[Opaltoolkit-users] Troubles setting up the opal server (services run, but can't get the results)

[Jacob D. <jac...@gm...>]

I'm interested in developing some opal services and so am trying to set up
a "toy" opal server on my local computer. I'm having trouble accessing and
downloading the results. Here are the steps I've followed (probably more
detail than you need!):

1) Downloaded tomcat 8.0.5, got it working.

2) Downloaded opal 2.5.

3) Edited $OPAL_HOME/etc/opal.properties. Uncommented the
"working.dir=opal-jobs" line, otherwise left the file the same.

4) Made no changes to $OPAL_HOME/etc/opal.xml

5) Ran the following commands:

cp $OPAL_HOME/etc/opal.xml $CATALINA_HOME/conf/Catalina/localhost/
cd $CATALINA_HOME/webapps
mkdir /scratch/opal-jobs
ln -s /scratch/opal-jobs opal-jobs

6) Edited $OPAL_HOME/build.properties. Changed line: catalina.home =
/scratch/Programs/apache-tomcat-8.0.5

7) From the opal-ws-2.5 directory, ran: ant install (BUILD SUCCESSFUL)

8) Added this line to my .bashrc: export
JAVA_OPTS="-Djava.awt.headless=true"

9) Started tomcat and visited localhost:8080/opal2/happyaxis.jsp:

=====================

Found JAXP implementation ( javax.xml.parsers.SAXParserFactory ) at an
unknown location

Found Activation API ( javax.activation.DataHandler ) at an unknown location

=====================

10) Copied the following toy opal XML file I made to $CATALINA_HOME/deploy:

<appConfig xmlns="http://nbcr.sdsc.edu/opal/types"
           xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <metadata appName="parrot">
    <usage>Here's some usage</usage>
    <info>Some info, dude.</info>
    <types>
      <untaggedParams>
        <param>
          <id>text</id>
          <paramType>STRING</paramType>
          <ioType>INPUT</ioType>
          <textDesc>Here's what will be parroted.</textDesc>
        </param>
      </untaggedParams>
    </types>
  </metadata>
  <binaryLocation>/bin/echo</binaryLocation>
  <defaultArgs></defaultArgs>

<jobManagerFQCN>edu.sdsc.nbcr.opal.manager.ForkJobManager</jobManagerFQCN>
  <parallel>false</parallel>
</appConfig>

11) The new service didn't appear at
http://10.0.0.9:8080/opal2/dashboard?command=serviceList. I noticed that
tomcat kept creating a directory at $CATALINA_HOME/deploy/deploy/. I moved
my xml file there, and it did show up in the opal dashboard.

12) To test the new opal app, I filled out the web form at
http://localhost:8080/opal2/CreateSubmissionForm.do?serviceURL=http://localhost:8080/opal2/services%2Ftestit

13) Got an execution complete message and clicked on the URL:
http://localhost:8080/opal-jobs/apptestit1397756530532282548322

14) Clicking there gives the following error message:

=====================

HTTP Status 404 - /opal-jobs/apptestit1397756530532282548322/

type Status report

message /opal-jobs/apptestit1397756530532282548322/

description The requested resource is not available.

Apache Tomcat/8.0.5

=====================

15) Investigated further, discover that my job was correcty saved to
$CATALINA_HOME/webapps/opal-jobs/apptestit1397756530532282548322

16) Discovered that the address
http://localhost:8080/opal-jobs/apptestit1397756762073676906347/stdout.txtdoes
in fact contain my output.

17) To see if this is just a web-interface problem, tried to access the
opal service programatically using your python client. It didn't download
the requested files. The url provided gave the same error when visited:
http://localhost:8080/opal-jobs/apptestit1397757356922-550301932/. But
http://localhost:8080/opal-jobs/apptestit1397757356922-550301932/stdout.txtdid
contain the results submitted programatically. Note that I do not have
this problem when I submit opal jobs programatically to services deployed
at nbcr-222.ucsd.edu.

So the problem seems to be with access, not with actually launching the
job. Can you tell me how best to fix this so I can begin developing and
testing my own Opal services locally?

Thanks for your help.
