我从applet通过Java Native Interface调用动态库文件(Visual C ++)。问题是即使我处理try / catch错误处理我也无法在" Java控制台"中看到异常细节。我可以从哪里得到错误详情吗?我确信它必须是日志文件中的某个位置。
下面是代码。
import java.security.AccessController;
import java.security.PrivilegedAction;
public class TempletGenerator {
static {
try
{
AccessController.doPrivileged(new PrivilegedAction()
{
public Object run()
{
try
{
System.out.println("Loading.. TempletGen");
System.out.println("java.library.path=="+System.getProperty("java.library.path"));
// privileged code goes here, for example:
System.loadLibrary("SourceAFIS");
System.loadLibrary("TempSample");
System.loadLibrary("TempletGen");
System.out.println("Successfully loaded TempletGen");
return null; // nothing to return
}
catch (Exception e)
{
System.out.println("Error "+e.getMessage());
e.printStackTrace();
return null;
}
}
});
}
catch (Exception e)
{
System.out.println("Error "+e.getMessage());
e.printStackTrace();
}
}
public native String getTemplate(byte[] byteArray, String name);
public String getTempletData(byte[] byteArray, String name){
try{
System.out.println("TempletGenerator.getTempletData");
TempletGenerator tg = new TempletGenerator();
return tg.getTemplate(byteArray, name);
}catch(Exception e){
System.out.println("Error details ......." + e.getMessage());
}
return "";
}
}
提前致谢!
