If you want to retain the file permissions of a file that you copy with ant you must use the <exec> command instead of? <copy>.
So, instead of:
<copy file=”${source.file}” tofile=”${dest.path}/${dest.file}” overwrite=”true”/>
Use:
<exec executable=”cp”>
? <arg value=”-pf”/>
? <arg value=”${source.file}”/>
? <arg value=”${dest.path}/${dest.file}”/>
</exec>→ Continue reading “Preserving File Permissions When Copying Files with Ant”
I am writing an application that copies files from a Samba share using the JCIFC Java CIFS Client Library (which, btw, is a very helpful, widely used, and well developed project).
As usual I am under the gun to get something up and running so I do not have the luxury to explore all of the details as much as I would like. My application gets a directory listing of a Samba share and then spawns a new thread for → Continue reading “java.lang.OutOfMemoryError: unable to create new native thread Exception When Using SmbFileInputStream”
Often times I will be building a Java program that will either be run from a command-line or as a system service. In most cases, during development, I’ll be running it directly from the command-line and will want to kill it by pressing control c on the keyboard.
When I do that I want to make sure that my program cleanly exits, closing any open files, socket connections, database connects, or what have you.
To do so, you must invoke → Continue reading “Adding a ShutdownHook to a Java Program to Enable Clean Exit on CTRL-C”

Once I am finished I will go back and re-write it to follow more of a how-to/guide type format. In the meantime, it might seem a bit disjointed.

The ability to generate HTML or .JSP fragments that you can include on multiple pages of your site enables you to re-use code and increase maintainability.
However, if you need to include functions (or methods) and fields (or variables) in one fragment that is included on a page and then utilize them in another fragment included in the same page Eclipse will give you compile errors because it concludes that your references are out of scope.
The solution is quite → Continue reading “Compiling .jsp Fragments in Eclipse”
