I have two local instances:
I'm using Java Gateway to talk to external system.
Both instances are using the same:
They are calling the same method with this java signature:
Hi! I am working in a java project (Spring Boot+ Maven + Hibernate) using jpa/hibernate to manage the persistance with the IRIS database from the Docker image (store/intersystems/iris:2019.2.0.107.0-community) and I've found an issue using the IRIS instance, when I define tables with relationships OneToMany, ManyToOne or ManyToMany and I try to fetch all the rows of the tables using the default method findAll (JpaRepository implements that method to get all the rows by default) the query automatically exceeds the limit of licenses availables.
Good morning!
I am developing a Java project (Spring Boot + Maven + Hibernate) but I've a big issue when I try to define the Hibernate Dialect org.hibernate.dialect.InterSystemsIRISDialect... that dialect is neither in the Hibernate library nor in the IRISDriver class com.intersystems.jdbc
How should I define the IRISDialect in my project?
Thank you in advance!
In my production I receive an XLFO stream and I would like to pass that to the FOP pdf rendering engine to produce pdf files .So far in my research that can be achieved through ZEN .I would like to create an operation that will take advantage of that and be able to pass my XLFO stream to the operation and create pdf files I found something similar here but for some reasons I get errors like below if any one understands what they mean please advice or someone who had to do something sim
Hi everyone,
Im new in cache, i came from Java and im missing some features that i couldn't find in the documentation, I hope you can help me with this questions.
Just a brief introducction:
- Im in a project with old cache version, so saddly i can't use Eclipse + Atelier, so im using Studio.
- Currently im in a project with persistent classes, we want to turn apart the globals and focus on tables.

Hi All,
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:
public JSONValidator(char[] jsonStream, char[] schemaStream) { ... }
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.
I successfully got everything in this guide to work: https://community.intersystems.com/post/ensemble-rabbitmq-java-client-qu...
I am now using the information I gained from this guide along side with this guide:

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:
Hi
Totally new to IRIS and Cache.
Trying to evaluate it and work out how we could use it.
As a standard application database. Object or relational etc. does not matter.
Issue is ObjectScript.
So:
1) Can we develop, maintain and use an IRIS database and never use ObjectScript i.e. use only Java, Python, C++ interfaces etc. (exactly which one does not matter)? Would that make designing and using the IRIS database more prone to inefficiency and error?
Hi,
I ran into the Issue https://hibernate.atlassian.net/browse/HHH-10620. The workaround described at https://community.intersystems.com/post/support-java-hibernate-5 worked for me. I'm using Hibernate Version 5.3.2.Final.
Working on implementation FHIR to my project, I found interesting project HAPI-FHIR, which could help me to quickly launch my FHIR api server with InterSystems Caché as a storage, because this projects uses Hibernate to connect to database, as an example they use DerbyDB. I tried to change settings to use InterSystems Caché, but unfortunately it does not work and throw some errors inside HIbernate. As I found in Caché documentation, I have not some many options, I just have to set Cache dialect, and set database url.
Hello,
Currently, I'm working with a Java Gateway, and I have the following problem. When importing a class into IRIS, which uses methods from a generic class, I can not find the general methods I need. I'm talking about the test2 method from the class test. How can I import the java method that returns a generic?
I want to call java method and return $lb structure from it.
JDBC jar seems to contain relevant class - com.intersys.jdbc.CacheListBuilder, but so far I only managed to return a string that looks like a list.
Here's my java code:
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.
How can I load a dll at run time using COS?
Hello Global masters!
I developed Web with Spring framework (JAVA, Jdbc Cache) and I wrote SQL when I made it.
And Window program with VB6, Cache Object and VisM.
Is there a significant performance gap? SQL and Cache Object?
same function, same computer performance just different Java and VB6.
Thank you.

Hi,
i have today
- update from Ensemble 2016.1.0.656.0 to 2017.2.1.801.0
- Java JDK 8 (U161) [latest Version]
- Eclipse (JavaScript & WebDev) Release 4.7.3
- Atelier 1.1 plugin (from Marketplace)
- Migrate a small testing Project
Trying "Debug":
- Debug Configurations ...
- "Atelier Application Attach" -> "New"
- Select Server, Choosing the process i want, "Apply", "Debug"
Error:
I'm having a lot of trouble figuring out how to properly map List collection types. I can't change the schema at all, and I don't have the ability to change the way they are stored from the serialized form to the Array projection. I'm also pretty locked into using JPA for Java interoperability, as I'd like to be able to change out the backing database arbitrarily.
Problems encountered with Java Gateway
I am writing a framework for use on the Java Gateway. The role of the framework is:
1. Import the framework jar file into ensemble studio (test completed);
2. In the framework jar, handle the related functions of the remaining jar files (the rest of the jar files are written by colleagues).
The general idea is as follows:
Send: Ensemble Java Gateway -> Framework Jar -> Plugin Jar (colleagues write, processing data).
Returns: Plugin Jar (processed return data) ->Framework Jar->Ensemble Java Gateway.
I have a simple app which tries to establish a connection with a Cache database instance via Global API for Java:
import com.intersys.globals.Connection;
import com.intersys.globals.ConnectionContext;
public class Assignment {
public static void main(String[] args) {
Connection connection = ConnectionContext.getConnection();
connection.connect("SAMPLES", "_SYSTEM", "SYS");
}
}

Hi-
I have searched through documentation, etc and see many mentions of using Ensemble / Health Connect along with the Java Gateway to interface with JMS Queues, but see no specific documentation on how to do this.
Does anyone have any information, or a concise example of using the Java Gateway to allow Ensemble / Health Connect to be able to place messages and retrieve messages from a JMS Queue?
Thanks
Hello I'm Minsu
I want to develop web program like community with Spring Framework and Caché. but I have experience only with MySQL.
A. Can I use Caché with Spring Framework?
B. If I can, How?
Thank you guys.
I ran the below query in three different modes. Coordinated Universal Time is 5 hours ahead of Eastern Time so there is difference in value from column 1 and column 2 in ODBC, Display mode, but not in Logical Mode. By default the query executes in ODBC mode when we query the data from outside world(via ODBC connection).
I don't know why query 2 and query 3 outputs different from query 1.
Query 1. Ran in Logical mode, DATEPART() took in memory stored timestamp data(stored in UTC)
I defined the variables in Cache, as follows:
Property Content As% Stream.GlobalCharacter [Required, SqlColumnNumber = 3, SqlFieldName = B_Content];
And then use the SQL statement to add:
insert into table_name (B_Content) values ('very long string');
But the error:
Trying to connect Ensemble to RabbitMQ following this article I'm using Java Gateway and encountered the following problem - in all my calls I need to pass connection object, which is always the same but it takes a long time to create. Here's java code:
Hi all-
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 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.
Thanks

Hi people,
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...
Hi
Do any of you Java Ensemble enthusiasts have a simple example of an Ensemble Production and .Jar they would be willing to share with me.
