java 使用JNative 调用 dll 问题~ 在线等
我用java jnative调用dll, 前面几个接口都是使用正常的.
但是有个接口调用过之后,会抛个异常,如下:
An unrecoverable stack overflow has occurred.
#
# An unexpected error has been detected by HotSpot Virtual Machine:
#
# EXCEPTION_STACK_OVERFLOW (0xc00000fd) at pc=0x0da1db27, pid=444, tid=580
#
# Java VM: Java HotSpot(TM) Client VM (1.5.0-b64 mixed mode, sharing)
# Problematic frame:
# C [VodCltApi.dll+0x1db27]
#
# An error report file with more information is saved as hs_err_pid444.log
#
# If you would like to submit a bug report, please visit:
# http://java.sun.com/webapps/bugreport/crash.jsp
========= 但是这个接口我用VC调用是正常的.不知道是哪里出了问题.

这里说明是你的c代码执行导致crash，一般就是从java向c函数传参数错误，导致执行的c代码出现问题。最好贴出你的java代码和c代码，以及传的参数是什么。
[解决办法]
java 代码：
JNative sftpUtil = null;
try{
sftpUtil = new JNative("sftp_p2p.dll", "sftp_p2p_client");
sftpUtil.setRetVal(retVal);
//for(int i=0;i<args.length;i++){
//DllType type = args[i];
//System.out.println(type.getValue().toString());
//sftpUtil.setParameter(i, type.getType(), type.getValue()+"");
//}
String ret_msg = "返回信息";
String path="C:\\dzbk\\sended\\201105";
String pathFile="FFO365_00180005_19200000_00180005_0001.20110526";
String ip="22.36.2.18";
Integer port=1777;
String userid="00180004";
String password="12345678";
sftpUtil.setParameter(0,Type.STRING, path);
sftpUtil.setParameter(1,Type.STRING, pathFile);
sftpUtil.setParameter(2,Type.STRING, ip);
sftpUtil.setParameter(3,port);
sftpUtil.setParameter(4, Type.STRING,userid);
sftpUtil.setParameter(5, Type.STRING,password);
sftpUtil.setParameter(6, Type.STRING,ret_msg);
Pointer a = new Pointer(MemoryBlockFactory.createMemoryBlock(500));
sftpUtil.setParameter(7, a );
sftpUtil.invoke();
return sftpUtil.getRetVal();
}catch(Exception e){
throw e;
}finally{
if (sftpUtil != null){
try{
sftpUtil.dispose();
}catch (Exception e){
}
}
}
====================================
sftp_p2p.dll 已放在C:\WINDOWS\system32
sftp_p2p.dll提供的方法是sftp_p2p_client
FUNCTION integer sftp_p2p_client( ref string file_path,&
ref string file_name,&
ref string peer_addr, &
integer peer_port,&
ref string uid, &
ref string passwd, &
ref string ret_msg )
[解决办法]
应该是传参数的问题，dll中接受的应该是指针吧，而你直接传的是string类型。
