Microprofile Quickstart fails

[karianna]

The quickstart instructions fail to bring up a working conference app. An empty speakers page pops up. Various warnings/errors are in the log attached.

Can't attach log because GitHub UI is broken again

@katheris it looks like the error is coming out of the vote service:

[ERROR] Async process failed for: [java, -jar, target/microprofile-vote.jar]

@iainduncani - Thanks - I was lazy and put up a pretty poor bug report.

@karianna I'm struggling to recreate this both on Windows and Linux... Judging by the output it is finding the vote JAR (located at microprofile-vote/target/microprofile-vote.jar) but failing to get very far in launching it as no server output is coming out from the Liberty server. A working output would look something like this:

[INFO] --- exec-maven-plugin:1.5.0:exec (vote) @ microservice-start ---
[INFO]
[INFO] --- exec-maven-plugin:1.5.0:exec (ui) @ microservice-start ---
Extracting files to C:\Users\IBM_ADMIN\wlpExtract\microprofile-vote_799374421263414\wlp

As the first thing we do is extract the JAR to your home directory I wonder if this is a permissions issue. The command will try to extract and run the server in your /wlpExtract directory, I presume the mvn command running this will have write permission to there?

[karianna]

Hi @iainduncani - I'm running on Mac OS X 10.12.1 - I don't think permissioning is an issue as I have an I have an empty ~\wlpExtract directory created for me as part of the run.

[katheris]

@karianna I cannot reproduce this on linux, currently having npm issues on Windows so can't verify there. Have you run it fine in the past? Can you verify what previous version worked so we can narrow down what has changed?

[karianna]

The quickstart mvn package -Pstart -pl :microservice-start command has never worked for me no. The very latest version has the schedule service coming up in the UI, the other 3 services still fail. I'll try to run the services individually as described in the docs and see if I can narrow it down.

[karianna]

When I start the vote service java -jar target/microprofile-vote.jar by itself it succeeds:

and then visiting the URL I get what's expected.

Call to io.microprofile.showcase.vote.api.SessionVote:info([]) returned Microservice Session Vote Application

[karianna]

So if I start the liberty service by itself and then run the quick start I see more of the conference app, the first three tabs work. Unfortunately the vote UI is still blank.

[katheris]

@karianna Strange that it works by itself but doesn't work as part of the set. The vote service UI doesn't currently display anything as there isn't a way to add votes, so there are no votes to display, the page should just say Votes at the top (although the writing is hard to see due to the colour). I believe @AndyGee has been working on some updates to integrate the vote service with the UI properly and I've been chatting to some people in my team to find someone with the skills to update it.

[katheris]

@karianna have you run mvn package or mvn install before running mvn package -Pstart -pl :microservice-start? Is it possible that your other projects weren't built properly? The -pl command will only run the microservice-start project so you would need to have built the other ones previously, and I did change the name of the jar file so perhaps you had an older version lying around and that's why it couldn't run?

[karianna]

@katheris - Thanks for sticking with this! At the microprofile-conference level I run:

mvn clean install
mvn package -Pstart -pl :microservice-start

The mvn clean install is successful. Then I get the usual issues:

• Speakers UI shows no details beyond the header 'Speakers Search for your favourite speaker' and a search field
• Sessions UI shows no details beyond the header 'Sessions Search for your favourite session' and a search field
• Schedule UI works!
• Vote UI just shows the hard to read Vote title (perhaps this is working as expected in that case)

[katheris]

There have been a whole bunch of changes in recently. @karianna are you still having problems? I believe the vote service should currently show a pie chart

[karianna]

Updated to canonical master HEAD. Things have improved although no speakers or schedules data is shown in the UI and I get errors like:

[katheris]

Sounds like you need to do a clean install? There have been node module changes

[karianna]

@katheris - Yep tried that, same result. Schedule works, vote service has a pie chart but nothing for speakers or sessions
