Re: [Dev] [DSS][AXIS2][AXIS2-JSON] Writing a new XML to JSON conversion
@Ragith I checked out whole patch0007, couldn't build from the root(created
some dependency problems with "dependencies/orbit/axis2-json" module...
some relative path dependency pom files... i'm working on it nw ). So build
only "dependencies/axis2/modules/json" module, copy the generated jar to
the folder called 'patch0008'
under wso2dss-3.2.1/repository/components/patches Not "dependencies/orbit/
axis2-json".
@Shameera Thanks for asking that, problem is DSS json response is not
uniform, so not convenient for the consumer. As an example, for a given
select-query-operation there can be 3 types of responses.
1) There are no records.
{"Entries";""}
2) Only one record.
{"Entries":{"Entry":{"col1":"val1","col2":"val2"}}}
3) More than one records.
{"Entries":{"Entry":[{"col1":"val1","col2":"val2"},
{"col1":"val3","col2":"val4"}]}}
When consuming the service there are few validation checks we have to do.
No1 is partially OK, simple null check. But in No2 & No3, when we are
getting the value of key "Entry" we have to check whether is it an array of
objects or just an object, which i think is not convenient for the
consumer.
So I want to come up with a uniform type of response as below.
1) {"Entries":{"Entry":[]}}
2) {"Entries":{"Entry":[{"col1":"val1","col2":"val2"}]}}
3) {"Entries":{"Entry":[{"col1":"val1","col2":"val2"},
{"col1":"val3","col2":"val4"}]}}
Any thoughts?

Re: [Dev] [DSS][AXIS2][AXIS2-JSON] Writing a new XML to JSON conversion
Hi,
I have tried with putting a jar file as a library to the
repository/conf/lib folder. But it throws an exception when initializing
axis2.xml file with class not found exception. Maybe axis2.xml get loaded
before loading the classes in lib folder. Below is the exception which was
thrown.

Hi Rajith, Why are you asking him to build the patches , can't he work on already released DSs pack, Here i am trying to understand which issue Yasas trying to address by implementing a new JSON builder and formatter, we have plenty of Builders and formatters for JSON :) .

Hi Yasas, Try out creating a simple jar and put it in lib folder as shameera mentioned in above reply. I have tried out the scenario I have explained to you, and it worked fine for me As I mentioned, have you build the whole patch from the pom.xml inside patch0007 folder? and have you created "patch0008" folder and copied the jar(axis2-json-1.6.1-wso2v10.jar) inside "patch0007/dependencies/orbit/axis2-json/target" folder to the "patch0008" folder?

Hi Yasas, For you ClassNotFoundException, check do your axis2-json jar has required classes, BTW as i mentioned in previous reply you don't need to do any code changes to axis2 jars in order to plug your custom builders.

Re: [Dev] [DSS][AXIS2][AXIS2-JSON] Writing a new XML to JSON conversion
Hi Yasas, Assuming you are going to customize the JSON mapped convention (Standard Mapped Json support is their with Axis2),You don't need to do anything to axis2 jar. Implement your new JSON builder and formatter, then create a new jar(or osgi bundle) using those new classes and copy that jar ( or osgi bundle) to /repository/components/lib ( or /repository/components/dropings) directory. Finally, you need to configure your builder and formatter in axis2.xm configuration file (like your 3rd step). Thanks, Shameera.

Re: [Dev] [DSS][AXIS2][AXIS2-JSON] Writing a new XML to JSON conversion
Hi Yasas, The points you have mentioned are correct, but there are small changes I would like to point out. Below are the steps you'll need to follow to achieve your goal. 1 - There is a patch release for the "axis2-json" so you'll need to check out the source from [1] instead of the svn location you have mentioned. (checkout the whole "patch0007" instead of json module, so that it'll be easy for you to build the source.) 2 - Add the classes you need to the source. You'll need to extend AbstractJSONMessageFormatter in your custom formatter class You'll need to extend AbstractJSONOMBuilder in you custom builder class 3 - Build the whole patch0007. Then go to "patch0007/dependencies/orbit/axis2-json/target" folder where you can find the osgi bundle created from "axis2-json" module. 4 - Create "patch0008" folder inside "DSS_HOME/repository/components/patches" folder and copy the osgi bundle you found in step 3 to that folder. 5 - Add "messageFormatter" and "messageBuilder" elements to the "DSS_HOME/repository/conf/axis2/axis2.xml" as you have pointed out in your step 3. 6 - Restart the server and invoke your service adding "Accept" request header to the request with new content type you mentioned in "axis2.xml", example would be "Accept:application/json/newformat".(You can find sample of how to do it in [2]) [1] - https://svn.wso2.org/repos/wso2/carbon/kernel/branches/4.2.0/patches/patch0007/dependencies/axis2/modules/json/ [2] - http://janakaranabahu.blogspot.com/2013/06/return-json-response-from-wso2-dss.html Thanks, On Sun, Jul 13, 2014 at 1:45 PM, Yasas Karunarathna wrote: > Hi there, > > I want to do a small change to the json response returned from DSS 3.2.1. > I'm using JSONMessageFormatter & JSONOMBuilder in org.apache.axis2.json > package.(not gson implementations) > My requirements are as follows > > 1) Implement new JSONMessageFormatter, JSONOMBuilder etc. > And additional method accepting the Mapped json response and format it > accordingly, call it at the end of mapped json conversion. > 2) Build axis2-json-1.6.1-wso2v10.jar adding new classes. > I think this is the source used in DSS 3.2.1 : > https://svn.wso2.org/repos/wso2/carbon/kernel/branches/4.2.0/dependencies/axis2/1.6.1-wso2v10/modules/json > > 3) State new Formatter and Builder in axis2.xml & call it with new header > > class="org.apache.axis2.json.newJSONMessageFormatter"/> > > class="org.apache.axis2.json.newJSONOMBuilder"/> > Can anybody advice me on achieving the above requirements? > > -- > > Thanks > > > > *Yasas Karunarathna* > yasasblog.wordpress.com > > ___ > Dev mailing list > Dev@wso2.org > http://wso2.org/cgi-bin/mailman/listinfo/dev > > -- Rajith Vitharana Software Engineer, WSO2 Inc. : wso2.com Mobile : +94715883223 Blog : http://lankavitharana.blogspot.com/ ___ Dev mailing list Dev@wso2.org http://wso2.org/cgi-bin/mailman/listinfo/dev
