hi
I need to use the glpk jar in org.xtext.example.mydsl.ui.popup.actions.NewAction
package org.xtext.example.mydsl.ui.popup.actions;
import org.eclipse.jface.action.IAction;
import org.eclipse.jface.dialogs.MessageDialog;
import org.eclipse.jface.viewers.ISelection;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.ui.IObjectActionDelegate;
import org.eclipse.ui.IWorkbenchPart;
import org.gnu.glpk.GlpkSolver;
public class NewAction implements IObjectActionDelegate {
private Shell shell;
/**
* Constructor for Action1.
*/
public NewAction() {
super();
}
/**
* @see IObjectActionDelegate#setActivePart(IAction, IWorkbenchPart)
*/
public void setActivePart(IAction action, IWorkbenchPart targetPart) {
shell = targetPart.getSite().getShell();
}
/**
* @see IActionDelegate#run(IAction)
*/
public void run(IAction action) {
GlpkSolver glp = new GlpkSolver();
MessageDialog.openInformation(
shell,
"org.xtext.example.mydsl.ui",
"New Action was executed.");
}
/**
* @see IActionDelegate#selectionChanged(IAction, ISelection)
*/
public void selectionChanged(IAction action, ISelection selection) {
}
}
I tried all ways to add jar, described here:
wikihow.com/Add-JARs-to-Project-Build-Paths-in-Eclipse-(Java)
but when I run the command, I have this exception :
