WS02 GREG ERROR when deploying carbon archive - wso2

I am trying to upload a carbon archive in the registry. Everything seems to be OK when I add a new application, but the log show the following error:
An error occurred while determining the latest version of the resource at the given path:
/_system/governance/trunk/wsdls/.... (path to the wsld deployed)
org.wso2.carbon.registry.core.exceptions.RegistryException: Failed to obtain the user realm for tenant: -1
I log with the admin user and everything that should be upload is in the registry.
Any help?
Thanks,

I tried to reproduce this with WSO2 G-Reg 4.1.1 but unable to reproduce it.
Please indicate the G-Reg version you have tried out this scenario.
When you upload the CAR file from Management Console, make sure to remove the previous version of the same CAR file before you upload the newer version.
This error seems to be related versioning.
Since you remove the previous version of the CAR file, the aforementioned suggestion will solve your problem.
Thanks and Regards,

WSDLs are stored in the /_system/governance/../trunk/wsdl/.. location if you upload them via management console or upload the resource from Developer Studio Registry Browser.
But when you deploy a WSDL via a C-App, when creating the registry resource from Developer Studio, you specify a location to deploy. Hence the WSDLs deployed via C-Apps are deployed to this specified location but not the other location.
Therefore from your proxy service, you should refer the location you have mentioned to deploy your WSDL but not the default location.
Once you fix this, your Proxy service will work fine.
Thanks and Regards,

WSO2 EI: Registry issue

Frequently, WSO2 EI server getting crashed in our local environment with registry issue and every time this issue occurred I used to change the server bundle to sort this out is there any permanent solution to fix this issue?
If possible can someone explain why this issue occurred it would help me to understand why it's occurring.
This issue can be observed if the <registryPath> is not configured in Salesforce init configs. The connector might add a corrupted entry to the registry when invoking the service due to this missing config. In the latest versions of the Salesforce Connectors, this value has been set by default, hence you do not need to provide them separately.

Authentication Error when Trying to Log into WSO2 IoT Server - Device Management Console in wso2-iot-3.3.0

I followed the instructions in the link (https://docs.wso2.com/display/IOTS330/Enterprise+IoT+solution) in Windows to start WSO2 IoT server. So, broker, iot-server and analytics are started. But, when I'm trying to log in to the device management console using admin login or the login credentials I created, it gives me an authentication error.
I tried the solutions in this answer (Not able to access WSO2 IoTS Device Management Console in wso2-iot-3.3.0 when logged in 'admin') also (Reducing Java version to 1.8.0_144 and making the compression parameter to off in all the catalina-server.xml files). But any of it didn't work for me.
I have attached the screen shots of the error. Please help me to go through this! Thank you.

Error description in iot-server console-Part 2
This is related to the issue mentioned in the github issue mentioned below and it seems, it is already fixed in latest master.
As a quick workaround you could try to modify the startup script files (bat files in this case) and add the changes mentioned in the above git issue.
For example, you can change the file modules/distribution/src/core/bin/iot-server.bat at line number 73 as below.
FOR %%D in ("%CARBON_HOME%\wso2\lib\commons-lang*.jar") DO set CARBON_CLASSPATH=!CARBON_CLASSPATH!;".\wso2\lib\%%~nD%%~xD"
Similarly do the same change as above for files mentioned below as well.
modules/distribution/src/core/resources/profiles/backend/iot-server.bat
modules/distribution/src/core/resources/profiles/keymanager/iot-server.bat
modules/distribution/src/core/resources/profiles/manager/iot-server.bat
This should resolve the issues you are facing.

Error Configuring WSO2 data analytics server

I'm currently experimenting/working on WSO2. What i'm trying to do is to have Data Analytics server configured. I started by following the below specified URL
https://docs.wso2.com/display/AM210/Configuring+APIM+Analytics#9d6747f5c0074928b18599abe472987d (Quick Steps)
After performing all the steps, i get the following issue on APIM cmd prompt
YES Its pretty evident from the error that no such table exists BUT that is exactly the issue i'm facing. What could really be the cause here?
Consider the following points:
I've not followed ALL the steps mentioned on
https://docs.wso2.com/display/DAS310/Getting+Started (BUT are they
required?)
In the installation prerequisites for DAS, JDBC-compliant Connector for Java is required which I've not yet installed (BUT its not mandatory at the same time)
Most of the QUICK STEPS for the configuration of DAS in the specified URL i.e. https://docs.wso2.com/display/AM210/Configuring+APIM+Analytics#9d6747f5c0074928b18599abe472987d where already in place and i only had to
Set Up JDK, ANT, Maven
enable the analytics section in the API-M_HOME/repository/conf/api-manager.xml
add log4j.rootLogger=, DAS_AGENT to API-M_HOME/repository/conf/log4j.properties
add snappy-java_1.1.1.7.jar to DAS_HOME\repository\components\lib
Yet the issue persists, Do let me know of what you think. Thank you
Since you are following quick start guide please extract the WSO2 API Manager and the WSO2 API-M Analytics distributions (zip files), to the same directory (preferably an empty directory).
Also, you need to generate some traffic to the published APIs in order to analytics server to create this table for the first time.

Integrate WSO2 APIM190 with DAS300

Since I already know APIM 1.9.0 is default support BAM, that UI is for deploy the BAM analytics artifacts called toolbox. When you work with DAS, you should leave Data Analyzer Configurations as blank. And need to deploy artifacts(CaPP) manually on DAS .
I seached and found below link which might be helpful:
http://blog.rukspot.com/2015/09/publishing-apim-runtime-statistics-to.html
But the bad thing is for unknown reason I tried times to access this link ,,all failed.
Can anybody help to paste the content of above link here or just send a private mail to me via my mail : menglong567#aliyun.com
That would be very appreaciated !
Please find the official documentation for WSO2 API-M 1.9.0 statistics configurations in here.
All the necessary information is covered in the official doc.

Deploy Rule Service WSO2 Business Rule Server

I was trying to deploy a rule service with WSO2 Business Rule Server
I exactly followed this link
http://docs.wso2.org/wiki/display/BRS200/Creating+and+Deploying+the+Rule+Service#CreatingandDeployingtheRuleService-RuleServiceWizard
I also made the jar file from 3 different class files:
OrderAccept.class OrderReject.class and PlaceOrder.class
I am trying to deploy the server with wizard in the end I got this error

Anyone could help me where I might make mistakes?
It seems your jar files are not properly picked. One reason I can think of it, your axis2 archive has wrong folder structure. I am talking about the rule service upload mechanism. You may see there is a folder structure recommended in the documentation. After creating the .aar file, extract it and see whether you have the same folder structure. If it differs from the recommended one, your jar files will not get picked.
I've tried the same example and it's also giving me the same error(both methods, Rule service Upload and Rule Service Wizard). The folder structure that #Amila was suggesting seems to be ok according to the documentation. What I recently found is this link http://wso2.com/library/articles/2013/05/eclipse-plugin-wso2-business-rules-server from which I quote "Previously WSO2 BRS artifacts (aar/car) were created using the web UI rule wizard or creating the artifact by combining several artifacts. With the new WSO2 Developer Studio plug-in for rule services, one can easily create a complete deployable BRS artifact using the Eclipse IDE. Developers can easily create WSO2 BRS artifacts using this tool, and deploy it in the WSO2 Business Rules Server." What I'm guessing is that this new method/tool would substitute the "old" methods(upload and wizard). Give it a try.
