问题描述：

I'm trying to debug this problem but not sure where exactly i need to replace SWT jar file for Eclipse.

Current System Config:

EclipseHelios3.6-32Bit JDK 1.6 JVM -32BitWindows7-64Bit

Error Message:

java.lang.UnsatisfiedLinkError:Cannot load 64-bit SWT libraries on 32-bit JVM at org.eclipse.swt.internal.Library.loadLibrary(Library.java:194) at org.eclipse.swt.internal.Library.loadLibrary(Library.java:174) at org.eclipse.swt.internal.C.<clinit>(C.java:21) at org.eclipse.swt.widgets.Display.<clinit>(Display.java:138) at org.eclipse.ui.internal.Workbench.createDisplay(Workbench.java:687) at org.eclipse.ui.PlatformUI.createDisplay(PlatformUI.java:161) at de.vogella.rcp.intro.first.Application.start(Application.java:18) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:196) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:110) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:79) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:369) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:179) at sun.reflect.NativeMethodAccessorImpl.invoke0(NativeMethod) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:620) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:575) at org.eclipse.equinox.launcher.Main.run(Main.java:1408) at org.eclipse.equinox.launcher.Main.main(Main.java:1384)An error has occurred.See the log file


解决方法：

Eclipse is launching your application with whatever JRE you defined in your launch configuration.  Since you're running the 32-bit Eclipse, you're running/debugging against its 32-bit SWT libraries, and you'll need to run a 32-bit JRE.

Your 64-bit JRE is, for whatever reason, your default Installed JRE.

To change this, first make sure you have a 32-bit JRE configured in the Installed JREs preference.  Go to Window -> Preferences and navigate to Java -> Installed JREs:

You can click Add and navigate to your 32-bit JVM's JAVA_HOME to add it.

Then in your Run Configuration, find your Eclipse Application and make sure the Runtime JRE is set to the 32-bit JRE you just configured:

Don't try replacing SWT jars, that will likely end poorly.
