I am working on a predictive on IBM SPSS modeler with an SVM and then uploading the PMML to the cloud to provide it as a service, but even when I use the automated system to send the request it gives me ArrayOutOfBounds exceptions. Please let me know if you need more details

I'm tasked with creating a hyperledger application that will represent a consortium of same-skilled organizations.
I have the barebones prototype with a network of 2 orgs, built by following the fabric-samples example that I created as a capstone project; I am looking to upgrade the application to a production level.
My question is, is there a GUI/platform available to create and maintain hyperledger fabric networks?
What are the alternatives for tools like the Console?
What would be the best way to start building such an application considering the goal is to get to the production level?
Is IBM Cloud Blockchain Platform the best option for me?
Thank you for taking the time to reply.
I know of Hyperledger Console. I have used it previously for school projects. But can it be used to create and maintain+govern a production-grade HLF app?
IBM Blockchain Platform on IBM Cloud is withdrawn (https://www.ibm.com/common/ssi/cgi-bin/ssialias?htmlfid=872/ENUSWP22-0062&infotype=AN&subtype=CA). But the console is open sourced as https://github.com/hyperledger-labs/fabric-operations-console
I'm using Talend for Data Integration v 7.3.1.20200219_1130 and I want to use tREST_request and tREST_response as server side in order to convert an Excel file to XML file.
My problem is that I cannot find both components in ESB section, as described in Talend documentation, I looked also in "Palette Settings", there's only tRESTClient.
I'm wondering if this is a version problem (those components are omitted in this version) or those components are not avaible in free version?
You have to download Talend Open Studio for ESB in order to get those components.
I don't know why, but this version is not available anymore on talend website. You have to go to sourceforge to find it.
https://sourceforge.net/projects/talendesb/
With Talend Open Studio for ESB you can develop job to provide services (through tRestRequest/tRestResponse components, are SOAP components), as well as developing classic Talend Data Integration jobs.
I am using Text to Speech in Watson Studio. The output file is '.wav'. Does anyone have got any idea where is the file stored? I want to download it from the IBM cloud to my pc. How should I do this? I have searched entire cloud storage, but couldn't find the speech file.
When running the TTS API from within Watson Studio on Cloud notebooks, the files you write go to the underlying python runtime container's filesystem, which is not persistent.
So, you would have to explicitly copy that file to Cloud Object Storage.
An easy way to do that in WSC is to use the project_lib API (see https://dataplatform.cloud.ibm.com/docs/content/wsj/analyze-data/project-lib-python.html), which will let you create a Data Asset in your project.
You could also use the COS Client API https://ibm.github.io/ibm-cos-sdk-python/reference/services/s3.html#S3.Client.upload_file to copy that file to an arbitrary bucket that you have access to.

Due to IBM doesn't provide free plan for IBM Blockchain anymore, I come up with with solution to integrate Watson IOT to Hyperledger Fabric instead of IBM Blockchain.
I found this document, it say that Watson IoT Platform blockchain integration supports connecting to both IBM Blockchain fabrics and Hyperledger fabrics
(in section Config Blockchain IBM environment)
But I can not find any guideline.
Anyone can help?
I have several related comments:
1) The page you linked to shows an early version of the IoT Contract Platform that I authored. I have not been funded to port it to Hyperledger v1 so it must be considered deprecated at this time. Instead, I suggest that you get comfortable with the Hyperledger Composer, which provides a huge development environment and a powerful data modelling language.
https://hyperledger.github.io/composer/introduction/introduction.html
2) Which leads me to IBM's free container service. If you want to get started with IBM Blockchain on Bluemix, you can create a free kubernetes cluster using the instructions found here.
https://ibm-blockchain.github.io/
The "create_all" script gives you a working fabric on a lite cluster (as in free) with hyperledger composer running (with playground) and with a copy of the example02 ubiquitous sample Go chaincode running on the same channel.

EDIT: As for the iot connection, you can use node-red to create iot apps that will catch your events on a topic and then forward them to the blockchain. This is for experimentation of course, but you will get the idea how an application must be written.
If you want to follow my "partial state as event" pattern in composer contracts, you can look at the deep-merge npm project and mimick that code while we wait for the node based chaincode that is coming in Fabric 1.1, at which time I hope that we can import it as normal in our business network js files.
Using deep-merge requires that you create your own transactions for create, replace, update and delete in your smart contracts, but these are straightforward. The bonus is that it is also easy then to emit custom events defining what happened to listening applications.
I think you will like these two technologies together.
Instead of using the IBM Blockchain, you should create your own Blockchain. You should use the Hyperledger Fabric for that. You have the documentacion about it here. I suggest you to start reading from the Building Your First Network chapter.
Then, you should integrate your Blockchain with the Watson IoT.
We have been exploring RapidMiner Cloud recently .We found that it internally uses AWS and can be used to run heavy processes.
Based on our learning, we could conclude that RapidMiner Cloud is really a rapid miner server running on cloud.
But we could not find ways to get REST API's and dashboard capabilities that locally hosted RapidMiner server provides.
If we use Rapid Miner Cloud, How can we get RestAPI capabilities.
Thanks
the RapidMiner Cloud is more an extension to run Studio processes on the cloud and not a complete RapidMiner Server with a RestAPI.
If you want to use a RestAPI you have to setup a complete RapidMiner Server instance, which could also be done on AWS or similar systems.
Best,
David
