Is it possible to get the Source from the Compiled Java Class File?

Hello All,
I wrote a java file which uses Java Swing to crea a GUI.I have also compiled the jave file.
The problem now is that i've made many changes and compiled it many times.Now suddenly due to some problem,the contents of tha Java file have been deleted and it shows 0 bytes.
Is there any way to recover my Java source file from the Class file?I would be thankful to anyone who can help me out on this.
Thanks in Advance,
Regards,
Vijayakannan

Yes and no, you can reverse engineer it to an extent, it wont look exactly like your original source though, it'll be full of commented out bytecode bits etc. As its your own code though you've got the best chance of deciphering it. Go to somewhere like www.tucows.com to download the software for doing it.

  • LabVIEW DSC: How to get alarm status from the area?

    Colleagues,
    I have, lets say, 50 Shared Variables where alarming enabled. Some of these variables assigned to area, so I can get status of the entire area or acknowledge an entire area of alarms (prior to version 8.x there was groups of the tags).
    Now I would like to get alarm status from the entire area. How can I do it?
    In version 6 I was able to wire tag group to Get Alarm Summary Status. Now, in version 8, Alarm Status.vi can be wired to the array of the variables, but not to area. Is it possible to get all variables from the area?
    regards,
    Andrey.

    I am not sure if I should be posting my problem under this particular topic. I am having trouble understanding acknowledge alarm vi and what this vi is supposed to do is not clear to me yet.
    I have around 300 shared variables in my project and I have created a particular vi just to view the alarms that may pop up during runs. I created a main menu and this alarm vi can be accessed upon a button click in the main menu. Users get alarm alert based on sound configuration. Then he can navigate to the alarm vi and acknowledge the alarm. The alarm vi only contains alarm and event display found under DSC module.
    The problem is everytime I click the alarm button in the main menu, it takes around 2 minutes for the alarm vi to update which is very annoying and unsatisfactory in the middle of run. I am not sure why it happens and I haven't got any response from support yet. These shared variables are managed under 10 different library files that are set up based on different loops of the process (flow, pressure and so on).
    Then I looked into three alarm examples that ship with DSC module. None of these examples use acknowledge alarm vi. I implemented another vi similar to alarm demo vi in that example - containing multicolumn listbox. I created acknowledge event containing acknowledge button and used the acknowledge alarm vi under this event. Read vi alarm is under timeout event.
    When I click the acknowledge button  as soon as I see the alarm in multicolumn listbox, nothing happens - the color of font does not get changed to purple neither any alarms get acknowledged. I tried to aknowledge alarm by variable name or  alarms or alarm area, it does not give me anything. What is this acknowledge alarm supposed to do? I tried to find examples everywhere in the web that uses this particular vi and haven't found one yet.

  • Is it possible to get the information from the complete forms send to different email account

    When i have a paid account is it than possible to get the information from the different forms send to seperate emailaddresses.
    Who dont have a account from formscentral but just need the information directly in there own inboxes?
    Because we're looking for a good and simple way to make qoustion & complain forms. But these need to go to different people in the company.

    You can have notifications sent to multiple email addresses, but each will need to have a FormsCentral account.  They can be free accounts.  What you do is create your form and set up the email addresses that you want the information to go to to be Co-authors or Contributors.  The co-author/contributor accounts will then need to log into FormsCentral, go to the Options tab and check the email notifications checkbox. 
    I hope this helps.

  • Is it possible to get the image from the i pad when mirroring via Apple TV to fill the screen instead of appearing as a screen within a screen?

    When mirroring, is it possible to get the image from the ipad to fill the screen on the TV instead of appearing as a screen within a screen?

    Welcome to the Apple Community.
    No, the iPad has an aspect ratio of 4:3, a TV has an aspect ratio of 16:9, to fit one into the other is impossible without distorting the picture. If your TV has a zoom feature, you may be able to use this to fill the screen a little more to your liking, but this will result in cropping top and bottom.

  • Spill water on my Iphone and I want to recover photos on my Ipad The pictures on the Iphone were not shared with other apple devices is it possible get my photos from the iCloud ?

    spill water on my Iphone and I want to recover photos on my Ipad The pictures on the Iphone were not shared with other apple devices is it possible get my photos from the iCloud ?

    Had you set your iPhone up to use Photo Stream?
    Had your performed an iCloud backup of your iPhone before it was damaged?
    If you did neither of the above, then your photos are not in the cloud, and they are gone.
    If you performed an iCloud backup, then it would contain the photos in the iPhone's Camera Roll (taken on the iPhone) at the time of your last backup.  You could restore this iCloud backup to a device.
    If your iPhone used Photo Stream, those photos are immediately accessible to your iPad if you set it up to use the same Photo Stream.

  • Analyse big data in Excel? Why the dynamic tables doesn't take all the data from the source table.

    Hi,
    I'm doing a internship in a production line.
    My job is to recover production data (input data) and test data (output data) using various types of software (excel, BusinessObject sap, etc).
    To this day, I have recovered hundreds of production data, and have also organized in excel but I need to analyze and plot them.
    I would like to know who can give me an idea of ​​how I could plot as much data and analysis.
    Now i trying to use dynamic charts and plot some data but I did not get acceptable answers.
    How could I compare, analyze and graph for example:
    Five columns of production (input) with five (5) columns tested (data output).
    After graphing.
    Someone can give me a technique to analyze data? ie I compare column by column?
    or some other technique? as a conglomerate could analyze data?
    o give you an idea of ​​the contect, now I perform an internship in a manufacturing turbines.
    My job is to analyze the input data (production) and to estimate the possible behavior of the turbines in the tests.
    As I said, use dynamic tables in excel, but i have not idea why the dynamic tables doesn't  take all the data from the source table.
    I appreciate your advice
    Thanks

    You can declare as PT source whole Columns [$A:$E], without rows number.
    Then You'll have all actually data.

  • How do I get routing data from the Map App (powered by TomTom) so I can display the point-to-point annotations (turn-by-turn navigation) without leaving my own application.

    I have a tableView displaying a list of contacts from a Cloud Database.  After selecting a contact, I push to a programmatically created MKMapView.  Then I display the initial region (the view) that includes the users current location (starting point) and their selected destination (end point).
    Now I want to display annotations (as described in the Location Awareness Programming Guide) that displays polylines which will represent the turn-by-turn navigation IN MY OWN APPLICATION, and not in the Map App currently used in IOS6. 
    Due to licensing and its becoming depricated in IOS 6, I do not want to get routing data from the Google Maps API.  How do I get routing data from the IOS 6 Map App (powered by TomTom) so I can display the point-to-point annotations (turn-by-turn navigation) without leaving my own application?
    I checked out Stack Overflow and other forums which basically left me with the impression that this is not possible. I also checked out the TomTom iPhone Mobile SDK User Guide from the TomTom Developer Portal and am still confused.  It must be possible to retrieve routes, since the Map App can display turn-by-turn directions.  How can I retrieve turn-by-turn data that I may display as a route within my own application?

    Thanks Michael. Apologies for the slow reply I was away for a bit (holiday blitz at work and visiting family madness etc.etc.) back now, I set both options you requested to "never " and retried the CMS software with no change. 
    I do have progress of a sort though, as a test I took a separate test PC and put a clean install of Win7 on and loaded up the CMS software (it worked perfectly) and then took the version of ole32.dll off that machine and put it onto the computer I had built
    for her (using Linux) and...
    got a new error code. Darn I was so sure I had found a clever solution this time lol.
    Anyway now when the CMS fails it gives me a similar error but the offending module is "ntdll.dll" sooo... I tried taking the "working" version of ntdll.dll from the test box and moving it over (making sure to back up the existing ones
    first so I could put them back if needed) to her new PC and the PC would not boot. 
    It seems to want the original versions of a few Dynamic Link Libraries and if I could somehow give it those while not breaking Win7 it should theoretically work seeing as it no longer errors with ole32.dll. 
    ntdll.dll however seems necessary for Win7 to boot.
    So what I am wondering now is:
    Is there some way to have both versions of the DLL file in the system32 folder (bypassing the "cannot have two files with the exact same name in the same folder" thing) or rename the original DLL's something else and somehow make the CMS look for
    the new named versions so the system has the updated DLL's it needs to boot/run and the CMS has the old ones it wants to run or is there someway to have a self contained install of the CMS, say on a USB flash drive and give it it's own E:/windows/system32/needed
    dll's  path to the files it needs? 
    Willing to try any other options or settings you may have come up with as well.
    Thanks again for your reply and my apologies for not answering sooner.

    Did you check your security software (firewall)?
    A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
    Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

  • Is it possible to delete a relationship from the BP ?

    Hello experts,
    I'd would like to replace a function partner SH (having the same number as the DO) by another  from R3 to CRM5.
    At the begining i have in R3 this partner
    AG 3901007
    RE 3901007
    RG 3901007
    WE 3901007
    In R3 by the transaction VD02, I replace the partner SH by another
    After the modify i have in R3.
    AG 3901007
    RE 3901007
    RG 3901007
    WE 5000000
    When the replication is done in CRM using BDOC, i can see, by the transaction BP
    the new ship to party partner(5000000) .
    The trouble is :
    When customer access to ISA (standard version) to order product, he can select the partner 3901007 as shipping adress.
    By ISA, he should have the partner 5000000 only.
    Is it standard or is it a sap trouble ?
    Is it possible to delete a relationship from the BP ?
    I don't want to delete the BP partner, i just want to delete the relationship when then BDOC arrive in CRM.
    i have found the oss note 596334 497146 757955 too but it doesn't bring me a solution.
    Best regards
    Christophe

    Hello
    When you delete a Partner Function in R/3 the corresponding relationshipdoesn't get deleted in CRM. This is standard SAP behavior and not a
    bug. Reason for this behavior has been explained in Note 490454.
    You can change this behavior by implementing Note 497146. Also check
    the note 682427 which will help you in clearing old data.
