Why PHP is better than JSP,Servlet(Java Web Apps) ?

Well, my heart says JSP, Servlets are better but rent a coder and job market, demand-supply seems to be saying a different story... ? Why we should not learn PHP then ?

You can develop web sites in PHP in two shakes of a lambs tail. But they aren't maintainable as they would be in .NET or J2EE and again the performance (which dicates what you can do as well as scalability) is between a scripted language with buggy runtime and a compiled language with an optimized runtime so you tell me. Yes, but rather like Spinoza's argument for the existence of God, an application that has existence is more perfect than one which exists only in the conception. Even if the conceptual one is faster.
I don't denigrate languages like PHP that help novices get stuff done.
To address the OP's complaint: If one language was objectively "best" then we would only need one language. In practice they all have strengths. The more you learn the more you'll know which to use for the task at hand. That said, to learn any language (even PHP) in profound depth will take the best part of ten years and maybe longer. Sometimes expediency leads us to use the language we understand better to solve a problem for which it is not ideally suited.Eloquent - well said.
Bonus points for that Spinoza reference.

Why Annyconecct is better than vpn client ?

why anyconnect is better than cisco vpn client ?
what is its advangatges ?
i think that both are remoteaccess vpn .
why its better ?

The other thing is that, Cisco does not support traditional VPN on Windows 8.X. I have run in to lots of issues trying to install Cisco VPN client on Windows 8.x clients.. it sometimes work and sometimes it needs registry hacks etc.. really painful setup for the network engineer. So Anyconnect is preffered.
Also, since SSL uses port 443/SSL by default, it does not need any ALG (Application Layer Gateway) functionality in remote end user's routers to operate, and will simply work with normal PAT which is always on.. with traditional IPSec VPN, since it uses ESP, you need to have AGL turned on on the user's GW router (this is normally called IPSec VPN pass through mode) and this sometimes doesn't work the way you want specially on the older residential routers. When this happens you really don't have any other option for those users.. and your only response would be "Sorry your router does not support this kind of VPN or your router does something strange with the VPN so Please upgrade your router" which is something the normal residential user don't want to hear.. and something you want to tell them..
So SSL VPN is the way to go..
please rate helpful posts :)

Why VPC is better than VSS?

virtual port channel
why VPC is better than VSS?
any thing about VSS is better than VPC? if so, when to use VSS?

for example, if have N7K, use VPC.
Well yes because you can't use VSS with Nexus.
how to think in terms of design?
Don't really know what you are asking.
As for the arp question it seems completely unrelated to what you originally asked.
Try and focus on one question at a time and try and be clearer in what you are asking.

Why is mac better than pc?

Hi guys.
I'm doing a speech on why macs are better than pcs and have to come up with two college-level citations to support the point. Would you guys be able to help me with that? All I need is some data that can help me support the point.
Thank you !

Funny ... as my wife worked on her masters a couple years ago, Cal State Fullerton would not allow ANY citations from the Internet.
But here's some background info for you ...
http://www.apple.com/mac/
You say you're a new MacBook Pro user ... What do YOU think about your new Mac?
I was a Windows devotee for about 20 years. Until my wife brought home a co-worker's 17" MBP for me to play with. And I turned it on and played with it. And played with it. Realized it was about 3am the next morning - it was so enjoyably engrossing. I ordered my own that very day, and haven't looked back for a moment. Like excellent shoes that you can FEEL make a difference in your posture and spinal health, switching to a Mac was darned near a religious experience for me.
And I am not alone ... (grin)
Good luck with your research.

Why A is better than B/G for Voice over WLAN

Hello all,
Now this post has some questions and statements in that you guys know all about and would like your valued advise and corrections/confirmations on the points.
Why A is better than B/G for voice:
B/G is congested, ie BT, Microwaves. Lots of other WLANs etc etc etc - FACT!
More non-overlapping channels - FACT!
The scatter and reflection on A is better than B/G. The idea being, the higher the frequency, the better the scatter. Would this be correct?
Higher frequencies produce better penetration results through walls, I have read. Or is it worse. Cisco say worse in the document "2.4 GHz waveform of 802.11b and 802.11g can pass through many walls. The 5 GHz waveform of 802.11a has approximately half the tendency for a given power to transmit suitable amounts of energy through walls because of its higher frequency" Ref: enterprise mobility guide. I am a little confused on this ?
A travels thru water and other moisture better than B/G, thus damp walls, wet walls, open areas (lets say between two buildings) would handle A better than B/G?
The Fresnel Zone (clearance required of an obstacle without degrading signal) is better on the A band due to a small wavelength size. Would this be a major factor for an RF design engineer? Any more technical "dummies guide" to this subject would be good?
OFDM handles signalling shortcomings like multipath fade better that previous modulations techniques (I know that G 11Mbps and above uses this also). Anyone have an English explanation to why this is? Also, please look at the graphic attached that shows the enterprise mobility guide in chaper 3, the table. What is the difference between the modulation and transmission type as many people refer to DSSS and OFDM as "modulation" I am a little confuse by this table.
Can anyone give me any more reasons and facts, and clarify any of the points above so when someone comes to me and says, "ahh, just roll out voice on B/G" I can say well this is why not?
Many thx indeed,
Ken

You have some good questions. The main reason why people are moving voice to 802.11a is the fact that there is more congestion in the 2.4GhZ spectrum. For example in a downtown area building. There are so many wifi devices out in the 2.4Ghz along with all the other interference that you get on that spectrum. 802.11a, the 5Ghz is a shorter wavelength, so the more it is susceptible to attenuation. The lower the frequency the better the signal can travel through various materials. Look at cell phones.... they are in the 800mhz or lower spectrum and they have greater distances than higher frequencies. Another reason is that if you have guest access, you have to look at devices you need supported. There might be legacy 802.11b clients or newer clients that only support 802.11b or 802.11g. So now the 5Ghz is open which give you more bandwidth for voice.
Water is an RF killer no matter if you use 2.4Ghz or 5Ghz.

Why is illustrator better than corel?

hello forumers.
im an illustrator freak,but my annoying boss wants me to learn corel ;-( ,i need some facts why illustrator is better than corel so i can shove his face in it if possible.
VIVA illi
thank you very much.

Do not, I repeat do not, ask James or Scott or Hans.
Indeed.
Only ask Jacob, who is still using a four-version out-of-date copy of Illustrator and who tries to personify it as a female idol.
If the comparison is to be "fair" (which it clearly will not be, at least from your perspective), it should compare Corel Draw X4 to Illustrator CS3 or CS4. Release dates being what they were, X4 would more legitimately be considered Draw's answer to CS3; since it long predates CS4.
Talking about earlier versions of either program is not very meaningful, except in the sense of history of development. When I compare the release histories of Draw, FreeHand, Canvas, and Illustrator, Illustrator comes in an often-embarrassing last in terms of features long taken-for-granted in other programs.
im an illustrator freak,but my annoying boss wants me to learn corel...i need some facts [that] I can shove his face..
Shove in your boss's face? For presenting you an opportunity to escape fearful dependency upon a single software?
i need the pros and cons...to outline to him why illustrator is better...
Why don't you simply welcome this opportunity to actually know something about that which you claim a completely bogus "preference"?
Were you at all interested in gaining input that would help you help your boss reach a rational and objective decision, you would at least describe something about the kind of work your boss pays you to do. What kind of business employs you? Is the Macintosh platform even relevant to your boss's business market? How large a workgroup is affected by the software choice? What kind of artwork does that workgroup produce? How is it delivered? What are its initial content sources? Who are the end-users of the artwork? In how many different ways is it delivered, and in what formats?
Yet here you are, soliciting predisposed "why Illustrator is 'better' than Draw" advice from a handful of users who, so far, admit themselves having either no, or practically no, experience with Draw! If that's not blind-leading-the-blind, I don't know what is.
You are by admission predisposed toward Illustrator, even though you are not at all equipped to say why. Reason is pointless with so irrational a mindset. Since no one responding yet seems to actually know anything about Draw, I will instead offer some ammunition I hope your boss uses to see if you are even objective enough to consider it.
The following is a just-off-the-top list. Should you actually try to counter it, you should be prepared for more:
General:
Lower cost, both initially and in upgrades
Better support for non-current versions
Faster performance
Better support for several vertical-market industries (signage, embroidery, engineering-related)
More robust CAD and more business-centric import/export formats
Better multiple page implementation
Better-organized interface
Highly-customizable workspace
Features:
User-defined drawing scales
Reliable snaps
Dimension tools
Callout tools
Connector lines
Flowchart Tools
No-nonsense, 2D vector face extrusion
Live shape primitives
Smart Drawing tools (freehand shape recognition)
Virtual Segment tool
Ability to properly cut/crop vector and raster content
Contour tool (multiple parallels)
Export selection only
Barcodes
Print Merge
Bundle for Output Bureau
Scan directly into Draw
Trim (not merely mask) vector artwork to any path
Fit Text To Path
Text stats
Export artwork as Type 1 font.
Lens Fills (live details)
Live Perspective
Object Data (spreadsheet-formatted database of user-defined object data fields)
Fillet / Chamfer / Scallop
User-defined Arrowheads
Shared Features Better Implemented in Draw:
Mesh Grads
Dynamic Guides (with increment snaps)
Independent control over Snaps for Guides, Grid, Objects, Dynamic Grids
Property Bar (far more sensible and useable than AI's poorly-designed and buggy Control Panel)
Status Bar with context-sensitive instructions
Elastic Mode (vs. AI's Reshape tool)
Add/remove/line/curve/cusp/symmetrical curve commands properly implemented for all nodes (points) in a selected path
Logarithmic and Symmetrical spirals
Macro Recording (vs. AI Actions)
Envelopes (retract envelope handles without wrecking artwork)
Old-Saw Arguements Based on Overstatement, if not Myths:
Adobe's cross-app "integration" is more hype than substantive advantage.
Illustrator's text handing is worst among Adobe apps and worst-of-class among its direct competitors.
Draw opens and creates PDFs just fine.
Claims of AI superiority regarding importing of raster images is practically immaterial. In fact, Corel Draw's interaction with Corel PhotoPaint is at least as "smooth and seamless" as AI/PS, if not more so.
Using vector artwork created in Draw (or any other mainstream Bezier drawing program) in page-layout programs is no more difficult than using AI. This stuff has been being done for decades.
Again, this is just a beginning. You do yourself a huge disservice by declaring (let alone attempting to defend) a "preference" to the only choice with which you have experience (and evidently only beginning experience at that). That's true regardless of which program you claim to "favor." How can one, with any trace of intellectual honesty, claim to have a "favorite" of anything--when one has no exposure to any of the considered alternatives?
Since you already have Illustrator, you should absolutely welcome your Boss's willingness to provide you a current copy of Corel Draw. Here's an opportunity for you--at no personal cost--to actually learn something about another program; to potentially have some clue as to what you're talking about when you claim to "prefer" one over the other; to benefit from knowing more than one particular tool, and to overcome the fear of learning your way around more than one offering among similar programs. For all you know, you may be arguing against the program you would actually end up preferring.
I could also build a bullet list of better-than-Draw AI features. It would not be as long as its opposite. Nor would the AI-favoring listings be as broadly practical.
Fact is, anyone can build a bullet list to favor any of them. (Just look at the sides of the boxes, or each vendor's self-serving "competitive comparisons" on their respective websites.) Fact is, all of them are really rather mediocre; mostly 20+ years-old technology.
You really should have no axe to grind in this, unless you can state something specific to your work that strongly favors the relatively few functional advantages of AI.

SAP EP5 SP5 Java web app problem

Hi
Recently I developed a Java web app for a Portal client. The client is on EP5 SP5 with ITS and LDAP servers (a 3 server architecture). I then used the deployment tool to create the necessary ear file and then successfully deployed it to the SAP J2EE Engine. I then navigated to the following url:
http://<portal_server>:8100/<web_app>/welcome.jsp
However I am having trouble with the following:
1) the jsp pages are not being rendered properly. in fact welcome.jsp does not have any jsp tags at all but I am still getting a compiling exception. as soon as I change the extension to .html the page is displayed fine. issue: why am i not able to view the jsp pages. error: com.inqmy.services.servlets_jsp.jsp.CompilingException ID 17013
2) the web app I have developed utilises the sapjco functionality to connect to the relevant R3 system. in my web app directory structure I have included the necessary sapjco.jar in the WEB-INF/lib directory but get the attached jco error. (I shouldnt need to set the classpath since the sapjaco.jar file must get picked up from WEB-INF/lib directory). Error: At times I get a NoClassDefFoundError stopping at the line which requires the sapjco.jar file (where it uses JCo.Pool class) and at other times I get the "could not load middleware layer".
I have tried numerous things to fix it but in vain. Any thoughts around how I could go about resolving the issues will be greatly appreciated.
Willing to provide screenshots if required.

Hi Ravi
I used the SAP J2EE Engine Deploy Tool to create the war and ear archives as well as deploy the ear archive. As I used this tool I included the required jar files inclusing the sapjco.jar inside WEB-INF\lib of the web archive (WAR). I tested this in a tomcat environment before deploying it to the portal environment.
1) The screendump is as below:
Internal Server Error 500!

I would have expected EP5 to be able to find the appropriate jar files. Especially since it has its own library of jar files to work with. I was reading some J2EE Engine doco and came across two files library.txt and reference.txt. Do I need to maintain these files as I deploy my application?
Your thoughts will be appreciated.

Hi Alon
Thanks a lot for the info!!
I have read the doco you asked me to have a look at and it sounds reasonable. But the question that I have is that is it possible to successfully include the relevant jar's in the application's WEB-INF\lib folder?? I ask this since I would expect the SAP j2ee class loader to look at the required jar's in the WEB-INF\lib folder?!? (Also the section on "Adding a Reference from a Deployed Application to a Service or Library" talks about an app that may want to use resources from OUTSIDE the application EAR.)
So if I use any jar's such as sapjco, xerces, activation and mail I will need to add them to the library.txt if they are not already there (which they should be since the portal uses them) and then add the reference in reference.txt.
Your thoughts will be appreciated.
Cheers

OC4J shuts down servlet in web-app A during deployment of web-app B ?!

Hey all,
We have a web-app A deployed to OAS 10g that contains a servlet with <load-on-startup> set to 2.
This servlet loads fine when the app is deployed.
However, when we deploy web-app B to our server, we notice in the logs that the destroy() method on the above servlet is invoked in web-app A! After web-app B is finished deploying, the init() method on the above servlet in web-app A is fired again.
What's going on?
Thanks.

I have posted this on the JDeveloper forum and been pointed in the direction of this discussion as it seems I am experiencing the same problem.....
I currently have an instance of the OC4J 10.1.2 standalone (current production version) server running, and am deploying 5 servlets to the same server. Once they are all deployed they all run fine without any problems at all.
However, if I need/want to make an update to one of these 5 servlets and then redploy it the server, the server effectively restarts terminating any open sessions that users may have on any of the other four servlets as well (i.e. users are forced to login again to the particular servlet they are using).
Is this a bug in the OC4J 10.1.2 standalone (current production version) server? or have I not set something in the deployment profile for each of these servlets/applications to prevent this from happening?
All advice/suggestions would be gratefully appreciated as soon as possible.
Thanks in advance

ASP better than JSP?

Why we need to develop online system with JSP? Why we don't just use ASP technology to develop the system since it is simple and easy to configure than JSP. Furthermore, JSP got many problems for newbie to set up the server but ASP is very easy, just need to install PWS or IIS.

Isn�t ASP using VBS? And JSP using JAVA. Probably a good reason.

Newbie-why is Indesign better than PageMaker?

Ok, I know to be current, I have to upgrade, but I don't do long documents (really past 20 pages), I liked the window shade thing in PM7, and I'm afraid those windows for everything is going to make me confused and is more time consuming...
So even tho' I have the upgrade--list your top five reasons for liking it better than pagemaker?
Thanks for your help.

Even though I do have old version of PM and Ventura, I am really liking InDesign. I have been using it since CS3 came out. It is much more fluid like when designing. It is possible to not use tags(style sheets), but I recommend using styles anyway. I haven't really been using the program long enough to have a need for using character styles, but the paragraph styles are extremely handy, as well as the object styles. But then again my needs for the program are mild compared to most that roam this forum.
One of the things that I did notice missing is the ability to switch between reader spread and printer's spread. But it is possible to manually move each page by dragging and dropping.
I think the TOC is a little more interactive it's not as intimidating to a new user as Ventura's was. I have yet to try the index feature, but I am sure it is much more user friendly as well.
Good luck...

Do I have to register all *.jsp servlets in web.xml?

All,
I'm hoping someone in this forum can help me. I'm working on a report generator that uses JSP to generate a template which is fed to a formatter. What I want is to programatically call the JSP without having to add an entry for every single report to my web.xml. As you can imagine this doesn't scale well since every time a new type of report is added, someone has to go edit the web.xml.
The options I can think of:
1) Pre-compile the JSP's
2) Have a servlet mapping where *.jsp "does the right thing" for me
3) ?
Any suggestions? I'm not sure which is the best/practical approach. I really want to get away from having to modify the web.xml for every single type of report that I can generate.
Thanks!!

Our web app is a web service where all requests get processed by an XFire servlet. So just adding the jsp on the disk somewhere won't do the trick. I have to register the jsp's.
Is there a better way to do this?

Asking help for jsp, servlet, sql, web application, web service....

i want to increase a new function in existing web site, just like let customer leave their comment for our product and collect it back to company, after modify or delete these no good one, then post it on to the website....i am a beginner,,,, wish any kind ppls can leave some comment for me...thanks a lot

Since you are a beginner, I'd advice you to take a
look at Marty Hall's website
http://www.coreservlets.com/. You can download the
first edition of his book "core servlets and Java
Server Pages" in pdf format. I like Marty Hall's books too, but I prefer Hans Bergsten's JSP book as a starter.
Try to find something about the MVC or Model View
Controller design pattern. This may seem like
overkill for small web apps, but as soon as you're
trying to add some functionality (as you want to do),
you'll see that you gain time using the MVC.
For this, I strongly recommend the "Apache Tomcat
Bible" from Eaves, Jones and Godfrey.
It explains how to install Java SDK, MySQL, Ant,
Eclipse, Tomcat.Personally, I think all this is beyond the OP. He said he was a beginner. If that means he hasn't even written "Hello, World" or compiled a single Java program, I'd say that all this stuff about Tomcat, Ant, Eclipse, serlvets, and JSPs is well beyond him. I'd discourage anyone from taking on a project like this as their introduction to Java. I'd warn his client against spending their money to buy code from a neophyte. There are plenty of talented people out there who need the work and can do the job without having to climb that learning mountain.
If I've misread the situation, I apologize. No insult intended. Just be realistic in assessing your ability and the difficulty of the project.
