Hi Akin Here are the answers to your questions: 1) If I use only shapefiles, I don't need a database? - Correct. Shapefiles replace the use of a database. However, I still recommend using a database, but when you feel comfortable. 2) How can I use my own shapefile, where should I start and I dont know how modify the program, Should I change whole program segments javascripts, xml, jsp,... files - Go to this page here for a tutorial on how to add a shapefile to GeoServer: http://docs.codehaus.org/display/GEOSDOC/User+Tutorial+Shapefile You don't need to edit javascript or anything. 3) I need some constant shapefiles, I don't know how to create because I install the jump but it did not open my .shp file and it use own file format new task and .jmp, also I need a shapefile which will change according to new data - Ah, jump can take some getting used to. To load a shapefile into Jump, go to File->Load Dataset. On the top left of the file browsing window that pops up, make sure the 'Format' drop down list has ESRI Shapefile selected. Locate your .shp file and hit 'OK'. To save out your shapefile, go to File->Save Dataset. On the top left of the file browsing window that pops up, make sure the 'Format' drop down list has ESRI Shapefile selected. Name your file and make sure it has a .shp extension. Hit 'OK'. - Shapefiles can be edited by yourself using Jump (and other tools) and by GeoServer. So they will constantly change. 4) Can I create shapefile with java - You sure can, and there are several ways to do this. You can use GeoTools and create a new ShapefileDataStore or you can use the JTS library (http://www.vividsolutions.com/jts/jtshome.htm) to create a shapefile. The JTS jar should come with Jump. - I suggest you look around in org.vfny.geoserver.wfs.responses.ShapeFeatureResponseDelegate.java to see how shapefiles were used there.
