Aq Adapter ( ESB ) and CLOB payload

Question

I have a AQ adapter which consists of the following payload :
CREATE OR REPLACE TYPE "XML_CLOB_TYPE" AS OBJECT
(XML CLOB
I've added an AQ adapter in ESB which enqueues messages to this specific queue. I've got a certain payload ( in XML format ) that I want to enqueue in this queue. When I add a routing rule to the routing service and create a XLST mapper I can only see XML as the target attribute. which is quite obvious as this is the defined type.
Is there an easy way to enqueue a full XML message into this CLOB? Or is the possibility to escape all the < and > signs in my xsl like this?
<xsl:template match="/">
<obj1:XML_CLOB_TYPE>
<XML>
&lt ; test &gt ;
<xsl:value-of select="/imp1:transacties/imp1:transactie/imp1:brokerid"/>
&lt ;/ test &gt ;
</XML>
</obj1:XML_CLOB_TYPE>
</xsl:template>
the above method works but is cumbersome and (IMHO) quite ugly.
anyone has a better working solution?
TIA

Hi Martin-
I am facing a similar issue. Here is the details, please let me know how you resolved it.
We have created an AQ in Oracle DB which will have the following message Structure:
CREATE OR REPLACE TYPE enqueue_payload AS OBJECT
( field1 VARCHAR2(100),
field2 VARCHAR2(100),
field3 DATE,
field4 VARCHAR2(100),
field5 NUMBER,
payload CLOB,
In the Payload field we are enqueing an XML message.
We have to use a OSB proxy service to dequeue the message from the AQ, transform it to another format and send to a SOA Composite.
We created a AQ Adapter in Jdeveloper 11g and imported the WSDL, XSD and .jca jca binding file into the OSB project. And configured the OSB proxy service using the WSDL imported.
However in OSB proxy service message flow when I try to create an XQUERY transformation, I see that the Payload field does not expose the structure of the XML message that is being enqueued. I even changed the message structure definition to have the payload field as XMLType. But it didn't help.
On analyzing the XSD created by AQ Adapter, I see that the payload is being defined as "string" in the XSD.
Inputs Needed
=========
1. How can we parse the payload field defined as CLOB/XMLType in OSB so that I can see the structure of the XML message it holds ?
2. Is there any in-built function in OSB to convert it to XML ?
3. Any other inputs in order to transform the XML message coming in the payload field as CLOB/XMLType
Please provide your inputs and I hope that I have clearly explained my use case.
Thanks in advance for your time and help!!
