Remove a document from Mongo DB with Apache Camel

My main issue might be not understanding some conventions in the Camel documents.
https://camel.apache.org/components/latest/mongodb-component.html#_delete_operations
They have a camel route commented out, and two Java objects being defined, which are not commented out. What are they trying to indicate? Where are these objects at in a project?
Anyway, I'm subscribed to a JMS queue that I have another camel route publishing to. The message is a JSON string, which I save to a Mongo DB. But what I'd like to do is remove any current documents (based on criteria) and replace it with the new message.
from("jms:topic:orderbook.raw.feed")
.log("JMS Message: ${body}")
.choice()
.when().jsonpath("$.[?(#.type=='partial')]")
// Figure out how to delete the old orderbook from Mongo with a type=T1
.to("mongodb:mongo?database=k2_dev&collection=orderbooks&operation=save");

Does your orderbook have an ID? If so, you can enrich the JSON with an _id field (MongoDB default representation for identifiers) whose value would be that ID. Thus you'll be "upserting" that orderbook.
Obs.: Sure the Camel docs could be better.
But if you really feel you'd have to perform a remove operation before saving an orderbook, another option would be to extract its type from the current JSON string and use it as a filter when removing. Something like:
from("jms:topic:orderbook.raw.feed")
.log("JMS Message: ${body}")
.filter("$.[?(#.type=='partial')]")
.multicast().stopOnException()
.to("direct://orderbook-removal")
.to("direct://orderbook-save")
.end()
;
from("direct://orderbook-removal")
// extract type and set it as the body message. e.g. {"type":"T1"}
.to("mongodb:mongo?database=k2_dev&collection=orderbooks&operation=remove")
;
from("direct://orderbook-save")
.to("mongodb:mongo?database=k2_dev&collection=orderbooks&operation=save")
;
The multicast sends a copy of the message to each destination. So the content won't be affected.

Getting an error code 80 on textlocal

I am using TextLocal tool to send SMS in my java code. I am using the same code snippet given here.
This is a transactional account. I am getting the following error
{"errors":[{"code":80,"message":"Invalid template"}],"status":"failure"}
This error code is nowhere found in the TextLocal documentation. Please let me know the solution if anyone has faced this issue before.

This was happening because the TextLocal transactional messages should be given a message template through the TextLocal dashboard and all the SMS sent should follow all the rules of these messages.
After the template has been created and followed, the issue is resolved.

go to Your login dashboard of textlocal
Then in send menu go to template and draft.
then open your template to see the message format.
And provide same massage format to your java method to send message.
Hope may it help you.

Few quick points to check
1.Is the message that you are passing in your API as per your approved
templates? If not, this error will come in response to your API. You
can check your approved templates under Send -> Templates & Drafts
2.Are all special characters in your template (&, #, #...) URL
encoded?
3.Are you using the same placeholder name
for multiple dynamic/replaceable parameters in your API? They have
to be unique.
4.Are you exceeding the max character length set for
the placeholder? Are you using a newline character? Replace all the
newline characters with %n
The above points are from textlocal SMS API documentation. You can also try copying the content of approved textlocal template into the Java code.

This because of the sending message content doesn't match the template which you created on the textlocal account.
check template is created or not. If not create a template and try.
If created check current message content match with your existing template.

This is happening because,
From a transactional account you can send only those messages that
match one of your pre-approved templates. Please ensure that your
messages match one of the approved template formats.
To create a Template,
Go to Your login dashboard of textlocal-> Send -> Templates and Drafts.
Then create a Template. Templates can be 2 types Static & Dynamic. You can create both by using this. Template message format should match the format in your code.
I am providing a link.. This will help to understand this more clearly.
How to create and format template

How to call routes in a controller java play?

I'm writing an app with Java play OAuth2. When I was went through on a sample code(code), It has a line,
String url = routes.Twitter.auth().absoluteURL(request());
Twitter is a class and solve the compile error issue on this line. How may I call the routes like this in a controller?

That's reverse routing and syntax is valid, so if you have compile error at this point that means that you probably didn't add valid route declaration for your action within the /conf/routes file

Creating a filter to check a case for a letter in a field in the json body in REST assured

I have a request in the form of json,which looks like this.
{"User":{"email":"test#test.com","FName":"fname"}}
When I try to send it via REST assured ,the U in the User is seen to change its case.i.e. changes to a lower case.
To send the request I have created my own serialized classes. The end-point is seen like this:
{"user":{"email":"test#test.com","FName":"fname"}}
but somehow it is not changing the case of the remaining fields.I don't knwo why this is happening.
I've even tried to create a filter for a request specification,but couldn't go any further with that too. I also then thought of first converting the serialized object to a gson,and then check the case of the User, still no luck.
Error I get is:
The class, User,does not match the payload object for payload.
Please note I am trying to use the service of another team,so I really don't have an access to their code-base(Although not needed).Observe the space between the first , and user in the above message, is it worth noting?

I finally got away with it by converting the object(JSON) into a JSON string/payload.
And while passing it as a form parameter,passed the string/payload.
Somehow,still couldn't figure out why the formparameter/formparam option in RESTAssured did not allow the serialized object to go through. But,anyway got around it this time.
Thanks for the suggestions all.

Sending custom object as a parameter for a web-service

How can one specify a custom object as a parameter for the web-service's method when invoking through SOAP message?
Say I have this code:
SOAPElement operation = body.addChildElement("MyMethod", "", trgNamespace);
SOAPElement value = operation.addChildElement("arg0");
value.addTextNode("i need to send here a custom object not a string")
request.saveChanges();
The addTextNode sends a string whereas I need to send my own object as a parameter for invocation.

You have to serialize your object to transfer it over the line. Serialization is often done using XML or JSON, see the following link for details: http://en.wikipedia.org/wiki/Serialization
That should get you on the right path.

Maybe try higher level and use wsdl-based stubs generator for java? It's Axis wsdl to java

I could think of another approach
You can send that custom object as a binary data (I assume your object is serialize-able). Then encode that data in say Base64 encoding.
There is similar problem asked earlier. Plz check out this link. This seems most relevant to your problem.
Another link mentioned in the above posting gives nice overview of handling these type of problems in general.
