gwt - Symbol not found - Java -

i'm using olap4j connect olap server in gwt. however, when try iterate through rows , columns 'symbol not found' error during compilation.

my code

for (position axis_0 : cellset.getaxes().get(axis.columns.axisordinal()).getpositions()) {             list<member> mem0 = axis_0.getmembers();             (position axis_1 : cellset.getaxes().get(axis.rows.axisordinal()).getpositions()) {                 list<member> mem1 = axis_1.getmembers();                 cell currentcell = cellset.getcell(axis_0, axis_1);                 data = new hashmap();                 (int = 0; < mem0.size(); i++) {                     data.put(mem0.get(i).getdimension().getname().replaceall(" ", ""), mem0.get(i).getuniquename());                 }                 (int = 0; < mem1.size(); i++) {                     data.put(mem1.get(i).getdimension().getname().replaceall(" ", ""), mem1.get(i).getuniquename());                 }                 data.put("value", float.parsefloat((currentcell.getvalue()==null)?"0":currentcell.getvalue().tostring()));                 data.put("cellid", count);                 data.put("scenarios", scenario);                 collection.add(data);                 count+=1;             }         } 

the error

i able code validated restructuring this:

    cellsetaxis columnaxis = (cellsetaxis) cellset.getaxes().get(axis.columns.axisordinal());     cellsetaxis rowaxis = (cellsetaxis) cellset.getaxes().get(axis.rows.axisordinal());     list<position> colpositions = columnaxis.getpositions();     list<position> rowpositions = rowaxis.getpositions();      (position axis_0 : colpositions) {         list<member> mem0 = axis_0.getmembers();         (position axis_1 : rowpositions) {             list<member> mem1 = axis_1.getmembers();             cell currentcell = cellset.getcell(axis_0, axis_1);             data = new hashmap();             (int = 0; < mem0.size(); i++) {                 data.put(mem0.get(i).getdimension().getname().replaceall(" ", ""), mem0.get(i).getuniquename());             }             (int = 0; < mem1.size(); i++) {                 data.put(mem1.get(i).getdimension().getname().replaceall(" ", ""), mem1.get(i).getuniquename());             }             data.put("value", float.parsefloat((currentcell.getvalue()==null)?"0":currentcell.getvalue().tostring()));             data.put("cellid", count);             data.put("scenarios", scenario);             collection.add(data);             count+=1;         }     }
