problem using mapscript with java to getfeature WFS

[victorH]

Use mapscript library to make a consult "WFS getfeature" to "MAPSERVER" to MS4W.

I prove the java example in this url,

"​http://mapserver.gis.umn.edu/docs/howto/wxs_mapscript/#java-example"

Adapted for WFS GetFeature. This it is the code that causes the error

" import edu.umn.gis.mapscript.mapObj; import edu.umn.gis.mapscript.OWSRequest; import edu.umn.gis.mapscript.mapscript;

class WxSTest_thread extends Thread {

public String mapName="C:
ms4w
Apache
htdocs
mapserver
hidrocarburos
hidrocarburos.map"; public byte[] resultBytes;

public void run() {

mapObj map = new mapObj(mapName);

map.setMetaData( "ows_onlineresource", "​http://dummy.org/" );

OWSRequest req = new OWSRequest();

req.setParameter( "SERVICE", "WFS" ); req.setParameter( "VERSION", "1.0.0" ); req.setParameter( "REQUEST", "getfeature" ); req.setParameter( "TYPENAME", "estaciones_servicio");

mapscript.msIO_installStdoutToBuffer();

int owsResult = map.OWSDispatch( req );

if( owsResult != 0 )

System.out.println( "OWSDispatch Result (expect 0): " + owsResult );

resultBytes = mapscript.msIO_getStdoutBufferBytes();

}

}

public class Wxs {

public static void main(String[] args) {

try {

WxSTest_thread tt[] = new WxSTest_thread[100]; int i; int expectedLength=0, success = 0, failure=0;

for( i = 0; i < tt.length; i++ ) {

tt[i] = new WxSTest_thread(); tt[i].mapName = args[0];

}

for( i = 0; i < tt.length; i++ )

tt[i].start();

for( i = 0; i < tt.length; i++ ) {

tt[i].join(); if( i == 0 ) {

expectedLength = tt[i].resultBytes.length; System.out.println( "Document Length: " + expectedLength + ", expecting somewhere around 10000 or more." );

} else if( expectedLength != tt[i].resultBytes.length ) {

System.out.println( "Document Length:" + tt[i].resultBytes.length + " Expected:" + expectedLength ); failure++;

} else

success++;

}

System.out.println( "Successes: " + success ); System.out.println( "Failures: " + failure );

} catch( Exception e ) {

e.printStackTrace();

}

}

} "

And obtain this error

the class that produce the error

[unicoletti]

Can you send me the map file, I believe it's something there. On my computer it runs well with test.map from mapserver source.

Please send it to: umberto.nicoletti _at_ gmail.com

[unicoletti]

Victor, you never sent the mapfile...I assume in the end it worked out. Closing.
