WebStore Error Messages

Hard and soft error messages generated by WebStore help to diagnose errors during the installation of WebStore.
 
 
Server Generated Errors:
 
File not Found
Document contains no data
Internal Server Error
 
 
WebStore Hard Errors:
 
WebStore generates hard error messages for non-recoverable errors, terminating the script process.
 
File not Found
System Files not Found
Directory Access Error
File Access Error
System Error in Shopping Cart Routine
No Read Permission
Duplicated Database Id Number
Alpha Characters in Database Id Number
Invalid Frameset Tag
Product pages outside WebStore:
Form name=value Error
Invalid Query String
Product pages in WebStore:
Form name=value Error
Invalid Query String
 
Extended directory and file status messages printed for these errors are color coded: 
File errors are printed in blue.
Directory errors are printed in red.
Correct values are printed in black.
Extended error messages are suppressed when no directory errors exist. Adding env= to the query string will override extended error message suppression. This will also return environment variables present in %ENV for the current script process: 
http://www.YourDomain.xxx/Web_store/ws400CS.cgi?env=
Elements of %ENV beginning or ending with USER are always omitted.
 
Server system files used by WebStore are printed below %ENV: 
Perl Version  =  5.00503
perl          =  /usr/bin/perl
nslookup      =  /usr/bin/nslookup
sendmail      =  /usr/bin/sendmail
 
WebStore Soft Errors:
 
With the exception of frame documents, WebStore generates soft error messages for non-existent HTML files, database categories, and secondary forms called in query strings.
 
WebStore returns the client to the store's front page, displays the appropriate soft error message, and terminates the script process normally for the following errors:
 
Database Id Number not available in database
FORM File not Found
%Form not Defined
%ClientForm not Defined
%OrderForm not Defined
Invalid %OrderForm Use
HTML File not Found
No Records in Database
Invalid Database Id in Query String
Items on HTML page not available in database
 
The following error messages are printed to database category displays:
 
Image Field Syntax Error
Error in outlet.setup
Error in outlet.setup or record in outlet.data
 
The following error messages are printed to expanded item information pages:
 
Error in outlet.setup or query string on HTML page
Color and Size not defined in query string on HTML page
Item Page Error: Record not available in database
 
 
Top of Page
 
 
Server Generated Errors
 
 
 

File Not Found

The requested URL /Web_store/wseditor.cgi was not found on this server.
 
The URL and filename spelling present in href anchors must be accurate or you will receive an error message from your server similar to the message above.
 
 
Index
 
 
 
Document contains no data    Netscape browsers generate no data messages for punctuation errors present in Perl variables. MSIE browsers return Server Error messages for these errors.
 
Document contains no data messages are reported by Netscape browsers when a script process terminates prior to sending printable data back to the browser.
 
Common errors are missing commas, single quotes, or double quotes in arrays and hash of arrays in script setup files and form setup files: 
@example = ('4', '5', '0,  '1');  Missing '
@example = ('4', '5', '0'  '1');  Missing ,
@example = ('4', '5', '0   '1');  Missing ',
@example = ('4', '5', '0', '1');  Correct Punctuation
Punctuation errors in setup file variables will generate No data or Server Error messages. To debug these errors, telnet to your account and issue the following command from the parent directory of ws400CS.cgi: 
perl -w ws400CS.cgi
 
Index
 
 

Internal Server Error

The server encountered an internal error or mis-configuration and was unable to complete your request.

Please contact the server administrator, Webmaster and inform them of the time the error occurred, and anything you might have done that may have caused the error.

 
Internal Server Error messages are received for a variety or reasons:
 
#!/usr/bin/perl
Line one of the Perl script does not point to your server's Perl 5.
 
 
BINARY FTP transfer of ASCII files
FTP uploads of Perl scripts or script setup files to your server in BINARY mode adds one carriage return to the end of each line in the file. Carriage returns in Perl scripts or script setup files will generate a Server Error message at runtime.
 
With the exception of image files (.gif and .jpg) in the /Web_store/Graphics sub-directory, all WebStore files are ASCII text files.
 
 
Partial FTP file transfers
FTP uploads of Perl scripts or script setup files which terminate prematurely will generate a Server Error message.
 
The last line of text in WebStore's Perl scripts and script setup files is  # End of file.
 
 
Missing punctuation in Perl variables
@example =  '4', '5', '0', '1');  Missing (
@example = ('4', '5', '0', '1';   Missing )
@example = ('4', '5', '0', '1')   Missing ;
@example = ('4', '5', '0', '1');  Correct Punctuation

$example = 'Some Text'   Missing ;
$example = 'Some Text;   Missing '
$example = 'Some Text';  Correct Punctuation
Punctuation errors in setup file variables will generate Server Error or No data messages. To debug these errors, telnet to your account and issue the following command from the parent directory of ws400CS.cgi: 
perl -w ws400CS.cgi
 
Carriage return line termination character
Some text editors terminate lines with carriage return, line feed (CRLF). Carriage returns in Perl scripts or script setup files will generate a Server Error message at runtime.
 
UltraEdit-32 for Windows and BBEdit 5.0 for Macintosh do not add carriage returns to text files.

If the /Web_store directory was placed directly under $ENV{'DOCUMENT_ROOT'} in this example, the correct value for $basedir in ws_global.setup would be: 
$basedir = '/Path/To/Web_store';

System Error in Shopping Cart Routine

Can not create unique shopping cart file after 5 attempts.

990602024504732.cart already exists in /Path/To/Web_store/User_carts.

Error occurred at LINE 254 in /Path/To/Web_store/ws400CS.cgi.

 
Contact your host's tech support staff as your server is not properly generating random numbers. This error condition is extremely rare but warrants error handling.

If the generated cart id already exists in the /User_carts sub-directory, WebStore appends a hyphenated numeric string (maximum of three digits) to the cart id, comprised of Perl's rand, time, and *$$:
                    980406033818020-123

Duplicated Database Id Number:

  • 9 - Sweaters Category

Database id numbers must be unique to each item in the database.

Correct id numbers with ws_editor.cgi using Sort/Add or Sort/Remove.

 
Duplicate database id checks are restricted to those name=value pairs received from a WebStore form POST action. When a duplication error is detected, WebStore checks the entire database and returns a bulleted listing of all duplicated id numbers.
 
WebStore will develop an href anchor pointing to WS Editor when WS Editor is present in the same directory as the WebStore script, WS Editor is named ws_editor.cgi, and ws_editor.cgi is readable (-r) and executable (-x).

Database id numbers are numeric only (0-9) and must be unique to each item in the database.

Correct id numbers with ws_editor.cgi using Sort/Add or Sort/Remove.

 
When alpha or special characters are detected in a database item id field, WebStore checks the entire database for invalid characters in id fields. Duplicated id checking is also performed.
 
WebStore will develop an href anchor pointing to WS Editor when WS Editor is present in the same directory as the WebStore script, WS Editor is named ws_editor.cgi, and ws_editor.cgi is readable (-r) and executable (-x).
