oslc / iotp-adaptor Goto Github PK

Large preview dialogs are either blank or show the same content as the small preview. This is because handling the large preview uses the HTML rendering, and this is currently modified by user code to redirect the user to the Watson IoT platform. The code to render HTML is essentially dead code.

We need updates to the Lyo Designer templates to generate separate REST services for large previews (same as for small preview). This will provide flexibility for implementations.

I followed the steps in the docs but the iotp fails to launch.

Caused by: java.lang.NullPointerException: inStream parameter is null

This line of the CredentialsFilter.java code tries to load /config.properties.
85 configProperties.load(TRSObject.class.getResourceAsStream("/config.properties"));

Is config.properties a file? This file does not exist. Is that because it's in a .gitignore? The instructions do not mention this file. It is referred to in multiple parts of the code. Only two other lyo projects on GitHub have a config.properties file (org.eclipse.lyo.adapter.magicdraw/configuration/config.properties), oslc4simulink/configuration/config.properties) but I have no information about where this file should go and what should be in this file, if that is really the problem.

I want to get iotp-adaptor running, but what step am I missing?

This file should be stored in a secure place on a sample server.

apiKey and user credentials - should be encrypted.

• Need to create a utility program to encrypt the password:

import com.ibm.team.repository.common.util.ObfuscationHelper;
// use this to encrypt the apiKey and TRS user's password to put in config.properties
encryptedPassword = ObfuscationHelper.encryptString(password) 
System.out.println(encryptedPassword)

• Then use this to decrypt the password stored in the config.properties file

password = ObfuscationHelper.decryptString((String)clientProperties.getProperty("password"));

This is because the base and change log are not persisted across server restarts. The TRS provider should be viewed as a simple sample that provides minimal TRS capability. There's lots more that would need to be done for a production TRS provider.
