- maven and ear packaging
okay, i just needed to place some files in the ear file.

If so, look for the header ‘X-Forwarded-For‘ of your request object. (request.getHeader(”X-Forwarded-For”)).

I got this line in the JMP user guide. By the way, JMP stands for Java Memory Profiler.
Oh yeah, we’re now looking for possible memory leaks.
I also found out that JMP can be installed in Gutsy Gibbon using apt-get.
After installing, I tried running […]
- Java to DWR - decrease the file size of your javascript
It was until yesterday i realized I was doing something wrong with regards to JAVA-DWR interfacing as pointed out by Cata.
Backgrounder: in dwr.xml we define the classes(services) we use, which generates javasript which we will call facades and these can be imported in our javascript files.
My practice: In my js file, i simply import those […]
