Re: Getting isis working with Intellij

[Vladimir Nišević]

Hi, in company I am working in, we have many developers using Apache Isis
with their favorite IDE, either Eclipse or IntelliJ. Both ways pretty
straight forward.

Your screenshots are removed, probably by mailing list server, so it is
hard to support with no information.

Re: Major changes with Isis v2

[Vladimir Nišević]

Hi Andi, I am really looking forward to this feature! In the past I had lot
of discussions regarding using Isis framework instead of Spring
Boot/JPA/Hibernate. Having this possibility I guess I will get best of both
worlds.

What I currently really like about Isis is the possibility of using domain
services in entities by injection, and not to trap into "anemic domain
model anit-pattern" [1]. Would be interesting to understand how you plan to
support this feature in the future?

In my current projects, some developer argue that one of the weaknesses in
Isis is missing support of nested transaction. Any plans to address this
capability?

Thanks
Vladimir

Re: Warning a user based on input on action invocation

[Vladimir Nišević]

Yes, this feature would be great one!

In one application (non Isis but Eclipse RCP) we developed times ago, we
had UI style guide where each input field can have
warning/information/error depending on current user input (ideally giving
feedback on each keystroke or when list selection happened).
Additionaly,  whole dialog (if modal) can provide same feedback to user,
when e.g. multiple input values in their combination lead to invalid
state...

Would be interesting if this feedback/validation could be (partially?)
delegated to browser JS engine and so reduce network overhead but at the
same time keeping the beauty of Isis programming model?

Re: Support for nested transactions

Yes, we tried already with TransactionsService but this is not enough since
this supports only one at the time.

We will go for the solution using AbstractIsisSessionTemplate!

Support for nested transactions

[Vladimir Nišević]

Hi folks, as I understand, Isis supports by default one JDBC transaction at
time as part of single IsisTransaction and single IsisSession.

We have a case where we would need nested JDBC transactions or multiple
parallel transactions where some of the transactions we would need to
rollback and some of them commit.

Any ideas how to achieve this


Kind regards

How to use alternative in memory database for Integration/Cucumber tests

[Vladimir Nišević]

Dear Isis community, we have upgraded to Isis 1.16.2 and now we are forced
to use HSQL-DB as in-memory database.

Here the code from isis-core-runtime-1.16.2.jar which is responsible for
that


package org.apache.isis.core.runtime.headless;
...
public class IsisSystemBootstrapper {


private static IsisSystem setupSystem(final AppManifest2 appManifest2) {

final IsisConfigurationForJdoIntegTests configuration = new
IsisConfigurationForJdoIntegTests();

configuration.putDataNucleusProperty("javax.jdo.option.ConnectionURL","jdbc:hsqldb:mem:test-"
+ UUID.randomUUID().toString());
final IsisSystem.Builder isftBuilder =
new IsisSystem.Builder()
.withLoggingAt(org.apache.log4j.Level.INFO)
.with(appManifest2)
.with(configuration);

IsisSystem isft = isftBuilder.build();
isft.setUpSystem();

// save both the system and the manifest
// used to bootstrap the system onto thread-loca
IsisSystem.set(isft);
isftAppManifest.set(appManifest2);

return isft;
}

Since we had in the past issues with HSQL-DB (sequences are sometimes
generated in PUBLIC scheme and not accessible from datanucleus persistence)
we have moved to H2 database, it seems to be more robust,

But since upgrade to 1.16.2 we are forced to use HSQLB in
Integration/Cucumber tests.

Any hints how to change this?

Re: Chat

Hi, for this purpose we usually introduce for a separate domain service,
use it's lifecycle ( described here
https://isis.apache.org/guides/ugfun/ugfun.html#_ugfun_programming-model_domain-services_initialization
) to initialize/shutdown connectivity the service and implement actions to
be used by rest of domain model.

I this way we did connectivity to Elastic, JMS, additional Databases etc.

SimpleApp has isis.properites at two places

[Vladimir Nišević]

Hi, I've just noticed, that in the latest simpleapp (1.15.1) created from
archetype there is a file "isis.properties" at two places and it seems that
we need them at both:

   1.
   
simpleapp\application\src\main\resources\domainapp\application\manifest\isis.properties
   2. simpleapp\webapp\src\main\webapp\WEB-INF\isis.properties


Additionaly, the second file contains now the database configuration but
there is also a file
'simpleapp\application\src\main\resources\domainapp\application\manifest\persistor_datanucleus.properties'
where datanucleus configuration is also defined.

For me this is confusing and hard to manage because we have now generally
speaking three times isis.properties:

* two times packaged in the war as desribed and
* third time when we use externalized configuration, because ususally we
exchange war file but environment-specific configuration is stores
separately.

What if a single configuration is stored in all three files, which takes
precedence?

Re: Using view model as parameter in restful inteface

Hi Dan, thanks for your hints!
We have solved it so that we pass single string parameter containing
multiple strings concatanated by a special character. So we have built an

Re: Getting "Header is too large 8193>8192" exception when using larger view models

[Vladimir Nišević]

Hi Dan, thanks for your input, will try this out, although I didn't
understand yet how it helps.
I don't generally understand how is the lifecycle of view model, do you
hold them in server session, Or forward them marshalled to browser and then
back to server, or even both?

Alternatively I found that different servers (Tomcat,  Jetty) have
different default maximum request size.  Jetty has default 8192 bytes, but
there is a possibility to adapt it.

So alternative would be to pass higher value to org.apache.isis.WebServer
so it can launch embedded Jetty with higher value?
Would also try in this direction and if successful would propose a PR.

Thanks,Vladimir

Getting "Header is too large 8193>8192" exception when using larger view models

[Vladimir Nišević]

Hi, my view models seems to be such large that I get now the exception
"Header is too large 8193>8192" when browser submits e.g. an action from
rendered view model to server running on jetty.

Is this a jetty-specific issue is has generally related with the fact that
view model is marshalled into GET parameter.

Any idea how to solve this?


Thanks

Using view model as parameter in restful inteface

[Vladimir Nišević]

I must provide a REST service accepting more complex view model as input
parameter.

My view model parameter would look like

@DomainObject(nature = Nature.VIEW_MODEL, objectType = "OfferTemplateFilter")
@XmlRootElement(name = "OfferTemplateFilter")
@XmlAccessorType(XmlAccessType.FIELD)
@Getter @Setter
public class OfferTemplateFilter {

public OfferTemplateFilter() {
}

public List selectedDeviceManufacturer = new ArrayList<>();

public List selectedDeviceSizes = new ArrayList<>();

}

My REST domain service would be someting like

@DomainService(nature = NatureOfService.VIEW_REST_ONLY, objectType =
"OfferRestService")
public class OfferRestService {

 @Action(semantics = SemanticsOf.IDEMPOTENT)
public OfferTemplateSelectorForCustomer
offerSelectorForCustomer(final String subscriberNumber, final
OfferTemplateFilter filter) {
return offerSelectorRepository.create(subscriberNumber, filter);
}

 
}


I'm wondering how this could be achieved without custom rest service.
Ideally the service consumer would post a kind of JSON structure where my
view model OfferTemplateFilter would be created?

Any hint on this?

Thanks
Vladimir

Re: Addon module isis-module-settings is not working after upgrade to Isis 1.15.0

[Vladimir Nišević]

Hi Dan, sorry, you are right, I missed to push the changes. Meanwhile they
should be there.

Reproduce the bug:

-  Create new "Application Setting" or "User Setting" of type e.g. String.


Thanks
Vladimir

Addon module isis-module-settings is not working after upgrade to Isis 1.15.0

[Vladimir Nišević]

Hi, I have an issue with latest Isis version 1.15.0 and module
isis-module-settings (in both addon versions, 1.15-SNAPSHOT and  1.14.0)

How to reproduce:

* Integrate addon with simpleapp
* Try to create an Application Settings "New String"

Here my fork with simpleapp and addon:
https://github.com/niv0/isis/tree/simpleapp-with-settings-addon

Specifying cssClass in runfime?

[Vladimir Nišević]

Hi, I have a requirement to present the background of specific property
based on its value or depending on other object properties. Currently I can
define cssClass as described
https://isis.apache.org/guides/ugfun/ugfun.html#_ugfun_ui-hints_action-icons-and-css
at development time.

It would be great if I could define a kind of specification class similar
to
https://isis.apache.org/guides/rgant/rgant.html#_rgant-Property_mustSatisfy
which returns cssClass in runtime.

It could look like this

public class Customer {
@Property(cssSpecification=MyCssClass.class)
public String getFirstName() { ... }
...
}



public class MyCssClass implements CssSpecification {
public String cssClass(Object obj) {
if (((Customer) getFirstName())==null)
  return "x-test";
return "x-firstName-not-empty";
}
}


Make this requirement sense, and if so, any hints how I could implement
this?

Regards,Vladimir

Issue with auto-reload - getXxx properties not updated

[Vladimir Nišević]

Hi, I am trying to implement auto-refresh feature following the guide (
https://isis.apache.org/guides/ugvw/ugvw.html#_ugvw_customisation_auto-refresh
) and have an issue there.

I have implemented my own HomePage view model, this has an getXxx method
representing an field showing in the home page.

@DomainObject(nature = Nature.VIEW_MODEL, editing = Editing.DISABLED,
objectType = "StandardHomePage")
public class StandardHomePage  {

public StandardHomePage() {
}

public String cssClass() {
return "my-special-auto-updating-entity";
}

...

@PropertyLayout(named = "Hupe Status")
@MemberOrder(name = Layout.LAYOUT_HORN, sequence = "4.1")
public String getCurrentHornState() {
TitleBuffer titleBuffer = new TitleBuffer();
final SignalHorn horn = deviceRepository.getSignalHorn();
if (horn == null)
return "Hupe nicht vorhanden";
return horn.title();
}

...

}

I create home page thru domain service


@DomainService(nature = NatureOfService.VIEW_CONTRIBUTIONS_ONLY)
public class HomePageService {

//region > homePage (action)
@Action(semantics = SemanticsOf.SAFE)
@HomePage
public BgwHomePage homePage() {
   return new StandardHomePage();
}

And my application.js looks

$(function() {
if ($(".my-special-auto-updating-entity").length) {
setTimeout(function() {document.location.reload(true);},
15000); // 1000 is 1 sec, 30 sec
}
});


In debugger I observe that StandardHomePage constructor and getXxx
method is called differently:

1. after login browser goes to e.g.
http://localhost:9090/wicket/entity?2  and auto-reload after e.g. 15
seconds calls only constructor but not the getXxx method
3. after clicking on upper-left hand side icon representing the home
page I get the again the url e.g..
(http://localhost:9090/wicket/entity?32) and the auto refresh calls
only the constructor
4. after clicking on home page title - browser URL shows reference to
that view model  (something like
http://localhost:9090/wicket/entity/*StandardHomePage:PD94bWwgdmVyc2lvbj0iMS4wIiBlbmNvZGluZz0iVVRGLTgiPz4KPG1lbWVudG8vPg==)
and constructor and getXxx method are called, and after that the auto
refresh behaviour is fine.

My problem are case #1 and #2  where method getXxx is not called - I
guess the view model is being deserialized for memento.

How can I fix this and prevent usage of serialized view model
representing the home page?

I am working with Isis version 1.14.x

Thanks,Vladimir

Re: Issue in isis-module-security - in combination with delegateAuthenticationRealm

Hi Dan, here the adapted file

I've made also an PR, but somehow it was mixed up with some previous PR
which is still pending on github.


The behavior is configurable thru next property in shiro.ini

Issue in isis-module-security - in combination with delegateAuthenticationRealm

[Vladimir Nišević]

Hi, I am using security module in combination with our Active Directory:

   1. Roles and delegate users (without passwords) are created in Isis
   security module
   2. Authentication is done thru company Active Directory


I think, I've found an issue in this setup: As part of login procedure, if
the user doesn't exist in Isis security, it will be automatically created
as new delegate user (with Status=Disabled). This leads to potentially many
users in security module, every time when somebody e.g. mistypes the
username.


Here my shiro.ini

*[main]*
*isisModuleSecurityRealm =
org.isisaddons.module.security.shiro.IsisModuleSecurityRealm*
*authenticationStrategy =
org.isisaddons.module.security.shiro.AuthenticationStrategyForIsisModuleSecurityRealm*
*securityManager.authenticator.authenticationStrategy =
$authenticationStrategy*
*securityManager.realms = $isisModuleSecurityRealm*
*isisModuleSecurityRealm.delegateAuthenticationRealm=$activeDirectoryRealm*
*activeDirectoryRealm =
org.apache.shiro.realm.activedirectory.ActiveDirectoryRealm*
*activeDirectoryRealm.searchBase =*
*activeDirectoryRealm.url = **

I think the bug is in the class

org.isisaddons.module.security.shiro.IsisModuleSecurityRealm

line 48:
*  PrincipalForApplicationUser principal = this.lookupPrincipal(username,
this.hasDelegateAuthenticationRealm());*

it should be:
* PrincipalForApplicationUser principal = this.lookupPrincipal(username,
false);*

Or was it on purpose to auto create new delegate user on every login
attempt?

Re: Simpleapp 12.0.1. - Swagger not working when packaging war and deploying to Tomcat

[Vladimir Nišević]

Hi Dan, thanks for the advice!

We have a multiple stages for our system (Dev PC, DEV, INT, PROT),  the
context root value changes - at least between developer pc and deployment
on Tomcat.

Developer PC:
No context root since running with embedded jetty - no adaptations needed
for swagger-ui/index.html and web.xml

DEV, INT:
There is a context root e.g. "simpleapp" - adaptations needed in
swagger-ui/index.html
and web.xml


Any idea how to make that configurable so that swagger works in both cases?

Thanks,Vladimir

Simpleapp 12.0.1. - Swagger not working when packaging war and deploying to Tomcat

[Vladimir Nišević]

Based on discussion in https://issues.apache.org/jira/browse/ISIS-1358 I
think I've found an issue, but I cannot create new JIRA issue any more -
seems the issue creation policy has been changed, so I am sending the issue
on this way.

*Steps to reproduce:*

1. Create archetype as described in guide
*mvn archetype:generate \*
*-D archetypeGroupId=org.apache.isis.archetype \*
*-D archetypeArtifactId=simpleapp-archetype \*
*-D archetypeVersion=1.12.1 \*
*-D groupId=com.mycompany \*
*-D artifactId=myapp \*
*-D version=1.0-SNAPSHOT \*
*-B*

2. execute "*mvn clean package"*

3. deploy simpleapp.war to external tomcat, eg. thru tomcat manager webapp
and call swagger WebUI*
http://localhost:8080/simpleapp/swagger-ui/index.html
 *

*Error*: Can't read swagger JSON from
http://localhost:8080/restful/swagger/public

It seems that the service
org.apache.isis.core.metamodel.services.swagger.SwaggerServiceDefault is
not recognized.

Upgrade to 12.0.1 - Apache Isis Maven plugin "validate goal" needs dom or app module? Validation when Isis Addon is used?

[Vladimir Nišević]

Hi, after upgrading to 12.0.1 and  when "mvn clean install"  i get exception

*[ERROR] Failed to execute goal
org.apache.isis.tool:isis-maven-plugin:1.12.1:validate (default) on project
my-dom: Execution default of goal
org.apache.isis.tool:isis-maven-plugin:1.12.1:validate failed: The class
'my.app.MyAppManifest' cannot be found -> [Help 1]*


I use same skeleton as simpleapp:

* my.app.MyAppManifest is part of app module "my-app"
* validate profile is defined in pom.xml of dom module "my-dom"


Looking the documentation  "validate goal"
https://isis.apache.org/guides/rgmvn.html#3.-validate-goal and comparing it
with the generated simpleapp 12.0.1 it's not clear where the validate
profile should be? In the dom or in the app module?


When I move the validate profile to pom.xml of app module and restart  "mvn
clean install" on parent, validation seems to run but I get another error.


*[ERROR] Failed to execute goal
org.apache.isis.tool:isis-maven-plugin:1.12.1:validate (default) on project
my-app: Execution default of goal

I do use Isis Adon Setting and configure it in AppManifest in
getModules()-method.

Re: collection of similar types

[Vladimir Nišević]

Hi, I have perhaps similar issue.

I have an object (Order) which contains a list of objects can be different
type but all extend from the same superclass (Step). When I execute the
action on order thru wicket UI, the properties of concrete classes
StepType1 and StepType2 are not loaded. When I do the same thru
Intergration Test, the values are there?


*class Order{*
*.*
*//region > steps (collection)*
*@Column(allowsNull = "true")*
*@Persistent(mappedBy = "order", defaultFetchGroup = "true")*
*private List steps = new ArrayList<>();*

*@Collection(editing = Editing.DISABLED)*
*@CollectionLayout(render = RenderType.EAGERLY)*
*public List getSteps() {*
*return steps;*
*}*

*public void setSteps(final List steps) {*
*this.steps = steps;*
*}*
**
*}*


*abstract class Step{*
**
*//region > order (property)*
*@Persistent(defaultFetchGroup = "true")*
*@Column(allowsNull = "false")*

Re: collection of similar types

[Vladimir Nišević]

Hi Dan, when I execute the action on order the steps instances are there,
but the values of its properites are definitely empty - I've checked it
thru debugging of webapp. When I open a view of single step, the values of
that step are there.

I do not need to show additional values in a table, but have a problem with
business logic when executing an action which uses a data on single step.

Any idea?
Thanks, Vladimir

Re: New and better view models coming in 1.11.0-SNAPSHOT

[Vladimir Nišević]

Hi Dan, thank you, this is a really cool feature! The applications I'm
building, have often legacy systems and some parts of my domain models are
built on service calls to that legacy systems - in that case we build
domain models with view models to hold the data from multiple backends and
implement the core domain logic in them. Until now we have primarily used
this domain models to expose REST services to other systems, but I believe
this could be the way to implement some wicket based UI's.

Additionaly, here some ideas I'd like to share, maybe to see some of them
in the future in the Apache Isis framework:

1. Search capability based on e.g. Elasticsearch [1], where the
Elasticsearch could act as a kind of "external index" for the parts of
domain model. Developer could mark which fields should be searchable, this
fields would be updated in elasticsearch instance after database
insert/update/delete. User can search thru Elasticsearch and retreive the
entity OID's as results and in the second step use them to retreive the
entities from main repository (thru datanucleus container). I could
contribute to this feature since we have integrated Elasticsearch with
Apache Isis.

2. An add-on to support system-wide and/or user-specific notifications
(similar to Atlassian Confluence [2}). An Isis user could receive such
"notifications" - they would appear on his desktop, he could mark them
 "readed". Some notifications could be system-wide and controlled by e.g.
system without a possibility to remove them until e.g. administrator
decides that. We use such features  to e.g. notify application users there
is a newer version of the application and they should finish their work and
log off /logon in order to switch to that new version.

3. In a world of collaboration systems there could be an interest extension
to your incode-module-note feature, the capability not only to add the
notes to an entity, but also to add infinite comments to that note (in
other words to add the comment threads to the entity). In combination with
text search capability (idea #1) I thinks we could build really great
features.

Re: Neo4j and Apache Isis

[Vladimir Nišević]

Hi Dan, I've just tried out this example but have problems when opening the
neo4j server http://localhost:7474/

I've started the app thru webapp  - Run maven - jetty:run and Isis starts
fine.

Run Fixture scripts works as well, I see sample Hosts entites created..

Do I have to start the neo4j server separately?

 in case you're interested in such things, we now have a functioning example
 of Apache Isis running against neo4j (using 1.9.0-SNAPSHOT).

 Take a look at the screenshots, if nothing else [1]

Hi Dan, I've just went thru your guide and want to give you my feedback.

After the described steps how to setup the idea in the step maven helper
plugin https://isis.apache.org/guides/cg.html#_maven_helper_plugin you
assume from chapter 2.1.2 that the Isis source code is already checked out
locally.

Maybe you should spend some words here about how to get the current Isis
source code:

- install a git client (sourcetree
https://www.atlassian.com/software/sourcetree/overview ) or howto configure
a git in Idea
- checkout the Isis source code (refer to your documentation later

 Sounds ok... though what approach are you taking for transaction management?
 
I manage transactions to other databases manually, in case of any exception, I 
use process entity stored in Isis RDB to report exceptions

 Normally Isis does the xactn mgmt for free.  I guess you are doing that
 stuff yourself?  And (since we don't provide any hooks) presumably there is
 no 2PC/XA stuff, so there are possibilities of data being committed to one
 database but not the other?

Exactely! I can live with that, although it would be good to have automatic 
transaction begin/commit for other DB's like Isis does it.

Re: Validate method not working

[Vladimir Nišević]

Hi Gabriel, just tried your code with DomainService Categories

package dom.simple;

import org.apache.isis.applib.DomainObjectContainer;
import org.apache.isis.applib.annotation.DomainService;

@DomainService
public class Categories {

public Category newCategory(
String name,
Double price) {
Category aCategory = container.newTransientInstance(Category.class);
aCategory.setName(name);
aCategory.setPrice(price);
container.persist(aCategory);
container.flush();
return aCategory;
}

@javax.inject.Inject
private DomainObjectContainer container;

}


You can create negative price, since there is no validation in newCategory,
but when you open the object view, edit object and try to type negative
value, validation will work.

Fwd: Entity action with Clob parameter thru restful service

[Vladimir Nišević]

Hi there, here my question I've posted in isis dev mailing list. Probably it is 
isis-users question.
Maybe someone can help me with a hint.

 Betreff: Entity action with Clob parameter thru restful service
 
 Hi, we want to expose upload file feature of an entity thru restful interface.
 
 According to restful spec https://github.com/danhaywood/restfulobjects-spec 
 it should go like this:
 
 16.2.2 Request (if blobClobs)
 Updating blobClob properties is performed by PUTting the actual value
 (e.g. image), with appropriate content type.
 Note that optional validation (x-ro-validate-only) and domain type
 metadata preferences (x-ro-domain-model) are not supported for
 blobClobs.
 16.2.2.1 Query String
 · none
 16.2.2.2 Headers
 · Content-Type: (depends on property type)
 o eg image/jpeg, image/png, application/pdf
 · If-Match
 o timestamp digest
 
 obtained from ETag header of representation
 
 only validate the request, do not modify the property
 16.2.2.3 Body
 · a byte array (for blobs)
 · a character array (for clobs)
 
 So our method signature is:
 
   public String uploadFile(Clob input) { }
 
 And calling restful description of single entity we get
 
 ...
 uploadFile: {
 id: uploadFile,
 memberType: action,
 links: [
 {
 rel: urn:org.restfulobjects:rels/details;action=\uploadFile\,
 href: 
 http://localhost:8080/restful/objects/ASE_BATCH_JOB/L_2354/actions/uploadFile;,
 method: GET,
 type: 
 application/json;profile=\urn:org.restfulobjects:repr-types/object-action\
 }
 ]
 }
 ...
 
 and  in the next step we have
 ...
 {
 rel: urn:org.restfulobjects:rels/invoke;action=\uploadFile\,
 href: 
 http://localhost:8080/restful/objects/ASE_BATCH_JOB/L_2354/actions/uploadFile/invoke;,
 method: POST,
 type: 
 application/json;profile=\urn:org.restfulobjects:repr-types/object-action\,
 arguments: {
 clob: {
 value: null
 }
 }
 },
 ...
 
 So we have playing around with executing the methods thru e.g. postman 
 (chrome app), but with no success.
 
 Here our questions:
 
 1. URL should be something like: 
 http://localhost:8080/restful/objects/ASE_BATCH_JOB/L_2354/actions/uploadFile/invoke
  - this is pretty clear, I think...
 
 2. Should we send PUT or POST Request ?
 
 3. May we define a method with return value, e.g. String, or must be void?
 
 4. Should we annotate our method  with @Action(semantics = 
 SemanticsOf.NON_IDEMPOTENT) ? Without annotations, Isis proposes the POST
 
 5. We put in request header 
 
 Content-Type:text/plain
 
 Should we put something else/more? If-Match element? If yes which value? *
 
 6. How the request body should look like?
 
 6a: raw text ? e.g. ABC
 
 6b: Json clob representation from previous description response
 {
 clob: {
 value: ABC
 }
 }
 
 6c: Json value 
 
 {
 value: ABC
 }
 
 
 Depending on request variants, we get different exceptions. So we are not 
 sure if we use it wrongly or we have a bug...
 
 
 
 Thanks,Vladmir
 
 

Re: Entity action with Clob parameter thru restful service

[Vladimir Nišević]

Hi Martin, thank you for your reply. Meanwhile I've made it.

Here my method on e.g. SimpleObject

*  @org.apache.isis.applib.annotation.MemberOrder(sequence = 5.1)*
*@Action(semantics = SemanticsOf.NON_IDEMPOTENT)*
*public void uploadFile(final Clob input) {*
*logger.info http://logger.info(Uploaded file details: \nName: 
+ input.getName() + , MimeType:  + input.getMimeType() + , Length:  +
input.getChars().length());*
*}*


After sending the post request

*URL:
 http://localhost:8080/restful/objects/SIMPLE/L_0/actions/uploadFile/invoke
http://localhost:8080/restful/objects/SIMPLE/L_0/actions/uploadFile/invoke*
*No specific headers like e.g. ContentType*
*Body: {clob:{value: test.txt:text/plain:abc}} *

I've got the correct instantiated Clob object as action parameter.


Thank you for your support!

@Dan: I'm not sure if the RO spec in this case is up to date.

 Agreed! Look correct!


  
   2. Should we send PUT or POST Request ?
 

 Use PUT for idempotent operations and POST for non-idempotent


  
   3. May we define a method with return value, e.g. String, or must be
  void?
 

 #uploadFile() is an action with a parameter (the Clob).
 I am not sure about restful.
 Wicket viewer will use the return type to render the result of the action.
 I guess restful will do something similar, i.e. will render a String or an
 empty response with code 200.


  
   4. Should we annotate our method  with @Action(semantics =
  SemanticsOf.NON_IDEMPOTENT) ? Without annotations, Isis proposes the POST
 

 See 2.


  
   5. We put in request header
  
   Content-Type:text/plain
  
   Should we put something else/more? If-Match element? If yes which
 value?
  *
 

 I guess you mean If-None-Match - this should be used for GET requests so
 the server can decide whether to stream the body or just response 304 (non
 modified).
 The content-type value will be put in Clob#contentType, I guess.


  
   6. How the request body should look like?
  
   6a: raw text ? e.g. ABC
 

 yes, if content-type is text/plain


  
   6b: Json clob representation from previous description response
   {
   clob: {
   value: ABC
   }
   }
  
   6c: Json value
  
   {
   value: ABC
   }
 

 6c looks correct if content-type

Re: Using property files to setup IsisSystemForTest

[Vladimir Nišević]

Hi Jeroen, was actually a bad idea.

Thanks,Vladimir

2014-11-24 15:15 GMT+01:00 Jeroen van der Wal jer...@stromboli.it:

 Hi Vladimir,

 The isis.properties you want to point to lives in a different project and
 might have a different purpose so you should rather not create and
 inter-project dependency like that. Also your example uses a resource
 location which is specific to your machine which is a pain if you want to
 have another developer work on the same code base.

 In general there are only a few properties you need to set in ISFT since
 most domain services are automatically discovered by the @DomainService
 annotation. We've had no requirement to use isis.properties in our
 integtest projects so far, perhaps you can share the reason why the current
 situation doesn't work for you?

 Cheers,

 Jeroen

Wicket viewer - Clob/Blob as return value of an domain service action, download file...

form menu) with an Clob return value

e.g.

String content = HiThere;

Would expect to get an Save As dialog to store a file.

Would that make sense?

Usage of multiple DomainObjectContainers ?

[Vladimir Nišević]

Hi guys, I have a requirement where parts of my domain objects come from
different sources.

a. reational database
b. elasticsearch (accessible thru REST interface)

What would be a feasible approach?

My first idea was to introduce a view models and instantiate them manually
and fill them from RDB and Elasticsearch sources. A kind of anticorruption
layer?

Or should I implement additional DomainObjectContainer interface (
https://isis.apache.org/reference/DomainObjectContainer.html ) for
elasticsearch?

Can I use multiple domain object container implementation at the same time?

Regs,Vladimir

Re: Usage of multiple DomainObjectContainers ?

[Vladimir Nišević]

Hi Dan, thanks for your feedback, I'll stick to my first idea, and as soon
I have something to share, will definitely come back to you.


Nevertheless, I have some show-stoppers there:

1. View model representation in wicket viewer - please check my latest
comments on  https://issues.apache.org/jira/browse/ISIS-899
2. View model entity referencing another view model entity - check also
same issue



3. Also have another question / feature request regarding restful viewer.

My service consumer needs actually simplified JSON response.  I guess I
would need a kind simplified rest viewer?

Regs,Vladimir



Here my spec by example:


*Given two view model objects and domain service returning instance of A.*

@ViewModel
Class A {

private int id;

private String a1;

private B b1;

}


@ViewModel
Class B {

private int id;
private String c1;
}

*when a 3rd party service consumer calls the domain service method
getForExample() thru restful invoke API*

@DomainService
public class Service1 {

public A getForExample() {
...
}
}

*then the answer should be a simple JSON structure representing only the
parameters of the objects*

{
id: 123,
a1: someTextHere,

b1 : {

c1: someAnotherTextHere

}

}






2014-10-01 9:50 GMT+02:00 Dan Haywood d...@haywood-associates.co.uk:

 Hi Vladimir,

 I would go with your first idea; this sort of side-loading approach
 should work fine.

 If you end up with anything that is reusable, please consider creating a
 github repo so that we can (at minimum) fork it into isisaddons [1]

Hi Dan, yes I saw the Settings add-on.  Bur I need to use the configuration 
parameter when instantiating my domain service (Isis biotstrap?). 

As far I understand,the way would be to use ApplicationSettingsService 
(https://github.com/isisaddons/isis-module-settings/blob/master/dom/src/main/java/org/isisaddons/module/settings/dom/ApplicationSettingsService.java
 )

What I don't undersand is the order

early Isis bootstrapping phase?

Hope I explained this clearly...

 Hi guys, I have question how to deal with application specific

 I use elasticsearch to put/get specific documents and use them in a

 So I defined a domain service EsClient to access to elasticsearch - I
 use service lifecycle to connect/disconnect to elasticseach.
 
 
 
 According to ((

 - put the configuration parameters into isis.properites
 - get the parameter value in a domain service by
 container.getProperty(propertyName);
 
 Currently I get null value here...

 When you add an init method which takes a map of  tow strings as the

 Hi Dan, yes I saw the Settings add-on.  Bur I need to use the
 configuration parameter when instantiating my domain service (Isis
 biotstrap?).
 
 As far I understand,the way would be to use ApplicationSettingsService (
 https://github.com/isisaddons/isis-module-settings/blob/master/dom/src/main/java/org/isisaddons/module/settings/dom/ApplicationSettingsService.java
 )
 
 What I don't undersand is the order
 how Isis creates the domain services. Can I use the AppSettigsService in
 this early Isis bootstrapping phase?
 
 Hope I explained this clearly...

 Hi Vladimir,
 
 Not quite sure how the second doc helped you, but perhaps I misunderstood
 your original question.
 
 But at any rate, if you want to do is to store application-settings, then
 check out the Settings module add-on [1]...  that'll let you store such
 stuff in the database.
 
 Other add-ons listed at [2]
 
 Cheers
 Dan

 Hi guys, I have question how to deal with application specific
 configuration parameters...
 
 
 I use elasticsearch to put/get specific documents and use them in a
 domain
 model.
 
 So I defined a domain service EsClient to access to elasticsearch - I
 use service lifecycle to connect/disconnect to elasticseach.
 
 
 
 According to ((
 https://isis.apache.org/reference/configuration-files.html)
 ) my first idea was to:
 
 - put the configuration parameters into isis.properites
 - get the parameter value in a domain service by
 container.getProperty(propertyName);
 
 Currently I get null value here...
 
 Thanks,Vladimir
 
 
 
 Here my code (relevant parts)
 
 
 @Named(Elasticsearch)
 @DomainService(menuOrder = 1.2)
 public class EsClient {
 
 private static final String ES_CLUSTER_PROPERTY_NAME =
 elasticsearch.cluster;
 private static final String ES_SERVER_PROPERTY_NAME =
 elasticsearch.server;
 private static final String ES_SERVER_PORT_PROPERTY_NAME =
 elasticsearch.port;
 ..
 ...
 
 @SuppressWarnings(resource)
   @PostConstruct
   @Programmatic
   public void connectToEs() {
 
   final String esClusterName =
 container.getProperty(ES_CLUSTER_PROPERTY_NAME);
   container.getUser()
   final String esServer =
 container.getProperty(ES_SERVER_PROPERTY_NAME);
   final String esPort =
 container.getProperty(ES_SERVER_PORT_PROPERTY_NAME);
 
   logger.info(Using elasticsearch properties from
 isis.poperties:
 +  server= + esServer + , +  port= + esPort + , +  cluster= +
 esClusterName);
 
   final Settings settings =
 ImmutableSettings.settingsBuilder().put(
 cluster.name, esClusterName)
   // .put(node.name, ES_LOCAL_NODE_NAME)
   .put(client.transport.nodes_sampler_interval, 10) //
 10
 //
 seconds
 //
 ping
   .put(client.transport.sniff, false).build();
   client = new TransportClient(settings).addTransportAddress(new
 InetSocketTransportAddress(esServer, Integer.valueOf(esPort)));
 
   logger.info(Connected to elasticsearch: +   server= +
 esServer + , +  port= + esPort + , +  cluster= +
 esClusterName);
 
   // instance a json mapper
   mapper = new ObjectMapper(); // create once, reuse
 
   }
 
   @PreDestroy
   @Programmatic
   public void disconnectFromES() {
   node.close();

ViewModel as return value of domain service

[Vladimir Nišević]

Hi everybody, here my second question today.

I need to provide a domain service which handles multiple elasticsearch and
database queries and builds a non persistent domain object and gives that
as a response to the 3rd party client thru REST API.

So my idea is to define a ViewModel classes representing my non-persistent
domain model and use them as method return value of a domain service. In a
domain service method I would make those elasticsearch and database queries
and then build and provide that object as a return value.

It seems that ViewModel cannot be returned thru REST API?

BR,Vladimir

Re: Adding data Nucleus to Eclipse

[Vladimir Nišević]

Hi, Eclipse has various perspectives. When developing Java, you usually use
one of this perspectives:  Java or Java EE. Perspective Java EE comes
with specific Eclipse plugins - J2EE Development - see
http://www.eclipse.org/downloads/moreinfo/jee.php

I've observed that Datanucleus plugin and  Add DataNucleus support
appears only in if the perspective Java but not Java EE. Maybe others
can confirm that, ff so, maybe somebody should update the instructions.

I'm using Juno on Windows 8.1 (all 64-bit versions) and have behaviour as
described...

 hik list

 I am trying to follow the instructions

 http://isis.apache.org/components/objectstores/jdo/datanucleus-and-eclipse.html

 to add Data Nucleus to my copy Eclipse Version: Luna Release
 Build id: 20131219-0014, the Data Nucleus plugin is list as version 3.04.

 I do not see any of the 'Add DataNucleus support', on the dom project
 eclipse  properties menu, but it is listed when you click properties.

 On the same page, there is a section off code to add to a pom file, under
 the title 'Update the classpath', there is no version supplied which
 causes maven to barf when it see new dependency

 The platform is Windoz 7

 AM  I suffering from a version issues or is this case of out dated
 documentation?

 Dave.
