java - 调用Rest Web Service时没有这样的算法

我有这段代码直接处理来自REST客户端的响应:

 uc = (HttpURLConnection) u.openConnection();
 uc.setConnectTimeout(2000);
 uc.setDoOutput(true);

 out = new OutputStreamWriter(uc.getOutputStream());
 out.write(posturl);
 out.flush();
 rd = new BufferedReader(new InputStreamReader(uc.getInputStream()));

当我运行此代码时(实际上是一个罐子，在OpenESB中运行一个BPEL)，出现以下异常:

java.security.NoSuchAlgorithmException: Error constructing implementation (algorithm: Default, provider: SunJSSE, class: sun.security.ssl.SSLContextImpl$DefaultSSLContext) cause java.security.NoSuchAlgorithmException: Error constructing implementation (algorithm: Default, provider: SunJSSE, class: sun.security.ssl.SSLContextImpl$DefaultSSLContext)

我不确定这里发生了什么，更不用说解决了。我想这与端点是HTTPs服务器有关。我对HTTP的了解很少，所以我不确定是什么原因或如何解决它。

完整的StackTrace(或与OpenESB提供的一样完整):

最佳答案

解决了!感谢@Daniel指出了类似的答案，原来我的OpenESB具有以下启动参数:

"-Djavax.net.ssl.keyStore=%OPENESB_HOME%/keystore.jks" "-Djavax.net.ssl.trustStore=%OPENESB_HOME%/cacerts.jks" -Djavax.net.ssl.keyStorePassword=changeit

删除它们，它可以再次工作:)
