Saving features to SQL Server using Openlayers and geoserver -


i using sql server plugin geoserver (http://docs.geoserver.org/stable/en/user/data/database/sqlserver.html) show geometries using wms. works fine. able extract geometries vectors without trouble.

now need add retrieved vector layer , save table in sql server database. causing problems.

this of code:

savestrategy = new openlayers.strategy.save(); savestrategy.events.register("success", '', changessuccess); savestrategy.events.register("fail", '', changesfailed);  function changessuccess(e) {     alert('done'); }  function changesfailed(e) {     alert('failed'); }  selectionlayer = new openlayers.layer.vector(         "selectionlayer",         {             strategies: [new openlayers.strategy.bbox(), savestrategy]             , projection: new openlayers.projection("epsg:25832")             , protocol: new openlayers.protocol.wfs({                 version: "1.1.0",                 url: "http://someserver.cloudapp.net:8181/geoserver/wfs",                 featureprefix: 'xxxx',                 featuretype: "xxxxxxxxx",                 featurens: "xxx.xxx/xxx",                 geometryname: "xxxxx"             })             , displayinlayerswitcher: false         });  selectcontrol.events.register("featureselected", this, function (e) {     var feat = e.feature;     feat.state = openlayers.state.insert;     selectionlayer.addfeatures([feat]);     savestrategy.save(); );

when try save newly added feature following exception in fail event of save strategy:

"java.lang.abstractmethoderror:org.geotools.jdbc.basicsqldialect.encodegeometryvalue(lcom/vividsolutions/jts/geom/geometry;iljava/lang/stringbuffer;)v org.geotools.jdbc.basicsqldialect.encodegeometryvalue(lcom/vividsolutions/jts/geom/geometry;iljava/lang/stringbuffer;)v"

i don't know try here, if has encountered before or has suggestions on issue more happy hear it.. 1:50am here , not going bed before fixed suggestions more welcome :)

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
