Is it possible to use Enterprise Bean from JEE 5 server application in client application written in J2EE 1.4. What about difference in interfaces in this two technologies?
Right,
so when I set up my mock using the testing plugin's mockFor method, I expect a method
that returns null. If I do
myControl.demand.theMethod {return null}
in the debugger, the value that I set the 'theMethod' call result to is some closure in the debugger.
If I do
myControl.demand.theMethod {->return null}
the value is null, as expected.
I dont understand the difference....
Why is ++i is l-value? and i++ not
Initially there were 2 questions one was removed since that was exact duplicate. So don't down vote the answers that were answering difference between pre- and post-increment.
Lets assume myProp is @property (retain) NSString * myProp and synthesized for us....
self.myProp = @"some value";//string literal?
self.myProp = [NSString stringWithString:@"some value"];
Is there a difference here?
Is the first one a string literal that doesnt get autoreleased or is it just in memory for it's current scope and I dont have to worry about it?
what is the difference between a shallow copy and deep copy with respect to user defined types and why do we need to perform a deep copy during copy construction for user defined types??
I'm new in C# and earlier I saw the lambda expression is like
(params) => { expression;}
but in LINQ, I saw examples like
IEnumerable<string> customerFirstNames = customers.Select(cust => cust.FirstName);
No brackets.
Are they the same or is there any difference?
Thanks a lot.

It seems that somebody has subtly changed the way that parameter switches are parsed on powershell. On some machines "split-path c:\x\y --parent" works. On some it fails. Can anyone tell me a) what causes the difference and b) how can I stop it?
when I write a command
$ echo date
then it prints "date" as it is i.e it doesn't run date program.
But when I write
$ echo date | wc
then correct answer is produced as if date was run. How piping is making difference here ?
Please explain.
In the Java Generic Book, while contrasting the difference between C++ Templates and Java Generic says:
In C++, a problem arises because
without the space denotes the
right-shift operator. Java fixes the
problem by a trick in the grammar.)
What is this trick?
I was looking into Swiz framework and i felt the same of Spring. Just i felt the difference between these two is one is JAVA based and the other is Action Script based.
http://swizframework.org/
http://www.springsource.org/
My Question is:
Does the goal of the both framework is same?
Does the pattern they apply is same or different?
The concept of beans, dependency injection and IOC lies in both.
What's the difference between local/html5 on this page:
http://code.google.com/p/jquery-jstore/wiki/DefaultEngines
I was under the impression that I could use localstorage on Chrome, but looks like that's not the case?
Some elucidation would be greatly appreciated.
Thanks.
Hi,
I have recenlty stumbled into Zend Lucene port of Lucene project. I have a little bit experience with SOLR so I would like to know what is the difference between two of them especially from performance and installation side.
As much as I know SOLR requires Tomcat serverlet running in web hosting in order to work, what about Zend Lucene library?
I am also a bit confused what means "being implemented on the top of Lucene"?
Came across a line in OpenSSL that made me do a double take...
if (!*pos)
return NULL;
if (!*pos || ((*pos)->flags == FLAGS))
return blah;
Is there a (performance/security/concurrecy) difference in doing that instead of:
if (!*pos)
return NULL;
if (*pos && ((*pos)->flags == FLAGS))
return blah;
Thanks,
Chenz

I've successful installed Bouncy Castle in a Windows environment, but the same steps isn't working for Linux Ubuntu (V9.04).
Does anyone know any difference from installing Bouncy Castle in Windows and Linux? Or any bug with Bouncy Castle in Linux Ubuntu 9.04?
Does the original data type of the username string in a call to FormsAuthentication.SetAuthCookie(...) make any difference with regards to security or code maintainability?
As I understand it, the cookie is encrypted and used to identify a user on each request. I'm curious whether it should affect the design of the primary key on my Users table in my database, eg. Guid vs int or a unique username string.
I am trying to find the difference in time (without days/years/months) of two different days.
Example:
#ruby >1.9
time1 = Time.now - 1.day
time2 = Time.now
#code to make changes
#test:
time1 == time2 # TRUE
My solution:
time1 = time1.strftime("%h:%m").to_time
time2 = time2.strftime("%h:%m").to_time
#test
time1 == time2 #True
#passes
I was wondering if there was a better way of doing this? Maybe we could keep the Date the same as time1/time2?
I've always thought of the if not x is None version to be more clear, but Google's style guide implies (based on this excerpt) that they use if x is not None. Is there any minor performance difference (I'm assuming not), and is there any case where one really doesn't fit (making the other a clear winner for my convention)?*
*I'm referring to any singleton, rather than just None.
...to compare singletons like
None. Use is or is not.
Is using "self" ever necessary in Objective-C or maybe just a good practice? I have gone from using it all the time to not using it at all and I don't seem to really notice any difference. Isn't it just implied anyway?
Hi there, can anyone explain why named anchor tags would not work in safari but work fine in other browsers: ie, ff, opera, chrome.
I have some links to different areas of the same page and nothing happens when clicking on them in safari only. All the other browsers mentioned take me to that area of the page.
I have tried using both the id and the name attribute for the anchors but neither makes any difference.
