Why packages ??/

Why packages are used in Java and How to create a package in java???
i tried that by the below program
package A;
class new1 {
int a=10;
import package A.*;
class new 2{
new1= new aa;
System.out.println("num" +aa.a);
but it wont work
please help me

but it wont work hmm..maybe you should starts with a Hello World example..then work your way up..don't worry about package until you get the basic's basic down
it seem that you don't know how to instantiate a new instance.
it also seem like you don't know what a class is...what's allows and what's not allow...

Why Package Specification only in INVALID State

Hi All,
Why Package spec is going to invalid state when I change a Procedure which is called in Package body
and why package body is still in VALID state. Can some one please clarify my doubt.

May be only specification got errors and not the package.
May be the constants / variables declared in package specification has wrong reference
like var1 tab1.col1%type which column doesnexists....
OR
V number(1) :=10;
or
improper closing / ending of a procedure..

Packages are NOT transferring to new DP after adding it to a DP group - WHY!!!?

I am in the midst of trying to put together a Windows 8.1 DP and when I check the Distmgr.log, everything looks fine. Then when I add it to a DP group that my primary DP is a member of for the simple purpose of having those packages transferred over to the
new DP, I don't see any packages at all under the Content tab of the DP properties for the new Windows 8.1 DP with the exception of the Configuration Manager Client Package. Also, I created an AD group and named it SCCM Site Servers and I added my Site Server
to that and then added that group to the local admins group on the Windows 8.1 DP.
I need some help in determining why packages are not getting transferred, please HELP!
Here is what I am referring to:
When I check the pkgxfermgr.log, I see the following errors:

Thanks for the response, Jeff, I appreciate it.
Yes sir, that is what I stated initially up above in the posting:
Also, I created an AD group and named it SCCM Site Servers and I added my Site Server to that and then added that group to the local admins group on the Windows 8.1 DP.
Any other ideas what could be causing this?
I have never seen this before, obviously, so I am a tad stumped.
Thanks for your help

SSIS packages are failing after upgrade to SQL server 2014

Hi,
I have some SSIS packages running on SQL server 2012 .
After I upgraded to SQL server to 2014 from 2012 , the SSIS jobs are failing on the SQL agent.
And i can see its related to Data source connectivity to the SQL agent. I hope it not able to identify the connection manager in SQL agent. And connection adapter is not upgraded.
I read some articles about this and they say it not able to connect to SQL server agent job.
And, I can see that the package is running if i run manually using SQL 2012 run time.
Why its not running on SQL 2014 ?
did i miss anything while upgrading SQL server 2014 ?
Please give me some suggestions to solve this issue.
And is there any way i can change the SQL server agent 2014 to adapt this and run ?
Below is the error :
The Package filed to load due to error 0XC00100014 " One or more error occurres. There should be more specific errors preceding this one that expalins the details of the erroes. This message is used as a return value from functions that encounter
errors.: This occures when CPackage::LoadFormXML fails.
Regards,
Vinodh Selvaraj.

I think you have typed this error message by yourself.
Anyway, as it says there should be more error preceeding to this. Do you have any other errors which describles the exact issue stating at what task it fails?
If not, then there are various reasons behind this issue. 3rd party connection manager such as Oracle Attunity or it may be 32/64 bit issue.
You may try executing package in 32 bit mode from SQL Agent Job.

Package manager - question?

Hello folks,
I wish to know why Package manager in openSolaris is so
slow application. I know that it is written in Python, but
I still do not understand why somebody did not offer some
patch for that application. I will help honestly in programming
if you need coders.
Uros

Please send your question to [email protected] That is the best place for discussion OpenSolaris packaging tools such as packagemanager. This forum is better for Solaris installation issues (from Solaris 10 and SXCE, for example).

Pan Newsreader AUR Packages Confusion...

Hi,
not sure of this is the right group for this, but i just built a new Arch box and was installing my standard newsreader, Pan (v.0135) from files in the AUR, a process I've completed successfully a couple of times on other machines. Odd thing was, the version I installed kept segfaulting when I tried to delete article headers, a basic app function. I tried recompiling, checked the dependencies individually, etc., but nothing worked.
Then, I carefully scanned the AUR package list again and noticed that the package I had compiled, "pan-git," was not the only AUR package listed for Pan. I uninstalled pan-git then built and installed the correct pan-gtk3, which also gave me a functioning Pan v. 0.135, but this one doesn't constantly segfault--yay!
Maybe I missed something in the documentation that explains why package pan-git exists, but for now, it's confusing to anyone wanting to build a functioning instance of Pan on their system.
The package that actually compiled to a properly functioning application is this one, pan-gtk3:

thanks

-git packages may be providing a more up to date software as it uses git instead of formal releases as the source.
I can't access AUR atm, I'll have a look later. Fixed itself.
Edit: You can just check the PKGBUILDS and see the differences
https://aur.archlinux.org/packages.php?ID=43523
https://aur.archlinux.org/packages.php?ID=31228 includes "Temporary bugfix version by K. Haley. With nzb gui patch by Heinrich Mueller." - as mentioned in the description
https://aur.archlinux.org/packages.php?ID=43523 - uses gtk2

The "Package" class

Hi all,
Why the java.lang.Package class is not declared final?
Thanx,
Adrian.

I will give you an example:
During two weeks I'm trying to understand the
class-loader mechanism.
I read every possible article I could found - and
still I find that it
is a mysterious design. That's because the Java
platform (as Microsoft's platform) is an evolving
platform, and today's solutions come to repair
yesterday's mistakes.
Yet, another example is AWT/Swing.Maybe you don't understand the meaning of 'bloated' because being "mysterious" has nothing to do with being bloated. The class-loader mechanism is not mysterious to me and I don't see why Package not being final makes it mysterious. It's impossible to extend Package so making it final wouldn't have any functional effect, though, for completeness it would make sense to mark it final.

It doesn't appear that you save the check selection state anywhere, so therefore your renderer (not the cell editor's renderer) doesn't know when a cell should be rendered as checked.
The following is an example of check list, but note that it doesn't use the cell editor routine. Instead it is dependent on:
[http://code.google.com/p/aephyr/source/browse/trunk/src/aephyr/swing/RolloverSupport.java]
In fact, the following code's sole existence was to test that class in some type of scenario that would actually be useful. Note that the check selection model is differentiated from the normal selection model - that is necessary unless you do some rewiring of the InputMap/ActionMap so that it doesn't behave funky. Also note that for JTree, TreeSelectionModel will have to be used... and if you happen to decide to use the RolloverSupport way, RolloverSupprt.Tree in replace of RolloverSupport.List... The only real benefit of using RolloverSupport for this is that it seamlessly gives the component cell rollover feedback as long as the UI of JCheckBox paints differently upon rollover.

Unresolved argument help

I'm getting "Meat cannot be resolved" error on the following code and can't figure out why. Meat is a class in my Alpha package and I'm trying to pass the class name as and argument to orderFood method. This happens with all the classes and I can't figure out why.
package Alpha;
import java.util.*;
import csci130.KeyboardReader;
public class Pantry {
     List<Garnish> garnishes;
     List<Sauce> sauces;
     List<Meat> meats;
     public Pantry(){
          List<Garnish> garnishes= new ArrayList(10);
          List<Sauce> sauces= new ArrayList(10);
          List<Meat> meats= new ArrayList(10);
          orderFood(Meat, 10);
          orderFood(Garnish, 10);
          orderFood(Sauce, 10);
     }It doesn't give an error when using it as a Generic for the List, only when I try to pass it as an argument or use the constructor. Thanks for the help.

Here is the oderFood method
public void orderFood(Class foodType, int numItems){
          for(int i= 0; i <= numItems; i++){
               addFood(foodType.newInstance());
     }But I don't think it's because it's not initialized, because it takes a Class argument, not an object.

With the good help of irc people I discovered that makepkg was not extracting archives before it tried to use them to make a package. (An example in this case would be it not extracting opera-10.00.gcc4-qt4.x86_64.bz2 and then trying to use what would have resulted from its extraction to actually make the application.) This is why it would give the "No such file or directory" error.
I havn't the slightest clue why packages aren't extracting. Any ideas?

I edited my makepkg as follows:
642 # fix flyspray #6246
643 local file_type=$(file -bizL "$file")
644 echo "FILE TYPE: $file_type"
645 local cmd=''

Error: Makepkg was unable to build opera package.
I have a limited understanding of this, I'm guessing makepkg does not recognize the binary and so it skips it?
@iBertus: Thanks for veryifying it works on you 64 bit arch. However I've had this problem on 32 bit arch also.

Is ArchLinux Too Good?

I have been using Arch for a number of years but there is a problem ... everything always works perfectly and hence it is boring!
So I was using KDE for many months and nothing ever crashed and always worked perfectly. So to spice things up, I started using other window managers / desktop managers. They all work perfectly as well.
Hmm .. so I try out other distributions (like Ubuntu, Fedora, Puppy, Slax etc etc .. I have tried them all) .. and they seem to crash and have endless problems. So I go back to Arch.
I have tried moving to Testing & Unstable Arch repositories but they would eventually trip me up and I would be stuck
This cycle has now been occurring for 3 years.
What should I do?

dhave has touched on some of the Real-Life possibilities, so I won't go there. From a strictly Arch perspective, how about these:
Allan wrote:Surely your are affected by one of the greater than 500 bug reports (http://bugs.archlinux.org/index.php?project=1). If not, install the relevant package and have problems!
... and then solve the problem, and post the fix in the bug report.
Contribute to the wiki - new articles, amendments/corrections to existing articles, etc.
Work on an Arch project - take your pick from projects.archlinux.org, checkout the code, do stuff to it.
Try [testing] again, but with more thorough preparation i.e. inform yourself why packages are in testing, read about the testing version, get an idea of what to expect. If it "trips you up" again, try to work out why. If you find a bug, report it, preferably with a fix.
More generally, I know that there are numerous aspects of open source development that I would like to know about, but I just can't get around to them all. If you feel that too, pick one, or a few, and make yourself an expert.

Kde-snapshot repo

Welcome to kde-snapshots repo.
These are development snapshots: unstable, unpredictable, sometimes unusable...if you are not a KDE developer, addicted to bleeding-edge software or insane, I recommend you to stay at the stable KDE from [extra]. Backup your ~/.kde4 before updating!!!!!.
If I still haven't discouraged you, here is pacman.conf entry:
#x86_64 users
[kde-snapshots]
Server=http://arch.morrigan.ch/kde-snapshots/os/x86_64/
[kde-snapshots-extra]
Server=http://arch.morrigan.ch/kde-snapshots-extra/os/x86_64/
(i686 packages are no longer available)
Put these entries ABOVE [extra] and [testing].
The repository is now maintained by Zolnierz.
Current KDE version: 4.7.x (4.8 devel)
If you find a bug, please report it to bugs.kde.org. Packages contain full debug symbols, so traces are very useful in most cases and it's also a reason why packages are so big in compare with those from [extra].
PKGBUILDs and build scripts (originally by Pierre Schmitz) are available in Gitorious on http://gitorious.org/kde-snapshots-repo .

Not yet. KDE 4.3 is not even out yet, so you can't expect large obvious changes. Mostly there are bugfixes and improvements that did not make it into KDE 4.3.
Look on techbase.kde.org, you can find there more informations about the future plans for KDE 4.4 (the list is not finished yet). As those things will get implemented, you will see the differences between 4.3 and 4.4.
However my personal opinion is, that the difference between .3 and .4 will not be as big as was between 4.2 and 4.3. 4.3 is yet quite stable, good enough for common use and developers will focus on smaller things, details that were not so important and they were not submitted before 4.3 feature-freeze.

Unfortunetly you cant really delete forum topics but actually you can report abuse on the topyc and that will be reviewed by the maintenance guys and be deleted or just leave it as it is so it will be burried under other topics in no time

Large application

I am having one large javacard application. I tried to split the code from one javacard package to three javacard packages. Then I build the project, but I saw that only the Java card applet class file was produced, nothing else. The other javacard files are not build. According to that the cap is not generated. I interprate the library package as a Java package. Before this attempt I created three JavaCard projects. Only one was containing Java Card applet. One java card project was referencing other two. But neither this solution was working. What else can I try to split large application is components.

Problem solved: I use different packages for my code, then in eclipse for JavaCard project do next: right click on project folder->Build path->Link sources->browse -> add folder which contain needed package.
Then need to configure aid, of this packet. Then don`t forget about adding packet for upload: Open Debug Configuration->Choose package upload->add package->select package that was add. Move package with your applet down, because javacard try to find reference for classes when install applet, that why packages need to be upload in right order.

Why packages ??/
