WSO2數據服務服務器REST配置

Question

首先發布到SO，希望我能理解。 :-)

而且，新WSO2DSS ...

我想配置WSO2DSS揭露像REST服務，例如：

http://localhost/svcendpoint/products 
http://localhost/svcendpoint/products/computer 
http://localhost/svcendpoint/products/computer/disks 

其中每個URL返回一個更精緻的列表。我已經建立了三個查詢/操作/資源，但是我沒有得到預期的結果。

我得到第一個列表，第二個Axis2「字符串索引超出範圍」異常，第三個列表。

我不確定這是我，一個錯誤還是錯誤的方法。任何幫助，將不勝感激。

這裏是.dbs文件（我可以包括異常堆棧跟蹤它是否將是有益的）：

您需要調用的服務如下圖所示

http://localhost:9763/services/SERVIVENAME.HTTPEndpoint/RESOURCEPATH/ 

例如

http://localhost:9763/services/MyDataSource.HTTPEndpoint/category/computer
