[Geoserver-users] copy styles directory

Jim_White · September 6, 2013, 12:10am

Hi,

I created a new workspace and copied the styles directory from another server, but I don’t see the copied styles listed when I click the styles link. What do I need to add to get them to appear?

Thanks,
Jim

Hello Jim,

have you also copied the stylename.xml? This file has an ID which is
essential to reference and register the style with geoserver.

This ID turns up with the layer.xml in the workspace:

<layer>
  <name>VMADD.ADDRESS</name>
  <id>LayerInfoImpl--4c68f0d5:128cd132f0d:-7f8a</id>
  <type>VECTOR</type>
  <defaultStyle>
    <id>StyleInfoImpl--*2e0631ee:136997f03ca:7037*</id>
  </defaultStyle> etc, etc.......

That is why it makes sense to copy both directories, 'styles' and
'workspace' otherwise you will have layers that reference a style that does
not exist and styles that are not used by your layers and the name does not
matter as the connection is via the ID above.

Cheers

Christian

Hi Jim,

cave you copied the stylename.xml files with the sld files?

They look like this:

This ID is the definition and the reference for geoserver. It turns up in
the layer.xml

<layer>
  <name>VMADD.ADDRESS</name>
  <id>LayerInfoImpl--4c68f0d5:128cd132f0d:-7f8a</id>
  <type>VECTOR</type>
  <defaultStyle>
    <id>StyleInfoImpl--*2e0631ee:136997f03ca:7037*</id>
  </defaultStyle>.....

which is why it makes sense to copy always both, the 'styles' directory and
the 'workspaces' including their subdirectories. Otherwise you will have
layers without valid styles and styles without layers.
The names of styles do not matter for geoserver internally.

Actually there is more to it, which is the integrity between workspaces and
stores and layers and layergroups and styles. And, if you reference for
instance shapefiles and not just databases the data directory as well.

Because of that I thought it always safer to copy the entire data directory
and then update 'www', 'plugins', 'security', 'user_projections' and all the
other stuff when updating geoserver.
