IMPORT statement understand

Hi All,
Can you please help me regarding below code.
IMPORT
EINZELNACHWEIS_LOESCHEN TO %_P0000000001
H_ART TO %_P0000000002
NO_KEKO_CHECK TO %_P0000000003
T_KEKO TO %_P0000000004
T_KEPH TO %_P0000000005
FROM LOGFILE ID %_KEY.
If is it from memory then it will get the data from memory.
here we are importing the data from LOGFILE.
so from where we are getting the data from the aboue statement.
Thanks
Sriman.

Hi,
How can i find out that particular export.
I am debugging CK40N.transaction after giving the inputs.
in that mode in one standard program i got the code like this.
from that statement i got the data into internal table.
Now how can i findout where it was exported(which program).
Thnaks in advance.

Import statement .. what does it do ??

Hi All,
What is IMPORT statement doing ??
IMPORT order_items_in to w_order_items_in from MEMORY ID
'FREEGOODSTERMS'.
can you kindly explain what this statement is doing ?
I was by my friend that this is used to pass order_items from one session to this sesssion, but when I searched for FREEGOODSTERMS, I could find export after this statment. I was wondering how can import me first and then export.
Please let me know.
Thanks
venkat.

Hello Venkat,
Sorry for late reply..
Please see the program which other program submitting somewhere.
if they are using multiple purpose then export and import statement may possible in one include.
Best way just use where used list for that include and other programs searching like export and submit..
For better understanding about export and import then see the below sample programs.
Create one program and paste below code :
REPORT ZTEST_AMEM1.
tables : lfa1.
data : begin of i_lfa1 occurs 0 ,
       lifnr like lfa1-lifnr,
       name1 like lfa1-name1,
       land1 like lfa1-land1,
       end of i_lfa1.
start-of-selection.
select lifnr
       name1
       land1 from lfa1
       into table i_lfa1 up to 100 rows.
Export
export i_lfa1 to memory id 'SAP'.
submit ztest_amem2 and return.
write:/ 'hello'.
Now create one more program and paste below code :
REPORT ZTEST_AMEM2.
data : begin of j_lfa1 occurs 0,
       lifnr like lfa1-lifnr,
       name1 like lfa1-name1,
       land1 like lfa1-land1,
       end of j_lfa1.
start-of-selection.
import i_lfa1 to j_lfa1 from memory id 'SAP'.
loop at j_lfa1.
write:/ j_lfa1-lifnr,j_lfa1-name1,j_lfa1-land1.
endloop.

Import statement and directory structure

First of all, sorry for such a long post, I believe part of it is because I am unsure of the concept of importing in Java. Secondly, Thanks to anyone who can ultimately enlighten me to the concept of import. I did ask this question before in the "erorr and error handling" forum, and the people who have helped me there did a great job. But, I believe I require a little more clarification and thus have decided to post here.
Anyhow, my question..
Could someone explain to me the concept of the import statement, or direct me to a webpage with sort of explanation for newbies? For some reason, I am having a hard time grasping the concept.
As I understand it, the import statement in Java, is very similar to the namespace keyword in C. That is to say, import doesn't actually "import" any source code, the way that the #include statement does in C.
So I suppose what my question is, say I have a java class file like below:
//filename: sentence.java
//located: c:\school\csc365
package csc365;
class sentence
//some variables here..
//some constructor here..
//some methods here..
And some sample program like the one below which implements the above..
//filename: test.java
//located: c:\school\csc365
import csc365.*;
import java.io.*;
class test.java
//creates some sentence object
//uses the object's methods
//some other things.
As I understand it, the test.java file should not compile because the csc365 package is not in the correct directory. (assuming of course, the classpath is like c:\school\csc365;c:\school )
But, ... where then should the sentence.java be located? In a subdirectory of c:\school called csc365 (i.e c:\school\csc365\) ?
And thus that would mean the test.java file could be located anywhere on the hard drive?
I suppose, I just need a little clarification on the correlation between a package's "name" (i.e package csc365; ) and its corresponding directory's name, and also how the javac compiler searches the classpath for java classes.
..So, theoretically if I were to set the classpath to look in every conceivable directory(provided the directory names were all unique) of the harddrive, then I could compile a test.java anywhere?
As a note: I have been able to get the test.java file to compile, by leaving out the import statement in the test.java file, and also leaving out the package statement for the sentence class, but I assume this is because the files are defaulted to the same package?

Hi Mary,
No, import isn't analogous to C++ namespace - Java package is closer to the namespace mark.
import is just a convenience for the programmer. You can go your whole Java career without ever writing an import statement if you wish. All that means is that you'll have to type out the fully-resolved class name every time you want to use a class that's in a package other than java.lang. Example:
// NOTE: No import statements
public class Family
   // NOTE: fully-resolved class names
   private java.util.List children = new java.util.ArrayList();
}If you use the import statement, you can save yourself from typing:
import java.util.ArrayList;
import java.util.List;
public class Family
   // NOTE: fully-resolved class names
   private List children = new ArrayList();
}import isn't the same as class loader. It does not bring in any source code at all.
import comes into play when you're compiling or running your code. Java will check to make sure that any "shorthand" class names you give it live in one of the packages you've imported. If it can't find a matching fully-resolved class name, it'll give you a message like "Symbol not found" or something like that.
I arrange Java source in a directory structure that matches the package structure in the .class files.
If I've got a Java source file like this:
package foo.bar;
public class Baz
   public static void main(String [] args)
        Baz baz = new Baz();
        System.out.println(baz);
   public String toString()
       return "I am a Baz";
}I'll store it in a directory structure like this:
root
+---classes
+---src
      +---foo
           +---bar
                +---Baz.javaWhen I compile, I go to root and compile by typing this:
javac -d classes foo/bar/*.javaI can run the code from root by typing:
java -classpath classes foo.bar.BazI hope this wasn't patronizing or beneath you. I don't mean to be insulting. - MOD

Import statement in .java files and .jsp files

Guys I have few mysteries about this import statement.
Please correct me if I am wrong.
1)Suppose if I have a folder c:\SourceFolder it has one.java and two.java files.If I compile one.java then one.class files is created in c:\ClassFolder .Now two.java uses one of the method of one.java,and without using import statement I am able to compile two.java, and two.class file is created in c:\ClassFolder.I assume that the path of one.class was taken from the CLASSPATH environment variable,hence I there was no need for import statement .........am i right ?
BUT... in My.jsp,which is in C:\JspFolder, if I want to use one.class,then I have to specifically import the class I want to use.That is i have to say
<%@page import="one"%>
and since the classpath is C:\ClassFolder ,it finds one.class in the C:\ClassFolder.(Note that My.class is created in a folder different from c:\ClassFolder )
But I am wondering why was there no need for me to import one.class in two.java.
(Note I am using JDeveloper and Apache server)
Please help.
In this case the pSo I am wondering in JSP why it doesn't take the class I am looking for from the classpath .
Help.

You have to understand Java scoping rules. In the 1st scenario with the two Java files I am guessing neither one of them begins with a package statement. This means that they belong to the default package. When you compile the compiler uses the classpath to resolve method calls looking in the default package since there was no import statement specified in two.java. JSP is a little different. Now I just read this here in these forums a couple of days ago. Since the classfiles generated from the JSP files are not in the CLASSPATH they are loaded by a different classloader. This is why you have to import all references to all classes in the default package.

Import statement question

what's the difference between
import java.util.Vector;
and
import java.util.*;
is there any difference in bytecode generated? or time takes to compile?
what's the best practice?

Yes there is a best practice, it's the one you mentioned. Use the more specific import statement. If you're only using one or two classes from a package, explicitly name them in the import statements. That way somebody else reading your code (which includes yourself, six months later) can immediately get a better understanding of your code.
If this rule is followed, and you see this as the first line of a source file:
import java.util.StringTokenizer;
then you know the StringTokenizer is being used. But if you saw this:
import java.util.*;
you wouldn't know which one is being used until you're deep in the code.
Knowing right away whether a class is tokening a string, versus say using collections, makes it a lot easier to read.
You should only use the whole-package include if you're importing a really big part of the package. For example:
import java.awt.*;
is probably OK because it's relatively unlikely a person will use only a couple classes from that package.

Confused about CLASSPATH and how java handles import statements...

Hello,
I must admit I don't get it. I read the articles about setting CLASSPATH etc. but I still wonder:
If you use an import statement, what does the compiler do? I.e. where does it look for the specified classes? I find it confusing because I see in different locations different .jar files:
C:\jdk1.3.1_03\lib\dt.jar
C:\jdk1.3.1_03\lib\htmlconvertor.jar
C:\jdk1.3.1_03\lib\tools.jar
and also
C:\jdk1.3.1_03\jre\lib\i18n.jar
C:\jdk1.3.1_03\jre\lib\rt.jar
C:\jdk1.3.1_03\jre\lib\jaws.jar
C:\jdk1.3.1_03\jre\lib\sunrassign.jar
Can someone explain me what the purpose is of these files?
And why do I have the same contents in
C:\Program Files\JavaSoft\JRE\1.3.1_03\lib
and in
C:\jdk1.3.1_03\jre\lib
Why is that?
Thanks for answering my questions!
-mike

Thanx for the answers, but I still wonder, everyone
here says I need to set the classpath, but I don't.Probably because your classes are already in the class path. The compiler/jvm also look for classes by themselves not just in jar files, when just a directory is supplied in the class path. And a period (".") is a valid directory.
Programs importing different classes compile with no
problem. So what's up with that?
Presumably you are referring to your own code - because they are in the class path.
Second, I still don't understand why the runtime needs
the .jar files. The runtime uses classes, like String, that have to come from somewhere.
This would also mean that end-users
need to set the classpath to the .jar files in their
JRE directory to be able to run programs that import
classes from these .jars. But this is not true, right?No it is true. The end-users will have to set the class path. There are variations on this which make it seem like no class path is set. For instance applets in a browser are java but the end-user does not need to set a class path. That is because the browser knows how to download classes/jars and how to set it up so it uses them. (Actually it uses a class loader, but that is probably more information that you need.)
Because if I make some nice classes myself and import
them, how can I expect my end-user to install these
classes and make a classpath for them?That would be between you and you end-user.
First installation is not part of java. For installation you will have to find something outside of java to accomplish the goal.
Additionally how the class path gets set is OS specific. Java does not deal with that. You will also have to find some way to deal with this (most likely part of the installation.)
There are also variations on this. For example the browser example I gave above. Or using the ext directory. Or creating an executable jar. Or simply setting the class path.
In my understanding it should only be needed in the JDK, not
in the JRE. True or am I mistaken?Mistaken. The class path is needed in the JRE as well. You will need to set it.

Using Import Statement

Hi,
I understand that in order to access the methods of a different class, I can "import" it. Here is my question though:
Where am I importing it from? I mean, surely if I am importing a class from e.g. the Java.util package, doesn't this package need to be on my computer somewhere?
And also, if I make a .jar file of my application for use on another computer and the files contain import statements, doesn't the other computer need to have these packages on their machine?
I know this seems like a silly question but it's bothering me!
GF

Yep, you can unzip them to see inside. The package name unzips into a directory structure and the Class name is a file. So java.util.HashMap will unzip into a directory java/util and have a file called HashMap.class in it.
You can usually download the source code for these classes also.

Pls help! How to put JSP import statement...

Hi, I just created a simple iView JSP that imports htmlb classes and now I'd like to import my own java classes onto it. For example, in my other projects, my JSP's have <%@ page import="project28.practice.contextClass" %> on top of the page. I currently have a file called practice.jar
If I want to put this import statement into my simple iView JSP and use it, what would I have to do/configure?, do I have to transform it into a .par file? Or can I transport the jar file to the portal? Any changes on NetWeaver?
I am new to this so any detailed help or suggestions are greatly appreciated!
Thanks again,
Baggett

Hi Detlev, thank you for your response! I'd like to include more details of my situation right now: I have 2 projects on NetWeaver:
Project#1: Java Web application Project. (jar files, WEB-INF, WEB-INF/web.xml, JSP's...)
Project#2: Portal Application Project. (JSPDynPage, sap plugins, PORTAL-INF/portalapp.xml, JSP)
I'd want my JSP file in Project#2 to call some classes from the jar files of Project#1.
From my understanding, to do this I need to make a .par file out of Project #1 and then upload the par file to my SAP EP6.0 so that my future JSP's can import classes from it. Am I correct?
I am confused right now as to how to really do this. On Netweaver, I am getting a Error when I try to do: File --> New --> Project --> Portal Application --> Create a Portal Application Project > I then enterProject Name: TestProject28, Project root folder: c:\TestProject\webapps\project1
--> "ERROR: Invalid project description, Reason:An error has occured while trying to create the project structure"
If possible can you please provide detailed instructions on how to configure or build a par file out of my java web application stated above?
Thank you so much for your time and help!

Newbie question : import statements

So, i'm a complete java newbie trying to make his first swing application, a basic calc. I download NetBeans 6.5, install it, and begin to code. I quickly learn about the Matisse GUI editor, find it very easy to use, and in a couple hours, the work is done and runs very fine.
But looking at my code, I realize I have forgotten all import statements (like import javax.swing, import java.awt.event ....), nevertheless the application runs fine. I suppose then that the Netbeans compiler automatically corrects my mistakes, but I want to do it right.
So, I write the import statements explicitly in my code and I get a warning message : "import unused". After that, I find out about the "fix import" tool in Netbeans, use it and all my import statements disappear. I guess i'm missing something here.
I thought import of swing classes were mandatory to write a swing application. I have NO import statement in my code, even if I'm using jFrames, jButtons, event handlers and the program works fine, why ?
Would I be able to compile this importless code in another environment (let's say Eclipse or even javac) ?
I'm using JDK 1.6 and Netbeans 6.5 with Windows XP.
TIA

Ok, thanks for the answers, and sorry for my misinterpretation of BigDaddyLoveHandles's first post. I understand now, the import statements are useful only if you don't want to write full class names, and the generated code uses full class names so no import needed.Please also understand BigDaddyLoveHandles's latest post. If you learn to code Swing with NetBeans' Matisse, then you will be learning Matisse, not Swing. When it comes time to try to tweak or upgrade your program, you will be lost. Better is to learn Swing from the ground up by going through the Sun Swing tutorials. Though having said that, if you are very new to the language, better still is to learn the fundamentals of Java first before embarking in the murky waters of GUI programming. Best of luck to you in your endeavors.

Please explain the IMPORT statement?

I have been searching for information on the import statement, but can't seem to locate it. I understand how to use import, but I would like to know, in detail, exactly what it does.
When I import, for example; "java.awt.*", I would expect this statement to import ALL of the classes define under "java.awt". However, I notice in the DiveLog class, that I must also import "java.awt.event.*". This is confusing to me.
Can someone either explain this for me, or point me to the imort documentation?

aye - what yawmark says. And also be aware that import doesn't really "import" any source (not the way #include does, if'n you're an old school C coder). It's just there to shorten typing. You can either type "java.io.IOException" a lot, or import java.io.IOException and get away with just typing "IOException". But you've just "imported" the namespace, not any kind of source.
Make sense?

Hi Nikita,
Welcome to Workshop!
The JWS classes used in Workshop are essentially Java classes with the
additional capability to understand the JWS metatags in the comments.
Hence you can use the import statements in the same manner as you use in a
normal Java class.
Please do let us know if you have any further queries.

Cannot resolve import statements

I recently decided to start messing around with some Java3d. I tried to get an example program to try to dissect but I can't even get past compilation. The main problem is the fact that the import statements cannot be resolved. I thought maybe I was using an outdated example program but upon further inspection of Oracle's own Java3d tutorials I saw the same import statements. I downloaded java3d 1.5.1 because I thought perhaps it wasn't included in the java core classes. This did not help me at all. So maybe it is a problem with the IDE (eclipse) not recognizing them. However, I have had no such success with Google thus far. I realize that this is more than likely a horribly simple mistake that anyone over a novice understanding of Java would be able to spot. But if anyone could help me figure out why I can't compile it would be much appreciated.
Regards,
Corey

Timeline Import Statements

I have a bunch of MovieClip Symbols in Library. They all need to import the same classes for timeline code. I don't want to add the import statements to every MovieClip's timeline. I can't add import statements to base-class & get access from MovieClip's timeline.
What do I do?

It sounds like Inheritance doesn't work like that. Imports added in the base-class ( super ) aren't available to the child class. I've tried it.
For example, importing TweenLite in the base-class, will not allow you to use TweenLite from the child-class or it's timeline. I completely understand this from the OOP perspective, but am hoping for some workaround that either bends the rule, or is another easy approach.
I thought addFrameScript might be a method that allows you to execute arbitrary code on any particular frame ( such as imports ), but it doesn't seem to work in that way. It seems more like a onFrame callback.

Filename in import statement

Hi srinivas bobbala,
Thank you for your response.But I think my quesition was not clear.My ques... is for suppose there is one datafile for importing like.. "datafile_21" Here my intention is it takes file from datafile_21 only but it appears in import statement like datafile_21<<curmon>>.
import database sample.sample data from data_file "c:\\ABC\datafile_21_AUG.txt" using server rules_file datafile on error abort;
In this it takes datafile from datafile_21.But it appears like datafile_21_AUG in import statement.This AUG coming from batch file.
Essmsh c:\\ABC\loadmxl.mxl %curmon%

No it is not possible.
I assume the data file "datafile_21" is first renamed to datafile_21_${CurrMth} in the batchscript.
After that this data file *datafile_21_${CurrMth}* is pointed in the import statement.
In the logs you will see this file as datafile_21_Aug.

Import Statement Different ways to refer ???

Dear Friends,
Can any one help me the difference between the usage of import statement....
1. using import statement
2. using the class directly
that is,
for example ;
1. import java.util.Date;
Date dt = new Date();
2. java.util.Date dt = new java.util.Date();
what's the difference between two reference of Date class...is there any meaning beyond this ?????
Regards,

what's the difference between two reference of Date
class...is there any meaning beyond this ?????there is no difference once the code is compiled - the compiler resolves single class names to their fully-qualified names (ie with the package prefix) and that appears in the .class file constant pool
before compilation then my opinion is that having all the imports at the top of the file is good practice because you can see what is being used easily

IMPORT statement understand
