Unmarshaller failure - jaxb

I have to mrss feeds form which I'm getting the content via unmarshalling process. They look like to have the same structure, but in one case it is always returning null as 'mediaContent'. Can someone help what is the difference between the two feeds?
returns null:
http://smrss.neulion.com/u/nhl/mrss/sights-and-sounds/vod.xml
working correctly:
http://smrss.neulion.com/u/nhl/mrss/news/news_mrss.xml

At first glance seems that namespaces are different .. first one is http://search.yahoo.com/mrss, and the second is http://search.yahoo.com/mrss/. The second has a / at the end.

Passing data from one step to another using screenplay ( e.g. When -> Then )

Using serenity-js, with cucumber and screenplay, i can't get to pass data from one step to another. E.g. : a "When" step defined by a pretty user.attempsTo() that simply calls a webservice, and a "Then" step that should simply checks the response of the webservice. "TakeNote" forgets the data of the previous step ( as i could see, even surprising) and "LastResponse" context might be lost also...
I guess there is a simple way to store an object (as a Question maybe) in one Activity of the "When" step, and get back this object in an Activity of the "Then" step.
Without Serenity, i would use a World object that is clearly a simple way to do the job, but i'm sure there a Serenity pretty way to do the trick.
Thank you.

I tried to pass the object with LastResponse, with TakeNotes. But the object seems to be lost.
I found what was wrong (answering to myself).
user.attempsTo() is actually processed prior to the next step only if a resolution of the promise is asked, so if preceded by return, or await, or if it is declared as an implicit return using arrow function like this ( user :Actor) => attempsTo(...) ).
Without the promise resolution, interactions are not executed in the described sequence, and this is really no good.
The symptom for a bad code is that the interactions are not logged in their steps, but in step further. Hope this helps.

How to get a certain (e.g. second or third) mention sent in a message

I've been trying to make a ship command that can either ship the author of the message with a mentioned user, or ship two mentioned users. I can get the 1st mention in a message but I have no idea on how to get the 2nd or even third mention in a message. I tried using:
message.mentions.users.first(2)
splitting the args then slicing them so only the second mention is avalaible, but this gives an "undefined" error when I try to get the username.
Could someone give me a script on exactly how to do it since I can't really get the hang of this
According to the documentation message.mentions.users yields a Collection. So you can just iterate over this collection or convert it to an array and then access the required index:
const userArray = message.mentions.users.array();
console.log(userArray[yourDesiredIndex]);

AEM Query builder exclude a folder in search

I need to create a query where the params are like:
queryParams.put("path", "/content/myFolder");
queryParams.put("1_property", "myProperty");
queryParams.put("1_property.operation", "exists");
queryParams.put("p.limit", "-1");
But, I need to exclude a certain path inside this blanket folder , say: "/content/myFolder/wrongFolder" and search in all other folders (whose number keeps on varying)
Is there a way to do so ? I didn't find it exactly online.
I also tried the unequals operation as the parent path is being saved in a JCR property, but still no luck. I actually need unlike to avoid all occurrences of the path. But there is no such thing:
path=/main/path/to/search/in
group.1_property=cq:parentPath
group.1_property.operation=unequals
group.1_property.value=/path/to/be/avoided
group.2_property=myProperty
group.2_property.operation=exists
group.p.or=true
p.limit=-1
This is an old question but the reason you got more results later lies in the way in which you have constructed your query. The correct way to write a query like this would be something like:
path=/main/path/where
property=myProperty
property.operation=exists
property.value=true
group.p.or=true
group.p.not=true
group.1_path=/main/path/where/first/you/donot/want/to/search
group.2_path=/main/path/where/second/you/donot/want/to/search
p.limit=-1
A couple of notes: your group.p.or in your last comment would have applied to all of your groups because they weren't delineated by a group number. If you want an OR to be applied to a specific group (but not all groups), you would use:
path=/main/path/where
group.1_property=myProperty
group.1_property.operation=exists
group.1_property.value=true
2_group.p.or=true
2_group.p.not=true
2_group.3_path=/main/path/where/first/you/donot/want/to/search
2_group.4_path=/main/path/where/second/you/donot/want/to/search
Also, the numbers themselves don't matter - they don't have to be sequential, as long as property predicate numbers aren't reused, which will cause an exception to be thrown when the QB tries to parse it. But for readability and general convention, they're usually presented that way.
I presume that your example was just thrown together for this question, but obviously your "do not search" paths would have to be children of the main path you want to search or including them in the query would be superfluous, the query would not be searching them anyway otherwise.
AEM Query Builder Documentation for 6.3
Hope this helps someone in the future.
Using QueryBuilder you can execute:
map.put("group.p.not",true)
map.put("group.1_path","/first/path/where/you/donot/want/to/search")
map.put("group.2_path","/second/path/where/you/donot/want/to/search")
Also I've checked PredicateGroup's class API and they provide a setNegated method. I've never used it myself, but I think you can negate a group and combine it into a common predicate with the path you are searching on like:
final PredicateGroup doNotSearchGroup = new PredicateGroup();
doNotSearchGroup.setNegated(true);
doNotSearchGroup.add(new Predicate("path").set("path", "/path/where/you/donot/want/to/search"));
final PredicateGroup combinedPredicate = new PredicateGroup();
combinedPredicate.add(new Predicate("path").set("path", "/path/where/you/want/to/search"));
combinedPredicate.add(doNotSearchGroup);
final Query query = queryBuilder.createQuery(combinedPredicate);
Here is the query to specify operator on given specific group id.
path=/content/course/
type=cq:Page
p.limit=-1
1_property=jcr:content/event
group.1_group.1_group.daterange.lowerBound=2019-12-26T13:39:19.358Z
group.1_group.1_group.daterange.property=jcr:content/xyz
group.1_group.2_group.daterange.upperBound=2019-12-26T13:39:19.358Z
group.1_group.2_group.daterange.property=jcr:content/abc
group.1_group.3_group.relativedaterange.property=jcr:content/courseStartDate
group.1_group.3_group.relativedaterange.lowerBound=0
group.1_group.2_group.p.not=true
group.1_group.1_group.p.not=true

Best practice to pass query conditions in ajax request

I'm writing a REST api in node js that will execute a sql query and send the results;
in the request I need to send the WHERE conditions; ex:
GET 127.0.0.1:5007/users //gets the list of users
GET 127.0.0.1:5007/users
id = 1 //gets the user with id 1
Right now the conditions are passed from the client to the rest api in the request's headers.
In the API I'm using sequelize, an ORM that needs to receive WHERE conditions in a particular form (an object); ex: having the condition:
(x=1 AND (y=2 OR z=3)) OR (x=3 AND y=1)
this needs to be formatted as a nested object:
-- x=1
-- AND -| -- y=2
| -- OR ----|
| -- z=3
-- OR -|
|
| -- x=3
-- AND -|
-- y=1
so the object would be:
Sequelize.or (
Sequelize.and (
{x=1},
Sequelize.or(
{y=2},
{z=3}
)
),
Sequelize.and (
{x=3},
{y=1}
)
)
Now I'm trying to pass a simple string (like "(x=1 AND (y=2 OR z=3)) OR (x=3 AND y=1)"), but then I will need a function on the server that can convert the string in the needed object (this method in my opinion has the advantage that the developer writing the client, can pass the where conditions in a simple way, like using sql, and this method is also indipendent from the used ORM, with no need to change the client if we need to change the server or use a different ORM);
The function to read and convert the conditions' string into an object is giving me headache (I'm trying to write one without success, so if you have some examples about how to do something like this...)
What I would like to get is a route capable of executing almost any kind of sql query and give the results:
now I have a different route for everything:
127.0.0.1:5007/users //to get all users
127.0.0.1:5007/users/1 //to get a single user
127.0.0.1:5007/lastusers //to get user registered in the last month
and so on for the other tables i need to query (one route for every kind of request I need in the client);
instead I would like to have only one route, something like:
127.0.0.1:5007/request
(when calling this route I will pass the table name and the conditions' string)
Do you think this solution would be a good solution or you generally use other ways to handle this kind of things?
Do you have any idea on how to write a function to convert the conditions' string into the desired object?
Any suggestion would be appreciated ;)
I would strongly advise you not to expose any part of your database model to your clients. Doing so means you can't change anything you expose without the risk of breaking the clients. One suggestion as far as what you've supplied is that you can and should use query parameters to cut down on the number of endpoints you've got.
GET /users //to get all users
GET /users?registeredInPastDays=30 //to get user registered in the last month
GET /users/1 //to get a single user
Obviously "registeredInPastDays" should be renamed to something less clumsy .. it's just an example.
As far as the conditions string, there ought to be plenty of parsers available online. The grammar looks very straightforward.
IMHO the main disadvantage of your solution is that you are creating just another API for quering data. Why create sthm from scratch if it is already created? You should use existing mature query API and focus on your business logic rather then inventing sthm new.
For example, you can take query syntax from Odata. Many people have been developing that standard for a long time. They have already considered different use cases and obstacles for query API.
Resources are located with a URI. You can use or mix three ways to address them:
Hierarchically with a sequence of path segments:
/users/john/posts/4711
Non hierarchically with query parameters:
/users/john/posts?minVotes=10&minViews=1000&tags=java
With matrix parameters which affect only one path segment:
/users;country=ukraine/posts
This is normally sufficient enough but it has limitations like the maximum length. In your case a problem is that you can't easily describe and and or conjunctions with query parameters. But you can use a custom or standard query syntax. For instance if you want to find all cars or vehicles from Ford except the Capri with a price between $10000 and $20000 Google uses the search parameter
q=cars+OR+vehicles+%22ford%22+-capri+%2410000..%2420000
(the %22 is a escaped ", the %24 a escaped $).
If this does not work for your case and you want to pass data outside of the URI the format is just a matter of your taste. Adding a custom header like X-Filter may be a valid approach. I would tend to use a POST. Although you just want to query data this is still RESTful if you treat your request as the creation of a search result resource:
POST /search HTTP/1.1
your query-data
Your server should return the newly created resource in the Location header:
HTTP/1.1 201 Created
Location: /search/3
The result can still be cached and you can bookmark it or send the link. The downside is that you need an additional POST.

BizTalk: Getting error in Promoted Property

I am getting below error when I run the Orchestration and try to assign value to a promoted property by reading the value of another promoted property.
Error in Suspended Orchestration:
Inner exception: There is no value associated with the property BankProcesses.Schemas.Internal_ID' in the message.
Detail:
I have 2 XSD schemas, 1 for calling a stored procedure and reading its response and another to write it into a flat file. The internal ID returned in the response from SP needs to be passed to a node in another XSD schema to write to a flat file format.
I have promoted an element from the response schema and also promoted an element from the schema to write to flat file. I am assigning the value to promoted propeties as below:
strInternalId = msgCallHeaderSP_Response(BankProcesses.Schemas.Internal_ID);
msgCallSP(BankProcesses.Schemas.Header_Internal_ID) = strInternalId;
But when I run the orchestration I get the error as mentioned above. I have checked the reponse from stored procedure and the reponse XML does contain some value but I am unable to assign that value to another schema. Please advice
Thanks,
Mayur
You can use exists to check the existence of property.
if(BankProcesses.Schemas.Internal_ID exists msgCallHeaderSP_Response)
{
strInternalId = msgCallHeaderSP_Response(BankProcesses.Schemas.Internal_ID);
msgCallSP(BankProcesses.Schemas.Header_Internal_ID) = strInternalId;
}
One scenario that might cause this error is that there is no Header_Internal_ID element in the message you are trying to modify. Can you inspect the message before modification to ensure that there is an element whose value should be changed - drop the message out to a file location, maybe.
If this is the case, then just ensure that you create this element when you instantiate you r message for the first time - even if you initially set it to an empty element.
HTH
To check if the property exists, you can use this syntax:
BMWFS.LS.BizTalk.CFS.BankProcesses.Schemas.Internal_ID exists msgCallHeaderSP_Response
However, if the case is that the source field would always be there, you have to work backwards to find out why the Property is not appearing on the Context.
If it's coming from a Port, is the message passign through an XmlDisassembler Component? If it's coming from another Orchestration, are you actually setting the Property?
The easiest way to look at the Context is to route the Message, msgCallHeaderSP_Response, to a Stopped Send Port. You can then view the Context in BizTalk Administrator.
