Java is a general-purpose computer-programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible.

Hi everyone, i'm using a render server to make pdf output with zen report and everything was fine till recently i've been getting this error message and i have no idea what it means, i'd be very thankfull if someone could help or got into the same situation.

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.
Any news about JDBC driver and Hibernate dialect on a public java repository, like mvnrepository? Today I need to download the jdbc driver and hibernate jar, add as an external resource on my maven config file to works.
A new Health Connect customer has a few experienced Java folks on their interface team. As they get more into Health Connect and learn Caché ObjectScript they thought it would be useful to have a list of common Java statements with an equivalent statement in ObjectScript. They mentioned string manipulation as an example, but would be interested in other areas as well.
This seems like something that is probably already floating around somewhere. Does anyone have something like this or other "COS jumpstart for Java devs" materials?
I'm trying to create a simple wrapper class around a JSON schema validator library, written in Java, and calling this functionality through the Java Gateway of IRIS 2019.1.
My Java wrapper class has a constructor like this:

I am trying to write a message to a Kafta cluster programmatically (i.e. not in Ensemble or using a Production) using %External.Messaging. I am consistently getting a 'topic not found error' even though I have created the topic on the cluster. I dug into the client I created an when accessing the property KaftaClient.jclient.gateway I get the following output:
I'm using Caché JDBC driver to store, retrieve and some other operations. I have another question, "Is there any possible to execute the cache commands using JAVA".
My developers are reporting many more NullPointerException errors when using Atelier then normal lately. This happens 'randomly' when moving about Eclipse. Anyone know what can cause this? One or two during a work session was normal but it's getting in the way of work.
In the purpose of my work, I have to implement a code that will communicate with a restful server coded in JAVA.
To fulfill my task, they gave me the link to the restful server + a certificate to use + the class that's going to be sent back + the names of 2 functions:
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.
Hi folks. I'm having trouble using the native iris API in an environment running wildfly 16. Here's a piece of my java class and stackTrack, I'm using jdk 8.
Hi.... I am trying to execute legacy routines from Cache 2018, into new environment with Iris 2021. I use new JDBC driver to make this connection, and change my java code to execute this legacy routines. But I get this write error: <REMOTE EXECUTE INVALID WRITE> I changed the mnemonic routine to populate object and return this object to java. And the java class convert this object to json. This is my simple classes used for this process, just to exemplification:
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.
