Continuations in Java

From: "andrew cooke" <andrew@...>

Date: Sun, 14 Jan 2007 20:50:01 -0300 (CLST)

Commons Javaflow uses byte-code enhancement - either statically during
build, or dynamically using a classloader -
http://jakarta.apache.org/commons/sandbox/javaflow/tutorial.html

Rife is a full stack web app framework that uses continuations -
http://rifers.org/ (and has a bunch of other interesting things including
metaprogramming).  I can't find much detail on how they're implemented,
though - http://rifers.org/wiki/display/RIFECNT/Home

Javaflow Download

From: "andrew cooke" <andrew@...>

Date: Sat, 10 Feb 2007 23:32:46 -0300 (CLST)

I've had problems finding this a couple of times.  The SVN is at
http://svn.apache.org/repos/asf/jakarta/commons/sandbox/javaflow/

Building Javaflow

From: "andrew cooke" <andrew@...>

Date: Mon, 12 Feb 2007 21:32:19 -0300 (CLST)

I'm sure this can't be the simplest way, but here's what worked for me:

The following gets all the source:
 svn co http://svn.apache.org/repos/asf/jakarta/commons/trunks-proper/
  jakarta/commons/trunks-proper
 svn co http://svn.apache.org/repos/asf/jakarta/commons/trunks-sandbox/
  jakarta/commons/trunks-sandbox
That should all be on two lines, there's a space after "trunks-[...]/",
and you need to accept a certificate.

Then cd to jakarta/commons and
 cp trunks-proper/commons-parent/pom.xml .

Then cd to trunks-sandbox/javavflow and do a normal maven 2 build.

Deploying Javaflow

From: "andrew cooke" <andrew@...>

Date: Sun, 25 Feb 2007 21:05:10 -0300 (CLST)

To link to this it needs to be in a repository.  So I am going to use
Http:77www.acooke.org/m2 as a remote repository.

To deploy there I needed the following in ~/.m2/settings.xml:
<settings>
  <servers>
    <server>
      <username>acooke</username>
      <password>xxxxxxxxxxx</password>
      <id>acooke.org</id>
    </server>
  </servers>
</settings>

I had to make the directory on my server (/www/acooke/docs/m2).

Then I had to deploy the jar:
mvn -e deploy:deploy-file \
  -Durl=sftp://www.acooke.org/www/acooke/docs/m2 \
  -DrepositoryId=acooke.org \
  -Dfile=javaflow-1.0-SNAPSHOT.jar \
  -DgroupId=acooke-commons \
  -DartifactId=javaflow \
  -Dversion=1.0-SNAPSHOT \
  -Dpackaging=jar

Note that the groupId is acooke-commons and not org.apache.commons.  This
makes the deployed file logically distinct from the file I built in my own
local repository.  This decouples javaflow from the dependencies used by
the commons project (so I don't need to deploy the parent package etc).

In POrqi's pom I then add

    <dependency>
      <groupId>acooke-commons</groupId>
      <artifactId>javaflow</artifactId>
      <version>1.0-SNAPSHOT</version>
    </dependency>

and

  <repositories>
    <repository>
      <id>acooke.org</id>
      <url>http://www.acooke.org/m2</url>
    </repository>
  </repositories>

(I have done this before, but my reference notes were on my work machine....)
