Hey,

I have some command, I'll call it "command".

I need to do this:
yes | command
but without a pipe, there is a reason for this, because for the specific use, pipe before the command
is not allowed, that's not the point.

Is there an alternative I can use which will output do the same thing without the pipe ?
Maybe something like this:
command < yes
(which will not work because it expects a file, and not a command)
?

Or some other simple way ?

Thanks

Actually, I managed to do this partially (with help).
After the site, e.g. 'test.com' added the CNAME, I did so when users enter [url]https://test.com[/url], they will see [url]https://test.com[/url] as the address, where they are actually at [url]https://mysite.com/test.com[/url] - as I wanted.
However, now they get a message from the browser that this site is not secured, because a SSL certificate is missing. So now, all that missing is that 'test.com' will buy a SSL certificate, give me the details, and I should proceed with 'openssl' command, like this:
[url]https://knowledge.rapidssl.com/support/ssl-certificate-support/index?page=content&actp=CROSSLINK&id=so6411[/url]
and then:
[url]https://knowledge.rapidssl.com/support/ssl-certificate-support/index?page=content&actp=CROSSLINK&id=SO6252[/url]

Am I right about the last steps ?

Thanks

Hello
I have a question:

Suppose I own a site, and a domain, 'mysite.com'.
I provide services to different clients, so clients open sub-domains under my site.
For example, the site 'test.com' will be at my site, at 'mysite.com/test.com', so the clients of 'test.com' will enter this sub-domain.

What I want, is that instead of this, the clients will enter 'test.com', and will see 'mysite.com/test.com'. Offcourse I want that all its sub-sub-domains, e.g. 'mysite.com/test.com/service2' will also be seen like 'test.com/service2', so simple redirect or something like that is not what needed.

The process is:

  1. The client, 'test.com', will add a CNAME ( [URL="

Does the GC clear memory of running threads with no reference to them ?
Consider the following code:
[CODE]
Thread t = new Thread()...
t.start();
t = null;
.
.
.
[/CODE]
Suppose 't' runs forever, and the rest of the program runs forever - will the GC clean 't' from the memory (stop it in the middle of the running) ? It's running but it has no reference to it.

Please if you have link to an official page from SUN/Oracle that support the answer, write it here, because I searched and did not find an official answer to it.

Thanks

OK, i was not clear enough.
x,y,... are variables, but not from the user.
It's true that I can do:
query = "SELECT ... FROM ... WHERE user = ? AND password = ? AND x='"+valuex+'" AND y='"+valuey+"' ..."
It will give me what I need, but it's not so readable.

Therefore, I want something like:
query = "SELECT ... FROM ... WHERE user = ? AND password = ? AND x=? AND y=? ..."
PreparedStatement preparedStatement = ...
preparedStatement.setString(1,userValue)
preparedStatement.setString(2,passwordValue)
execute(query,preparedStatement,new Object) ?

Hye
I have a question:
Suppose I use JDBC, JDBCTemplate in order to execute a sql query.
The query is something like:
query = "SELECT ... FROM ... WHERE user = ? AND password = ? AND x='valuex' AND y='valuey' ..."

Where user,password - I got from the web user - so I want it to be in a PreparedStatement.
But x,y,... (Suppose there are many variables like this) are values which I set their values myself at the code (e.g. constants), so there is no use for PreparedStatement on them.

Is there a way I can combine the two ways, something like:
PreparedStatement preparedStatement = ...
preparedStatement.setString(1,userValue)
preparedStatement.setString(2,passwordValue)
execute(query,preparedStatement,new Object) ?

If there is, please write me an example of this part of the code, how can I do this exactly.

Thanks

Gribouillis :
Thanks !
That's exactly what I need ( I think ).
When I do it with "streams.py < dsc01390.jpg > tmp.jpg", I mean from a file to a file,
it copy it exactly, as I need.
Although when I just want to see the file printed to the screen, when after I write the previous line, I write "streams.py < tmp.jpg", I see junk, and not bytes as my first attemp ("b'b\'\x1c\xa9...").

  • I did not write "chmod +x streams.py" command, I suppose it is not neccessary ?

( It is only in Python 3 ! )
( The commands to operate this file are at Linux ! :
I want to read a file, but it has to be through stdin ( In linux, with "< filename" ) !
And I want to write the same file to another file with a different name ( In linux, with "> newfilename" ).
)

Hello.

I have written the following code. The code should read bytes (!) from a binary file, and write them to another file.
It's like copy the binary file, but get it through stdin, and write it to stdout. It has to be through stdin / stdout.

testFile2.py:
[code]
import sys

def make_streams_binary():
sys.stdin = sys.stdin.detach()

sys.stdin = codecs.getwriter("utf-8")(sys.stdin.detach())

#sys.stdout = sys.stdout.detach()
#sys.stdout = codecs.getwriter("utf-8")(sys.stdout.detach())

make_streams_binary()

while 1:
try:
file = input()

    except KeyboardInterrupt:
            #print("ctrl-c")
            break
    except EOFError:
            break

print(file)
[/code]

And to test the code:

cmd: python3 testFile2.py < Viper2.jpg > test_output.jpg

Printing the files to the screen to see the difference:

cmd : python3 testFile2.py < Viper2.jpg

It is almost the same file. The original takes 990 bytes, and the output file is 1219 bytes.
As you can see the difference between the files: At the orig file, there is one '\' every few chars, and the output has two '\'.

I tried to run the third line at make_streams_binary() and it did weird stuff.

Can you ...

About the makefest:
The eclipse should do this for me, and no, it does not. Actually, the action of the jar making is not finished. When I open the jar file that created, the mainfest in it is pretty much empty and without a main-class definition. But even when I edit it and add the main class line, it has a java error when i click it.

I made a runnable jar to this project about 1-2 month ago, and the mainfest file was long, and the mainfest folder contained a lot of things, maybe beacuse it's an Apache Tomact Project ? or has a lot of jars ? I don't know, i need to start it regulary...

  • At other projects it's working.

I try to do in eclipse: export -> java -> Runnable Jar... but it tells me:
could not find main method...
[IMG]http://i43.tinypic.com/nbapux.jpg[/IMG]
but in my main class I defined it it has:
public static void main(String[] args)

(the file is created, but when i double click it - java exception...)

Maybe this will help to:

  • I use a lot of jars in my project, which exist in the same folder of the project and added to build path, and also I manually added user libraries.

I would really appreciate help with a solution.
thanks

Hello
I want to implement this function:
boolean check(String str,String exp)
that gets a string, and an expression and see if it mathches.
But (!), according to a format by '' (maybe similar to the SQL LIKE statement, but with instead of %).
Examples of tests of this function that should work:
[CODE]
boolean b3=check("55-210.txt", "55"); // starts with 55
assertEquals(b3,true);
boolean b5=check("f1.txt", "
.txt"); // ends with .txt
assertEquals(b5,true);
b=check("897", "8
8*"); // 8...8...
assertEquals(b,false);
[/CODE]

I don't mind, and even prefer to use existing external jars that can help, like Jakarta RegExp, JOSQL, and such.

Thanks in advance
