HelloFromJava.java in code block 2 contains the code for the HelloFromJava class. In line 6, javacall executes the helloJavaWork method of the class HelloFromJava, which is in the JAR file hellojavawork.jar. Javacall HelloFromJava helloJavaWork, jar(hellojavawork.jar) Code block 1 contains the code for myhellojava.ado that calls a Java plugin that makes Stata display “Hello from Java”. See Programming an estimation command in Stata: A map to posted entries for a map to all the posts in this series.īefore I do any computations, I illustrate how to write and to compile a Java plugin that communicates with Stata. This is the 32nd post in the series Programming an estimation command in Stata. I do not assume that you are familiar with the material in those posts, and much of that material is repeated here. The differences are due to the plugin code being in Java instead of C or C++. Now we have only designed this calculator, now we will implement it. This post is analogous to Programming an estimation command in Stata: Writing a C plugin and to Programming an estimation command in Stata: Writing a C++ plugin. Step 4: Activate the calculator with JavaScript. The downloaded csv file is named generic/ automatically 'download.csv' and I would like to change the name of the csv, so that it gets downloaded and named with one for the form field data, example: txtPOC1. In this post, I write a plugin in Java that implements the calculations performed by mymean_work() in mymean11.ado, discussed in Programming an estimation command in Stata: Preparing to write a plugin, and I assume that you are familiar with that material. The form works and I can download the form as csv to the local download folder. This technique is known as writing a plugin or as writing a dynamic-link library (DLL) for Stata. This post is the fourth in a series that illustrates how to plug code written in another language (like C, C++, or Java) into Stata.
