When I call the method llaveCom.getName() I always get a null, I don't know why

Code of component"

Hey to all in the forum

I use JSF Mojarra implementation, version JSF 2.2

I need desperately a help on this.

1. I have a snippet of my page.
2. I have a custom component "example_result.xhtml" used in the page.
3. I have my BackingBean.java Be aware please that this code is not the real code I made. If you run it, it will be very ugly maybe because I deleted all the css classes and I kept only the hot stuff I need to show you my problem.

Everything is inside 1 form.

The 5 "h:selectManyCheckbox" (in my code I have 8 or 9)

In the form I have 5 "h:selectManyCheckbox" which are using values in the "value" attribute for different cases (javaFrameworks2Values, javaFrameworks3Values,...), and the "f:selectItems" use arrays of "SelectItem" (javaFrameworksSelectItems2, javaFrameworksSelectItems3...) created for these different cases, just to make some examples for me to understand how all the selectOne and selectMany components work. The ideas for this, about different cases were taken from these links: "https://stackoverflow.com/tags/selectonemenu/info" and "https://mkyong.com/jsf2/jsf-2-checkboxes-example".

After I have 2 commandButtons

1 for submit, and 1 for reset the values.

Display the values

After I display the results of the values of the "h:selectManyCheckbox" via the "example_result.xhtml".

You can see the 4th "h:selectManyCheckbox" that is the only one different, because it has the attribute "required" with the attribute "requiredMessage". With it there is a "h:message" to display the validation error.

In the BackingBean (which is Spring Bean, but it works perfectly good - sorry I don't want ejbs 3.x), I have initialized:

1. The values of the SelectItems and
2. The values of the "value" attribute, where the values of the "h:selectManyCheckbox" will be stored to be displayed later. [The code is completely castrated, to make it readable snippet].

When the page is rendered, I select checkBoxes (e.g. the 2 last, because the 2 first are initials) from all the "h:selectManyCheckbox". When I say that select from all, I mean it. And from the 4th with the "required" attribute. I try in the buttons (see in the code) the "Effort 1", or "Effort 2", or "Effort 3" (in the "f:ajax" in the buttons) and the result outputs in the last part are displayed and updated like a candy. Without any problem. To achive this with the composite component I googled and tried a lot. But I made it.

Then it comes the time to try the 4th to see the validation error of the "required" attribute.

I select again from all as before, but not from all. NOT from the 4th "h:selectManyCheckbox" this time. I select nothing from the 4th "h:selectManyCheckbox" to ckeck the validator error message ("requiredMessage"). The result is: It displays the message of error (GOOD until now), BUT this time it does not update anything from the others "h:selectManyCheckbox" to the output results at the end, and it does not reset the values as well as it was doing before (when I selected from all and from the 4th as well).

I understand that it says: as long as in the form the 4th failed with validation error, all the other "h:selectManyCheckbox" will not update the output results (something like wanting to fail all the others too).

But what really happes here?

1. It does not give the values to the "h:selectManyCheckbox", to be updated to the output?
2. It gives the vales to the "h:selectManyCheckbox" normally, BUT it just not updates the output?

The other efforts in the "f:ajax" in the buttons, are just efforts maybe to solve the problem but in these cases they don't even display the error message in the 4th case and of cource they don't update the other output results as well (again). But no message error as well.

I don't know if the problem is clear to you. I can explain in the discussion better so I can clarify the situation better. [To be honnet it took me 1 and half hour to write all this thing]

Thanks a lot in advance

========== Snippet from my page ==========

This probably ins't typical setup, but due to higher decisions we endup having multiple kafka clusters within one app, multiple topics per each, and each might have different serializing strategy. Json/avro. And avro might be with confluent schema registry or using single object encoding.

Well I got it working somehow, by building my own abstractions and registry which analyzes the configuration and creates most of stuff manually, but I feel I needed to repeat stuff like topic names, schema registry url on several places multiple times just to create all needed beans. Ugly as hell.

I'd like to ask, if there is some better way and support for this I just might have overlooked.

I need to create N representations of kafka clusters, configuring it once. Configure topics respective to given kafka cluster, configure confluent schema registry for topics where applicable etc, so that I can create instance of Avro schema file, send it to KafkaTemplate and it will work.

I'd like to implement UPDATE (method PUT) operation for REST api. From front-end application my controller method expects map of values, for example:

I'm currently working on a project running a jboss backend server (server-ear:ear exploded artefact) and a java gui (java 11) as frontend.

The backend contains a java service bean which accesses a database server and throws a custom exception (extends exceptions), if the variable is not found. The GUI catches the custom exceptions with a try and catch block.

The code is build and run inside of Intellij + Maven.

If i try to execute the code following arrow pops up at runtime:

I am using spring-boot 2.2.7.RELEASE

In the controller I want to get some values from external config file. But the application does not start even though the properties are available in the external config.

could you suggest how to load only specific properties from external config.

NOTE: I also tried spring.config.additional-location, and it is not working

Thanks

Controller

I need to push messages to external rabbitmq. My java configuration successfully declares queue to push, but every time I try to push, I have next exception:

Using Spring Batch, I have to write in two different table, but using the same ItemReader.

I can't figure out how to use one ItemReader and a CompositeItemWriter.

Here's the JobConfiguration :

I am using WSO2 APIM 2.1.0 and IS 5.3.0

I'm currently trying to create an API that registers a certain user by calling the admin service UserInformationRecoveryService which gives out a custom JSON response if the creation is successful and another response if it is unsuccessful, in which case the user already exists.

So far I have written the in sequence and the out sequence as follows but I am having trouble getting the expected output.(The success response is always seen even when the user already exists. That is, the else block is getting executed in the out sequence.)

In Sequence
