Non-trivial selectManyCheckbox example
Hi
Does anyone know of a good tutorial or complete working example of how to use h:selectManyCheckbox ? All the examples I can find on the web are quite basic - either just JSF fragments, or using simple hard-coded individual f:selectItem tags.
I would love to see a fully working example using a list or array of values from a backing bean, a setter for the user's checked checkboxes, maybe a converter for the values, and all the Java code of the backing bean.
If you have a non-trivial working selectManyCheckbox (either Sun "h" or MyFaces Tomahawk "t" will do) please please post here.
Thanks very much
Matt West.
It's fairly straightforward:<h:selectManyCheckbox value="#{myBean.selectedItems}">
<f:selectItems value="#{myBean.selectItems}" />
</h:selectManyCheckbox>MyBeanprivate List < T > selectedItems;
private List < SelectItem < T, String > > selectItems;
// with default getters and settersWhere T represents the object type to be selected and String should represent the label of the checkbox.
Note: remove spaces around the < and the >, because the parser of this forum doesn't correctly parse nested parameter types.

How to connect one SAP system to Non-SAP system(Example:Window's7)?
Hi Experts,
In general, One SAP system can connect another SAP system through RFC.How to connect One SAP system to Non-SAP system(example:window's 7) and is it possible through RFC?
Thanks and Regards,
NageswarHello Wolfgang Schaper,
Thank you so much for quick response.
As you told I am trying to work with BRFplus/DSM to call decision services from nonABAP systems,so I tried with RFC.But it is not possible as you told.
Please give any solution Without using Web Services, is there any ways to connect from SAP system with the Non-SAP Systems. -
Glazedlists - can't make filter work in non-trivial app
Hey, has anyone here used glazedlists in a non-trivial application?
https://glazedlists.dev.java.net/
They're really nifty - or would be, if I could get them to work in my own appliction. (In a nutshell, it's a table that is smart, and can do on-the-fly filtering and sorting without you having to code it. Way cool).
The demo works for me, from the jar as well as when I build it from source. I take the demo code and paste it (with trivial modifications to make it fit) into my application, and now the filtering doesn't do anything - and staring at the code, I havn't been able to spot any significant differences between my code and the demo (other than those required to make it fit in - package names and such). I suspect there's a threading or interface issue, where my code is listening for something and not passing it along (or something like that), but I don't have the experience to say for sure. I'm not posting code here because it's big, and mostly non-related to the problem at hand I suspect. ( I think it's something subtle, and not my cut&paste, because the demo code is small - a few screens for the whole app)
Any swing gurus have any pearls of troubleshooting wisdom? I'm gonna keep beating on it, but thought I'd see if anyone had some insight on this...

You can't use an iPad app on your Mac. The operating systems on your MacBook and your iPad are completely different, so apps designed for one will not work on the other. You'll need to see if the developer of the app offers a version for Mac OS X as well, in which case you'll probably have to purchase it separately.

Non-trivial Database editing examples
Hi everyone,
I'm searching for examples of database editing and setting properties that are more complex than the ones that ship with LabWindows/CVI. As far as I can tell, these don't even edit the database, they just manipulate aliases and parse through the different clusters/frames/signals, despite being titled "Managing Databases". Anyone out there know where I can find this kind of info? Thanks!
- Brandon
EDIT: I'm using the XNET APIThose examples do edit a database, the database just happens to be in memory instead of on disk. To be honest whenever I need to actually edit a DBC file I usually resort to Vectors database editing software which runs without needing any particular hardware or software license.
But if you are strickly in the XNET world, import the DBC, then use the "Database Editor" to edit the XNET database. This is saved as an XML but contains much of the same information as DBC. You can also programatically import a DBC to use in XNET if you periodically get updates.
My conversion library does this in the examples.

Non-blocking SSLEngine example
Since the example of using SSLEngine with non-blocking IO that comes with Java is quite limited, I have decided to release my own for anyone who wants to see how I solved the various problems that you must face. The example is designed to be a generic non-blocking server that supports SSL.
This is only meant to be an example, as I wrote this mostly in order to learn how to use the SSLEngine, and therefore has certain limitations, and is not thouroughly tested.
You can download the file at: http://members.aol.com/ben77/nio_server2.tar.gz
Here is also the code for SecureIO, which is roughly analagous to the Java example's ChannelIOSecure:

}That's the reason for checkHandshake(), it is called on every read and write and detects a new handshake and configures the setup properly. As far as the server requesting a new handshake, I did not put that in. It would be simple enough though, you would just need to call SSLEngine.beginHandshake() + then call checkHandshake().
Also, my echo server example had a bug, I forgot to call bu.flip() before queueWrite(), so I fixed that, as well as adding an onConnect method that is called when a connection has been established. The new version should be up at the origional address shortly. -
Looking for an alternative to an enum (or any non trivial type)
Hi. I am making a class to manage geometric points, as in [x, y, z]. some languages, such as scripting language 'adobe actionscript' support certain special values such as NaN (or 'not a number'), and I can do things such as
var _some_var:Number = Number.NaN;
the previous sentence is something like assigning null to a pointer. NaN is not a valid value, so I can not operate with a var that has nan as a value.
I want to do something like that in my class, but I can not use a number value and then say, 'this value is never gonna happen by itself, so if the var has that value is because is in nan state. for any value that I choose, if is a valid value, will be enough
to consider it as an invalid alternative. instead of that, the vars are handled in pairs, so for each numeric coordinate, such as x, there is also a bool that says if the numeric value is defined
in each point, there are the x, y and z coordinates, plus defx, defy and defz.
the constructor is something like
point() {
x= 0;
y= 0;
z= 0;
defx = false;
defy=false;
defz=false
and since all vars are private, I use accessors such as
setX(double _x) {
x = _x;
defX = true;
so how do I assign a NaN to a var that has already a value?, or, how do I set the var 'defX' to false again?
since setX(_some_value) is the same as x = _some_value, the idea would be that I could write something like
setX(NaN), and that would 'undefine' X.
since I can overload functions, and create functions with different prototypes for different types of values, even though the functions are called the same way, that's what I am doing.
I had two choices: the first one is (copy paste from my file)
//#ifndef _nan
//#define _nan
//#define NaN "NaN"
//#endif
not the one I chose because it does not seem better than my second choice (that's why it appears as a comment), or does not solve the problem I have with the choices I have thought so far:
(in file 'especiales.h')
#ifndef _especiales
#define _especiales
enum EEspecial {NaN};
#endif
and in the file for the point definition (as inline functions)
void setX(double _x) {
x = _x;
defX = true;
void setX(EEspecial _e) {
if (_e == NaN)
defX = false;
else
throw coordIndefException();
double getX();
bool definidoX() {return defX;}
it works, it does not throw an error or there are no syntax problems; but there is a problem in my head. In the previous sentences there are two functions, one that takes a numeric value and sets it in x, and sets x as defined. on that receives not a numeric
value but a special value, that if it turn out to be nan, will unset the x var, and set it as undefined.I checked it with these simple lines:
geometriaPunto _ensayo;
try {
_ensayo.setX(NaN);
cout << _ensayo.getX() << "\n";
} catch (exception _e) {
cout << _e.what() << "\n";
this works fine. if I place a 0 in setX, it will print 0. if I place a NaN in the parenthesis, it will write the exception name. This works fine. But as far as I know, all basic var types, and all enums, also have implicit conversions to numeric values.
so even though it works here, as I understand, telling it setX(0) is the same as setX(NaN) (which would be the implicit conversion of NaN, since is the first value in the enum). none of those are double (because I did not wrote it as setX(0.0) ), so my guess
is that even though it works here, it was just luck, and some other c compile may understand it different, since there is not much difference between function_name(int) or function_name(enum_type)
what would be the best way, most clear way to overload 'setX()' so it does accept a type that can not be confused with a numeric value, yet it does not make my code way more obscure and does not create ambiguity?
tnxthis is the last post I will make on this thread, as I find your answers useless and I already have what I need, but concerning your answers:
"You said it worked for you in your 'adobe actionscript' code - why wouldn't the same technique work in C++ code? Number.NaN is a Number value, and it doesn't prevent you from doing operations in a var that holds that value - but that didn't
seem to concern you before."
have you ever worked with actionscript or did you just post because you had to post anything. yes, I can assign NaN to a numeric var in actionscript, just like I can assign null to a pointer. null is a value (0), if I add something to a var that has null,
it will not have null anymore, if the compiler or the executable don't verify this behavior that should throw an exception. In actionscript, if a var has nan and I add something to it, it will still have nan, because nan is not a value, is a state, and probably
actionscriopt also handles numeric vars with some other types of vars, to make these kind of validations. If I add 1 to garbage, I will still have garbage, and if I choose a random value to be chosen as nan, I or anybody else can not assure this value will
not be the result of a valid operation
2. "Is your question about C#, and not C++? If it is, you are in the wrong forum."
why do you ask, did you see the previous sentences written in c#, or do you still have to answer crap if you don't answer something related to the question. if somebody has been writing things in other languages (including java or the same actionscript,
which support that kind of behavior for properties and accessors), seems logic that I want to maintain that programing style, which will help somebody who also has been writing in those languages and then tries to read this new source, written in c++ -
Non-Cumulative keyfigure example
Hi all,
To test for non-cumulative keyfigures I have modeled a keyfigure noofemployees and below is my model
<b>Infocube has following characteristics, timecharacteristics and keyfigures</b>
Charteristics: Companycode
TimeChar: 0calmonth
Keyfigures: salesrevenue and noofemployees
<b>My infosource has following infoobjects</b>
Companycode,0calday,salesrevenue,nofoemployees
In update rules, I wrote a formulae(0calmonth2) to convert 0calday to 0calmonth.
I want to generate a report to know for every company, its monthly sales and number of employees.
I created numberofemployees as a cumulative keyfigure with exception aggregation as Maximum(to get the maximum number of employees in one month instead of aggregating the values). I don't know if I am doing something wrong, but my keyfigure noofemployees is aggregated for each month.
Please let me know if I created the keyfigure noofemployees correctly.
thanks,
Sabrina.Hi Sabrina,
A non-cumulative keyfigure can be modeled in BW either using
-a cumulative keyfigure that stores the non-cumulative value changes of the non-cumulative keyfigure or
-Two cumulative keyfigures which represent the inflow and outflow values of the non-cumulative keyfigure.
The keyfigures used to define the non-cumulative keyfigure - keyfigure for non-cumulative value change or keyfigures for inflow and outflow - should themselves be cumulative keyfigures and have the following properties.
Standard aggregation -> Summation
Exception aggregation -> Summation
So as per the definition you first create a cumulative Key figure to capture the non-cumulative value changes of the non-cumulative keyfigure.Say ZKF1 and assign following properties:
Aggregation: Summation
Exception Aggregation:Summation.
Now create a Non-cummulative Key Figure say ZKF2 and assign following properties:
Aggregation: Summation
Exception Aggregation:Last Value
Non Cummulative Value Change:ZKF1.
This will give you non-cumulative keyfigures "number of employees" correctly.
Hope this helps.Please grant points if it solves your purpose.

Convert tab separated text to non-trivial xml. (pwsafe -- KeePassx)
I'd like to take the output of `pwsafe --exportdb > database.txt` and convert it to a KeePassX XML friendly format (feature request in pwsafe).
I found flat file converter but the syntax is beyond me with this example. Solutions are welcomed.
More details
Here is the pwsafe --> KeePassX XML translations. The pwsafe export is simply a txt file with 6 fields (the first field can be ignored):
uuid= doesn't translate

passwd= entry>password
notes= entry>comment
Example txt file for conversion (exported from pwsafe):

Last edited by graysky (2015-06-14 18:27:17)It seems that ffe does not work quite well with tab/space separated list (at least I was not able to get it working). However you can use sed to replace tabs with commas:
sed -e "s/\t/,/g" input.txt | ffe -c pwsafe.rc -s example.txt -l 2>/dev/null
and this is pwsafe.rc
structure pwsafe {
type separated , *
output group
quoted
header first
record line {
field uuid * * noprint
field title
field title * * entry
field username * * entry
field passwordd * * entry
field comment * * entry
output noprint {
data ""
no-data-print no
output entry {
data " <%n>%t</%n>\n"
no-data-print no
output group {
file_header "<!DOCTYPE KEEPASSX_DATABASE>\n <database>\n"
record_header " <group>\n"
data " <%n>%t</%n>\n <entry>\n"
record_trailer " <entry>\n </group>\n"
file_trailer "</database>\n"
no-data-print no
If you are not bound to ffe, maybe it is easier to use a python script which is simpler to modify and it is more flexible. Something like the following should work:
#!/usr/bin/python
import sys
from xml.dom import minidom
class Converter(object):
def __init__(self, filename):
self.url = filename
def convert(self):
inp_f = open(self.url, 'r')
data = inp_f.readlines()
inp_f.close()
# xml document model
doc = minidom.Document()
root = doc.createElement('database')
doc.appendChild(root)
for line in data:
if '"' not in line:
continue
fields = line.split('\t')
if len(fields) < 6:
continue
# uuid = fields[0].strip('"') # unused
group = fields[1].strip('" ')
name = fields[2].strip('" ')
login = fields[3].strip('" ')
passwd = fields[4].strip('" ')
notes = fields[5].strip('" \n')
group_node = doc.createElement('group')
root.appendChild(group_node)
# <group>
group_title_node = doc.createElement('title')
group_node.appendChild(group_title_node)
group_title_node.appendChild(doc.createTextNode(group))
# one <entry> per <group>
entry_node = doc.createElement('entry')
group_node.appendChild(entry_node)
# <entry> -> <title>
entry_title_node = doc.createElement('title')
entry_title_node.appendChild(doc.createTextNode(name))
entry_node.appendChild(entry_title_node)
# <entry> -> <username>
entry_uname_node = doc.createElement('username')
entry_uname_node.appendChild(doc.createTextNode(login))
entry_node.appendChild(entry_uname_node)
# <entry> -> <password>
entry_passwd_node = doc.createElement('password')
entry_passwd_node.appendChild(doc.createTextNode(passwd))
entry_node.appendChild(entry_passwd_node)
# <entry> -> <comments>
entry_comment_node = doc.createElement('comment')
entry_comment_node.appendChild(doc.createTextNode(notes))
entry_node.appendChild(entry_comment_node)
print('<!DOCTYPE KEEPASSX_DATABASE>')
print(root.toprettyxml(' ', '\n'))
if __name__ == "__main__":
try:
ifname = sys.argv[1]
except IndexError:
print("Input file name required")
sys.exit(1)
cc = Converter(ifname)
cc.convert()
NOTE: I'm assuming from the example you posted that every <group> node contains only one <entry> child node.
--edit[0]: corrected a typo in the python code (just realized that it is <comment> instead of <comments ) and made the parsing function more reliable

Non-trivial problem with NoClassDefFoundError
I want my Java 1.4.2. program to use the Apache Commons CLI library, version 1.2. Within Eclipse, I can get the program to use the org.apache.commons.cli 1.2 jar file (I just add the jar to the build path). However, if I export the program as a jar and run the jar under DOS or Unix, I get the NoClassDefFoundError. I tried to fix the command path, by creating a CLASSPATH environment variable. This didn't fix the problem. I tried to include the path using the -classpath option under the java command. This didn't fix the problem either.
A while ago, I was able to use version 1.1 on a Java 1.5 program (under Mac OS X).
So I am stumped. How should I proceed?
Thank You.NoClassDefFoundError can mean several things but one of them is that a .class file was found in the correct place but it didn't contain the expected Java class. For example, it has been renamed, or the directory structure doesn't correspond to the package structure.

A non-trivial typo in the man page for pthread_cleanup_push()?
On my Solaris 9 and 10 systems, the prototype of the pthread_cleanup_push() function is, according to the man page:
void pthread_cleanup_push(void (*handler, void *), void *arg);
Should it be
void pthread_cleanup_push(void (*routine) (void *), void *arg); ?
Alternatively, if both are correct, what are the differences between the two? I tried to use the first format to write some test code and got a bunch of syntax errors.Ditto for pthread_create():
int pthread_create(pthread_t thread, const pthread_attr_t attr,
void *(*start_routine, void*),void *arg); -
J2EE Engine Web Administration: 404 on /admin/j_security_check
Environment: sneak-preview from June (the latest version), running on a Linux machine.
I'm trying to run the SAP J2EE Engine Web Administration application - i.e. http://b3.lab:50000/admin/LoginForm.jsp .
If I use J2EE_ADMIN/ADMIN for the user/password, I get a 404 screen, for the URL http://b3.lab:50000/admin/j_security_check (The requested resource does not exist.
Details:
Go to main page of this application!)
Note that this is different from a wrong user or password - in this case I get a http://b3.lab:50000/admin/LoginError.html page with an "incorrect username or password" - which is the expected outcome.
Any idea if the application is supposed to work?
BTW - I'm getting quite a few exceptions on other apps as well. For example - the "PC-shop" -> browse -> printer -> click-any-printer gets the exception below:
java.lang.NullPointerException

TIA!

I'm popping up this questions, and raise
Is there any non-trivial J2EE example application that is deployed / can be "tutorially" deployed on the sneak preview Linux version? By non-trivial I mean that it has web, ejb and db portions? (which is pretty modest requirements, I think).
Thank you,

hi, I'm having a frustrating time... can anybody help?
I know VC++ fairly well in an amateurish way and I really don't understand how Java apps of any size work... do they use the application-document-view architecture which seems to underpin most VC++ projects? It is proving very difficult to find non-trivial Java apps unless they are way over my head... Where can I get hold of a basic Java application skeleton?
Also, no books online or otherwise seem to explain how you go about splitting things up into discrete classes and yet letting them communicate adequately with one another... or what is the "ancestor" or indeed "parent" of a component... is it a JFrame?... where is all this documented? Where are examples of larger apps? Of the process by which they are developed?
Also, because so much code is taken up with just getting on top of the GUI and the layout managers, programs of any significance seem to grow at a frightening rate meaning that you soon do in fact have to split things up...
And then you find a passing comment in a doc saying "keep your GUI code separate from the business logic"... OK, care to spend a bit of time on that?
Please somebody recommend an online resource...??

External Tables & Non English Characters
Hi
I am new to external tables, i wanted to know what i need to do to upload the data which is of non-English characters,
Example
i need to upload the data where the single file will have data for more than one non-english characters.
1. English
2. Chinese
3. Korean
let me know if any other alternative exists for the same.
Regards
YramHi,
a good reference for External Tables is the manual: http://download.oracle.com/docs/cd/B19306_01/server.102/b14215/part_et.htm
If they are in one file, you can upload them all at once. Important will be how the data is stored in the file (UTF-8, UTF-16). This information you should set in the external table by using the CHARACTERSET clause, see the manual.
Your database also needs to support these characters!
