Recovery needs to recreate the working service and its required data after a machine or process is lost. Which artifacts and state need protection, and how should the restore be checked?
A failure needs to be narrowed down before settings are changed or operations retried. Which evidence best separates application errors from environment and dependency problems?
Hibernate provides setFirstResult() and setMaxResults() to implement database-level pagination. While these methods typically translate to LIMIT or OFFSET clauses based on the SQL dialect, the behavior changes when JOIN FETCH is used to retrieve associated collections. When a query fetches a OneToMany relationship, the resulting Cartesian product can conflic
I am trying to hit a post request to https://login.microsoftonline.com/<My_Tenant_Id>/oauth2/token from my Java Code, but I am getting the error "invalid_grant: AADSTS50126: Error validating credentials due to invalid username or password" .

I have installed Ubuntu 20.4 LTS on WSL. My windows 10 already have the JDK installed. Do I need to install JDK on ubuntu on WSL or can I use the Windows 10 JDK in the Ubuntu? How you do Java programming on WSL? Which is the proper way? I was just wondering if I need to install all the development tools and binaries again on Linux won't it take a lot of spac
Diagnosing intermittent connection pool exhaustion in Java applications requires correlating JVM metrics with specific trace spans. While the Datadog Agent captures database request spans and JVM metrics, there is a potential gap when dealing with transient spikes in connection acquisition time. If a connection pool exhausts rapidly due to a specific outlier
Template Resolution Discrepancy A project utilizes a FileTemplateResolver during local development to enable rapid UI iterations. However, the production environment is configured to use a ClassLoaderTemplateResolver to load templates from the packaged JAR. This transition often introduces discrepancies in how relative paths are resolved between the physical
When building modular UI components in a Spring Boot application using Thymeleaf 3.0+, the choice of fragment inclusion method directly impacts the final DOM structure. The primary goal is to maintain a clean HTML hierarchy while ensuring that essential CSS layout constraints are preserved. Using th:insert preserves the host element, which is useful when the
When implementing pagination in a Java application using Hibernate ORM, the setFirstResult() and setMaxResults() methods are used to limit the result set and define the offset. This ensures the JVM heap is not overwhelmed by large datasets. However, there is a known architectural conflict when these methods are combined with HQL fetch join operations. If a q
