Hey!

How about using <mak:value expr='count(lapp.budget) == 0' /> ?


Greetings from across the table,

[Makumba-user] How to check if set is empty

[Viktor F. <vf...@gm...>]

Hello fellow makumbians,

I needed to check wether or not a set is empty. But I couldn't find a code
anywhere where I looked.
Can someone help me?
I tried
<mak:if test="not empty(lapp.budget)">
<mak:if test="lapp.budget != empty">
<mak:if test="lapp.budget not empty">
<mak:if test="lapp.budget is not empty">
<mak:if test="lapp.budget != nil">
<mak:if test="lapp.budget != null">

Also all possibilities with <> instead of !=, but nothing worked.
Any ideas?

Cheers,

Re: [Makumba-user] image thumbnails

[Stefan B. <ste...@gm...>]

A common need with maps is to zoom into details without needing to get
whole map onto the client side. This is usually done by resizing the
map into several zoom levels and slicing each level into small square
sections, "tiles". Those can then be easily viewed with a bit of
javascript. Openlayers (much like google maps) is most common
opensource piece of such Javascript.

It also allows (with a bit of tweaking) one to view georeferenced
antique maps overlaid over a recent map with adjustable transparency.

Tool to slice large map images into tiles:
http://www.maptiler.org/
Javascript for viewing such maps:
http://www.openlayers.org/
An example usage: http://openstreetmap.org

Hope it helps
Stefan

hmm i keep forgetting this one, as i very seldomly (if at all) get the

Re: [Makumba-user] tomcat/servlet/JSP hosting

[Manuel G. <man...@gm...>]

hi,

I think this is a good idea

http://www.arvixe.com/linux_web_hosting seems to be really cheap, I 
wonder if mysql space is really unlimited, if yes I think u should try it

maybe they offer trial period?


http://www.visionwebhosting.net/services.html

also offers a plan for 4$/month, with shared tomcat

the only problem I see is that if there's that strange mak bug with the 
class not found problem, then that may affect the whole tomcat and they 
may complain (btw: I still have the problem, also in Eclipse when it 
re-deploys locally, and on a standard tomcat when re-deploying a war 
when there were changes in mak, sometimes)


http://www.hostjava.net/

here u can try for 1$ for 14 days but they have limited disk space...but 
  unlimited mysql, whatever that means

[Makumba-user] tomcat/servlet/JSP hosting

[Cristian B. <cr...@cs...>]

hi

i am running a makumba production application in a Linux virtual server 
for 2 years now. however the trouble with Linux is that it needs updates 
to protect it from attacks.

so i now think that the winning strategy is not to use a Linux (virtual) 
machine provider but a tomcat provider, i.e. an internet provider that 
does not just support webpages, PHP and such, but also servlets and JSP. 
my ideal is to give a WAR and a database and the rest is up to the 
provider. this was actually part of the point with Sun designing the 
java servlet standard.

has anybody tried something like this? i found a number of them, but my 
database is at 10 gigs so some of them are useless because the disk 
space they allow is smaller than my db. would be good to know about them 
for other apps anyway.

for my purposes i found
http://www.arvixe.com/tomcat_jsp_java_servlet_hosting

http://www.oxxus.net/java-hosting/features.htm

i also found a more comprehensive list
http://www.servlets.com/isps/servlet/ISPViewAll

but i don't know how often it is updated.

i used google searches like java servlet hosting, jsp hosting, tomcat 
hosting, etc.

i currently pay 15  EUR/month, and i don't want to pay much more, say 25 
or so... otherwise i'd stick to updating linux...

Re: [Makumba-user] image thumbnails

[Risto J. K. <rko...@cc...>]

  Hi!

  Not sure how automatically you want it to be done, but for the BEST 
systems we have this little class that calls some other Java classes 
(like java.awt.Image) to do image scaling and cropping:

http://cvs.best.eu.org/karamba/public_html/WEB-INF/classes/org/eu/best/util/ImageUtils.java?rev=1.4


  Example of usage can be found here, on method processPersonImage which 
produces three differently scaled versions (200, 100 and 25 pixels) of the 
original image and writes them to the database:

http://cvs.best.eu.org/karamba/public_html/WEB-INF/classes/org/eu/best/GenericHandlerLogic.java?rev=2.21


  For further details, try consulting people who actually wrote this stuff 
(mainly Rudi and Jasper, I think).

Re: [Makumba-user] [ITD/Parade] Unable to surf public pages in maja-k

hi,

about the parade issue: may that have been due to "hot-swapping" the 
makumba jar? there is a known bug about tomcat (not parade) getting 
messed up when a new makumba version is placed in a context, even when 
the web-app is uninstalled before that change.

[Makumba-user] the wbr tag

[Cristian B. <cr...@cs...>]

Hi

did it ever happen to you that a very-long-word (like a long URL) in a 
table messes up the whole table because browsers (Firefox, IE, Safari) 
prioritize the longest word in the column over stuff like width=NNpx or 
width=NN% ?

the non-standard HTML <wbr/> tag does the trick, it indicates to the 
browser that it can break the word/text at a certain point in the word, 
if it needs to

http://www.jroller.com/gmazza/entry/forcing_html_line_breaks_within

for example in a long URL you can insert a WBR after each /...

Re: [Makumba-user] [Makumba-devel] Fwd: DANTE - Help me! questions about makumba

[Gwenael A. <gwe...@be...>]

Thanks a lot guys for the input.
FYI here is below what I answered Dante to his questions:
   * What is the meaning of the word MAKUMBA?
   * Why the framework have this name?

Stefan, just let me know if I should have added your name and I will
do so (Cristi, you have already been mentioned as Dr Cristian Bogdan,
researcher at Stockholm university KTH :)).

Hugs,
Gwen

[...]
Initially (around 1999) the framework was named "metadata" but was
quickly re-branded "macumba" in reference to a story, somehow
involving macumba [1], told during parties of the student organization
BEST (who's IT group is at the origin of this framework): when we
realized "metadata" was a far too generic name to be recognized the
decision was made to rename it (April 2000). "macumba" was the first
(non-techie) thing that came up.
The name evolved further into "makumba" due to the fact that all
variants of macumba domain were taken, so slight
adjustment of the name was needed, becoming "makumba" in October 2000
[personally I also think that "k" looks nicer than "c" :)].
Retrospectively it is a quite lucky name as the makumba framework
comes with quite some powerful features, almost able to do some
"magic"... Another parallel was drawn by a PhD student when attempting
to justify the name of his thesis, quoting: "[as the project grew]
some similarities between Makumba technology and Macumba religion
could be seen; they both have small tribes of firm believers".

i know the term since one of Timisoara's early summer courses, 1993, 
1994 or 1995. there were some people who had a makumba party, organized 
by one of the SC participants. of course they wouldn't tell anybody what 
it is about more than "you go in a room, you turn off the lights and

Re: [Makumba-user] [Makumba-devel] Fwd: DANTE - Help me! questions about makumba

[Stefan B. <ste...@gm...>]

A bit more of the juicy details....
Term "Makumba" became widely popular in BEST during the first JAMboree
in October 1998 [1] in some hills near Kemence in Hungary [2].

There was a joke about a French fighter pilot crashing his plane in the
jungle. The natives found him and gave him the choice "Macumba or
death". He bravely chose death, so they gave him "Macumba till death".

The joke had to be told slowly, in small groups a dark corner of the
castle, with plenty of Norwegian VikingsFjord [3] involved. Needless to
say, it was viral marketing at its best, recruiting new people at an
alarming rate. Some T-shirts were sacrificed [attachment]. If there
would be a tattoo artist present, some of us would probably still be
wearing Makumba tattoos :) In the aftermath of the event a short lived
macumba mailing list was established (hosted in zagreb) and a Macumba
Interested Group (MIG) was established.

The term stayed, silently anchored in our heads, representing suspense,
mystery and bravery. When we realized "metadata" was far too generic
name to be recognized the decision was made to rename it (at GA2000 in
April in Stockholm). "Macumba" was the first (non-techie) thing that
popped to our mind. All variants of Macumba domain were taken, so slight
adjustment of the name was needed, becoming Makumba in October 2000.

When project grew with time, some similarities between Makumba
technology and Macumba religion could be seen; they both have small
tribes of firm believers. (At least I wrote so when i needed to
officially justify the name in my thesis :D )

not much more, in 1999 when we started we had another name (metadata, 
known in athens summercourse 1999 as metafeta) but by the GA 2000 (i 
think) we thought that name is not best-specific-enough. i think it was 
a discussion between Igor Borojevic, Stefan Baebler and myself, not sure 
who else took part. Though I might confuse that discussion with the 
discussion where Igor (I think) baptised Karamba.

or it may be that they were "branded" at about the same time, which in 
retrospect looks like a smart move. at the time we had Minerva which was 
more or less done in makumba (but only the DB layer survived from that 
makumba version, the rest was some non-jsp templating, i think JHTML was 
involved, see below), PA which was in Lotus Notes and Johnny which was a 
java application with a "avant la lettre" JSP-like language that I and 
Ovidiu developed since 1996 (it was called JML, Sun's JHTML appeared 
after, based on a product called ATG Dynamo, and JSP appeared around 
2000 as a marketing response to ASP) and persisted its state as Java 
serialization. I imported data from all those in Makumba in a painful 
2001 summer (i had planned 2 days for it, it took 2 months).

so can you imagine that BEST committed to a makumba that was more or 
less just an idea, had no mak:list and not to mention mak:form in 2000? 
karamba design discussions (workshop and GM workgroups) were well under 
way already in 2000. Stefan stayed in Stockholm 6 months autumn/spring 
2000/2001 working on implementing both the makumba and the karamba 
concepts, as well as joining these karamba working groups. we also made 
the bundle then. i think after Stefan left came the idea of implementing 
makumba as a JSP taglib, so when i did the data import in the summer 
2001 i already had mak:list to look at it. i designed and implemented 
mak:form and BL in autumn 2001 in Ivrea at a summerschool. finally we 
had a complete makumba. i don't know when we switched to tomcat, i guess 
ever since we worked with jsp. before that, there was something called 
Java Web Server and it was the reference implementation for JHTML.

then ITC started the implementation of PA TS, Minerva TS and Johnny TS 
(= transitional system, i.e. a makumba clone of the original). parade 
was developed quite fast in early 2002 and launched during a ITC meeting 
(Risto called it paralyzed development). i think Johnny TS (which was 
crucial for the success of the whole mak+karamba enterprise) was put in 
production in summer 2002, Raul started it and went home, then it turned 
out that there had been an outofmemory exception when running the import 
that i had developed already a year before, so lots of people and their 
applications were missing. we did a re-import and a handful of 
applications (entered before we realized that the import was wrong) were 
lost, but overall it was ok. just in time because johnny had not been 
designed to be multi-season and it was caching all its data, so we talk 
1 Gb RAM (there were no Java weak references at the time) and 1-2 hours 
to start up. i don't remember when PA-TS and Minerva TS were launched. 
then there was one project left, the account merging, that took much 
longer to complete.

if you want to find out the precise "makumba" moment and circumstances, 
maybe ask the above people, and Toto. see also the list of initial 
makumba meetings
http://www.makumba.org/makumba.html
... so the makumba.org domain name was bought in summer/autumn 2000 but 
the package name remained metadata until late 2000. if i look at that 
document now it seems that we were in the confused design space 
exploration that lasted quite long (over 2 years!) before the mak:list

i think that also a ptrOne is a referential action, so ideally we would 
have it defined in the MDD to delete also that object.
mak can then easily find out that it should first delete the referred 
object.

yes they are, one is the person which has a pointer to the authentication

but it's a ptr, not a subrecord (ptrOne).

this is exactly the case we fight with in BL (the foreign key issue)

i guess both should work, since they both work in forms/object 
creation/editing.

or we should cut short these form efforts as they actually do BL :) and 
design better BL (near MDD) :)

are o1 and o2 in any way related to each other in this case? if so, that 
should be in many cases a referential action, right?

otherwise, no, never tried.. i think if that is needed, the second 
proposal with nested deletes seems more logical to me.

i think it requires a body.

[Makumba-user] more <mak:delete>s in a multiple form?

[Cristian B. <cr...@cs...>]

did anybody ever try anything like this?

<mak:form action="...">
<mak:delete object="o1" />
<mak:delete object="o2" />
</mak:form>

or even
<mak:delete action="..." object="o1">
<mak:delete object="o2" />
some text here
</mak:delete>

even if this should really be a business logic stuff, it would be 
expected to work since creating more objects at a time also works...

in general, anybody knows how does mak:delete behave in a multiple form? 
is it ok to do <mak:delete/>, i.e. with no link text?

also, deletion order is interesting (related to foreign keys)

I guess it is simply using "0<1" and everything that gets 0 is displayed 
before 1

Re: [Makumba-user] subquery of the day

[Cristian B. <cr...@na...>]

well basically boolean gets translated to 0 and 1 at SQL level.

like if you SELECT 1=0 you get a 0...

mysql> select 1=0;
+-----+
| 1=0 |
+-----+
|   0 |
+-----+
1 row in set (0.00 sec)

Re: [Makumba-user] tomcat 6

[Cristian B. <cr...@na...>]

Hi

I needed to test another tomcat for profiling reasons so I placed a 
makumba-based WAR in the webapps of a tomcat 6 download. The only thing 
i needed to do was to copy a commons-logging.jar (used by hibernate i 
think) in the lib of the tomcat. could have been in the WAR itself i 
guess, but it wasn't since tomcat 5.5 was distributed with it.

If you want JDBCRealm authentication you'll also need to copy mysql.jar 
in the lib.

for the rest everything seems to work as expected
