How to make call to a package location in a code

[cpu2007]

Hi there

I have a lucene package which indexes files using the following command

java org.apache.lucene.demo.IndexFiles

Now I can use this on the command line but I would like to make some java code that automatically interacts with this code .

That line accepts two parameters in the following way:

java org.apache.lucene.demo.IndexFiles -docs "path where your corpus resides" -index "path

where you want the created index files to be saved"

How can I make some code in java so that I call that line and pass it the following parameters :

-docs accepts the path where I have the file with my data, do I have necessarily have to pass it the path or can I also load the data I want to process in a variable and pass that variable as a file to the indexFiles class?

If not, how can I run that class using java code ?

Thank you

Look at the Desktop and Runtime classes. You can call OS commands with methods in those classes.

Also google for using ProcessBuilder, there are loads of examples on how to use it.

There are also a few gotchas on using Process objects (as created by ProcessBuilder and Runtime.exec()) so I'd recommend you also read this article.
