jxls - multiple row (list) binding doesn't work

Question

I'm trying to create excel form using jxls library.

my excel template is :

when I just add one map to list and bind it, it works. my code is simply :

List<Map<String,Object>> sss = new ArrayList();

HashMap<String,Object> sm = new HashMap<String,Object>();
sm.put("name1", "AtestName");
sm.put("name2", "AtestName2");
sm.put("name3", "AtestName3");
sss.add(sm);

Map<String, Object> model = new HashMap<String,Object>();
model.put("sData", sss);
....  XLSTransformer transformer = new XLSTransformer(); .....

but when I add multiple map to list and bind it, it fails throwing exception. I heard jxls library automatically recognize list. What am I doing worng?

List<Map<String,Object>> sss = new ArrayList();
HashMap<String,Object> sm = new HashMap<String,Object>();
sm.put("name1", "AtestName");
sm.put("name2", "AtestName2");
sm.put("name3", "AtestName3");
sss.add(sm);

HashMap<String,Object> sm2 = new HashMap<String,Object>();
sm.put("name1", "BtestName");
sm.put("name2", "BtestName2");
sm.put("name3", "BtestName3");
sss.add(sm2);

HashMap<String,Object> sm3 = new HashMap<String,Object>();
sm.put("name1", "CtestName");
sm.put("name2", "CtestName2");
sm.put("name3", "CtestName3");
sss.add(sm3);

Map<String, Object> model = new HashMap<String,Object>();
model.put("sData", sss);
....  XLSTransformer transformer = new XLSTransformer(); .....

Answer 1

The error you get java.lang.NoSuchMethodError:org.apache.poi.ss.usermodel.Sheet.getSheetConditionalFormatting most likely means that you have an issue with POI versions.

So please check the Apache POI version you do use and if it supports Sheet.getSheetConditionalFormatting() method
