Download pdf file from tomcat folder using JSF

Question

Hi I am trying to implement pdf file download functionality by this way .

/* test.xhtml*/

<p:commandButton   actionListener="#{backingBean.download}" update=":form"/>

/ BackingBean.java /

public Class BackkingBean implements serializable{
@ManagedBean
@ViewScoped

public void download(){
String uri = "http://173.24.57.274:8080/ROOT/html/xml/Test new_02.pdf";
URL url = new URL(uri);
File destination = new File("C:/Documents and Settings/microsoft/My Documents/Downloads/sample.pdf");
FileUtils.copyURLToFile(url, destination);
}

}

But when I am clicking on download button I am getting below error.

Caused by: java.io.IOException: Server returned HTTP response code: 505 for URL: http://173.24.57.274:8080/ROOT/html/xml/Test new_02.pdf

I have gone some stackoverflow posts regarding this error but did'nt find any solution which work for me.

What I am missing? How can overcome from this problem.

Answer 1

You should try and encode the URL value. If I spy correctly, there seems to be a Space value within the name of the PDF file. ie "Test new_02.pdf". Encoding the URL using URLEncoder can eliminate issue with "special characters" within the URL and it is good practice to encode URL in java applications

Take a look at http://docs.oracle.com/javase/6/docs/api/java/net/URLEncoder.html

And read the documentation carefully to figure out how to encode the space character.
