Launching browser from java reuired download

There are multiple ways to download a file using Java code. Here are just a few ways of how you can accomplish the task:. The most easily available and a basic package available for downloading a file from internet using Java code is the Java IO package. Here we will be using the BufferedInputStream and the URL classes to open and read a file on a given address to a file on our local system. The reason we use the BufferedInputStream class instead of the InputStream is its buffering ability that gives our code a performance boost.

Before we dive deeper into the coding aspect let's take an overview of the classes and the individual functions we will be using in the process. The java. URL class in Java is a built-in library that offers multiple methods to access and manipulate data on the internet. In this case, we will be using the openStream function of the URL class. The method signature for the openStream function is:. The openStream function works on an object of the URL class.

The URL class opens up a connection to the given URL and the openStream method returns an input stream which is used to read data from the connection. These classes are used for reading from a file and writing to it, respectively.

The contents are read as bytes and copied to a file in the local directory using the FileOutputStream. To lower the number of lines of code we can use the Files class available from Java 7.

The Files class contains methods that read all the bytes at once and then copies it into another file. Here is how you can use it:. I have below version of chrome browser installed on my system. Remember this is just for reference. These versions will be changed with time. So just to follow the above process and download the correct version of chromedriver. Just click on the link and select as per your operating system and click on that.

It will start downloading. It is a zipped file that you need to unzip. After unzip you will get a chromedriver. For Mac and Linux there will be no extension as they follow permission-based capability to identify an executable file.

Note:- You can rename this file whatever you want. There are no restrictions that you can not change its name. Many beginners get confuse on this.

You just need to use the changed name in your program. Before launching a Chrome browser you need to let WebDriver know explicitly the location of chromedriver executable file. As of now, we will add the path of chromedriver as a system property.

Once you have the jnlp file, then you can execute it using the following command:. You must be logged in to post a comment. Primary Menu Home About. Search Search for:. In my case, while executing the step 1 from the previous workflow I had the following error: I was pretty sure that the JRE is correctly installed but because of some obscure reason the browser do not recognize that the JRE is present. I used the original BrowserLauncher class successfully in a multi-platform Java application which ran locally with a web browser interface in the early s.

If that license is unacceptable, look for a copy of the original BrowserLauncher which has a very liberal license:. This code is Copyright by Eric Albert ejalbert cs.

Projects other than BrowserLauncher2 may have also updated the original BrowserLauncher to account for changes in browser and default system security settings since Hope you don't mind but I cobbled together all the helpful stuff, from above, and came up with a complete class ready for testing I recast Brajesh Kumar 's answer above into Clojure as follows:.
