Hi,
Do you have an example of using gzip with a pipe?
From Googling, only one I found is from the one below:
http://ididntknowthisyesterday.blogspot.co.nz/2008/09/pipe-into-gzip.html
using
cat myfile.txt | gzip -f > myfile.txt.gz
Will this work for binary files as well?
FYI, reason am wanting to use a pipe is due to lack of disk space, I have 500MB left and am trying to gzip a 400M file. Am assuming by using a pipe, it will use the memory instead of the available disk space while the gzip is in progress, is this correct?
I have created a WAR file by the following command:
jar -cvf myServlets.war DemoServlet.class CallServlet.html
The WAR file was successfuly created & I had deployed it on the Server.
But when I try to access the servlet through the html page, the server returns an error stating “Resource Not Available”
P.S. I had set the context-root & the application name properly.
How can I rectify this problem?
can someone tell me how many exams do we need to pass to become a ccvp. thanks
How safe is CVF?
i can enter
> java -version
but i cannot enter
>jar cvf jarfile file1.class file2.class datafile.dat
I am not sure why.
c:>java -version
java version “1.6.0_16”
Java(TM) SE Runtime Environment (build 1.6.0_16-b01)
Java HotSpot(TM) Client VM (build 14.2-b01, mixed mode, sharing)
‘jar’ is not recognized as internal or external command.
I already downloaded the latest jdk and set the path for it.
