[Dev] [WSO2-EI] ESB Analytics conflicts with WSO2AM analytics
Hi In a profile where client have ESB and APIM analytics in separated instances, but sharing governance registry space, ESB analytics try to run tasks of WSO2AM analytics and that causes errors in ESB analytics, for example the registry: /_system/governance/repository/components/org.wso2.carbon.tasks/definitions/-1234/ANALYTICS_SPARK/APIMAnalytics-AbnormalTierUsageAlert-AbnormalTierAvailabilityAlert-batch1 I know that we can solve this changing registryRoot on both servers, but in this case the client wish to have governance registry shared between all servers that is the purpose of governance registry space. Anyway to configure ESB analytics and APIM Analytics without these conflicts? Best regards Clóvis ___ Dev mailing list Dev@wso2.org http://wso2.org/cgi-bin/mailman/listinfo/dev
[Dev] [WSO2-EI] doubt about analytics identity.xml and integration with WSO2-IS
Hi, Reviewing the puppet modules for pattern 6 of EI, I see that both analytics1 and 2 points to wso2_carbon_db, that is for local registry space for each instance, is that correct? or better is to have a central wso2idn database, for future shared use with WOS2IS? best regards.

[Dev] [WSO2IS] use of sessionDataKey and user bookmarking the login page
Hi The problem is about the user bookmarking login page that have sessionDataKey on the URL, somedays after that session got invalid and the bookmark always got invalid session until user click to redirect for correct page. I'm try to figure ways to deal with authentication framework specifically on the customization of login.do and know better about sessionDataKey, but I cant find any idea, for example how to check if sessionDataKey is valid, and if not, send back to authorization that give back a new sessionDataKey. Can someone explain the idea behind sessionDataKey or anyone have the correct way to solve user using browser to bookmarking login page, but the correct is to bookmarking the redirect_uri?

Hi Lakshman,
I reviewed and can build better with version tag 3.1.7 of the agent, the
problem before was about SSLv3 disabled on server, then on agent I forced
to use a lower version. Now I can do enrollment, but cant get the

to be a problem at server side now on

Hi Clovis,
According to the compatibility doc [1], IOT 3.0.0 should work with agent
2.0.0 version. Could you check the tag and build and see? Anyway, can you
see any error in log (server log or logcat)?

Hi, I'm try to configure and test with Sansung Tablet SM-T560 that uses Android Kitkat 4.4.4, when I try the application on emulator with same version all works fine, but when use with physical device dont get enrollment, I'm compiling the sources from git on branch release-2.0.0 (as I see that some changes in APIs dont worked with new branches) that work with version 3.0.0 of WSO2 IoTS.

[Dev] [DEV][AS] Ideas and ways to integrate with Hot Swap Agent
Hi, I'm researching for some ways to improve speed of development and redeploy on WSO2 Application Server, for example I have a scenario here where a simple change on a class, to test, get about 5 minutes. (as the test must pass by web interfaces in Jaggery, until reach the REST Api implemented in JAX-RS with Jersey and some JPA using EclipseLink. The Jaggery part is very easy, just rsync files, and all works fine. For the java part, in this research I found the HotSwapAgent - http://www.hotswapagent.org/ My first try was to follow HotSwapAgent quick start as is, and check if it works with WSO2 AS 5.2.1 out of the box, but dont worked, HotSwapAgent dont detect changes when I copy one updated .class file to WEB-INF/classes. Then my question is about, if anyone tried this before with WSO2, and if is a good way to invest time to implement a WSO2 plugin that work better with HotSwapAgent and what is the steps I must follow to implement this plugin or integrate this type of speed with redeploy with WSO2 AS? Maybe some problems with OSGi? ps: Note that the idea, is just change one class, rsync the binary .class file over respective WEB-INF/classes and got the results.

Re: [Dev] [DSS] start point for extending, creating plugins, new functions and resolving BUGs
Hi Anjana,
Just to leave a starting discussion about Data Services with RESTful from
the user view, I like this pattern:
http://www.eclipse.org/eclipselink/documentation/2.5/solutions/restful_jpa004.htm#CHDEGJIG,
and the idea to Pass by Reference to reduce the size of payload. What do
you think?
Best regards

Hi Clovis,
We are going to have some discussions and start on this early next year.
At the moment, it is holidays for us, starting back work on 5'th Jan. So,
stay tuned in the mailing lists in Jan, for the DSS 4.0 plans. I most
probably will be starting with a PoC with a possible new architecture for
DSS. And also, one of the items in the new design is to have proper
extension points to support new query types, data sources etc.. Native JSON
/ XML input/output adapters will be implemented by default.
Cheers,
Anjana.

Hi Clovis,
Yeah, at the moment, the REST support in data services is not ideal,
there are some technical limitations of Axis2 and how we handle the REST
requests and JSON handling and so on. But we are going to fix these with
our next major release of DSS, where we are going to re-architect how we
implement RESTful behavior and how to handle different data formats, so
after that, you will not have strict schema enforcements like
_postcountry in the JSON payload.
As for the NPE you're getting, can you please check on the latest 3.2.2
release, if you still get this error, since we have fixed several JSON
related bug in this release.
You can certainly check out the necessary source code from our SVN
repository (the current version is on our SVN at the moment, future
development is done on Github). For example, the latest data services core
component can be found here [1]. You can simply check it out, and build
using Maven, and it should download all the required dependencies from the
online repository. And you can do your fix, and build the jar and simply
replace that jar in the product's /repository/components/plugins directory,
to test it out (remember to replace the one in plugins directory, not just
copy the build jar to the directory). And of course, patches are always
welcome, simply create a JIRA for the product and attach it, and you can
also send a mail to the @dev list.
And lastly, do stay tuned for plans for DSS 4.0, these haven't been
finalized yet, we will start discussions on these soon.

I know how to do these things using JAX-RS, but I like to create this

For example, today in DSS we must send this payload to create a New
Country:
{
_postcountry:{
code:7,
name:BRASIL,
acronym:BRA,
bankCode:1058,

and this broke the RESTFul idea to use HTTP Methods, as some clients
use today the payload just as:
{
code:7,
name:BRASIL,
acronym:BRA,
bankCode:1058,
ddiCode:55
}
I know we can deal with this using mediation in ESB to inject the parts
needed by DSS, but why dont support this directly in DSS to avoid
unnecessary overheads? or for example, a more complex scenario, where I
post a payload with all data, and create the other data if necessary.
Other example, I wish to solve some bugs, like if we send this payload:
{
_postcountry:{
code:8,
name:BOLIVIA,
acronym:BOL,
bankCode: null,
ddiCode: null
