I recently changed my domain objects from LocalDate to ZonedDateTime. I also created a brand new play JHipster application and one play entity choosing ZonedDateTime for two class members. The test application (new) works while my existing application does not, even after going through all the code twice. I loaded CSV data using Liquibase and my listing code shows the dates properly. Here's what the data looks like in my Maven output, e.g. entrydate='2017-02-23T19:53:18-05:00[America/New_York]', transaction='Initial Balance',
When I choose to update the date-time value with the "datetime-picker" in the dialog.html, a string date time is shown in the text box but when I push "Save" I get an "Internal Server Error" and the Maven output shows:
.HttpMessageNotReadableException: Could not read document: Text '2017-02- 26T00:53:18.000Z' could not be parsed at index 23 (through reference chain: org.ciwise.blackhole.domain.GenLedger["entrydate"]); nested exception is com.fasterxml.jackson.databind.JsonMappingException: Text '2017-02-26T00:53:18.000Z' could not be parsed at index 23 (through reference chain: org.ciwise.blackhole.domain.GenLedger["entrydate"])]
Does anyone have an idea why the picker would produce String text in the text box that isn't acceptable when the HTTP PUT occurs (edit)?
My application does use Service classes but they handle the same Java domain objects as the JPA Repository classes do.
One more thing, the schema for the API shows e.g. "entrydate": "2017-02-23T21:44:04.859Z", but the actual JSON return is "entrydate": "2017-02-23T19:53:18.000-0500",
I'm hoping someone else has encountered this before.
Thanks

The answer here was to re-introduce application.yml. Inside this file it defines some Spring profiles but of most importance, it provides an option for Jackson serialization into JSON e.g.
jackson:
serialization.write_dates_as_timestamps: false
This resolved my issue.

I'm trying to use resteasy-rxjava2 to provide an XML document using jaxb, within a vertx application (using a non-vertx legacy library we have). But I get:
Could not find MessageBodyWriter for response object of type:
org.jboss.resteasy.rxjava2.propagation.ContextPropagatorOnSingleAssemblyAction$ContextPropagatorSingle of media type:
application/xml;charset=UTF-8
From what I can tell, this comes down to the difference between a MessageBodyWriter and the AsyncResponseProvider that is in the resteasy-rxjava2 dependency for a Single (SingleProvider).
I have the following resteasy service definition
#GET
#Path(FdsnwsPaths.QUERY)
#Produces(MediaType.APPLICATION_XML)
#Stream
// CHECKSTYLE:OFF too many parameters
public Response getQuery(...)
How do I get resteasy to properly serve the data asynchrously, using the SingleProvider or otherwise.
The #Get method must return the Single explicitly or it doesn't work. (Can't use Response or Object). In my case, the Single contains the jaxb xml root element.
#GET
#Path(FdsnwsPaths.QUERY)
#Produces(MediaType.APPLICATION_XML)
#Stream
public Single<FDSNStationXML> getQuery(...)
Then, to make things more complicated, in order to handle specific exception types and map them to specific response status codes, I have to create a custom ExceptionMapper which creates the Response object I used to be able to create directly in the method. (in resteasy-vertx, I found no documentation on how to do this, but in my case, I am creating my own VertxRestEasyDeployment object so I can register the class of the ExceptionMapper(s) like this:
VertxResteasyDeployment deployment = new VertxResteasyDeployment();
deployment.getActualProviderClasses().addAll(providerClasses);
For reference, this is all being done with:
RestEasy 5.0.3.Final (including resteasy-rxjava2)
RxJava 2.2.20
Vertx 3.9.5
I've been plagued for months with an error in ODM.
It doesn't prevent my services from working, it only prevents ODM from automatically generating the JSON input payload when I test a service through the Rule Execution Server (the Retrieve HTDS Description File).
I attached a screenshot of the error.
What is puzzling is that:
if I move my variable from Input to Output, then the JSON gets generated in the Server Response section
if I manually enter my own JSON, the service executes correctly and I get back a decision
Does anyone have any idea what could possibly be wrong here?
Very likely your variable is not being deserialized properly. This would explain both the error you are getting and why you get it only as an input variable.
We get a similar error using a java.tim.ZonedDateTime with ODM 8.9.1, which does not support the java.time package. We just ignore the error -- and are hoping we can avoid it when we move to ODM 8.10.2.
hard to help as some of the context is missing. However the symptoms you describe tells there is a serialization issue one of the class of the HTDS interface.
It could be :
a getter/setter missing
a dependency missing in the XOM (classloader)
or a #jsonIgnore missing on a non getter/setter method whose name starts by get or set.

My task is to translate all the messages of an application into another language, different than English. The tricky part is with the messages generated by the JSF framework itself. I came across various articles showing how to customize some particular conversion or validation error message, but i am interested in customizing every possible error message that the application might generate (including, for example, authentication and navigation error messages).
Is there a file that contains all the possible error messages?
So far, i came across a file named Messages.properties, located in the jsf-api jar , which contains Validation, Converter and Component error messages. But that is not enough, there is plenty other errors apart from these.
This jar is actually named jboss-jsf-api_2.1_spec-2.1.28.Final-redhat-1.jar and is located under jboss-eap\modules\system\layers\base\javax\faces\api\main folder.
Inside this jar, the Messages.properties file is located under the javax\faces package.
I currently use Red Hat JBoss Enterprise Application Platform - Version 6.4.0.GA, JSF Implementation-Version: 2.1.28.Final-redhat-1
The problem can be split into two parts:
How do i override a framework error message?
What is the list of all possible error messages that can be generated by the JSF framework?
Part 1: OVERRIDING FRAMEWORK'S ERROR MESSAGES
In my project, under WebContent\WEB-INF, there is faces-config.xml, which contains <message-bundle>resources</message-bundle>. 'resources' points to src\resources.properties. In this .properties file, i just have to add the corresponding entries, like
javax.faces.converter.DateTimeConverter.DATE={2}: ''{0}'' non poteva essere inteso come una data.
Should such error be generated by the application, the translated message will be displayed.
However, as i understand from Cannot override validation error message, the use of a resources.properties file under src is maven specific. Different packaging technologies may require different solutions.
Part 2: LIST OF ALL ERROR MESSAGES
Taking a look at the files contained in javax.faces.jar http://www.java2s.com/Code/Jar/j/Downloadjavaxfacesjar.htm , i see the following packages:
javax.faces.application
javax.faces.bean
javax.faces.component
javax.faces.context
javax.faces.convert
javax.faces.el
javax.faces.event
javax.faces.lifecycle
javax.faces.model
javax.faces.render
javax.faces.validator
javax.faces.view
javax.faces.webapp
For every class in each of these packages, i have to add entries in the resources.properties for every error that this class might raise.
But what are the errors that a class might raise? And what should the entry in the resource.properties look like?
I let myself guided by the entries that I've found in the Messages.properties file inside the jboss-jsf-api_2.1_spec-2.1.28.Final-redhat-1.jar (which I've mentioned in the question). It has the following entries, among many others:
# ==============================================================================
# Component Errors
# ==============================================================================
javax.faces.component.UIInput.CONVERSION={0}: Conversion error occurred.
javax.faces.component.UIInput.REQUIRED={0}: Validation Error: Value is required.
javax.faces.component.UIInput.UPDATE={0}: An error occurred when processing your submitted information.
In my IDE (eclipse), i click on an import statement import javax.faces.component.UIInput; to navigate to UIInput.class . In the Class File Editor , i have the following lines :
// Field descriptor #193 Ljava/lang/String;
public static final java.lang.String CONVERSION_MESSAGE_ID = "javax.faces.component.UIInput.CONVERSION";
// Field descriptor #193 Ljava/lang/String;
public static final java.lang.String REQUIRED_MESSAGE_ID = "javax.faces.component.UIInput.REQUIRED";
// Field descriptor #193 Ljava/lang/String;
public static final java.lang.String UPDATE_MESSAGE_ID = "javax.faces.component.UIInput.UPDATE";
I remark that the value of the String field is exactly the key that must be added in the resources.properties, like, for example, javax.faces.component.UIInput.CONVERSION.
For a new class, like, for example, javax.faces.validator.RegexValidator class, I will do the following: open it in class file editor, pick those fields whose name ends in _ID, like :
// Field descriptor #30 Ljava/lang/String;
public static final java.lang.String VALIDATOR_ID = "javax.faces.RegularExpression";
// Field descriptor #30 Ljava/lang/String;
public static final java.lang.String PATTERN_NOT_SET_MESSAGE_ID = "javax.faces.validator.RegexValidator.PATTERN_NOT_SET";
// Field descriptor #30 Ljava/lang/String;
public static final java.lang.String NOT_MATCHED_MESSAGE_ID = "javax.faces.validator.RegexValidator.NOT_MATCHED";
// Field descriptor #30 Ljava/lang/String;
public static final java.lang.String MATCH_EXCEPTION_MESSAGE_ID = "javax.faces.validator.RegexValidator.MATCH_EXCEPTION";
and add the following entries to the resources.properties file:
javax.faces.RegularExpression=custom message
javax.faces.validator.RegexValidator.PATTERN_NOT_SET=custom message
javax.faces.validator.RegexValidator.NOT_MATCHED=custom message
javax.faces.validator.RegexValidator.MATCH_EXCEPTION=custom message
Unfortunately, given the huge number of classes for which error messages must be provided, i don't find this as a feasible solution.
UPDATE
I just realized why only Conversion and Validation error messages should be provided: because they are related to user input, which the programmer cannot control. All the other errors like Navigation related issues must be properly handled by the programmer. Such errors should not appear in the first place, so it does not make sense to translate those messages anyway.
I am using SI 4.0 and trying to use object-to-map-transformer as below
<integration:object-to-map-transformer input-channel="inputChannel"
output-channel="outChannel" >
</integration:object-to-map-transformer>
I am sending a object like Person class on the inputChannel. But the moment I fire my test it fails with following error
Caused by: java.lang.IllegalStateException: Neither jackson-databind.jar,
nor jackson-mapper-asl.jar aren't presented in the classpath. at
org.springframework.integration.support.json.JacksonJsonUtils.<clinit>(JacksonJsonUtils.java:41)
I dont understand why it needs jackson. I looked at SI code and can see it needs Jackson class but why is this need - when I simply need to map a simple object to Map?
Thanks
The code to convert object to map looks like:
Map<String,Object> result = this.jsonObjectMapper.fromJson(this.jsonObjectMapper.toJson(payload), Map.class);
Since the out of the box implementation for the JsonObjectMapper is Jackson, it requires that the last one should be presented in the classpath.
We decided to use JSON notation for the Map presentation, since any object in JSON has map-based structure.
If you have another algorithm to do the same, the contribution is welcome!
Or you can simply implement your own Transformer with that logic and use it from generic <transformer>.
I'm using db4o with groovy (actually griffon). I'm saving dozen of objects into db4o objectSet and see that .yarv file size is about 11Mb. I've checked its content and found that it stores metaClass with all nested fields into every object. It's a waste of space.
Looking for the way to avoid storing of metaClass and therefore reduce the size of result .yarv file, since I'm going to use db4o to store millions of entities.
Should I try callConstructors(true) db4o configuration? Think it would help?
Any help would be highly appreciated.
As an alternative you can just store 'Groovy'-beans instances. Those are compiled down to regular Java-ish classes with no special Groovy specific code attached to them.
Just like this:
class Customer {
// properties
Integer id
String name
Address address
}
class Address{
String street;
}
def customer = new Customer(id:1, name:"Gromit", address:new Address(street:"Fun"))
I don't know groovy but based on your description every groovy object carries metadata and you want to skip storing these objects.
If that is the case installing a "null translator" (TNull class) will cause the "translated" objects to not be stored.
PS: Call Constructor configuration has no effect on what gets stored in the db; it only affects how objects are instantiated when reading from db.
Hope this helps
