Hi Jukka, thanks for the quick answer. Regarding user/password of WMS, I can see that the code comes from SelectUrlWithAuthPanel.class but I don't see where these datas are stored on WMS classes ( or maybe not, they are only asked at the beginning of the WMS request process).
This plugin is relatively simple. If you have time you can see the code on class org.openjump.core.ui.plugin.wms.WMSLegendPlugIn. The core of legend request is Line 71, the String getLegendUrl(PlugInContext context, String names). The String is divided into 3 parts: a) PlugInContext refers to WMS layer where to extract the URL calling layer.getService().getServerUrl(). b) while String "names" is the name of the WMS layer. c) the rest of the code calls GetLegendGraphic, Version, etc, including some graphical components for the legend. I don't have experience with WMS. I understood from your code ( https://username:pas...@site.fi/cgi-bin/service1?) that that user/password should before the the server URL string (part a of String getLegendUrl) . If so, and if OJ memorize somewhere those datas, it should be easy to modify this String to get Legends from WMS withcredentials. Otherwhise I should build "ad hoc" another panel where users have to enter those info again. Regarding ChangeWMSStyleDialogPlugIn, I gave a look to it thinking to port to OpenJUMP. While GetLegend is relatively easy as it is shown a new image on a separate panel, for the Style it should redraw the workbench. Which I still don't know how to do. I really appreciate any comment or help on the code from you.
