getConnection(); if(conn != null) { foo = "Got Connection "+conn.toString(); Statement stmt = conn.createStatement(); ResultSet rst = stmt.executeQuery( "select id, foo, bar from testdata"); if(rst.next()) { foo=rst.getString(2); bar=rst.getInt(3); } conn.close(); // here is my problem } } }catch(Exception e) { e.printStackTrace(); } }

why I always need to close the current Connection?
I was think that if I do it the connection will be closed, but I realize that it returns to the pool, right?
How does it function? I call a method to close a connection and instead close it, it return to the pool.

Thanks

Is there any way to make paging using Velocity?


thanks

I don't know if it's a doubt about OO or J2SE, but in this case when you construct an object of "B", the compiler will invoke the superclass constructor, then will the superclass not be alocated in the memory? but their static content will be initialized?

In the case that I asked about servlet hierarchy, in the superclass MainServlet I override the init method. For each children of MainServlet the init method will be invoked?


thanks
