Try looking at the Tomcat implementation of HttpServlet.service() method. I have pasted it below, if you look at the service() method all it does is to check for the method and call the appropriate method. It is not recommended to override the service method. It is a good practice to only override the getXXX() methods.
protected void service(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException
String method = req.getMethod();
if(method.equals("GET"))
long lastModified = getLastModified(req);
if(lastModified == -1L)
doGet(req, resp);
} else
long ifModifiedSince = req.getDateHeader("If-Modified-Since");
if(ifModifiedSince < (lastModified / 1000L) * 1000L)
maybeSetLastModified(resp, lastModified);
doGet(req, resp);
} else
resp.setStatus(304);
} else
if(method.equals("HEAD"))
long lastModified = getLastModified(req);
maybeSetLastModified(resp, lastModified);
doHead(req, resp);
} else
if(method.equals("POST"))
doPost(req, resp);
else
if(method.equals("PUT"))
doPut(req, resp);
else
if(method.equals("DELETE"))
doDelete(req, resp);
else
if(method.equals("OPTIONS"))
doOptions(req, resp);
else
if(method.equals("TRACE"))
doTrace(req, resp);
} else
String errMsg = lStrings.getString("http.method_not_implemented");
Object errArgs[] = new Object[1];
errArgs[0] = method;
errMsg = MessageFormat.format(errMsg, errArgs);
resp.sendError(501, errMsg);

HOw to create a Batch file for java application and whats the use of this ?

HI,
How to create a Batch file for java application ?
And whats the use of creating batch file ?
Thanks in advance

First of all, you're OT.
Second, you can find this everywhere in the net.
If you got a manifest declaring main class (an classpath if needed), just create a file named whatever.bat, within same directory of jar file, containing:
javaw -jar ./WhateverTheNameOfYourJarIs.jar %*By the way, assuming a Windows OS, you can just double click the jar file (no batch is needed).
Otherwise use:
javaw -cp listOfJarsAndDirectoriesSeparedBySemiColon country/company/application/package/className %*Where 'country/company/application/package/' just stands for a package path using '/' as separator instead of '.'
Don't specify the .class extension.
Javaw only works on Windows (you asked for batch, I assumed .BAT, no .sh), in Linux please use java.exe (path may be needed, Windows doesn't need it 'cause java's executables are copied to system32 folder in order to be always available, see PATH environment variable if you don't know what I'm talking about) and use ':' as classpath (cp) separator.
The '%***' tail is there in order to pass all parameters, it only works on Windows, refer to your shell docs for other OSs (something like $* may work).
This way you have a command you can call to launch your code (instead of opening NetBeans just to see your app working). You could schedule tasks on it or just call it in any command prompt (hope you know what it is 'cause there have been people in this very same forum with no clue about it, if not just hold the 'Windows button' and press 'R', then type 'cmd' and run it).
Finally add dukes and give 'hem away.
Bye.

HI,
in genral read_text FM is used to display the Text maintained in standardtransactions like ME21n/ va01 ,,, if u wanna display this text, u shud use READ_TEXT by passing th erelavnt parametsr like object, id, text, lang.
in case o f scripts, there is no need to call this FM, when u r including the standard text using menu--include -standard text, here u shud give the object, id, text, lang..(this is simialr to standard text) then script will display the text mainatined in the standard transactions.

Yes, but you have no way of knowing whether what you find on Google is right or not.We can say its right as long google places oracle docs at the top when you type some thing related to oracle.
I aways see something else on the top. I dont believe people stopped hitting or reading or searching oracle docs.

What is the use of with and without marker update?

what is the use of with and without marker update?

Hi,
Marker Update Updates the stock values and NO Marker does not.
Generally BX upload has to be compressed with MU and BF(and UM) delta init has to be compressed with NO MU because Stock was updated with BX. And delta loads of BF and UM has to be compressed with MU because these brings new Material movements which will has to give effect to stock.

What is use of read_text in scripts

hi
what is use of read_text in scripts

Hi,
It is used to fetch the Long Text details or
Header and Items texts of a application document
READ_TEXT
READ_TEXT provides a text for the application program in the specified work areas.
The function module reads the desired text from the text file, the text memory, or the archive. You must fully specify the text using OBJECT, NAME, ID, and LANGUAGE. An internal work area can hold only one text; therefore, generic specifications are not allowed with these options.
After successful reading, the system places header information and text lines into the work areas specified with HEADER and LINES.
If a reference text is used, SAPscript automatically processes the reference chain and provides the text lines found in the text at the end of the chain. If an error occurs, the system leaves the function module and triggers the exception REFERENCE_CHECK.
Function call:
CALL FUNCTION 'READ_TEXT'
EXPORTING CLIENT = SY-MANDT
OBJECT = ?...
NAME = ?...
ID = ?...
LANGUAGE = ?...
ARCHIVE_HANDLE = 0
IMPORTING HEADER =
TABLES LINES = ?...
EXCEPTIONS ID =
LANGUAGE =
NAME =
NOT_FOUND =
OBJECT =
REFERENCE_CHECK =
WRONG_ACCESS_TO_ARCHIVE =
Export parameters:
CLIENT
Specify the client under which the text is stored. If you omit this parameter, the system uses the current client as default.
Reference field: SY-MANDT
Default value: SY-MANDT
OBJECT
Enter the name of the text object to which the text is allocated. Table TTXOB contains the valid objects.
Reference field: THEAD-TDOBJECT
NAME
Enter the name of the text module. The name may be up to 70 characters long. Its internal structure depends on the text object used.
Reference field: THEAD-TDNAME
ID
Enter the text ID of the text module. Table TTXID contains the valid text IDs, depending on the text object.
Reference field: THEAD-TDID
LANGUAGE
Enter the language key of the text module. The system accepts only languages that are defined in table T002.
Reference field: THEAD-TDSPRAS
ARCHIVE_HANDLE
If you want to read the text from the archive, you must enter a handle here. The system uses it to access the archive. You can create the handle using the function module ACHIVE_OPEN_FOR_READ.
The value '0' indicates that you do not want to read the text from the archive.
Reference field: SY-TABIX
Default value: 0
Import parameters:
HEADER
If the system finds the desired text, it returns the text header in this parameter.
Structure: THEAD
Table parameters:
LINES
The table contains all text lines that belong to the text read.
Structure: TLINE
Exceptions:
ID
The text ID specified in the parameter ID does not exist in table TTXID. It must be defined there together with the object of the text module.
LANGUAGE
The parameter LANGUAGE contains a language key that does not exist in table T002.
NAME
The parameter NAME contains the name of a text module that does not correspond to the SAPscript conventions.
Possible errors:
The field contains only blanks.
The field contains the invalid characters * or ,.
OBJECT
The parameter OBJECT contains the name of a text object that does not exist in table TTXOB.
NOT_FOUND
The system did not find the specified text module.
REFERENCE_CHECK
The text module to be read has no text lines of its own but refers to the lines of another text module. This reference chain can include several levels. For the current text, the chain is interrupted, that is, one of the text modules referred to in the chain no longer exists.
WRONG_ACCESS_ TO_ARCHIVE
The exception WRONG_ACCESS_TO_ARCHIVE is triggered if an archive is accessed using an incorrect or non-existing archive handle or an incorrect mode (that is, read if the archive is open for writing or vice versa).
Thanks,
Reward If Helpful.

Whats the difference between list and lov ?

Whats the difference between list and lov ?
i can do the same things with a list what an lov can do .
infact a list is more better. cause the list doesnt hold/show a range of values, and only has the items value iteself.
while the lov can get all the values of items depending on the query.
like
select ename, job, sal from emp
will show all the three items values in lov?

Also, if you're looking in the US store, the prices are:
- Airport Express (small, no ac) $99 - Has audio out for speaker connection using Airplay. Can share a USB printer only.
- Airport Extreme (larger, ac) $199 - No audio out, can share a USB printer or hard drive.
- Time Capsules (2TB, 3TB at $299, $399) - have ac wireless and a backup hard drive for Time Machine which the other Airports do not have.

Whats the difference between Fatal1ty and Fatal1ty USB heads

Whats the difference between Fatal1ty and Fatal1ty USB headset? What is the $30 price difference for other than a USB connection?
Also, what is the advantage to using the USB port?
Still trying to decide on which headset to buy. I will be using these mainly for gaming and some music. Although i'm not real picky when it comes to music quality. Even considered the HS-1200 wireless. Which headset of these 3 has the best sound quality and better quality?

Any USB sound related item is going to use system resources instead of the non usb version. The non usb version uses the resources of the sound card and not system resources. So you should get cleaner sound with the non usb version.
But, be aware creatives tech support is not the best in the world. Keep that in mind when buying a product from them.
