I am currently developing a java application that interfaces a computer
to an external device that uses an RS232 port.  I have an RS232/USB
addapter and the application has been able to successfully interface
the computer to the external device using the javax.com.properties

Our JSP-based app gets distributed to end users, who get to edit and
customize the pages. At the moment, we make them put Java code directly
in the page to get info out of our app. This is clearly not suitable for
non-Java developers.

I need to extract some data from a web page that I'm parsing, using
regular expressions to find matches I'm interested in.  In particular,
I'm trying to extract the text from between <A> and </A>.  The <A> does
have several attributes which I don't care about.  The reg. exp. I'm

I'm trying to build a small screen scraper to extract info from a
certain website, entering a search into a search engine & then parsing
the results.  I saved a few test pages on my computer to use, which
work fine -- everything I'm trying to extract is found & parsed

it seems that there is a bug in java Reflection class [
java.lang.reflect ] that will allow an illegall access permission to
private fields and methods.
for example take a look at the code below :

My backup program is intended to work on both Apple OS X and Windows.
It happily reads and writes files on both systems, except when writing
to the CD drive on the Windows system.  When I use getCanonicalPath,
the message from IOException is:

I have a signed applet that appears on every page.  I need to save and

be the way, but it seems you can only store Strings.  Any other ideas
anyone?

Hello Dears,
i have developed a web application in which i am exporting my reports
to pdf. its a time consuming process. I want to have a progress bar
that will keep me inform about current progress.

I need to use classes that require conflicting classpaths, and I have

classes it uses are resolved from their classpath, and then

I have an rpc/encoded webservice to work with. I modified the
wsdl to add a schema in the wsdl:types section so that I can use
wsdl2java to generate java objects. The particular implementation is
Axis''s version.

I am new to Java, I want to access a C++ Class containing function with
variable # arguments (vm_args). Could any one suggest me a solution.
Thanks in advance

I have a lot of forms on a page and each form with a action button that
will send the information to the servlets. And after I click the action
button, I can only get those information within the form. Is there
anyway I can get parameters outside that form at the same time?

Is there a popular idiom for a switch statement that takes a string? I
want to emulate something roughly like:
switch (myString) {

Obviously the canonical use of semaphores is to ration access to a
finite number of resources, say hard disks or memory buffers.  It has
occurred to me that a semaphore could, in theory, also be used to
ration permission to send messages in a TCP-like protocol, where
