To get hold of the tool at the moment you are going to have to do a little bit of work with svn and maven. So you need to check out the head of
https://svn.java.net/svn/tyrus~source-code-repository/trunkand then perform a
mvn packageon the etc/client-cli sub project. Depending on the state of the maven repository you might need to do a
mvn install -DskipTests=trueon the root project first.
You can now find the executable jar in
.../tyrus/ext/client-cli/targetcalled something like
tyrus-client-cli....jar. This has been shaded so it contains all of the required deps to run. Simples.
The tool currently allows you to send text and ping messages. It can receive binary messages but it just displays the hex values of up to the first 1024 bytes.
So you can either pass in the ws:// URL as the single command line argument or you can connect using the open command once the tool is running. Here are some very simple commands along with a response from a simple echo web socket service.

I can see this being very helpful when trying to debug a web socket service and you want to remove the web browser out of the equation. It is implemented using JLine2 so it behaves like a native command line tool so is pleasant to use.
