无法在32位JVM上加载64位SWT库（替换SWT文件） [英] Cannot load 64-bit SWT libraries on 32-bit JVM ( replacing SWT file )

问题描述

我正在尝试调试此问题，但不知道在什么地方，我需要替换Eclipse的SWT jar 文件。

当前系统配置：

  Eclipse Helios 3.6  -  32 Bit 
 JDK 1.6 
 JVM  -  32位
 Windows 7  -  64位
  

错误消息：

  java.lang.UnsatisfiedLinkError：无法在32位JVM上加载64位SWT库

发生错误。查看日志文件
  

解决方法：

1. ：建议替代解决方案，但无法解决问题。

   
   
   

   仍然相同的错误




2. 我真的不想卸载32-JVM和32位Eclipse并安装相应的64位版本。

   
   
   

   不是选项

解决方法 paulsm4 和保罗·韦伯斯特回复& 我很困惑

当我尝试执行此操作来检查JVM时，Eclipse中的JRE版本

  package javaVersion; 
 
 public class JavaVersion 
 {
 
 public static void main（String [] args）
 {
 System.out.println（ JRE版本：+ System.getProperty（java.runtime.version））; 
 System.out.println（JVM位大小：+ System.getProperty（sun.arch.data.model））; 
 
} 
 
} 
  

输出： / p>

  1.6.0_31-b05 
 JVM位大小：32 
  pre> 
 
 
但是当我尝试使用JAVA的命令行 -  VERSION 
 
 
 
  
 
 
 
所以我的理解系统有64位JVM，Eclispe正在读32位JVM。那么我如何将系统转移到32位JVM？
解决方案
 Eclipse将在您启动时定义的任何JRE启动应用程序组态。由于您运行的是32位Eclipse，因此您正在运行/调试其32位SWT库，您需要运行32位JRE。
 
 
 
为了改变这一点，首先要确保你有一个32位的JRE配置已安装的JRE首选项。转到窗口 - >首选项，并导航到Java  - >已安装的JRE：
 
 
 
  
 
 
 
您可以单击添加并导航到您的32位JVM的 JAVA_HOME 添加它。
 
 
 
然后在运行配置中，找到您的Eclipse应用程序，并确保运行时JRE设置为您刚刚配置的32位JRE：

不要尝试替换可能会很差的SWT jar。
 
I'm trying to debug this problem but not sure where exactly i need to replace SWT jar file for Eclipse. 

Current System Config:
Eclipse Helios 3.6 - 32 Bit
JDK 1.6 
JVM - 32 Bit 
Windows 7 - 64 Bit

An error has occurred. See the log file
Workaround: 

Link1: Understood the cause of the problem and i tried to replace 64-bit SWT to 32 Bit but i'm not sure whether i'm doing it right ?

downloaded 32-bit file swt-3.6.1-win32-win32-x86.zip
 Extracted the zip file 
 Have files as shown below 



copied swt.jar file 
 navigated to C:\Program Files\eclipse\plugins
 removed 64-bit Swt file ( i.e org.eclipse.swt.win32.win32.x86_64.source_3.6.2.v3659c )
 placed copied swt.jar file and relaunched 

Still throws SAME ERROR 

also tried renaming the swt.jar file to org.eclipse.swt.win32.win32.x86_64.source_3.6.2.v3659c 

Still same ERROR
Link2: Suggested the alternative solution but couldn't resolve the problem. 

Still same ERROR 
I really don't want to uninstall 32-JVM and 32-Bit Eclipse and install corresponding 64 Bit versions. 

Not an OPTION 
Workaround After the paulsm4 and Paul Webster response & i'm confused 

When i tried executing this to check JVM, JRE version in Eclipse
package javaVersion;

public class JavaVersion
{

    public static void main( String[] args )
    {
        System.out.println( "JRE Version :" + System.getProperty( "java.runtime.version" ) );
        System.out.println( "JVM Bit size: " + System.getProperty( "sun.arch.data.model" ) );

    }

}
Output:
1.6.0_31-b05
JVM Bit size: 32
However when i tried on command line for JAVA - VERSION



So my understanding system has 64bit JVM where as Eclispe is reading 32 Bit JVM. So how can i divert system to read 32 Bit JVM ?
解决方案
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:



(Note the combobox that is poorly highlighted.)

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