Help with JSON to POJO using XML Routes
I'm using Camel - through ServiceMix - to retrieve data from a web service,
read the response and pass the data to another application. This code was
inherited, so much of the framework already exists. it used to read from a
database, but now needs to get its input from the web service response.
Problem is, I can't figure out how to read the data into the bean and all my
log statements within the java code get ignored. This makes debugging
difficult. I was hoping someone with more experience could shed some light
on my situation. For those paying attention, I did post on the ServiceMix
board, but that was a different question in the same route.
Questions:
1) How do I reference a set of java classes to unmarshal the message
using the Jackson API?
2) How do I enable logging within the java bean?
3)These messages are quite large. How do I stream data into the
Exchange/POJO?
Here are my routes:

If you put a log message right after the Netty call what does it show?

Re: Help with JSON to POJO using XML Routes
Posted by jeffz <jz...@hotmail.com>.
Thanks Ranx,
I was able to address logging by modifying the config file (it was set to
WARN). Now, my next step is to actually read the JSON. Since I can't read
it directly into POJO, I'm left using the generic unmarshal and reading the
data as a map. Is that something you can help with? My java method and
JSON are below. If I can learn how to iterate this thing, it definitely
helps. Also, any tips for processing large JSON are much appreciated. My
experiments with streaming have not gone well.
public void loadRetailStoreDataFromMap(Exchange input, Registry
paramRegistry) throws Exception {
final String METHODNAME = "loadRetailStoreDataFromMap()";
LOGGER.warn(METHODNAME + " loading data from Map: ");
Map body = (Map)input.getIn().getBody();
String strData = "";
strData = (String) body.get("recordSetTotal"); <-- RETURNS
NULL
LOGGER.warn(METHODNAME + "Data " + body);
// First load data into DB table
List<RetailStorePOJO> storeData = loadStoreDataFromMessage(body);
if(null != storeData && storeData.size() > 0) {
//System.out.println("Before calling buildSPRetailStoreDataXML()...");
List<String> retailStoresXMLStrList =
buildSPRetailStoreDataXML(storeData);
//System.out.println("After calling buildSPRetailStoreDataXML()...");
//System.out.println("Before calling loadSegmentDataIntoSP()...");
for(int i = 0; i < retailStoresXMLStrList.size(); i++) {
String retailStoresXML = retailStoresXMLStrList.get(i);
loadRetailDataIntoSP(retailStoresXML, paramRegistry);
}
//System.out.println("After calling loadRetailDataIntoSP()...");
}
LOGGER.debug(METHODNAME + " exit: ");

By the way, I think I used to use:

I'm going to assume that the method named there is on the bean. The log
messages may be getting ignored due to the logger not being set up
correctly. You can temporarily replace with System.out until you have time
to go back and make sure the logger is setup up correctly. As for the
loading of the bean, try instead of:
<to uri="bean:StoreLoadBean?method=loadRetailStoreDataFromMap"/>
<to uri="StoreLoadBean?method=loadRetailStoreDataFromMap"/>
You could also try:
<method ref="StoreLoadBean" method="loadRetailStoreDataFromMap"/>
You may not even need to specify the method depending on what the data type
it is getting and if it matches only one method on your bean.
I've switched lately from using blueprint XML to the Java DSL so trying to
dredge that up in my memory is a little difficult.

Re: Help with JSON to POJO using XML Routes
Posted by jeffz <jz...@hotmail.com>.
Hi Ranx,
You are correct that I need to get call a web service, get the response,
transform it, and send it to another system. The integration gets
information about stores and forwards it to a marketing system. We are
making the change because the database is going away.
Old: AutoStart -> Query database for store info -> Format & Send
New: AutoStart -> Hit URL for store info -> Format & Send
My route replaces autostart with a queue so that I can test. I built two
routes (one to call the service, the other to format), because I kept
getting stream closed when trying to unmarshal the web service response.
When I hit the http4{url}, I am getting back a JSON string as a result; so
that part is working.
if I use the below defined "jack" bean, it will unmarshal the message and
appears to invoke the java bean. I say appears because all of my log
statements inside the java method are ignored.
If I use the "tst" bean, pointing to my java POJO, the route won't even
start. There, I get: Caused by: java.lang.IllegalArgumentException: Cannot
find data format in registry with ref: tst
Here is my trace from the jack invocation
8 >>> (route665) bean://LoadBean?method=loadRetailStoreDataFromMap -->

Re: Help with JSON to POJO using XML Routes

I didn't see in your initial code anything that set up the dataFormat.
That along with the unmarsal/marshal are what you need to get it to work
correctly, not just using a bean.
<dataFormats>
<json id="jack" library="Jackson" unmarshalTypeName="com.example.
RetailStoreReturnPOJO""/>
</dataFormats>
Then in your route, right after your call* to* http4 you put:
<unmarshal ref="jack"/>

Jackson works fine and I've used it many times. So does JAXB for JSON.
Just remember to put the @XmlRootElement annotation on your bean in that
case (yeah, even it if is only being used for JSON). I really wouldn't fool
with the gapping of strings to a hashmap. You'll just create headaches. You
can also use XStream with jettison. XStream is one of my favorite
libraries though I don't usually use it to marshal/unmarshal JSON.
Right after your call to http4 log the return data and post it. One item
I've seen in the past in the context of web service calls is that it will
put the individual elements it gets back in an array and you have to fish
the zeroeth element out of the array to get the actual item you're looking
for.
But if you just print out/log what you get right after the call TO http
that should help.

Re: Help with JSON to POJO using XML Routes
Posted by jeffz <jz...@hotmail.com>.
That's actually how it originally was, but I changed it while working on my
older 'stream closed' issue. I can switch that back. I'm actually pretty
close now, just running into some issues reading certain fields within the
map object.

As Ranx mentioned, shouldn't the http4 component be a producer rather than a
consumer? (to rather than from?)
i.e. <*to * uri="http4://{{url}}"/>

Incidentally, this is where a bit of my confusion lies:
to retrieve data from a web service,
read the response and pass the data to another application. (make a
request and get the response?) <*to *uri="http4://{{url}}"/>
it used to read from a database, but now needs *to get its input from the
web service response*. (I take it you don't mean receiving input but making
a request and getting the response? That is calling to the http4 client to
some other server that is sending back a response?)
From what I see that seems to be what you want since you are sending
something over activemq and your route is receiving it (from) but that is
followed by another (from) which would sit and wait for someone to call
it. That doesn't really do much with the incoming activemq message then.

By the way, which version of Camel are you using? And maybe I'm not quite
understanding what you're trying to do but it sound like you want to call *to
*an http endpoint and aren't waiting to receive from the endpoint.
