Uploading External Documents (*.doc, *.pdf, *.html) using JSP, Servlets, JDBC

Question

I would like to upload external documents to an Oracle 8.16 db without using agents or interMedia.
Documents can range from *.doc, *.pdf, *.html and so forth. Ive been all over OTN and all I keep finding are examples on uploading Audio, Video or Image data - which is fine.. but damn, can we get a couple "Real World" examples in there?
Im even looking at iWorkplace which is excellent.. but a little out of my league when it comes to uploading external documents. But that's exactly what Id like to do. The documentation on this issue is very scarce - Please help.
Any help in this matter would be greatly appreciated.
Many Thanks in Advance.

Answer 1

Is anyone having problems loading text files using this routine? I can load a file with this, but even though the table contains a CLOB, the file is uploaded as binary and one only sees a series of question marks when looking at the CLOB. So, basically, the file appears to be converted somehow from text to binary. Any thoughts? I'm using 8.1.6.0.0 on Sun Solaris 2.7. character set in the database is UTF8.
Thanks.

Steps you need to follow are:
1. Create a table to hold the documents
CREATE TABLE XML_DOCUMENTS (
DOCNAME VARCHAR2(200) NOT NULL,
XMLDOC CLOB,
TIMESTAMP DATE
2. Create a directory
CREATE OR REPLACE DIRECTORY bfile_dir AS /private1/LOB/files;
3. Grant READ privileges on the directory to the appropriate user
GRANT READ on bfile_dir to SCOTT;
4. Create a procedure
CREATE PROCEDURE insertXmlFile( dir VARCHAR2,
file VARCHAR2,
name VARCHAR2 := NULL) IS
theBFile BFILE;
theCLob CLOB;
theDocName VARCHAR2(200) := NVL(name,file);
BEGIN
-- (1) Insert a new row into xml_documents with an empty CLOB, and
-- (2) Retrieve the empty CLOB into a variable with RETURNING..INTO
INSERT INTO xml_documents(docname,xmldoc) VALUES(theDocName,empty_clob())
RETURNING xmldoc INTO theCLob;
-- (3) Get a BFile handle to the external file
theBFile := BFileName(dir,file);
-- (4) Open the file
dbms_lob.fileOpen(theBFile);
-- (5) Copy the contents of the BFile into the empty CLOB
dbms_lob.loadFromFile(dest_lob => theCLob,
src_lob => theBFile,
amount => dbms_lob.getLength(theBFile));
-- (6) Close the file and commit
dbms_lob.fileClose(theBFile);
COMMIT;
END;
5. Execute the procedure
INSERTXMLFILE('bfile_dir', filename, 'description');
Good Luck!
