When using "IDENTITY" as my primary key, I can select the last inserted ID with 

SELECT LAST_IDENTITY() FROM %TSQL_sys.snf;

Actually this is how Hibernate + Iris' Driver acquires the inserted ID when mapping with

@GeneratedValue(strategy = GenerationType.IDENTITY)

 

Now, considering that I am using the type "SERIAL" as my primary key instead, how can I get the last inserted ID?

Note that with "SERIAL" I can forcefully insert any value for this ID, from which Iris will continue generating values...

0 1 50

Consider a Natural Key with an Identity (Serial) field.

I cannot seem to acquire the generated value after persisting my entity. That is, the returned entity by Spring Data's "save" does not have the generated value.

The value is generated by the database, and I can query it after repository.save(entity).

I have done some testing and created a Github repo with it...

Hello,

We would need some help.

We have a Java project in Eclipse which uses two external libraries, which are referenced as a maven pom.xml dependency.

We created a JAR with all the dependencies included.

We have used the Java Gateway Wizard as follows:

In the image you could see that we have chosen the project's jar, written IP and PORT of Gateway and written all external dependencies' server path separated with semicolons.

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.

Web Sockets

Hi

I am working on a project that will interact with some software called ROS (Robot Operating System). One of the development challenges we have is as follows:

 

ROS uses web sockets... So one connect with ws://localhost:9090 to the web socket server.  It starts off as http, but then "upgrades" to web socket.  It then keeps open this "tunnel" for bi-directional communication..

 

I need something like a HTTP Outbound adapter, but the Web Socket version of it...

Does anyone have any experience in this area?

Hello everybody,

My question would be, how is the recommended way to access Windows shares, also in view of future demads. Of course, I'm also happy about an explanation or code snippet of how the library, which is mentioned in the following , can be used under cache.

The classic jcifs library is easy to use, also with Cache, but as microsoft ceases support for smb1, we are currently looking for alternatives. jcifs-ng is such a library, which we took a closer look at. In java code a jcifs-ng file operation looks like this:

Hello community,

I'm new to Objectscript and Intersystems development. I've read documentation and some examples and succeded to import my Java class  file into HealthShare using the Java Gateway Service. To import my class i tryed both methods (Wizard, or scripting) with success.

Everything works great, i see my imported class inside the namespace, and i can call the methods.

I am under the impression that inside HealthShare you can Services, Processes, and Operations. The service takes incoming data, the processes can process that data, and then the operations can send that data out.

 

I am curious if anyone has any experience, guides, or advice on how I can send data to a service using a Java application. I intend for the data to be in XML format. I am also curious if I succeed at picking up the data in the service, how I send the data back to the Java application using an Operation.
