Hello, Rainer Klute. I use POI well for access to Excel. It's great for user.
But there is one problem. I want to write 40000 line(row)s by Excel Format using POI. It may be 300,000 cells. Then, when executes, JVM has many memories and finally memory out. It's first time for me to be out of memory for JVM. So, I divides it into 5000line since there is no time. But I want to know how soloves this. Maybe.. Dividing smaller parkets and writing it into same file step by step is same job to write whole data. regards for answer. by Park from south korea ,opened 2002 KOREA-JAPAN World Cup. PS. Sorry for weak English sentense. I worry that you missunderstadings by this.
