Will JSE integrate more 3rd-party open source tools in the future?

Looks like this issue is the same as the one tracked in:
http://swforum.sun.com/jive/thread.jspa?threadID=57046
Also, the thread http://swforum.sun.com/jive/thread.jspa?threadID=55897 discusses the topic "SJS8EA: how to add netbeans4.1 update center" ; users can add nb41 update center to jse and download and install the modules from netbeans update center. Users can also obtain the nbms directly from netbeans.org and other third party vendors and apply them to jse using "manually downloaded modules" option in autoupdate client. Of course, users should ensure that the downloaded modules are compatible with the version of nb a given jse version is based on.

Relying on 3rd-Party/Open Source Software for fully functionality in Vi

Is it just me or are open source software engineers doing a better job than actual Creative software engineers?
There are several threads linking to 3rd-Party hacks to get the majority of Creative Apps working in Vista. As well as this there are the KXProject Drivers floating around which appear to offer better compatability than the current Creative drivers.
What's going on Creative? How many Software Engineers do you actually have working for you?
Why is it, people you don't even pay are making much greater developments and progress in drivers and software for Vista?
But i guess they're not charging customers to purchase?updates on?CD. I remember when the Audigy was released, instead of offering downloads, Creative actually asked people to buy an updated CD with software and drivers on. Of course we were only?charged for postage, but very expensi've postage nevertheless.Message Edited by AnnoyedCustomer on 03-09-200703:3 PM

Hi welcome to the forum, I hope you find lots of help here and we look forward to your contributions as well
In regards to your questions:
1: No, you just put a swf file on the server
2. You can host the smaller app on your site and then give them an iframe linking to it
3. Nope, no problems there
Hope this helps

I have a MacBook Pro laptop purchased in June 2011, and the superdrive no longer works. Rather than have it replaced, I'll buy a 3rd party superdrive that plugs into the USB port. Does it need it's own power source, or will the USB port suffice?

The Apple external SuperDrive actually exceeds the allowed power draw. Because of this, it is only trouble-free on certain models that accommodate this excess.
All others require an external Power source.

DBMS_CRYPTO MD5 hash value does not match 3rd party MD5 free tool

Hello,
I am using Oracle Version: 11.2.4.
I have a problem where the MD5 value from DBMS_CRYPTO does not match the hash value from 3rd party MD5 free tool (MD5 Checksum Calculator 0.0.5.58 or WinMD5Free v1.20) and also the MD5 hash value calculated by an ingestion tool where I am transferring files to. The MD5 hash value that the ingestion tool calculates is the same as the 3rd party MD5 free tools I have. This occurs only on some of the XML files that I generate using XSQL(xmlserialize, xmlagg, xmlelement, etc.) and DBMS_XSLPROCESSOR on a Linux OS. The XML files are transferred from the Unix OS to my Windows 7 OS via filezilla.
I found a thread on this forum that also had a similar issue so I copy/paste the java functions. They are listed below(both are the same expect for the character set):

And in that thread (Re: MD5 HASH computed from DBMS_CRYPTO does not match .NET MD5 I provided the reason why DBMS_CRYPTO may not match hashes produced by other methodologies.
I have no idea why you copied and posted all of that Java code the other poster and I provided since code has NOTHING to do with the problem you say you are having. Thte other poster's question was how to write Java code that would produce the same result as DBMS_CRYPTO.
You said your problem was understanding why DBMS_CRYPTO 'does not match the hash value from 3rd party MD5 free tool ...'. and I answered that in the other forum.
>
The Crypto package always converts everything to AL32UTF8 before hashing so if the .NET character set is different the hash will likely be different.
See DBMS_CRYPTO in the PL/SQL Packages and Types doc
http://docs.oracle.com/cd/B28359_01/appdev.111/b28419/d_crypto.htm
If you look at the spec header for the DBMS_CRYPTO package it shows this note:
-- Prior to encryption, hashing or keyed hashing, CLOB datatype is
-- converted to AL32UTF8. This allows cryptographic data to be
-- transferred and understood between databases with different
-- character sets, across character set changes and between
-- separate processes (for example, Java programs).
-- If your 3rd party MD5 free tool (MD5 Checksum Calculator 0.0.5.58 or WinMD5Free v1.20) do not use the AL32UTF8 character set then the hashes will likely be different. You can't modify DBMS_CRYPTO so if the hashes need to match you need to use 3rd party tools that either use the correct character set or can be configured to use the correct character set.
The problem in the other thread was how to WRITE Java code that uses the correct character set and I showed that OP how to do that.
So unless you are writing your own Java code all of that code you copied and pasted is useless for your use case.

Is SAP Netweaver environment compatible with CruiseControl open source tool

Hi All,
Can you please let me know if
Is SAP Netweaver environment compatible with CruiseControl open source tool?
If yes, steps to integrate the same.
Regards,
Raj

Ken,
Few suggestions from my side.
>>who supports the code? It's free, so there is >>no 'technical support hotline' to call. For every >>package that we install, we therefore increase our >>workload.
This varies from package to package. If you see Hibernate which is a OR mapping library, you get support for it which is run by a altogether different company but you might not get the support for your other library codes. so..varies with what you are trying to use.
>>testing strategy - how many hoops do we make the code >>go through before we can be assured that >>it's 'production' ready?
This will also depend on the free source stuff you are trying to use. Say in case of Struts or log4j like packages, you wont find any flaws as the industry is heavily relying on these today. but a new library and yes, you need fair amount of testing for that.
>>what is the SAP stance on incorporating open source >>code into the J2EE engine? Does this in any way affect >>supportability?
SAP would be the best option to enquire with :).
>>rapid change - Open source code can change quite >>rapidly, so how do you handle this?
Not necessary you have to upgrade.If a current version suffices your business requirement then stick with it.
Even if you change to a latest version,you might need to tweak with your java versions (say upgrade java also) but the existing functionality in previous versions will continue to work fine though..
Hope this helps..

More than one OPENING in FLOW_TYPE in the S Dimension

Dear BPC Experts:
        I am using BPC 7.5 NW SP09 now, and need to create more than one Opening flow members.
Can I give FLOW_TYPE OPENING to each opening flow member? Does such config affect the default caculation
behind system? Like currency conversion or carry-forward business rules? Does anyone have similiar experience?
Or I just don't have set OPENING FLOW_TYPE to those many opening flows?
BRs,
Fred Cheng

Hi,
Let me try to explain this.
Lets say you have 2 accounts - ACC1 and ACC2.
If you want to have opening flow for each of the accounts in the account dimension, itself, then you will have soemthing like
ACC1
   ACC1OPE
ACC2
   ACC2OPE
So, you see, the number of members can increase tremendously.
To overcome this problem, we use the subtable type of dimension. In this dimension, you will have only one member for opening flow - OPE
No, the if you look at the data region ACC1 and OPE, it will show you the opening value of ACC1,
Similarly, if you look at the region ACC2 and OPE, it will show you the opening value of ACC2.
Hope you got the idea, now.

Need open source tool

i want to add a private key into a certificate file
what open source tool i can use ?

you are right but i did the other way around.
I have a keystore.
I extracted certificate and the private key out of that keystore (by keytool and a custom java program)
Now, i would like to share this certificate and private key to a client (for the time being its the browser) so that the browser and the server are mutually authenticated in 2 way SSL.
so, if i can make a certificate + private key file ...then i could use Browser's Import tab and will pick up the file and then i'll call a secured Web Service from the browser.

Open source tool for oracle to mysql migration

My macbook came with snow leopard, if I upgrade to Lion will I be able to use my restore disks in the future and if I do use my disks that brings me back to snow leopard, Will itunes remember I purchased Lion or will I have to purchase a second time ?

At this point, you can no longer download Lion (10.7) from the App Store, only Mountain Lion (10.8) - make sure all your applications are fully compatible if you decide to upgrade.
Yes, you can restore 10.6 using your restore disc should you wish to - and the App Store (not ITunes) will have a record of all your purchases, since it's linked to your AppleId.

When will firefox stop supporting 3rd party cookies by default much like Safari does now?

Safari by default doesn't accept 3rd party cookies and there have been reports that Firefox will follow suit. Any information in terms of the timeline as to when this will come into effect would be much appreciated!
Thanks,

You will probably see the change to only allow third-party cookies from visited sites in Firefox 26 (currently on the Aurora update channel).

Will not charge with 3rd party chargers when asleep

My iphone 3g does not charge when plugged into a 3rd party charger and the phone is asleep. I can confirm that its not charging because the phone is still out of battery even after being plugged in overnight, and the griffin charger has a LED indicator that shows if its actively charging or not. I tired this with both a Griffin iphone charger and a Belkin charger.
When waking up the phone though, it of course shows that its charging. It took me a while to figure out that it wasnt chargin when it was asleep.
Does this happen to anyone else?

Do these chargers say that they are made to work with iphone?
The iphone 3g does not charge via firewire pins as the original did. This could be your problem.
There are many posts on charging issues due to firewire compatibility. You can do a forum search to find out more.

Deleting 3rd Party Loops... where the freak are they stored???

Yes, I know that by default, loops are stored in Library/Application Support/Garageband/Apple Loops, or the similar address under my user library.
And, I know there is another folder close by, for Jam Packs.
However, I have been going INSANE, trying to find old, single-hit files and obsolete loops which i have downloaded from 3rd party sources. They are NOT in the regular places such as the Apple loops folder.
All of them were installed by drag and drop method into the Garageband loop browser, so one would assume they all went to the same place.
How in the world do i find these loops?
The Finder and Spotlight have turned up nothing.
I have about 5,000 i'd like to trash to make room for more important things.
Can Garageband be THIS cumbersome?

HangTime wrote:
yes, that was telling him to not delete it by hand because, as Christoph points out above, you then need to reindex, whereas deleting it through GB takes care of that.
with 5,000, it's probably worth the reindex, deleting one at a time through GB would be ... tiring.
Actually. i like your idea of deleting from the browser. They are scattered in different categories and different folders. I'd have to search and test them anyway... so I might as well just axe them when i come upon them in the browser.
I swear I've tried it that way before, to no avail..
Thanks a lot for you help.
