Problem with dynamic configuration in PI 7.0 (SP 21)

[former_member84399]

We're trying to set a dynamically configurable parameter (UrlParam in plain http adapter) in a java mapping and when calling, via proxy, getting the following error returned<br />

<p />

<br />

&lt;?xml version="1.0" encoding="utf-8" ?&gt;<br />

- &lt;asx:abap xmlns:asx="http://www.sap.com/abapxml" version="1.0"&gt;<br />

&lt;/INTERNAL_SOURCE_POS&gt;<br />

&lt;/CX_ROOT&gt;<br />

&lt;ERRORTEXT /&gt;<br />

&lt;LANGUAGE /&gt;<br />

&lt;/CX_AI_SYSTEM_FAULT&gt;<br />

&lt;/cls:CX_AI_SYSTEM_FAULT&gt;<br />

&lt;/asx:heap&gt;<br />

&lt;/asx:abap&gt; <br />

The java code in the mapping is as follows:<br />

Looking at the call in SXMB_MONI there's no sign of the dynamic configuration stage anywhere but we are seeing the following in the response message:

<p />

<br />

&lt?xml version="1.0" encoding="UTF-8" standalone="yes" ?&gt;<br />

&lt;SAP:Retry>N&lt;/SAP:Retry&gt;<br />

&lt;/SAP:Error&gt;<br />

<br />

Please note, we have set this up on another PI system (7.0 sp 12) and it works as required.

Many thanks

You have just created a key, but you have to put a value also. Check online help for an example.

Something like key.put

Are you really using "myValueHere"? You have to use the constants which you also find in online help.

Hello , let me clarify:

- There's a graphical mapping which has a user defined function with the following code:

DynamicConfigurationKey dynKey =DynamicConfigurationKey.create(

"http://sap.com/xi/XI/System/HTTP",paramName);

DynamicConfiguration dynCon =(DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);

dynCon.put(dynKey, paramValue);

return paramValue;

- The above UDF has paramName set to UrlParamOne via a constant and paramValue set a per an element in the incoming structure.

- Incidentally, a Java mapping is then called (although not relevent) to clear the xml produced from the mapping. This is a requirement for our customer who don't want the HTTP body set. The code is as follows:

}

> Hello , let me clarify:

It does not clarify anything, when you post something totally different

Anyway, in online help are examples for dynamic configuration for all type of mappings.

You can also check:
