java - Convert ZipOutputStream to FileInputStream -

i have code takes file, zip it, , stores in database

looks

          // step 1 - create zip file           byte[] buffer = new byte[1024];// 18024           zipoutputstream outzip = new zipoutputstream(new fileoutputstream("file.zip"));           outzip.setlevel(deflater.default_compression);           fileinputstream in = new fileinputstream(c:\file.hex);           outzip.putnextentry(new zipentry("file.hex"));           int len;           while (( len = in.read(buffer)) > 0)                 outzip.write(buffer, 0, len);           outzip.closeentry();           in.close();           outzip.close();            // step 2 - insert zip file db           file = new file("file.zip");           fileinputstream fis = new fileinputstream( file ); 

the fis object store in db

but avoid filesystem , , not create file.zip. think need convert zipoutputstream fileinputstream directly not find way it.

is there easy way accomplish ?

• i have same problem when extract file, in order read must create 2 different temporary files - file.zip , file.hex

you not have create fileoutputstream @ all. use bytearrayoutputstream instead:

bytearrayoutputstream zipbytes = new bytearrayoutputstream() zipoutputstream outzip = new zipoutputstream(zipbytes);  // run code adds zip entries....  zipbytes.getbytes() // returns array of bytes contain zipped information.
