    <p>Like the tile said, my Java application doesn't work as it works fine while developing on Eclipse.</p> <p>I finished to build and test my application on Eclipse. It works fine as I expected. I needed to deploy it as a runnable jar so that my client can't use it on their system. I made it a runnable jar through exporting it on Eclipse. When I run the runnable jar, the application starts to work fine for a while and stops on file reading. I haven't had any problem with it on the same code on Eclipse.</p> <p>The source snippet that seems not to work is the following.</p> <pre><code> sfis = new SmbFileInputStream(sFile); in = new BufferedInputStream(sfis); byte buf[] = new byte[(int)sFile.length()]; int pos = 0; int size = 10; int temp; while((size=in.read(buf, pos, size)) &gt; 0){ pos += size; temp = buf.length - pos; if(temp &lt; 10){ size = temp; } } </code></pre> <p>On Eclipse it doesn't cause any problem. It perfectly reads data from SMB connection and finishes its job. But from the jar application, it seems to stop reading from inputstream inside while loop at some point. This is a very strange case that I have never experienced before. And I can't find any solution for this.</p> <p>Is this because of my code or the jar file that might be wrongly made by Eclipse?</p> <p>---------- additional info -------------------</p> <p>With a big help from Edmondo1984, I find out where the jar program stops. When it goes to inputstream from SmbFile, a new thread jcifs.util.transport.Transport is created and the thread is simply blocked and the application creates another jcifs.util.transport.Transport, and so on. After creating 8 or 9 jcifs.util.transport.Transport thread, it is being stuck and doing nothing.</p> <p>The same code, the same jcifs library. But works differently between running on Eclipse and on local machine as a runnable jar. I have no idea why this is happening. </p>

    1. COEclipse might be failing to put the right jars in your "packaged jar" , but this normally results in Classloading errors. Are you testing on the same file?

    2. COYou have to give yourself some visible indicator on what is going on. Ie in a try catch output some kind of meaning ful message on what has happened. An error message above would be useful to debug what is going on.

    3. CO@Edmondo1984 Like you said, if Eclipse failed to add some libraries needed for the application, it won't start. But it starts run. Oh yeah I am testing the same file.

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.
