Re: [Dev] Why do we start C5 wso2servers by default in OSGI mode?

[Sajith Ariyarathna]

AFAIK, enabling OSGi console doesn't hurt runtime performance of the
product (at least in a significant way).
You can disable OSGi console via
/conf//osgi/launch.properties file. Set
osgi.console=none

Thanks.

Re: [Dev] SP Analytics REST APIs

Hi Bernard,

Analytics profile of EI-6.4.0 is an instance of SP-4.3.0. Please refer doc
[1] on the REST APIs exposed by SP.

Re: [Dev] [Architecture] Streamproccessor - report in excel format

[Sajith Ariyarathna]

Hi Jørgen,

Yes, currently dashboard only support "export as PDF". Unfortunately there
are no workaround to export to other formats (e.g. excel, csv), we have to
implement that. We don't have immediate plans to introduce new export
types. Based on a quick glance, I think we can do CSV but Excel will be
tricky. Please note that I have created issue [1] to track this.

Re: [Dev] Permission handling in SP

You can only give permissions (by setting roles) for dashboards only.
Currently we don't support permissions for widgets.

Re: [Dev] Using regex in Siddhi SQL queries

[Sajith Ariyarathna]

Can you share your Siddhi code block here?

I feel like what you have request here is similar to the functionality of
SQL IN operator, rather than a regex.

Also, have you tried to use the regexp function [1]?

Re: [Dev] [DEV][JAGGERY] Getting Empty JSON when logging(log.info)

[Sajith Ariyarathna]

Hi Manu,

 Point taken, logging circular objects is a problem. My concern is that,
logging Java objects details in "JSON string format" is not a good way to
do it. May be we can log details of the Java object without following the
JSON format. Like this,

(class: org.wso2.models.Student, toString: "name: Kamal, age: 25, city:
Colombo")


Thanks.

Re: [Dev] [DEV][JAGGERY] Getting Empty JSON when logging(log.info)

[Sajith Ariyarathna]

Hi Rajeenthini,

You are hoping to add the following code snippet to the serializeJSON
method [1] of the org.jaggeryjs.scriptengine.util.HostObjectUtil class.

> String JsonString = null;
> try{
> ObjectMapper mapper = new ObjectMapper();
> JsonString = mapper.writeValueAsString(obj);
> }catch (Exception e){
> System.out.println(e.getMessage());
> }
>
> return "{\"javaObject\":\"true\",\"object\":\"" + JsonString + "\"}";
>
> There are few issue in this code snippet.

   - Don't catch generic Exception, always catch a specific exception. In
   here you should catch JsonProcessingException [2].
   - Don't use System.out.println to log exceptions. Instead use a proper
   logger. HostObjectUtil class has a log object defined in line 30 [3],
   you can use that.
   - Returning '{"javaObject": "true", "object": "{ ... }"}' string gives a
   wrong impression that there are two attributes called 'javaObject' &
   'object' in the logged object. I think just returning the JSON string will
   be enough.

After corrections (I also took the liberty to reduce no of lines):

try {

return (new ObjectMapper()).writeValueAsString(obj);

} catch (JsonProcessingException e) {

log.debug("Object " + obj.toString() + " of class " + obj.getClassName() +
" cannot be converted to JSON");

}

return "{}";

Re: [Dev] [DEV][JAGGERY] Getting Empty JSON when logging(log.info)

[Sajith Ariyarathna]

Hi Rajeenthini,

AFAIK ability to convert a POJO into JSON object does nor affect the output
of a Jaggery Log of that POJO.
To get a proper log output for a Java object, you need to implement the
"toString" method in that Java class. For example in your case,

public class Student {

...

public String toString() {

return "{name: " + this.name + ", age: " + this.age + ", indexNo: " +
this.indexNo + "}";

}

}

Now you can log a Student object in your Jaggery code as following.

log.info(studentObj.toString());


Thanks.

Re: [Dev] Random errors from UUF

[Sajith Ariyarathna]

Hi Sumedha,

Seems like this is a concurrency problem. That's why the issue appears
randomly. According to this [1] email thread, issue is in the Handlebars
library (in UUF we use handlebars-v2.0.0.js library). Seems like
handlebars.js library is not thread-safe [2].

In UUF, a separate Handlebars environment is created from a shared root
Handlebars environment [3] for each HTTP request. Hence, the root
Handlebars environment is shared between threads (HTTP requests). However
the 'Handlebars.compile()' function is not thread-safe. That is the reason
behind  this issue.

I have fixed this problem by eliminating the shared root Handlebars
environment. See PR [4].

Re: [Dev] Governance Registry - Where to define a new handlebars helper ?

[Sajith Ariyarathna]

Hi Arnaud,

You can register custom Handlebars helpers in "theme.js" file. In your
case, it should be in
"/wso2greg-5.1.0/repository/deployment/server/jaggeryapps/publisher/themes/default/theme.js"
path. Refer [1] as an example.

[1]
https://github.com/wso2/carbon-appmgt/blob/80839ee805c72cc6b2c6d1a39f0ecfecbf81/features/org.wso2.carbon.appmgt.publisher.feature/src/main/resources/publisher/themes/mobileapp/theme.js#L6

[Dev] [IS] Possible bug in SPInitLogoutRequestProcessor class

[Sajith Ariyarathna]

Hi IS team,

When looking at the
"org.wso2.carbon.identity.sso.saml.processors.SPInitLogoutRequestProcessor"
class, I noticed that the same condition is checked twice in line 71 [1],
and line 79 [2]. According to the error message in line 80 [3], checked
if-condition in line 79 is incorrect.

Suggesting Fix: change the if-condition in line 79 to
StringUtils.isBlank(sessionIndex)

Re: [Dev] Issue in carbon logs after changing carbon.kernel.version from 4.4.1 to 4.4.2

[Sajith Ariyarathna]

Hi Malithi,

Seems that when you log.error(message, e); the stack trace does not get
sanitized, but if you do log.error(e); then the stack trace get sanitized.

Currently we are developing Jaggery app; when an exception occurred in
Jaggery code, Rhino engine logs the stack trace and that stack trace is
sanitized. Looks like our issue goes to Jaggery.

I also notices that in Jaggery, logging exceptions like log.error(e);
outputs a sanitized stack trace. One can avoid that by logging
exceptions log.error(message,
e); like this.

Hoping to discuss this with the Jaggery team. Thank you very much for your
assistance regarding this matter.

Re: [Dev] Issue in carbon logs after changing carbon.kernel.version from 4.4.1 to 4.4.2

[Sajith Ariyarathna]

Hi Malithi,

My concern is that current fix sanitizing stack traces even though stack
trace does not have CRLF injections in it. I believe sanitizing log
messages (e.g. log.error(message) , excaption.getMessage() ) is sufficient
to prevent  CRLF injections in logs.

I think we can overcome this problem with the my earlier proposed approach
(extending log4j PatternLayout class and overriding the format method).

Thanks.

[Sajith Ariyarathna]

Hi All,

Me and RasikaP dig a little deep to find a solution to this problem.

Instead of sanitizing final log message, you can sanitize when it is
formatted by extending the PatternLayout [1] class. Refer this code [2],
where public String format(LoggingEvent event) method is overridden to
achieve a custom log message formatting.  You can configure log4j
(log4j.xml) to use your extended Pattern Layout class by adding  in your  .

WDYT?

Re: [Dev] Issue in carbon logs after changing carbon.kernel.version from 4.4.1 to 4.4.2

[Sajith Ariyarathna]

Hi Malithi,

The problem with the given fix is that, even stack traces are sanitized.
IMO, you don't need to sanitize stack traces. Sanitizing log messages (
log.error("message"), exception.getMessage() ) is sufficient to prevent log
forging.

This problem affects to all products. I think we have to fix this ASAP.

Thanks.

Re: [Dev] Issue in carbon logs after changing carbon.kernel.version from 4.4.1 to 4.4.2

[Sajith Ariyarathna]

Hi All,

We are using carbon.kernel.version 4.4.2 in MDM 2.0.0 SNAPSHOT and we face
the same problem (new lines are replaced with underscores in logs). Because
of this behavior, it is very hard to debug/find problems by reading error
logs. Is there any way to by pass/stop this behavior without patching the
carbon kernel?

Thanks.

Re: [Dev] [Jaggery] response.sendError() not working for PUT and DELETE

When I ran a full test, I was able to produce 403 Forbidden for PUT and
DELETE requests..

I looked into the problem and looks like it goes all the way to Tomcat.
Jaggery error pages are implemented via Tomcat "custom error pages" option
[1]. When you call response.sendError function in Jaggery, it ultimately
calls HttpServletResponse.sendError [2] method. In Tomcat's implementation,
sendError method restarts the entire request routing/dispatching process.
So when sendError is called for a PUT or DELETE request, whole dispatching
process restarts and try to serve the configured custom error page (
*error.html*) [3]. Since *error.html* is a static resource, now the request
is handled by the DefaultServlet [4]. Now for the DefaultServlet, the HTTP
request looks like "*apply PUT/DELETE operation on error.html*". Here,
DefaultServlet's *readonly* property comes to play [5]. Default value of
the *readonly* property is true which means clients cannot modify or delete
static resources in the server. Hence "*appying PUT/DELETE operation on
error.html*" is forbidden. Therefore the 403 Forbidden is sent to the
client.

I tested with your code snippet and it works fine to me. Please check &
compare your *jaggery.conf* file with the given below.

{
  "displayName": "test",
  "logLevel": "debug",
  "urlMappings": [
{
  "url": "/debug/*",
  "path": "/lib/debugging.jag"
}
  ],
  "errorPages": {
"404": "/app/error.html"
  }
}


Thanks.

Re: [Dev] [Jaggery] response.sendError() not working for PUT and DELETE

[Sajith Ariyarathna]

Hi Thilini,

Can you share your code here?

I tested following Jaggery code. (Test was executed in* AppM 1.0.0* pack
and *Advanced Rest Client* was used as the HTTP client)

*URL Mapping in jaggery.conf: *

{

"url": "/test/*",

"path": "/lib/test.jag"

}


*File*: *test.jag*

*Code:*

var log = new Log("[testing]");

log.info("Hit for HTTP method " + request.getMethod());

response.sendError(404, "Testing page not found.");


*Terminal Output:*

[2015-10-20 10:26:52,885]  INFO - [testing] Hit for HTTP method GET

[2015-10-20 10:26:57,499]  INFO - [testing] Hit for HTTP method POST

*HTTP Output:*

404 Not Found

404 Not Found

404 Not Found

404 Not Found

404 Not Found


Since the expected output was received in above, I believe the issue is on
your side, not in Jaggery.

Thanks.

Re: [Dev] Get Absolute Path Of File In App Cloud

Hi Lasantha,

Please find my comments inline.

You cannot get the public key using Jaggery File object since File object
represent a file, not a security certificate.

*code*

This Java code should work. Set certificatePath =
"/repository/deployment/server/jaggeryapps/Parkingapp/resources/wso2defaultpub.ce"
.

Re: [Dev] Get Absolute Path Of File In App Cloud

[Sajith Ariyarathna]

Hi Lasantha,

Jaggery server runs on top of Carbon. So Java libraries which are added to
Carbon are also available in Jaggery. External Java libraries can be added
to Carbon by dropping them into 
/repository/components/lib directory (more details [1]). Don't forget to
restart the server.

Re: [Dev] Get Absolute Path Of File In App Cloud

[Sajith Ariyarathna]

Hi Lasantha,

For Jaggery, working directory is your app directory which is in
/repository/deployment/server/jaggeryapps/ .
However if you are using Java inside Jaggery, for those Java codes working
directory is carbon product directory .

Hence variable certificatePath should be
repository/deployment/server/jaggeryapps/Parkingapp/resources/wso2defaultpub.ce

Thanks.

Re: [Dev] Get Absolute Path Of File In App Cloud

[Sajith Ariyarathna]

Hi Lasantha,

Assuming,

You are reading the certificate file using Jaggery.

In your Jaggery app, certificate file is in '*resources/wso2defaultpub.cer*'
path

You can read your file using Jaggery File [1] object. Refer following
code snippet.

var certFile = new File("/resources/wso2defaultpub.cer");
var content = certFile.readAll();

[1] http://jaggeryjs.org/documentation.jag?api=file

Thanks.

Re: [Dev] Writing binary data to a file with Jaggery

[Sajith Ariyarathna]

Hi Danushka,

As per our chat you are sending base64 encoded string though a POST form
submission and read it inside Jaggery as request.getParameter("imageData")
. I believe following code snippet can help you.

var log = new Log();

// POST param 'imageData' should contain only base64 encoded string

var encodedImageString = request.getParameter("imageData"); //
encodedImageString is a string
try {

// decodedImageData is a byte array

var decodedImageData = Packages.javax.xml.bind.DatatypeConverter.
parseBase64Binary(encodedImageString);

} catch(e) {

log.error("Invalid base64 string");
log.error(e);
return;

}


try {

// file is written in {CARBON_PRODUCT_HOME}/myimage.png

var ofStream = new Packages.java.io.FileOutputStream("myimage.png"); //
assuming image type is PNG
ofStream.write(decodedImageData);
ofStream.close();

log.info("Content written successfully.");

} catch (e) {

log.error("Could not write to file.");

log.error(e);

}


Above, base64 encoded string is decoded using JABX package [1] (assuming
you are using Java6). Some other options can be found here [2].

Re: [Dev] Writing binary data to a file with Jaggery

[Sajith Ariyarathna]

Hi Madusanka,

The code snippet you mentioned [1] *does not work* in Jaggery as it meant
to be run in the client-side.

[1]
https://github.com/wso2/carbon-apimgt/blob/carbon-apimgt-v1.9.0/features/apimgt/org.wso2.carbon.apimgt.publisher.feature/src/main/resources/publisher/site/themes/default/templates/item-design/js/api-design.js#L681


Hi Dhanushka,

You can use File object [2] in Jaggery to read, write files. If you are not
satisfied with it, you can always use Java classes in your Jaggery code.

var log = new Log();

var content = "This is the content to write into file";
try {
var file = new Packages.java.io.File("myfile.txt"); // path to file
if (!file.exists()) {
log.info("File '" + file.getAbsolutePath() + "' does not
exists.");
file.createNewFile();
log.info("File '" + file.getAbsolutePath() + "' created.");
}

var fw = new Packages.java.io.FileWriter(file);
var bw = new Packages.java.io.BufferedWriter(fw);
bw.write(content);
bw.close();

log.info("Content written successfully.");
} catch (e) {
log.error("Could not write to file.");
log.error(e);
}

Re: [Dev] Do we have direct way to upload images?

[Sajith Ariyarathna]

Hi Nifras,

If you want more control over file uploading (chunking, pause/resume,
progress etc.) use a file upload plugin such as JQuery File Upload [1].

Re: [Dev] Do we have direct way to upload images?

[Sajith Ariyarathna]

Hi Nifras,

Uploading base64 encoded string rather than the binary file has some
disadvantages.

   - Encoding to base64 is not a light-weight task. Especially for mobile
   devices it can be very painful. Also for large files, web browser
   might freeze or even crash [1].
   - Usually base64 encoded string is larger than its binary file about 33%
   [2] [3]. So uploading base64 encoded string consumes more bandwidth than
   uploading the binary file.
   - In the server-side, reading a file as a base64 encoded string loads
   the whole file to the memory (RAM) once which is a bad practice. But if you
   upload a binary file, then you can get a file stream to that (
   uploadedFile.getStream()) and can read the file from that stream safely.
   - Web browsers are optimized to handle uploading large files, but not
   base64 strings.


I also took the liberty to answer your StackOverflow question [4].

Re: [Dev] Do we have direct way to upload images?

[Sajith Ariyarathna]

Hi Nifras,

You can get multiple uploaded-files inside your Jaggery code using
request.getAllFiles() function. e.g.

var files = request.getAllFiles();   // returns  map
for(var name in files) {

if(files.hasOwnProperty(name)) {

var file = files[name];

// do something with file

}

}


Thanks.

Re: [Dev] Do we have direct way to upload images?

[Sajith Ariyarathna]

Hi Nifras,

request.getFile("myFile") does not represent a physical file, rather it
represent a stream to the uploaded file. Hence you cannot "move" it using
.move("...") function. If you want to save the uploaded file, then use the
following code snippet.

var uploadedFile = request.getFile("myFile");
var savedFile = new File("/path/to/save/location/" +
uploadedFile.getName());
savedFile.open('w');
savedFile.write(uploadedFile.getStream());
savedFile.close();


Thanks.

Re: [Dev] [Caramel] Adding more custom Handlebars helpers to Caramel

[Sajith Ariyarathna]

Hi Manu,

Please find my comments inline.

-1 *ifCond* and *selectIf*

 I agree with your view. Since Mustache and Handlebars follow the *logic-less
template* approach, Caramel should also follow it.

However there are some circumstances where you have to put some logic in
the template. For example, in [1] we have used selectIf helper to determine
the proper CSS class for some action buttons. Before introducing
selectIf helper,
these CSS classes were hard-coded in this [2] .js file (which is in the
server-side). Hard-coding CSS classes is acceptable in HTML templates and
client-side JavaScripts, but not for other server-side .js or .jsg files.
That's why we introduced the selectIf helper.

+1 for *for*
>
The {{index}} expression has been introduced to the {{#each}} block helper
in Handlebars 3.0.3 version. However startIndex, endIndex and jump optional
parameters of the proposed for helper can be helpful. For example,
displaying only certain number of items based on a user input (see below
image). So, adding for helper will be helpful.

Thanks.

Re: [Dev] [Caramel] Rendering HTML using Caramel in client side

[Sajith Ariyarathna]

Hi Rajith,

It seems like Caramel client library has a dependency that I don't know
about. I have found out that following scripts (libraries) are required to
run Caramel in the client-side.


async.min.js
caramel-client.js
caramel.handlebars.client.js


Can we add about these dependencies to the README [1] file in the Caramel
repo, so that everyone can see it.

[1] https://github.com/wso2/caramel/blob/master/README.md

Thanks.

[Dev] [Caramel] Adding more custom Handlebars helpers to Caramel

[Sajith Ariyarathna]

Hi All,

For AppM we have implemented few custom Handlebars helpers [1]. Since they
are very helpful, we like to suggest them to add to the Caramel framework.
We suggest following 03 helpers.

*ifCond*

Conditional if block which can be used with a single logical expression.
ifCond helper supports ==, !=, ===, !==, <, <=, >, >=, &&, || and
typeof operators.
(see [2])

*for*

Iterates over an array and iteration manner can be customized. Also, index
of the current iteration can be access as {{index}}. (see [3])

*selectIf*

For the given value, outputs the result based on the specified
'value-result' map. Very similar to the switch-case clause. (see [4])


Thanks.

[Dev] [ES] [AppM] Back-porting "Per Version App Commenting and Rating" from ES 2.0 to AppM 1.1

[Sajith Ariyarathna]

Hi ES Team,

For the upcoming AppM release we are hoping to implement "Per Version App
Commenting and Rating" feature. Following are the basic requirements of
this feature.

   - In the Store, user should be able to comment and rate a published
   version of an app.
   - However, comments of older versions should be displayed under newer
   versions as "For a previous version: ".
   - When calculating the overall rating of an app, ratings from all
   versions of that app should be considered.

We are hoping to back-port this feature form ES 2.0 to AppM 1.1 . Does ES
2.0 has this feature (or similar one) in the social plugin?


PS: If two assets are two versions of the same app, then their 'name'
attribute and 'provider' attribute are equal and 'version' is different.

Thanks.

Re: [Dev] [Caramel] Rendering HTML using Caramel in client side

[Sajith Ariyarathna]

Hi Dakshika,

I followed your example (see [1]) and implemented my solution. Here is my
code. Here updateTableColumns function is called when the AJAX call is
completed successfully.

/**
 * Updates table cells using Caramel engine.
 * @param assetData {Object} asset
 * @param statusTd {jQuery} table cell to be updated in the STATUS column
 * @param actionsTd {jQuery} table cell to be updated in the ACTIONS column
 */
function updateTableColumns(assetData, statusTd, actionsTd){
console.log(assetData);

caramel.render ('list-assets.status', assetData, function(info,
content){
console.log(content);
statusTd.find('span').html(content);
});
caramel.render ('list-assets.lc-actions', assetData, function(info,
content){
console.log(content);
actionsTd.find('span').html(content);
});
}


But now I get a "*Uncaught ReferenceError: async is not defined*" error in
the browser console. This error is thrown from the
'caramel.handlebars.client.js' file (line 107 [2]). How can I resolve this
issue?

PS: 'handlebars.js', 'caramel.handlebars.client.js', 'caramel-client.js'
scripts are included in the web page in this order.

[Dev] [Caramel] Rendering HTML using Caramel in client side

[Sajith Ariyarathna]

Hi All,

I want to update a portion of the web page using Caramel. Necessary data
(JSON) is obtained through an AJAX call. How do I accomplish this task? Any
examples will be very helpful.

PS: caramel.handlebars.client.js [1] and handlebars-1.1.2.js [2] acripts
are included in the page.

Thanks.

Re: [Dev] [Java] StackOverflowError when serializing a deeply nested object

[Sajith Ariyarathna]

Hi Ramindu,

I think you are talking about this [1] StreamEvent class.

StackOverflowError can happen when serializing large linked-list type
objects. This [2] answer may shed some light on your problem. In the last
part of the answer, quote

... But serialization is vulnerable to stack overflow for certain kinds of
> structures; for example, a long linked list with no special writeObject()
> methods will be serialized by recursively writing each link. If you've got
> a 100,000 links (nodes), you're going to try to use 100,000 stack frames,
> and quite likely fail with a StackOverflowError.
>
It's possible to define a writeObject() method for such a list class that,
> when the first link (node) is serialized, simply walks the list and
> serializes each link (node) iteratively; this will prevent the default
> recursive mechanism from being used.


So, implementing writeObject() method for the linked-list (which has
StreamEvent nodes) will solve your problem.

Re: [Dev] API Manager associating a new version of an API with its previous version

[Sajith Ariyarathna]

Hi Uvindra,

As pointed out by RuwanA, AppM had a similar problem when creating a new
version of a web app based on an existing version. In AppM, when
'Publish'ing version *2.0.0* of web app *Foo* (which was created from *Foo*
version *1.0.0*), version *1.0.0* is 'Un-publish'ed (because only one
version of a web app is shown to end-users in the store) and subscriptions
from version *1.0.0* are moved to version *2.0.0*. This is not exactly your
situation in APIM, but you can see that subscriptions are moved to the new
version when it is 'Publish'ed.

Suggestion: you should give the option to the Publisher to decide whether
to copy or move subscriptions to the new version. You can give 03 options,
"Copy Subscriptions to v2.0.0", "Move Subscriptions to v2.0.0" and "Do
Nothing". I believe it will improve the user experience for API Publisher.

As suggested by RuwanA, keeping the 'parentID' in the asset or in the DB
will also help to maintain a version hierarchy and in future releases you
can use that data to do API grouping or to show a versioning tree.

Thanks and Regards.

Re: [Dev] Get values from javascript or html into jaggery

[Sajith Ariyarathna]

Hi Aaquibah,

You cannot use 'document.getElementById()' function in Jaggery, because
'the document' (HTML page) is in the client-side and Jaggery runs in the
server-side. If you want to access a value from a HTML page, then you have
to do a form submission (POST request) or a AJAX call from client-side.

We can help you further if you can elaborate your use-case and code.

Thanks.

Re: [Dev] [Jaggery] Download files from URL

[Sajith Ariyarathna]

Hi Vinod,

Can you use Java in the scenario? If so, then you can implement this task
in Java and call that Java method inside your Jaggery code. I think
implementing this task using Java will be lot easier.

Thanks.

Re: [Dev] [ES] [AppM] 'Name' and 'Display Name' field in App Manager

[Sajith Ariyarathna]

Hi Chathura,

IMO naming an unique attribute as "Name" is a bad practice. I think naming
it as "App ID" or "Asset ID"or some other name which indicates attribute's
uniqueness will be a better approach.

Also name would give an incorrect message to the user since the value of
> the name is visible to the user.
>
Instead of "Name, "Display Name" is always shown to the end-user in AppM
store for both web apps and mobile apps. (see also [1]).

Thanks & Regards.

Re: [Dev] Jaggery debugging issue

[Sajith Ariyarathna]

Hi Vinod,

I tried to debug Jaggery in several WSO2 products (APIM, APPM) using both
Eclipse and IntelliJ IDEA, but failed to do so. Somehow, "-DjsDebug"
parameter is not passed to the Jaggery server when running via
'wso2server.sh' script.

Thanks & Regards.

Re: [Dev] Jaggery debugging issue

[Sajith Ariyarathna]

Hi Dinusha,

AFAIK debugging Jaggery in Eclipse has some known issues. I suggest to use
the exact versions of jars as specified in the documentation [1]. Also, you
can try to debug Jaggery in IntelliJ IDEA by using this [2] plugin.

[2] https://plugins.jetbrains.com/plugin/1613?pr=

Thanks.

Re: [Dev] [Jaggery] Calling javascript function from .Jag file

[Sajith Ariyarathna]

Hi Himasha,

Jaggery scripts runs in the server-side. Hence, you cannot use client-side
JavaScript functions such as 'alert'. Please make sure that "/js/actions.js"
have only server-side functions.

Thank you.

Re: [Dev] [AppM] Issue with clustering AppM with large mobile apps

[Sajith Ariyarathna]

Hi Chathura,

My suggestion is to give the capability of specifying a location (path) to
the admin user.

Admin user can specify a location in the configuration file
(app-manager.xml). Then he can mount that location to all nodes in the
cluster. So, in Java we can access that location.

This approach have several advantages:

   - High fault tolerance. Because we can safely assume that admin user
   will choose a secured location with a low downtime.
   - No extra effort to read/write data, because location will be mounted
   to every node.
   - Less implementation burden as we don't have to use any extra libraries.


Cheers.

Re: [Dev] Use of wso2carbon-version.txt

[Sajith Ariyarathna]

Hi Kalpa,

AFAIK *wso2carbon-version.txt* file is used in following scripts.

bin/wso2server.bat
bin/wso2server.sh
bin/carbondump.sh
bin/carbondump.bat

As you mentioned, *wso2carbon-version.txt* is used in above files just to
print/echo carbon framework version.
You can use grep -r 'wso2carbon-version.txt' * command in CARBON_HOME
directory to find usage of *wso2carbon-version.txt* file.

thanks and regards.

Re: [Dev] [Carbon][AppM] Calling OSGi service in Jaggery gives a NullPointerException

[Sajith Ariyarathna]

I tried different approaches with
org.wso2.carbon.user.api.UserStoreManager OSGi
service, however I couldn't overcome the NullPointerException. I think one
must initialize the UserStoreManager service before using it, but couldn't
find an initializing method.

*Solution:*
Instead of using UserStoreManager OSGi service, I used
org.wso2.carbon.user.core.service.RealmService OSGi service. Using the
RealmService you can get TenantUserRealm object for a given tenant ID. From
that you can get an UserStoreManager object. This object (usManager) has
all functionality of UserStoreManager OSGi service. Refer following sample
code.


var carbon = require('carbon');
var store = require('store');
var server = store.server;

function test(role){
var realmService =
carbon.server.osgiService('org.wso2.carbon.user.core.service.RealmService');
var tenantId = server.current(session).tenantId;
var usManager =
realmService.getTenantUserRealm(tenantId).getUserStoreManager();
return usManager.getUserListOfRole(role);
}



Thanks & regards.

Re: [Dev] Cross database pagination

[Sajith Ariyarathna]

IMO, I don't think you can have an universal solution. Paging is not
included as a standard feature in SQL specifications (see SQL
standardization <http://en.wikipedia.org/wiki/SQL#Standardization>). Hence,
pagination is an extension for DBMS. So different vendors have implemented
it in different manners. Therefore you cannot have an universal solution.
You have to tackle different DBMS manually.

Even though you cannot have RDBMS universal solution, you can use JPA and
it will handle different DBMS for you. E.g.
   Query q = ...;
   q.setFirstResult (0);

  q.setMaxResults (10);

Re: [Dev] Best Way to find two files are equal in test cases.

[Sajith Ariyarathna]

Hi Tharindu,

I think this is caused by "chunking" in input streams. It might happen
because of HTTP protocol or a bug in Java, I'm not sure.

As an alternative solution you can run the MD5 command and compare its
output. Like this,


public String getMd5Checksum(String filePath) throws IOException {

final String md5Command = "md5sum "; // Linux 'md5sum', MacOS 'md5'

Process p = Runtime.getRuntime().exec(md5Command + filePath);
Scanner scn = new Scanner(p.getInputStream());
String rv = scn.nextLine();
scn.close();
return rv;
}

Re: [Dev] Handling Throwable in catch block

[Sajith Ariyarathna]

I think I have found a bug in JDBCUserStoreManager class at persistUser
<https://github.com/wso2/carbon4-kernel/blob/master/core/org.wso2.carbon.user.core/src/main/java/org/wso2/carbon/user/core/jdbc/JDBCUserStoreManager.java#L1159>
 method.

In line 1166
<https://github.com/wso2/carbon4-kernel/blob/master/core/org.wso2.carbon.user.core/src/main/java/org/wso2/carbon/user/core/jdbc/JDBCUserStoreManager.java#L1166>
a
database connection is created by calling the getDBConnection()
<https://github.com/wso2/carbon4-kernel/blob/master/core/org.wso2.carbon.user.core/src/main/java/org/wso2/carbon/user/core/jdbc/JDBCUserStoreManager.java#L976>
method which throws SQLException and UserStoreException. If it throws an
exception, catch clause [ catch (Throwable e) ] in line 1263
<https://github.com/wso2/carbon4-kernel/blob/master/core/org.wso2.carbon.user.core/src/main/java/org/wso2/carbon/user/core/jdbc/JDBCUserStoreManager.java#L1263>
will catch it and tries to rollback the database connection.
But dbConnection is null at this moment, and it will result a
NullPointerException; which is not handled.

My suggestion to fix this bug is to handle the exceptions of creating the
database connection (at line 1166
<https://github.com/wso2/carbon4-kernel/blob/master/core/org.wso2.carbon.user.core/src/main/java/org/wso2/carbon/user/core/jdbc/JDBCUserStoreManager.java#L1166>)
in a separate try-catch block.
