How To Unblock Websense In School

An internal DURING error occurred: "JSP Content Validator".

In the office where I work we use MyEclipse as IDE and constantly when editing XML files or JSP in some projects, using MyEclipse 6.0.1 GA, has typically launches a pop every time we try to keep this type of files with the following errors:

DURING An internal error occurred: "JSP Content Validator".

org / eclipse / wst / sse / ui / internal / Reconcile / validator / ValidationHelper

DURING An internal error occurred: "JSP Semantics Validator (JSF)."

org / eclipse / wst / sse / ui / internal / Reconcile / validator / ValidationHelper

DURING An internal error occurred: "JSP Syntax Validator".

org / eclipse / wst / sse / ui / internal / Reconcile / validator / ValidationHelper

And as I ran out of patience, I was investigating and apparently many people have the same problem, but found a quick fix but nothing attractive, which is to disable the validation of JSP and JSF.

To do this we must open the preferences window is
MyEclipse menu -> Preferences
... and clear the check boxes for
JSF Application Configuration

Validator,

JSP Content Validator
,

JSP Semantics Validator
,

JSP Syntax Validator

With this we will provisionally
fixed the error of the validations
showing those annoying pop-ups whenever we want to save a file or
JSP XML

Starting with Java (1)

As promised, and not reinvent the wheel, I decided that instead of recording a video tutorial and bore you with my voice, give them better access to some videos that others have done a very professional manner .

1. The first videos are ones that I found while searching for how to help some friends to whom I gave tutorials. They are videos that start from the basics of Java through the IDE, concepts, branching, iteration, vectors and some examples. http://www.videoaprendizaje.com/index.php?topic=536.0 2. The following are a series of very professional videos in order to be an SCJP certification course for Engineer Julio César Fuentes Ochoa licecia released under Creative Commons. You can download two versions of the same author, in two different places.

Anyway, I hope you enjoy these video tutorials and will be of great benefit. Keep visiting us, we will promptly videos with more specific purposes. If you have requests or follow POSE send via Twitter .

Cubefield Level Three

Is PHP or Java?

Sometimes some friends ask me what programming language should learn, and I say - the one you want. But honestly is a bit more complicated, because they should first ask "Well, what do you want? -

But maybe the question should be redefined and now

explain why ... Because I remember that we left the class task of comparing the technologies PHP, Java and. NET. But I think both technologies, PHP and Java, are not comparable, and not to say that PHP does not come on the heels of Java, do not misunderstand me.

should keep in mind what is PHP. PHP is a Web programming technology, for it was created. But Java is a technology platform with which they can make web applications, desktop, mobile, and so on. Perhaps the comparison should be done is "What do I need for what I do, PHP or JSP / Servlets?." Because JSP and Servlets are a set of Java APIs that allow you to program Web applications. In addition to these, Java has dozens of other definitions that can be made many things.

So if you ask me - What programming language should learn? - I might ask - What you need to do - it is with JSP and Servlets can do what you do with PHP and more.

Now, do not want to fall in that you can program in Java just as you would with PHP, because we must also recognize that there is a learning curve higher in Java than in PHP language. Not to mention that when one wants to make things more complex and robust must learn to use a framework to accomplish their work.

Outside of that, so I always recommend is learning Java, since programmers Java has a great demand in Mexico and many countries and are very well paid. There are a lot of free documentation and professionals willing to help.

So join us and follow us constantly to be learning Java. Soon we will start with the videos ...

How I can learn Java? Software Guru

The http://www.swcoders.com blog a while ago I published a post where I explain five tips on how to learn to program in Java, and any programming language works alike. As this is a copy & paste the same:

On several occasions my friends have asked me about how they could start learning to program in Java. For what I have always answered is " reading and doing." When I learned to program in Java was because some friends told me the same thing, but where does it read?, What these friends said, and I answer now to make me the question is that "Google has is that learning to program in any language

and to be fond of programming, the person must be an outstanding researcher. And if you've got here is because you are looking to learn, and we are here to facilitate your learning.

Reading. There are many tutorials scattered all over the Web, it's just a matter of knowing look. Well if you put "Java tutorial OR manual" in any search engine you'll get hundreds of tutorials of Java. Only thing that you're a weekend with coffee and fried in front of the computer. If you are more traditional, there are hundreds of books for very cheap mercadolibre.com, although there are also electronically. A place that is always going to help you www.g2p.org hacks google to search the index server searching for what you want.

Using
. Many tutorials are basic practical examples with which you can start playing. In these tutorials will explain how to configure your Windows or Linux environment to program in Java.

not afraid to English. A fear factor that I see often in a few friends who want to learn to program is that many books and tutorials to get are in English. But to be fond of computing, you learn not to fear the language, and I do not mean you are multilingual, but at least you will be learning to read English while learning to program. But fear not, there are now lots of information and tutorials in English are very professional and easy with which you can learn. Forums

. You can also subscribe to forums where you can ask questions about your questions and tell you more of a Java developer will be willing and have the answer you want. Some are: FIT Forums
, javahispano.org
, programacion.com
,

programacionweb.net . Podcasts

. Podcasts are a means by which you can stay updated on the latest news and new tools on Java. This will help you open your mind to many things that exist in the Java world you may not know. The podcast I hear most frequently is that of
javahispano.org

, and the

javaposse.com in English.

The original note this here.

I invite you to take a tour by

SWCODERS and view the material and tutorials out there.
