Java Forum / General / April 2006eclipse questions
Hi I am new to eclipse, how can i do the followings? 1) In borland, i can create a execute jar, or a native execute (.exe), in esclipse, i found the way to create an execute but not native exe, how to? 2) Esclipse can export an execute jar but how to rebuild that execute jar? i can export it again, but it is stupid because i have to press several buttons. In jbuilder, after i press the "build" button, i can make it. 3) If i open the .project file, it will not open the project. So how to open a project which is not in your workspace? thanks a lot!! from Peter (cmk128@hotmail.com) Hi Peter, > Hi > I am new to eclipse, how can i do the followings? > 1) In borland, i can create a execute jar, or a native execute (.exe), > in esclipse, i found the way to create an execute but not native exe, > how to?

(I admit that setting this up/configuring this is also hard to do...) > 3) If i open the .project file, it will not open the project. So how to > open a project which is not in your workspace? The same: impossible. (Of course: AFAIK!) Ciao, Ingo >> create a execute jar ... or a native execute (.exe) > Impossible. (Perhaps with some commercial/expensive plugin?) Ant exec task, or custom task. Eclipse's built-in runner can only run Java apps. "External Tools" can run ant, and this is meant for integrating builders. Eclipse is not a general-purpose shell. If you want to run a windows binary, double click on it in an explorer window... >> how to rebuild that execute jar? File -> Export -> Jar File -> "Export generated class files and resources" is checked -> select your Main class What could be easier? Or the Ant way: Ant jar task <attribute name="Main-Class" .../> >>So how to open a project which is not in your workspace? File->New->Project->Java Project->"Create project from existing source." It's better to put your existing project in your workspace dir, and then New Project as though you are creating it -- Eclipse will find it during that dialog. Eclipse really works quite differently from JBuilder, especially in terms of how it manages the workspace. The view and the model of the workspace are distinct. >>> how to rebuild that execute jar? > > File -> Export -> Jar File -> "Export generated class files and > resources" is checked -> select your Main class > > What could be easier? As the OP said, "click build" would be easier. - Oliver > As the OP said, "click build" would be easier. After the first time you tell Eclipse what you want, you just click the JarDesc file and it's one step. If the purpose of this thread is to praise the superiority of JBuilder to Eclipse, I'm not going to respond to it. Been there, done that, and (literally) have the t-shirt.

Thanks james the jar description file really work. cmk128@hotmail.com schrieb: > 2) Esclipse can export an execute jar but how to rebuild that execute > jar? i can export it again, but it is stupid because i have to press > several buttons. You can create a "jardesc" file somewhere in the jar exporter. If you right-click on the jardesc, the context menu will allow you to rebuild the jar. Or use ant to automatically build the jar, as Ingo suggests. Timo > Or use ant to automatically build the jar, as Ingo suggests. It's much easier than that. Just right click on your project and export jar. Be sure to check "Export generated class files" and then you'll be able to browse to the main Class to execute. I'm not sure, but I think there also might be a way to save that operation as an ant task when you do it from the wizard as well.

Peter said that he knew this, but it is no option for him: "i can export it again, but it is stupid because i have to press several buttons. In jbuilder, after i press the "build" button, i can make it." BTW: As for your other post: >>>create a execute jar ... or a native execute (.exe) >> [quoted text clipped - 4 lines] > Eclipse's built-in runner can only run Java apps.... > If you want to run a windows binary, I think, you misunderstood Peter here: He did not want to start an executable from Eclispe, but he said that he wants to create an executable from Eclipse. (And I think, that my answer to that ("Impossible...") is correct.) Ciao, Ingo > Peter said that he knew this, but it is no option for him: There's a language barrier at work, and I apologize for misunderstanding. You can save the JAR Description at the end of that wizard dialog, and then all you have to do is click that description file, "Create Jar", and voila. Not only "possible", but extremely easy, a single click, and a confirmation to overwrite if the file exists. Still, I prefer Ant. A newbie to Eclipse might need to be shown the "Ant View". What was the other thing you said was impossible?

And how is this solution different from the one I posted 4 hours ago? > I think, you misunderstood Peter here: He did not want to start an > executable from Eclispe, but he said that he wants to create an > executable from Eclipse. (And I think, that my answer to that > ("Impossible...") is correct.) How does JBuilder do it? AOT or wrapper? I'm guessing it does nothing more than wrap a call to the java runtime against a jar that's stored as data in the executable file. I know that JET does a good job of AOT. I'm sure whatever AOT or runtime wrapper you'd care to use could be deployed as an ant task. Hopefully, this is one of the last steps in the OP's project, and by the time he gets there he won't be an Eclipse newbie anymore :-) Maybe he will even see the questionable wisdom of making "exe's" from Java, and will discover JWS, or merely realize that Windows can "run .jars" without much help. therer is a "native executable builder" in jbuilder, it can create native exe in windows platform. cmk128@hotmail.com schreef: > Hi > I am new to eclipse, how can i do the followings?

Apart from the useful answers you already got, I want to add that there is a dedicated newsgroup for Eclipse beginners: news://news.eclipse.org:119/eclipse.newcomer HTH, H. - -- Hendrik Maryns ================== www.lieverleven.be http://aouw.org cmk128@hotmail.com schrieb: > 2) Esclipse can export an execute jar but how to rebuild that execute > jar? i can export it again, but it is stupid because i have to press > several buttons.

You can try the Fat-Jar Eclipse Plugin http://fjep.sourceforge.net/ It has a quick-build option (Right-Click on the java-project and select the Menu Quick-Build. The Eclipse exporter can not handle referenced jars. Fat-Jar supports the one-jar http://one-jar.sourceforge.net/ option to include jars in jars. Another option supported by jbuilder is to include only needed files into the jar. The beta-preview of Fat-Jar includes Auto-Jar http://autojar.sourceforge.net/ Best regards, feri Free MagazinesGet these publications absolutely FREE for up to 12 months.
