Why wouldnt this work?
HI,
i created a jsp dynpage using the wizard in NWDS and in the jsp file that is created using the wizard, i have written something like this.
<html>
<head>
header
</head>
<body>
body
<% String str = "jsp dynpage" %>
</body>
</html>
as you can see it is a plain jsp file without any hbj tags.
when viewed in browser, it throws a compilation error in j2ee engine.
but when i remove the line "<% String str = "jsp dynpage" %>".. it works fine.. why arent the jsp tags working here.. any idea?
thanks
This is ususally how I call a method from with in a jsppage. Notice that there is an '=' sign at the beginning. Maybe this is important in your case.
<%<b>=</b>salesNumbers.getCurDatInOrd()%>
You java code sort of doesn't make sence to me. You are just filling a string.

why isnt this working im trying to connect a panel to a scrollpane the panel will contain several dozen text fields
the scrollpane shouls be about 350, 450 , but the pane is 350

I've been practicing some IPSec VPN scenarios, starting with the typical site-to-site VPN:
Router A
crypto map mymap 10 ipsec-isakmp
set peer 1.1.1.2
set transform-set myset
match address 101
access-list 101 permit ip 10.1.1.0 0.0.0.255 10.1.2.0 0.0.0.255
Router B
crypto map mymap 10 ipsec-isakmp
set peer 1.1.1.1
set transform-set myset
match address 101
access-list 101 permit ip 10.1.2.0 0.0.0.255 10.1.1.0 0.0.0.255
This works as expected. Traffic from 10.1.1.x on Router A gets picked up by the crypto map and sent to RouterB and vice versa. What is confusing me is a more advanced scenario where I'm tunnelling GRE over IPSec with OSPF (why? Because I can).
http://www.cisco.com/en/US/tech/tk583/tk372/technologies_configuration_example09186a008009438e.shtml
Everything works just fine, but I'm bothered by the ACLs being used in the example. I don't see how everthing should be working- OSPF is fat and happy, and if I ping one spoke from another spoke from a loopback interface, it works as well. In this case, is the network traffic being picked up by the Tunnel interface first, and all the crypto map sees is GRE traffic by the time the packets make it that far?Ian
You ask a question about the access lists and I believe that it will be easier to answer the question if we have the access lists to refer to. So here they are:
7206:access-list 130 permit gre host 14.36.88.6 host 14.38.88.40access-list 140 permit gre host 14.36.88.6 host 14.38.88.20access-list 150 permit gre host 14.36.88.6 host 14.38.88.102610:access-list 120 permit gre host 14.38.88.10 host 14.36.88.63620:access-list 110 permit gre host 14.38.88.20 host 14.36.88.6
3640:
access-list 100 permit gre host 14.38.88.40 host 14.36.88.6
one of the first things to understand here (and you briefly mention it in your post) is that they are running OSPF dynamic routing protocol over the tunnels. So each router sees the path to get to the other router as being through the tunnel. So when the 2610 wants to get to the 7206 it will send that traffic to the tunnel interface. The tunnel interface will encapsulate the original packet in a GRE header. So yes the only thing that the access list will see is GRE traffic.
Anything that goes through the tunnel (whether it be a data packet or an OSPF routing update) is encapsulated in a GRE header and the access list does not see the original data but sees only GRE.

}This code will not compile and should produce one of possible many compiler errors. The condition inside the if statement requires each condition to be independent of one another. e.g. (username == "yes" || username = "Yes" || username == "YES").
This also represents one of the most common errors presented to new comers. Equivalence of Objects such as Strings are compared using a method .equals() and not the term "==". The latter actually compares two Strings by the address stored in memory.
class runBy convention all Class names begin with a capital letter
Also it appears that the class run contains main method and an inner class in which itself contains a main method. I will conclude right here that you are biting off far more then you can chew. Start with the basics, e.g. Google for Java tutorials and start from "hello world" then make your way from there. Tackle one problem at a time and learn the concepts of the tutorial which will hopefully stay with you, as these fundamental concepts will be your foundation to development using the Java language.

Work-around The Whine: why does this work? And is it BAD?
Hello everybody, sorry to bring up The Whine again, but I was wondering if anyone can figure out why the following trick works to eliminate the noise.
Also, could doing this regularly (all the time, basically) potentially be bad for the system in any way?
This is the work-around I've been using:
1. Open Photobooth, then Force Quit that application (you must Force Quit rather than simply quit)
2. Put the Macbook to sleep, waiting a few seconds until the indicator light starts pulsing.
3. Wake up the computer.
Voila. That always does the trick, eliminating the whine until either the next time I boot up or the next time I open and quit Photobooth in the normal way.
I suppose force quitting may keep the processor slightly busy somehow?
Don't know...John P.,
You say that all the notebooks that you know of make
some kind of noise. How many notebooks is that? Not
trying to be a jerk or anything but it better be like
dozens and dozens to make this claim. I have heard
the exact opposite of this claim from users that have
owned a few notebooks as well.
Hi Jerome,
No problem... I'll clarify..
5 notebooks personally, so when I say "all notebooks that I know of", it's a true claim because that is exactly what I'm saying.
If this noise is caused by capacitor that is at some
miniature threshold then why does the noise go away
when said remedies are employed? Does the capacitor
get bigger? Doesn't make sense but I appreiate that
you want to reassure original poster.
Actually I may have misspoken--it may be called a "voltage regulator" and it sits directly West of the CPU and controller chip. They do make noise and from what I have been told and remember, they can dampen it w/ a capacitor but that's about it. It's just the nature of the beast for that type of component, I'm told.
What "I" think it may be is the power fluctuations, or lack thereof, in the Intel chip causing it--when you put a load on it, there's a power fluctuation because your CPU usage is going up/down a little bit, but when you're not doing anything it's very little it causes it to make a little noise. No big deal, but just as long as it's not blaring in your ear when you're trying to use your computer. My ZV6000 does the same thing, but it doesn't matter when you've got a load or not--seems to do it more when I have Cool 'n' Quiet enabled.
This is not right. I am sorry.
If this noise is normal then I'll take no MacBook.
You know it is being fixed apparently on the MacBook
Pros by motherboard replacement.
I never said anything about pro. I don't own one, nor have I used one. I can't say how profound in comparison to the Macbook (non pro) it is.
I'm sure if Apple thought it was a big enough problem, they would act either more quickly about it, but it's not stopping me from checking my e-mail or going on the Web. -
Filter as autoload trigger; why does this work?
In my efforts to use PS consoles more and CMD consoles less, I've been "porting" my environment over. One of the things I can't live without is my 'cd aliases'. I have several aliases like: "src=cd /d c:\src" (loaded in doskey). Separate
functions for each alias seemed kludgy, so after a bit of playing around, I came up the little module below to mimic the functionality. The function takes a look at the alias that invoked it and sets the location based on values in a hashtable.
Since the aliases are dynamically created and thus aren't available to trigger the autoload, I decided to add a filter to do the triggering (I could just import the module in my profile, but I try to keep my profile lean).
My thought was that I could type 'src' and if the module wasn't loaded, it would cause the autoload to happen which would override the filter 'src' with the alias 'src'. Typing 'src' a second time would actually set my location to my source directory.
When I tested the 'filter autoload' however, I was pleasantly surprised that not only did it autoload the module, but it did the set-location on the
first invocation.
My guess is that PS sees the command 'src' and when it's passed looks at the modules that can satisfy the command. Finding a filter named 'src' in CdAlias.psm1, it autoloads. Then PS, knowing that the needed module is now loaded, resolves 'src' against the
now-current environment, finds the alias, resolves that to Set-XLocation and we are off to the races. That said, I'm only guessing here, and since this seems like something that could be useful in other places, it would be cool if someone could confirm my
guess or explain what's really happening.
thanks,
K.
Note: This is the prototype, I will actually store the hashtable in the registry along with functions to edit the entries.

Uses the name of the alias used to call the function to look up
a path in the script-scoped dictionary 'xlocation' then sets
the location to that value.
.PARAMETER ChildPath
Optional child path, if passed it will be joined with the base.
.NOTES
Not sure why the filter trick works, but it does. Since src is my
most commonly used alias location, I can use it to auto-load. What
really confuses me is that it still sets the location to src the
first time I type it.

Why doesnt this work, its so simple
The following piece of code I guess should print "THEY ARE EQUAL" but it doesnt. I dont know why???????????? anybody help.
String check = new String("new���".getBytes("iso-8859-1"), "iso-8859-1");
for(int i =0 ; i< check.length(); i++)
if(check.charAt(i)=='���') System.out.println("THEY ARE EQUAL");
}You aren't comparing whether the two strings contain
the same data, you are comparing whether the two
references point to the same objects. Try it again
using the .equals() method to compare the contents of
the two strings instead of using ==.For the first time in my life have I seen DrClap err. So he is human too. amit234 is comparing characters and not Strings
I found the solution to your problem your the corresponding line in your code with this one and it would work
if(check.charAt(i)=='\u20AC') System.out.println("THEY ARE EQUAL");
happy coding -
Why does this work in MS SQL and not in Oracle
ALTER TABLE Stk
DROP COLUMN ComCode;
This BASIC statement works perfectly
in MS SQL, but after 2 hours now, it
simply refuses to work in Oracle,
although the syntax seems correct, I
get :
ALTER TABLE Stk
DROP COLUMN ComCode
ORA-00905: missing keyword
nullStop trying! Oracle simply does not support the DROP COLUMN syntax. A work around is:
CREATE another table based on the original table, minus the column you want to drop.
(CREATE TABLE new_table AS SELECT col1, col2 , ... FROM old_table)
DROP the original table.
(DROP TABLE old_table)
RENAME the new table the old table.
(RENAME new_table TO old_table)
Your have to manually add the constraints, if the old table has any.

Map map = new HashMap(); -why doesnt this work in jdk 1.8.1
Hi there,
I'm trying to use a hashmap like this below:
Map map = new HashMap();
map.put("Carrots", new Integer(12));
map.put("Potatoes", new Integer(30));
map.put("Onions", new Integer(15));
map.put("Apples", new Integer(40));
map.put("Cherries", new Integer(300));
the HashMap() does not exist in my API for some reason.
Can anyone tell me why this may be?
i'm using the hashmap with a stringtokenizer to search a text file line by line and increment how many times each keyword occurs.Sound efficient way of doing it?
cheers,do you mean jdk 1.1.8?
Map and the other Collections API were added in JDK 1.2. for JDK < 1.2, use Hashtable instead. -
Why does this work? (dmenu_run shell script...)
I'm very confused at what this is doing. dwm knowledge would help to understand my question. I don't understand how this script can take a font name with a space in it, the way dwm's default config does, and understand it as one argument.
#!/bin/sh
exe=`dmenu_path | dmenu ${1+"$@"}` && exec $exe
Before updating to a newer version of dmenu (where this is included), I had written my own dmenu_run script. Although I wrote it, I actually don't understand how this one worked either. It was a trial and error thing, and when I try to think it through I always conclude that it shouldn't work.
#!/bin/bash
IFS="\t" # (was actually a literal tab character in my script)
`dmenu_path | dmenu $*`
This does not work without redefining $IFS, so I figured that dwm is not somehow making sure that spaces are interpretted correctly. But by stopping spaces from separating arguments, shouldn't this cause huge problems for everything except the font name?
An example of how this would be called by dwm:
dmenu_run -fn -*-dejavu sans-medium-r-normal-*-12-*-*-*-*-*-*-*
(Note the space in the font name)
So what is going on here? I realize that my question is somewhat confusing. I'm happy to clarify anything that is confusing - I found it very hard to clearly ask this question.
Last edited by fflarex (2008-11-07 05:06:24)First off, sorry for all the shell-speak. This is a bit of an edge case, so it's sort of unavoidable. That said, I'll summarize what you need to know at the end.
The dwm version of the script uses $@ in double quotes. @ contains all the parameters passed to the shell, just like * does. The main useful difference is a special case: when double-quoted, $@ expands to the list of arguments, each as a single shell word. Double-quoted $* expands to the list of arguments as a single word delimited by $IFS. (Both variables expand to the list of arguments [with word splitting applied according to $IFS, hence your spaces problem] when unquoted.) Here's the logic flow:
1. dwm calls dmenu_run with the list of arguments specified in your config.h. It calls it directly, not running a command through a shell, so word splitting is never performed and spaces in values don't matter.
2. dmenu_run calls dmenu with the list of arguments it was given. It uses two shell tricks: first, quoted-@ to pass the list of arguments without word splitting. Second, the ${foo+bar} expansion syntax, which expands to bar if foo is defined, otherwise the null string (""). So it expands to the full list of arguments, each as a single word, only if arguments were passed (if $1 is defined).
What you need to know: You almost always want to use '"$@"'. Unless you want all your arguments as a single string, in which case you want '"$*"'. Other forms are practically useless.

After a big loss of out-pulled hair here is the code:
setInterval() calls getNewMess function but it happens
nothing with onNewMess function.
Instead, if i click refresh-button, it gives me result
correctly.evt.target._parent
is just using the event argument that is dispatched to and
therefore received by your listener function. It is dispatched/sent
by your button component instance. The event object from components
- in as2 - normally contains at least two properties. A type
property... in this case that's "click" , because its a click event
and a target property. The target property is a reference to the
component instance from which the event originated. It can be
particularly useful if you have one listener handling events from
many sources. So.....
evt.target._parent is referring to the container clip of the
instance that sent the event. i.e. The _parent of the button in
this case.
That's why I replaced it with t (=this) which is a reference
to the timeline that the button is running in. Now it doesn't need
to get that reference from checking the _parent of the evt.target
property from the evt argument. Which means the argument that the
newMess function receives can be ignored and its no longer reliant
on it. Sounds confusing but once you "get" it, it all makes sense.
Eventually, lol.
And of couse you don't need to have a button if you don't
want one. -
What did this do and why did this work?
I don't know if it was iTunes 10.5 or Internet Explorer 9, but I could no longer open the iTunes store. I uninstall Norton and still no luck. I was able to get into the store on my husbands computer also using windows 7, Internet Explorer 9, iTunes 10.5. So I decided to try the cmd_netsh winsock reset catalog enter netsh int ip reset.log enter. After I rebooted, I opened iTunes and the store opened right up and I was a shopping. Now can anyone tell me exactly what I did and why it worked? Just so I'll know in case it happens with another upgrade (and you know they will have one).

Essentially, you're resetting a registry key to its default settings. The settings changes you're reverting might have been inadvertent (due to damage to the key), or might have been deliberately made by a third party program that monitors internet usage (by instituting a Layered Service Provider on the PC). So making the change will possibly impact on the software that set up the LSP.
For more information about LSPs and their interactions with iTunes, see the following document:
