Thanks so much for taking the time to make such an informative reply (even though it made my head hurt ). I really have no preference as to what type of Java developer I want to be just any type at this point. There is so much to learn and I'm just really overwhelmed. I started reading "Effective Java" and "Head First Design Patterns" so that I can at least feel a little more confident with the language basics. Does this seem like a good strategy?

Hello,

I have passed the SCJP 5 and SCWCD 5 exams and am now confused as to how to proceed. I'd like to become a better developer and I feel that studying and passing the SCJP and SCWCD isn't enough, I still don't feel as though I adequately know these technologies enough to get hired as a Java developer. I guess what I'm asking is what books would you suggest I read in order to sharpen up my skills. I feel that I should focus on improving my SCJP and SCWCD skills rather than continue to just rack up certificates. I'd really prefer books that have code examples rather than just theory....I'm really confused at this point, I'm 1/2 way into a Java Web Services book but I sort of feel as though I have no businesses reading this book when I'm so new to Java in general...or maybe I should be learning a framework and if so which one?

If it helps, I have 7 years of QA experience where I did automation programming but have never been employed as a programmer. I took a few semesters of Java programming and then last year studied at obtained the two Java certs previously mentioned. I have also been a stay at home mom for the last 2 years and want to sharpen up my skills before I try and return to the job market in another year when my toddler turns 3.

Thanks so much your help is very very much appreciated!

Thanks so much for the replies. I got sick of trying to figure it out and instead went back to tcpmon - Thanks for the wsmonitor suggestion, I've never heard of it I'll have to check it out.

Hello, I'm having a hard time figuring out how to trace soap messages. I can use tcpmon but would really like to use Metro's jaxws-rt.jar version since with the Metro version I don't have to alter my code.

Here's how to do it accoring to the book Java Web Services Up and Running:

In the book Java Web Services Up and Running using the Metro tracer sounds so easy:
"The metro release has utility classes for tracking HTTP and SOAP traffic. This approach does not require any change to the client or to the sercie code; however, an additional package must be put on the classpath and a system property must be set either at command line or in code. The requierd package is in teh file jaxws_ri/jaxws-rt.jar. Assumming that the environment variable metro_home points to the jaxws-ri directory, here is the command that tracks HTTP and SOAP traffic between the timeclient, which connects to the service on port 9876, and the timeserver service.
%java -cp ".":$metro_home/lib/jaxws-rt.jar \
-Dcom.sun.xml.ws.transport.http.client.HttpTransportPipe.dump=true \
ch01.ts.TimeClient.

The resulting dump shows all of hte soap traffic but not all of the http headers. Message trackign also can be done on teh service side.



Here's what I'm doing:
I'm not using any sort of development tool such as Net Beans.
1. I start my publisher service to make my wsdl available:
import javax.xml.ws.Endpoint;
class RabbitCounterPublisher{
public static void main(String[] args) {
int port = 8888;
String url = "http://localhost:"; + port + "/rabbitCounter";
System.out.println("publishing rabbit counter on port: " + port);
Endpoint.publish(url, new RabbitCounter());
}
}
2. From Windows xp command line I execute my client as follows:
C:\JavaProjects\RabbitCounter\source>java -Dcom.sun.xml.ws.transport.http.client.HttpTransportPipe.dump=true FibClient

RESULT:
My client runs successfully and is able to make calls on my Web Service.

QUESTION:
I thought that setting the property "-Dcom.sun.xml.ws.transport.http.client.HttpTransportPipe.dump=true " would make my soap messages dump out to a file however I'm not sure where this file is. Also, I do have an environment variable METRO_HOME set and I have jaxws-rt.jar in my classpath. Basically, I'm just confused as to how to get this thing to work. If anyone has experience with this I would really appreciate the help. Thanks!

Hi himanshu kesarwani,

I too was really new to Servlet and JSP. As mentioned, the Head First Java Servlet and JSP book is really great and a must read. If you need a very very basic beginner book read Murach's Java Servlets and JSP, 2nd edition. It has very easy step by step instructions but it is very light on content and will not suffice as the sole study aid for the SCWCD exam. I read the Murach book first and then the HFJS book and it really helped me understand the concepts.

Thanks everyone for the replies! I'm trying to change fields from QA to dev because I moved to a city with very unfulfilling QA jobs (I was in Silicon Valley for 6 years where the job opportunities were creative and fun), the jobs have been more like tester positions that any high school kid could do, so basically I went from learning and participating in hot new technologies.. to point and click testing. Any advice on what other technologies or Java certs I should get in order to become a website developer - book advice would be great. Thanks again.

Hello,

I was wondering if people felt that these Sun Certifications actually qualify you for a programming job. Even though I have received my SCJP (and except to get my SCWCD in a couple of weeks) I do not in any way feel qualified to have a programming job. I feel like I can answer the questions fine during an interview but have no real world experience. I don't really feel like studying for the certificates has given me enough confidence or knowledge to be a productive programmer. Do others feel this way? Are companies willing to work with new programmers with certifications but without real world experience?

I have a bachelor's in MIS and have been doing QA work for about 8 years, so I'm not new to IT. I had a baby 2 years ago and quit my job to raise him until he's ready for daycare which I think may be soon. About a year ago really needed something to keep my mind busy and started worrying about reentering the workforce with such a lapse in my resume, so I decided to learn Java. I plan on getting the EJB certificate after getting the SCWCD and then perhaps getting the Web Services cert since I do have some experience with Web Services already. With my QA background combined with these certs is it really possible for me to get a programming job? Thanks so much!

Thanks so much, that makes sense.

Why does the code below cause the following error to be repeated when ran:

at Testing.<init><Testing.java:5>

class Testing {
Testing t = new Testing();

public static void main(String [] args) {
Testing t2 = new Testing();
}
}

Thanks so much for your help!
