I want to create a connection to the internet. The connection can be established within a cooperate firewall. How do I know on runtime if a firewall / proxyserver is used?

Johannes
I must have an environment entry that I can change on runtime. It must work for Tomcat 5.0 and 5.5. I thought a solution was to add a META-INF/context.xml to the war file. It works for 5.5 but it doesn't work for 5.0. Does someone know an other (better) solution?

Does someone know how I can create a connection to a remote host via a proxy? I use in my applet Sockets. The solution must work for http and https. I know that if I use URLConnection the proxy settings are automatically read from the browser settings. This is not the case by Sockets. Do I read first the System properties and how do I know if authentification is needed? Is this also part of one of the properties?

Hi,

Is it possible if you have a https connection with a server to see the encrypted message from the server or the encrypted message to the server?

I don't think that getParameterInfo() will do the job. I want to retrieve the parameters dynamicly. The applet doesn't know anything about the parameters not even the parameterNames. I want some method like getParameterNames().

I want to retrieve the parameter names in the applet. Is there some way to do this?

Thanks! But I don't want to self sign the applet because of the warning. I'm thinking about selling the applet and a self signed applet is therefore not an option.

I have created an applet and now I want to sign the applet. Therefore I need a "code signing digital id" from a CA. The digital id's from Thawte and Verisign are very expensive ($199 and $399). Does someone know a CA that issue cheaper "code signing digital id's"?

I think this is a question for the SCBCD forum.

It's not true. The client connects to a stub. The stub not part of the ejb-jar. This jar is a file that the Bean Provider provides. On deploy-time the stub for the client is created. This is a task for the deployer.
How can I retrieve the whole content of a the response of a HTTPUrlConnection (including headers and body)? E.g.

Statuscode: 200
Content-length: 1582
Content-type: tex/html

<html>
<body>
...
</body>

Dibbo,

Java is used mostly in internet and intranet environments. This means that you have to code servlets and jsp's and most likely ejb's. Therefore SCWCD and SCBCD are important.

I'm working in a bank in the Netherlands. We hardly use web services. I believe that a lot organisations are sceptical about web services in internet environments. The reason for this is, is that the security of web services are still immature.

Therefore, if you are not yet a java developer for profession, I would recommend SCEA. Or you can study an application server, e.g. WebSphere.
I think you can do the exam. Most topics has nothing to do with Servlets or EJB's.

You see not so many posts on this forum because SCDJWS is a relative new certification. I think SCWCD and SCBCD has more sense for a developer. If you want to become a developer for profession you can do better SCEA than SCDJWS. With SCEA you learn how to design an enterprise application.
I have had no questions about level 0 or level 1 api. But this doesn't mean that no questions are being asked about the levels.

The exam objective is:
Describe the function of JAXR in Web service architectural model, the two basic levels of business registry functionality supported by JAXR, and the function of the basic JAXR business objects and how they map to the UDDI data structures.

With other words you have to know the two levels!

Success with your preparation.
I have had no questions on my exam regarding the level 0 and 1 api's of JAXR.
