OrdDoc.getMimeType() null
The following doc is loaded successfully and later added to the database successfully, but for some reason the mime type is always null. Any ideas?
OrdDoc doc = (OrdDoc) rset.getORAData(1, OrdDoc.getORADataFactory());
doc.loadDataFromFile(path + mf.getRef());
System.out.println(doc.getMimeType()); // null
Hi Mavris
Thanks for the reply.
In my example the reason i did not invoke setProperties() method is because the setProperties method exposed in OrdDoc class is not same as the setProperties method in OrdAudio or OrdImage.
In OrdDoc class setProperties(byte[][] ctx,boolean setComments) takes two arguments where as setProperties() in OrdAudio and OrdImage does not take any arguments.
byte[ ] ctx[ ] = new byte [4000][1];
When i tried to use setProperties(ctx,true) in OrdDoc i was getting an error.
Can you please tell if this is the correct way to invoke setProperties on OrdDoc in Java Program?
Regarding the list of format that Intermedia Understands, the Appendices A, B and C in Intermedia Refererence talks only about Audio, Image and Video. It doesnt have any details about Document (pdf, txt, doc) files. Can you please tell where can i look for the list of formats that intermedia understands for OrdDoc?
Since the dataType is OrdDoc in my table. How do i check the LOB length?
I tried it using Intermedia Java API by calling getContentLength method after retreiving the OrdDoc column from resultset but it has a value of '0'. So am not sure why the document is not getting loaded.
Please help me resolve this issue.
Thanks

Hello Gurus,
Getting DOC.getMimeType() as null when using ORADOC after Import , Unable to find the document type.
Importing is done through a URL using ordsys.orddoc.import(), the filename is an ID, we call the document using that ID, will not know the filetype until Opened.
Any Suggestions.
Thank youSorry Its ORDDOC not ORADOC

1. create a table in your database:
create table docs (id number(10), mov ordsys.orddoc);
2. write a simple BC4J app that just uploads a document to the "mov" column.
I suspect that ORDSYS.ORDDOC does not work well with your non-English database. This simple test can test whether that's the case.

Problems on Creating INDEX for ORDSYS.ORDDOC type
I have a table 'docs'
CREATE TABLE "TEST"."DOCS"
("ID" VARCHAR2(2048 byte) NOT NULL,
"DOCUMENT" "ORDSYS"."ORDDOC",
"DUMMY" CHAR(1 byte) NOT NULL)
The field DOCUMENT contains a number of documents a mixture of .doc and .pdf files. These where uploaded using the code wizards for the web toolkit. Now I want to INDEX DOCUMENT so I can implement a web search facility.
I'm currently following the xamples on http://download-west.oracle.com/otndoc/oracle9i/901_doc/text.901/a90121/cdatadi3.htm#43365 NESTED_DATASTORE Example (Intermedia Documentation)
I did this
ctx_ddl.create_preference('ntds','nested_datastore');
ctx_ddl.set_attribute('ntds','nested_column', 'dummy');
ctx_ddl.set_attribute('ntds','nested_type', 'ordsys.orddoc');
ctx_ddl.set_attribute('ntds','nested_lineno','source');
ctx_ddl.set_attribute('ntds','nested_text', 'comments');
when creating the index using ntds it is complaining about ordsys.orddoc
create index docindx on docs(dummy) indextype is ctxsys.context parameters('data

since orddoc.comments is a clob I cannot see why there shouldn't be a way to index it. What's the use of storing documents in ORDDOC when you can't search them?? -
ORDDOC and context searching!!
We have a scenario in which client uploads file in the format doc,ppt,pdf into database and is stored as orddoc format.
The version of database used in 9i. The client has a requirement in which he needs to search for a particular text inside the document.
Q1. Is this possible using the Orddoc dataype and ctxsys
We have tried with CLOB datatype and were able to search for a particular string inside the document.
Which is best datatype for this purpose and does oracle has any other tools/methods by which this can be done?Hi Satish,
I followed the procedure in the link
Created the table
CREATE TABLE SEARCHTABLE
SNO NUMBER NOT NULL,
DATA ORDSYS.ORDDOC
Then created the index as
CREATE INDEX DATA_CTX_IND ON searchTable(data.source.localdata) INDEXTYPE IS CTXSYS.CONTEXT;
Latter i upload a txt file and recreated the index. I checked the DATA_CTX_IND$I table and found that no data was populated.
I run the query
CREATE INDEX DATA_CTX_IND ON searchTable(data.source.localdata) INDEXTYPE IS CTXSYS.CONTEXT;
and i am getting the following
ORA-29900:operator binding does not exist ORA -06553 : PLS-306 : wrong number or types of arguments in call to 'CONTAINS'
The same query worked fine for varchar and clob type field, so how can it suddently fail for orddoc?
Note: I am not an expert in oracle.. i just having working knowledge .. and this is first complex thing i am doing -
Setproperties on new ORDDOC gives ORA-6512?
Hello,
I am attempting to convert the CLOBs in an existing table into ORDDOCs in a new table.
I seemed to be almost there. I allocated a new ORDDOC using INIT(), and used writeToSource() on the doc pointer to transfer the text (which I first converted to RAW). The application that accepts this now lists the new document, and displays the text contents.
I now need to set the size (and MIME type, even though the app seems to understand that it's a text document). I called setproperties after writeToSource, and get a set of ORA-6510/ORA-6512 errors. (Included below)
I'd really appreciate any advice!
Thanx and regards,
Arn.

I'll try restating my requirements and problems, and hopefully that will help.
We have an existing table containing text comments in CLOBs. I need to convert the contents of each CLOB into a separate new ORDDOC object in a new table. After this, I will also create a JSP screen that will allow new comments to be submitted, which will also be saved in the DB as ORDDOC objects.
The script I provided was my attempt at the conversion, using doc.writeToSource(). My first question is, is this the right way to go about converting CLOBs to ORDDOCs?
I have a screen that lists documents in the DB. This list includes the document size, which I determine using getContentLength(). For "real" documents - that is, sourced from external files and uploaded using the browser, such metadata is automatically captured. For my new document that is sourced from the CLOB, this information (content length, MIME type) is not automatically captured. I therefore need to set it somehow. I attempted to use setproperties, as althought setMimeType works, there is no setContentLength function.
After your reply, we looked into writing our own plugin, but could not glean from the documentation how to go about this - eg, where and how content length is set.
I hope you can provide further advice on this problem.
Thanx again, and regards,
Arn. -

ORDDoc - Loading Word Document - Please Help
Hi
I am trying to upload the word document (doc format) to the table i have in oracle database. The table has the column of type OrdDoc.
I am using Intermedia Java API to load the word file from my local system to the database. The upload is happening successfully but when i try to retreive the document i see that its empty and even the properties (mimetype, format) of the document are null.
I would appreciate if anyone of you could please tell me what am i doing wrong and how can i upload the file correctly.
Below is more information about table structure and also the java code.
Table Structure
TableName: DocTable
ColumnName Type

PreparedStatement insertStmt = conn.prepareStatement(insertDocRecord_Qry);
insertStmt.execute();

opstmt = (OraclePreparedStatement)conn.prepareStatement(updateDoc_Qry);
opstmt.setORAData(1, docProxy);
opstmt.execute();

PLEASE HELP ME FIGURE OUT WHAT AM I DOING WRONG IN ABOVE CODE.
ABOVE Code doesnt throw an error when executed but when i try to retireve the properties of the document that gets loaded in to the DocTable all i see is null values and 0 content length.
Thanks for your help in advance

e have a scenario to imlpement a context search in a table having the datatype as orddoc.
We have created the table as below
CREATE TABLE searchTable
SNO NUMBER NOT NULL,
Data ORDSYS.ORDDOC,
CONSTRAINT PK_searchTable PRIMARY KEY (SNO )
and then created the context index as
CREATE INDEX CTX_IND_DATA ON searchTable(data.source.localdata) INDEXTYPE IS CTXSYS.CONTEXT PARAMETERS
('FILTER CTXSYS.INSO_FILTER') ;
And latter on upload pdf,doc,txt file to the system and recreated the index by dropping and the recreating.
But when we run a query using contains returns no row is returned.Futher analysis revealed that index table CTX_IND_DATA$I has no text_token which indicates that lexical has done done the parsing of the file.
How can we parse and index a pdf,doc file do we need to specify any filter or any other parameter.
This is the follow up of the below link

What is the difference between these two lines of codes?
String currentFile = null;
String currentFile = "";
Edited by: AMARSHI on Jul 10, 2008 7:07 AMThe reference variable itself, takes up the same amount of space, of course, as all references are the same size. Now, the object on the heap is a different story. With null there isn't one, of course (or if there is there is only one for the entire VM), and for the second a String object will be created in the String pool (once again, only one for the entire VM that every = "" assignment will use). But really, what difference does it make? If there is a difference, it is on the order of a few bytes (at max) for the entire VM, and if this is a concern, your probably doing something else greviously wrong. This miniscule difference should not concern you.
Edit: And "nulling" variables to "save" memory is also not something you should be concerned with. Either the variable will go out of scope and the object garbage collected anyway, or it's in constant use and so will not be taking up any extraneous heap space. If one of those is not the case, you are, once again, doing something greviously wrong. -
I'm running into another problem with the AND/OR filter.
The filter for selecting from object "a" and joining to objects b, c & d
is:
(b.theid==2 || c.theid==2 || d.theid==3) && active=="Y"
The SQL that gets generated is:
SELECT <...>
FROM b t1, d t3, a t0, c t2
WHERE ((((t1.theid = 2 AND t0.bid = t1.id) OR (t2.theid = 2 AND t0.cid
= t2.id)) OR (t3.theid = 3 AND t0.did = t3.id)) AND t0.active = 'Y')
This returns a number of instances of the same a object when some of the
OR clauses do not match. For example, if there's no record
with d.theid=3, then it will do a full join on table d.
Do I need to specify something else to flag these as potentially null
fields so that the filter parser adds that check in? The following SQL
query works
ok if I add some checks for NULL on those join fields:
SELECT <...>
FROM b t1, d t3, a t0, c t2
WHERE ((((t1.theid = 2 AND t0.bid = t1.id OR t0.bid IS NULL) OR
(t2.theid = 2 AND t0.cid = t2.id OR t0.cid IS NULL)) OR (t3.theid = 3
AND t0.did = t3.id OR t0.did IS NULL)) AND t0.active = 'Y')
Thanks,

Mike BridgeHi D,
Thank you for your answer.
I have seriously thought about that solution; but I don't think it's a smart way to do it.
If i do it like that, i need to copy the whole table and paste it inside the if statements.
I have two xml elements that I need to make the decisions on. POH_PO_TYPE & CP_RELEASE_NUM.
POH_PO_TYPE can be: STANDARD, RELEASE or BLANKET.
CP_RELEASE_NUM can be: '' or N
If POH_PO_TYPE is RELEASE AND CP_RELEASE_NUM is not ''
OR POH_PO_TYPE is STANDARD
OR POH_PO_TYPE is BLANKET AND CP_RELEASE_NUM is ''
THEN show table (which contains the whole PO).
It shall show the content of the PO in any of these cases.

Unit Testing, Null, and Warnings
I have a Unit Test that includes the following lines:
Dim nullarray As Integer()()
Assert.AreEqual(nullarray.ToString(False), "Nothing")
The variable "nullarray" will obviously be null when ToString is called (ToString is an extension method, which is the one I am testing). This is by design, because the purpose of this specific unit test is to make sure that my ToString extension
method handles null values the way I expect. The test runs fine, but Visual Studio 2013 gives includes the following warning:
Variable 'nullarray' is used before it has been assigned a value. A null reference exception could result at runtime.
This warning is to be expected, and I don't want to stop Visual Studio 2013 from showing this warning or any other warnings, just this specific case (and several others that involve similar scenarios). Is there any way to mark a line or segment
of code so that it is not checked for warnings? Otherwise, I will end up with lots of warnings for things that I am perfectly aware of and don't plan on changing.

Variable 'nullarray' is used before it has been assigned a value. A null reference exception could result at runtime.
Whether the warning above was thrown when you built the test project but the test run successfully? I assume Yes.
Is there any way to mark a line or segment of code so that it is not checked for warnings?
There is no built-in way to make some code snippet or a code line not be checked during compiling, but we can configure some specific warnings not to be warned during compiling in Visual Basic through project Properties->Compile
tab->warning configurations box.
For detailed information, please see: Configuring Warnings in Visual Basic
Another way is to correct your code logic and make sure the code will not generate warning at runtime.
If I misunderstood you, please tell us what code you want it not to be checked for warnings with a sample so that we can further look at your issue.

Hey guys, just experimenting and remembering how to work with nulls to control cams.
I noticed when I enlarge the null in one dimension, the camera's view also seems to widen. What's happening here? What is that and what am I doing that is causing the camera to "see" differently? I thought the whole point of a null was that it didn't have a physical dimension and was really only about orientation and position?Woahhh hold your horses!
I'm trying to understand the program, not trying to criticize it. I love Adobe and AE. Did it sound like I was trying to pick it apart?
What I'm trying to understand is why when I resize it horizontally, it changes the camera view...and therefore understand how it's changing the camera view. This is an important concept for me to get about this. It's not something I have been able to find in literature or other boards. That's all I'm trying to ask. I'm not trying to argue with it or point out a flaw or something like that, I just don't understand what's going on. Is the camera changing and how when I enlarge the null?
