    Using certificates within Fuse

    Rogelio Sevilla Novice

      Good day everyone:



      I'm currently developing an application that makes use of ssl certificates to extract information from a https website. I tested the app as a stand alone and everything works as it should. My code look like this:


      URL ur = new URL("my https url");

      System.setProperty("javax.net.ssl.trustStore", "config/myKeyStoreFile")

      URLConnection conn = ur.openConnection();

      OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());

      String outStr=templateProcessorHelper.getRequestTemplate(runtimeValue);

      logger.info("Sending POST Request:\n"+outStr);


      Note: I created the config/myKeyStoreFile file into my Fuse installation folder


      However, when deploying the same application into the ESB, the command conn.getOutputStream() (which is on the fourth line), throws this exception:


      Exception occurred in target VM: java.security.NoSuchAlgorithmException: Error constructing implementation (algorithm: Default, provider: SunJSSE, class: com.sun.net.ssl.internal.ssl.DefaultSSLContextImpl)

      I thought it could be a problem with my certificate, however, i'm using the same jdk version in the stand alone app and on the feature I deployed on fuse but only the latter gives me this problem. I wonder if there's any special process to correctly deploy a certificate into a bundle within fuse or am i mising something else in here??.



      Thanks a lot in advance  :-D

          This was kind of a weird problem, it was pretty hard to find the solution. To be honest, I don't know if it has anything to do with Fuse. Anyway, just in case anyone else is experiencing the same, I solved it by removing this line from my code


          System.setProperty("javax.net.ssl.trustStore", "config/myKeyStoreFile")



          And loading the trustore using my own code, like this:




               SSLSocketFactory sslSocketFactory = null;

                  KeyStore ts = KeyStore.getInstance("JKS");

                  ts.load(new FileInputStream("myKeyStoreFile"),null);

                  TrustManager[] tm2;

                  TrustManagerFactory tmf2 =TrustManagerFactory.getInstance("SunX509",  "SunJSSE");


                  tm2 = tmf2.getTrustManagers();


                  SSLContext sslContext = SSLContext.getInstance("SSL");

                  sslContext.init(null, tm2, null);


                  sslSocketFactory = sslContext.getSocketFactory();

             URL ur = new URL("my https url");       

             HttpsURLConnection conn = (HttpsURLConnection) ur.openConnection();


                  OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());



          Doing this, I was able to visit and send requests to my https site.


          Hope this helps anyone out there :-D
