Is there a best practice to set the memory options (classic xms and xmx) on the JavaGw service in the production?
What can be recommended?
Like specifying 1024M for xmx is for a single process? that process can't grow beyond that value right? what happen if the process reach the memory limit?
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 migration my web application of Cache 2013 to Cache 2016, in Cache 2013 I have a integration with a Java aplication using Java Gateway mapping proxy classes and consuming a method that param is a object, and it works perfectly.
But in Cache 2016 this integration don't work, I send the param as object but Cache send as String with the ref of object...
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:
I'm working on developing Productions with java. The sample project has several intersystems jar files:
-- intersystems-enslib-jms-3.1.0.jar
-- intersystems-gateway-3.1.0.jar
-- intersystems-jdbc-3.1.0.jar
-- intersystems-spark-1.0.0.jar
-- intersystems-uima-1.0.0.jar
-- intersystems-utils-3.1.0.jar
-- intersystems-xep-3.1.0.jar
I have the jar files, but where can I find them for download? Are they available on a maven repository somewhere?
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...
I know there are numerous Java libraries available to scan a PDF meta data, but is there a way to scan a PDF using native cache object script? We are looking to take a PDF from an external vendor, scan for meta data, create the HL7 message, and embed the PDF within the HL7 message.
I am using java gateway imported/proxy classes and JG business service. I need to load a dll at run time.
I use System.loadLibrary/System.load when in java. I’ve tried $ZF(-3,” C:\Windows\System32\pteidlibj.dll”) and $ZF(-4,1,"C:\Windows\System32\pteidlibj.dll") but I’m getting <DYNAMIC LIBRARY LOAD> error.
We used to have this Java applet in our CSP page to "print all" and "download all" PDF medical reports. We want this applet so that the user won't have to open each PDF in the browser just to print it.
But now most browsers do not support Java applets anymore due to security concerns, so that Java application is down. We tried to migrate to Java Web Start but don't know how to invoke the JNLP file from the CSP page. I am new to Cache so any help would be greatly appreciated.
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.
Hello. I'm having problems migrating a java application that is running with cache 2018 to Iris The application uses json generated by the cache to receive it as a string in java.
For example, I have two timestamp values ('2024-04-01 10:00:00', '2024-04-01 11:30:30'). I would like to find the difference between these two timestamps, and I need the result in hours:minutes:seconds (hh:mm:ss) format.
Expected Output: 01:30:30
Note: I need an SQL query command. I should not use ClassMethod, Function, or Stored Procedure.

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 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.
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:
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:
