Java Development Tools

Hi,

I have a simple requirement where on click of a link/button in my ADF page I need to display an html page stored in network location (e.g. //<hostname>/folder1/folder2/demofile.htm)

I only have the file path and only a substring of the file name so I have to search for the file in the network directory using that substring. Once i have the file name I use af:goLink to navigate to the network path and display the file in the browser.

Here is the piece of code from Managed bean and the jspx

FindFilebean.java

.

.

            path = "\\\\<hostname>\\folder1\\folder2"

            File f = new File(path);

            File[] filelist = f.listFiles();

            File latestFile;

            for(File file : filelist){

                if(file.toString().contains(fileNameSubstring){

                    if(latestFile==null || (latestFile!=null && latestFile.lastModified() < file.lastModified())){

                        latestFile= file;}

                    }

                }

path = latestFile;

.

.

FindFile.jspx

<af:goLink text="Traveler Print" id="gl1"

                                           destination="#{viewScope.FindFilebean.path}" targetFrame="_blank"/>

                                <af:popup childCreation="deferred" autoCancel="disabled" id="p1"

This works perfectly fine when I run it local integrated server, but i get a null pointer exception on accessing f.listFiles(); when deployed on weblogic managed server.

I have also tried the following:

1. Created a servlet and tried to read the file using Buffered output stream and display in an inlineFrame

2. FiledownloadActionListener to read the file and display/download it

Both these approaches work fine locally but display/download a blank page on the server.

Please suggest what I am missing here and if there is another way to achieve this.

JDev version: 11.1.2.4.0

Weblogic Server version: 10.3.6.0

Thanks in advance.
