    <p>I build java web Application.</p> <p>I wrote 1 function in my class with 2 argument.If you pass directory path(where <code>.txt</code> files are saved) and filetype as a arguments to that function.It returns all the filenames,which files have with specified file extension.</p> <pre><code> public List&lt;File&gt; ListOfFileNames(String directoryPath,String fileType) { //Creating Object for File class File fileObject=new File(directoryPath); //Fetching all the FileNames under given Path File[] listOfFiles=fileObject.listFiles(); //Creating another Array for saving fileNames, which are satisfying as far our requirements List&lt;File&gt; fileNames = new ArrayList&lt;File&gt;(); for (int fileIndex = 0; fileIndex &lt; listOfFiles.length; fileIndex++) { if (listOfFiles[fileIndex].isFile()) { //True condition,Array Index value is File if (listOfFiles[fileIndex].getName().endsWith(fileType)) { //System.out.println(listOfFiles[fileIndex].getName()); fileNames .add(listOfFiles[fileIndex]); } } } return fileNames; } </code></pre> <p>I tested this function in the following 2 ways.</p> <p>Case 1:</p> <p>I created folder name as <code>InputFiles</code> on my desktop and placed <code>.txt</code> files under <code>InputFiles</code> folder.</p> <p>I pass <code>directoryPath</code> and <code>.txt</code> as a arguments to my function in the following way.It's working fine.</p> <pre><code> classNameObject.Integration("C:/Documents and Settings/mahesh/Desktop/InputFiles",".txt"); </code></pre> <p>Case 2:</p> <p>Now I placed my <code>InputFiles</code> folder under <code>src</code> folder and pass <code>directoryPath</code> as a argument in the following way.it's not working.</p> <pre><code> classNameObject.Integration("/InputFiles",".txt"); </code></pre> <p>Why I am trying case 2,If I want to work on same Application in another system,everytime I don't need to change <code>directorypath</code>.</p> <p>At deployment time also <code>case 2</code> is very useful because,we don't know where will we deploy Application.so I tried <code>case 2</code> it's not working.</p> <p>It's working,when I mention absolute path.If I mention realPath it's not working.</p> <p>How can I fix this.</p> <p>can you explain clearly.</p> <p>I hope, you understand why I am trying case 2.</p> <p>Thanks.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
