Jar all the servlets?

Hi,

I heard that it is better to jar your servlets rather than keep your classes

in web-inf/classes in a web application....Is it so?

If so whats is the reason...?

Thanks in advance..

Portability, if that's important to you.

I can't see any

I will jar up tag libraries into a nice and tidy package. And any classes or servlets that are part of "frameworks" or other systems meant to be shared across multiple web apps. But for servlets that are speicfic to a particular web app, I just put those under WEB-INF/classes.

Thank you....

but i dont think that there are no security issues involved if we

dont keep the classes as a jar....Isnt it so?

Regards

It is as secure to put them under the classes directory as it is to put them in a jar under the lib directory.

Thank you...Satou

I found classes more convenient for development for some servlet containers, you can replace just a single .class or .properties without jarring. From other side I use signed jar which includes a servlet, a web started app and applet, so see one jar for everything!

Sorry i didnt get this..

compiler will give preference to load .class files present in classes folder and then it loads .class files present in jar. and there is no difference. but when u deploy u r applicaion from one server to another it will be easy to deploy if ur application is in the form of jar.

sai prasanna, JavaRanch is a community of people from all over the world, many of who are not native English speakers. While using abbreviations like "u" instead of spelling out "you" is convenient when text messaging your friends on a cell phone or in a chat room, it presents an extra challenge to those that are already struggling with English. Additionally, such shortcuts may confound automated translation tools that patrons of the Ranch may be making use of.

I would like to ask for your help in making the content of JavaRanch a little easier to read for everybody that visits here by not using such abbreviations.

Please read this for more information.

classloader will give preference to load .class files present in WEB-INF/classes and then it loads .class files present in jar. If same name is present in both precedence is given to WEB-INF/classes.

clients cannot access files under WEB-INF directory as it is private to web container. only container can access files under WEB-INF(so security issues doesn't come here)

jar files are easy to distribute

Which class loader? Why? Easy to distribute in jars? Have you heard about war or ear? All classes you developed have to be stored under classes. All classes you got as is should be stored under lib.

Completely false. You can jar up your own classes if you like and put them in the lib folder.

You could also unpack a third party jar file and put the class files under the classes directory. There is usually no reason to do so, but you could.
