Pass a variable from JSP to embedded Script
I can't seem to find a way around this. Please help.
I need to get the value of "item.likes" from the JSP page and put it into the embedded Script.
Can I do that ?
Nothing I came up with worked, and I found nothing on the Internet. I searched for a lot of things. Is the only way to just implement that JSP page as a servlet ?
Please see code below
thank you !!

<sql:setDataSource var="profileDS"
url="jdbc:mysql://localhost/test"
driver="com.mysql.jdbc.Driver"
user="xxx" password="xxx" />
<sql:query var="profileQuery" dataSource="${profileDS}">
SELECT likes
FROM profiles where likes=?
<sql:param value="${param.likes}"/>
</sql:query>
<c:forEach var="item" items="${profileQuery.rows}">
c:out value="${item.likes}"/>
<%
String dd= request.getAttribute("item.likes");
out.write(dd); //does not work here ... should print out the value of item.likes
%>
</c:forEach>
Some funny scooping with forEach. But if you put a "<c:set var="item.likes" value="${item.likes}" scope="request"/>" first inside the loop it is possible to use that value for your script. But using your sample the printout gets funny. All script output first and then the EL-created out.
Hopes this helps you anyway.

[SOLVED] Pass Environment variables from PKGBUILD to .INSTALL script
Hi everyone,
I am trying to modify the grub2-efi-bzr (http://aur.archlinux.org/packages.php?ID=38369) package making some changes in the PKGBUILD and the post-install script. I want to pass few environment variables from the PKGBUILD to the install script. How do I do that?
Some code from the PKGBUILD
_bzrtrunk="lp:grub/grub2" # GRUB2 BZR Main Trunk
# _bzrtrunk="lp:~skodabenz/grub/grub2-bzr-exp" # GRUB2 BZR Experimental Branch
_bzrmod="grub2"
if [ ${_bzrtrunk} = "lp:~skodabenz/grub/grub2-bzr-exp" ]
then
_bzrmod="grub2_exp"
pkgver="exp_${pkgver}"
fi
# grub-extras bzr repo locations
_bzrtrunk_zfs="lp:~skodabenz/grub/grub2-extras-zfs"
_bzrtrunk_lua="lp:~skodabenz/grub/grub2-extras-lua"
if [ "$CARCH" = 'i686' ]
then
_EFI_ARCH=i386
elif [ "$CARCH" = 'x86_64' ]
then
_EFI_ARCH=x86_64
fi
# _EFI_ARCH=x86_64 # Uncomment if you want to override the if condition for _EFI_ARCH above, incase the EFI ARCH does not match the Linux Kernel ARCH.
# $CARCH=x86_64 and _EFI_ARCH=i386 requires gcc-multilib with lib32-glibc installed in the system.
# I do not know about $CARCH=i686 and _EFI_ARCH=x86_64
if [ ${_EFI_ARCH} = "i386" ]
then
pkgver="${pkgver}_x86"
_trns_name="grub2_efi_x86"
elif [ ${_EFI_ARCH} = "x86_64" ]
then
pkgver="${pkgver}_x64"
_trns_name="grub2_efi_x64"
fi
Now the post-install script needs the values of _EFI_ARCH and _trns_name env variables. I do not want to copy the if statements to that script as these are decided at compile time but needed while setting up grub2-efi. This is due to the fact that EFI-ARCH need not match the Linux Kernel ARCH. How do I do that.
Code from the post-install script
${_trns_name}-install --root-directory=/ --no-floppy --recheck --debug
cp /usr/lib/${_trns_name}/${_EFI_ARCH}-efi/lua.mod /boot/${_trns_name}/
cp /usr/lib/${_trns_name}/${_EFI_ARCH}-efi/zfs.mod /boot/${_trns_name}/
cp /usr/lib/${_trns_name}/${_EFI_ARCH}-efi/zfsinfo.mod /boot/${_trns_name}/
cp /usr/lib/${_trns_name}/${_EFI_ARCH}-efi/unifont.pf2 /boot/${_trns_name}/
cp /usr/lib/${_trns_name}/${_EFI_ARCH}-efi/ascii.pf2 /boot/${_trns_name}/
${_trns_name}-mkimage --verbose --directory=/usr/lib/${_trns_name}/${_EFI_ARCH}-efi --prefix="" --output=/boot/${_trns_name}/grub2.efi --format=${_EFI_ARCH}-efi ${_EFI_APP_MODULES}
Thank in advance.

Don't rely on %foo% existing -- it won't after the first build and this will prevent the PKGBUILD from being reentrant. I would use something like this (untested):

Your code works except for 1 problem in the install script I want
export __EFI_APP_MODULES="${_EFI_APP_MODULES}" (the passed ${_EFI_APP_MODULES} value should again come inside double quotes).
right now
export _EFI_APP_MODULES=ata part_gpt part_msdos fat ntfs ntfscomp ext2 iso9660 udf hfsplus fshelp normal chain linux ls search search_fs_file search_fs_uuid search_label help loopback boot configfile echo efi_gop efi_uga xnu xnu_uuid lvm
which is equivalent to
export _EFI_APP_MODULES=ata
I want
export _EFI_APP_MODULES="ata part_gpt part_msdos fat ntfs ntfscomp ext2 iso9660 udf hfsplus fshelp normal chain linux ls search search_fs_file search_fs_uuid search_label help loopback boot configfile echo efi_gop efi_uga xnu xnu_uuid lvm"
How to do it with sed since sed already uses double quotes? -

Passing a variable from jsp to javascript
Does anyone know of a tag library or something else which allows one to do the equivalent of:
<jsp2js jspVar="${myJspVar}" jsVar="myJsVar" />where the result would be a javascript assignment statement in the html which sets myJsVar equal to the value of myJspVar. I know there are some simple solutions for things like strings, ints, etc. but I have some multi-dimensional arrays, and would prefer not to have to code out something like this manually.I'm pretty sure that won't work for arrays, (much less multi-dimensional ones).
EDIT: I did a little more looking and it seems that JSON or DWR will be able to suit my needs fairly well. -

Is it possible to pass a variable from a shell script back to an Automator action?
For instance, if I assign a value of foo to $var1 in my shell script how would I retrieve/pass that value in the next Automator action. I see that there is a variable called "Shell Script" but I can't any information on how to use it.red_menace,
Thanks but I still don't understand how to pass a single value that was set in the UNIX scipt back to Automator has a variable.

How can I pass a variable between JSP and Role Form
I need to pass a variable from (a copy of) applicationmodify.jsp to the IDM Role Form so that the variable is available within the Role Form at display. We've tried getAttribute and setAttribute modifying both the Role Form and the applicationmodify JSP and can get the form to the role form but not accessible but have had no other success. Has anyone had any success in doing this? Any suggestions would be appreciated.
if by _root level you mean you're loading something into
_level0 you can't won't be able to use the localconnection. the

LoadVars-using send to pass a variable from flash to php
For the life of me, I've tried everything:
I've researched LoadVars on Adobe forum, used David Powers'

$HTTP_POSTVARS but I keep getting this same error. any advice
please?

How to pass a variable from one class to another class?
Hi,
Is it possible to pass a variable from one class to another? For e.g., I need the value of int a for calculation purpose in method doB() but I get an error <identifier> expected. What does the error mean? I know, it's a very, very simple question but once I learn this, I promise to remember it forever. Thank you.
class A {
int a;
int doA() {
a = a + 1;
return a;
class B {
int b;
A r = new A();
r.a; // error: <identifier> expected. What does that mean ?
int doB() {
int c = b/a; // error: operator / cannot be applied to a
}Thank you!elaine_g wrote:
I am wondering why does (r.a) give an error outside the method? What's the reason it only works when used inside the (b/r.a) maths function? This is illegal syntax:
class B {
int b;
A r = new A();
r.a; //syntax error
}Why? Class definition restricts what you can define within a class to a few things:
class X {
Y y = new Y(); //defining a field -- okay
public X() { //defining a constructor -- okay
void f() { //defining a method -- okay
}... and a few other things, but you can't just write "r.a" there. It also makes no sense -- that expression by itself just accesses a field and does nothing with it -- why bother?
This is also illegal syntax:
int doB() {
A r = new A();
r.a; // error: not a statement
}Again, all "r.a" does on its own is access a field and do nothing with it -- a "noop". Since it has no effect, writing this indicates confusion on the part of the coder, so it classified as a syntax error. There is no reason to write that. -
Is it possible to pass a variable from one animation to another?
I have multiple animations on the same page. I need to pass a variable from one to the other.
Animation One has this:
sym.setVariable("myVarOne", 1);
Animation Two has this:
var myVarOneInTwo=Edge.getComposition("EDGE-12345678").getVariable("myVarOne");
Seems like it should work, but kinda hard to tell. I put in:
console.log("myVarOneInTwo = " + myVarOneInTwo);
But I get: Javascript error in event handler! Event Type = timeline
So it seems that it doesn't like getting a variable from another animation.
Is there a way to pull a variable from one animation into another?Sorry also had to fix this:
var myVarOneInTwo=Edge.getComposition("EDGE-12345678").getVariable("myVar One");
To this:
var myVarOneInTwo=Edge.getComposition("EDGE-12345678").getStage().getVariable("myVar One"); -
How to pass javascript variable to jsp function
i want to check which table header (that is <th> in html )is clicked and based on that a jsp funtion do a query in database and should show records in sorted way according to which column head is clicked.
Table is created in html.
My function is
Vector varray = workcaseid.getWorkcaseId(Long.parseLong(MasterAccountNumber),SelectedColumn);
<table border="1">
<th ><label onClick="<%SelectedColumn="workcase_id";%>">Workcase Id</label></th>
<th><label onClick="<%SelectedColumn="status_id";%>">Status</label></th>

varray = workcaseid.getWorkcaseId(Long.parseLong(MasterAccountNumber),SelectedColumn);
just tell me whether it is possible to pass javascript variable to jsp variable or not.i can do it by using hidden input type,using form and submit button. -
Passing a variable from a movie clip to the main timeline
Hi,
I'm having trouble passing a variable from a movie clip in my
flash file to the main timeline.
I have a movieclip with the instance name IntroNav which
contains several buttons. Clicking a button sets the variable
"page" to a specific name, i.e. page = "home"
However, outside of the movie clip, on the main timeline I am
unable to call this variable, and "page" seems to have no value.
Can anyone tell me why this is and how to solve it?
ThanksUmm, yes ... declare your variables correctly.
var page:String = new String(); //proper complete
var page:String; //strict typing
var page:String = "home"; //stirct typing with value
declaration
Do not declare the variable in your buttons, you would have
to do so in every button and be constantly resetting the value.
Declare it on the main timeline at the lowest level. You do not
need to use it as a _global, you just need to resolve your path
issues. You can 'set' the variable value from a button, without any
problem, but you have to call to the variable correctly.
You do not 'name' a variable as "_root.page" , the '_root'
refers to the lowest level of the SWF or the main timeline, as does
a call to ' _level0' (that's a zero). If the variable is declared
on the main timeline, and you're calling from the MC/button or
anywhere you can refer to the variable by calling to it by
the proper path of '_root.page'
To set the variable from any of your button/MC instances
call:
_root.page = "value"; OR _level0.page = "value";
But you must have the varibale declared on the main timeline,
and only once and the playhead should be stopped or it will reset
the value to the default upon looping.
