Where should JavaBeans be placed when using Tomcat?
I want to use a javaBean from inside a JSP, but it seems like Tomcat can't find the bean (...can't find the class).
Is there a particular catalogue where the bean-classes should be placed?
My test-JSP looks like this:
<html>
<head>
<title>Untitled</title>
</head>
<body>
<jsp: useBean id="enBean" class = "ASimpleBean"/>
</body>
</html>
Your problem most probably is that your class isn't a member of a package. A recent change to the way java/tomcat works is that classes in the default package (ie no package) aren't visible any more.
Put your class in a package(eg SimplePackage), so your className would become simplePackage.ASimpleBean
The class files should be placed under your web-inf/classes directory on your web application.
Hope this helps,

<!-- Defines a cluster for this node,
By defining this element, means that every manager will be changed.
So when running a cluster, only make sure that you have webapps in there
that need to be clustered and remove the other ones.
A cluster has the following parameters:
className = the fully qualified name of the cluster class
name = a descriptive name for your cluster, can be anything
debug = the debug level, higher means more output
mcastAddr = the multicast address, has to be the same for all the nodes
mcastPort = the multicast port, has to be the same for all the nodes
mcastBindAddr = bind the multicast socket to a specific address
mcastTTL = the multicast TTL if you want to limit your broadcast
mcastSoTimeout = the multicast readtimeout
mcastFrequency = the number of milliseconds in between sending a "I'm alive" heartbeat
mcastDropTime = the number a milliseconds before a node is considered "dead" if no heartbeat is received
tcpThreadCount = the number of threads to handle incoming replication requests, optimal would be the same amount of threads as nodes
tcpListenAddress = the listen address (bind address) for TCP cluster request on this host,
in case of multiple ethernet cards.
auto means that address becomes
InetAddress.getLocalHost().getHostAddress()
tcpListenPort = the tcp listen port
tcpSelectorTimeout = the timeout (ms) for the Selector.select() method in case the OS
has a wakup bug in java.nio. Set to 0 for no timeout
printToScreen = true means that managers will also print to std.out
expireSessionsOnShutdown = true means that
useDirtyFlag = true means that we only replicate a session after setAttribute,removeAttribute has been called.
false means to replicate the session after each request.
false means that replication would work for the following piece of code:
<%
HashMap map = (HashMap)session.getAttribute("map");
map.put("key","value");
%>
replicationMode = can be either 'pooled', 'synchronous' or 'asynchronous'.
* Pooled means that the replication happens using several sockets in a synchronous way. Ie, the data gets replicated, then the request return. This is the same as the 'synchronous' setting except it uses a pool of sockets, hence it is multithreaded. This is the fastest and safest configuration. To use this, also increase the nr of tcp threads that you have dealing with replication.
* Synchronous means that the thread that executes the request, is also the
thread the replicates the data to the other nodes, and will not return until all
nodes have received the information.
* Asynchronous means that there is a specific 'sender' thread for each cluster node,
so the request thread will queue the replication request into a "smart" queue,
and then return to the client.
The "smart" queue is a queue where when a session is added to the queue, and the same session
already exists in the queue from a previous request, that session will be replaced
in the queue instead of replicating two requests. This almost never happens, unless there is a
large network delay.
-->
<!--
When configuring for clustering, you also add in a valve to catch all the requests
coming in, at the end of the request, the session may or may not be replicated.
A session is replicated if and only if all the conditions are met:
1. useDirtyFlag is true or setAttribute or removeAttribute has been called AND
2. a session exists (has been created)
3. the request is not trapped by the "filter" attribute
The filter attribute is to filter out requests that could not modify the session,
hence we don't replicate the session after the end of this request.
The filter is negative, ie, anything you put in the filter, you mean to filter out,
ie, no replication will be done on requests that match one of the filters.
The filter attribute is delimited by ;, so you can't escape out ; even if you wanted to.
filter=".*\.gif;.*\.js;" means that we will not replicate the session after requests with the URI
ending with .gif and .js are intercepted.
The deployer element can be used to deploy apps cluster wide.
Currently the deployment only deploys/undeploys to working members in the cluster
so no WARs are copied upons startup of a broken node.
The deployer watches a directory (watchDir) for WAR files when watchEnabled="true"
When a new war file is added the war gets deployed to the local instance,
and then deployed to the other instances in the cluster.
When a war file is deleted from the watchDir the war is undeployed locally
and cluster wide

3just make sure your CLASSPATH includes cloudscape.jar. Not just the path, but also the jar filename.
There is also a jre/lib/ext path in your java installation where you can dump your jar file so it will automatically be seen when you run your program. -

When adding fonts where SHOULD they be placed
It seems that fonts can be added to the two font folders as well as Font Book. I like to keep related items together, but fonts in the system library cannot (?) be put into font book, and if fonts are added to the system library what good is Font Book? Also what fonts are necessary in the system font list? It seems that the foreign language files could be deleted - or not?
Every font in system font is necessary, that's why they are in system font.
For managing fonts, just use font book, and let the system fonts as they are. Font book also just handels the Library Font and Personal Font folder.

Where to put unattend.xml when using create task sequence media
SCCM 2012 R2.
I created a capture task sequence media to a flash drive. I noticed the capture media does run sysprep even though it is not located on the flash drive. Where do I put my customized unattend.xml for sysprep? Does it go in c:\sysprep
There is no documentation on this that I can find.sysprep doesn't use an unattend.xml file so you don't put it anywhere. You supply a custom unattend.xml during the deployment task sequence which in turn is delivered as part of the TS for use by WIndows Setup (which is what actually uses an unattend.xml
file). Task Sequence media has nothing to do with sysprep either. I think you may be confusing sysprep with Windows mini-setup. sysprep is the process of generalizing a system generally preparing it to be captured. Windows mini-setup is what runs the first
time a syspreped system is booted. They are two different things.
You *can* place an unattend.xml file the image for use by Windows mini-setup -- the locations mini-setup will look for this file are detailed at
http://technet.microsoft.com/en-us/library/cc749415(v=WS.10).aspx . But that is rarely done anymore with task sequences because you generally want to dynamically inject an unattend.xml
file into the process instead of statically placing one in the image -- that defeats the purpose of having a generic reference image. This is done by configuring the Apply Windows step in a deployment task sequence.
Still, that begs the question posed by narcoticoo. Your reference image(s) should be hardware agnostic, built on a VM, and automated. What you are doing will cause you pain in the long run.

Errors when using tomcat and netbeans combo.[Solved]
Hi I'm trying to set up a netbeans/tomcat7 development environment for servlet development.
I have tried this on 2 machines without any success.
The steps I have followed are as follows.
First I installed tomcat7 and netbeans from using pacman, then to be able to configure tomcat from netbeans I made the config files write permission 777, as it's just a development server security is not an issue.
From there I started up netbeans started a new project and set the server to tomcat and pointed the Catalina home dir to /usr/share/tomcat7.
When I try to run the example jsp project I get the following error:

Last edited by darkclown (2011-12-01 05:15:23)From the error, it appears that there is no JDK installed - only a JRE, could that be the case? If you do have a JDK installed, then Tomcat is not finding it.
I would also not run this on the openJDK, in case you are doing that. I would use the proprietary Oracle/Sun JDK. It's in the AUR, or simply download it from Oracle.
I was not even aware that netbeans and tomcat are available from pacman. I always "install" those myself manually (i.e. unpack them into a folder). They are simply Java apps that can be installed anywhere, as long as you point them to a valid JDK. -
ConnectException when using Tomcat 4.1
Hi,
I'm trying to run my web application with Tomcat 4.1 (until now I worked with Tomcat 3.2, and didn't have problems).
In my application I have an applet that reads from a file (the file is located on the web server.)
When I try to do it (using Url.openStream()) I get:
java.net.ConnectException: Connection refused.
I guess I have to configure some kind of permissions in the tomcat configuration files or something like that, but I didn't find anything.
(In my Java policy tool I made sure to give java.security.AllPermission, but I'm not sure that it's connected).
Can you please help me?...
Thanks,

// With a URL now available, try to esatablish a read
// mechanism and read in the file as a series of String lines
try
InputStream is = sourceUrl.openStream();
InputStreamReader isr = new InputStreamReader (is);
BufferedReader d = new BufferedReader (isr);
return (readLines(d));

N97 - Where are emails synchronised to when using ...
I noticed today that Nokia PC Suite allows synchronisation of emails (it didn't for my old N95). Having gone through the wizard and then synchronised the phone I can't actually see where these emails might have been placed on the phone.
I use Profimail as my phone client and this is setup to handle my personal email using IMAP. So there's no account setup on the phone for the built in Nokia email client.
So this issue is about copying of work emails, not my personal emails. The MfE folder is empty, the sync log files don't mention anything about failing to copy over the emails. So where would I see these please?
Edit...
Sorry, just to add that I only want to view the emails, not reply to them.
Message Edited by hyde_tds on 01-Sep-2009 12:37 PMI'm afraid my question hasn't really been answered. I'll be more specific. In Camera Raw, I set Exposure to +0.80, then click Open Object to open the file as a Smart Object in Photoshop CS4. Does that embed an "Exposure=0.80" instruction somewhere in the PSD file? I think the answer is "yes," that a Smart Object consists of the RAW camera data along with all the Camera Raw settings, including the Exposure setting.
But if that is the case, then why does Camera Raw create an XMP file next to the PSD? It seems to me that the XMP file is unnecessary, that it contains information redundant with the settings stored in the PSD, and that it gets out of sync with the PSD as soon as I double-click the Smart Object layer in Photoshop and set Exposure to anything other than +0.80. I find the presense of the XMP file to be terribly confusing.

Where to put firmware files when using hwdetect
I am using release 0.7.1. AFAIK in 0.7.1 hwdetect is used instead of hotplug. Where hwdetect expect to find firmware files? In the case it can be changed, please tell me where.
it's udev that is handling firmware files, and I placed mine for atmel wireless in /lib/firmware works fine

Where should I start from to use HP4145B with LabView?
I am not familiar with LabView, but I have to set up LabView to make it work with HP4145B.
I downloaded the driver from NI, placed it at the correct directory, and can see VI's in function palette.
Also, when I run MAX, it shows "Instrument 0" under GPIB0.
When I click on "Scan for Instrument", it says something about IDN query, but now I know HP4145B is too old to understand IDN query.
I saw a lot of posts that say they can write to the instrument but cannot read.
However, I don't even know how to test whether my labview can write to 4145B or not.
My questions are....
1. 4145B manual says it has "ID" code.
I tried testing it by using "Interactive Control"
And I got this by NI Spy

There are four LED's on the front panel of HP4145B.
It shows status of HP4145B whether it is talker or listener.
LED changes properly to my command. (So I don't think there is any problem with harware connection)
But, I still get nothing but EABO error when I want to read something.
What am I doing wrong?
How can I test "ID" code?
(I do not have ultra-fast typing speed so I think I gave 4145 enough time to respond before I typed new command)
2. I tried to use driver I downloaded from NI.
Other posts say that people used "HP 4145 Example.vi" for testing.
However when I put "HP 4145 Example.vi" on the block diagram, I cannot run it.
How do I test with "HP 4145 Examble.vi"?
3. I tried testing other vi's such as "HP 4145 source setup.vi".
I put that vi on the block diagram window, added constant of 17 to GPIB address,
and other constants to other inputs and run it.
A new window popped up, so I ran it again.
However it does not seem to work since I see no change when I go into source set up menu directly from HP4145 front panel.
Again, LED indicator changes to LTN(which means HP4145B is in listener mode) when I run vi.
What would be the problem?
I'm experiencing a lot of trouble with this HP4145B, and I know too little to solve this by myself.
Somebody please help me with this.
Thanks in advance.My 4145b uses address 17.
I checked switch setting on the backpanel of 4145b and CRT on the front panel says "HPIB(17, COMMA, EOI)". Also, when I change address to 16 and execute vi file, it gives me an error message of "HP 4145 Define Channel; HP 4145 Send Message"
When I change back to 17 and execute, error message disappears(and no more error message comes in when I send command to 4145b), but nothing happens on 4145b.
As I said eariler, LEDs on 4145b seems to be saying that 4145b understands basic command such as "change to listener" or "change to talker".
In addition, when I try to read from 4145b from "HP4145 example.vi", for example by clicking on "Display Graphics and Plot" and execute, I get error message "HP 4145 Take Measurement; Wait for Interrrupt (GPIB)". However, reading is not the problem to think right now because I don't even know how to read.
I have Newport 1830-C with me, and I checked this instrument with same GPIB-USB-HS and same PC I am using with HP4145b.
It works with 1830C. Therefore, it doesn't look like there is something wrong with my PC and GPIB-USB-HS.
Anyway, thank you for your attention.
