Well if it stopping when it checks the params then it will not even try to
connect sigh ... here is the code?
Q: Can you see anything that would prevent your params being accepted?
Q: is the postgis-versioned jar in libs? Try removing it to see if that helps
with the checkDBType
Q: Do you have the geotools source code to walk through this in a debugger? It
would be good to know *which* param it is not accepting?
1) JDBCDataStoreFactory
public boolean canProcess(Map params) {
if (!super.canProcess(params)) {
return false; // was not in agreement with getParametersInfo
}
return checkDBType(params);
}
2) super.canProcess(params)
public boolean canProcess( Map params ) {
if (params == null) {
return false;
}
Param arrayParameters[] = getParametersInfo();
for (int i = 0; i < arrayParameters.length; i++) {
Param param = arrayParameters[i];
Object value;
if( !params.containsKey( param.key ) ){
if( param.required ){
return false; // missing required key!
} else {
continue;
}
}
try {
value = param.lookUp( params );
} catch (IOException e) {
// could not upconvert/parse to expected type!
// even if this parameter is not required
// we are going to refuse to process
// these params
return false;
}
if( value == null ){
if (param.required) {
return (false);
}
} else {
if ( !param.type.isInstance( value )){
return false; // value was not of the required type
}
}
}
return true;
}
3) PostgisNGDataStoreFactory.checkDBType
protected boolean checkDBType(Map params) {
if (super.checkDBType(params)) {
//check for old factory
try {
Class.forName("org.geotools.data.postgis.PostgisDataStoreFactory");
//old factory is around, let it handle the connection
return false;
}
catch(ClassNotFoundException e) {
//old factory is not around, handle this connection
return true;
}
}
else {
//check for postgisng as well
return checkDBType(params, "postgisng");
}
}
