Oracle Java Certification Exam Levels and Categories

Oracle Java Certification exams, which were earlier known as Sun Java Certification exams, are industry respected certifications in Java technology. There are several levels and categories of exams depending on the experience level of the candidate, namely — Junior Associate, Associate, Professional, Expert, and Master. The certifications that focus on Java programming are commonly known as OCAJP and OCPJP. Some people still call them by their old acronyms such as SCJP, SCP, OCJP, and OCP. The Java Expert level certifications focus on specific technologies such as EJBs, JPA, Web Components/Servlet/JSP, and Web Services. They are commonly known as OCE-EJB, OCE-JPA, OCE-WCD, and OCE-JWS.

As of 31st March 2019, Oracle has discontinued several certification exams. Most importantly, the Java EE 6 Certifications for EJB, JPA, Servlet/JSP, Web service exams have been discontinued.

Another important change is that for Java 11 and Java 17, the Oracle Certified Associate level for Java Programmer certification has been removed. Instead of upgrading the OCA Java 8 exam to OCA Java 11 exam, they have completely removed the OCA level for Java 11 and Java 17. There is now only one exam for each of these two Java versions. The 1Z0-819 exam for OCP Java 11 and the 1Z0-829 exam for OCP Java 17.

Furthermore, there are no «upgrade» exams anymore. So, for example, if you are already OCP Java 8 or Java 11 certified, there is no special upgrade exam to acquire OCP Java 17 certification. You need to take the regular 1Z0-829 exam to acquire it.

All Java Certification exams are listed below with their exam codes —

Skills/Certification	Exam Code	Experience Level	Status	Java Version
Java Foundations Certified Junior Associate (JFCJA)	1Z0-811	Newbie	Current	Java 8
Oracle Certified Professional, Java SE 17 Programmer (OCPJP/SCJP)	1Z0-829	2 years+	Curent	Java 17
Oracle Certified Professional, Java SE 11 Programmer (OCPJP/SCJP)	1Z0-819	2 years+	Curent	Java 11
Oracle Certified Professional, Java SE 6 7 8 to 11 Programmer UPGRADE (OCPJP/SCJP)	1Z0-817	2 years+	DISCONTINUED	Java 11
Oracle Certified Associate, Java SE 8 Programmer (OCAJP/SCJA)	1Z0-808	0-2 Years	Outdated but still Exists	Java 8
Oracle Certified Professional, Java SE 8 Programmer (OCPJP/SCJP)	1Z0-809	2 Years+	Outdated but still Exists	Java 8
Oracle Certified Professional, Java EE 7 Application Developer	1Z0-900	4 Years+	Still Exists	Java EE 7

Note that the experience level is not required by Oracle but is just a guideline.

  SunCertPathBuilderException: Unable to Find Valid Certification Path to Requested Target Error in Java

  

  1. What Is the sun.security.provider.certpath.SunCertPathBuilderException in Java
  2. Causes of sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
  3. Solution of sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

  Today’s post will discuss potential reasons for unable to find valid certification path to requested target and its solution in Java.

  But, before we continue, you must clearly understand SSL encryption and Certificates since a clear understanding of SSL Certificates is required.

  SSL encryption and Certificates: an HTTPS connection cannot function properly without an SSL certificate. Through the use of a set of public and private keys, it substantiates the claimed identity of the service or website.

  The private key encrypts or signs everything that is delivered by the domain, and the client apps validate the identification by utilizing the public keys.

  What Is the sun.security.provider.certpath.SunCertPathBuilderException in Java

  The sun.security.provider.certpath.SunCertPathBuilderException is a class for handling exceptions in Java that checks the server’s SSL certificates that the Java program is attempting to connect to. This class was named after the provider that created the certificates.

  The following is the error message shown to the developer when they encounter this issue.

  Caused by: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target 

  It can be thrown during any action involving visiting an encrypted service using SSL.

  SSL-protected APIs and websites are checked for trustworthiness by the Java framework before they can be accessed. This is accomplished by examining its internal trusted list to see whether the root certificate authority signed is in there.

  Java throws this error if it can’t discover any reference to the service. Using a self-signed certificate to access a service signed by someone else’s digital signature will always fail.

  Causes of sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

  The only way Java will be able to connect to another program via SSL is if it can trust HTTPS, etc. There is a truststore usually $JAVA HOME/lib/security/cacerts in the Java world where you store your trust certificates.

  This exception is triggered by a self-signed certificate or a certificate chain that does not exist in the Java trust store. Java refuses to connect to the application because it does not trust the certificate.
