How to Process data coming back from Java Delegation Processor

Hello all,

I'm new to Orbeon and XForms and had a relatively simple questions.

1. I have a form where I collection a username field.
2. A submit button sends the username to pipeline where the field is extracted.
3. The username is passed to a Java POJO where it is checked against LDAP to see if it exists.
4. If the username exists, a message is displayed to the user.

I've got 1-3 working. Now that I have the output in the pipeline, how do I pass it to the xform. Here's the pipeline...

<p:param type="input" name="instance"/>
<p:param type="output" name="data"/>


<p:processor name="oxf:xslt">
<p:input name="config">
    <xsl:stylesheet version=" 2.0">
        <xsl:template match="/">
            <delegation:execute service="my-service" operation="checkUsername">
            <param1 xsi:type="xs:string">
                <xsl:value-of select="/person/credentials/username"/>
            </param1>
            </delegation:execute>
        </xsl:template>
    </xsl:stylesheet>
</p:input>

<p:input name="data" href="#instance" debug="false"/>
<p:output name="data" id="username"/>
</p:processor>


<p:processor name="oxf:delegation">
    <p:input name="interface">
        <config>
            <service id="my-service" type="javabean" class="com.captechventures.sitc.foodstamps.test.XPLTest "/>
        </config>
    </p:input>

    <p:input name="call" href="#username" />
    <p:output name="data" id="username-count" />
</p:processor>

    <p:processor name="oxf:identity">
                <p:input name="data" href="#username-count"/>
                <p:output name="data" ref="data"/>
    </p:processor>

Thanks for your help!

Re: How to Process data coming back from Java Delegation Processor

Waseem,

Does your submission element have the replace attribute "all" or

"instance" ? You probably want to use instance. The LDAP query

will run in the background and when completed, any xforms elements

that are bound to that instance data will be updated for you by

the engine.

Or, You can use <xforms:trigger> and <xforms:submit> together:

<xforms:trigger>

<xforms:action>

<xforms:send submission="my-sub"/>

<xforms:toggle case="login-view"/>

</xforms:action>

</xforms:trigger>

If your submission uses replace="all" then the page will

be re-rendered and the instance is available as the page-flow

parameter in various ways:

<xforms:instance id="login-data" src="input:instance"/>

Cheers,

Hank
