Using JSON to create Regions Dynamically
I’m creating regions dynamically using JSON… at least that’s the goal. The JSONFormatter blows up when trying to convert the JSON fragment below to a PDXInstance in preparation to be read by Region Attributes. I am referring to the AbstractBaseController>convert(String son) method. Does the json fragment need to be in an idiosyncratic format before being converted to PDX?
INFO: com.gemstone.gemfire.pdx.JSONFormatterException: Could not parse JSON document
protected PdxInstance convert(final String json){
try{
return (StringUtils.hasText(json) ? JSONFormatter.fromJSON(json) : null);
}catch(JSONFormatterException jpe){
throw new MalformedJsonException("Json doc specified is either not supported or invalid!", jpe);
}
}
{
server: {
dataPolicy: "PERSISTENT_PARTITION",
partitionAttributes: {
redundantCopies: 1
},
diskStoreName: "gemfire-store",
indexUpdateType: "synchronous",
//diskSynchronous: true,
statisticsEnabled: true,
"evictionAttributes": {
"lruHeapPercentage": {
"action": "overflow-to-disk"
}
}
},
client: {
type: "PROXY",
poolName: "publisher"
}
}

Thanks. I'm generating regions dynamically now like a madman.

Wes,
That doesn’t look like valid json to me…try http://jsonlint.com.
