linux-weblogic下调用webservice服务时报java.net.SocketException: Broken pipe，如何解决

服务器的网络环境呢？估计跟防火墙之类有关
另外，WS不适合批量调用，可以的话，至少改成多笔数据放在一批里面处理

如何实现WebService与Socket通信

WebService
-基于-
HTTP
-基于-
TCP
而socket是TCP的应用。
socket开发的东西可以很简单的兼容所有HTTP请求：包括长/短连接。
而HTTP是短连接的。
所以socket应用程序需要做调整，改一下解析包文的处理机制即可。WebService
只不过是些xml格式的报文，也叫soap.
对于精通网络编程（socket）的人来说这一点都不难，希望你能找到开发这个socket程序的人
让他修改一下代码即可。

调用webservice 出现error writing to socket错误

您好,请在代码调用写入前判定当前网络是否还正常连接即可.
您的网络已经断开连接了.
此种错误如果是单纯的API调用webservice的话..基本是无法解决的.可以尝试重试连接这个方法

webservice上面的socket通信

WebService好像搞不了Socket通信的吧 WebService本来就是通信的

JAVA怎样调用https类型的webservice

第二步就是介绍怎样生成证书，先写一个InstallCert.java类放到自己电脑的D盘根目录下，（注意这个类是没有包名的）类中代码如下：
/**

import java.io.BufferedReader;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.InputStreamReader;

import javax.net.ssl.SSLSocketFactory;
import javax.net.ssl.TrustManager;
import javax.net.ssl.TrustManagerFactory;
import javax.net.ssl.X509TrustManager;
public class InstallCert {
public static void main(String args) throws Exception {
String host;
int port;
char passphrase;
if ((args.length == 1) || (args.length == 2)) {
String.split(":");
host = c;
port = (c.length == 1) ? 443 : Integer.parseInt(c);
String p = (args.length == 1) ? "changeit" : args;
passphrase = p.toCharArray();
} else {
System.out
.println("Usage: java InstallCert 《host》");
return;
}

File file = new File("jssecacerts");
if (file.isFile() == false) {
char SEP = File.separatorChar;
File dir = new File(System.getProperty("java.home") + SEP + "lib"
+ SEP + "security");
file = new File(dir, "jssecacerts");
if (file.isFile() == false) {
file = new File(dir, "cacerts");
}
}
System.out.println("Loading KeyStore " + file + "...");
InputStream in = new FileInputStream(file);
KeyStore ks = KeyStore.getInstance(KeyStore.getDefaultType());
ks.load(in, passphrase);
in.close();

SSLContext context = SSLContext.getInstance("TLS");
TrustManagerFactory tmf = TrustManagerFactory
.getInstance(TrustManagerFactory.getDefaultAlgorithm());
tmf.init(ks);
X509TrustManager defaultTrustManager = (X509TrustManager) tmf
.getTrustManagers();
SavingTrustManager tm = new SavingTrustManager(defaultTrustManager);
context.init(null, new TrustManager { tm }, null);
SSLSocketFactory factory = context.getSocketFactory();

System.out
.println("Opening connection to " + host + ":" + port + "...");
SSLSocket socket = (SSLSocket) factory.createSocket(host, port);
socket.setSoTimeout(10000);
try {
System.out.println("Starting SSL handshake...");
socket.startHandshake();
socket.close();
System.out.println();
System.out.println("No errors, certificate is already trusted");
} catch (SSLException e) {
System.out.println();
e.printStackTrace(System.out);
}

X509Certificate chain = tm.chain;
if (chain == null) {
System.out.println("Could not obtain server certificate chain");
return;
}

BufferedReader reader = new BufferedReader(new InputStreamReader(
System.in));

System.out.println();
System.out.println("Server sent " + chain.length + " certificate(s):");
System.out.println();
MessageDigest sha1 = MessageDigest.getInstance("SHA1");
MessageDigest md5 = MessageDigest.getInstance("MD5");
for (int i = 0; i 《 chain.length; i++) {
X509Certificate cert = chain;
System.out.println(" " + (i + 1) + " Subject "
+ cert.getSubjectDN());
System.out.println(" Issuer " + cert.getIssuerDN());
sha1.update(cert.getEncoded());
System.out.println(" sha1 " + toHexString(sha1.digest()));
md5.update(cert.getEncoded());
System.out.println(" md5 " + toHexString(md5.digest()));
System.out.println();
}

System.out
.println("Enter certificate to add to trusted keystore or ’q’ to quit: ");
String line = reader.readLine().trim();
int k;
try {
k = (line.length() == 0) ? 0 : Integer.parseInt(line) - 1;
} catch (NumberFormatException e) {
System.out.println("KeyStore not changed");
return;
}

X509Certificate cert = chain;
String alias = host + "-" + (k + 1);
ks.setCertificateEntry(alias, cert);

OutputStream out = new FileOutputStream("jssecacerts");
ks.store(out, passphrase);
out.close();

System.out.println();
System.out.println(cert);
System.out.println();
System.out
.println("Added certificate to keystore ’jssecacerts’ using alias ’"
+ alias + "’");
}

private static final char HEXDIGITS = "0123456789abcdef".toCharArray();

private static String toHexString(byte bytes) {
StringBuilder sb = new StringBuilder(bytes.length * 3);
for (int b : bytes) {
b &= 0xff;
sb.append(HEXDIGITS);
sb.append(HEXDIGITS);
sb.append(’ ’);
}
return sb.toString();
}

private static class SavingTrustManager implements X509TrustManager {

private final X509TrustManager tm;
private X509Certificate chain;

SavingTrustManager(X509TrustManager tm) {
this.tm = tm;
}

public X509Certificate getAcceptedIssuers() {
throw new UnsupportedOperationException();
}

public void checkClientTrusted(X509Certificate chain, String authType)
throws CertificateException {
throw new UnsupportedOperationException();
}

public void checkServerTrusted(X509Certificate chain, String authType)
throws CertificateException {
this.chain = chain;
tm.checkServerTrusted(chain, authType);
}
}

}
将上面的InstallCert.java编译成InstallCert.class文件放到自己电脑的D盘根目录下。这是正常的情况下D盘根目录下会有3个文件，如下图：
打开cmd进入到d盘开始执行生成证书命令，我这里不便于那我的网址测试我用支付宝的网址来测试的，输入：java InstallCert www.alipay.com 如下图
当出现了：Enter certificate to add to trusted keystore or ’q’ to quit:
这行代码时，输入1，回车。正常执行完后在D盘根目录下就会出现证书“jssecacerts”文件，具体如下图：
6
得到证书后将证书拷贝到$JAVA_HOME/jre/lib/security目录下，我这里是win7系统，在尝试的过程中需要将证书重命名为：cacerts 放进去才会有用。（这个步骤在不同的环境和操作系统下有点不同，需要注意）

怎么在c语言中用socket的方式调用webservice

可以实现，先connect
sockaddr_in server;
if (m_bSockConnected)
{
return TRUE;
}
server.sin_addr.s_addr= inet_addr(m_szHost);
server.sin_family= AF_INET;
server.sin_port= htons((UINT)m_nPort);
if(connect(m_socket, (struct sockaddr*)&server, sizeof(server)) == SOCKET_ERROR)
{
m_bSockConnected = FALSE;
m_nLastErrorNo = WSAGetLastError();
MessageBox(0, "请检网络和服务器", "网络连接错误", 0);
return FALSE;
}
else
{
m_bSockConnected = TRUE;
}
int timeout=30;
setsockopt(m_socket, SOL_SOCKET, SO_RCVTIMEO, (const char*)&timeout, sizeof(int));
然后再发送url
char requestHeader= {0};
char nBuf= {0};
strcpy(requestHeader, "PUT ");
strcat(requestHeader, szUrl);
strcat(requestHeader, "&Content-Length=");
_ui64toa(contentLength + 8, nBuf,10); //额外加了传输完成头的长度是8 strlen(SEND_END_STRING)
strcat(requestHeader, nBuf);
strcat(requestHeader, "&FileCount=");
ltoa(fileCount,nBuf, 10);
strcat(requestHeader, nBuf);
strcat(requestHeader," HTTP/1.1\r\nContent-Length: ");
_ui64toa(contentLength + 8, nBuf, 10);
strcat(requestHeader,nBuf);
strcat(requestHeader,"\r\nHost: ");
strcat(requestHeader,m_szHost);
strcat(requestHeader,":");
itoa(m_nPort,nBuf,10);
strcat(requestHeader,nBuf);
strcat(requestHeader,"\r\nAccept: */*;\r\nAccept-Encoding: gzip,deflate\r\nKeep-Alive: 60000\r\nConnection: keep-alive\r\n\r\n");
//MessageBox(0, requestHeader, "info", 0);
char * szUTF8 = NULL;
BOOLbRet = FALSE;
bRet = CCharTransLib::EncodeToUTF8(requestHeader,&szUTF8);
if (bRet)
{
if ( (int)strlen(szUTF8) != send(m_socket, szUTF8, strlen(szUTF8), 0))
{
m_nLastErrorNo = GetLastError();
bRet = FALSE;
}
if (szUTF8)
{
delete szUTF8;
szUTF8 = NULL;
}
}
以上是从我工程里面摘的，可能有些变量楼主编译不过去，但基本思想就是这样的

socket 和 webservice 的区别和比较

webservice 有一个 socket 难以比拟的优势：
webservice基于HTTP协议，是无状态的，因此可以例如现有非常成熟的Web集群来提供高负载，同比之下 socket 就非常难。
socket其实也可以无状态，连一下就断开.
webservice就是这么做的。
