ORACLE COM JAVAMAGAZINE MARCH APRIL 2017 07 letters to the editor Editor Andrew Binstock responds All told the responses were more than 75 percent in favor of inclusion of JavaScript on a regular basis Based on this well begin regular coverage of it in the next few issues In the meantime a JavaScript article that was scheduled long ago is included in this issue As we move forward well be careful to keep in mind the recommendation of reader William McKenzie who upon reassurance that JavaScript would not come to dominate the content kindly replied That sounds appropriate to me I love Java Magazine and dont want it to lose itself Blockchain Blockage I liked the article Blockchain Using Cryptocurrency with Java in the January February 2017 issue but on page 44 the call of the method Greeter deploy web3j credentials BigInteger ZERO new Utf8String is not complete because you need to set the gasLimit What is the value of the gasLimit when the gasPrice is set to zero Elton DePaula Author Conor Svensson responds Its best if you refer to the accompanying code in the GitHub repository You can see the correct values to use at this link If you have any further questions you can also join the web3j community on Gitter to get assistance Being Fair to Gradle Builds In his article on build tools The Design and Construction of Modern Build Tools in the January February 2017 issue Cédric Beust wrote With Gradle you need to manipulate multiple build gradle files that in turn refer to multiple settings gradle files The only way you would be referring to multiple settings gradle files is if youre working with multiple projects even multiple multimodule projects However each project whether a standalone project or a multimodule project only ever has a single settings gradle file In addition the text makes it seem like this new approach of Kobalt is the only one that makes it possible to define multiple projects in one build file This is also possible in Gradle and its quite common I certainly think its likely that Kotlin is going to be the main scripting language for Gradle Kobalt will likely contribute ideas for that but its important to be accurate and fair in comparisons of existing procedures David Michael Karr Author Cédric Beust responds You are correct that most projects usually have one settings gradle file but that file is pretty much the only way to have multiple modules Here is the typical way to do this from Gradles project itself Contact Us We welcome comments suggestions grumbles kudos article proposals and chocolate chip cookies All but the last two might be edited for publication If your note is private please indicate this in your message Please write to us at javamag_ us@ oracle com For other ways to reach us see the last page of this issue
