Hi all.
I'm working with LargeObjectManager to create LOB object as the
documentation examples.
I have postgresql 7.0.2 with jdk1.2 and jsdk20
I have the following method to create LOB objects:
***********************************************************************
private int createLOB(ByteArrayInputStream bais) throws FileNotFoundException, IOException, SQLException {
System.err.println("Creating a large object");
int oid = lobj.create(LargeObjectManager.READ|LargeObjectManager.WRITE);
System.err.println("Open a large object");
LargeObject obj = lobj.open(oid,LargeObjectManager.WRITE);
System.err.println("Copying file to large object");
byte buf[] = new byte[2048];
int s,tl=0;
while((s=bais.read(buf,0,2048))>0) {
System.out.println("Block size="+s+" offset="+tl);
obj.write(buf,0,s);
tl+=s;
}
System.err.println("Closing object");
obj.close();
return oid;
}
**************************************************************************
when I insert the LOB object in a table:
ByteArrayInputStream bais = new ByteArrayInputStream(x);
int oid = createLOB(bais);
String query = "insert into tupdate values ('"+ pkey_value +"','" + CN + "','" + client + "','" +requestFormat + "','" + date + "','" + oid + "','" + updated +"')";
s.executeUpdate(query);
connection.commit();
bais.close();
It work fine, but sometime (only sometime) fail with:
FastPath call returned FATAL 1: my bits moved right off the end of the world!
