Simple question Of variable scope

If u do not define any scope for a variable waht is the default scope for the variable.
is it private Public or some thing in between the two ????

The default access has no keyword, but it is commonly referred to as "friendly"
It means that all the other classes in the current package have access to the friendly member, but to all the classes outside of this package the member appears to be private.

Question about variable scope

Suppose theres a class that mixes colors.
It has an constructor and two methods:
public class ColorMix {
//This is just an example but I've tried this and colors
mix and show up correctly.
public ColorMix() {
cmColor = MixColors();
} //e_constr
private void mixColors() {
//do something
Color1 = createColors();
Color2 = createColors();
//etc
private Color createColors() {
//create some color-values
//r, g and b ...
Color anColor = new Color (r, g, b) //finally create color
return anColor; //and return that color
public Color cmColor;
} // e_class_ColorMix
My question is: Howcome and how the variable
'anColor' is referred from the createColors-method to
the mixColors-method?!? I thought that anColor would
be out of scope, since its created in the createColors
I've understood it would be erased once createColors
is done with?!?
Or did MixColors make it to the 'anColor' before garbage
collector?
Thanks,
Jani

I think you are mixing up variables and objects. A variable (like "anColor" in your example) is not the same as an object. A variable is just a reference to an object that exists somewhere in memory.
Objects are eligible for garbage collection if the running program does not hold any reference to the object anymore.
Your createColors() method creates a new object of type Color and stores a reference to it in the variable anColor. Then it returns the value of the variable (which is the reference to the Color object) to the calling method: mixColors. There you have another variable (Color1) which will hold the reference to the object.
So the variable anColor goes out of scope at the end of method createColors(), but the program still has a reference to the object, stored in variable Color1.
The object is still referenced by the program and will therefore not be garbage collected.
I'd suggest you read the Java Tutorial: http://java.sun.com/docs/books/tutorial/java/index.html

1 simple question about variable

I want to make a query. when I open this query, I want to use a variable, that when I open it, the weeknumber automatically is filled in. How can i do that?Does SAP deliverd this already?(SAP-exit)How can I make one?Do I have to use customer exit?

Hi K,
For achieving this you have to use a Customer Exit Variable with Default Value. Do you want to fill it with the same week every time or is it current week. If it is the same week everytime then default value will help.
But if you want to use Current Week then you SAP Exit Variable "Current Calander Week - 0CWEEK". This variable denotes the current calendar week in format YYYYWW.
Hope this helps.

A very very very simple question

Hi guys,
I have a very simple question and standard but I cant find anywhere...
I have two dateTime variables, i need to calculate difference between this dates in days, thats it.
I tried all functions and tried without success a Java Embed task but I couldnt retrieve this objects as java.util.Date so I couldnt calculate exactly the difference in days like this pure java code:
(dataVencimento.getTime() - dataReferencia.getTime()) / 86400000L)
can you help me this?

Hi Jose
Just see if these alternate approaches works. I know there may be lot like this and you may be lucky to find out simple out of box solution itself. If you want to solve this issue and move ahead, gives these approaches a shot.
1. Create a very simple standalone WebService that takes 2 input date elements (can be of Date type or String type. If string type, convert to date in your java code). Create a simple operation like getDaysBetween(firstDate, secondDate). In the generated webservice impl class, use the java code apis (refer earlier link for usage), and get the difference. Return this value. NOW, invoke this WebService in your BPEL Process, and pass your 2 inputs (if the bpel payload elemetns are date object or string objects of date), and get output, and then use this output in your continuing bpel process.
2. This approach, I did a long back. When we insert any expression using XPath, in that editor window on bottom right side, we see many categories and for each category we see list of functions we can use, like for String, we can use concat etc. I vaguely remember reading somewhere, that we can add our own custom functions also in this section. So explore this direction and see if you can add your own function and then use that fucntion with your 2 input dates.
I have not given solution to your problem, but may be these directions can help you move ahead. Or something along these lines.

Simple Question... general syntax

I am clearly new to Oracle. Simple question though. I have a Procedure that runs a fairly involved query. The procedure is called and parameters are passed into it. While I am testing, I just want to DECLARE my variables so it will run properly. I am trying the following:
DECLARE
Var1 Varchar(2) := TO_CHAR('11/01/2012', 'MM/DD/YYYY')
Var2 Varchar(2) := TO_CHAR('11/30/2012', 'MM/DD/YYYY')
BEGIN
Select....;
END;
My query runs fine if I cut it out and enter values for all the variables. Is this the proper syntax to stuff a value for testing? I get an error saying the Select statement needs an INTO statement when I do it this way.
Thanks,
Dave

As other have pointed out, you should be sure that you require a Varchar variable and not a Date.
If you need varchar, then you have to specify proper width to it. And syntactically correct; Each PL/SQL statement ends with a Semi-colon, that includes variable declarations as well.
It should be the following way:
DECLARE
Var1 Varchar(10) := '11/01/2012';
Var2 Varchar(10) := '11/30/2012';Width of VARCHAR should be specified in BYTES/CHAR(s); the above example is for width in Bytes assuming Single Byte Character set. Also as SB pointed out, you need to read the concepts guide for PL/SQL to understand it and then practice it.
Happy learning.

A simple question about performance!

Hi! I have a simple question about performance. Suppouse that you have a servlet or a class with DB access, and you need to use a value several times in that page. What is best, to assign the value from say, a resultset or a request.getParameter() to a variable or to call the resultset or the request every time you need to retrieve that value? Which option uses less memory, which is faster, etc.?
Hoping the best fou u
Raul

If you need more values from a db, the best is to open some connections (connection pool) and use the for accessing the db.
To get the data only once, open the connection, get the data, store the data whereever you want: variable (class), hidden control (if you want to send from one page to another by request) and close the connection as quicky as possible.
The advantage of the first method is that the most time consuming activity (connections opening) is done only once.

Javascript discussion: Variable scopes and functions

Hi,
I'm wondering how people proceed regarding variable scope, and calling
functions and things. For instance, it's finally sunk in that almost
always a variable should be declared with var to keep it local.
But along similar lines, how should one deal with functions? That is,
should every function be completely self contained -- i.e. must any
variables outside the scope of the function be passed to the function,
and the function may not alter any variables but those that are local to
it? Or is that not necessary to be so strict?
Functions also seem to be limited in that they can only return a single
variable. But what if I want to create a function that alters a bunch of
variables?
So I guess that's two questions:
(1) Should all functions be self-contained?
(2) What if the function needs to return a whole bunch of variables?
Thanks,
Ariel

Ariel:
(Incidentally, I couldn't find any way of marking answers correct when I visited the web forums a few days ago, so I gave up.)
It's there...as long as you're logged in at least, and are the poster of the thread.
What I want is to write code that I can easily come back to a few months later
and make changes/add features -- so it's only me that sees the code, but
after long intervals it can almost be as though someone else has written
it! So I was wondering if I would be doing myself a favour by being more
strict about make functions independent etc. Also, I was noticing that
in the sample scripts that accompany InDesign (written by Olav Kvern?)
the functions seem always to require all variables to be passed to it.
Where it is not impractical to do so, you should make functions independent and reusable. But there are plenty of cases where it is impractical, or at least very annoying to do so.
The sample scripts for InDesign are written to be in parallel between three different languages, and have a certain lowest-common-denominator effect. They also make use of some practices I would consider Not Very Good. I would not recommend them as an example for how to learn to write a large Javascript project.
I'm not 100% sure what you mean by persistent session. Most of my
scripts are run once and then quit. However, some do create a modeless
dialog (ie where you can interface with the UI while running it), which
is the only time I need to use #targetengine.
Any script that specifies a #targetengine other than "main" is in a persistent session. It means that variables (and functions) will persist from script invokation to invokation. If you have two scripts that run in #targetengine session, for instance, because of their user interfaces, they can have conficting global variables. (Some people will suggest you should give each script its own #targetengine. I am not convinced this is a good idea, but my reasons against it are mostly speculation about performance and memory issues, which are things I will later tell you to not worry about.)
But I think you've answered one of my questions when you say that the
thing to avoid is the "v1" scope. Although I don't really see what the
problem is in the context of InDesign scripting (unless someone else is
going to using your script as function in one of theirs). Probably in
Web design it's more of an issue, because a web page could be running
several scripts at the same time?
It's more of an issue in web browsers, certainly (which I have ~no experience writing complex Javascript for, by the way), but it matters in ID, too. See above. It also complicates code reuse across projects.
Regarding functions altering variables: for example, I have a catalog
script. myMasterPage is a variable that keeps track of which masterpage
is being used. A function addPage() will add a page, but will need to
update myMasterPage because many other functions in the script refer to
that. However, addPage() also needs to update the total page count
variable, the database-line-number-index-variable and several others,
which are all used in most other functions. It seems laborious and
unnecessary to pass them all to each function, then have the function
alter them and return an array that would then need to be deciphered and
applied back to the main variables. So in such a case I let the function
alter these "global" (though not v1) variables. You're saying that's okay.
Yes, that is OK. It's not a good idea to call that scope "global," though, since you'll promote confusion. You could call it...outer function scope, maybe? Not sure; that assumes addPage() is nested within some other function whose scope is containing myMasterPage.
It is definitely true that you should not individually pass them to the function and return them as an array and reassign them to the outer function's variables.
I think it is OK for addPage() to change them, yes.
Another approach would be something like:
(function() {
var MPstate = {
    totalPages: 0,
    dbline: -1
function addPage(state) {
    state.totalPages++;
    state.dbline=0;
    return state;
MPstate = addPage(MPstate);
I don't think this is a particularly good approach, though. It is clunky and also doesn't permit an easy way for addPage() to return success or failure.
Of course it could instead do something like:
    return { success: true, state: state };
var returnVal = addPage(MPstate);
if (returnVal.success) { MPstate = returnVal.state; }
but that's not very comforting either. Letting addPage() access it's parent functions variables works much much better, as you surmised.
However, the down-side is that intuitively I feel this makes the script
more "messy" -- less legible and professional. (On the other hand, I
recall reading that passing a lot of variables to functions comes with a
performance penalty.)
I think that as long as you sufficiently clearly comment your code it is fine.
Remember this sort of thing is part-and-parcel for a language that has classes and method functions inside those classes (e.g. Java, Python, ActionScript3, C++, etc.). It's totally reasonable for a class to define a bunch of variables that are scoped to that class and then implement a bunch of methods to modify those class variables. You should not sweat it.
Passing lots of variables to functions does not incur any meaningful performance penalty at the level you should be worrying about. Premature optimization is almost always a bad idea. On the other hand, you should avoid doing so for a different reason -- it is hard to read and confusing to remember when the number of arguments to something is more than three or so. For instance, compare:
addPage("iv", 3, "The rain in spain", 4, loremIpsumText);
addPage({ name: "iv", insertAfter: 3, headingText: "The rain in spain",
numberColumns: 4, bodyText: loremIpsumText});
The latter is more verbose, but immensely more readable. And the order of parameters no longer matters.
You should, in general, use Objects in this way when the number of parameters exceeds about three.
I knew a function could return an array. I'll have to read up on it
returing an object. (I mean, I guess I intuitively knew that too -- I'm
sure I've had functions return textFrames or what-have-you),
Remember that in Javascript, when we say Object we mean something like an associative array or dictionary in other languages. An arbitrary set of name/value pairs. This is confusing because it also means other kinds of objects, like DOM objects (textFrames, etc.), which are technically Javascript Objects too, because everything inherits from Object.prototype. But...that's not what I mean.
So yes, read up on Objects. They are incredibly handy.

A simple question on random number generation?

Hi,
This is a rather simple question and shows my newbieness quite blatantly!
I'm trying to generate a random number in a part of a test I have.
So, I have a little method which looks like this:
public int getRandomNumber(int number){
        Random random = new Random(number);
        return random.nextInt(number);
    }And in my code I do int random = getRandomNumber(blah)...where blah is always the same number.
My problem is it always returns the same number. What am I missing here. I was under the impression that nextint(int n) was supposed to generate the number randomly!! Obviously I'm doing something wrong or not using the correct thing. Someone please point out my stupidity and point me in the right direction? Ta

I think the idea is that Random will generate the same pseudo-random sequence over and over if you don't supply a seed value. (The better to debug with, my dear.) When you're ready to put an app into production, the seed value should be the current system time in milliseconds to guarantee a new sequence with each run.
Do indeed move Random outside the loop. Think of it like a number factory - instantiate it once and let it pump out the random values for you as needed.

A simple Question about % in CR Chart!

Hi, I have another simple question.
When i use SQL to storage data and wanna Crystal Report to display the data in chart using %
which data type should i use?
float or string?
and I found when i use 0.12 as 12% in database , It could not display in Crystal Report line chart normally.
What should I do??
Please Help!!!
Thank you VERY MUCH!!!

If you have the datatype as string from your database then try adding the string field as a summary field in chart and select maximum instead of count and if you have them in number format then you can directly select the percentage in chart.

Simple question: I want to use iCloud as a back up disk for my documents folder. How can I do this? If I cannot do this, why am I paying for access to "the cloud?"

Simple question: I want to use iCloud as a back up disk for my documents folder. How can I do this? If I cannot do this, why am I paying for access to "the cloud?"

iCloud does not provide general file storage or backup, so you cannot back up your Documents folder using it. You will need to find a third-party alternative - this page examines some options (some are free):

iCloud at basic level, with 5GB is storage, is free: you only pay anything if you want to increase the storage space.

Simple question about JAVA path

Hi. I have a simple question , but I spent several hours trying to find an answer.
How do I know the location of the java executable which is used by Concurrent Manager.
I already know that running which java under application user will not give me the correct answer

Maybe you can try like this:
     public String getPath(){
          Class cls=getClass();
          String className=cls.getName();
          String packageName=cls.getPackage().getName();
          System.out.println(className);
          System.out.println(packageName);
          String newClassName=className.replaceAll("\\.", "/");
          String resouceName=newClassName+".class";
          System.out.println(resouceName);
          URL url;
          url=cls.getClassLoader().getResource(resouceName);
          String path="";
          path=url.getFile();
          return path;
     }

Load Balancing Directory Servers with Access Manager - Simple questions

Hi.
We are in the process of configuring 2 Access Manager instances (servers) accessing the same logical LDAP repository (comprising physically of two Directory Servers working together with Multi-Master Replication configured and tested) For doing this, we are following guide number 819-6258.
The guide uses BigIP load balancer for load balancing the directory servers. However, we intend to use Directory Proxy Server. Since we faced some (unresolved) issues last time that we used DPS, there are some simple questions that I would be very grateful to have answers to:
1. The guide, in section 3.2.10 (To configure Access Manager 1 with the Directory Server load balancer), talks about making changes at 4 places, and replacing the existing entry (hostname and port) with the load balancer's hostname and port (assuming that the load balancer has already been configured). It says that changes need not be made on Access Manager 2 since the LDAPs are in replication, and hence changes will be replicated at all places. However, the guide also states that changes have to be made in two files, namely AMConfig.properties, and the serverconfig.xml file. But these changes will not be reflected on Access Manager 2, since these files are local on each machine.
Question 1. Do changes have to be made in AMConfig.properties and serverconfig.xml files on the other machine hosting Access Manager 2?
Question 2: What is the purpose of putting these values here? Specifically, what is achieved by specifying the Directory server host and port in AMConfig.properties, as well as in serverconfig.xml?
Question 3. In the HTTP console, there is the option of specifying multiple primary LDAP servers, as well as multiple secondary LDAP servers. What is the purpose of these? Are secondary servers attempted when none of the list in the primary list are accessible? Also, if there are multiple entries in the primary server list, are they accessed in a round robin fashion (hereby providing rudimentary load balancing), or are other servers accessed only when the one mentioned first is not reachable etc.?
2. Since I do not have a load balancer setup yet, I tried the following deviation to the above, which, according to me, should have worked. If viewed in the HTTP console, LDAP / Membership / MSISDN and Policy configuration all pointed to the DS on host 1. When I changed all these to point to the directory server on host 2 (and made AMConfig.properties and serverconfig.xml on host 1 point to DS of host 2 as well), things should have worked fine, but apparently Access manager 1 could not be started. Error from Webserver:

In effect, AM on 1 did not start. On rolling back the changes, things again worked like previously.
Will be really grateful for any help / insight / experience on dealing with the above.
Thanks!

Update to the above, incase anyone is reading:
We setup a similar setup in Windows, and it worked. Here is a detailed account of what was done:
1. Host 1: Start installer, install automatically, chose Directory server, Directory Administration server, Directory Proxy server, Web server, Access Manager.
All installed, and worked fine. (AMConfig.properties, serverconfig.xml, and the info in LDAP service, all pointed to HOST1:389)
2. Host 2: Start installer, install automatically, chose Directory server, Directory Administration server, Directory Proxy server, Web server, Access Manager.
All installed, and worked fine. (AMConfig.properties, serverconfig.xml, and the info in LDAP service, all pointed to HOST2:389)
3. Host 1: Started replication. Set to Master
4. Host 2: Started replication. Set to Master
5. Host 1: Setup replication agreement to Host 2
6. Host 2: Setup replication agreement to Host 1
7. Initiated the remote replica from Host 1 ----> Host 2
Note that since default installation uses abc.....xyz as the encryption key, setting this to same was not an issue.
9. Started webserver for Host 1 and logged into AM as amadmin.
10. Added Host 2 FQDN in DNS Aliases / Realms
11. Added http://HOST2_FQDN:80 in the Platform server (instance) list.
12. Started Host 2 webserver. Logged in AM on Host 2, things worked fine.
At this stage, note the following:
a) Host 1:
AMConfig.properties file has
com.iplanet.am.directory.host=host1_FQDN
and
com.iplanet.am.directory.port=389
serverconfig.xml has:
<Server name="Server1" host="host1_FQDN" port="389" type="SIMPLE" />
b) Host 2:
AMConfig.properties file has
com.iplanet.am.directory.host=host2_FQDN
and
com.iplanet.am.directory.port=389
serverconfig.xml has:
<Server name="Server1" host="host2_FQDN" port="389" type="SIMPLE" />
c) If one logs into AM, and checks LDAP servers for LDAP / Policy Configuration / Membership etc services, they all contain Host2_FQDN:389 (which makes sense, since replica 2 was initialized from 1)
Returning back to the configuations:
13. On Host 1, login into the Admin server console of the Directory server. Navigate to the DPS, and confgure the following:
a) Network Group
b) LDAP servers
c) Load Balancing
d) Change Group
e) Action on-bind
f) Allow all actions (permit modification / deletion etc.).
g) any other configuations required - Am willing to give detailed steps if someone needs them to help me / themselves! :)
So now, we have DPS configured and running on Host1:489, and distributing load to DS1 and DS2 on a 50:50 basis.
14. Now, log into AM on Host 1, and instead of Host1_fqdn:389 (for DS) in the following places, specify Host1_fqdn:489 (for the DPS)--
LDAP Authentication
MSISDN server
Membership Service
Policy configuation.
Verified that this propagated to the Policy Configuration service and the LDAP authentication service that are already registered with the default organization.
15. Log out of AM. Following the documentation, modify directory.host and directory.port in AMConfig.properties to point to Host 1_FQDN and 489 respectively. Make this change in AMConfig.properties of both Host 1 as well as 2.
16. Edit serverconfig.xml on both hosts, and instead of they pointing to their local directory servers, point both to host1_FQDN:489
17. When you start the webserver, it will refuse to start. Will spew errors such as:

[https-host1_FQDN]: startup: server started successfully
Success!
The server https-host1_FQDN has started up.
The server infact, didn't start up (nothing even listening on 58080).
However, if AMConfig.properties is left as it originally was, and only serverconfig.xml files were changed as mentioned above, web servers started fine, and things worked all okay. (Alright, except for some glitches when viewed in /amconsole. If /amserver/console is accessed, all is good. Can this mean that all is still not well? I am not sure).
So far so good. Now comes the sad part. When the same is done on Solaris 9, things dont work. You continue to get the above error, OR the following error, and the web server will refuse to start:
Differences in Solaris and Windows are as follows:
1. Windows hosts have 1 IP and hostname. Solaris hosts have 3 IPs and hostnames (for DS, DPS, and webserver).
No other difference from an architectural perspective.
Any help / insight on why the above is not working (and why the hell does the documentation seem so sketchy / insecure / incorrect).
Thanks a bunch!
