In this article, we will explore the development of an IRIS client for consuming RESTful API services that have been developed to the OData API standard.

We will be exploring a number of built-in IRIS libraries for making HTTP requests, reading and writing to JSON payloads, and seeing how we can use them in combination to build a generic client adaptor for OData. We will also explore the new JSON adapter for deserializing JSON into persistent objects.

Read data from Excel

Hello,

I work as a contractor for the Department of Veterans Affairs. I want to read data from an Excel workbook. I searched posts here and saw Apache POI suggested. I believe Apache POI is not approved for use within VA. I also believe we should be able to run SQL query against Excel. Has anybody done such a thing or are there other ways to read data from Excel workbooks?

Thanks

I am using the Java Binding to connect a Java Middleware Application to Cache. Originally I was using a CacheListOfDataTypes (JAVATYPE = "java.lang.List") object to bring data back. I was tasked with encrypting the data using AES and I was using the AESCBCEncrypt function on the List elements (up to 20k characters for each element) to bring it back before concatenating it on the middleware. This almost worked. Like 95% of the characters were being decrypted correctly but some text was coming back garbled. I couldn't understand how this was happening.

Hi All,

So after finally getting cache to install (by enabling root user and disabling the gatekeeper) it tells me that it has started with one alert... that is "Private web server has not started after 5 seconds." - urgh!

Obviously i need access to the management portal to continue setup, I've done lots of googling but i cant find anything on this, does anyone have any ideas?

Many thanks,

Dan

A More Industrial-Looking Global Storage Scheme

In the first article in this series, we looked at the entity–attribute–value (EAV) model in relational databases, and took a look at the pros and cons of storing those entities, attributes and values in tables. We learned that, despite the benefits of this approach in terms of flexibility, there are some real disadvantages, in particular a basic mismatch between the logical structure of the data and its physical storage, which causes various difficulties.

I am trying to do package mapping in the %ALL NameSpace.

I create a new Package Mapping entry and select my database bu the "Package Name" combo box never populates the packages in this database so I cannot select it, see screenshot below, the "Package Name" list remains empty. There definately are packages in that database. Why is this happening? Did I miss a setting?
