Import

[pat270881]

Hello,

I develop java programs with eclipse and now I have to use some packages of symantec. I already downloaded the jar.zip and extracted it in the plugins folder of the eclipse directory. But can anybody explain me how I can use these packages in the eclipse environment? - What actions I have to do etc.?

Thanks in Advance.

Regards

patrick

hey pat,

are there anne .jar archives in the zip file? if yes, extract them to a folder.

then you have to add the extracted jar/zip file to your project.

open the properties of your project, go to "java build path", go to the "library"-tab and click "import external jars". then select the zip/jar file.

in your programm, you have to import the classes with

import this.is.the.class.in.the.jar.file

Hello,

Thank you very much now it works. But unfortunately one more problem occured. I need to use JFrames, JTextArea, JScrollPane, etc. in my application. How and from where can I import the corresponding jar file to use this elements? - I search with google after that but I haven't found anything useful.

thanks

You don't need a jar file, its just the Swing package:

import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTextArea;

you should think about using an IDE that organizes your imports for you. :wink:

But the problem is that the application uses an import statement something like this:

import com.sun.java.swing.JFrame;

and when I compile the application an error occurs, that it is not possible to resolve this statement.

Have you got any advice?

Which java-version is the app. you downloaded?

Acutally I don't know what that import[...] is supposed to mean, but do as Wildcard said. You are also able to import every class from swing by writing

import javax.swing.*;

Hello,

The problem is that I do not know what java version this is. We got this application in the context of a lecture at school. The application has some mistakes and we have to fix these errors to get the application running again without problems. This application uses the previous mentioned package and I do not know from where I can get this package...?

The classes like com.sun.java.swing.JFrame does exists. I read about it here
http://euler.aero.iitb.ac.in/docs/P.../swing/JScrollPane.AccessibleJScrollPane.html

The problem is I do not know where I can get the corresponding package to use these classes. Have you got any further help?

Normally eclipse detects where your java is and which version you have. The JFrame, J... classes are in the standard JRE. So you do not have to do anything else.

import javax.swing.JFrame;
import javax.swing.JButton;

If you cannot use these imports, check if eclipse has found a correct java version. (Window->Preferences->Java->Installed JREs)
Maybe just try the "search"-button.

Maybe one of the Problems you have to fix
Try to remove those import statements and press ctrl+shift+o to organize your imports.
