i write a java program which used the apache httpclient, the program run well on my windows, however error occured on my linux sever. The following is the exception.
The key code is :
CloseableHttpClient httpclient = HttpClients.createDefault();
With error
Exception in thread "main" org.apache.http.ssl.SSLInitializationException: TLS SSLContext not available
at org.apache.http.ssl.SSLContexts.createDefault(SSLContexts.java:58)
at org.apache.http.impl.client.HttpClientBuilder.build(HttpClientBuilder.java:966)
at org.apache.http.impl.client.HttpClients.createDefault(HttpClients.java:58)

at org.apache.http.ssl.SSLContexts.createDefault(SSLContexts.java:54)
... 3 more
jar file httpclient 4.5.2
jdk version 1.8.0_101
This problem annoyed me for quite a while....
I work in eclipse on my windows( which the program runs well ) to attach the httpcore src and find the error code
public static SSLContext createDefault() throws SSLInitializationException {
try {
final SSLContext sslcontext = SSLContext.getInstance(SSLContextBuilder.TLS);
sslcontext.init(null, null, null);
return sslcontext;
} catch (final NoSuchAlgorithmException ex) {
throw new SSLInitializationException(ex.getMessage(), ex);
} catch (final KeyManagementException ex) {
throw new SSLInitializationException(ex.getMessage(), ex);
}
}
so I think the SSLContext.getInstance run error on my remote linux server, but I don't know the reason. it's weird however ok on windows.
