I'm trying to use the class "MyApplication". but I got messages such as my title. first of all, I added as (android:name = ".MyApplication"). and also added ( android:allowBackup="true"). but You can see my second screenshot. The Notice said MyApplication is an unresolved class... What should I do for resolving it?

I am trying to write a code to convert csv to bean using opencsv and xml to bean using jaxb.
I tried using lombok.
The getters are not getting resolved even after lombok has generated them.
Exception with JAXB:

Can someone help me?

JSF component binding is never used in the application. Looking at the Primefaces source I can see that the model SortMeta (does not implements Serializable) is only used in the DataTable component.
The view state saving method has to be server side.
How to solve or avoid this exception?
EDIT:
Problem was caused by the "new" datatable attribute multiViewState.
https://forum.primefaces.org/viewtopic.php?f=3&t=54138&p=164132
Class SortMeta is now Serializable:

I'm using the last version of the generator-jhipster.
I have made a microservice-application, build it, it's a success.
Now I'm creating an entity and when I run it, I get this stack trace:

I didn't modify anything, did I do something wrong ?
I had the same issue and my solution may or may not apply to your case. In my case, a previous version of JHipster had generated the hibernate_sequence only for some database types, not including h2 used for tests.
Check your 00000000000000_initial_schema.xml liquibase file, it should contain the instructions for creating the hibernate_sequence sequence, for instance:
<changeSet id="00000000000000" author="jhipster" dbms="postgresql,oracle">
<createSequence sequenceName="hibernate_sequence" startValue="1000" incrementBy="1"/>
</changeSet>
This did not include h2, so the sequence was not generated during testing and thus Hibernate complained.
I removed the dbms="postgresql,oracle" part and then it worked.
your application is failing to load ApplicationContext. Check your folder where it is configured
#ContextConfiguration (locations = "classpath*:/spring/applicationContext*.xml")
this will load all of your application context xml file.
According to stack trace,
Your test class with SpringJUnit4ClassRunner needs a spring context and your spring configuration for this test class needs a bean that's name entityManagerFactory
You must add this bean to your test config(HibernateJpaAutoConfiguration)
For ex:
in Java Config:
#Bean
public EntityManagerFactory entityManagerFactory(){
return new EntityManagerFactory(...){
....
}
}
or autowired:
#Autowire
private EntityManagerFactory entityManagerFactory;
I followed the instructions to install the XSP Starter kit from openntf. Everything mentioned in the video I was able to do but I am not able to activate it.
When I activate the plugin in my application and try to open it I get an Error 500. Anybody any idea?
The server console tells me:

There is a component that was available in the starter kit for org.openntf.xsp.starter.renderkit.AbstractHtmlTagRenderer. It's hitting an error trying to create that component. It's not a component designed to be used in a particular way, it's really there to show what needs to be created for a component - org.openntf.xsp.starter.AbstractHtmlTag is the component, html.xsp-config in META-INF defines the properties available to Domino Designer, html-faces-config adds the component to the server and defines which Java class to use for the component and which one for the renderer (to display the HTML). org.openntf.xsp.starter.renderkit.AbstractHtmlTagRenderer handles printing content to the browser.
I've not used the starter kit as is, but I did use it as a basis for my session at ICON UK http://www.slideshare.net/paulswithers1/from-xpages-hero-to-osgi-guru-taking-the-scary-out-of-building-extension-libraries-icon-uk-2014
