Hi,
i'm trying to append a large number (about 2000 or more) of small pdf
documents (1 or 2 pages) in single document, by my program runs out of
memory in a short time.
This is my code:
public int appendDocs(Connection conn, String arg1, int arg2, int arg3)
throws Exception{
DataSet ds = GestCedo.getSqlLayer().getCedolini(conn, arg1, arg2,
arg3);
ResultSet rs = ds.getRs();
Document destination = new Document(PageSize.A4);
PdfCopy writer = new PdfCopy(destination, new
FileOutputStream(fileName));
destination.open();
int n = 0;
int totPages = 0;
try {
while (rs.next()) {
n++;
BLOB pdf = ((OracleResultSet)rs).getBLOB(1);
InputStream is = pdf.getBinaryStream();
PdfReader reader = new PdfReader(is);
reader.consolidateNamedDestinations();
totPages = reader.getNumberOfPages();
for (int i = 1; i<=totPages; i++){
PdfImportedPage page = writer.getImportedPage(reader,
i);
writer.addPage(page);
}
writer.freeReader(reader);
is.close();
is = null;
reader = null;
pdf = null;
if (n%100==0) {
Runtime.getRuntime().gc(); //unuseful try
}
}
} catch (Exception e){
System.out.println(e.getMessage());
}
destination.close();
rs.close();
ds.getSt().close();
return n;
}
Anyone can suggest me a solution?
