Hi all,

I know the title means nothing, but what i want is, e.g. :

Given I have three sets. They have the same size (e.g. 100, indeed the size is not important). I want to get 100 objects from the three sets, but the number of each set needs to be close, e.g. set1 33, set2 33 and set3 34.

Is there any mathematical model can achieve above scenario?

HI all,

I dont' know if 'Spring' is the correct group to ask my question. I'm new to the AspectJ. I have the following code:



I'm using the Aspecj annotation to declare the pointcut. The following is my code:


However, the method pointCutTest is never called when the method executeBatch is called in its implementation class. How can i set the pointcut for the method executeBatch in the implementation of PointCutIWantToSet?

First, the regex you wrote is telling me that the String must begin with "SchemaValidationException" or it must not have Caused By ...

I believe that you are seeking something like: ([a-Z]|[0-9])*(SchemaValidationException|!(Caused by: org.xml.sax.SAXParseException: cvc-minLength-valid: Value '' with length = '0' is not facet-valid with respect to minLength '1' for type 'NonEmptyString'.))+([a-Z]|[0-9])*

I recommend trimming the String since spaces complicate the regex and one missing space might ruined your method.

That would be with regex however from your test case seems that indexOf would be easier to apply.



Thank you for your reply. As I said I had to use one regex to finish the following checking:

1. Check if the string contains A
2. If the string contains A then check if the string doesn't contain B

I've simpified the example. Hopefully someone can fixed the problem.

Thank you in advance

Yes. DON'T.

Regexes were designed for (originally) string patterns contained in a single line and, although they've been expanded to include multi-line matches, I'd suggest that whatever regex you come up with is likely to be unwieldly.

Seems to me that you are searching for two patterns in a multi-line block, so my pseudo-code would look something like:but I'm quite sure there are other solutions.

Winston

[Edit] @pkinuk: Above is not quite right. You shouldn't read a new line in the outer loop if a match on the 1st string was already found; I leave it to you to correct.



thank you for your reply, I wished I could use the yr pseudo-code do check the string. It was one of the requirements from our client: we have to use one regex to check the following conditions:

1. Check if the string contains ‘A’
2. If above condition return true, then check if the string doesn't contain the 'B'

The easiest way to do this is to have a negative look-ahead (generally from the beginning of the regex) attached to the regex search for the item that you want. With the negative look-ahead, the regex will always fail, if it finds the component that it doesn't want.

Using look aheads is pretty advanced, so I suggest that you start there, but don't be surprised if you run into trouble and have to backtrack to learn other parts of regex first.

Hi Henry, thank you for your quick reply. I did apply the negative look-ahead, but it failed, the Matcher.find() returned true. The following is my code:

The regex i used is

SchemaValidationException(?(?!\QCaused by: org.xml.sax.SAXParseException: cvc-minLength-valid: Value '' with length = '0' is not facet-valid with respect to minLength '1' for type 'NonEmptyString'.\E).)*(?:\s)*)*



However, the Matcher.find() returned true, while the Matcher.group() is

Hi all,

I'm new to EJB. I'm reading the book 'Mastering Enterprise JavaBeans 3.0'. I tried to run the HelloWorld example in chapter 3, but I couldn't see the text 'hello()' & 'Hello World' in the eclipse console context. I also tried to open the glassfish log file, it didn't show neither. Would you please help me to solve this problem?

Thank you in advance.

The following are the source code:

Then your expectation was wrong. What you describe is exactly how browsers implement the basic authentication method. They ask the user for the credentials once per browsing session and cache the credentials.

So if you want something different -- and you do -- then you can't use basic authentication.



Thank you for your reply. Does it mean I need to use FORM Authentication to achieve my goal?

hi Jayr Motta,

Thank you for your reply, I tried to google the topic how to remove auth header, but i couldn't find a suitable example. Could you please give me an example or a example page?

What I've done is create a Filter implementation class, in the doFilter method:


unfortunately, the login page didn't show up when the current session expired if I clicked the link again. Here is my filter setting in the web.xml file


Thank you in advance.

Hi all,

Here is my scenario:

1. I set my application using the BASIC auth-method in the web.xml file


2. Set the security-constraint like:


3. Set the session time out as 1 minute:
