Anatoly above sums it pretty clearly and nicely as to what you need to do.
If you are looking for a quick and dirty test try changing the hostnames from
http://config:8888 to http://localhost:8888
in the bootstrap.yml files, for the service you are trying to run.

If you build and run project modules manually (e.g. from IDE) you should rename all "config" hostnames in bootstrap.yml files to "localhost".
The issue is, this project uses Docker Compose to run things
Development mode
If you'd like to build images yourself (with some changes in the code, for example), you have to clone all repository and build artifacts with maven. Then, run docker-compose -f docker-compose.yml -f docker-compose.dev.yml up
docker-compose.dev.yml inherits docker-compose.yml with additional possibility to build images locally and expose all containers ports for convenient development.
and Docker Compose allows you to use service name as hostname.

Setting failsafe to false will just not throw the exception , this is something I would not recommend since this means even if you are not connected to your config server and unable to fetch the configuration your application will run which leads to an uncertain behavior (since you do not know where your properties are loaded), always better to fail fast.
The original cause of the problem is an exception or failing during fetching the remote environment from your config server, probably a timeout issue.

Your configuration is not setup properly. It thinks the hostname is 'config'.

For me it was because the Jhipster Registry was not running

I met this issue as the same, i resolved it by updated configuration below:
cloud:
config:
fail-fast: false

After changing Active profiles to local in "Edit configuration" it started working.
1)
2)

For Jhipster...
The focus is on http://localhost:8761/config, and then I saw that there is a bootstrap-prod.yml based on the production environment in the project. The reason is that the configuration in the production environment is the same as the dev, which leads to an error.
So replace the produced localhost with the domain name/IP of the project registration center

I got something similar, an 500 internal error from a micro service! No cause given.
I looked at the config server, for the service my application was attempting to contact. It had given a parse error when attempting to read a yml file at start up, with the result the entire process was hanging.
So if you get an error, look in the logging data from your config server, there might be some extra information there.

Grails 3.2.4 refuses to save domain instance: java.lang.IllegalArgumentException: object is not an instance of declaring class

I am upgrading from Grails 2.4.4 to Grails 3.2.4.
I have setup a few factories to help me with testing, the role factory works fine, which runs before the users get created. Then I have the following code:
println "create user."
def testUser = new User(username: 'admin#mail.com', firstName: "admin", lastName: "admin", email: "email#mail.com")
println "User. :: " + testUser
println "User class. :: " + testUser.getClass().toString()
println("User Errors: " + testUser.errors)
testUser.save()
println "create user2."
def testUser2 = new User(username: 'trade#mail.com', email: 'trade#mail.com', firstName: "trade", lastName: "trade").save()
Of which the output is:
create user
User. :: Person: admin#mail.com
User class. :: class UserManage.User
User Errors: grails.validation.ValidationErrors: 0 errors

The save method fails, and it is not due to validation errors.
My class structure is APEntity as an abstract class and the User class inherits from the APEntity class. This code works fine in Grails 2.4.4
Any suggestions where I can look to fix the error would be greatly appreciated.

The class instance being constructed is User but the type seen is UserManage.User
at UserManage.User.save(User.groovy)
In my experience Grails 3 is much more type-safe than Grails 2 and less forgiving for ambiguity. Be explicit: User a = new User()

It turned out that validation was the problem.
After I ensured that the types were correct, I disabled all of my constraints. Once the constraints were turned off the validation problem became apparent. In my situation, it was that in Grails 2 I would simply input a null value for a date that is not specified. In grails 3 it seems that this is not allowed, I thus gave it a default value and the validation problem was fixed.

Just to add my notes on this topic since this was the post that made me put a lot of focus in the wrong aspects causing the issue, in the hope to save others spending time trying to identify something that doesn't seem correctly defined.
input a null value for a date that is not specified
This isn't strictly true.
I spent ages attempting to track where the issue was created a dummy site under 3.2.8 and tried to recreate the hasMany and actual objects that had nullable true. If this had been the case then a lot of additional work to fill in nulls where not needed and ultimately filling DB with stuff not required and breaking other logics of the code.
Either way so far as I understand this issue is caused in grails 3.2 by two things so far :
https://github.com/grails/grails-core/issues/10428
This was when a domain class object had
String aUser
static constraints = {
aUser(nullable:true)
}
The above is already fixed in later versions of 3.2.X
A new issue hit recently https://github.com/grails/grails-core/issues/10600 when a domain object has _underscore
String _user
static constraints = {
_user(nullable:true)
}
This appears to be in for fixing and should hopefully be fixed for 3.9
Meaning if you have _objects it will be safe to say it is likely to break under 3.2.X > - < 3.2.8 (was working in 3.1.10).

Could someone help me, I'm very difficult to find a solution for this problem!!

This has been resolved. I ended up generating my own web service proxy services for the TaskService, instead of using the one that was bundled with jDeveloper. So honestly speaking, because of time constraints, I did not get a chance to fix the exact root cause of this error. After generating this webservice proxy/stub, i bundled it as a shared webapp library and my Custom Worklist portlet refers to this library. This worked for me.
I used this WSDL to generate the proxy classes and then used the generated classes/methods to query tasks data.
http://soa_host:soa_port/integration/services/TaskQueryService/TaskQueryService?wsdl
Also, later taking the original case forward, I was also able to get around the token problem by using RMI/EBJ provider ( t3://: ) instead of SOAP binding (http://:).
Here's what my code looks like :
String serverUrl ="t3://soa_server:soa_port"; // host:Port of the soa server
Map<IWorkflowServiceClientConstants.CONNECTION_PROPERTY, String> connProperties = new HashMap<IWorkflowServiceClientConstants.CONNECTION_PROPERTY, String>();
connProperties.put(IWorkflowServiceClientConstants.CONNECTION_PROPERTY.CLIENT_TYPE,WorkflowServiceClientFactory.REMOTE_CLIENT);
connProperties.put(IWorkflowServiceClientConstants.CONNECTION_PROPERTY.EJB_PROVIDER_URL,serverUrl);
connProperties.put(IWorkflowServiceClientConstants.CONNECTION_PROPERTY.EJB_INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
IWorkflowServiceClient wfSvcClient = WorkflowServiceClientFactory.getWorkflowServiceClient(connProperties, null, null);
ITaskQueryService querySvc = wfSvcClient.getTaskQueryService();
IWorkflowContext adminCtx = wfSvcClient.getTaskQueryService().authenticate(adminID, adminPass.toCharArray(), "jazn.com" );
IWorkflowContext userCtx = querySvc.authenticateOnBehalfOf(adminCtx, userID);
List displayColumns = new ArrayList();
displayColumns.add("TASKNUMBER");
displayColumns.add("TITLE");
displayColumns.add("STATE");
displayColumns.add("CREATOR");
List optionalInfo = new ArrayList();
optionalInfo.add("Comments");
optionalInfo.add("Payload");
tasks=querySvc.queryTasks(userCtx, null, null, ITaskQueryService.AssignmentFilter.MY,null, null, null, 0, 0);
This returns list of tasks assigned to the user whose ID you send to authenticateOnBehalfOf() method call above.
I hope this helps.

Below solution from Oracle Support Documentation fixed the issue for me. In summary, it's a jar mismatch between server and jdev that caused the issue.

Cause
The bpm-services.jar on the client application and the server may not match. The SOA/BPM related jars being used on the client and server must be the same or unexpected issues can occur.
Solution
Copy the bpm-services.jar from the server
Replace the bpm-services.jar on the client application with the one from the server
Ensure that after any patches are applied that the jars on the server are replaced in the client application.
This also applies to using jars within JDeveloper which can become out of sync due to patches not being applied on both dev and server machines. You may need to replace the bpm-services.jar located here JDeveloper/soa/modules/oracle.soa.workflow_11.1.1/bpm-services.jar with the one located here [soa_install_dir]/soa/modules/oracle.soa.workflow_11.1.1/bpm-services.jar.

How can i read extended file attribute in Java?

I have file with extended attribute user.MYATTR
when I run command: getfattr fileName -d, I get this:
user.MYATTR="attribute_value"
My OS is Red Hat Enterprise Linux Server release 6.4 (Santiago)
but when I am running my Java code
LOG.debug("readExtentedAttribute(path={},name={}", path, name);
UserDefinedFileAttributeView view = Files.getFileAttributeView(path, UserDefinedFileAttributeView.class);
ByteBuffer buffer = ByteBuffer.allocate(view.size(name));
view.read(name, buffer);
buffer.flip();
String value = Charset.defaultCharset().decode(buffer).toString();
LOG.trace("extended attribute value = {}", value);
I am getting exception
java.nio.file.FileSystemException: /opt/myfolder/myfile: Unable to get size of extended attribute 'user.MYATTR': No data available

Finally I found that when I want to read attribute user.MYATTR, i have to use name MYATTR.
I just wanna mention what interesting behaviour I found, that may lead to mystakes and i wanna warn you :)
My file has these two attributes:
user.MYATTR1
user.somethingElse.MYATTR2
When I was listing attributes using view.list() method I saw only this one (without user.):
MYATTR1
when i wanna read attribute value, i have to use name of attribute without 'user.', so for mentioned attributes it is:
MYATTR1
or
somethingElse.MYATTR2

Did you read the docs to the class UserDefinedFileAttributeView?
Reading carefully gives a few hints, why your code doesn't work properly.
For example you can check that:
... This FileAttributeView is not intended for use where the size of an
attribute value is larger than Integer.MAX_VALUE ...
or check, if you have a security manager installed:
... in the case of the default provider at least, all methods that
access user-defined attributes require the
RuntimePermission("accessUserDefinedAttributes") permission when a
security manager is installed. ...
Or try out another method to get an attribute:
... Where dynamic access to file attributes is required, the
getAttribute method may be used to read the attribute value. The attribute value is returned as a byte array (byte[]). ...
Maybe any of the hints helps you, good luck! :-)
EDIT
Here's an example code, which checks, if your file system provides user defined file attributes and prints them (on succes):
Path file = Paths.get("filename.ext");
// check that user defined attributes are supported by the file system
FileStore store = file.getFileStore();
if (!store.supportsFileAttributeView("xattr")) {
System.err.format("UserDefinedFileAttributeView not supported on %s\n", store);
System.exit(-1);
}
UserDefinedFileAttributeView view = file.getFileAttributeView(UserDefinedFileAttributeView.class);
// list user defined attributes
if (args.length == 1) {
System.out.println(" Size Name");
System.out.println("-------- --------------------------------------");
for (String name: view.list()) {
System.out.format("%8d %s\n", view.size(name), name);
}
}
Full source code here linked from this page your question code is from ;-)

Spring will be checking the security roles and throwing an exception before executing the handler.
You would normally be able to catch this exception in the client onFailure() method of the Request but the exception thrown may not be serialisable or most likely not available to the GWT client side code and cannot be serialised - leading to the error.
It looks like you are using the gwt-dispatch library? I haven't used this for some time but you can override the SpringSecureDispatchServlet and add your own implementation of the doUnexpectedFailure(Throwable e) method. In there you could check the exception to see if it is a Spring security exception and instead of calling RPCServletUtils.writeResponseForUnexpectedFailure(...) that returns a status code of 500 implement your own that returns a more suitable error code (401, or 403).

Couldn't you add a Servlet Filter to catch this particular exception and turn it into the HTTP response you would like?
