  • Compiling error need help urgently please

    im trying to compile a java file but i get the following error:
    Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/tools/javac/Main
    and im typing in the right location of the file, and the package has been set properly, some please please please help me.

    Hiya.
    I seem to get this error message too, but there was more to it. It points out a classB i'm creating an instance of in the main() of classA, that it can't find or doesn't know where to get classB.
    The program easily works in VisualAge or in Forte, but when i tried using the command line compiler from the JDK1.3, it doesn't work right.
    They are all in the same package, and I did use the package statement to also indicate that, and they are public so that's not the problem.
    Seems, i can only compile and run programs where all the custom classes are in the same java file.
    Anybody know of a tutorial that consists of a program that uses 2 or more java files (1 custom class in each file), and then shows you how to use the command line to compile and run them?

A reboot in this manner is prescribed for most glitches and operating system errors, and you will lose no data on the device doing this.
    Please let us know if that reboots the device properly or not.

  • Need help urgently with OS X and Windows 7

    I need help urgently.
    I installed Windows 7 on my macbook pro with OS X Lion. After installing Windows7, I accidently converted the basic volumes to dynamic volumes and now i can't even boot to OS X.
    Please help me how to recover my OS X Lion. If I have to delete Windows and bootcamp partitions, it is OK.
    I just want to get back my OS X bootable.
    Thanks

    Sorry
    I can't even see the OS X partition when I hold down the "Option" key.
    I could see OS X and Windows partitions if I hold down Option key before changing the partitions to Dynamic partitions from Basic in Windows 7.
    Now can't see OS X partiton and only see Winodws partition but when I tried to boot onto Windows7 , I got BSOD and macbook pro restart.
    Please help
    The usual reason for the OSX partition to be invisible under these circumstances is that it has been trashed by Windows.
    Do you have a backup?

    Subject: Need Help Urgent Please
    If is a fillable form, just tab to the next field. What we do not understand from you is IF it is a fillable form or not. If it is not, then the 3 options I gave can be used. Placing text is always a problem. You might find it useful to turn on the grid to help in placing your typewriter fields. However, if it is fillable you do not have to create any fields to type in, you just leave the tool as the hand tool and select the predefined fields with the cursor or the tab key and type accordingly. If the field is a checkbox, then you just use the space key to activate it.
    So, are we talking about a fillable form or something that has the appearance of a form, but not fields to fill in. This is what Bernd has been try to find out and you keep suggesting it is fillable as we read what you have said.

    One reason that I sometimes get 'NoSuchMethodError' is when I make a change to a
    java class that is imported into another java class. When I go to run the
    importing class, it will throw a 'NoSuchMethodError' on any methods that I've
    changed in the imported class. The solution is to recompile the importing class
    with the changed classes in the classpath.

  • Adobe Acrobat 9.0 Pro crashes at start up: Runtime Error-please help

    I have Adobe CS4 installed on my Windows 7 PC. In addition, I have Adobe Reader XI and InDesign 6 installed. If I remember correctly, after I installed Adobe Reader XI, I uninstalled the version of the Reader which came with CS4.
    So here’s my problem: When I try to download a PDF that has been sent to me in an email or open one that already exists on my computer, this happens:
    Runtime Error!
    Program: C…
    The application has requested the Runtime to terminate it in an unusual way.
    When I click OK, I get this:
    Adobe Acrobat 9.0 has stopped working.
    If I try to Adobe Acrobat 9.0 Pro from my start menu, the same thing happens.
    This makes no sense to me because
    I don’t have the knowledge to figure this out. I have no idea what Runtime is.
    Prior to a computer meltdown a couple of months ago and a complete reinstallation of everything, these very same programs all worked just fine.
    I don’t understand why, when I try to open an emailed PDF, they don’t automatically open in Adobe Reader XI rather than Adobe Acrobat. Isn’t the general idea that people be able to open and view sent PDFs which they have been sent, which is what the Reader is for, and not usually edit them, which is what Adobe Acrobat is for?
    If, instead of trying to open the emailed PDFs, I save them to my computer, I can launch Adobe Reader XI and open them from within that program without any problem. That’s OK if I just need to view the PDF, but I need to be able to edit PDFs too, so I must get Adobe Acrobat 9.0 to work.
    Would reinstalling Adobe Acrobat 9.0 Pro help? Is there a way to reinstall that program only from the installation disks or would have to reinstall CS4 entirely?
    I cannot open Adobe Acrobat 9.0 at all, so any solutions which must be done with the program open are not possible.
    I would really appreciate some help.

    SOLVED!
    Resetting Internet Explorer didn't work, Reinstalling Acrobat 9.0 Pro didn't work, but changing a registry key did.
    Here's where I found the solution:
    Microsoft Visual C++ Runtime Library error opening PDF files - Microsoft Community
    Here is the relevant post, but before you try it, read my note below:
    Hi,
    This is known issue with Acrobat for several versions now, Adobe's current fix is just to update their software: http://kb2.adobe.com/cps/404/kb404597.html
    The problem is with the application data being misdirected.
    "The affected user has a redirected Application Data folder and as a result the network path containing the Application Data uses a UNC path that begins with \\. This UNC path causes Acrobat 9.0 or Adobe Reader 9.0 to incorrectly parse the Application Data path and give the error message."
    A potential Solution would be to go into the registry. Left Click type "regedit" and right click and run the program with "run as administrator". Go to Hkey_Current_User\Software\Microsoft\Windows\Current Version\Explorer\User Shell Folders and make sure see where "AppData" is pointing. If it is pointing to "%UserProfile%/Application Data" change it to point to "%UserProfile%/AppData/Roaming".
    BUT, be careful about one thing: This poster seems to have accidentally used forward slashes when he should have use back slashes. Look at the very last line of his post where he advises "If it is pointing to "%UserProfile%/Application Data" change it to point to "%UserProfile%/AppData/Roaming". You'll find, or at least I did, that this key has a back slash, not a forward slash, so changing what I found: "%UserProfile%\Application Data" to "%UserProfile%\AppData\Roaming" worked and now Acrobat 9.0 works fine.

  • My iphone4 cannot open on screen it show usb and itunes logo...needed help urgently thanks

    Error 1603
    Follow the steps listed below for Error 1604. Also, discard the .ipsw file, open iTunes and attempt to download the update again. See the steps under Advanced Steps > Rename, move, or delete the iOS software file (.ipsw) below for file locations.If you do not want to remove the IPSW in the original user, try restoring in a new administrator user. If the issue remains, Eliminate third-party security software conflicts.
    Error 1604
    This error is often related to USB timing. Try changing USB ports, using a different dock connector to USB cable, and other available USB troubleshooting steps (troubleshooting USB connections. If you are using a dock, bypass it and connect directly to the white Apple USB dock connector cable. If the issue persists on a known-good computer, the device may need service.
    If the issue is not resolved by USB isolation troubleshooting, and another computer is not available, try these steps to resolve the issue:
    Connect the device to iTunes, confirm that the device is in Recovery Mode. If it's not in Recovery Mode,put it into Recovery Mode.
    Restore and wait for the error.
    When prompted, click OK.
    Close and reopen iTunes while the device remains connected.
    The device should now be recognized in Recovery Mode again.
    Try to restore again.
    If the steps above do not resolve the issue, try restoring using a known-good USB cable, computer, and network connection.

    note The full stack trace of the root cause is available in the Apache Tomcat/5.5.9 logs.
    i checked my database configuration and its seems that it ok(and its run with jbuilder ok).
    i need help, please!!!

    Pray tell me where in teh server.xml/context.xml will you need to >configure a datasource for a simple bridge-driver program as is >obvious from teh stack trace? gcrashed,
    When a datasource is used, the connections are retrieved from the datasource. The datasource maintains a pool of connections which can be configured. Programs can retrieve the connections from the datasource and after usage, they are returned to the datasource. Since it is the server that maintains the datasource, properties like connection info, max number of connections etc have to be configured in the server.xml or context.xml
    And here is the relevant documentation in tomcat on how to set up a datasource - http://jakarta.apache.org/tomcat/tomcat-5.5-doc/jndi-datasource-examples-howto.html
    Setting up a datasource in tomcat requires configuring them in server.xml (for global resources) or in context.xml (for a datasource resource local to your web application).
    Here is a thread which describes in detail the process of setting it up - http://forum.java.sun.com/thread.jspa?threadID=643344
    Now there are several issues setting up a tomcat datasource, especially for first time users. See the forum thread above for one such discussion.
    What configuration is required in tomcat when the stack trace so >clearly shows that he is using the sun.jdbc.odbc.JdbcOdbcDriver and >so obviously using a dsn name for his connection??????As I said earlier, you are missing the point. The OP is not trying to create a connection directly from his program. Or by datasource, he does not mean the microsoft user-dsn datasource that I think you are reffering to. Once again, please read the tomcat link above on what a jndi-jdbc datasource means
    Please give me the all 10 different issues that would produce the same stack trace.I was infact hoping somebody would ask. Just type the error stack trace in google, this forum or javaranch or theserverside.com and you would find tons of posts on setting up a jndi datasource and the issues people faced therein.
    that's the first and easiest suggestion to give. you don't need to give that suggestion here. Its an open forum. Nobody can tell anybody else on what he/she ought to post. If you dont like it, ignore it. But wait, that's an easy answer. And Iam not going to take that stand. I stick to my opinion that asking the OP to read the docs is still the best suggestion in the post. The OP's problems combined with his comments that the db is working fine suggest a serious lack of understanding of the way datasource and connection pooling works with tomcat.
    yes, if the problem is absolutely trivial like: how do i set up a connection using DriverManager - yes u can say - go read the docs. i can swear one can find the answers for half (or many more than that) problems posted in any forum in the documentation. but the fact is that many people do a fair amnount of hunting thru the docs and turn to a forum as a last resort. but they always miss something coz it's very natural. If you would search this forum and analyse duffy's or anybody else( who is a regular in this forum) previous posts, you would find that they have a pretty impeccable record of helping people with genuine problems when they know that the poster has taken some pains or effort to get it going by him/her self. They even hand hold people if the concept is a difficult one or if its one they find stiumlating/challenging.
    But this 'unable to set up a datsource' thinggy has been asked and answered a thousand times in this forum and many more in several other forums and all the OP had to do was just search. To be fair, the OP may not have been aware of this fact as he is coming up against this the first time, which's why I maintain, read the docs or search the forum is a suggestion that ought to be taken seriously (rather than being thought of as rude or condescending).
    If my comments seemed harsh, i apologize.Make that two. Its not my intention either to brow-beat or be harsh. I am just explaining why I took duffy's side, case in point. No offence intended.
    cheers,
    ram.
