Submission not occuring

Hi,

I'm having trouble getting my xform to submit properly. I'm a
beginner, so hopefully my mistake is something stupid and obvious.

I have Orbeon 3.6 on Tomcat 6 on Windows. I have my own webapp,
deployed seperately, with a static .xhtml in /xforms-jsp - all that's
working ok.

But the submissions aren't working. First I tried to submit to the
built-in eXist database in the way the bookcast example does, then I
gave up and made a simple servlet to accept the xml in a http post. I
can't get either to work.

My eXist submission (copied off bookcast example, but do I need to
create the eXists 'tw' collection first?):

<xforms:submission id="save-submission"
ref="instance('message-instance')"
action="/exist/rest/db/orbeon/tw/message.xml"
method="put"
replace="none">
<xforms:message ev:event="xforms-submit-error" level="modal"
value="event('body')"/>
<xforms:message ev:event="xforms-submit-done"
level="modal">Saved!</xforms:message>
</xforms:submission>

My servlet submission:

<xforms:submission id="save-submission"
ref="instance('message-instance')"
action="/TW/ReceiveMessageXML"
method="post"
replace="all">
<xforms:message ev:event="xforms-submit-error" level="modal"
value="event('body')"/>
<xforms:message ev:event="xforms-submit-done"
level="modal">Saved!</xforms:message>
</xforms:submission>

doPost method of servlet:

protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

ServletOutputStream out = response.getOutputStream();
ServletInputStream in = request.getInputStream();

byte[] buffer = new byte[1024];
int len = 1024;
int off = 0;
int result = 0;

response.setContentType("text/html");
out.print("<html><body><pre>");

while (result >= 0) {
result = in.read(buffer, off, len);
off += result;
out.write(buffer, off, result);
}

out.print("</pre></body></html>");
}
}

I've tried to enable Orbeon logging by uncommenting everything in
RESOURCES/config/log4j.xml, reploying Orbeon and restarting Tomcat -
but I can't find a log file. Where is it created?

I've tried using tcpmon as a proxy server, and I can see the http put
when I run the bookcast example, but not when running my xform. I
just get a DOMFocusIn, DOMActivate http post for the save button.
Perhaps this means Orbeon thinks my xml instance is not valid - but
there are no !s next to input fields, and the event('body') is null.
How would I check if this were the case?

Thanks,
Malcolm.

Re: Submission not occuring

I got Orbeon to perform my submissions by adding @validate="false".

1) So this means that Orbeon thinks my form data is invalid. There is no visual clue (ie no !s) that my instance is invalid, and I've triple checked it by eye using the Orbeon Forms XForms Instance Inspector - but can't see the problem. How would I go about debugging this to see exactly where the problem is?

2) When I perform my submission to my servlet, it does the POST, but my browser gets redirected to /opt/xforms-server-submit and there I get the error:

Path http://localhost:8000/TW/ReceiveMessageXML does not start with a "/" character

And ideas why I would be getting this? Or course it doesn't start with a "/"!? Is this due to POSTing to a servlet in a separate webapp?

3) When I perform my submission to eXist, it does the PUT, but I get an HTTP 403 Forbidden. This suggests that it's an authorisation problem. But the bookcast example provides no username/password and works, so why should my form?

An "invalid" instance for submission purposes is one with either or
both of:

* Actual invalid elements or attributes in the instance
* "Required but empty" elements or attributes

Did you enable XForms logging? You may see some interesting
information there:

http://www.orbeon.com/ops/doc/reference-xforms-2#xforms-logging

Try disabling optimized submissions in properties.xml:

<property as="xs:boolean" name="oxf.xforms.optimize-local-submission"
value="false"/>

By default, eXist supports a "guest" mode. Maybe your separately
deployed eXist (if that's what you are using) doesn't?

Yes, I've uncommented those bits from config/log4j.xml and restarted Tomcat. Now where is this logging supposed to spew out to?

<property as="xs:boolean" name="oxf.xforms.optimize-local-submission"
value="false"/>

Thanks - that works (after I fixed the deliberate error in my servlet ;-). What are the side effects of making this setting? I want all my submissions as optimised as possible!

I'm trying to use the eXist built-in with Orbeon. That's why I don't why the bookcast example works with no authentication, yet my xform doesn't.

That too is configured in log4j.xml. You can try the console appender
and / or the file appender.

What the "optimized" version does is, in some cases, skip the actual
HTTP step. But it seems that this can cause some issues.

It should though! Maybe you can use something like tcpmon to figure
out what's happening on the wire.

Thanks. I was an idiot. By default it logs using SingleFileAppender to ../logs/ops.log, which is relative to Tomcat directory. I was searching from Tomcat directory down, so didn't find it.

I used the logs to find the problem with my submission. I was using a * in the nodeset of a <xforms:bind> which was including more nodes than it should.

Does the XForms specification specify what should happen when the a node of an XML instance are in more than one <xforms:bind>?

Using tcpmon I can see the XML in the HTTP PUT. The reply is 403 Not authorised with the HTML for the standard Tomcat error page.

I don't get this error if I run my XForm in the Orbeon sandbox thing - only when running as a seperate webapp.

Is there further configuration I must do to allow my separate webapp to use the eXists database built in to Orbeon?

Thanks,
Malcolm.

Yes, as per 1.0/1.1 it should throw an exception. But Orbeon Forms
does not enforce this rule. There has been some debate recently in the
Forms Working Group as to whether we should change this in the future
anyway, as it clearly makes sense, for example to have multiple
constraints on a single node, expressed with multiple xforms:bind
statements. The question is how do the MIPs combine (easy for
validation, but the behavior of readonly, required, etc. must be
determined).

It really seems that eXist is expecting some credentials. Did you try
using xxforms:username and xxforms:password on xforms:submission?

Hi Gopikrishna

> how can i keep max length for this as iam giving xxforms:maxlength but it doesnt work for xforms:textarea

you could try to restrict the length of the content using a binding and
xpath:

constraint="string-length lt 71"

Info about the xpath string-length function:

At the moment, I don't think so.

The HTML <textarea> element doesn't support a maxlength attribute, I
believe, so you can't. HTML 5 will likely add this attribute. Does
anybody know if it is actually already supported in some browsers?
