Basic Questions on Spaces, Tabs and File Uploads

hi, new to the language. I have some data that has multiple spaces (not fixed) or multiple tabs as delimiters. How do I recognize the delimiters? Was easy in perl!!
Another question, am trying to upload files to the application. Is there any elegant way to upload multiple files? Or even specify a directory on the client and have the application read the directory and upload all files in the directory?
Thanks in advance

hi, new to the language. I have some data that has multiple spaces (not fixed) or multiple tabs as delimiters. How do I recognize the delimiters? Was easy in perl!! String.indexOf(" "); <---- double space
Another question, am trying to upload files to the application. Is there any elegant way to upload multiple files? Or even specify a directory on the client and have the application read the directory and upload all files in the directory? <--- FileSystemView is JFileChooser's gateway to the file system. Since the JDK1.1 File API doesn't allow access to such information as root partitions, file type information, or hidden file bits, this class is designed to intuit as much OS-specific file system information as possible.

In Files, How to read and write spaces,tabs and newlines

Love..........
After having read a file into a string, when
I use this string in TextArea's setText()
method. Text Area do not care for spaces,tabs,
newlines. if I print same string using println()
out put has lines,spaces and tabs
----why-------
Similarly when I write to a file getting text
from Aextarea,out put file also produce same
result .

First, if you would like to create a text area that wraps the text, instead of just running on and on, you need to specify, when creating the text area, that you do not want a horizontal scroll bar. For instance:
textArea = new TextArea("", 30, 60, TextArea.SCROLLBARS_VERTICAL_ONLY);
Why does println() cause a newline? Because println means print line... as in, it will print the text, then give a carriage return and line feed value, causing a new line to be created.

Basic questions about Bigdata, NOSQL and Hadoop

Hi,
I've basic questions related to Bigdata. (I've googled it but still wants to confirm with experts)
Please correct me if I am wrong on below.
1) As far as I know big data is collection of unstructured data. Even we can store relational data as well.
2) NOSQL is an Oracle product to handle bigdata (un structured data and relational data as well)
3) Hadoop is the only one frame work which is avilable in market to manage the bigdata.
What are the other database systems we have in the market to manage the bigdata.
Cheers,
Suri

Hi Suri,
1) "Big Data" does not have a crystal clear, black and white definition.
It is generally characterized as being the processing and management of an amount and type of data that makes a specific workload on that data slow and/or expensive.
Most commonly, Big Data involves processing and management of unstructured data of large volume and the typical technology used to store/process it is Hadoop, However, on occasion a NoSQL database will also deal with unstructured data.
Big Data is also seen often in the form of simple, semi-structured data of both large volume and/or large velocity and the typical technology used to store/process it is a NoSQL database. However, on occasion Hadoop will also deal with semi-structured data of large volume.
In some cases, Big Data is seen in the form of highly connected data that will be manipulated by advanced algorithms that will need to touch a lot of the data and the typical technology used to store/process it is a Graph type of NoSQL database.
2) NoSQL is a category of database technologies most often dealing with the issues as outlined in bullet 2 above. The Oracle NoSQL Database is oracle's product in the NoSQL category of database technologies. It does NOT store relational data. When using NoSQL relations between the data must be managed within the application code.
3) Hadoop and NoSQL booth manage Big Data, but different aspects as discussed in (1) above. Hadoop is a batch based, slow processing data technology, but the "slow" is relative because it can process very large amounts of data, so minutes is commonly seen as fast. NoSQL is a near real-time data processing technology and typically deals with Big Data where access times are in the single digit millisecond range.
Hope this helps,

Basic questions about connection sharing and radio mode

I just got TC and have a couple of basic questions.
At home I have a D-Link ADSL modem/router (no wifi) plugged into the wall, and would like TC to provide wifi. I've connected the WAN port to some LAN port of the router and everything works fine. The intented usage of the setup is wifi-only. Would you recommend TC to do DHCP/NAT? Or is Bridge mode better? In the latter case I don't fully understand who's routing the wifi network (though it actually works).
Second question is about radio mode. My wife has an iBook G4 that is not capable of talking 801.11n, so I selected the n mode compatible with b/g. In that mode my black MacBook will still be able to talk 801.11n with TC? The iBook has very low usage, it is fine that computer uses 801.11g for TC, but I'd like the MacBook to go full-speed. (If that's not possible I'd ponder purchasing an 801.11n adaptor of some sort for the iBook.)

Would you recommend TC to do DHCP/NAT? Or is Bridge mode better?
It doesn't matter.
In the latter case I don't fully understand who's routing the wifi network (though it actually works).
The D-Link modem/router.
In that mode my black MacBook will still be able to talk 801.11n with TC?
Yes. It will only suffer lower bandwidth if the iBook G4 is actively connected.

WSRP and File Uploads

Hello,
I am using BEA 8.1 SP4.
I am trying to find out the status of being able to do file uploads in portlets being displayed remotely. I have a JSR-168 portlet which simply does a file upload to the server. The JSP page that renders the content contains:
<form name="ont_mainform" method="post" action="<%=portletURI%>" enctype="multipart/form-data">
When I have the same portlet running remotely in another portal via WSRP, I get the error:
java.lang.Exception: The request does not contain a multipart/form-data or multipart/mixed stream. Content type = null
Does anyone know whether WSRP is not able to handle file uploads in the web service call just yet or is there something I need to do to get it to work? Or is this a container issue?
Thanks for any thoughts - Peter Len

Hi Peter,
By default, the consumer reads the MIME message, sends it to the
producer over SOAP, and the producer then recreates the stream for the
portlet. So, the boundary strings and the headers may not be the same.
WLP8.1SP4 also supports a mode wherein the uploaded data is transported
as a MIME attachment. For this enable accepts-mime to "true" and
transport="attachment" on the producer side in wsrp-producer-config.xml.
Here is a sample snippet.
<markup secure="false" rewrite-urls="true"
transport="string" accepts-mime="false"/>
Can you try this configuration and see if it works differently.

Subbu,
This is a re-copy of my last reply as it looks like the line breaks did not take.
Okay, I have run across something else which is another oddity. In the code that deals with the commons-fileupload.
I have the following code:
int boundaryIndex = contentType.indexOf("boundary="); byte[] boundary = contentType.substring(boundaryIndex +
9).getBytes();
InputStream input = req.getPortletInputStream(); MultipartStream multi = new MultipartStream(input,
boundary);
boolean nextPart = multi.skipPreamble();
// some print statements
When running the portlet locally I get:
Boundary Index: 21
Boundary Array: [B@1cccea2
InputStream: weblogic.servlet.internal.ServletInputStreamImpl@111fae9 MultipartStream: boundary='[B@17002a1' bufSize=4096 skipPreamble?: true
When running it remotely I get:
Boundary Index: 21
Boundary Array: [B@737d8a
InputStream: com.bea.wsrp.producer.container.MultipartInputStream@3708e6 MultipartStream: boundary='[B@12952ec' bufSize=4096 skipPreamble?: false
There seems to be a difference in what the InputStream object is. The key here is that the skipPreamble boolean is false for the remote portlet and that essentially keeps the code from downloading anything. Not sure if this is a commons-fileupload thing or not. Do you know of another fileupload API that you know works with remote portlets?
Thanks - Peter

OrdDocDomain and File Upload

Hello All,
JDeveloper 11.1.1.5, ADF Faces, ADF BC
I have a database table with a ORDSYS.ORDDOC column. I have now gotten file upload to work and the document gets saved to the database correctly.
There are a few problems though:
1) Even with a newly created record, the inputFile component displays an "Update" button instead of a "Browse" button. The file name is displayed as "{}". This isn't user-friendly and tends to confuse the users.
See: http://dox.bijesh.info/newrec.jpg
2) When the user revisits an existing record the inputFile component has the same behaviour and the file is displayed as "{}" rather than the filename.
See: http://dox.bijesh.info/existingrec.jpg
3) I added an af:media component with the source set to "#{bindings.DocAttr.inputValue}" and rendered as a link. Clicking the Play Media link results in a 404 error looking for "faces/{}"
What am I doing wrong?
Is there a definitive tutorial from Oracle about using OrdDoc in an ADF application?

thease are the configurations before you use af:inputFile in the page
http://myfaces.apache.org/trinidad/devguide/fileUpload.html
for should have useupload=true
<af:form usesUpload="true"/>add the following entry to your WEB-INF/web.xml file:
<filter>
<filter-name>trinidad</filter-name>
<filter-class>org.apache.myfaces.trinidad.webapp.TrinidadFilter</filter-class>
</filter>Second, map that filter to process all FacesServlet requests. For example, if you've named the FacesServlet "faces":
> <servlet>
> <servlet-name>faces</servlet-name>
> <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
</servlet>then use the following filter-mapping:
<filter-mapping>> <filter-name>trinidad</filter-name>
> <servlet-name>faces</servlet-name>
> </filter-mapping>

Authentication and file upload

Hello,
Problem definition:
One of servlet is protected by Apache's LOCATION directive. According to my observation, after my HTML form is posted, username/password pop-up menu doesn't appear immediately. I'm not sure, but I guess all HTML form data including the uploaded file content are sent to web server before usernam/password check. Because I'm wating for a long time if HTML form includes a long file. After a while, web server requires username/password. Until this time, there is no file saved to server. After user enters username/password file upload starts.
Question:
- is my observation correct ? If an HTML form is posted, is entire data including file content posted ?
- is there a way to enable username/password check before posting file in HTML form ?
thanks in advance...

A small correction:
- is my observation correct ? If an HTML form is posted, is entire data including file content posted before username/password check ?

Distinguish between manually entered file and file uploaded by conversion

Hi ,
I am involved in a conversion wherein i have the requirement to get those file uploaded form front end.
Is there any distinguishing column to know as to whether the file loaded in fnd_lobs or fnd_documents_tl are from front end or through conversion.
Please let me know if any of you have a solution to it?
Thanks and Regards,
Amar Deep Gautam

You can consider using the upload_Date column.
OR
You can consider a naming convention for the file name (such as CONV_PO_TERMS.dat).

PDF forms and file uploads

I realize that FormsCentral does not currently support file uploads (aka attachments) when using a PDF form to submit. In several of this places I've read this, it seems to imply that PDF forms to not support file uploads. I also noticed that when a PDF form is enabled for use with FormsCentral, the submit format is "HTML" (i.e., URL-encoded, or multipart/form-data when file attachments are present). PDF forms do indeed support file uploads in the same way that HTML forms do, so I'm wondering why FormsCentral doesn't allow them with PDF forms. On the form side, all it takes is setting up a text field so it can be used for file selection (Field Properties > Options > [Scroll Long Text] && [Field is used for file selection]) along with the field.browseForFileToSubmit JavaScript method (http://livedocs.adobe.com/acrobat_sdk/9.1/Acrobat9_1_HTMLHelp/JS_API_AcroJS.88.734.html) with a button. The data is sent in the same format as with an HTML form, so it isn't difficult to process. What's the reason for this limitation, or will this method in fact work? I know that PDF forms can also support attachments two other ways, either as actual file attachments to the PDF or as a files attached as a comments, but these types are not what I'm asking about.

Randy,
Thank you for the reply. I am a bit surprised though, as I recall about 10 years ago modifying a CGI program designed to process HTML form submissions that could included file uploads. I didn't have to change any of the code that parsed the input when it was used with a PDF form that submitted as "HTML", since the format of the POSTed data is the same. I did have to modify the code that generated the response (to return an FDF), but that's a different matter. I think it would be great to support file uploads with PDF forms, as well as submitting as FDF.

Question re Accessing catalogues and files from an external hard drive in Elements 6.

Having just acquired an ehd, I have successfully carried out a trial back up of an Elements 6 2000 picture catalogue from an XP based PC, using the Elements 6 full back-up process. This process is intended to be used eventually to transfer this and other catalogues onto a new Windows 8 PC installed with Elements 11.
However, in the interim I would also like to be able to access the picture files and the catalogue data on the ehd from a Vista based laptop which also has Elements 6 installed. Can you please advise how to do this without carrying out a full restore process that would load all of the files onto my laptop's hard drive.
In transferring the picture files to the ehd I also seem to have lost the original file structure that was on my PC, as folders have been renamed numerically and are all held individually in the main folder of the ehd. Whilst this doesn't matter too much whilst the files remain on the ehd, provided the catalogue still knows where to find them, has the original file structure been permanently lost, or can I recreate it when I eventually restore the files and catalogue on the new Windows 8 PC?
I'm anxious to get this process right as I have a much larger catalogue to similarly back-up and transfer, once I have acquired the new PC, and was hoping to be able to similarly access this catalogue by my laptop from the ehd as there is insufficent hard disk space on my laptop to hold all the 20,000 files involved.
Please help
Gardener 179

Thanks for your help re my original questions.
Reassured regarding not having lost the file structure of my pictures, and bearing in mind the relatively small catalogue I had backed up, I thought that rather than restoring by leaving the picture files on the EHD, I would after all restore to the laptop hard drive, as a trial run before dealing with my main catalogue.
The restore was successful but raised a number of further issues that I would appreciate your advice on:-
1) The original catalogue name was not used in the restoration process. The restored catalogue on the laptop has simply been named "Pictures". Is this normal and if I now rename the restored catalogue will this create problems with any subsequent supplementary backups of the catalogue?
2) In restoring the catalogue I heeded the Adobe Help and specified the Vista folder C:\Users\Maurice\Pictures as the location for the picture files rather than simply restoring the original XP folder structure. However, since I also wanted to retain the lower level folder structure of my XP files (which are basically date files) I then specified to "Retain the Original Folder Structure". This has resulted in the full XP folder structure being created within \Pictures on the laptop.
Is it possible to avoid this situation occurring, or will I have to remove the unwanted XP sub-folder structure from the laptop and reconnect the thumbnails in the Photoshop catalogue to the new file locations? Also if I have to move files in this way will I once again have problems with any subsequent restorations of the same catalogue?
I have also a couple of supplementary questions re the initial backup to the EHD which I have now looked at more closely:-
1) The original XP catalogue has 1853 picture files, (and this is identical to that subsequently restored on the laptop), yet in backing up the catalogue to the EHD it seems that in excess of 2200 picture files have been created. Why is this?
2) As previously advised the pictures are held on the EHD numbered sequentially as "b000001" etc, and due to my selecting the EHD top level root folder as the destination for the back up are held in F:\. Should I have created a new folder, say "Backup 1" on the EHD, and then specified this as the destination folder, as I am concerned that on backing up further catalogues the existing picture files will get overwritten and the Photoshop Backup and Catalogue files confused with previous backups? If so can I move the existing back up files to a new folder now without causing any problems?
Finally could you confirm what would have happened to the folder structure on the EHD had I carried out the Restore process by locating the picture files on the EHD but retaining their original file structure. Would the picture files have been copied into their original file structure for use by the restored catalogue and the duplicate backup files left unaltered, or would the backup picture files have been replaced by the restored file structure? Also would the "catalogue file" be transferred to the Laptop C:\ drive in this process or would this also stay on the EHD and be accessed from there by Photoshop?
Sorry for all the questions but I really want to fully understand what is going on before risking doing anything to move my main catalogue.

Some basic questions about foriegn key , and relationships.

Hi
Thank you for reading my post
I read some documents about foreugn key and tables relation ships.
but i still can not understnad some stuff.
1-when we have a foreign key , we have two tables that we want to relate them together
in a way that one of ? table columns forced to be a value from ?? table column.
what is name of those two tables , i saw , child-parent , ..... which confuse me.
can some one please tell me correct name of those two tables ?
2-some times we need some kind of master details relation like :
one-to-many : i this case MANY table will have a column to point a record in ONE table , can this relation be a foreign key relation ?
3-we can achieve many-to-many relation only by using a helper table to host both tables primary keys in a record to relate them together.
can you point me to some resources that help me to find answers to this questions ?
or explain them to me ?
thank you for your time.

These are critical database basics that you need to understand. I would seriously recommend getting some study in, because proper relational database design relies on the basic principle of data and relationships and a process called normalization.
In reality, you only really need one gigantic table to host data. It would include everything you would want to know about something - let's take a sales order for example. You would have to record the customer's name, address, etc. along with every item they ordered, etc. You would have a HUGE table full of data that appeared over and over and over again. This is bad design for two basic reasons: it is difficult to query, and it is very easy to have minor mistakes like capitalization or alternate spellings that prevent things from matching up properly. For example, let's say Bob orders 40 widgets and 40 digits. In our hypothetical table, we could put it in as Bob - 40 widgets and Robert - 40 digits. See how confusing this can get even in a simple example? And let's say you wanted to correct all of Robert's orders to say Bob and you found out there were 40 orders from "Robert" How would you know which ones to change?
The process of normalization helps to reduce the chance for these types of errors in addition to creating a good basis for indexes. You normalize the data by creating sets of parent/child tables with a "key" value to match them. In our hypothetical situation, you could create a table for orders and a table for customers. In the customers table you give all the detail for the customer in one place, and you assign each customer a unique number or ID. In the orders table we add the customer ID (NOT the name) and we ensure that we are getting the customer we want, in addition to saving a lot of space and eliminating redundancy. In our example, the customers table is the "parent" table and the orders table is the "child" table. The child table references the unique entries in the parent table via that id. That reference is referred to as a foreign key. The foreign key in the child table points back to the original and complete record in the parent table and eliminates the redundancy of keeping all that extra data for every order. Foreign keys in child tables always refer to a primary/unique key in the parent field.
That help?

Removal of TABS from File Upload

Hi all,
I made an upload of a local file with TAB spaces in an internal table .I am required to remove the TABs from the records.I tried to used command REPLACE '/h' by single space, where '/h' being the TAB , but it did not work.

Newbie Question On Library Creation and File Duplication

I'm new to iTune's hard drive file organizing structure, so bare with me.
I have a single directory on Hard Drive 2 (HD2) called "Music". When I create a music library in iTunes from that music directory source, iTunes appears to create its own new directory in "Macintosh HD/Users/iTunes/Music" (HD1) and thus I now have duplicate directories of music on two different hard drives, HD1 and HD2. Add Time Machine to this mix (which backs up both drives) and I now have four directories with duplicate music. Nice.
Okay. So, assuming this is the case (and please correct me if I am wrong), then my question is, once I create a Library via iTunes program, can I now delete my original HD2/Music directory of files since iTunes is referencing its newly created directory in HD1? Or, is there some sort of association still going on and I must live with the duplicate directories and subsequent quadrupled directories? (Which I know I can selectively exclude some stuff from Time Machine, but it is easier to back up everything.)
Thank you in advance for your input and advise.

Yes once music has been added to iTunes you can remove it from its original location with way you have iTunes set up at the moment.
On the other hand you could change the iTunes preferences so that it does not copy files into the iTunes library, instead it leaves the files were there where and points to them.

Very basic questions on JAX-RPC and wscompile

Hello,
well, I have this tool that generates java packages. The thing is that this tool needs now to generate JAX-RPC compliant java packages. To verify its compilance, I am using wscompile 1.1.3 build R1 and Sun AS Edition 8.2.
My questions are:
- In the generated packages, there might some classes with no attributes at all :P(remember that I am handling automatically generated classes). When running wscompile to generate the corresponding WSDL, I am getting "invalid type for JAX-RPC structure", even if it has a default empty constructor. I know it looks stupid, but I could not find anywhere in the JAX-RPC specification saying that for a class to be jaxrpc compliant, it must have at least one attribute. Any idea?
- It might be the case that I have same class name in different packages:
mypackage.structures.messages.A
mypackage.structures.segments.AWhen generating the server stub, I am getting:
Duplicate type name "{urn:mynamespace}A" for java type "mypackage.structures.segments.A" found.
Is there a way to tell wscompile to keep the class package name for every class when generating the wsdl? Or is it always building all the classes together in the package specified in the service/packageName within the configuration xml file?
Thanks a lot in advance for any help.

1. Does predictive text only work in the SMS app, or does it work in the apps for email, writing notes, etc?
It works with Safari, the Mail client, the Notes app, and with the SMS app.
2. Can you turn the predictive text off? (I find it wildly irritating, because I know far better what words I want to write than a pesky phone does!)
Yes.
3. Having email sent to a mobile is a whole new world for me! Do I need to subscribe to MobileMe at £££ per month, or is there another way of having email from my three accounts forwarded to my mobile?
You can access any IMAP or POP account with the iPhone's Mail client, and access multiple email accounts. I currently access to email accounts with the iPhone's mail client - my MobileMe account, and a business POP account. You can access all 3 of your email accounts with the iPhone's Mail client.
