Help with J2EE Project Management
Hi,
We are about to begin a large J2EE project and are wondering if anyone could help with the following questions:
1. Given the division of labor on J2EE projects (JSP developers, EJB developers, application deployers, etc...), what are "best practices" for building a team and ensuring that they communicate well after the design phase? How will the left arm know what the right arm is doing?
2. What documentation should be produced during the design phase to give to the developers? Will this allow them to go off and develop independently of each other?
3. Is there a "best practices" document anywhere on J2EE project management?
Thanks in advance!!
Hi,
I feel any project to start with should have a prior planning,that too particularly for Object oriented programming projects,I feel UML is the best tool for entire process.I think rational software has got lot of Project Management Tools(PMT) and products at all stages.Please go through the rational.com site and hope you could find some info.I feel the answer to your second question is partly 'yes' and partly 'no'.The modules that you can split it up which have got some independent attributes,but it should not be too much in your project,then it affects the work matrix/There should be a optimal process to decide and that you can yourself formulate depending on the time frame,either way the last step of build or integration is not flexible enough that you should mind,modular flexibility can be there but the integration stage you are tied with a fixed process.So plan accordingly using a PMT tool for any project that matters and all the best.Bye

HP Application LifeCycle Management - URL for use with another Project Management Tool
I'm trying to find a way to get a ALM Requirement URL that will work with other applications. The URL from the COPY URL option (when right-clicking on the requirement) works for e-mails but I can't seem to get it to work for another project management application (Daptiv). We would like to insert the QC Requirement link to another application where the user can access the requirements directly when clicking on the QC hyperlink.
We have HP Application Lifecycle Management Software Version 11.00 Enterprise Edition.
Any help is greatly appreciated.
Thanks.As Abhishek mentioned we dont need a calc manger or EPMA to migrate classic planning applications. You just need to log into shared services, expand file system and take a file system export, paste the export to the destination environment, now use it as a source and perform an import in the shared services of destination server. It worth having a look at:

Collage Students need help with Java project(Email Server) whats analysis?
Hi im studying in collage at the moment and i have just started learning java this semester, the thing is my teacher just told us to do an project in java , since we just started the course and i dont have any prior knowledge about java i was wondering if some one could help me with the project.
i choose Email Sevice as my project and we have to submit an analysis and design document , but how the hell am i suppose to know what analysis is ? i just know we use ER diagrams & DFD's in the design phase but i dont know what analysis means ?
could some one tell me what analysis on an email service might be? and what analysis on a subject means? is it the codeing involved or some thing coz the teacher told us not to do any codeing yet so im completly stumped,
oh and btw we are a group of 3 students who are asking u the help here coz all of us in our class are stupmed ?IN case any one is interested this is the analysis i wrote
ANALYSIS
Analysis means figuring out what the problem is, maybe what kinds of solutions might be appropriate
1. Introduction:-
The very definition of analysis is an investigation of the component parts of a whole and their relations in making up the whole. The Analysis done here is for an emailing service called Flashmail, the emailing service is used to send out mails to users registered with our service, these users and there log activities will be stored in some where, the most desirable option at this time is a Database, but this can change as the scope of the project changes.
2. Customer Analysis:-
We are targeting only 30 registered users at the moment but this is subject to change as the scale changes of the project .Each user is going to be entitled to 1MB of storage space at this time since we lack the desired infrastructure to maintain anything higher than 1MB but the end vision of the project is to sustain 1000 MB of storage space while maintaining a optimal bandwidth allocation to each user so as to ensure a high speed of activity and enjoyment for the Customer.
The Service will empower the user to be able to send, read, reply, and forward emails to there specified locations. Since we are working on a limited budget we can�t not at this time enable the sending of attachments to emails, but that path is also left open by modularity of java language, so we can add that feature when necessary.
3. Processor Load Analysis:-
The number of messages per unit time processing power will be determined on hand with various algorithms, since it is best not to waste processor power with liberally distributing messages per unit time. Hence the number of messages will vary with in proportion to the number of registered users online at any given time.
4. Database Decision Analysis:-
The High level Requirements of the service will have to be decided upon, the details of which can be done when we are implementing the project itself. An example of high level requirements are database management, we have chosen not to opt for flat files because of a number of reasons, first off a flat files are data files that contain records with no structured relationships additional knowledge is required to interpret these files such as the file format properties. The disadvantages associated with flat files are that they are not fast, they can only be read from top to bottom, and usually they have to be read all the way through. Though there is are advantages of Flat files they are that it takes up less space than a structured file. However, it requires the application to have knowledge of how the data is organized within the file.
Good databases have key advantage over flat files concurrency. When you just read stuff from file it�s easy, but tries to synchronize multiple updates or writes into flat file from scripts that run in different process spaces.
Whereas a flat file is a relatively simple database system in which each database is contained in a single table. In contrast, relational database systems can use multiple tables to store information, and each table can have a different record format.
5. Networking Analysis:-
Virtually every email sent today is sent using two popular protocols known as SMTP (Simple Mail Transfer Protocol) and MIME (Multipurpose Internet Mail Extensions).
1. SMTP (Simple Mail Transfer Protocol)
The SMTP protocol is the standard used by mail servers for sending and receiving email. In order to send email we will first establish a network connection to our SMTP server. Once you have finished sending your email message it is necessary that you disconnect from the SMTP server
2. MIME (Multipurpose Internet Mail Extensions)
The MIME protocol is the standard used when composing email messages. -
Need help with calculator project for an assignment...
Hi all, I please need help with my calculator project that I have to do for an assignment.
Here is the project's specifications that I need to do"
"""Create a console calculator applicaion that:
* Takes one command line argument: your name and surname. When the
program starts, display the date and time with a welcome message for the
user.
* Display all the available options to the user. Your calculator must include
the arithmetic operations as well as at least five scientific operations of the
Math class.
-Your program must also have the ability to round a number and
truncate it.
-When you multiply by 2, you should not use the '*' operator to perform the
operation.
-Your program must also be able to reverse the sign of a number.
* Include sufficient error checking in your program to ensure that the user
only enters valid input. Make use of the String; Character, and other
wrapper classes to help you.
* Your program must be able to do conversions between decimal, octal and
hex numbers.
* Make use of a menu. You should give the user the option to end the
program when entering a certain option.
* When the program exits, display a message for the user, stating the
current time, and calculate and display how long the user used your
program.
* Make use of helper classes where possible.
* Use the SDK to run your program."""
When the program starts, it asks the user for his/her name and surname. I got the program to ask the user again and again for his/her name and surname
when he/she doesn't insert anything or just press 'enter', but if the user enters a number for the name and surname part, the program continues.
Now my question is this: How can I restrict the user to only enter 'letters' (and spaces of course) but allow NO numbers for his/her surname??
Here is the programs code that I've written so far:

What you could do is checking the input string for numbers. If it contains numbers, just reprompt for the Name.
AND you might want to ask yourself why the heck a calculator needs to know the users Name. -
Help with J2EE SDK 1.4 Virtual Servers please!
H!
Are we doomed to have just one virtual server pointing to port 80??
I have a Win2K computer with J2EE App Server 1.4. In this computer I stopped the IIS 5.0 in order to use the HTTP Server included with the product. I also run the DNS on the same machine with 3 domains. All name resolutions for these 3 domains work fine.
Now I want to enter to any of the 3 domains freely and execute JSP apps. But I don't want to enter ports numbers like this:
http://www.mytest.com:8081/hello.jsp
I just want to enter:
http://www.mytest.com/hello.jsp
So I defined a new http-port listener pointing to the 80 port on this server. With no SSL support.
Name: http-port80
IP Address: 0.0.0.0
POrt: : 80
Then I defined a new virtual server using the http-port listener. I set the following fields:
ID: mytest
Hosts: www.mytest.com
HTTP Listener: http-port80 (This is the name of the port listener)
Everything seems to be fine. I can enter http://www.mytest.com and call the hello.jsp it's ok.
But then I create a new virtual server for http://www.mytest2.com exactly as the one for the www.mytest.com, except for the host field: http://www.mytest2.com
Then when I restart the app server I got the message on the log: "Port already in use".
I don't want to enter http://www.mytest2.com:<port> but I've read that you cannot assign the same http-listener to 2 virtual servers, so I created another listener pointing to the same port 80. But I still have the same error.
Any ideas how to handle this?
Am I doing something wrong on the configuration?
Thank you very much!!I can help you out with this, because I just solved this problem using the Apache web server 2.0 with mod_proxy and mod_proxy_http.
this is how the configuration works.
setup sunone creating one virtual host for each http-listener on a different port. and make sure these ports are any port except the 80. -- we will configure apache on this port and then use it as a reverse proxy to get to our hosts.
like this
virtual-listener-1 - port 8081
virtual-listener-2 - port 8082
virtual-listener-3 - port 8083
virtual-host-1: www1.domain.com bind to: virtual-listener-1
virtual-host-2: www2.domain.com bind to: virtual-listener-2
virtual-host-3: www3.domain.com bind to: virtual-listener-3
now download apache with all the modules http://www.apache.org
in your httpd.conf add the following lines of code.
#the code below will tell apache to enable the proxy for your host
<IfModule mod_proxy.c>
# Proxy Server directives. Uncomment the following lines to
# enable the proxy server:
ProxyRequests On
<Proxy *>
Order deny,allow
Deny from all
Allow from www1.domain.com
Allow from www2.domain.com
Allow from www3.domain.com
</Proxy>
# Enable/disable the handling of HTTP/1.1 "Via:" headers.
# ("Full" adds the server version; "Block" removes all outgoing Via: headers)
# Set to one of: Off | On | Full | Block
ProxyVia On
# End of proxy directives.
</IfModule>
NameVirtualHost *:80
<VirtualHost *:80>
ServerName www1.domain.com
<Location />
Order allow,deny
Allow from all
ProxyPass http://sunoneserver:8081/
</Location>
</VirtualHost>
<VirtualHost *:80>
ServerName www2.domain.com
<Location />
Order allow,deny
Allow from all
ProxyPass http://sunoneserver:8082/
</Location>
</VirtualHost>
<VirtualHost *:80>
ServerName www3.domain.com
<Location />
Order allow,deny
Allow from all
ProxyPass http://sunoneserver:8083/
</Location>
</VirtualHost>
note the sunone server indicates the server where you installed sunone-as (J2EE 1.4). this will give you the result you are looking for: all three of these sites will run on port 80 and each of them will respond to a different web application on sunone.
there are naturally limits because when you run out of ports on your application server this won't work any more but then again there are about 60000 of those free and i don't think you will be able to run that many sites on one server anyway.

Hi All,
My PM has asked me to prepare a project plan but I am quite new to MS project (in fact this is the first time I am creating a complete project plan) and any project management software as such.
My requirements is that I have three different entities (A, B, C) responsible for the tasks in the project. I have created separate custom fields for each and entered their name against the tasks. Now, I need to include % of work completed for each of them
separately so that each task can be independently tracked against the entity responsible. Some of them are combined tasks where in A & B are to complete those and some are individual.
For example, Task 1: A - 50%, B - 30%, C - 60%
Task 2: B - 75% etc.
So I added % of Work Completed against each entity (in adjacent columns), but when I update one it gets reflected in the other columns as well.
Is this the right way to do it? Is there any other way to do it? Plz help.
Regards,
AhmedHi Ahmed,
If I understand your question correctly, I think you can use Task Usage view to manage individual/entity % work completed against a particular task.
I have tried to put together an example:
I have assigned the entities (resources) against each task
and then used the Task Usage where I've inserted the %work completed to track entities (resources) against each task
There are also other options/views that can be used, like Resource Usage
Hope this helps

Thanks
SandyR.One way is to
1) pass a reference of the Window object to the USDListener class, and set a local Window variable say call it window, to this reference.
2) Give the Window class a public method that returns a String and allows you to get the text from USDField. Same to allow you to set text on the euroField.
3) Give the Listener class a Converter object. -

Help with printing projects from photoshop elements
I have been trying for a few days now to print a project from my elements 6 program and the colors are way off. I just recently got a new printer, Epson artisan 837. I didn't have this problem with my last printer. The printer prints normal from other programs, and I've tried a ton of different printing settings and I still can't get it. Help please.
In Editor, go to Edit menu>color settings
Check "Always Optimize Colors for Computer Screens".
In the printer settings, check Printer Manages Colors.
The point is that you don't want both PSE and the printer to manage colors. -
Help with creating a management plugin in OEM.
Hi Everyone ,
I was trying to create a management plugin - which would monitor a WLS instance.
So we created a plugin using the emjmxcli tool , and it worked fine.
Background info :
WLS side - managed server running - has 2 channels HTTP/ HTTPS - and 2 virtual hosts created : one for each channel. Applications are deployed into this virtual hosts.
EM side - after creating a target of the particular type (from management plugin) , drilling down into the metrics gives different attributes
eg : "com.bea:Name=Default[http],ServerRuntime=ManagedServer_1,Type=ServerChannelRuntime" ------ where ServerChannelRuntime = mbean i am monitoring.
Among these , there are 2 attributes , one for each Channel which i specified earlier.
Now the issue is - I need to modify the plugin target/collection xmls so to SUM up these 2 attributes (HTTP and HTTPS) , and filter out all other attributes which are shown. It takes up unnecessary space in db as well.
So i tried - adding an <executiondescriptor> -
<ExecutionDescriptor>
<GetTable NAME="Metric" USE_CACHE="TRUE_IF_COLLECT"/>
<GetView NAME="ChannelHTTP" FROM_TABLE="Metric">
<Filter COLUMN_NAME="ObjectName" OPERATOR="EQ">com.bea:Name=Channel_HTTP_1,ServerRuntime=ManagedServer_1,Type=ServerChannelRuntime</Filter>
</GetView>
<GetView NAME="ChannelHTTPS" FROM_TABLE="Metric">
<Filter COLUMN_NAME="ObjectName" OPERATOR="EQ">com.bea:Name=Channel_HTTPS_1,ServerRuntime=ManagedServer_1,Type=ServerChannelRuntime</Filter>
</GetView>
<JoinTables NAME="BothChannels" >
<Table NAME="ChannelHTTP"/>
<Table NAME="ChannelHTTPS"/>
</JoinTables>
<GroupBy NAME="result" FROM_TABLE="BothChannels">
<AggregateColumn NAME="NumberOfReq" COLUMN_NAME = "NumberOfReq" OPERATOR="SUM" />
</GroupBy>
</ExecutionDescriptor>But this didnt help. So if any one could help out with this , it would be great.
I need to -
1. Sum up 2 attributes.
2. Filter out other attributes which appear automatically from the mbean.
ThanksI found a great tutorial here:

Any help with crashing project?
Hello, I am a little new to Premiere pro but I don't feel this is a PEBCAC problem. I have been working for 2 weeks on a project and everything has been fine. I exported my sequence the other day and nothing to report, all good. Today I open the project and as soon as all the media is loaded, everything seems normal. It will sit there for ever idle no problems. As soon as I move the timeline, the program crashes.
I have not changed any media, changed any software, changed any hardware since my last session. I have opened a new project and tried to import the previous project which worked until I moved the timeline.
Seeing as everything was fine last time, I don't see how it could be a corrupt media file? The next step was to try to move the initial files so they won't import and see if the process of elimination might work.
Reading the event log (and I'm just making assumptions as I am not familiar with the information contained) it looks like [perhaps there is something wrong with the render engine? When I scrub the timeline the renderer is faulty and crashed the program?? (Imagerenderer.dll)
I have 18gb of RAM, I7 PC on windows 7 CS5 NVIDIA Quadro FX1700 video card. There doesn't seem to be a logical explainantion seeing as nothing has changed. The error log is below.
Any help would really be appreciated.
Thanks!

Q - since this error indicates images, what kind of images (JPG, PSD, etc) and what pixel dimensions?

Please Please Help with Projectile Project Here are the Codes
I've got three(3) classes a Model, a view, and a controller.
This is a project about projectiles.it is an animation of a cannonball being fired from a cannon and travelling under the effect of gravity.A cannon fired at angle 'a' to the horizontal and with an initial speed 's', will have an initial velocity given by:
vx := s * cos(a);//velocity x equals the speed multiply by the cosine of angle a.
vy := s * sin(a);//velocity y equals the speed multiply by the sine of angle a.
Here are the code.

if the cannon ball land in the bucket it should stop and the animation should indicate a 'hit' in some way. maybe by displaying a message.
if the cannonball hits the outside of the bucket it should bounce off.
Extra Notes.
1) The acceleration due to gravity is 9.8m/s to the (power of (2) eg s2.
2) The distance travelled in time t by a body with initial velocity v under constant acceleration a is:
v * t + a * t.pow(2) div 2;
The velocity at the end of time t will be v + a * t.
Distance is measure in pixels rather than meter so for simplicity we use 1 pixel per meter

Please Help with Physics Project Here are the codings
I've got three(3) classes a Model, a view, and a controller.
This is a project about projectiles.it is an animation of a cannonball being fired from a cannon and travelling under the effect of gravity.A cannon fired at angle 'a' to the horizontal and with an initial speed 's', will have an initial velocity given by:
vx := s * cos(a);//velocity x equals the speed multiply by the cosine of angle a.
vy := s * sin(a);//velocity y equals the speed multiply by the sine of angle a.
Here are the code.

When i pressed the fire button nothings happens. I'm going crazy. Please please help!Hi,
U put something on forum and keeping silence.If it is not necessary dont put in forum.I moved your cannon ball.If u want continous movement I need some more information.

HELP with Lenovo Power Manager
Hi, I recently my new Thinkpad T530 and I accidentally uninstalled Power Manager. I re-installed it. Now when ever I log on It says, "RUNDLL: There was a problem starting C:/Program.
