我正在尝试使用twitter4j库为我的java项目发送推文.在我第一次运行时,我收到了关于证书sun.security.validator.ValidatorException和错误的错误sun.security.provider.certpath.SunCertPathBuilderException.然后我添加了twitter证书:
C:\Program Files\Java\jdk1.7.0_45\jre\lib\security>keytool -importcert -trustcacerts -file PathToCert -alias ca_alias -keystore "C:\Program Files\Java\jdk1.7.0_45\jre\lib\security\cacerts"
但没有成功.这是获得twitters的过程:
public static void main(String[] args) throws TwitterException {
ConfigurationBuilder cb = new ConfigurationBuilder();
cb.setDebugEnabled(true)
.setOAuthConsumerKey("myConsumerKey")
.setOAuthConsumerSecret("myConsumerSecret")
.setOAuthAccessToken("myAccessToken")
.setOAuthAccessTokenSecret("myAccessTokenSecret");
TwitterFactory tf = new TwitterFactory(cb.build());
Twitter twitter = tf.getInstance();
try {
Query query = new Query("iphone");
QueryResult result;
result = twitter.search(query);
System.out.println("Total amount of tweets: " + result.getTweets().size());
List<Status> tweets = result.getTweets();
for (Status tweet : tweets) {
System.out.println("@" + tweet.getUser().getScreenName() + " …我有一个Java客户端试图访问带有自签名证书的服务器.
当我尝试发布到服务器时,我收到以下错误:
无法找到所请求目标的有效证书路径
在对这个问题进行了一些研究之后,我做了以下工作.
root.cer文件.keytool -import -alias example -keystore cacerts -file root.cerkeytool -list -v -keystore cacerts我仍然得到同样的错误.
我有一种感觉这是因为我的Glassfish实际上并没有阅读我修改过的cacert文件,但可能还有其他一些.
你们有没有遇到过这个问题,能否把我推向正确的方向？
我的java程序如何知道包含证书的密钥库在哪里？或者,我如何告诉我的java程序在哪里查找密钥库？
以某种方式指定密钥库后,如何指定用于向客户端验证服务器的证书？
我一直在研究从动态Web应用程序中提取信息的程序,该程序运行正常,直到我将我的tomcat服务器设置为使用自签名(因此,不受信任)证书使用SSL.错误的堆栈跟踪是:

int portSmtps = greenmail.getSmtps().getPort();
System.out.println("Smtps started on port:" + portSmtps); …我有个问题.已经挣扎了很长时间.这是我的代码:
package com.XYZ.spr.server;
import org.apache.commons.mail.Email;
import org.apache.commons.mail.SimpleEmail;
public class GeneratorMaili {
public static final String HOSTNAME = "smtp.XYZ.com";
public static final String ADDRESS_FROM = "user@XYZ.com";
public static final String TOPIC= "Topic";
public static void wyslijEmail(String reciver) throws Exception {

System.setProperty("javax.net.ssl.trustStorePassword", "changeit");
Email email = new SimpleEmail();
email.setSmtpPort(587);
// email.setTLS(true);
email.setSSL(true);
System.out.println("fdfdf");
email.setAuthentication("user@.XYZ.pl", "pass");

email.setMsg("Test");
email.addTo(reciver);
System.out.println(reciver);
email.send();
System.out.println("Ok!");
}
}
我的证书有问题.以下是我所做的步骤:
我写了一个java客户端通过ssl连接到Ldap。我将 CA 证书导入到我的 java 密钥库中，并且能够通过 ssl 连接 Ldap 并提取信息。问题是它并不总是有效。通常它会抛出：CommunicationException:sun.security.validator.ValidatorException: PKIX path building failed。如果我再次运行（没有改变任何东西），它就可以工作。
这个问题让我死了好几天，作为一种解决方法，我正在捕获这个异常并重试。但我正在寻找永久修复。任何帮助将不胜感激。
下面是我获取上下文的代码：
Hashtable<String, String> env = new Hashtable<String, String>();
env.put(Context.INITIAL_CONTEXT_FACTORY,

env.put(Context.SECURITY_PRINCIPAL, securityPrincipal);
env.put(Context.PROVIDER_URL, url);
env.put(Context.SECURITY_CREDENTIALS, securityCredential);
env.put("java.naming.provider.url", url);
return new InitialLdapContext(env, null);
