Question

我有运行正常的MyCpu java类，我需要将输出显示到我尝试过仅使用JSP的网页中然后它不起作用然后我添加了JSTL标记库并添加了此代码-Djava.library .path =“。/ lib”到MANIFEST.MF 我也在使用Sigar API，然后我添加到库中，然后我以此错误结束：

java.lang.UnsatisfiedLinkError：org.hyperic.sigar.Sigar.getCpuInfoList（）[Lorg / hyperic / sigar / CpuInfo;

请提供任何帮助或建议？

package mydata;

import org.hyperic.sigar.CpuInfo;
import org.hyperic.sigar.Sigar;
import org.hyperic.sigar.SigarException;

public class MyCpu {
 private String cpuInfoList;
 public String getCpuInfoList(){
    return this.cpuInfoList;
    }
public MyCpu() {
Sigar sigar = new Sigar();
String output = " ";
CpuInfo[] cpuInfoList = null;
try {

cpuInfoList = sigar.getCpuInfoList();
} catch (SigarException e) {
e.printStackTrace();
return;
}
for (CpuInfo info : cpuInfoList) {
output += "Vendor: " + info.getVendor() + "\n";
output += "Model: " + info.getModel() + "";
output += "DD:" +info.toString()+ "";
}
System.out.println(output);
}
public static void main(String[] args) {
MyCpu main = new MyCpu();
}
}

尝试将其添加为JVM参数

    -Djava.library.path="./lib"

使用JSTL库标记调用Java类表单JSP
