Regular expression problem - pls help

I would love to have a reg exp that checks for:
a-z
+0-9+
+'_'+ as well as +'-'+
as well as the DOT character.
How can this happen ?
I have tried both:
[a-z0-9_-\\Q.\\E]+as well as
[a-z0-9_-\\.]+and I am given:
java.util.regex.PatternSyntaxException: Illegal character range near index 10
[a-z0-9_-\Q.\E]+Please help
Thank you

No, because it is not a metacharacter as defined by the Pattern javadoc.
What's going on still remains a mystery to me as of now.???
but it has very definite meaning as the range operator when used in a regex, and the strange thing is that you use it yourself in this defined meaning:
[a-z0-9_-\\Q.\\E]+{code}
How can you see that it doesn't need to be escaped when here you use - to show the range for letters and numbers: a-z and 0-9?

Urgent: Sessions problem pls help me

Hi all,
Its already late to post this problem.pls help me urgently.
I have a servlet & two jsp's. first i request servlet, it processes something and forwards request to my first jsp. In that jsp on a button click, i'm displaying a new popup by calling showModalDialog. this dialog gets data from the same servlet but it forwards to my second jsp.(second jsp can be seen in dialog)
Now if i submit form from my second(dialog) jsp, the servlet reports that session has expired. I tried a lot but invain. any one who helps me is appreciated well by all of our forum.
waiting 4 u r reply,

It could be that you have cookies turned off and you're not using URL Rewriting.
In J2EE, the first time your browser makes a request to the server, the server responds and appends a SESSION_ID parameter to the request as well as storing a cookie with the SESSION_ID.
The second time your browser makes a request, the server checks for the cookie. If it doesn't exist it checks for the parameter. If neither exist the server assumes its the first time your browser has made a request and behaves as describe in the previous paragraph.
In your case when you submit the form if you have disabled cookies and the action attribute doesn't have the SESSION_ID paramter appended to the url, the browser will assume it's a first request. The user will not be logged in, hence your session has expired error.
To fix this you need to encode the URL in your JSP. You can use the struts html:rewrite tag or the HttpServletReponse.encodeURL method, or if you're using JSP 2.0 the JSTL c:url tag.

How to solve this problem, pls help when, I try to see remote camera system(spec dvr) from home. The Error I get is "Dual streaming is required for HTML viewing"

I had the same probelm and found that the problem lies with 64bit programs such as safari and microsoft internet explorer. I have resolved the issue on my PC based server by using a 32 bit ie and same on my mac by using the same running windows under parallels.
So far the problem with the 64 bit side of it is still to be resolved.
Hope this helps and gets you guys up and running until suchtime a 64 bit solution is found.

Interesting Regular Expression Problem

Hi - I am fairly new to Java, but have some reg exp experience.
Basically, I would like a regular expression to strip elements out of a text format. The elements are delimited by curly braces, very similar to Java. The problem is that the elements may contain other elements - the format is hierarchical. I need to extract the whole element, including its children.
For example, I need to extract the B element from
[A]
a1 1
a2 2
b1 1
b2 2
[C]{
c1 1
c2 2}
[C]{
c1 3
c2 4}}
and the answer should be
b1 1
b2 2
[C]{
c1 1
c2 2}
[C]{
c1 3
c2 4}}
The nature of the format is not fixed - I won't know how many child elements the B element contains.
Can this be done using regular expressions, or do I have to write a custom string handling function?
Thanks for any help.

:-) And I still don't understand it!It's quite easy though ;-) Suppose a word w is generated by some grammar.
If this grammar is regular you can write word w as xyz where y is not the empty
word and |x| < p. if w is generated by a regular grammar then xy^nz
(n occurrences of y) can also be generated by the same grammar. That's
the 'pumping' giggle part.
Now suppose the language of nested parentheses is a regular language.
All you have to do is find a word w = xyz where xy^nz is not part of the language.
Let w= ((())) and x= ((, y= ( and z= ))), obviously xy^nz is not a properly nested
parentheses word for n > 1. Note that every generated word in that language,
long enough has to have that value p, where xy^nz |x| < p and xy^nz in the language.
The pumping lemma giggle for context free languages is almost the same:
you have to find two positions where the pumping fails/succeeds.
kind regards,
Jos (huhuh, he said 'pumping' ;-)

Simple regular expression problem

Hello,
I need help with regular expressions. I have a situation when I need to get data from one table to another and I think my problem can be solved using REG EXP, but I don't know how to use them properly.
I need to seperate varchar2 fileld whcih is basically number/number into 2 seperate number fields
CREATE TABLE tst (CODE VARCHAR2(10));
INSERT INTO tst VALUES('10/15');
INSERT INTO tst VALUES('13/12');
INSERT INTO tst VALUES('30');
INSERT INTO tst VALUES('15');
CREATE TABLE tst2 (po NUMBER, co NUMBER); I need to get code into co and po columns. I think result should look something like this, but:
INSERT INTO tst2
SELECT regexp_substr(CODE 'something here to get the number before /') AS po,
regexpr_substr(CODE 'something here to get number after') AS co
FROM tst; Any help appreciated

Hi Blu,
Yes, I have tested with "0" in the figure (like 10/20 30/40). And it worked that time and then I replied. :) :)
But Still it has a problem in pattern and rectified it below.
Like :-
SQL> select regexp_substr('10/40','[^/][0 9]',1,2) DD from dual;
DD
40
But if I (The way you test) use a non zero value like 43 ; below query will not return 43.
SQL> select regexp_substr('15/43','[^/][0 9]',1,2) DD from dual;
DD
My pattern has a slight mistake("-" missing between 0 and 9) and I changed and retested . Correct pattern - '[^/][0-9]' and now it will return 43..
SQL> select regexp_substr('15/43','[^/][0-9]',1,2) dd from dual ;
DD
43this '[^/]+' pattern also works fine.
Thank you for pointing out Blu; as I came to know lot more about patterns.

Regular Expressions - Problem

Hi @ all,
I need a complicate regular expression, I don´t know.
I have a big folder with many .htm pages (800-1000) and I have to do the following:
http://www.domain.de/ab%32-xyz?myshop=123
I have to delete the "ab%32-xyz", the problem is, that in this are, there could be every symbol, letter or number.
So the area between "http://www.domain.de/" and "?myshop=123" (these 2 areas are everytime identical in all documents) shoud be deleted.
Could everyone say me, how to do this with regular expressions in dreamweaver?
Thanks,
Felix
P.S.: Sorry, my Engish is not so good, I´m from Germany

Do you want to replace the random text with anything?
If not, this is how you do it in DW:
Make a backup of the folder you want to edit, just in case anything goes wrong
Edit > Find and Replace
In the Find and Replace dialog box, select Folder from the "Find in" drop-down menu, and select the folder you want to work with.
Select Source Code from the Search drop-down menu.
Put the following code in the Find text area:
(http://www\.domain\.de/)[^?]+(\?myshop=123)
Put the following code in the Replace text area:
$1$2
In Options, select the "Use regular expression" check box.
Click Replace All. Dreamweaver will warn you that the operation cannot be undone in pages that aren't currently open. As long as you have made a backup, click OK to perform the operation.

Regular Expression / replace Function Help

The problem:
cfset myString = "i am a big boy"
cfset outputString = replace("i am a big
boy","i","you","all")
Wrong Output:
you am a byoug boy
Intended Output
you am a big boy
How do I achive that output.

Your first example had only one sentence. That's why I gave
that answer.
Anyway for your real question, you need to use regular
expressions
#rereplace(myString,"i\s","you ","all")# - will give u
you am a big boy you am a big boy you am a big boy you am a
big boy.
\s looks for a whitespace character after the letter i. So
that way it will not change the letter i in big

Regular expression problem?

Hi I have a file which contains the following text
<cfset objNews.strNewsTickerLink =
"index.cfm?pageid=83">
Now what i'd like to do is to scrape out the value of this
variable i.e. 'index.cfm?pageid=83'. Now this variable can be
different.... so basically whatever the value of the variable
objNews.strNewsTickerLink is set to.. I'd like to get it out. Now
I'm not that great with regular expressions... can anyone help me
out?
Thx

Hi,
One way of handling that is to use this UDF,
http://cflib.org/udf/queryStringGetVar
But, you must be aware of the url variable that comes after
"?" symbol in order to use the above udf. If it is dynamically
generated you need to write your own regular expression.

Find/replace and regular expression problem

Hello, i'm using find and replace with a regular expression
for the first time. I have it checkmarked and it's finding my text
but it's missing (not highlighting) the ')' at the end of the line.
Here's my code:
[($[0-9]+US)]
it's supposed to find everything inside the square brackets -
but it misses the closing parenthesis after . I need
to find this string and replace with nothing to remove the string
from any/all pages. Is there a reason why it's missing the closing
parenthesis? I was actually able to add a few more parenthesis
(e.g. "))))") before OR after the closing square bracket and it
still found the original text minus the closing bracket and the
extra parenthesis didn't prevent the text from being found.
Any help is appreciated!

That's not how square brackets work
Try:
$\$\d+US$
A left parens, followed by the dollar sign, followed by at
least one
digit, followed by US,
followed by a right parens.

Import problem,pls help!

Hi,there,
I'm new guy here,I'v got a problem about Import in table mode,I found I can import back all records successfully, but it just appends all records into the orignal table,not overwrite
it,for example, I made a export for a table with 2 records, after then I added some records into that table,
finally I made an import for that table, I found the
total of records is not recovered to 2,but just append
the records from export file,why can't I recover it to 2
record? pls help me,thanks!

All that import does is to run a bunch of SQL statements based on the content of the export file. If you look at the export file in an editor (if its small), or through type (on Windoze) or more on *NIX you will see stuff like:
CREATE TABLE x STORAGE ( ...)
INSERT INTO x col12,col2, ...
VALUES (:b1,:b2, ...
If you give imp the paramter ignore=Y, then the error generated by the CREATE TABLE (table already exists) will be suppressed, but the ata will be inserted. Note that there are no DROP TABLE or TRUNCATE TABLE commands in the export file.
If you want to restore your database to a particular point in time using import, then you will need to manually drop or truncate the tables first. You can generate the required sql from the data dictionary. something like
SET lines 1000 pages 0 feedback off trimspool on;
SPOOL drop.sql;
SELECT 'DROP TABLE '||table_name||';'
FROM user_tables;
SPOOL OFF;
@drop.sqlHTH

Hi
Sorry khar khar ???? Mainly any sounds from under the keyboard would be Fan or HDD either way could mean either the Fan ( if fan ) is struggling to move due to dust build up OR the hard drive is failing ,,, It's difficult to give you a firm answer without more information . Can you tell the difference between the fan noise and a hard drive noise ?? When you start up from cold does the noise start immedietly or is it only heard after say 5-10 minutes ?????? Checkurtech
