big amount of data

Dmitry Belous
Hi

I created a form with big number of fields.
I load form data by following line:

<xforms:send submission="get-patient-submission" ev:event="xforms-ready"/>

Form load successfully.

I have a button on form that do some changes and then reload form data.
I use following code:

<xforms:group>
<xforms:action ev:event="DOMActivate">
<xforms:send submission="add-emergency-contact-submission" />
<xforms:send submission="get-patient-submission"/>
</xforms:action>
<xforms:trigger appearance="minimal" ref=".">
<xforms:label>
Add
</xforms:label>
</xforms:trigger>
</xforms:group>

But when "get-patient-submission" return big amount of data I got "socket write error" exception.

Any ideas how can I solve this.

This is log:

Hi Dmitry,

I have the same problem.
Did you manage to fix this problem?

If so...how?

Raoul,

Orbeon Forms tries to use persistent connections when talking to your
service. This is done to avoid the cost of establishing a new HTTP
connection for every call (which besides improving performance also
solves other problems on some platforms), and this might explain why
you see a difference between the first and the second call.

Who is responding to that HTTP call? Is it Tomcat, or Apache, or some
other piece of software? Would you be able to trace the HTTP calls to
see exactly what goes over the wire?

Alex

Re: Re: big amount of data

Hi Alex,

Thanks for your reply.

I hope this is the data you asked for.
The first GET loads the big amount of data.
After the data is loaded I trigger an another load of the data, but then the socketexception occurs.

I hope you have a solution for my problem.

Raoul

My understanding is that the error happens between Orbeon Forms and
the service you are calling. Here you have the HTTP connections
between the browser and Orbeon Forms. So we would need to look at the
same thing, but between Orbeon Forms and your service.

Also, what technology is your service implemented in? What is
answering the HTTP queries?

Re: Re: Re: big amount of data

Raoul
Alex,

I once more traced the http requests.
After the first load of the data there is no more http communication between Orbeon Forms and
the service I'm calling. I think that is where the socket exception occurs. When I trigger Orbeon Forms to load the data for the second time the socketexception occurs...so the request is never sent to the service. The service that I call is a JBoss rest easy webservice.

This is how my service looks like:

  @GET
  @Produces("text/xml")
  @Path("/prioreducationsbyidpreselect/{id_preselect}")
  @XmlHeader("<?xml type='text/xml' encoding='UTF-8'?>")
  public String getPriorEducationsByIdPreSelect(@PathParam("id_preselect") String id)
  {
    log.info("getPriorEducationsByIdPreSelect()");
    return retrieve("SELECT_PRIOR_EDUCATIONS_BY_PRESELECT", new String[] { id });
  }

Can you see if the TCP/IP connection is closed after the first
request? Could it be possible that the server closes the connection,
and that somehow Orbeon Forms (or rather the HTTPClient code we use)
doesn't know about it, and fails when it tries to send the next query?

You could try to:

* See if in JBoss there is a way to enable the support for persistent
connections, if this is not enabled by default.
* Disable the support for persistent connections in Orbeon Forms by
changing the code: in HTTPURLConnection, instead of creating a
MultiThreadedHttpConnectionManager, create a
SimpleHttpConnectionManager(true) – the true is to tell the HTTPClient
to always close the connection.

Re: Re: Re: Re: big amount of data

Raoul
Alex,

I tried to disable the support for persistent connections in Orbeon Forms by
changing the code in HTTPURLConnection, but now I get a NoSuchMethod exception when I try to load my page. (see below)

I don't know why this is happening.
First I downloaded the source code at http://github.com/orbeon/orbeon-forms/tree/master
Then I modified the file, executed the orbeon-war ant script and deployed the new war file.
I also checked if the new HTTPURLConnection class file is part of the new war file....and it is.

Do you know why I get this behaviour?

Can you see if the TCP/IP connection is closed after the first
request? Could it be possible that the server closes the connection,
and that somehow Orbeon Forms (or rather the HTTPClient code we use)
doesn't know about it, and fails when it tries to send the next query?

You could try to:

* See if in JBoss there is a way to enable the support for persistent
connections, if this is not enabled by default.
* Disable the support for persistent connections in Orbeon Forms by
changing the code: in HTTPURLConnection, instead of creating a
MultiThreadedHttpConnectionManager, create a
SimpleHttpConnectionManager(true) – the true is to tell the HTTPClient
to always close the connection.

Raoul,

Not sure why that's not working. You might have to use a debugger to
figure this out better.
