Обсуждение: truncated InputStream returned with getAsciiInputStream()
Hi I've seen a couple of discussion about this subject, and I wonder if you could help me finding a workaround for my problem too. I work with big XML documents, around 12000 to 15000 characters. Since these documents were occasionnally causing me performance problems during store operations, I tried using java.util.zip package's "deflate" and "inflate" methods to compress my data. These method output byte arrays, and the bytes can have any arbitrary value. Including "-1". So now, to store my data in the database, I use BLOB instead of TEXT. It works fine, my data is stored and retreived without any problem with method set and getAsciiStream()... until there is a byte with value "-1" in my Stream. If the 43rd byte is "-1", the stream has a length of 42. The problem is that I cannot really escape the character, since it's compressed data, and I can't just remove it assuming it's a null character, cause it's not. Somebody has a clue? Isabelle

If the 43rd byte is "-1", the stream has a length of 42. Can you post a small program that reproduces the problem? Regards, René Pijlman <rene@lab.applinet.nl>
Is there a reason you are not using getBinaryStream()? You can't read a binary file with and AsciiStream. thanks, --Barry Isabelle Therrien wrote: > Hi > > I've seen a couple of discussion about this subject, and I wonder if you > could help me finding a workaround for my problem too. > > I work with big XML documents, around 12000 to 15000 characters.
