I have a complex problem that is seeking the community for assisting.

I have a java implementation of a code which has multiple inputs and multiple outputs. In a straightforward case, there can be a java method to take in the exact multiple inputs and churn out the multiple outputs. In some complex scenarios, some of the outputs can be inputs and vice versa.

How can I write a generic simulator to take into account the exact input variables during runtime and churn out the required outputs?

Not sure if anyone can understand what I have said. Thanks.

I have a lot of gif/bmp pictures that are generated in realtime. Is there a way to display them in realtime like a video?

Hi all,

I have many binary files which represent the individual frames for video. When I load the files into a byte[], how is it possible to display it on the screen as though it's like a video playback? In addition, I would want to click on the frame and get back the x & y location. Is it possible to do it? Thank you.

I need to implement something like a running order list to store and retrieve unique Strings, e.g.

1, Orange
2, Apple
3, Pear
4, Durian

If I want to know the index for Pear, it should return me a 3. Subsequently, if I delete Apple, it should return a 2 and 3 when I search for Pear and Durian respectively. Any idea how I can implement a extremely fast algo to get back the indexes as I have millions for records? Thanks!

I have some code which I run as a Java Application. Performance was great. However, when I ported this code to run as a plugin in Eclipse, it was about 5 times slower. This is also consistently slow with codes running in an application server. Is it because of running codes using classloaders? How to I achieve the same level of performance as a Java Application?

My application code has a lot of loops and accesses native com objects.

Hi,

Yes, the package includes some underlying native libraries. It does this using JIntegra. I'm new to these graphics drawing stuff. Is the drawing done soley by Java? Why is it that it uses GDI+ calls instead of using my graphics card? Thanks.

Hi all,

I have a third party software (anyone familiar with ArcGIS Engine for Java?) that plots stuff on my awt frame. The problem is that some of the animation is excruciating slow. It seems to draw using some GDI+ apis which is hogging my cpu cycles instead of my graphics card. Is there anyone who knows how to improve GDI+ performance for my application? Thanks.

Hi all,

I'm sure everyone has tried Google Map before. Has anyone seen a compass navigation panel like that in google map implemented in java before? Thanks.

Hi all,

I want to connect to a NTLM authenticated website via a proxy server. The proxy server is just a passthrough. How can it be done? I have searched the httpclient classes from jarkarta but somehow it does not work in my case. Can anyone help? Thanks.

Hi Ken,

Yes, I wanted a semi transparent frame over a opaque frame. Has anyone done it before? Thank you.

I have some classes that rely on many third party JAR files. The problem is that upon startup, the loading is quite slow. My initial assessment of the slowness is due to the large third party JAR files (approx 50MB) which need to be read and extracted before running. Is there any utility out there to reduce the size of the third party JAR file to the classes I reference in my program? Thank you.

how do we ensure that the JVM can distribute threads across multiprocessors? I have a heavily threaded application too but it seems that it is not using the other processor too.

Can I have a transparent frame in a JFrame/Frame and where I can control the transparency level?

I am using java jvm in winxp on a dual cpu machine. With a single jvm process in the OS, I find that my multithreaded computational program only consumes 50% of the cpu load. How is it possible that the jvm can utilise all the cpu power of my dual cpu machine?
