File Upload PJC questions

File Upload PJC
I have installed the File Upload PJC demo & got it working.
We are using Forms 6i patch 8 with servlet configuration, iAS 1.0.2.2.1 on Win 2000, Oracle 8.173
We want to upload/download files to the server & save them as BFILES in the database. I think I am on the right track but have some questions:
What do I have to change in the PJC to increase the memory so I can upload a file > 4 MB? We will be uploading some large files. I'd also like to ability to select multiple files to upload. I don't know much about Java programming but will learn if this is the best way to accomplish this.
I want to upgrade to Forms patch 12. I understand that it uses Jinitiator 1.3 & that it will popup a dialog when it sees a new signed Jar file & will automatically import the certificate if the user decides to trust it - but I read on the Technet forum there is a bug 2483719 - does this work with patch 12?
We also want to use the Native JVM for IE (when it will work with XP - is this patch 13?). What do we have to change if we create a signed CAB file?
We also need the reverse to download a file to the client - WITHOUT using web.show_document - since this does not always prompt you with a save dialog box & tries to open the file in the browser.
Any ideas will be helpful - thanks.

Laura,
these are many questions in one post and I try to answer it as good as I can
We want to upload/download files to the server & save them as BFILES in the database. I think I am on the right track but have some questions:
What do I have to change in the PJC to increase the memory so I can upload a file > 4 MB? We will be uploading some large files.
As far as I know there is no restriction to the size of the file uploaded to the server. There exist a recommendation of to which size this bean has been tested. Due to the implementation of the Bean there are defined chunk sizes for the data passed, but this does not limit the size of a downloaded file.
I'd also like to ability to select multiple files to upload. I don't know much about Java programming but will learn if this is the best way to accomplish this.
Actually you will have to change the code then. First you need to set a porperty on the file dialog allowing the selection of multiple files. Next you will have to handle multiple files in the bean code. Yes, without Java you will not get there.

The problem is that you use a different (custom) signature for the upload bean, after modifying it, that requires the user to first grant it permissions. The bug means that this currently cannot be handled with Jinitiator 1.3.x. The work around is explained in a Whitepaper on OTN about signing Java Bean in Forms (Forms9i collateral section). There is no dependency to teh Forms patch you use, but to Jinitiator. So yes, teh work around will work there.
We also want to use the Native JVM for IE (when it will work with XP - is this patch 13?).
Possibly. That's the target patch.
What do we have to change if we create a signed CAB file?
You'll have to use the Microsoft SDK and refer to their documentation on how to create and use signed cab files. Shoudl be no big difference though.
We also need the reverse to download a file to the client - WITHOUT using web.show_document - since this does not always prompt you with a save dialog box & tries to
open the file in the browser.
This is a problems with files that the Browser has a MIME type map for. If you download a file with the .gif extension, then this is a known MIME type configured in the HTTP Server. Therefore the Browser recognizes that the downloaded stream is a gif file and tries to render it. You can work around it by making sure that the downloaded file extension is not knwon by the HTTP server (Mime type application/word).

File uploading & Another question

So basically, I'm trying to write a program that downloads a remote text file, changes it, and then uploads it to the remote server again. I've accomplished the first, but I can't figure out how to upload it. I have complete access to the server, but I can only do this through port 80, since it's a school project and my school blocks almost every port. Suggestions?
Edited by: Res on Jun 4, 2011 3:12 PM

Ah, thanks, that looks like it's exactly what I needed. Now, after doing a little more work on the class, two more questions have popped up. The first is this. when I create the scanner to read the file, it throws an Input Mismatch Exception at me (line 97). I have absolutely no idea what's causing that, or even what it really means. You'll notice that the file is specified by its path due to a weird thing with how my files are set up on my comp, but I don't think that's got anything to do with it. The next question is, when I turn it into a jar, will the HTTPClient libraries be packaged with it, or will I need to pull some fancy footwork with that?

Tutorial on file upload/downloads questions

Hi Everyone.
Can you tell me how to clear a field such as the :p2_file_name field? I was thinking you could use :p2_file_name := '' like we do in Oracle Forms but that did not work. I put that code into a pl/sql process. The intent was to clear the field after the user clicked the Submit button.
Can you also tell me the details on what is actually going on in the queries and stored procedures shown in the tutorial?
Thanks.

File Upload / Download - Advice Required

Hi all,
This is really just a general question, looking for advice.
I have downloaded and successfully used the File Upload PJC for Forms 6i - thanks Oracle.
We are looking to use this to download and upload files from or to the client machine, and I am (relatively) confident of reversing the Java components to allow this to happen.
However, we are actually looking to transfer the files from the client machine, to the 9iAS Tier and then to the UNIX (AIX) tier where the database (8.1.7.4) resides - and vice versa.
I have considered a couple of different approaches :
1. Run the Java Server component in the Database JVM to enable the writing/reading of files on the UNIX filesystem.
2. Use TEXT_IO on the 9iAS tier, and UTL_FILE on the Database Tier, to move files between the two tiers.
3. Write the files to / from the Database, and then from/to there into the UNIX filesystem.
Does anyone have any expereince of attempting to implement a similar solution, or information on Oracle documentation explaining any of the above.
Plus, I'm sure I must be missing a trick !
Any other ideas ??
Regards
Marc Ludwig

We have build a similar solution,
for the download:
we use the pl/sql gateway to send the file to the client with the following function:
wpg_docload.download_File(lob_loc);
you could build a pl/sql procedure that accepts an id and selects the blob locater and
triggers this function. the procedure can be called by setting the configuration in your DAD correctly.
that way its easier then rebuilding the whole fileupload utility.
in the webforms you can have a code that opens a new window with an url you give.
the url will point to the pl/sql function and you can pass the id of the record you want to get the blob from.
for the upload to your database:
well, we chose to loose the zip functionality and modify the pl/sql library that comes with it.
instead of using the uploadserver class, you could build a pl/sql function in the database that
accepts the varchar32 strings (which are base64encoded chunks of your file) and appends them to a blob.
the function that could do that would look like:
PROCEDURE APPEND_DATA(P_ID IN NUMBER, P_DATA IN VARCHAR2) IS
bin_data blob;
append_data blob;
raw_data raw(16384);
BEGIN
dbms_lob.CREATETEMPORARY(append_data,true);
dbms_lob.OPEN(append_data,DBMS_LOB.LOB_READWRITE);
select binary_data into bin_data from ibs_physical_doc where id=P_ID for update;
raw_data:= utl_encode.BASE64_DECODE(utl_raw.CAST_TO_RAW(p_data));
dbms_lob.write(append_data, utl_raw.LENGTH(raw_data),1,raw_data);
dbms_lob.APPEND(bin_data,append_data);
dbms_lob.CLOSE(append_data);
COMMIT;
END;
you can increase the chunksize a bit more.
you still have a problem btw that you probably cant upload more then 4-8 mb before you get an out of memory error on the client.
you could solve that by rewriting the client java file to send the file piece by piece on request by the server instead of all the pieces after eachother, and first read a piece of the file and then encode that piece and then send it instead of reading the whole file, encoding it and sending the chunks.
Another option is to use the standard upload possibilties with web pl/sql, and open a new browser window to that window from forms. A drawback of that is that it is not integrated in the web forms program and that you cant see when the upload is finished (no callback). and that you are bound to the default table layout.
one final thing, if you are going to use this, you might want to take a look at using JInitiator 1.3.1.9 if you arent using it already this automaticly sets the signature in the clients database if he accepts it. there is a bug in it, look for it somewhere in this forum. if you are using the sample that comes with forms 6i you will have to replace the fileuploadprogressbar with the one that comes with the forms 9i sample and recompile everything and i think you will have to use JDK1.3.1_03 for that. that means that you will have to modify the make batch file. the command for compiling is different, the classpath is an option when you call javac, also you will have to sign it with jarsigner.exe (in the jdk) instead of the one in the example.
Hope this info is helpfull, if you like to have more specific code, mail me at [email protected]

Question about File upload functionality in Weblogic

Hi,
    We're currently trying to deploy a web application on the weblogic 12c server (via war file). And the app needs to upload a text file onto the a temperary directory within weblogic server. And on the web page side, we use JQuery File upload plugin.
    My question is, on the file receiver side, does weblogic provide any tools to receive the uploaded file and store it?
Thanks very much in advance.

Hi,
Before setting the string or xstring to server->response->set_cdata (string) or server->response->set_data (xstring) try this:
CONCATENATE 'attachment;filename=' lv_filename '.xml' INTO lv_string.
* Setting the filename by default
server->response->set_header_field( name = 'Content-Disposition'
                                      value = lv_string ).
Hope this helps.

JSP : latest JSTL, File Upload from web form Client to Server Question!

I understand that within a JSP, It is possible to read a file from the Client by opening a Stream somehow.
How do I code, within jsp/servlet (non tag) java code inside <% %>
blocks, WITHOUT openening a new connection to the URL, an InputStream from a client web browser form, from a file upload coded using
<input type="file" name="file1"/> ?
I have previously achieved this quite simply with a FileInputStream
with the previous version of JSTL.
How may I do this with the latest version of JSTL, with this index.jsp?
-with a simple text file.
-with a Binary file (with DataInputStream)?

and run this in an index.jsp, use browse to select my text file, and click SUBMIT.
I can use:
InputStreamReader reader = new InputStreamReader(new DataInputStream(request.getInputStream()))
BufferedReader bufferedReader = new BufferedReader(reader);
bufferedReader.readLine();...
However, these is some HTML/POST related content around what multiple readLine();
calls return.
Is there an easy way, like using "${param.file1}",
aside from [http://commons.apache.org/fileupload/|http://commons.apache.org/fileupload/],
maybe using servlet style code, to get the File contents from a remote Client,
to the remote Server servlet engine, AVOIDING ANY SUPERFLUOUS CONTENT,
using version 1.12 of the JSTL, JSP 2.0,Tomcat 6?
Just politely, yes, no, and how?

Question about file uploads

is having a file upload function on a web page a hard thing to do?
i need to do this, but i do not know where to start...
if anyone can help me out/shed some light on this for me that would be greatly appreciated!~!!!
THANKS!

No it is not particularly difficult; I let the user select a file on the client filesystem then upload to the server.
The form ENCTYPE must be multipart/form-data:
<FORM NAME="frmUpload" ENCTYPE="multipart/form-data" METHOD="POST" ACTION=...>
Use:
<INPUT TYPE="file" NAME="srcFile" SIZE="15" MAXLENGTH="40">
In my servlet:
verify:
String contentType = request.getHeader("Content-Type");
if (contentType.indexOf("multipart/form-data") < 0) {
...handle error...
String boundary = contentType.substring(contentType.indexOf("boundary=") + 9, contentType.length());
private boolean TransferFile(ServletInputStream is, String srcFile,
String destDir,String caseNo, String boundary, String errorPage,
HttpServletRequest request, HttpServletResponse response) throws ServletException
File pathName = new File(...);
// If the target directory does not already exist then create it.
if (!pathName.exists()) {
pathName.mkdir();
if (!pathName.exists()) { // did mkdir work?
... do lots more checking ...
boolean xferOK = false;
try {
FileOutputStream fout = new FileOutputStream(...);
byte[] nextBytes = null;
byte[] currBytes = null;
while ((nextBytes = ReadLine(is)) != null) {
if (currBytes != null) {
String snippet = "";
if (nextBytes.length - 10 <= boundary.length())
snippet = new String(nextBytes);
if (snippet.indexOf(boundary) < 0)
fout.write(currBytes, 0, currBytes.length);
else
fout.write(currBytes, 0, currBytes.length - 2);
currBytes = nextBytes;
fout.close();
xferOK = true;
catch (IOException ioe) {
return xferOK;
} // TransferFile()
Hope this helps

Change upload file name with com.oreilly.servlet.MultipartRequest to handle the file upload

1. when use com.oreilly.servlet.MultipartRequest to handle the file upload, can I change the upload file name .
2. how com.oreilly.servlet.MultipartReques handle file upload? do it change to byte ?
what different? if I use the following method?
   File uploadedFile = (File) mp.getFile("filename");
               FileOutputStream fos = new FileOutputStream(filename);
                byte[] uploadedFileBuf = new byte[(int) uploadedFile.length()];
               fos.write(data);
             fos.close();

My questions are
1) when use oreilly package to do file upload , it looks like i line of code is enough to store the upload file in the
file direction.
MultipartRequest multi =
        new MultipartRequest(request, dirName, 10*1024*1024); // 10MB
why some example still use FileOutputStream?
outs = new FileOutputStream(UPLOADDIR+fileName);
    filePart.writeTo(outs);
   outs.flush();
outs.close();
2) can I rename the file name when I use oreilly package?

Well Well Well..
That would not work...
What you have to do is save the uploaded file content on to a location and then pass the fileName as a request parameter to a deidicated which displays the contents of that file.
Just as an example

Calendar & File Upload Components - Threadinar6

Hi All,
This is the sixth in the "Threadinar" series , please see Threadinar5 at
http://swforum.sun.com/jive/thread.jspa?threadID=99473 for details
In this Threadinar we will focus on the
"Calendar" and "File Upload" Components
Let us begin our discussion with the Calendar Component.
Calendar Component
You can drag the Calendar component "calendar component icon" from the Palette's Basic category to a page open in the Visual Designer to create an entry field with an integrated calendar pop-up to help the user pick dates for the field.
You can also drop the calendar on a container component, like a table cell or group box.
After dragging the component to the Visual Designer, you can work with the following useful properties of the Calendar Component:-
General
* id. Type: String
The name of the Calendar component in the page bean and the JSP file.
Appearance
* columns. Type: int
The number of character columns used to render the component. The default value is 20.
* dateFormatPattern. Type: String
The format of the date to be entered by the user. It is not usually necessary to set this property because a pattern is chosen automatically based on the locale.
If you prefer to specify a date format, click the ellipsis button (...) to the right of the property and select a predefined date format from the property editor's list. You can also add your own formats. If you add a format, the values you can enter are limited to some combination of yyyy for the year, MM for the month, and dd for the day separated by separator characters. Typical separator characters are / (slash), . (period), and - (dash). For example, the following date formats are acceptable:
o MM/dd/yyyy
o yyyy.MM.dd
o MM-dd-yyyy
* dateFormatPatternHelp. Type: text
Text that appears below the date entry field and shows the format pattern that the date entry field accepts. If you have not set the dateFormatPattern property, the help text is chosen automatically for you. If you have set the dateFormatPattern property, you should bind the dateFormatPatternHelp property to a localized string that matches the setting for each locale you want to support.
* label. Type: String
A label that appears next to the text entry field, typically describing what the user is supposed to enter.
o Note: The label property is not as flexible as the Label component. You can use the Label component if you want more control over the label's appearance, such as positioning of the label relative to the component.
* labelLevel. Type: int
A number that affects the appearance of the label. 1 (Strong) is larger and bold. 2 (Medium), the default, is smaller and bold. 3 (Weak) is smaller and normal (not bold). This property takes effect only if the label property is set.
* style. Type: String
Cascading Style Sheet rules (CSS level 2) to be applied to the component. For example:
position: absolute; left: 288px; top: 312px
You can enter values directly or click the ellipsis (...) button to use the Style Editor.
o Note: This property overrides any settings in the theme or the project CSS file for this component. If a style specified in this property does not appear to take effect, it is because an area of the component is obscured by a child component that has different style settings.
For a list of CSS2 style attributes, see the web page at
http://www.w3.org/TR/REC-CSS2/propidx.html
* styleClass. Type: String
A space-separated list of CSS2 style classes to be applied when the component is rendered. The style classes must be defined in the project's style sheet or in the theme's CSS file. If you click the ellipsis button (...), you see a list of all styles you can add to this property. For information on adding CSS classes and rules to the project's cascading style sheet, see CSS Editor.
o Note: See the note above under the style property description for an explanation of why a class added to this property might appear to have no effect on the component.
o Note: If you add a CSS style class from the current theme to your project CSS file and you redefine the style class, the change affects all components that use this style class. However, you can add your own style classes to the project CSS file that redefine the default style classes, and then when you add them to this property, the changes affect only this instance of this component.
For the defaulttheme.jar CSS style classes for this component, see Calendar Component CSS Classes.
Data
* maxDate. Type: java.util.Date
The last date that the user can select. The default value is four years from the date set in the minDate property, for a total span of five years.
* minDate. Type: java.util.Date
The earliest date that the user can select. The default value is the value of the selectedDate property, which defaults to the current date if that property is not set.
* required. Type: boolean
If selected, the user must enter a value for the calendar before the page can be submitted. If you add a Message component to the page and link its for property to this component, an error message will be displayed if the user tries to submit the page without entering a value.
* selectedDate. Type: Date
A java.util.Date object representing the calendar date selected by the user. If you right-click the component and choose Bind to Data, you can bind this property to a data provider or object that can process the user entered value on the server.
When the component displays initially, if this property is not set, its value defaults to the current date. If you provide values for minDate and maxDate, you can also provide a value for this property that initially displays a date in that range.
* validator. Type: MethodBinding
Indicates the JavaServer Faces validator that is called when the value is submitted. A validator ensures that the correct value is entered by a user. Choose a validator from the drop-down list. If you choose (null), no validator is called. If you choose a validator, also select the required property to ensure that the validator is used. For descriptions of JavaServer Faces validators, see the list of topics at List of Validators.
o Note: If you define your own validate method, for example, by right-clicking the component and choosing Edit Event Handler > validate, any value you might have set in this property is overridden.
File Upload Component
You can drag the File Upload component "file upload component icon" from the Palette's Basic category to the Visual Designer to create an entry field and a browse button that opens a file chooser dialog on the local system, enabling the user either to select a file or to type a file name into the entry field. When the page is submitted, a copy of the file's contents is sent to the web application.
The component is similar to an HTML <input type="file"> element.
* Note: This component is neither supported by nor available in portlet projects due to security reasons.
* Note: The size of the component in the Visual Designer might not match the size of the component when it is rendered in a web browser, making the component appear to line up correctly in the Visual Designer, but not when the page is rendered in the user's web browser. Also, the rendering of this component can differ depending on the web browser. Be sure to test the component in the web browsers that you expect your users to use. For example, if you add a width setting to the style property that is smaller than the setting in the columns property, Internet Explorer observes only the width setting, while the Mozilla browser ignores it and sets the width according to the number of characters in the columns property.
The File upload component uses a filter, a com.sun.rave.web.ui.util.UploadFilter object that is configured for you in the web application's deployment descriptor. The UploadFilter uses the Apache commons fileupload package. You might need to change these settings in the following two cases:
* The server holds the uploaded file in memory unless it exceeds 4096 bytes; otherwise, the server holds the file contents in a temporary file. You can change this threshold by modifying the sizeThreshold parameter for the UploadFilter filter entry in the web application's web.xml file.
* By default, the File Upload component can handle files up to one megabyte in size. You can change the maximum file size by modifying the maxSize parameter for the UploadFilter filter entry in the application's web.xml file.
o
A negative value for the maxSize parameter indicates that there is no file size limit. Setting the parameter to a negative value is not recommended for security reasons. For example, if you allow unlimited file sizes, a malicious user could mount a denial of service attack on your site by using extremely large files
* To change the settings for the UploadFilter object in the web.xml file:
1. In the Files window, expand project-name > web > WEB-INF.
2. Double-click the web.xml node to open the file in the XML editor.
3. Click the Filters toolbar button.
4. In the UploadFilter section under Initialization Parameters, you can change the values for the maxSize and sizeThreshold parameters.
The contents of the uploaded file, together with some information about it, are stored in an instance of com.sun.rave.web.ui.model.UploadedFile. By using this object, you can get the content of the file as a String or write the contents to disk, as well as get properties such as the name and the size of the file. In the interest of conserving memory, the contents and file data are only available during the HTTP request in which the file was uploaded. To access the contents of the uploaded file, bind the uploadedFile property to a bean property of type com.sun.rave.web.ui.model.UploadedFile. Have the setter or an action method process the file.
The UploadedFile interface has methods for getting the name and size of the file, determining the file's MIME type (such as text/plain or image/jpeg), getting the file's contents as bytes or as a String, and writing the contents to disk. To learn more, in the Java editor, right-click on UploadedFile in a declaration statement and choose Show JavaDoc from the pop-up menu.
* To set the component's properties, select the component and edit its properties in the File Upload Properties Window.
* Right-click the component and choose one of the following pop-up menu items:
o Edit validate Event Handler. Opens the Java Editor with the cursor positioned in the component's validate method so you can insert code to validate the value of the component.
o Set Initial Focus. Gives this component focus when the user opens the page.
o Auto-submit on Change. Causes the form to be automatically submitted if the value of the component changes. Sets the component's JavaScript onclick property to common_timeoutSubmitForm(this.form, 'component-id');. At runtime, this code causes the form to be automatically submitted if the user changes the component value. Once the form is submitted, conversion and validation occur on the server and any value change listener methods execute, and then the page is redisplayed.
A component configured to Auto-submit on Change can use virtual forms to limit the input fields that are processed when the form is submitted. If the auto-submit component is defined to submit a virtual form, only the participants in that virtual form will be processed when the auto-submit occurs.
o Bind to Data. Bind the component's text property to an object or to a data provider. For more information, see Bind to Data Dialog Box.
o Property Bindings. Bind any of the component's properties to an object or data provider, such as the uploadedFile property to a bean property of type com.sun.rave.web.ui.model.UploadedFile.
o Configure Virtual Forms. Enables you to add the component to a virtual form.

File Upload problem: JSF, IBM WPS and Portlet - Please HELP Vey Very Urgent

I want to upload a file from the front end using JSF and Portlets deployed on IBM WebSphere Portal.
I have used Apache's commons file upload functionality as the file upload provided in JSF doesnot work with portlets and the action event is not invoked If I keep enctype="multipart/form-data". So I included 3 forms in my Faces JSP file.
1) h:form = For displyign error message on screen
2) html:form = Include the enctype="multipart/form-data" and the input type file for uploading. And a submit button
3) h:form: Here I have a command link which is remotely excuted on click of sumit button in my html form. This is to invoke the action event in the pagecode to get the bean value from the context.
Now in the my doView method in the portlet, isMultipartContent(httpservletrequest) always returns null as the content type is text/html and not multipart. Onclick of the submit button in the the html form I am calling a javascript function which sets the __LINK_TARGET__ to the command link in the 3rd h:form which will call the page code.
The problem here is action is invoked only when I return false from the above javascript else it will trigger for the first time and from second time onwards it will not invoke the action event in the pagecode method. Whent the javascript function returns false, the content type is always text/html. However if I return "true" from the javascript the content type is multipart/form-data, but the action is not triggered for the second time. So basically when the javascript functions returns true, for the first click everything works perfectly. When it returns false, the content type is text/html, but the action is invoked in the page code every time.
Returning always true would solve my problem with the content type, but the action with the command link will not get invoked always as its some type of problem with h:commanLink :(.
I guess I gave too much info. Heres my code stepby step.
Can somebody please tell me , how I should also invoke the action in the page code and get the content type as "multipart/form-data" at the same time.

Thanks.

one more question. Is there a way where I can submit two forms ?
Thats is submit 2nd form only when the first form is submitted.
I tried this it works.
function formSubmit(){
document.form1.submit();
alert();
document.form2.submit();
But If I dont put an alert(basically it disables the parent page) in between, only the second form is submitted.
If I put a delay of say 3 seconds in between then it will throw a SOCKET CLOSED error in the code triggered due to first form submit.
Thus disabling the paresnt page for a few seconds is reolving my problem.
Any ideas ?
Well Basically when the Alert pop's up the parent page "STALLS" and thus the form2 does not submit till I click on OK, Is there a way I can stall the browser/Parent JSP page using JAVA SCRIPT ??

Reliable file upload using JDev, AS and other

Hello,
I'm not sure this is the right place to post this message, sorry if I was wrong to put it here.
The question is our company is developing software, for active data exchange with other systems. We decided to exchange in xml format, by means of both web services and web interface (so that exchange could happen both automatically and on user request). We use JDev to develop, Oracle AS to deploy application. Systems we exchange can use various platforms, in fact, it doesn't matter what exactly they use. The question is we need a reliable way to exchange large (sometimes small, but can be 1Gb or, for example, 10Gb) files, maybe with appropriate security, so that it could continue if something happens with network connection.
One simple decision is to have a web service that accepts, for example, 100K at a time, and another service continuously calls it until file is transfered. So it can check response code. But are there better decisions? I think, there are libraries or smth like this?
Thanks in advance, believe, it's a right place to get help.
Valeriy

Another, simpler (we think), such package is Jenkov HTTP Multipart File Upload. It's a servlet filter which can work in front of both servlets and JSP's. The servlet filter parses the uploaded file and stores it temporarily on the servers disk. When the servlet or JSP executes afterwards, it can obtain all the information about the file, from the request attributes. There is a decent manual for HTTP Multipart File Upload on the website.
Just search for "Jenkov HTTP Multipart" on Google and you'll find it. HTTP Multipart is free, open source, Apache Licsense.

Unable to install File Upload Utility in AIX system

Hello,
I installed the Forms File Upload Utility, through CGI, following the steps described in the html
document provided with the utility. That is:
- i copied the files UploadClient.jar.sig and UploadServer.jar to the directory
/ias102/6iserver/forms60/java;
- i edited the .profile file, for the variable CLASSPATH to include the forms60/java directory:
CLASSPATH=/ias102/6iserver/forms60/java:/ias102/6iserver/forms60/java/UploadServer.jar:/ias102/6iserver/discwb4/classes/locator.jar:/usr/java131/jre/lib/rt.jar:
- i edited the .profile file, for the variable PATH to include the requested directories (Forms \bin and \bin\classic):
PATH=/ias102/6iserver/lib:/ias102/6iserver/bin:/usr/java131/jre/bin/classic/:/us
r/java13
1/bin:$PATH
(i also tried editing the CLASSPATH and PATH variables in the forms60.sh and forms60_server files)
- on my machine (client machine) i installed the PJC.x509 certificate;
After this installation, i included the Demo Form provided with the utility in my test application, and then i executed
the form.
I tried to upload a file but i got the following error: "FRM-40735: WHEN-BUTTON-PRESSED trigger raised unhandled exception ORA-06508"
I looked in the html document, in the "Troubleshooting" section, and i did a test pressing
the Key-Listval (Control+L by default), that would pop up a dialog containing
the current CLASSPATH, but instead i got the following error:
"FRM-40735: KEY-LISTVAL trigger raised unhandled exception ORA-105100."
In the html said that "If this fails then this is because Forms cannot instanciate any Java code
at all".
Do i need to add any more environment settings?
Thanks, Jorge

There are probably several environment variables which need to be set in order for the Forms runtime to communicate with Java. However, to where they point will depend on which Java home you choose to use. For Forms 6.x, you must use the equivalent of JDK 1.1.8 or 1.2.2. These versions are included in the Oracle home. If you try using a newer version (like the one installed on the OS) you will likely have problems.
Verify these env variables point to the appropriate locations to use the jdk/jre in the Oracle Home:
PATH
CLASSPATH
LIBPATH
LD_LIBRARY_PATH
JAVA_HOME
Additionally, ensure that your CLASSPATH includes references to the following jar files:
importer.jar
rt.jar

File upload demo application in 2.0

Hi!
I implemented the file upload application from the demo applications with the standard table HTMLDB_APPLICATION_FILES. It works very fine. Thanks for sharing this code.
BUT I was unable to implement a custom table, because I could not locate the insert-function (as described in the tutorial). It is no known process on any of my pages.
Could you help me finding it?
(And is a file always stored as blob, or could it be a clob as well?)
My main motive for this question is to gain inside knowledge in building some crude filerepository. We receive plain-ascii-data files via ftp and I have to import their data into a table.
I do not want to go through all this 'reading OS-directory with java, opening files as external tables, moving them with utl_file', if I simply could
a) receive the file directly as a clob in my table
b) get the necessary data with sql
c) handle all archiving, file renaming directly by updating a table
Beside application express's file upload (speaking only http), the is a XML repository which 'speaks' ftp and http.
Does someone have experience with uploading non-xml files and storing them as clobs?
Thanks,
Michael

Hello Michael,
I believe the reference in the demo tutorial is to Insert process (not function). This is probably the process defined on page 8-6, step 4a of the "Create a process to insert information" section.
Basically you can upload and store files in CLOB. For my self, I only did it with XML files, but I don't see any reason not to do it with other types of files.
I think that in order to work with non-structured files (like ASCII) you should learn more about Oracle Text. Apex is also using this product. Search this forum for "oracle text" and continue from there.
Hope this helps,
Arie.
