We are using search&promote for seach on our site.
The usage is prettymuch inline with the OOTB searchpromote components in libs/cq/searchpromote path.
We receive an XML from s&p server.
We now are looking at having facets, I tried putting linklist facet on results page to get facets but it failed, so looking at logs and going through jar I noticed that facet component in its dialog calls a servlet (path+facetList.json) this servlet calls searchpromoteservice's get facetList method.
String facetList = this.searchpromote.getFacetList(memberId, accountNo);
JSONObject facets = new JSONObject(facetList);
but it then tries to convert string response as JSON object and fails since the URL http://sp10050b5b.guided.ss-omtrdc.net/design/sp_id=MyID-MyAccount&sp_fn=facets results xml rsponse.
Only changing this setting in search & promote to return json would suffice or I will have to make any other changes as well?
You should make sure that the XML that it is received is the AEM XML https://marketing.adobe.com/resources/help/en_US/snp/r_gsxmloutputforwem.html, not the normal XML. Also, it is not clear that which version of AEM your are sing . Actually is AEM code calling S&P, so the you should put the question in the AEM forum or contact support. you should not modified the templates in S&P to return JSON and you eed to re-write the AEM components to read them correctly, basically implement all S&P components.
Thanks & Regards
