Why JSP and XML?

Swift&Smart · 06-14-2003, 12:16 AM

Hello,everyone

.I am learning PHP right now for quite several months.Meanwhile,I am wondering why some of the firms (Big enterprise) use JSP as their server-side language.Why don't they use PHP?Not secure?Not popular?Not scalable?Or what?I don't know.Do you have any ideas?And why do they use XML? XML is pretty new to me and not very popular.What's the advantages of XML?

I would be appreciative if you could respond to my questions.

Everyone has their preferences.

XML is a nice way to store data of many kinds.

Are you kidding?

XML is very popular and everything is using XML today. It can be used for platform independent data transfer, data storage, and configuration, etc. For example, web services (both ".Net" and "J2EE") are using "XML" to transfer the data platform-independently. And development tools like "Ant" (java build tool) , "Ghost installer" (windows installer making tool), and so many other tools are using XML to configure. And WML (formatting language for WAP) is based on XML. And some databases use XML to store data. And even XML based programming language is going to be developed in future.

Here are some advantages of java over php.

- java supports multithreading.
- java is fully Object Oriented while PHP has partially implemented OO paradigm.
- You can create almost everything with Java, from style-sheet application, games, client/server applications, etc. but PHP is quite limited. Eg: you cannot create a server application using PHP without the help of web server.

This article is about comparing Java and PHP. It explains why PHP is suitable for small web applications while Java is suitable for big applications.

I'm pretty sure that JSP uses Javascript rather than Java applets... if this is the case then a lot of what you said is moot.

I don't know what u mean. JSP is serverside programming and JavaScript and Java applet are client side programming. It has nothing to do with each other. Ofcourse you can insert both JavaScript and Applet inside JSP code.
Please!
A lot of people make this mistake.
Javascript and Java is TOTALLY different technologies. It's just their names are similier. JavaScript is NOT from Sun. It's from Netscape. JavaScritp has nothing to do with Java.

I'd have to agree with moe. JSP doesn't depend on Javascript or Java applets. It's serverside, similar to PHP. This comparison is pretty good.

We use JSP at work as it is based on an actual programming language - this means our business logic can be written in a strong OOP language with good XML suppot and many 3rd party libraries, with the presentational code being done using JSP.

Well in fact what I do is use JSP to write out XML, then use XSLT to do the presentation. But I'm just perverse

I read this last night. I'm not a big fan of XML, I think it's too over-the-top and just another way to do something, not THE way.
Here is an article that (at last) didn't just blabber about how good it is, but actually looked at XML a bit more critically.

Good article. I would question the whole concept of web services and middleware (in the way that the vendors are building it up), but if you have all these people running out to spend their money, while you save your money and work with GPL and LGPL, than let them use XML!

I have read all you guys messages and one of the introduction chapter of J2EE. I can conclude that J2EE seems like having many components and very complicated,but it turns out that the functions are pretty similar with PHP.

I don't know what Java Servlet,JavaBeans actually mean before.However,I realized that they are very simple functions in PHP.Like others,one of the weaknesses of PHP is OOP(Object Oriented Programming) architecture.They don't have "PRIVATE" or "PUBLIC" mindset.As far as I know,OOP will be improved in PHP5.However,I actually don't know why "BIG ENTERPRISE" doesn't give PHP a shot.I have seen many "BIG ENTERPRISE" using JSP.And I plan to learn it anyway while they use it.

By the way,I have a quesiton on GtkUser,is it costs much money to use XML?And XML seems like progressing very very slowly....
