Difference between webserver and Application server

Is there any way to stop the webserver but not the application server.
Do they run on the same port? How is that possible?

What is the difference between apps and applications?

I have an application that I've been running on my older Mac. Now that I have a new MacBook Pro, I have to reinstall new software that is compatible. When I go to the vendor website I see an application I can download or a link to the Mac App Store. Is an application different than an app? When should you download them from a vendor website and when should you go to the app store? Do apps end up in the Launchpad and an application in your Applications folder? I can't seem to find information on what is the distinction. Are they actually two different things? Any help would be appreciated.

No difference between apps and applications. If you download the app from the Apple AppsStore you have better security and a conveninet place to have all your downloads. Nothing wrong with downloading from a trusted developer though.
EDIT: Yes they will either wind up in your Download folder as a .dmg you will have to double-click on to install, or most app store apps will install to your Applications folder.

Hi, can anyone tell me what's the difference between Sun ONE Application Server6 and IAS 6.x?
Thanks a lot!

This is only the change in name from iPlanet Application Server to SunONE Application Server. Rest all is same as far as the product is concerned.

Difference between ITS and WAS server

difference between ITS and WAS server

Hello Pradeep,
The ITS is the Internet Transaction Server. WAS is Web Application Server. I'm not sure how to compare the two because the WAS from Basis 6.40 and higher includes the ITS. I think the question you wanted to ask is the difference between the Standalone ITS and the Integrated ITS???
The Standalone ITS is installed on a web server (IIS or Apache usually). It could also include another server that we call the AGate.
The Integrated ITS comes with the WAS Basis 6.40 and higher. Therefore not needing a separate web server.
There is also a note that lists some differences of the two.

BACK button difference between Weblogic and J2EE server

          Hi Everyone,
          I have a J2EE application implemented mainly with JSP and EJB, which can run on
          both J2EE and Weblogic Servers seperately. When running on either of them, the
          server acts as both a web and application server.
          It is my understanding that it first goes to the cache in the browser when you
          try to revisit the previous page (JSP files) by clicking the BACK button in the
          browser. If the page is there, it just displays that page from the cache. If not,
          it will go to the server to retrive (execute) that page.
          When I run my application over J2EE server and try to visit the previous page
          by using the BACK button in the browser, it does this way correctly. But when
          I run my
          application over Weblogic server, it always goes to the server and execute the
          JSP file again in the server, rather than simply retriving that page from the
          cache. If your JSP file is simply doing data retriving, that is fine. But if it
          is doing data inserting, it will insert your data again. This is not good.
          I know that the Weblogic server is mainly an application server. But I am not
          sure when it acts as a web server,
          why it works differently from J2EE which also can acts as both an pplication and
          a web server. Does anyone have any ideas or suggestions about this?
          Thanks a lot.
          -John


I believe that the correct behaviour is to rerun the .jsp page unless the
          user specifically sets the header to allow the browser to cache it. That
          being said... You should never make a web application that can be broken by
          the user hitting "reload" or the browser automatically retrying. An
          application like this is very fragile and will probably break in practice.
          I suggest that you either make all your pages idempotent or you keep track
          through a hidden form field a transaction id and only allow the execution of
          any particular transaction once. As far as WebLogic not being a good web
          server, I would say that with 6.1 you get most of the management advantages
          of using a separate web server and also most of the static file performance
          you will find with apache or IIS.

Diffrence b/w webserver and application server

hi all
i am very confused about actual difference between application server and web server.also tell in witch category tomcat lie. please don't confuse me give more accurate answer

I think we'll have to leave it at that, because "Application Server",
despite a bevy of definitions is still not well-defined. When someone
says they need a "Java App Server", I ask if a "Web App Server" is enough
or if they need all the EJB stuff as well.
In the end, I'd let the Tomcat website speak for itself: http://tomcat.apache.org/
<quote>
Apache Tomcat is the servlet container that is used in the official Reference Implementation for the Java Servlet and JavaServer Pages technologies.
Apache Tomcat powers numerous large-scale, mission-critical web applications across a diverse range of industries and organizations.
</quote>
Nowhere on that page is the phrase "Application Server" used (versus
the weaker web applications).

Difference between database and application

can any one tell me difference between oracle database and oracle application?
plz

BUT THE REAL PROBLEM is :-i want to connect that database..
i can't see my imported application or database..
Tell,, should i create any database or what should i
do..tell me detail step by step processFirst and foremost, you have a terminology problem. I will provide a working set of definitions. (But I fully expect to be corrected by some of the symantic specialists.)
- A database, in Oracle's terms, is a set of files.
- Inside of that database are a number of schemas, or collections of object definitions,
- Some of those objects are tables, which may contain data.
- The database is manipulated by an instance, or collection of processes and/or threads
- An application connects to the instance and requests specific manipulation.
In your case, you used the imp application, connecting to the XE database using the userid 'system' to import the schema objects from the schema 'jadi' to the schema 'yogesh'.
You could now use the application called SQLPlus to connect to the XE database - possibly using user "system" - to inspect the objects and object data imported in schema yogesh.
You might also be able to use the Application Express browser-based application to access the data in the various schemas. To do that we would need to explore other terminology such as "workspace"
I would encourage you to use the documentation at http://www.oracle.com/pls/xe102/homepage and perhaps search for the tutorial on the Products page (see the products link on the documentation page.)

Differences between Robohelp and Robohelp Server

Thanks in Advance

Hi, Rodman
You may find this article in the Adobe Developer Center
helpful as well. It refers to RoboHelp Server 6, but virtually all
information remains relevant for v7. As Rick says, "Pro" is simply
the same as WebHelp or FlashHelp, but the content is published to
the RoboHelp Server so that you can get the benefit of user
feedback reports and the other features described here:

Sorting differences between Oracle and SQL Server

Hello All,
This question is related to both Oracle and SQL Server
I have a requirement where I want to compare 2 tables line by line. One table is in Oracle and other table is in SQL Server
And suppose that both of the tables don't have a primary key. Now when I sort the records using order by clause for a column then -
Rows having null values in that column of Oracle are placed at the bottom.
Where as Rows having null values in the same column of SQL Server are placed right at the top.
How can I make either of them to behave like other.
My sole aim is to have same order of occurrence of rows in both Oracle and SQL Server tables so that I can compare them line by line.

For example :
select * from emp order by comm;
So all null value in comm column are at the end.
Now if you wish to get them on the top of select output then :
SELECT EMPNO,ENAME,JOB,MGR,HIREDATE,SAL,NVL(COMM,0) COMM,DEPTNO FROM EMP ORDER BY COMM;
Means i am using NVL (oracle function) function. If comm column is having null value it will converted to zero value at the time of exectuion of select query.
So, now comm column is having zero value in select output and SQL Server is having nulls at the top. I do'nt know who to make nulls to zero in SQL Server. So issue solved.

Bottleneck Between Oracle and Application Server

I am connecting Tomcat to Oracle thru thin JDBC driver. The link between tomcat & oracle is now found to be the bottleneck - too many JDBC calls that could be handled by the network. What are the possible solutions I can use now?
Some suggest to use Oracle Real Application Cluster (RAC) to scale the db tier. I am new to this. Would setting up RAC causes any change to my programs? Is it difficult to setup? Also, are there any other alternatives?

Web servers just handle static content, like HTML pages.
App servers have a few flavors.
A servlet/JSP engine has a Web server built into it, too. It can handle static content, like HTML pages, and also act as a container for servlets and JSPs. You can use JDBC with servlets and JSPs, of course.
A J2EE app server has a servlet/JSP engine and a Web server built into it. It can handle static content, like HTML pages and act as a container for servlets and JSPs. But it can also act as a container for EJBs - session, entity, and message EJBs. It has other services built in, like Java Messaging Service (queues), Java IDL (Corba), RMI, JNDI (naming services), XML parsers, JDBC (database access), and Java Transaction Service.
Enterprise Application Integration servers (EAI), like WebMethods, using XML messaging to tie multiple J2EE app servers together.

Could any one tell me what is the difference between swfloader and module loader?

Hi All,
                      Could any one tell me what is the difference between SWFLoader and Module Loader in Flex3 in detail?

Hi,
ModuleLoader is a kind of strange API that is really just intended to look like SwfLoader for modules that contain a single visual component, and hides most of the module loading infrastructure, which is all about class factories.
What I mean by "only loaded once" is that if you have several places in the code that call the ModuleManager.getModule("url").load() call, it will only ever get loaded over the wire and interpreted once, subsequent "loads" will just re-dispatch pseudo-load events to the new client. In other words, the class factory is a singleton for a given url. Unloading is a totally different story. As you note, not everything is truly unloadable, because there may be lots of references to stuff in
the module that will keep it alive and un-GC'ed.
I suggest playing with the low-level API so that you understand the backing implementation, and this should help you understand the limits of ModuleLoader.
The main difference between modules and applications is that modules have lower overhead, and they only ever get loaded once, no matter how many times you load them. If you're using the ModuleLoader API, keep in mind that you're losing about half the functionality of the module system. I will assume that you are, because otherwise it would be obvious where to expose methods. You might want to play around with the lower level ModuleManager API just to get a hang of what's going on - ModuleLoader is a pretty thin veneer over the lower API.
                Basically, what you want to do is to have your module implement an interface, say IModuleWhatever.
Also try and refer to this link which was previously discussed in this forum..

Hi there
The difference I know is the application servers provides the containers for the applications to run which is not provided by the web servers.
For example the containers can be an EJB container or JSP container etc
