Tar-ing and zip-ing files after a specific time frame - HELP NEEDED

Hi,

I have a script which is to perform the following task:
1) check for files in a particular directory.

2) The directory should contain 4 files in the form of:
<OSSInstance>_<OSSName>_BSC<Nokia BSC ID>.<counter no>.<YYYYMMDDHHMM>.<gid>

whereby:
OSSInstance - a combination of alphanumeric characters
OSSName -a combination of alphanumeric characters
Nokia BSC ID - a combination of alphanumeric characters
counter no - Digits 1,2, 3 and 72 only
YYYYMMDDHHMM - basically a numeric value denoting timestamp of the file i.e. 200603130500
gid - a numeric value for a particular process

An example of the file is shown below as:
1003_oxnn2_BSC48379.72.200603130500.768751

3)There is a timeout period in the script which checks if these 4 files are available within the particular directory.These 4 files are being transferred remotely from some machine.

4)If ALL 4 files are already in the directory within the specified timeout period, then it's copied to another directory where it's tar-ed and gzip-ed.

5)If one(1) of the 4 files are not the directory within the specified timeout period, these files are copied elsewhere and their names written into a log file.

6) The timeout period in waiting for ALL 4 files to arrive is 5 mins.

However I've encountered some problems within the script, which is captured below:

Re: Separating ANT builts

Hi jwenting,

From the example you had provided(see below), you seemed to have basically included the dependencies of the targets of interest - but how did you conditionally exclude the other target types/rules that are currently in the ANT build file without having conditions in them? Could you please help explain?

Thanks
Danny

Java FlexLM API

HI,

I'm new to the licensing mechanism, and I would like to gain an understanding on the Java FlexLM API usage.

I was wondering if anyone could point me to any examples or share any of their references as to how the FlexLM Java APIs are being used to segregate the certain components from the from the entire software packaging based on the licenses available ?

Thanks

Separating ANT builts

Hi,
I'm a newbie with ANT. I have a ANT build.xml file in which I'm attempting to separate certain packages from different requirements of the built.

As an example, if I have a software which consists of packages A,B,C,D and E. I have customer whom are purchasing the software, but are not interested in the incorporating packages D and E. The customer is only interested in using packages A,B and C. At the same time, I have another customer who is interested in using the entire package of the software i.e. A ...E.

How do I implement flags in ANT to ensure that certain components are not accessible by the customers if they are not being purchased?

From the attached is my build.xml, I'm attempting to exclude the following targets(listed below) so that users could not access them if they have not purchased the software with these features:
<target name = “activeCollector>
<target name = “activeGUI>
<target name = “saagui>

From the build.xml, the final built would produce 2 *.jar files i.e.
Poller_Admin_Installation_V2.0.jar
Poller_Client_Installation_V2.0.jar

Could anyone show me an example how I could implement flags in ANT prevent users from accessing certain packages within a software?

Thanks
Danny

getting values from drop down menu

HI,

I wish to get the values from the drop down menu selected by a user from the HTML page and pass this value into my servlet program for processing.

In my servlet program, I've used the getParameter() function to obtain the value from the drop down menu selected.

<SELECT name=Day> 
<OPTION value="" selected>- Select -</OPTION> 
<OPTION value=Sunday>Sunday</OPTION> 
<OPTION value=Monday>Monday</OPTION> 
<OPTION value=Tuesday>Tuesday</OPTION> 
<OPTION value=Wednesday>Wednesday</OPTION> 
<OPTION value=Thursday>Thursday</OPTION>
<OPTION value=Friday>Friday</OPTION>
<OPTION value=Saturday>Saturday</OPTION>

</SELECT>

String days= request.getParameter("Day");
System.out.println("DAY =" +days);

However, the value of the parameter "day" seems empty. May I know what is the correct method of getting the value selected from the drop down menu into my servlet? It did work when I use Javascript functions to extract it though (function getDay() in frmLockOut.html).

Attached are my JSP(frmLockOut.html) and Servlet(AdmProfileLockOut.java- see function add( ) ) source code files for reference.

Thanks
Danny

Removing characters from a string

Hi,

I'm a junior computer science student and I'm currently new to this forum.
Im having some problems understanding the code excerpt from a book (see code excerpt below). The code is suppose to delete characters from a string, based on the given prototype:

void RemoveChars(char str[], char remove[]);


str[] contains the entire string e.g "Hello World" while remove contains the characters to be removed from str[] e.g remove[]={'e','o','r','d'}; Once removed str[] should now be: "Hll Wl"


void RemoveChars(char str[], char remove[]){
int srcIndex, destination, removeArray[256];


// Initialize all elements in the lookup array to be 0.
for(srcIndex=0; srcIndex<256; srcIndex++){
removeArray[srcIndex]=0;
}


//set true for all characters to be removed
srcIndex=0;
while(remove[srcIndex]){
removeArray[remove[srcIndex]]=1;
srcIndex++;
}


//copy chars unless it must be removed
srcIndex=destination=0;
do{
if(!removeArray[str[src]]){
str[destination++]=str[srcIndex];
}
}
while(str[srcIndex++]);
}

However, my problem is with understanding the statement :
removeArray[remove[srcIndex]]

My understanding of that statement is remove[srcIndex] returns the character to be removed, and that character is then used as an array subscript for the array removeArray[remove[srcIndex]] ??

My understanding of such array notations are such:

int size=10;
int grades={1,2,3,1,1,2,3,4,5,3};
int frequency[10]={0};


for(int i=0;i<size;i++){
++frequency[grades];
}

In this case, grades returns the numbers from the grades array i.e. 1,2,3, etc ...which is in turn used as an index to the frequency array to increment the freqeuncy of occurence for the particular grade.

Could anyone help me out in clarifying the earlier notation of removeArray[remove[srcIndex]] ?

Thanks
Danny

Re: String to integer conversion

Dave, Alok & Jwenting,

Thanks very much for the help. In fact I forgot to mention earlier when posting this problem that I'm not suppose to use built-in functions like atoi or atol for such conversions. Nevertheless, thanks to everyone for their help.
:D

Dave,
Your solution provided the answer to my problem. thanks. :D

Danny.

String to integer conversion

Hi,

I'm a freshman in computer science and a new member to this forum. I'd like to convert the string representation of a number e.g "456" into its integer equivalent i.e. 456.

As for character representation of single digits e.g. "6", I'm able to convert it to its integer equivalent by doing:
char myChar = "6";
int asciiVal = myChar - '0'; //produces the integer 6 now.

Could anyone show me how the string representation of a number like "456" can be converted to its integer equivalent?

Thanks
Danny
