The 'beans' of JavaBeans are classes that encapsulate one or more objects into a single standardized object (the bean). This standardization allows the beans to be handled in a more generic fashion, allowing easier code reuse and introspection. This in turn allows the beans to be treated as software components, and to be manipulated visually by editors and IDEs without needing any initial configuration, or to know any internal implementation details.
The first two roles, Java EE product provider and tool provider, involve purchasingand installing the Java EE product and tools. After software is purchased andinstalled, Java EE components can be developed by application component providers, assembled byapplication assemblers, and deployed by application deployers. In a large organization, each ofthese roles might be executed by different individuals or teams. This division oflabor works because each of the earlier roles outputs a portable file thatis the input for a subsequent role. For example, in the application componentdevelopment phase, an enterprise bean software developer delivers EJB JAR files. In the applicationassembly role, another developer may combine these EJB JAR files into a JavaEE application and save it in an EAR file. In the application deploymentrole, a system administrator at the customer site uses the EAR file toinstall the Java EE application into a Java EE server.

GitHub is now the new home for Beanshell's source code. We are currently moving much of the content and undergoing heavy development there. Please be patient while we cleanup old content in this site.
JSR-274 the BeanShell Scripting Language, has passed the voting process with flying colors. This means that we will proceed with forming the expert group to write a language specification and work towards getting BeanShell included in the J2SE at some point in the future. Some comments on the initiating the JSR can be found in Pat Niemeyer's blog on java.net.
Join us for a BeanShell BOF session at JavaOne, 2005. The talk is tentatively titled "The Future of BeanShell and Java Compatible Scripting". We'll also be cooperating with the JSR-223 session on the new javax.script API which will be bundled with an upcoming J2SE release.
With version 2.0 BeanShell becomes a fully Java compatible scripting language. BeanShell is now capable of interpreting ordinary Java source and loading .java source files from the class path. BeanShell scripted classes are fully typed and appear to outside Java code and via reflective inspection as ordinary classes. However their implementation is fully dynamic and they may include arbitrary BeanShell scripts in their bodies, methods, and constructors. Users may now freely mix loose, unstructured BeanShell scripts, method closures, and full scripted classes. Please see the announcement for details and known bugs in the initial release.
Written in the Java programming language, an enterprise bean is a server-side componentthat encapsulates the business logic of an application. The business logic is thecode that fulfills the purpose of the application. In an inventory control application,for example, the enterprise beans might implement the business logic in methods calledcheckInventoryLevel and orderProduct. By invoking these methods, clients can access the inventory servicesprovided by the application.
For several reasons, enterprise beans simplify the development of large, distributed applications. First,because the EJB container provides system-level services to enterprise beans, the bean developercan concentrate on solving business problems. The EJB container, rather than the beandeveloper, is responsible for system-level services such as transaction management and security authorization.
Third, because enterprise beans are portable components, the application assembler can build newapplications from existing beans. These applications can run on any compliant Java EEserver provided that they use the standard APIs.
Can someone direct me to a maven example project where its deployed into elastic bean stalk behind an nginx (which is the default) and modifies the client_max_body_size similarly to what i want or does any other modification to nginx.
I do something similar but I use Apache instead nginx, but I do something very similar to overwrite the existing apache config file 00_application.conf ; I put the replacement file in the .platform/httpd/conf.d/elasticbeanstalk direct which starts at the root of the artifact ( .war or .zip file ) . It took a while to get it exactly right, I ended up configuring the beanstalk instances so that I could get to them using the SSM agent so I was able to ssh onto them and troubleshoot and check the results.
So this can be one workaround for the people trying to deploy their app using a jar file, the optimal solution would be to package the app in such a way automatically but this has to do more with maven and the pom file rather than elastic beanstalk, still it would be good if aws could provided an example project.
Everything you wrote i had already went through, doesn't really help someone to solve the issue but thank you for trying, also an answer is already accepted on this thread. for anyone looking for a helpful and detailed answer have a look at this -> _LAuP8cWA/java-maven-deployed-in-elastic-bean-stalk-how-to-install-3rd-party-package-wkhtmltopdf

Bean discovery in CDI is a complex process which involves legacy deployment structures and accessibility requirements of the underlying module architecture.However, Quarkus is using a simplified bean discovery.There is only single bean archive with the bean discovery mode annotated and no visibility boundaries.
In CDI, a normal scoped bean must always declare a no-args constructor (this constructor is normally generated by the compiler unless you declare any other constructor).However, this requirement complicates constructor injection - you need to provide a dummy no-args constructor to make things work in CDI.
The optimization can be disabled by setting quarkus.arc.remove-unused-beans to none or false.Quarkus also provides a middle ground where application beans are never removed whether or not they are unused, while the optimization proceeds normally for non application classes.To use this mode, set quarkus.arc.remove-unused-beans to fwk or framework.
Users can instruct the container to not remove any of their specific beans (even if they satisfy all the rules specified above) by annotating them with @io.quarkus.arc.Unremovable.This annotation can be declared on a class, a producer method or field.
Since this is not always possible, there is an option to achieve the same via application.properties.The quarkus.arc.unremovable-types property accepts a list of string values that are used to match beans based on their name or package.
Default beans can optionally declare @jakarta.annotation.Priority.If there is no priority defined, @Priority(0) is assumed.Priority value is used for bean ordering and during typesafe resolution to disambiguate multiple matching default beans.
Quarkus adds a capability that CDI currently does not support which is to conditionally enable a bean when a Quarkus build time profile is enabled,via the @io.quarkus.arc.profile.IfBuildProfile and @io.quarkus.arc.profile.UnlessBuildProfile annotations.When used in conjunction with @io.quarkus.arc.DefaultBean, these annotations allow for the creation of different bean configurations for different build profiles.
Imagine for instance that an application contains a bean named Tracer, which needs to do nothing when in tests or in dev mode, but works in its normal capacity for the production artifact.An elegant way to create such beans is the following:
Quarkus adds a capability that CDI currently does not support which is to conditionally enable a bean when a Quarkus build time property has/has not a specific value,via the @io.quarkus.arc.properties.IfBuildProperty and @io.quarkus.arc.properties.UnlessBuildProperty annotations.When used in conjunction with @io.quarkus.arc.DefaultBean, this annotation allow for the creation of different bean configurations for different build properties.
In CDI, an alternative bean may be selected either globally for an application by means of @Priority, or for a bean archive using a beans.xml descriptor.Quarkus has a simplified bean discovery and the content of beans.xml is ignored.
However, it is also possible to select alternatives for an application using the unified configuration.The quarkus.arc.selected-alternatives property accepts a list of string values that are used to match alternative beans.If any value matches then the priority of Integer#MAX_VALUE is used for the relevant bean.The priority declared via @Priority or inherited from a stereotype is overridden.
Only method-level bindings are considered for backward compatibility reasons (otherwise static methods of bean classes that declare class-level bindings would be suddenly intercepted)
There is no standard concurrency control mechanism for CDI beans.Nevertheless, a bean instance can be shared and accessed concurrently from multiple threads.In that case it should be thread-safe.You can use standard Java constructs (volatile, synchronized, ReadWriteLock, etc.) or let the container control the concurrent access.Quarkus provides @io.quarkus.arc.Lock and a built-in interceptor for this interceptor binding.Each interceptor instance associated with a contextual instance of an intercepted bean holds a separate ReadWriteLock with non-fair ordering policy. 0852c4b9a8
