Interview Questions.

Question 1. How To Run Multiple Hybris Instance In One Machine?

Answer :

Basically hybrid runs on a tomcat instance. Hybris is distributed with a bundled tomcat. So the question here is absolutely, a way to run multiple tomcat in a single gadget.

We can run as many hybris we need, till our gadget reminiscence lets in. To achieve this, we want to make each instance of tomcat to have it’s own ports to use. Make underneath ports precise for every instance. We should add below homes in local property record of each example with unique values..

Tomcat.Http.Port=7001

tomcat.Ssl.Port=7002

tomcat.Ajp.Port=7009

tomcat.Jmx.Port=7003

tomcat.Jmx.Server.Port=7004

Question 2. Why Order Is Important In Items.Xml?

Answer :

We need to comply with an order in gadgets.Xml, while we declare object types in objects.Xml. Below are the motives for it.

Each items.Xml is parsed in single bypass. This method, more specific types are depending on widespread types. In such case they should were defined earlier than we use them. For example,

Here we see that, item kind product is the use of other object kinds, like catalog. To make this record efficiently, it's miles mandatory that catalog exist earlier than product is asserted. We ought to defines kinds in order of inheritance.

NOTE: Impex documents are parsed in more than one pass, so order is not crucial there.

Each xml record is confirmed in opposition to a gadgets.Xsd at some point of build. If the xml file does not conforms to xsd report, construct will fail.

Question three. What Is Role Of Jalosession?

Answer :

The Jalo layer in hybris is depreacted, no longer the jalosession.

Whenever a request is made to hybris server, it may need current consumer information, foreign money, language, timezone and many others to serve that request successfully. Since HttpSession does not keep all these information, hybris got here up with the idea of JaloSession.

Whenever a request involves Hybris, the filter HybrisInitFilter creates an object of JaloSession. Every JaloSession item is associated with a SessionContext object, which has present day consumer, language, currency and so on and the modern-day httpSession item.

Cron jobs additionally run in a JaloSession.
Each JaloSession is bound to a tenant. This can not be modified, after the example of JaloSession is created.
JaloSession is by no means made chronic in database.
Question four. What Are Model Attributes?

Answer :

Some time it's miles important to get few information in many JSPs, and we don’t want to skip them as part of DTO (facts objects). For example, the titles (Mr and Mrs and so on). They can be used in lots of JSPs and tags record, like registration, transport address and many others.

In such cases, what we do is, create a handy approach in Abstract controllers, and use version attribute annotation for them. In this manner they are available from all JSPs directly  using version attribute.

These can be accessed immediately in JSPs or even tag files. Like

Current Language : $cutting-edge Language

Model service create technique vs new operator

When we try to create a brand new instances of an object kind programmatically, we've got  options, the use of the java manner, the usage of new operator or the hybris manner, the use of the version provider.

ProductModel product1 = new ProductModel();

ProductModel product2 = modelService.Create(ProductModel.Magnificence);

The advantages of the usage of model carrier approach are beneath:

The version service create technique will generate and assign the pk for product item.
The create approach will initialize the default values, described in items.Xml for mandatory attributes.
While calling keep all approach, the item is already attached to context, and can be saved. While product1 wishes to attach explicitly.
So we should continually go for version provider manner in hybris.

Question five. Why Models Are Generated In Platform Extensions?

Answer :

Hybris is build over the principles of extensions. Each extension has it’s personal information model. Any extension can use an object type from other extension and increase it as in line with requirement.

For example, the itemtype  product defined in middle extension. The catalog extension has extended the product itemtype, and brought supplier to it.

While building the hybris, the frameworks builds according to dependencies. Since middle is construct earlier than catalog extension, it isn't always privy to the vendor attribute defined in catalog extension. If we preserve version class in extensions, then there'll e danger of build screw ups. Like in our case, seller characteristic will no longer discover a place in Product Model magnificence.

Hybris build framework, creates model instructions, even before, constructing any extension. The platform is the nice area to hold them, as each extension is constructed upon it most effective. So it isn't logical to create model lessons in particular extensions, whilst we can outline same records version in diverse extension.

Question 6. How To Split An Order Into Multiple Consignment?

Answer :

While pleasant an order, a while it's far vital for enterprise to split the order into multiple orders.

For instance, a purchaser orders  items A and B, now A has delivery window of 2 days, at the same time as B can be delivered in minimum 5 days. Now enterprise has the choice to both deliver each gadgets in 5 days. But what if item A is fresh, and could get destroyed in 5 days. There can be a case, where consumer wishes a obligatory shipping of object A inside 2 days. In such conditions, if commercial enterprise residence doesn’t need to free patron, it has no preference however to split order and ship it a couple of times. This is the case of break up consignment.

Now there may be diverse situations, which might also name for splitting the order into a couple of consignments. Above instance is just one in every of them. For example, we might also need to break up consignment, based on warehouse from where item might be picked up. We can also want to cut up consignment, based totally on product type (clean or ambient) and so on. These conditions which makes a decision the commercial enterprise logic to be a case for splitting the consignments, are called splitting strategies. We can have as many as approach to cut up, as we want.

By default, hybris creates only one consignment for an order. This is carried out with the aid of following carrier.

As you may see, that the order Splitting Service accepts a list of strategies, we can create many techniques, and split our order. The real commercial enterprise good judgment for splitting will go into strategy class.

Question 7. How To Setup A Svn Environment For Hybris Projects?

Answer :

Maintaining a version gadget for any task is one of the most critical aspect. Hybris initiatives aren't unique in this regard. They additionally do have the same lifestyles cycle in phrases of improvement. We want to keep specific environments like SIT, UAT and so forth. To provide a neighborhood development surroundings is likewise similarly crucial.

Since the size of OOB Hybris is huge, it's miles difficult to put the whole thing in SVN (or GIT). Also it is not beneficial. The hybris is improvising every day. A new release ought to now not give us ache in phrases of development.

The great practice for versioning a hybris assignment will be:

Put most effective custom folder, containing customized extensions to versioning software.
Pass brand new neighborhood.Residences, neighborhood extensions locally to every developers.
Maintain copy of new local.Residences, nearby extensions in each of servers like development and SIT, UAT and so forth.
Hybris software program is wrapped round custom folder on each surroundings.
Media folder could probably in SVN or can be passed regionally like belongings documents.
Production environment, generally isn't always related to SVN. Rather we take the most strong copy from UAT and install it the use of some deployment tool like , bamboo.

<itemtype code=”MyItemType” autocreate=”false” generate=”false”>

        <custom-properties>

            <property name=”catalogItemType”><value>java.Lang.Boolean.TRUE</value></property>
