is mysql a free open source database or do you need a license for it in production.

Hi,
It should be free under GPL (General Public license).Usually it will comes with your operating system distribution (eg:RHEL)
If you download it from Oracle site, it should have the commercial license tied to it, and you need to pay for that if it is in use for production.

    I haven't tried ICEFaces or JBoss seam or Apache MyFaces, so I can't really compare them.
    ICEFaces appears to be a nice framework/tool from looking at their site, even though it's open source I think one has to pay for support, you might want to take that into consideration while making your decision.
    Apache MyFaces, is fully community driven - so you get free support from the community.
    I don't know about JBoss seam.

    I have been looking into MySql and its not really impressed me. Not sure that there is anything better.
    And it depends on your usage.
    InstantDB is one http://www.lutris.com/downloads/index.html but it is limited to non-commercial use.
    Interbase (firebird) at http://firebird.sourceforge.net/
    I believe the unix side usually supports a variety that you could probably search for.
    And if cheap is ok, rather than free and open, and using it only for developement then you can get full versions of Oracle and MS SQL Server very cheaply.

    Don't give up just because there are other options out there.
    Adobe is only giving up the free tool for education purposes, or unemployed developer.  You didn't say if you were one of those.
    I believe over time there will be plenty of room for alternate IDE approaches that support the Flex Framework; and in fact there are quite a few options already out there.

  • ADF (View Object) with open source database

    Hi all,
    Recently, I am evaluating JDeveloper 9.0.5.2 ADF with an open source database (Firebird).
    I follow the instruction to:
    1. Create an entity object
    2. Create a view object for the entity object in 1
    3. Create an application module for the view object in 2
    4. Right click on the application module and test -> all worked fine
    5. I created a jsp and drag the view (in 2) to it from Data Control Palette
    6. Test it in OC4J -> an error occurred (not because of jdbc config)
    JBO-27122: SQL error during statement preparation. Statement: SELECT * FROM (SELECT Department.DEPT_NO, Department.DEPARTMENT AS DEPARTMENT1, Department.HEAD_DEPT, Department.MNGR_NO, Department.BUDGET, Department.LOCATION, Department.PHONE_NO FROM DEPARTMENT Department) QRSLT ORDER BY DEPT_NO
    GDS Exception. 335544569. Dynamic SQL Error SQL error code = -104 Token unknown - line 1, char 16 SELECT
    To my knowledge, the error should be due to Firebird doesn't support the query syntax " select * (select col1, col2... from table) QRSLT where... order by... "
    I am quite headache as this query is automatically generated by JDeveloper. I am figuring out whether I can change it. It seems that I have to play with the ViewObjectImpl class.
    I do think ADF is an amazing technology. However, is it only so amazing with the Oracle technologies? Please correct me if I am wrong.
    Hons

    Dear Shay Shmeltzer,
    Thank you for your reply. After hours of trying on Firebird, I still get the error:
    JBO-27122: SQL error during statement preparation. Statement: SELECT * FROM (SELECT Department.DEPT_NO, Department.DEPARTMENT AS DEPARTMENT1, Department.HEAD_DEPT, Department.MNGR_NO, Department.BUDGET, Department.LOCATION, Department.PHONE_NO FROM DEPARTMENT Department) QRSLT ORDER BY DEPT_NO
    GDS Exception. 335544569. Dynamic SQL Error SQL error code = -104 Token unknown - line 1, char 16 SELECT
    I then downloaded the MySQL 4.0 and install on my system to do the exact procedures. No error! Thing works fine! Oh man...
    For the Firebird case, a strange thing to note is that the data table (I dragged) contains data, but the error message is on top of it.
    Actually, I don't have a particular database preference but I do hope ADF can work equally for these open-source databases. I think the problem may also be contributed by Firebird. Hope that I can figure it out this week.
    Regards,
    Hons

  • Free / open source Closed Captioning software?

    I'd like to add closed captions to a feature film I produced. I understand the difference between closed captioning (which is embedded in the video and decoded by the TV) and DVD subtitles, and I would like to add real closed captioning.
    Is there any free / open source Mac-compatible closed captioning software I can use to add captions to my feature film and create a .cc file for importing into DVD Studio Pro?
    I'm more than comfortable with steep learning curves and X11 interfaces. If I have to use a text editor and timecodes, that's fine too. I just need that .cc file to add true closed captioning to my video, and I don't have the dough for commercial CC software.
    Thanks!

    my company does offer closed captioning as a service, Kelly is correct when he says the software is very expensive. as far as creating a .scc file with a text editor, i don't believe it is possible but i may be wrong. when opening a .scc or .cc file in a text editor, it does look like a bunch of "gobbledygook". but the .cap file that is used to create the .scc or .cc file looks a bit more manageable and could possibly be created without captioning software, again i may be wrong and have never attempted to do it. but say you could do it, you could save a bunch of money by creating the .cap file and giving it to someone who has the software to convert it to .scc or .cc. if that seems overwhelming and want to job it out, you could save some money by transcribing the video yourself which is a significant part of the cost when outsourcing. here is a sample of what a .cap file looks like:

  • Free/open source plotting software

    The objective:
    Data processing, mostly one X and one Y axis, recorded from sensors.
    Formatting, to change how the chart looks, e.g. fonts of the axis label, weight and dashed lines of the plot, addition of lines or arrows.
    What's been found:
    Gnumeric and google spreadsheet.
    There is a wonder what the Free/open source software users among the research people are using. I ran into LaTeX and thinks it's a good software. Anything like this would be nice.
    Thanks.

    Fine. I found QtiPlot working really well on Linux systems with ease of availability free of charge. No flame setting (as I think Mac OS and linux are both Unix-like), but it's a bit hard to compile on Mac OS X.

  • Free open-source WIG (Wireless Internet Gateway)

    Hello guys
    I'm ttrying to develop a system that anables communication between the cell phone and the web server via sms (sms platform). Don't you guys know of any free open-source WIG gateway that is readily available for downloads?
    Also, is there anyone here who has developed this type of system? how did you do it? any advices or suggestion.?
    thank you to tou all of you in advance.

    I am not an expert, however, I have noticed very similar issues with the 2Wire equipment. I visit a local coffee shop daily and was perplexed why my MacBook Pro was successfully connected with a strong signal but would have a self-addressed IP address for up to 10-min. Other times, the whole network would go down when a new computer would connect, usually mine.
    After reviewing the topic, once again, I am coming to the belief that it is just the 2Wire Gateway that is at the center of these issues. My suggestion is to get a separate modem and wireless router. I am also with AT&T at my home and I use their Motorola SpeedStream modem and a Netgear Router. I cant say that I never have issues, however, at most, I get some easy to resolve problem come up once a month or so.
    Best of luck to you...

  • Some files in "DOCUMENTS" icon in dock won't open. Get msg saying You need a newer version of Pages to open this document." Have Pages 4.1 installed.  Same files will open ok from Finder, Pages App. Recently sync'd with ipad2 (Pages) after iOS5 installed.

    Some files in "DOCUMENTS" icon in dock won't open. Get msg saying "You need a newer version of Pages to open this document." Already have Pages 4.1 installed.  Same files will open ok from Finder/Pages App./selected file. Prob not noted until recently after sync'd with ipad2 (Pages) when I installed iOS5. Anyone-- please?!

    You have 2 versions of Pages on your Mac.
    Pages 5.2 is in your Applications folder.
    Pages '09/'08 is in your Applications/iWork folder.
    You are alternately opening the wrong versions.
    Pages '09/'08 can not open Pages 5 files and you will get the warning that you need a newer version.
    Pages 5.2 can open Pages '09 files but may damage/alter them. It can not open Pages '08 files at all.
    Older versions of Pages 5 can not open files from later versions of Pages 5.
    Once opened and saved in Pages 5 the Pages '09 files can not be opened in Pages '09.
    Anything that is saved to iCloud and opened in a newer version of Pages is also converted to Pages 5 files.
    All Pages files no matter what version and incompatibility have the same extension .pages.
    Pages 5 files are now only compatible with themselves on a very restricted set of hardware, software and Operating Systems and will not transfer correctly on any other server software than iCloud.
    Apple has removed almost 100 features from Pages 5 and added many bugs:

    I recently did a system update and installed Yosemite on my Mac. Now I am unable to open CS5 at all. The error message I get is this: "To open Adobe Photoshop CS5.1, you need to install legacy Java SE 6 runtime." I have tried downloading this and it still gives me the same mess

    In the details it is mentioned that it is an outdated version of Java.
    Is this a security risk that i need to live with to get CS5 to run with Yosemite?
    Also i need to reject messages from Java in the future about updates, or not?
    thx for any input

    I recently loaded OSX mavericks on my Imac. I now find I cannot open any Adobe products from CS5. The error message reads " to open Adobe illustrator CS5.app, you need to install a JAva SE 6 runtime. Would you like to check and install one? I try to install but get the error" download error". As far as i know I'm using Adobe Java 7. None of my CS5 suite works anymore............and i really dont want to upgrade to a monthly cloud service fee as i hate this policy with a passion.

    This goes for Dreamweaver CC on Mavericks!!!!! THANK YOU!
    I couldn't launch Dreamweaver CC. An error told me to install "java se 6 runtime". But when I clicked  OK I got another error telling me there is a network problem! I found this forum post on CS6 products, so I tried the download link, installed java 6 and presto, it worked! Thanks!

  • I keep getting an error message "To open X1100 Series Button Monitor, you need to install Rosetta".  I used to have a Lexmark X1100 printer attached to this Mac.  How can I stop this error?

    I just had a new hard drive put in my IMac and ever since I got it home this error pops up "To open X1100 Series Button Monitor, you need to install Rosetta.  Would you like to install it now?  Two years ago I had a Lexmark printer attached to this Mac.  I'm not sure why this is happening as I believe I have move all Lexmark files to the Trash bin.  Does anyone know how I can stop getting this error?  Thanks.

    Check in System Preferences> Printers to see if the Lexmark is still showing in your printer list. If it is, click it and hit the minus button to remove it.
    If it's not showing, when you trashed the Lexmark software, did you notice if there was an uninstall file? Sometimes just moving unwanted programs to the trash can doesn't get rid of all of the installed software and the software manufacturers include an uninstall option to remove those 'hidden additional files'.
    Check support at Lexmark's web site to see if they offer a solution.
