On Mac and Linux, create a random file (https://stackoverflow.com/questions/257844/quickly-create-a-large-file-on-a-linux-system)
dd if=/dev/urandom of=random-test-file-100m bs=1024k count=100
$ dd if=/dev/urandom of=random-test-file-100m bs=1024k count=100
100+0 records in
100+0 records out
102400000 bytes transferred in 10.143507 secs (10095128 bytes/sec)
This is a random file. You should also use shasum -A 256 and make sure the file you are using for test is what you get back. Do also remember 1024 bytes to a KB… use blocksizes of 1024
On linux, create a fast file (https://stackoverflow.com/a/11779492):
fallocate -l 100M test-file-100m
This takes less than a second. The file is not good for testing random behaviors with large files as the generated file is huge, but the same bytes repated for 100M.
To check the size of the sample files, you can use human readable format settings (https://unix.stackexchange.com/a/281113).

Here are some tips for Maven Java Projects in Eclipse.
#1 If you pom.xml is missing maven-compiler-plugin, Eclipse (when you do Maven > Update Project), defaults the compiler level for the project to 1.5.
Now, it gets even more tricky… if your project has defined features that are from Java 1.6, 1.7 or 1.8
#2 if you your web.xml defines a version not compatible with a project facet you depend on, you get a lot of problems/errors
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"/>
Convert the web.xml to 3.1, and compatibility should now be fixed
<web-app id="WebApp_ID" version="3.1" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd">

#4 Make sure you don’t have two web.xml files… the convert dynamic web project to maven project does some funky stuff.
For developers that are beginning to investigate oAuth and IBM Connections Cloud, you’ll find two interesting things about the oAuth 1.0a web flows and the oAuth 2.0 web flows.
1- The flows don’t support extra on the flow – for instance the state parameter. state=XYZ123
2- The oAuth 2.0 flow expects callback_uri, not the common redirect_uri parameter.
The various flows are located at
oAuth 1.0a web flow and oAuth 2.0 web flow
While I was working with a fellow developer building an integration for IBM Connections on premises, I found out about a couple of key items with the OAuth Provider.
1 – You can see a JSON Array of the Current User Tokens, when logged in as that user.
Login to IBM Connections
Look at the JSON Data to see the Granted Applications for the Logged in User
2 – You can see all the applications which are granted user oauth tokens – automatically authorized and manually authorized.
Navigate to https://sbtdev.server/common/oauth/apps?autoAuth=true
3 – OAuth Whitelists
, you can update your OAuth whitelists based on the client-id you set. http://www-01.ibm.com/support/ docview.wss?uid=swg21627911
“As a measure to reduce hassle to users for trusted OAuth clients, IBM Connections implements an extension to the OAuth protocol that allows whitelisted clients to skip the authorization request when utilized from within the Connections user interface. In order to list an application as a trusted auto-authorization enabled client, an administrator must perform steps that are covered by the product documentation topic http://www-10.lotus.com/ldd/ lcwiki.nsf/dx/Registering_an_ OAuth_client_with_a_provider_ ic40 . ”
Edit the connectionsProvider.xml in the Deployment Manager profile.
Synchronize your nodes, and restart the server.
Volia… you have
