Error opening project file with database reference

[kijato]

I need to use data stored in Postgis. I can add the data source to the project, I can see the data in openjump and I can save the project to file. But, I cannot open the project file with the following error:

java.lang.Exception: 'C:\tryIt.jmp Projekt fájl betöltése megszakadt class com.vividsolutions.jump.util.java2xml.XML2Java cannot access a member of class com.vividsolutions.jump.datastore.spatialdatabases.SpatialDSLayer with modifiers "private" error.

How can I solve it...?

Hi Kijato, I will try to reproduce. Can you please write the version of OpenJUMP you're using

[mukoki]

Hi Kijato,

Indeed, the bug has been fix recently https://github.com/openjump-gis/openjump/commit/0906acbc6b7710896bdbe9882fc98ba1c93c2b4b

You will have to grab a snapshot (https://sourceforge.net/projects/jump-pilot/files/OpenJUMP2_snapshots/), or to wait for the next official release. The good news is there should be one soon :-)

Hi Mukoki,

That is a great news, then I must to use the snapsot at now. May I ask where could I to find more (up-to-date) information if I would like to try the running from source, or I would like to develop some plugin for my works? _(When I try to import the openjump from Github to Eclipse then I can catch the "OJdocs" only. I am sure I am wrong anything but when/where...?)

Thx, kijato

Hi Kijato,

Documentation is a bit old, but you'll find useful resources here : http://www.openjump.org/

For example, downloading instruction : https://ojwiki.soldin.de/index.php?title=Downloading_OpenJUMP#Source_Code

running it in eclipse : https://ojwiki.soldin.de/index.php?title=How_to_run_OpenJUMP_in_Eclipse

making your own plugin https://ojwiki.soldin.de/index.php?title=How_to_use_and_make_own_Plugins

Some pages still refer to OpenJUMP 1.x version and may contain outdated example

Hi,

There is a new syllabus: Eclipse: Set up OpenJUMP as a Maven project from git sources.

Thx for edeso! ☺️
