Tomcat Startup problems using eclipse
Hello together!
I want to create a JSP page in eclipse.
I use eclipse-wtp-1.0 and tomcat 5.5.12.
I have set the JAVA_HOME, TOMCAT_HOME and CATALINA HOME.
I included this 2 directories in eclipse.
But now I get the following error:
23.02.2006 08:37:31 org.apache.catalina.startup.Catalina load
WARNUNG: Can't load server.xml
23.02.2006 08:37:31 org.apache.catalina.startup.Catalina load

Could anybody pls help me.
Thanks a lot.
The first posting was refering to a java project.
Now I tried to make a dynamic web project.
There i have the mistake:
First a pop up appears and says: Could not fid the main class. Programm will exit.
and then:
java.lang.NoClassDefFoundError: org/apache/catalina/startup/Bootstrap
Exception in thread "main"
Does anybody know how I create a project (JSP/JSF), so that I can start the page with for example tomcat.
If one of you has a toturial where there are exactly the versions written, as I did everything refering to an toturial.
Pls give advice, how to get it started.
Thanks in advance.

Hi,
I am trying to use Eclipse but I encountered some problems. I drag and drop an application of mine, into a Java project in Eclipse, I try to run and I get :
Usage: javaw [-options] class [args...]
(to execute a class)
or javaw [-options] -jar jarfile [args...]
(to execute a jar file)
where options include:
-client to select the "client" VM
-server to select the "server" VM
-hotspot is a synonym for the "client" VM [deprecated]
.Whats that about?I think it would be better to build a new project in Eclipse with the same name as your old project, and with the same java class names as your old project (with no content) in a similiar package structure (this is especially easy if the project is small). Then copy/paste the contents of the java classes into the ones in Eclipse. Then add the jar files to the lib folder that are missing (then add them to the project via the menu buy right clicking on the project icon, going to properties, etc).
Drag/dropping a project into eclipse will probably not configure the missing jar files, etc that Eclpise needs. Note if your project is a tomcat project, then in eclpise, create a tomcat project and configure its settings such as where the tomcat server is located and what version of java jdk your using for the project.
However, if you have an already existing Eclipse project you only need to 'import' the project via the Eclpise menu. -
Jdk 1.5.0_04 and Eclipse with SuSE Linux - startup problems with Eclipse
Hi,
I have SuSE Linux 9.3 and just downloaded Jdk 1.5.0_04 and Eclipse IDE 3.1 for Linux.
I have sucessfully installed Java in the following directory under Linux:
'/usr/java/jdk1.5.0_04'
And I also have downloaded Eclipse IDE 3.1 for Linux. I have unzipped it into the following directory:
'/home/juergenkemeter/bin/eclipse/eclipse
I have chosen the upper Java JRE in the Eclipse preferences.
Now to my problem:
Sometimes it happens that when I startup Eclipse or try to runa java program, Eclipse is shut down with a) no comment at all, or b) with an error message "JVM terminated. Exit code = 1 (...)". I can send the picture of the whole screenshot of the error message if it helps.
Now I think that this is due to wrong installation paths of the Jdk and Eclipse?! Perhaps there are some conflicts regarding user rights (admin and the normal user 'juergenkemeter'.
If anyone has suggestions, that would be helpful. Its nasty when Eclipse shuts down while programming...
cheers,
J�rgenI only used the getSystemResource because it is slightly more convenient. The
getResource version requires a "/" in front of the filename, as in:
java.net.URL imageURL = getClass().getResource("/" + imageName);
System.out.println("Loading icon: " + imageName);
for (int i = 0; i < 32000; i++)
System.out.println(i);
icon = new ImageIcon(imageURL);
Unfortunately, this still deadlocks after a few thousand hits.
Of course, I don't need thousands of icons in my application, but the real-world issue is that the program locks up every few times it is started, which is a real drag for the customers!
I suppose the InputStream way would work, though it is not very elegant compared to loading the resource in the usual manner. I'll try it if there are no other suggestions.
Thanks,

Hi all!!
I'm using a BOE XI 3.1 SP2 with Apache Tomcat Was, in a Windows 2003 VMware image...
I'm having problems starting tomcat.... It's really slow... and I don't know what to do.
I've tried to modify the tomcat configuration, adding more maximum memmory pool... and I have the same problem
any idea???
thanks to all!!I typically set my tomcat memory in the tomcat configuration/java options tab to 384 min/max
I do this because my BM's are set to only run on 768 memory. Also I turn off any unused services in the CMC and make sure they do not start by default (pm services, voyager etc). By default tomcat tries to grab up to 1 gig memory and if your VM doesn't have that available you will see slowness. Also to note tomcat 5.5 in general is much slower than the old 5.0 version that was in XIR2.

Hello Friends,
I am trying to start up Tomcat server, but keep getting error that TOMCAT_HOME is not set. I am using Windows 98. I tried to set the Tomcat_home using
SET TOMCAT_HOME = C:\Tomcat in autoexec.bat
but it gives error - out of enviromental space
How can I set this env. variable? or increase env. space on win98?
Thank you.Hi,
Thanks for your reply.
Buy I still get the following error:
startup.bat -->
Out of enviroment space
Out of enviroment space
Unable to determine value of TOMCAT_HOME
In my autoexec.bat I have created teh following variables:

SET TOMCAT_HOME = "D:\Programs\jakarta-tomcat-3.2.2"
SET JAVA_HOME = "D:\work\Java\jdk1.3.1"

Using Eclipse instead of XCode/Visual C++ ?
Hello everybody,
I am pretty sure this question has already been asked, but I can't get any answer.
Why does Adobe recommend (and distribute samples) based on XCode and Visual C++? Why is there no documentation/projects based on Eclipse ? I can't see any problems using Eclipse, excepted Xcode/Visual C++ based sample projects and docs.
I have been working for monthes on Eclipse and I can only see advantages using it :
Cross-platform : no need to have Windows and OSX projects.
More functionalities : What about functionality such as call hierarchy, classes navigator, automatic suggestions... ?
Better integration : CPPUnit, Maven... What a wonderful world out of reach !
Has anyone among you ever tried to use Eclipse for InDesign plugin development ? What were the problems ? Why Adobe does not event mention the possibility to develop with Eclipse ? Is it really difficult to migrate to Eclipse projects ?
I'd like to read your feedbacks
Thanks in advance.
RegardsHello,
Yes, you can use still use the plugin.
Refer "http://www.oracle.com/technology/products/enterprise-pack-for-eclipse/index.html".

Kindly let me know in as much detail as possible as to what could have gone wrong.
Help would be greatly appreciated.

Problems with Eclipse-Plugin when using JPA in JavaFX
Hi all,
I am trying to develop a small JavaFX application with JPA using Eclipse and the FX-Plugin.
Since I cannot use Annotations in FX code I created Java entity classes that are shadowed by the corresponding FX entities. To associate the Java and FX entites with each other I added a new member to the FX entity of the type of the Java entity. Suprisingly I now get errors that the FX entity cannot resolve the javax.perisistence classes. Those classes are imported in the Java entites without any errors. All entities are in the same package, so I really suspect it's the plugin's fault.
Has anyone experience with this problem?
Thanks,
ChrisThere's something wrong with your code. You need to analyse it.

i can compile into jar successfully but the jar file wouldn't respond.first , it says unable to access jar file .
upon deeper inspection i found that background processes is created behind thus the jar file been activated but the UI doesnt show up? any more idea of where my codes gone wrong? which seems perfect for me
anyway thanks but i still .. it says unable to access jar file -
MSI eclipse plus startup problem
Hi,
I have the MSI eclipse plus motherboard, but I have a strange startup problem.
Sometimes my computer fails to start up. When I try again sometimes it works fine. (without changing any hardware or software configuration)
The Eclipse plus has a small D-led2 panel that shows information about the startup phases.
When my startup fails, the panel mentions: CPU init. And the error Code is FF (this means: power on and first initialize CPU)
(This is the phase just before DDR init).
So the startup fails in a very early stage of the startup process, (before I can access my bios)
When the start up fails, I have to disconnect the power cable, reconnect and try to start again. This is a very uncomfortable situation.
I have the latest BIOS version 21/04/2009 V1.0
I tried the fail-save default options in the bios.
My processor is i7 940
RAM: OCZ DDR3 . 6 pieces of 2GB. 1600Mhz (3 dual channel kits)
Power supply: Corsair 1000Watt
I hope somebody can help me.
Thanks in advancePlease note that the memory controller was moved into the CPU with the i7 - it is no longer part of motherboard chipset (MCH). You're not the first and probably won't be the last to buy the wrong type of DDR3 memory for your i7 rig. People, before you buy; check if the memory you are handing money over for is actually suitable for your CPU. Simple really as they will state they are i7 compatible. The i7 has a recommended maximum voltage of 1.65V for the integrated memory controller, 1.9V is probably a dangerous voltage to set it to (if the BIOS even allows it). To quote the OCZ FAQ:
Quote
The memory supply voltage also powers the receivers and senders on the memory controller with a voltage plane known as VDDQ. Because the Corei7 is manufactured on a 45 nm node, the logic is sensitive to overvoltage and Intel defines the upper safe limit for the Core i7 as 1.65V.
So to answer your question:
Quote
I still have one question: What do I risk with my DDR3 memory that is standard at 1.9V
More than likely, the integrity of the i7 940 itself. You have to ask yourself, "What's cheaper to replace... the RAM or the CPU?" The answer should be simple enough to work out for the average user.
I'd be taking the RAM back if at all possible and exchange/upgrade it for an i7 compatible kit (which will be three/six stick tri-channel, not two/four sticks dual-channel) designed to operate within the 1.5V~1.65V recommended voltage range. The OCZ equivalent (comparing what you currently have) to what you want would be this range. -
I'm trying to establish connection with the database from JSP.When I'm running it's giving the following error
"oracle.jdbc.driver.Oracle.Driver class not found"
I'm using Tomcat 4.1 and database is Oracle 8i.I've already set the classpath."C:\oracle\ora92\jdbc\lib"(Oracle is intalled in C drive).
Kindly help me resolve this issue.
Bye.Tomcat does not use the system classpath.
As far as Tomcat is concerned the classpath for a web app is
1 - web-inf/classes
2 - jar files in web-inf/lib
3 - jar files in [TOMCAT]/shared/lib
4 - jar files in [TOMCAT]/common/lib
If you are going to be using Tomcat's connection pooling, you need the JDBC driver jar file in [TOMCAT]/common/lib
I would recommend you put the file ojdbc14.jar (or equivalent) in the [TOMCAT]/common/lib directory
Restart tomcat, and try again.
Cheers,
evnafets

Quality headphones or earbuds for iPod (obviously :-)
I know there are other topics about this, but I prefer to post a separate one as my question is a little more specific than just "please just recommend me new headphones". So, I'd like to get new earbuds/headphones for my iPod. I've been recommended
