Running jar file : RangeError: Trying to access beyond buffer length #22

Closed lerouxrgd closed 4 years ago

Hi,

I tried to use the following java code : https://github.com/tcurdt/lzo-index/tree/master (complied jar file with maven)

I wanted to use it like this :

var JVM = require("node-jvm"); var jvm = new JVM(); jvm.setLogLevel(7); var entryPointClassName = jvm.loadJarFile("./lzo-index-0.1.jar"); jvm.setEntryPointClassName(entryPointClassName); jvm.on("exit", function(code) { process.exit(code); }); jvm.run(["file.lzo"]);

I got the following error :

DEBUG: loading ./lzo-index-0.1.jar@org/vafer/lzo/Main.class ...

/home/raru/dev/js/test/node_modules/node-jvm/libs/util/reader.js:0

Does the support for jar file depends on how you compile it ?

The main problem in class file parser.

Could you please send me this jar?
