Starting Tomcat using jsvc and jpda

This is mostly just a message for anyone else looking for an answer to how to start Tomcat as a daemon with webapp remote debugging enabled.
There is a real lack of information on how jsvc works when starting Tomcat under *nix. I'm using Solaris 10, but this should be very similar on most Linux systems.
There is a simple shell script called tomcat in /etc/init.d that starts the cat as a daemon. The change needed to use remote debugging from Eclipse is to enable jpda. This is done by setting the CATALINA_OPTS to include the jpda settings.
Here's the modified line in the script:
CATALINA_OPTS="-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8000" If it worked you will see a line like "Listening for transport dt_socket at address: 8000" in your catalina.out. And now Eclipse can do remote debugging on port 8000.
If you use the catalina.sh script to start the cat all you need is
./catalina.sh jpda startsince it defaults to these settings, that's where I found them.
And of course there are dukes for suggestions.

You can look at this URL
http://www.java-tips.org/content/view/119/40/
Response Code 404 is recieved when the path of servlet is not correct.
Servlet classes needs to be placed in right directroy under tomcat server.
URL typed in browser for accessing web applciation should be correct.
Below URL explains the Runtime.exec method

Unable to start Tomcat using runtime class in windows 98

hi,
I am using a runtime class which calls a batch file, that calls statup.bat for starting tomcat.
This works perfectly in windows NT,2k. But on win 98, the tomcat window opens and closes within no sometime.
In my class i call the first batch file starter.bat using
Runtime.getRuntime().exec("%COMSPEC% /c start e:/starter.bat");
(I tried with command.com also...)
Starter.bat has the line
call E:\jakarta-tomcat4.1\bin\startup.bat.
Is there anyother way to start the tomcat process and keep it running on windows 98. Anyone with anyclues pls help.
Thanks in advance.

This is the Runtime class i am using... Sometimes tomcat gets closed and sometimes just hangs... (putting it in for better understanding..)
public class Starter {
     public static void main(String[] args) {
          String com = "%COMSPEC% /c start
C:\\PACS\\SFAApp\\tomcat\\startup.bat";
               try     {
                    Runtime rt = Runtime.getRuntime();
                    Process pr = rt.exec (com);//Starting tomcat
                    try
                         pr.waitFor();
                    catch (Exception e)
                         e.printStackTrace();
               catch (IOException ie) {
                    System.out.println("IOException caught" + ie);
                    ie.printStackTrace();

Thanks in advance.

did you edit the catalina.bat file in Tomcat?
It requires that you do so...I don't think by default it will have your JDK that resides on your machine.
I've edited various versions of Tomcat and the catalina.bat, server.xml and web.xml files before, and usually I've just about always had to add a line (SET JAVA_HOME) and then the variable %JAVA_HOME% will read it.

Cannot make .war file using tomcat with eclipse and ant

i have made all necesary configuration for deploying application using eclipse and ant for the tomcat server.
when i start the server by clicking the tomcat icon on eclipse toolbar, the message is prompted that "missing application web.xml and using defaults". i have placed the web.xml file in the web/WEB-INF directory of the source project directory.
also when i use ant by right-clicking on the build.xml file and choose Run as ant.. the process creates a desired .war file in webapps folder of the tomcat server but that war file does not works.
where is the error i cannot figure out.
am attaching the code of build.xml for reference.

So is context.xml actually overwriting the settings found in server.xml?I think so. The way I understand it is the the context.xml file saves you from having to edit server.xml. It is preferred for each web app to do its own config, rather than lumping them all together in server.xml.
And what would be the best way to create the war file? IAt its heart, a WAR is just a zip file with its contents laid out in according to the specification of a web application directory structure.
So the simplest way to make a war file is to zip up your directory structure with a tool like winzip, and rename it to be myApp.war.
Regarding ant, I would recommend you take a look through [url http://jakarta.apache.org/tomcat/tomcat-4.1-doc/appdev/index.html
]this tutorial. It explains the basics of website layout, configuration and deployment.
On [url http://jakarta.apache.org/tomcat/tomcat-4.1-doc/appdev/source.html] this page in particular, it includes a link to a basic ant file that you can use as a starting point.

Is it a USB hard drive? USB hard drives have the problem of not giving full speed if they are hooked up on the same bus as keyboards and mice. Double check your profiler to make sure that is not a problem. If it is Firewire, make sure there aren't other firewire devices in use at the same time. I recommend not only keeping a Time Machine backup, but also a clone, and if you do use Time Machine, to make sure the Time Machine drive or partition is at least twice the size of the original drive.

I have just started to use Muse for our design agency and learning how to build ourselves a new site, I have managed to create a basic lightbox which contains sliding images, what I need to do now is have a pop up window which goes into detail about the projects, what I would like is a piece of text or icon that when you roll over it and then click a separate window pops up with additional information in, once finished reading the info you can then click to close the box, any advice on how to do this?

The best way to do what you're asking is with the Composition widget. Start with the Tooltip preset, which, by default shows the info on rollover. You can change the option to show on click, which is what you're after. You can also add the close button or have the info disappear on rollout.

The only option I'm being given is to create an lCloud account.
Any guidance? Thanks.

The last thing you want is a second iCloud account. Try logging out and back in in System Preferences. If that doesn't work, I'd get AppleCare on the line.

I have an MacBook Pro 10.6, using disk utility I tried to verify my disk, but it came up with the message, please use your start up disk, I tried this, starting the computer up and pressing C, but it ejected the disk, the same thing happened while I running the computer. Is the hard drive damaged as laptop doesn't seem to recognize the start up disk ? If so, I presume I will have to put in a new one.
There haven't been any problems with the computer, apart from a sticky curser,I have run a permissions programme from disk utility, there were a lot of different ones, but it seem to be able to fix them.
Any comments or ideas ?
Thank you in anticipation.

First backup your users files off the machine to a external storage drive (not TimeMachine!)
Most commonly used backup methods
Next to startup from the disk, have it inserted, hold c or option/alt (wired or built in keyboard) and then boot the computer and or select the disk when it appears and click the arrow.
Disk Utility is under the Utilities menu on the second screen.
Step by Step to fix your Mac
If you used the wrong 10.6 disk, it will spit it out or have issues, use the one that came with that machine or if it's defective, call Apple for a new one.

When I use my IPhone 4S to view the Shaw Go Movie Central App when I am at home I only use WiFi which is automatic, I start watching a show and sometimes I will get a message like "you can not use your cellular for video playback" or something close to that. Then I received an email from Telus saying I had used my 3G instead of Wi-Fi using 75% of my data. How can this happen when I'm on Wi-Fi at home? If it switched to 3G for some reason I should have been disconnected and not just transferred to 3G network using up my data. What is the fix for this??

It doesn't have to be that complicated, Verizon iPhones come unlocked, just tell VZ you're going on Holiday/Traveling and suspend the service, no need to pay for service if you're not going to be using it. Pick up local SIM cards in the countries of your choosing, pop them in, re-activate iMessage and you're set!
I recommend getting a SIM card from the Three network in England, they have great EU roaming rates and free like-home roaming in Italy.
Set your phone's region to match the country you're in, it'll save from some headaches when calling local/international numbers.
To answer your questions,
1. If you choose not to have a local SIM card, it is good to keep your phone in Airplane mode to save battery.
2. Make sure the two iPhones have different names to reduce sync/restore issues.
3. If husband has an iPhone also, you can chat with iMessage/Facetime, just give him heads up about the new number you'll have. Otherwise, use Whatsapp if he's got an Android. You can activate Whatsapp with your American number or the international number if you choose to get a SIM in Europe.
Also, Get the MagicJack app and/or Google Hangouts, both of those apps provide you with free calling to the USA and Canada using any internet connection. Google Voice is another good way to SMS across the seas.
Let me know if you need any more tips for iPhoning across the pond.

It's a tray loading drive, there should be a little hole next to it, just large enough for a paper clip. Stick the end of the paper clip in it and the tray should open.

Bought a Mac Mini. at 18 day's old it started to lock up and not function. Took it in and they wiped and reinstalled it. Well at 24 day's old it's been sitting in the box not being used. First and last Mac for me. But can I get something for the junk?

I have pulled it out of the box and put 2 Mac approved mem sticks in it to boost it to 8 Gigs mem and it still locks up and freazes.. So many people told me Mac was the way to go... 1500 dollers could have bought me a great pc laptop. Now I have a wirless mouse keyboard and a mac mini (aka Brick) that allowed me to donate money to a cause that is helping buildings and companies out side of the US. While I have junk.. It's still under warranty and I reinstalled the os after the new mem sticks. Again.. locks up and does nothing. What can I do with this? Toss it in the trash? Any info on what I might do with it.. Please help!

It would be most helpful if you updated your system information:
Please reconcile the following
at 18 day's old it started to lock up and not function. Took it in and they wiped and reinstalled it. Well at 24 day's old it's been sitting in the box not being used.
... I reinstalled the os after the new mem sticks.
If your Mini is anything less than six months old it would be running Lion, not 10.6.1, nor would it have been necessary to "reinstall the OS". Any help that anyone can provide is predicated on your system configuration so it's important.
If you are running Lion then boot your Mini while holding the D key. This will load Apple Hardware Test which will enable you to test your memory. "Mac approved" memory is sort of vague, and even memory that is allegedly designed to meet your Mini's specification may fail. There few reputable memory vendors.
"Apple installed" memory is more meaningful, and indicates Apple has tested it and guarantees its function. Otherwise all bets are off with a claim of "Mac approved". You will have to verify that yourself with Apple Hardware Test.
If your Mini was running, or ever ran OS 10.6.1 for that matter, it is close to three years old.
You must clear up these uncertainties before anyone can help.
