Import org.eclipse.....

I've downloaded source code of one software and i've tried to compile and run it.
But it doesn't work...the error is in the part of import said that "import org.eclipse cannot be resolved"
some parts of code are
import org.eclipse.swt.custom.StyledText;
import org.eclipse.swt.events.PaintEvent;
import org.eclipse.swt.graphics.Color;
import org.eclipse.swt.graphics.GC;
import org.eclipse.swt.graphics.Point;
Does anyone have any suggestion how to solve this problem?
I've also downloaded org.eclipse.swt.win32.win32.x86_3.3.0.v3346.jar but i don't know how to add it into the eclipse to make it works.
Thanks

In your project explorer rightclick your project, from the context menu select Build Path -> Add external Jar. In the dialog select the jar file you want to add.

  • Import org.eclipse.persistence.sessions.Project ?

    Hello,
    I have a legacy mapping file that is a Java file and its class extends org.eclipse.persistence.sessions.Project.
    This file maintains the toplink mapping and is the only toplink configuration of the project. During its inception, the webgain workbench was used to create the file. Later, it was totally hand maintained.
    Now, we would like to bring this to be managed in the JDeveloper Toplink workbench.
    Could you please tell if this is possible.
    Thanks,
    Raj

    Username and password supplied in the persistence.xml file should be for the Database configured user. This user is not an OS user.

    Alright, I'll try to keep it as simple as possible. If that's not going to work out, we can always complicate it later :)
    I suppose you had a look at the link and I assume you know about threads.
    We can easily fix this issue if you are instantiating, calling and disposing the object within one thread, e.g. you use it only in one method like
    public mySwtExecutionMethod(String fileName){
      WordSearchReplace replace = new WordSearchReplace();
      // do your replacing here
      replace.dispose();
      // no reference to replace is left so it won't escape this thread
    }Now the fix for your class becomes simple. As you remember from the link, you have to call all methods from within the UI thread. We will now create a Display every time upon instantiation of WordSearchReplace, so the current thread becomes the UI thread.
    I had a look at the constructor, and the overhead doesn't seem that bad, provided this is not a dedicated search&replace server.
    private final Display display;
    public WordSearchReplace()
         display = new Display(); // create display
         this.shell = new Shell(display);   // initialize shell with new display so this thread becomes the UI thread
         this.frame = new OleFrame(this.shell, SWT.NONE);
         this.wordSite = new OleClientSite(this.frame, SWT.NONE, WordSearchReplace.PROG_ID);
         this.wordAutomation = new OleAutomation(this.wordSite);
    }Since we always create a new Display, we should also dispose it. There is already a dispose() method, so we just have to add to it
    display.dispose();That's it!
    If you hold on longer to your reference and this isn't working for you, you'd have to do a lot more synchronizing and that the UI thread still exist as long as the reference.
    Wish you good luck

  • Import org.apache.avalon cannot be resolved

    Hi, I am new to Eclipse and J2EE in general and I have tried to import a project in Eclipse 3.0.1. However, I am getting several compile errors having to do with the following imports:
    import org.apache.avalon.framework.activity.Initializable;
    import org.apache.avalon.framework.activity.Startable;
    import org.apache.avalon.framework.configuration.Configurable;

    import dragon.common.services.cache.store.IStoreComponent;
    stating that
    "The import..." [import package name] "...cannot be resolved"
    Can anyone help with what I should do? Thanx

    I am trying to compile code but keep getting an error stating that the import of a class is not working? I wondered if I am having the same problem. I am running eclipse 3.0. The applet is called joole and it is importing CBoolFkt but it is evidently not working. Appreciate any ideas.
    The applet is not initiating and the error messages is as follows:
    java.lang.Error: Unresolved compilation problems:

  • The import org.apache cannot be resolved

    Hi All,
    I am a Java\Eclipse newbie. I am trying to import the org.apache.xerces package, and the import is failing with this error:The import org.apache cannot be resolved
    I am not using Maven\Ant for building the project. I know I need to download some class files\jar files to get this to work, but I am not sure where to download these packages from. Could someone please help me out here?
    import org.w3c.dom.Node;
    import org.apache.xerces.parsers.DOMParser;
    import org.apache.xerces.dom.traversal.TreeWalkerImpl;
    import org.apache.xerces.domx.traversal.NodeFilter;
    import org.apache.xerces.dom.DocumentImpl;
    THanks a lot!

    Well, if you are in fact looking to download the JARs for the Apache Xerces project, you should be able to find them at the Apache Xerces project page.
    If you already have the JARs downloaded, you need to make sure that they appear on your CLASSPATH, otherwise your application will never find them. Since you are using an IDE, this should be as easy as adding the JARs to your project.

    Not sure what netweaver is, but it looks like you are missing the latest JST package that contains support for Apache 5.5. Try updating your Eclipse install and get the latest compatible JST.

    It probably depends on which tool are you using to generate EJB's from tables, but i don't think it's possible to make it use String for INTERVAL fields.
    I don't have much experience with working with INTERVAL fields but my guess is that they are converted to Lob's instead of byte array (Lob actually make sense as a representation of byte array). My other guess is that if you choose String for your field then when read from DB it is first converted to Lob then to String, but proper mapping for INTERVAL field is Lob. Number field can be converted to String but its not a "proper" way to handle Number fields.

  • Import org.mozilla.javascript.Context; !!ERROR This import cannot be resol.

    Hello to All,
    I am attempting to use an open source program for speech recognition and several "training" files for the program have a number of
    import org.mozilla.javascript.Context;imports that bring the error "This import cannot be resolved"
    I know for an import to work it must be part of the "package" or "API" from Sun.
    I am using javasdk1.5.0, Eclipse 3.1 and Ant.
    So, What do I have to do to actually "import the org.mozilla.javascript"????
    This must be a very simple answer but I have not had much understanding here.
    Thanks for the help!
    Chetanji
    Edited by: Chetanji on May 4, 2008 11:28 AM

    Thanks tschodt,
    That would have been the answer, except I did some more googling right after my question was asked and found that I needed the js.jar.
    I looked in the jsapi.jar and found it was already there.
    So I built it and much of the "red" disappeared from the project in Eclipse.
    I know now I must reorganize the project, as the imports are calling for files that cannot be found, that happen to be elsewhere or not in the build path.
    Bringing Unix/Linux OpenSource into Windows is usually tricky, but well worth the investment in time spent.
    I give you the Duke as you were correct and the only one to answer.
    Blessings,

  • The import org.apache cannot be resolved and I am not sure why?

    Alright, so I decided to build myself the simplest of simplest ftp client so that I could understand how this works:
    Ok, I have parts built but I am trying to include the following things:
    import org.apache.commons.net.ftp.FTPClient;
    import org.apache.commons.net.ftp.FTPFile;The error I am getting from eclipse (which is the editor that I am using) is:
    The import org.apache cannot be resolvedThe same thing happens when I try to do:
    import com.jscape.inet.ftp.*;I have an idea what is going on with this but I am not entirely sure. I think I need a package that I must download from apache or somewhere that might give me access to libraries?
    I would be grateful to any help...
    Thanks,

    Yes you need to have the classes that you want to import. If you have them then you need to add them to your project's classpath.

    You can try asking third party API questions here, but you'll likely be waiting a long time. You are better off looking for a forum that is specifically for your third party technology; in this case I would look around on the Eclipse website since its their tech.
