i didn't try but read that it was removed in _java 11_ already. the startup 
scripts are now modified accordingly.

only natural as PLUS is our default download since some time.

that's probably true, still i'd advise to apply some discipline, if at all 
possible, because we know of the sizes of the other JUMP clones (even minus 
shipped jre's) and we probably really do not want to end up there.

still, in the end we are a project of volunteers and i will accept the vote of 
a majority of contributors :).. let's see what Jukka has to say. still waiting 
for him to chime in.

Re: [JPP-Devel] NoClassDefFoundError when starting OJ r5929 with JDK 12

[Michaël Michaud]

Hi Ede,

If we do not include jaxb in the future, we'll also have to remove 
SetAttribute extension


https://sourceforge.net/projects/jump-pilot/files/OpenJUMP_plugins/More%20Plugins/SetAttributes%20PlugIn/

I think that removing these extensions is not an urgent matter if it 
only hurts java12 which is not yet official.

Let's keep it at least until the next OJ release.

Note that currently (1.13), we have 277 downloads for PLUS version and 
only 16 for CORE.


My understanding is that most users want features and don't mind too 
much about size. Despite this,
I think that keeping the CORE as light as possible makes sense, but 
applying the same diet to PLUS distro
is just a way to condemn excluded extensions to oblivion as we have no 
extension manager.

Yes Michael,
my comparition was to explain to Ede what LayerManagerExtension and
LayerView plugin can do.
IMO I think that LayerManagerExtension is a good plugin to have in in
OpenJUMP one day.
Regarding depency, Sextante has a depency to a lib "kxml2.jar" which
possibly can help inthe future

well no, it is shipped with CORE but actually is an extension in lib/ext/ and 
installs itself. but ok, then take cadplan printer, which is shipped w/ PLUS


com.cadplan.jump.PrinterPlugIn

>do not exist in the CORE ? 

yes. the plugin class simply needs to be within the scope of our classloader. 
then 

 
my.super.plugin


...



installs it.

'initialize=false' though, does not prevent installing. it merely does not run 
the install routine in plugin manager and the extension does have to do it 
themselves. but when they do, they use featureinstaller, which in turn checks 
for the values in default-plugins.xml, nifty no? 

>
Should we maintain two default-plugins.xml ? 

why? the idea is to have _one_ place, where we can sort menu entries or modify 
them to our will. i would not know how to maintain sequence when two files are 
used.

>And what abou third-party extensions that we want to include in PLUS ?

works already, doesn't it? some PLUS extensions are probably already sorted via 
default-plugins.xml and if not they are simply added to the end of their 
corresponding menu.

 how about we remove it and if users complain we at least know it is in 
 actual use and think of a solution?

well, maven registries usually maintain dependency lists. the entry above does 
state only a compile time dependency to one other jar. no runtime dependencies 
at all. not saying it's correct, just stating what it says.

What should be placed by default-plugins.xml ? I think it is the role of the

we can actually modify any aspect of the plugin installation here (icon, name 
etc.)
I know using default-plugins.xml gives a good control over plugin 
installation without changing the code, but in your example, this is a 
plugin that is included in OJ Core. What about real extension which we 
dont want in the core like the ViewManagerExtension ? Can we use 
default-plugins.xml to install plugins that do not exist in the CORE ? 
Should we maintain two default-plugins.xml ? And what abou third-party 
extensions that we want to include in PLUS ?

Michaël

how about we remove it and if users complain we at least know it is in actual 
use and think of a solution?

so Mike, rather removal or adaption? btw. the maven jar is merely 90kB big, 
wouldn't javax.xml.bind suffice?
   https://mvnrepository.com/artifact/javax.xml.bind/jaxb-api/2.1
I think that we'll need several additional jars : jaxb-api, jaxb-core, 
jaxb-impl, activation
That means 1.4M. But I did not test anything. It would be a good new if 
jaxb-api was sufficient ;-)


I'd rather remove the extension than review its persistence mechanism 
because anyway, I generally package a specific distro to users I know. 
But before, I wish to hear from Jukka and Peppe, because if they 
sometimes use this extension, or know people using it, it maybe 
worthwhile letting it in PLUS distro, event at the price of +1.4Mb.

well yes ;).. when i redesigned the plugin loading i made it possible for us to 
finetune plugin installing as we want it, because we might know better where to 
place it or simply want to force some order onto things.
another reason was to make it possible to influence plugin installing w/o 
needing to patch the extension first. you might want to check eg. how 
skyprinter is placed to a different location


com.isa.jump.plugin.PrintPlugIn





we can actually modify any aspect of the plugin installation here (icon, name 
etc.)

HI Ede


right. what does it do by the way. i saw it lacks german translation 
which i could do if i know what it does. it seems to be hidden in the 
Plugin menu as well and should be placed properly via def-plugins.xml 
if we decide to keep it. 
What should be placed by default-plugins.xml ? I think it is the role of 
the extension to place its own plugin isn't it ? default-plugins is not 
supposed to know anything about extension's plugin or did I miss something ?

Re: [JPP-Devel] NoClassDefFoundError when starting OJ r5929 with JDK 12

[Michaël Michaud]

Hi,

The exception noticed by Jukka was not from LayerView but from 
LayerManagerExtension


Both are about styling layers, but with different goals :
- LayerView is a Layer which uses the data of another layer as its 
datasource. It makes it possible to apply a second style to a dataset 
without duplicating the data. There was a bug reported by Peppe a few 
days ago about this plugin : a project containing LayerViews could not 
be save / restore. The bug is partly resolved.


-LayerManager is an extension to save styles associated  to different 
layers without saving the data, in order to re-use the the styles with 
another dataset having the same structure but different data. It uses 
jaxb as its persistence mechanism, and this is the one that is 
incompatible with JDK 12ea recently tested by Jukka (because jaxb has 
been removed from the jdk).


Ede, there is a small introduction on this extension here :
https://sourceforge.net/projects/jump-pilot/files/OpenJUMP_plugins/More%20Plugins/ViewManager%20PlugIn/

Hi Ede
Layer views are basically different views of the layer with 
(optionally) different styles applied
In order to simplify you can consider layer views as sinonimous of 
styles of layer (Layer>Style>Change styles)

See also the new plugin in the layer toc "Add layer view"

right. what does it do by the way. i saw it lacks german
translation which i could do if i know what it does. it seems to
be hidden in the Plugin menu as well and should be placed properly
via def-plugins.xml if we decide to keep it.

Re: [JPP-Devel] NoClassDefFoundError when starting OJ r5929 with JDK 12

[Michaël Michaud]

Hi Ede,

You can have a look at ViewManager in the PlugIn repository. May not be 
so difficult to change but many classes have to be serialiable and 
configured through java2xml files. At the time I choosed jaxb, I may 
have tried java2xml and encountered some difficulties to modelize 
heritage through java2xml, but I'm not sure.


When I wrote it, i was quite familiar with jaxb and it seemed to me that 
it was a more modern (annotation-based), more standardized (available in 
jre) and more flexible way to serialize classes to xml than java2xml, 
but I like light-weight plugins and I admit that 1.4Mo is a bit 
expensive for such a plugin. Also it it is difficult to make it lighter, 
we can also remove it from the PLUS distro.

Error does not happen with Java 8.  OpenJUMP does work despite the error

yeah. that needs to be fixed in ViewManager, probably by Mike as he created the 
extension. it uses code (javax.xml.bind) which is not part of the jdk anymore 
since java 11. replacing it with one of the other xml implementations we use 
should be not to hard.

Mike? do you need a ticket?.. ede
