The full name of HBM is Hibernate Mapping. It is an XML file in which we define the mapping between POJO class to the database table and POJO class variables to table columns. The resource file hibernate.cfg.xml, which supports the representation of the Hibernate configuration information. The connection.driver_class, connection.URL, connection. username, and connection. password property element that characterizes the JDBC connection information. The connection.pool_size is used to configure Hibernate’s built-in connection pool how many connections to the pool. The Hibernate XML mapping file includes the mapping correlation between the Java class and the database table. It is mostly named “xx.hbm.xml” and represents in the Hibernate configuration file “hibernate.cfg.xml.”

For example, the mapping file (hbm.xml) is mentioned in the “mapping” tag.

  <property name="hibernate.bytecode.use_reflection_optimizer">false</property>

  <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>

  <property name="hibernate.connection.password">password</property>

  <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/demo</property>

  <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>

Add Hibernates mapping file (hbm.xml) programmatically:

Hibernate provides a method for the developer to add mapping files technically.

Let’s modify the default Hibernate SessionFactory class bypassing your “hbm.xml” file path as an argument into the addResource() method:

Configuration().addResource(“com/demo/commonStock.hbm.xml”).buildSessionFactor();

Example of HibernateUtil.java, load the Hibernate XML mapping file demo.hbm.xml” programmatically:

       private static final SessionFactory sessionFactory = buildSessionFactory();

       private static SessionFactory buildSessionFactory() {

                     SessionFactory sessionFactory = new Configuration()

                                  .configure("/com/demo/persistence/hibernate.cfg.xml")

                                  .addResource("com/demo/common/Stock.hbm.xml")

                                  .buildSessionFactory();

                     return sessionFactory;

                     System.err.println("Initial SessionFactory creation failed." + e);

                     throw new ExceptionInInitializerError(e);

Two property elements declare the remaining two properties of the Event class: i.e., date and title. 

The date belongings mapping includes the column attribute, however, the title does not have. While a column attribute is absent, hibernate makes use of the property name as the column name. This is suitable for the identity, however, because the date is a reserved keyword in most of the databases.

public static SessionFactory getSessionFactory() {

              // Close caches and connection pools

              getSessionFactory().close();

There is two way of mapping in hibernate – The first one which is by using the hibernate annotation and the second one which is by using the hbm.xml.

When we use hbm.xml, to just modify the default hibernate SessionFactory class in hibernate-cfg.xml bypassing your “hbm.xml” file path as an argument to resource method.

Example: Here, we are taking an example of the employee table.

Employee.hbm.xml file is your hbm.xml file in which table column and their types are mapped.

hibernate-cfg.xml is the configuration file of hibernating where you map hbm.xml

<property name="connection.driver_class">com.mysql.jdbc.Driver</property>

<property name="connection.url">jdbc:mysql://localhost:3306/hibernate</property>

<property name="dialect">org.hibernate.dialect.MySQLDialect</property>

<property name="current_sesion_context_class">thread</property>

<property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>

In the world of modern software development, seamless integration and automation are critical. Azure DevOps, a powerful cloud-based platform, offers a comprehensive set of tools for managing the entire software development lifecycle. One such essential feature is the ability to define environment variables, which enable the configuration of various settings within your pipelines. In this blog, we will walk you through a step-by-step guide on how to define environment variables in Azure DevOps, empowering you to enhance your CI/CD workflows and streamline your development processes.

Step 1: Accessing Your Azure DevOps Project

To get started, access your Azure DevOps account and navigate to the specific project where you want to define environment variables. Ensure that you have the necessary permissions to modify the project settings.

Once you are in your project, choose the pipeline to which you want to add the environment variables. If you don't have an existing pipeline, you can create a new one by configuring your build and release pipeline settings according to your requirements.

In the selected pipeline, click on the "Edit" button to access the pipeline settings. You will find this option in the top-right corner of the pipeline view.

In the pipeline settings, navigate to the "Variables" tab. Here, you can either define variables directly within the pipeline or create a new variable group to manage variables more efficiently across multiple pipelines. For this guide, we will create a new variable group.

Click on the "Variable groups" option and then select "Add" to create a new variable group. Provide a meaningful name and description for the group to easily identify its purpose.

With the new variable group created, you can now define your environment variables. Click on "Add variable" and enter the variable name and its corresponding value. Optionally, you can mark a variable as a secret if it contains sensitive information, ensuring it is encrypted and securely stored.

Azure DevOps allows you to specify the scope of your variable group. You can choose between different options, such as the entire organization, specific projects, or even individual pipelines. Select the appropriate scope that aligns with your intended usage.

After defining the environment variables, you need to link the variable group to the desired pipeline. In your pipeline settings, locate the "Variable groups" section and click on "Link variable group." Choose the relevant variable group from the list and save your changes.

Step 9: Using Environment Variables in Pipelines

Now that your variable group is linked to the pipeline, you can access the defined environment variables within your YAML or classic pipelines. Use the syntax $(variableName) to reference the variables wherever needed in your pipeline configuration.

Once you have added and linked the variable group, save the pipeline settings. Now, trigger a new build or release for your pipeline to see the environment variables in action. The defined variables will be available during the pipeline execution, ensuring seamless configuration and flexibility in your workflows.

Defining environment variables in Azure DevOps provides a powerful mechanism for configuring and customizing your CI/CD pipelines. By centralizing and managing variables through variable groups, you can streamline your development processes, enhance security by handling sensitive data, and promote reusability across multiple pipelines. With this step-by-step guide, you are now equipped to leverage environment variables effectively in Azure DevOps, paving the way for more efficient and automated software delivery.

Learn how to define environment variables in Azure DevOps, streamlining CI/CD workflows and promoting secure and flexible configuration in just 10 steps.

Azure Cloud has gained significant traction as a reliable platform for hosting applications and services. While its offerings are robust, developers sometimes encounter perplexing error messages that demand careful investigation. One such error message is "'The matching wildcard is strict, but no declaration can be found for the element 'camelContext'". In this blog post, we'll delve into the meaning behind this error and provide insights into its potential causes and solutions.

The error message "'The matching wildcard is strict, but no declaration can be found for the element 'camelContext'" might appear baffling at first glance. To decipher its meaning, we need to break down the key elements:

Matching Wildcard: Refers to a wildcard character (*) used in configuration or settings files to match multiple elements.

Strict Declaration: Implies that the structure and elements in the configuration need to adhere to a specific schema or format.

camelContext: Likely refers to Apache Camel, an open-source integration framework that facilitates routing, mediation, and transformation of data.

Incorrect Configuration: The error could result from an incorrect configuration in your application, especially in the XML files where you define the structure of your Camel context. If the configuration does not match the expected format, the error can occur.

Missing Dependencies: If you're using Apache Camel in your Azure Cloud application, ensure that you have the necessary dependencies properly defined. Missing or mismatched dependencies can lead to issues with the Camel context.

Syntax Errors: Even a minor syntax error in your configuration files can trigger this error message. A missing closing tag, an extra character, or a misconfigured element could cause the error.

Version Incompatibility: If you're using a specific version of Apache Camel or related libraries, it's crucial to ensure that the versions are compatible with each other and with the Azure environment.

Carefully review your configuration files, particularly those related to Apache Camel. Ensure that the structure, elements, and syntax are accurate. Pay attention to closing tags, attributes, and the overall hierarchy of the configuration.

Double-check your project's dependencies. Ensure that you've included the necessary Apache Camel libraries and that they are of compatible versions. Use tools like Maven or Gradle to manage your dependencies effectively.

Thoroughly analyze your configuration files for any syntax errors. Even a small mistake can lead to significant issues. Consider using XML validation tools or integrated development environment (IDE) features to identify and rectify syntax errors.

Make sure that the version of Apache Camel you're using aligns with your project's requirements and Azure Cloud's environment. If needed, update or downgrade the Apache Camel version to achieve compatibility.

Azure Cloud and Apache Camel have extensive documentation. Review the documentation related to both platforms to ensure you're following best practices and guidelines. Often, solutions to common errors are documented, helping you resolve issues faster.

If you're unable to identify the root cause and solution on your own, consider reaching out to online communities and forums related to Azure Cloud and Apache Camel. Experienced developers might have encountered similar issues and can provide insights.

The error message "'The matching wildcard is strict, but no declaration can be found for the element 'camelContext'" in Azure Cloud is a result of misconfigured or incompatible settings, likely related to Apache Camel configuration. By meticulously examining your configuration files, validating dependencies, and ensuring proper syntax, you can troubleshoot and resolve this error effectively. Remember to consult official documentation and seek help from the developer community when needed. With patience and attention to detail, you can navigate and conquer this error, ensuring the smooth functioning of your application on the Azure Cloud platform.

In Nginx, what's the difference between variables $host and $http_host.

What's the difference of $host and $http_host in Nginx

I would like to run a Kafka cluster with 2 listeners. One SSL and one PLAINTEXT listener. The SSL listener should be secured by authentication/authorization via SSL and ACL. Only known users should be allowed to access it.

On the PLAINTEXT port any user or anonymous user should have full access.

however, anonymous users will no longer be able to access the PLAINTEXT port. Is there any way to configure the system as described above?

Can I Use SSL and ACL authentication/authorization only for SSL listener (not for PLAINTEXT) in Kafka?

I've been given a purchaser seeking to get the right of entry to consider one of my websites, and they preserve getting this error > ssl_error_rx_record_too_long

They are getting this mistake on all browsers, all structures. I cannot reproduce the hassle in any respect.

My server and myself are placed within the u.S.A., the customer is positioned in India.

I googled the problem, and the principle supply seems to be that the SSL port is speaking in HTTP. I checked my server, and this isn't taking place. I tried the answer mentioned right here, however, the consumer has said it did not restore the problem.
