Problem with out variable

I have been working for months with java and all of a sudden today when i was compiling a program i got an error stating that the variable out can't be.
To confirm my suspicion that somrhtings wrong i wrote this program and tested it
class Example
public static void main(String args[])
System.out.println("This is my first program");
}And i get this error when i compile
Cannot find symbol
variable out
All this time the JRE was ok and now this unexpected problem.Whats happening?It works if I import java.lang.System and run the program.I have been working for months and this is the first time.Is it because of some virus or something.Should i reinstall the JDK.I thought of asking at the forum before i could try reinstalling and checking it out again.

.. Where do you get this error? Eclipse has a bug
which is related to this. Sometimes I have to remove
the JRE from installed JREs in Eclipse, and then just
add it again, and then everything works.
KajI don't use an IDE.I use the command prompt.I get the error at the command prompt.
My computer has two OS both XP.I jdk 1.5 installed on both these OS.I run the jdk on the first jdk which is on the active partition and when it stopped working on this one i immediately restarted the pc and started the other xp where i have installed jdk 1.5 too.But even there it's the same case.
But if any environment variables or registry contents have changed thats local to the first xp but how will it effect the second xp.Is it because of any virus
Please note i will be going out and will get back to the thread in around 2 hours.Thanks a lot of the response.

Problem with String variable

I am new to Java Programming.
I have a line of code that works and does what is supposed to.
faceData.getProfile("Lisa").removeFriend("Curtis");
If I assign the strings to variables such as-
String name = "Lisa";
String fName = "Curtis";
and then plug those into the same line of code, it does not work
faceData.getProfile(name).removeFriend(fName);
What could be causing the problem?
I even added some lines to print out what is stored in the variables to verify that they are what they should be, but for some reason the variables do not work while putting the strings in quotes does. Any ideas?

I guarantee that something about your assertions are incorrect. Those variables are either not equal to the values you claim, or something else is going on. But it's not a problem with string variables versus string constants.
Edit: My best guess in lack of a real example from you, is that the strings in question have non-printable characters in them, such as trailing spaces or line feeds.

Problems with /tmp variable

Hi,
I'm writing a shell script and I seem to be having problems with a variable that is creates a directory in the /tmp directory. Essentially, there are several points where various parts of the script call out information that gets exported to that directory. My script is failing upon creation of this directory, is there any specific permissions on the /tmp directory in mac that would need to be set before something like this occurred?
Thanks!

My script is failing upon creation of this directory
Maybe you could post your code, that way we can see how you're trying to create the directory and may be able to spot the problem. As it is we're working blind, and that's not easy.

Problem with formula variable

Hi,
here is some idea.. here i have taken expample dates 1)notification creation date and 2) notification completion.
1st:in the query designer at key figure coloumn create
one local formula.in that local formula create formula
variable with replacement path.in that take reference character
notification completion.in the next tab take replace ment
as key.in the last tab select "date".
2nd: do the same thing for the notification creation date.
3 rd : create 3 rd local formula and do the substraction
for the first 2 local formulas.
4th:create codition on the difference which u have find with
on that condition u can create one user entry varibale.
5th:while u defining the query put these 2 dates,i,e
notification completion, notification creation date in the character block.
If not system will ignore the formula variable which u created in
above steps.
Hope this wil help u.
regards....KP

HT5137 I made a purchase with my debit card on The Simpson Tapped out game, And now my game won't open. It just kicks me out every time I click on it. How do I fix this problem with out deleting my app?

I made a purchase with my debit card on The Simpson Tapped out game, And now my game won't open. It just kicks me out every time I click on it. How do I fix this problem with out deleting my app?

Personally, I would never use a debit card online, for security reasons. If your card gets hacked its your money that is stolen. At least with a credit card it is the card providers money that is stolen.
Anyway, I would delete the app and re-install. If you paid for the app in the first place you will be able to re-install free of charge. Also, the app should allow the in-app purchase to happen again as it should recognise that you have already purchased it previously.
Finally, it might be that the 3G doesnt have as much ram as more recent models of iphone and you may have applications running in the background that are preventing the app to function with the in-app purchase unless you shut down any apps eating all you memory that are running in the background. Shut-down these apps (and the simpson tap out app) by exiting to your home screen and double-tapping the home button to show what apps are running in the background. press and hold any of the open apps until it starts shaking. close all the apps down. exit then re-launch the app.
good luck.

How can I execute a Procedure with OUT variable is %ROWTYPE on SQL Prompt

Hi,
I have a procedure with OUT variable is %ROWTYPE
How can I execute the following procedure on SQL prompt.
(without creating anonymous block)
CREATE OR REPLACE PROCEDURE zz_sp_EMP(VEMPNO IN EMP.EMPNO%TYPE,
V_REC IN OUT EMP%ROWTYPE)
AS
BEGIN
SELECT * INTO V_REC FROM EMP WHERE EMPNO = VEMPNO;
END;
Thanks & Regards,
Naresh

as previous posters said: it's not possible to do this without declaring a variable in the anonymous block.
With anonymous block it would look like this (had to change it a bit, since i'm using hr-schema on oracle XE):
declare
l_rec EMPLOYEES%ROWTYPE;
begin
zz_sp_EMP(VEMPNO => 100, V_REC => l_rec);
DBMS_OUTPUT.PUT_LINE ( 'first_name = ' || l_rec.first_name );
DBMS_OUTPUT.PUT_LINE ( 'last_name = ' || l_rec.last_name );
end;
first_name = Steven
last_name = King

TPC 2012 - Problems with shared variable

Hi,
I tried to program simmilar thing to this one http://zone.ni.com/devzone/cda/tut/p/id/5548 on TPC 2012. But it doesn't work.I can see that both programs on my laptop and TPC are working(I've added an additional counter with display), but I cannot see any effect on TPC when I change the value of shared variable on my laptop. I use LabView 8.6 with Touch Panel Module. My question is what are the exact steps to run such application on TPC2012? Are they the same as for TPC 2006?
I've noticed following issues:
1.I cannot deploy the program from Project Manager(there is an information that maybe TPC Service is not started. - I've found such information about TPC Service http://digital.ni.com/public.nsf/allkb/DE177828D27A14A48625734E00768B66 but in fact I cannot find Start » All Programs»National Instruments » NI TPC Service » NI TPC Service Manager 1.0 Does it mean, that the TPC Service is not installed and the programm with shared varibles won't be working or can I start it somehow in another way? Do I need to have TPC service installed on TPC2012?
Until now, I've built the project and sent it through FTP to TPC(the folder was /TEMP) and then started it.
2.Ping works OK
Thank you in advance for any hints how to solve this problem.

Problem with application-variables - CFLOCK?

Hi,
i have a problem with my application. It is a multi-user
application with 100 parallel-users and CFMX 7.
The problem wich occures is with application variables. These
are mainly structs wich get filled onApplicationStart(). The
problem is, that the variables suddenly disappear, they are empty.
I have read about CFLock and found out, that it is necesseary
to use cflock. And i found out, that onApplicationStart does
correct locking automatically. That is where i do not understand
the problem. The variables get intialized correctly and in further
they only get read-access. Why can they be corrupted?
My other question about that is, wheather i need cflock for
all Read-Access to Application and Session-Variables, even if there
happens no writing to the variables?
Best Regards,
Andreas

> ?The element of position 2, of dimension 2, of an array
object used as part of

> The array is in this case the struct.
Well, OK, that could be a problem. Arrays are not structs:
they are two
different things, are not interchangeable, and have
completely different
sets of functions to utilise them. You cannot treat a struct
as an array.
If CF is claiming your "struct" is an array, then it actually
*is* an
array, not a struct.
What's the line of code which is generating that error?
I suppose one could get this error if you have an array of
structs thus:
myArray
.key1
myArray.key2
(etc)
and you're trying to reference it with a numeric key rather
than by key
name, eg:
myArray
[n]
When n is an integer value, rather than a string (which
corresponds to the
name of the key).

So does this not happen in your dev / testing environment?

I would ***-u-me that the application one would be called
before the
request one. It's pretty easy for you to test this though, I
should think?
(Sorry: for reasons beyond the scope of this conversation,
we're still
forced to use Application.cfm in our software, so I've only a
passing
knowledge of how Application.cfc works).

One thing I will say here is that I really think you should
be separating
your processing from your display. A function should do
processing. it
should pass that processing back to a CFM template which
should handle
whatever needs to be displayed on the browser. Although
that's nowt to do
with your current issue.

Problem with hierarchy variable while displaying query in Portal

Hi,
I came up with an problem with a query in the portal. The problem is :
I have one query which is displayed in the portal. The Query has hierarchial selection criteria. I am executing the same query using analyzer. Its taking the variable from the selection and displaying it on the analyzer. I have used the option to " display the query on web " from the BEX query designer. From there its opening and displaying the results with the given selection criteria.
Where as when i open the query seperately in portal, its not displaying the results.
I came to know from one of my colleague that the porblem is with the Web item and the hierarchial variable declared in WAD was different from the variable declared in the BEX Query designer.
I never Worked with WAD. I tried finding out the variable definition. But i was unable to find out where the Hierarchial variable was defined.
Please help me out regarding the same.

The problem is sovled.

Problem with out of memory and reservation of memory

Hi,
we are running a very simple java program on HP-UX that do some text substitution - replacing special characters with other characters.
The files that are converted are sometimes very large, and now we have come to a point where the java server doing the work crashes with "Out of memory" message. (no stack) when it process one single 500MB large file.
I have encountered this error before(with smaller files) and then I have made the maximum Heap larger, but now when I try to set it to 4000M
i get the message:
"Error occurred during initialization of VM
Could not reserve enough space for old generation heap"
When it crash with this message, my settings are:
-XX:NewSize=500m -XX:MaxNewSize=1000m -XX:SurvivorRatio=
8 -Xms1000m -Xmx4000m
If I run with Xmx3000m instead the java program starts but I get Out of memory error like:
java.lang.OutOfMemoryError
<<no stack trace available>>
The GC log file created when it crashes looks like:

Can anyone please suggest what to do proceed troubleshooting or to change some settings? I'm not into this Java really so I really need some help.
Usually the java program handles thousands of smaller files (around 500 KB - 1 MB sized files).
Thanks!

You have a one to one mapping? Where one character is replaced with another?
And all you do is read the file, replace and then write?
Then there is no reason to have the entire file in memory.
Other than that you need to determine if the VM (which is not a Sun VM) has an upper memory bound. That would be the limit that the VM will not go beyond regardless of memory in the system.
We have 132GB of physical memory and a lot of not used Swap spaceOne would wonder why you have swap space at all.

Having problem with setting variable on a textfield

I'm using createTextField to create a textfield. I have also created a input textfield with a variable called textline1 (I don't create the inputfield with as).
I want to display the letters in the created textfiled that I'm typing in the input field. So this in my AS coed:
_root.createTextField("text1",1,100,100,300,100);
text1.variable = textline1;
format1 = new TextFormat();
format1.color = 0xff0000;
format1.size = 50;
format1.bullet = false;
text1.setTextFormat(format1);
but it doesn't work. So anyone see the problem?
(sorry for bad english)

i think you're going to have more problems if you continue using textfield variables. you should not use them. just use the text property of the textfield to reference its contents.
but, if you want to continue, use:
var tl:MovieClip=this;
fontsize=20;
myInputText_txt.onChanged = function(text1:TextField) {
_root.myText_mc.createTextField("text_txt",1,100,100, 100,100);
_root.myText_mc.text_txt.variable = tl["text2"];
text2=text1.text;
format1 = new TextFormat();
format1.color = 0xff0000;
format1.size = fontsize;
format1.bullet = false;
text_txt.setTextFormat(format1);
p.s. please mark this thread as answered.
