Web traffic for the WSRP4J demo

pencil icon, that"s clickable to start editing the post
Work in slow progress Following the README with the WSRP4J dist I succeded in getting the demo running and heres a dump of the web traffic it generates as captured with the tcpmon tool. The traffic is between the wsrp4j proxy portlet and the wsrp4j-producer (forwarding the jsr168 testportlet that comes with wsrp4j). The portlet page that these (identical) portlets end up in looks like.

What do you have to offer

The first thing the proxyportlet does it to query the wsrp4j-producer about what portlets are available (done with axis 1.4 which the wsrp4j proxyportlet uses):
POST /wsrp4j-producer/services/WSRPServiceDescriptionService HTTP/1.0
Content-Type: text/xml; charset=utf-8
Accept: application/soap+xml, application/dime, multipart/related, text/*
User-Agent: Axis/1.4
Host: localhost:9101
Cache-Control: no-cache
Pragma: no-cache
SOAPAction: "urn:oasis:names:tc:wsrp:v1:getServiceDescription"
Content-Length: 386

    </getServiceDescription>

</soapenv:Envelope>

and the answer is

</soapenv:Envelope>


which is kind of an no-answer since it just indicates the it requires registration prior to any thing (requiresRegistration), and that it requires that cookies are initialized per group (requiresInitCookie) more about that later.

All right I'll register
Since it requires registration there's only one thing to do:
POST /wsrp4j-producer/services/WSRPRegistrationService HTTP/1.0
Content-Type: text/xml; charset=utf-8
Accept: application/soap+xml, application/dime, multipart/related, text/*
User-Agent: Axis/1.4

<soapenv:Envelope

  xmlns:xsd="http://www.w3.org/2001/XMLSchema"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <soapenv:Body>
    <register xmlns="urn:oasis:names:tc:wsrp:v1:types">
      <consumerName>WSRP4J Proxy Portlet</consumerName>
      <consumerAgent>WSRP4J Proxy Portlet</consumerAgent>
      <methodGetSupported>false</methodGetSupported>
    </register>
  </soapenv:Body>
</soapenv:Envelope>
and the producer accepts with:
HTTP/1.1 200 OK
Server: Apache-Coyote/1.1
Content-Type: text/xml;charset=utf-8
Date: Tue, 06 Mar 2007 09:25:03 GMT

    </registerResponse>
  </soapenv:Body>
</soapenv:Envelope>
so the registrationHandle is 0:0:0:0:0:0:0:1_1173173104036_0.

Okay now show me what you offer After having registred it's now possible to actually get the serviceDescription:
POST /wsrp4j-producer/services/WSRPServiceDescriptionService HTTP/1.0
Content-Type: text/xml; charset=utf-8
Accept: application/soap+xml, application/dime, multipart/related, text/*

      </registrationContext>
    </getServiceDescription>
  </soapenv:Body>
</soapenv:Envelope>
and here goes the answer which is quite verbose since it contains a complete description of the portlet/service. One annoyiance is all the unnessesary xsi:type the Axis 1.* produces which I've never been able to remove not even with sendXsiTypes.

So there two portlets availeble and they are identified by:

  • wsrp4j-testportlet.WSRP4JTestPortletA
  • wsrp4j-testportlet.WSRP4JTestPortletB

and the are actually the same portlet, that is portlet code but exposed twice to show of som IPC (Inter Portlet Communication) within a portlet group (portletapplication).

I don't understand why it's done this way since it's all webservice and not (legacy) browsers, so all clients will be WSRP aware, but I guess the spec writers wanted to stick with known protocols where possible, so the session handling between the consumer and producer uses normal HTTP cookies. Now discovery and initialization is done and the markup can be exchanged.

Give the markup for the portlet

and the same for the other portlet (ending with B).

please send the image

The portlet has an image resource that's fetched and cached for the second portlet. The request is a simple HTTP GET request (without a body)

GET /wsrp4j-testportlet/images/project-logo.jpg HTTP/1.1
User-Agent: Java/1.5.0_10
Host: localhost:9101
Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
Connection: keep-alive


and the answer is the jpeg image in binary so I'll not show that:

HTTP/1.1 200 OK
Server: Apache-Coyote/1.1
ETag: W/"12241-1171550282000"

and that completes the portlet page that the user sees.

I got the following errors when compile pluto-1.0.1 by maven-1.0.2:

Line...... 31
Column.... 46
The build cannot continue because of the following unsatisfied dependencies:

dom4j-1.4-dev-8.jar
commons-jelly-20030902.160215.jar
commons-jelly-tags-jsl-20030211.143151.jar
commons-jelly-tags-log-20030211.142821.jar
commons-jelly-tags-velocity-20030303.205659.jar
commons-jelly-tags-xml-20040613.030723.jar (try downloading from http://jakarta.
apache.org/commons/jelly/libs/xml/)
commons-logging-1.0.3.jar
velocity-1.4-dev.jar
xml-apis-1.0.b2.jar

Do you know how to fix it?

Hi Henry

I haven't looked at WSRP4J for quite some time, so my knowledge is a bit distant. I'm sorry but I don't know the solution for the problem you are experiencing. I can't even remember how I did that install and maybe there aren't any full binaries (so I somehow managed to get a successfull build). I never got around to understanding marven (ant does pretty fine for my own work, which is on another scale) but I do recall some problems related to missing jars in a repository, but it's kin of a wild guess and it doesn't have to be related to this.
I can also see that you've allready tried the maillist for wsrp4j. My best bet is to hope for someone to answer to the list or that you try a more recent build.

Best regards
Brian
