How to use PJC

Hello Every one
I really need your help to guide me to how to use the PJC in my form.
I have downloaded the forms9iDemos9_0_0_1 zip file from Oracle site ,but I don't know how to use them .
Please help and thanks in advance..

Thank you friend for replaying .
It is really strange to tell you that all files that have been downloaded are just JAR Files when they are extracted to my Laptop and vise versa if they are extracted in other PCs (The HTML files are shown ) and I don't know what the reason is.
Any way ,when I read the instructions of how to use the calendar Java Component ,It tells me to first create a normal Forms bean area!!!
Would you mind telling me what a bean area is and how to do so? Is it the small icon shown on form tools menu?
I am somewhat talkative ,But please help.
Thanks for every thing(past posts)

PJC how to use

Hi
I never use PJC and have no idea how to use.
i m using developer 6i on web and now i want to use PJC for change button look like rollover button.
can any one give a step by step guidance?
best regards
mashal

If you already have a PJC that someone else has written all you need to do is to set the implementation class property on the item that you want to use the PJC for. For example - create a normal button on the canvas, and then change it's implementation class property to point at the fully qualified Java class name of the rollover PJC e.g. oracle.forms.demos.enhancedItems.RolloverButton.
You also have to ensure that the JAR file containing the PJC is downloaded with the forms JAR file so you'll need to tweak the formsweb.cfg to add the PJC jarfile for download.
Finally the PJC may need configuring which you'll do according to it's documentation using the set_custom_property build-in from PL/SQL.

How to use the implementation class in propetty pallete

Hi,
I am using forms 10g....I have to insert horizontal scroll bar in text item..
I have only class files instead of jar files ...how cani place the class file instead of jar file...
How to use the implementation class in property palette to display the PJC
Thanks,
Ansaf.

The Implementation Class must reflect the full name of the class. For instance, if the full class name is : xx.yyy.zz.class_name, then put this in the Implementation Class property of the corresponding item.
Also, the class must be stored in the equivalent directory structure, so that, in my example: <DEV_HOME>/forms/java/xx/yyy/zz

Read image using PJC

Hi,
We are converting Oracle Forms from 6i to 11g. We have some forms that use read_image_file to read image. It was .bmp file and now we can only use .gif/.jpg file on web and the image is very blurry.(we use the same .gif source file for image and icon for icon buttons, the icon is very sharp)
I tried to use PJC to read the image and image is very sharp now. I am able to read the image from local drive, like c:\my_image.gif while testing from my local PC. I would like to know how to read image from application server, where put the file and what configurations needed.
Or any solutions are welcome. I am new to Java, please help.

Hello,
I totally agree with Mark. As soon as you have created a virtual directory on the Forms server, you can reach the files stored in the corresponding physical directory.
Here is some code to get the Forms HTTP server URL (assuming that you pass only the virtual directory as file argument e.g: /forms/images/my_image.jpeg)
        String s = (String)value ; // full filename
        try {
          if(s.startsWith("http:") || s.startsWith("ftp:")
          || s.startsWith("www.") || s.startsWith("file:") || s.startsWith("/forms")) {
            initialURL = s ;
            URL url = null ;
            if(s.startsWith("/forms")) {
              // getting the Forms Main class
              try{
                Method method =
                   m_handler.getClass().getMethod("getApplet", new Class[0]);
                Object applet = method.invoke(m_handler, new Object[0]);
                if (applet instanceof Main) {
                   formsMain     = (Main)applet;
                   String sDocBase = formsMain.getDocumentBase().toString();
                   int i = sDocBase.indexOf("/forms/") ;
                   sDocBase = sDocBase.substring(0,i);
                   initialURL = sDocBase + s;
              }catch(Exception ex) {System.err.println(" !!! ReadImage() Unable read the image\n\t"+ex.toString());}
            url = new URL(initialURL);
            // get the image there
        } catch(Exception ex) {
          System.out.println(" !!! ReadImage() Unable to read the image " + s + ": " + ex);

Can't figure out how to use home sharing

Since the latest couple iTunes updates, my family and I can not figure out how to use home sharing. Everyone in our household has their own iTunes, and for a long time we would just share our music through home sharing. But with the updates, so much has changed that we can no longer figure out how to use it.
I have a lot of purchased albums on another laptop in the house, that im trying to move it all over to my own iTunes, and I have spent a long time searching the internet, and everything. And I just can't figure out how to do it. So.... how does it work now? I would really like to get these albums from my moms iTunes, onto mine. I would hate to have to buy them all over again.
If anyone is able to help me out here, that would be great! Thanks!

The problem im having is that after I am in another library through home sharing, I can't figure out how to select an album and import it to my library. They used to have it set up so that you just highlight all of the songs you want, and then all you had to do was click import. Now I don't even see an import button, or anything else like it. So im lost... I don't know if it's something im doing wrong, or if our home sharing system just isn't working properly.
Thanks for the help.

How to use the same POWL query for multiple users

Hello,
I have defined a POWL query which executes properly. But if I map the same POWL query to 2 portal users and the 2 portal users try to access the same page simultaneously then it gives an error message to one of the users that
"Query 'ABC' is already open in another session."
where 'ABC' is the query name.
Can you please tell me how to use the same POWL query for multiple users ?
A fast reply would be highly appreciated.
Thanks and Regards,

Batch processing usually involves using actions you have recorded. In Action you can insert Path that can be used during processing documents. Path have some size so you may want to only process document that have the same size. Look in the Actions Palette fly-out menu for insert path. It inserts|records the current document work path into the action being worked on and when the action is played it inserts the path into the document as the current work path..

How to use airport time capsule with multiple computers?

I'm sure there are some thread about this but i couldn't find it... so sorry for that but hear me out! =)
I bought the AirPort Time Capsule to back up my MBP
And so i did.
then i thought "let give this one a fresh start" so i erased all of it with the disk utility and re-installed the MBP from the recovery disk.
I dont want all of the stuff i backed up just a few files and some pictures so i brought that back.. so far so good.
Now i want to do a new back up of my MBP so i open time machine settings, pick the drive on the time capsule and then "Choose" i wait for the beck up to begin, and then it fails. It says (sorry for my bad english, im swedish haha) "the mount /Volume/Data-1/StiflersMBP.sparsebundle is already in use for back up.
this is what i want:
i want the "StiflersMBP.sparsebundle" to just be so i can get some stuf when i need them. it's never to be erased.
i want to make a new back up of my MBP as if it's a second computer...
so guys and girls, what is the easiest and best solution?
Best regards!

TM does not work like that.
If you want files to use later.. do not use TM.
Or do not use TM to the same location. Plug a USB drive into the computer and use that as the target for the permanent backup.
Read some details of how TM works so you understand what it will do.

** How to use TO_DATE function in Stored Proc. for JDBC in ABAP-XSL mapping

Hi friends,
I use ABAP-XSL mapping to insert records in Oracle table. My Sender is File and receiver is JDBC. We use Oracle 10g database. All fields in table are VARCHAR2 except one field; this is having type 'DATE'.
I use Stored procedure to update the records in table. I have converted my string into date using the Oracle TO_DATE function. But, when I use this format, it throws an error in the Receiver CC. (But, the message is processed successfully in SXMB_MONI).
The input format I formed like below:
<X_EMP_START_DT hasQuot="No" isInput="1" type="DATE">
Value in Payload is like below.
<X_EMP_START_DT hasQuot="No" isInput="1" type="DATE">TO_DATE('18-11-1991','DD-MM-YYYY')</X_EMP_START_DT>
Error in CC comes as below:
Error processing request in sax parser: Error when executing statement for table/stored proc. 'SP_EMP_DETAILS' (structure 'STATEMENT'): java.lang.NumberFormatException: For input string: "TO_DATE('18"
Friends, I have tried, but unable to find the correct solution to insert.
Kindly help me to solve this issue.
Kind Regards,
Jegathees P.
(But, the same is working fine if we use direct method in ABAP-XSL ie. not thru Stored Procedure)

Hi Sinha,
Thanks for your reply.
I used the syntax
<xsl:call-template name="date:format-date">
<xsl:with-param name="date-time" select="string" />
<xsl:with-param name="pattern" select="string" />
</xsl:call-template>
in my Abap XSL. But, its not working correctly. The problem is 'href' function to import "date.xsl" in my XSLT is not able to do that. The system throws an error. Moreover, it is not able to write the command 'extension-element-prefixes' in my <xsl:stylesheet namespace>
May be I am not able to understand how to use this.
Anyway, I solved this problem by handling date conversion inside Oracle Stored Procedure. Now, its working fine.
Thank you.
