How to implement Enum (like in c)

Hi !
I want to modify some values using enum, like in c.
How can I do it ?
Example: authorization = enam {trainee, trainer, supervisor}
10x

Actually I just tracked down that article a few
minutes ago:

How to implement bundle-like mechanism in Arch Linux

I like Chakra's bundle system and I want to make it in Arch.
I heard that bundle system is just a separate file system(like loop? I am not sure).
Can you give some details?
However, I think there must be some reasons that Arch does not implement such a convenient tool as bundle system.
I want to hear about these reasons.
Thank you.

If you go back more in the history behind Chakra, how it came to live, you might know, it started bc of a desire to do another split. That one was for KDE, resulting in KDEmod, which was fully accepted by Arch, a few years after, and is currently the way KDE is build in Arch too (KDE being split in multiple packages).
While Chakra was just Arch + KDEmod, more and more users stated, there was a desire to split toolkits too. Have a system that was either based on GTK, and for Chakra users, a system base on just Qt/KDE. When the late Chakra founder Jan Mette called the meeting in February 2010 the discuss the plans for a full split from Arch, this desire expressed by many users was one of the driving factors for his decision.
To have a fully functioning distro, and doing something this different, the discussion included finding some MacOS way of including some of the most well known, and revered Linux apps, that were GTK based. That is how the idea of bundles came to fruit.
At the start, a few hundred packages had either makedeps or full dependency to gtk2, so it was left up to the user to install those apps, though the ISO's were gtk free.
Once the bundles became more functional, and included all those most well known and revered Linux apps, the majority of the gtk apps were removed (slowly) from all repo's. Plus in the good 2 years since, many apps/libs have been stripped of gtk, since many apps are build to function on both gtk and qt based systems, though they do not need the gtk libs at all to work just fine on a qt based system. To remove gtk libs/functions from one app, makes very little difference, for ten, it is not a big difference, but you repeat it over a hundred times.....
GTK is still in the repo's, and probably will stay there. Users who do not want to stay gtk free have added many such apps in ccr, and as a service to them, it is nice to not have to compile gtk. Plus there is no real solid substitute yet for flash, again as a service, it is still an option. The bundle buildsystem also draws from the repo's, if a certain lib/app is set to draw from there during the bundle process, that is another reason gtk/gtk-apps are still in the repo's.
As Allan states, downloading multiple bundles, will download multiple instance of a highly compressed gtk (or other lib/app). This is ofc a draw back for bundles, but again, a well thought out, and chosen draw back. Users who need more then 4-5 bundles, should really rethink using a distro that made the choice to see if a distro can be fully functional, when splitting toolkits. Those users can install their needed apps from ccr, or perhaps should choose another distro. But to have an application not needing a rebuild/break bc of a .so update is a big plus. When libreoffice was not stripped of it's gtk deps, it was one of those bundles. It included all, and one such bundle still runs perfectly on one of my installs, it was build February 2011 (granted, I'm using this one as a test case for bundle longevity).
For those who do not need but 3-5 bundles, there is no gtk installed (takes more room, then downloading it in compressed form a few times). And many bundles do contain more then one gtk app (GIMP bundle includes xsane for example, chromium includes flash, google-talkplugin, pdf plugin), so as an example in my case, I run one bundle almost all the time, and it brings me the only 3 gtk apps I need and I my installs are gtk free. Btw, all bundled browser include the flashplugin.
But bundles are not just for gtk, Skype is another example for bundle use. This app brings in about 50 lib32 packages, if you are on x86_64, why install all those for just one app? Some will state, it makes no difference, don't care to have a lot of extra libs installed, some will prefer to keep a more "clean" system. Chakra goes with the latter.
Since the bundle process can draw from the repo's, or build all needed packages in that system, in any setting chosen, any security update is no extra work, then any other rebuild. That security update was either done in the regular repo's, all needed then is rebundle all included apps (the final bundle process, squash them, etc, takes about 40 secs), or if the apps is not in the repo's, just that one is rebuild/adjusted in the bundle system, and again, bundled with the rest of the existing packages included in that particular bundle.
To address as a final note, the point made, you can't be bleeding edge bc of bundles. I'll give the example of the gimp-dev bundle. It needed the latest babl, gegl, much newer glib2, gtk2 (and more from that stack) then was in the repo's. All those were updated in the bundle system (though not a visible repo, the bundle build system has some 200-250 packages at most times), tested and ran successfully for many users, and always making the latest dev version available for gimp, until the final release this week. Since all glib2 updates were tested in this bundle for quite some time, when it was time for this update in the regular repo's, it was a simple and quick update for the whole stack.
Bundles are not perfect at this stage, far from it, there are still many plans to improve on the whole system, but for something that is in use just 1 1/2 years, it truly is a viable option to have a system running on a single tooolkit.
To address a question posted while writing this. Chakra uses testing repo's a lot too. Bundles are fully rolling, always the latest available, just like the apps and games repo in Chakra.

How to implement table like structure in MIDP?

I am a starter of midp, and now need to implement something using MIDP 1.0.
I would like to know can I have table like structure in MIDP, just like HTML; or I can only work with List/Form (one dimension display). I can't find related information at api doc come with wireless toolkits

not really knowing what you want to acomplish I have this suggestion: check Mobile Information Device Profile (JSR-37) at http://www.jcp.org/aboutJava/communityprocess/final/jsr037/index.html . This might shed more light on applicable classes/methods/interfaces within MIDP 1.0.

How to implement language like in SDN?

Hi,
I'm interested in changing language similar as the language setting in SDN i.e. The language option on top right hand corner, next to Log Off. Anyone know how to accomplish this?
Thanks,
Iwan

Björn,
I posted the solution in the same thread on Sept. 20, 2006, I'm not sure why you can't see the solution. Did you read the whole thread? I did not mentioned any servlet filter at all in the solution. I went that approach and got help from Darrell (forgot his last name) from SAP. The solution he provided me was way over my head and got another solution that works for me and I posted this in this thread on Sept. 20 so if someone have the same problem will be able to use this solution.
The meat of the solution:
When you create a resource file, SAP by default create this file under localization folder. We need to move this file to private/classes folder instead. This way, when we use a new Locale and get the resource bundle for that new local, the resource file can be found.
The following is my post which you can see it as separate post in this thread as well.
Start of duplicate posting -
FYI, found the solution.
I put the properties file in private/classes instead in localization, and then user ResourceBundle and Locale combo.
Locale myLocale = new Locale("es","CO");
ResourceBundle resc = ResourceBundle.getBundle("label",myLocale);
response.write(resc.getString("text1"));
This will pick up your assign Locale instead of portal/component Locale."

How to implement Strategy pattern in ABAP Objects?

Hello,
I have a problem where I need to implement different algorithms, depending on the type of input. Example: I have to calculate a Present Value, sometimes with payments in advance, sometimes payment in arrear.
From documentation and to enhance my ABAP Objects skills, I would like to implement the strategy pattern. It sounds the right solution for the problem.
Hence I need some help in implementing this pattern in OO. I have some basic OO skills, but still learning.
Has somebody already implemented this pattern in ABAP OO and can give me some input. Or is there any documentation how to implement it?
Thanks and regards,
Tapio

How to implement a single sign on feature using java.

Hi,
I have a question like , How to implement **single sign on** feature in java without using any third party framework or tool like LDAP or any other which is available in the market.
Actually the situation is i have all security information into the table and those information is used for single sign on . If a user logged in from a jsp loging page all the security role should be assigned to that particular user.
We can do this using LDAP but i am not supposed to use the LDAP or any third party tool . I have to write a java class for that .
please suggest me the method , how to implement this in a web application.
Edited by: Rakesh_Singh on Mar 19, 2008 11:55 AM

you could setup a token that specifies a user is authenticated. other applications that u want SSO can check for existance of this token
if it is HTTP - you can save the token as a cookie and downstream apps look for this token
yr code needs to validate that the token/cookie was indeed a valid one and not subject to man-in-the middle attack.

Hi
if you don't want to aggregate try to define a user function
analytic_sum($(value))
implémented by
sum($(value))
after that
replace your
sum(NOTICES) over ( partition by property order by RELAVANTDATE range between interval '30' day preceding and current row)
by
analytic_sum(NOTICES) over ( partition by property order by RELAVANTDATE range between interval '30' day preceding and current row)

How to implement this function in JSP/Servlet env?

Hi all,
I working on a project, it provides functionality to upload file using JSP/Servlet. In the first JSP page, there is file location and submit button. After user select a file to upload and click submit button, a message, like "sending file to XXXX", will be shown on the screen. Once uploading and validation are done on the server-side, a successful/error msg will be shown to user.
Here I have a question for the "sending..." msg and the successful/error msg. They should be put in one jsp page or in two separate page? how to implement them?
Thanks for any help!
Tranquil

For the sending message... Well, the thing is, when you click submit, it's sending the file to the server and the server is processing it, and this is all done before the "complete" page is sent to the server. So one would need to use some Javascript on the page before the actual submit happens to show some message. This is done on Ebay when you put something for sale, you can upload an image, and there is a little popup message telling you that it's uploading, and it is removed when the process is done. Now, I'm not sure the exact details of how this works, but my educated guess is this:
1) The onsubmit function of the form checks that the file upload fields have a value (no need to popup a message if no file upload, since that's what usually takes the time, although it could just be assumed there is a file). If a file is to be uploaded, or just want to show the message anyway, a new popup window is opened with the window.open method and the "sending" message is shown (either written via Javascript or just load a small web page to the window).
2) The popup window, since you can't transfer the window object from the form page to the next page, has to check window.opener for some value that the success/error page would have to set. The success/error page could use it's body onload function to set a variable in it's own window object to denote that the page is loaded. The popup window can use a looping check using setTimeout or setInterval in Javascript to check for window.opener.isLoadedVariable to be present, and if so, close itself.
I've never done that, but I see no reason why it wouldn't work.
