NoSuchAlgorithm when calling Rest WebService

Question

I have this piece of code that directly processes the response out of a REST client:

 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()));

When I run this code (actually it is a jar run my a BPEL within OpenESB) I get the following exception:

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)

I'm not sure what's happening here let alone solve it. I guess this is related to the endpoint being a HTTPs server. I have little experience myself with HTTPs so I'm not sure what's the cause or what to do to fix it.

Full StackTrace (or as full as OpenESB offers):

Could you post the complete Stacktrace? Normally the real culprit is elsewhere and this is just a symptom. — Frank

It should be HttpsURLConnection. Can u typecast u.open connection to HttpsURLConnection and try. — Madhusudana Reddy Sunnapu

@MadhusudanaReddySunnapu I can't do that; this is a jar that's on my web server. It's supposed to work with the endpoint, and I've seen it working on other applications. — MichelReap

Solved it! Thanks to @Daniel for pointing out to a similar answer, turns out my OpenESB had these startup parameters:

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

Removed them and it works again :)
