Weblogic 10.3.6: Registering the Jersey JAX-RS RI Shared Libraries With Your WebLogic Server Instances

Shared Java EE libraries are registered with one or more WebLogic Server instances by deploying them to the target servers and indicating that the deployments are to be shared. Shared Java EE libraries must be targeted to the same WebLogic Server instances you want to deploy applications that reference the libraries.
When a referencing application is deployed, WebLogic Server merges the shared library files with the application. If you try to deploy a referencing application to a server instance that has not registered a required library, deployment of the referencing application fails with following exception

[Extension-Name: jsr311-api, exact-match: false], [Extension-Name: jersey-bundle, exact-match: false].>
java.lang.ClassNotFoundException: com.sun.jersey.spi.container.servlet.ServletContainer

The following steps show how to deploy the Jersey JAX-RS RI Shared Libraries With Your WebLogic Server Instances.

  • Change to the directory C:\WLS10-3-6\Oracle\Middleware\wlserver_10.3\server\bin
  • Execute the cmd file setWLSEnv.cmd

  •  Execute the command
java weblogic.Deployer -verbose -noexit -source C:\WLS10-3-6\Oracle\Middleware\wlserver_10.3\common\deployable-libraries\jersey-bundle-1.1.5.1.war -targets AdminServer -adminurl t3://localhost:7001 -user weblogic -password welcome1 -deploy -library



  • Execute the command.
java weblogic.Deployer -verbose -noexit -source C:\WLS10-3-6\Oracle\Middleware\wlserver_10.3\common\deployable-libraries\jsr311-api-1.1.1.war -targets AdminServer -adminurl t3://localhost:7001 -user weblogic -password welcome1 -deploy -library

Weblogic 12.2.1:Java - JMX to get the Server Name and port

 The following section of code discusses how to get the Server Name and Port for the managed server or a cluster where the API is deployed.

     public static Integer getPort() {
       Integer port=null; 
       try {
            InitialContext ctx = new InitialContext();
            String serverName = System.getProperty("weblogic.Name");

            MBeanServer server =
                (MBeanServer)ctx.lookup("java:comp/env/jmx/runtime");

            ObjectName objName =
                new ObjectName("com.bea:Name=" + serverName + ",Type=Server");
            port = (Integer)server.getAttribute(objName, "ListenPort");
            
            ctx.close();
             
            
        } catch (Exception e) {
            e.printStackTrace();
        }
        return port;
    }

Oracle® Weblogic 10.3.6 Or Higher: Steps to create a Self-Signed Certificate using the SHA-256 Algorithm

Support for SHA-256 with JSSE is supported in WLS 10.3.3 and higher, in conjunction with using the JSSE SSL implementation. It is not supported when using the Certicom SSL implementation, which is deprecated in WLS 10.3.4 and higher.

The following sections describes the steps to create the self signed SHA-256 certificate.

  • Set the WLS domain, by executing the command setDomainEnv.sh or setDomainEnv.sh (Windows)
  • Enter the following pieces of when prompted

$ keytool -genkey -alias selfsignedcert -keyalg RSA -sigalg SHA256withRSA -keypass password1 -keystore identity.jks -storepass password -validity 365

What is your first and last name?
[Unknown]: soad.mindtelligent.com
What is the name of your organizational unit?
[Unknown]: mindtelligent-soa
What is the name of your organization?
[Unknown]: MindTelligent
What is the name of your City or Locality?
[Unknown]: El Dorado Hills
What is the name of your State or Province?
[Unknown]: c
What is the two-letter country code for this unit?
[Unknown]: US
Is CN= soad.mindtelligent.com, OU= mindtelligent-soa, O= MindTelligent, L= El Dorado Hills, ST= El Dorado Hills, C=US correct?
[no]: yes

  • Export the certificate

$ keytool -export -alias Mindteligent-SelfSigned -sigalg SHA256withRSA -file root.cer -keystore identity.jks
Enter keystore password:
Certificate stored in file <root.cer>          


  • Import the root certificate to the trust store:

$keytool -import -alias Mindteligent-SelfSigned  -sigalg SHA256withRSA -trustcacerts -file root.cer -keystore trust.jks
Enter keystore password:
Re-enter new password:

  • Please include the following parameter for startup options.
