Strategic consideration of using Pro*C package vs. imbedded SQL Select

Hi,
I have a old application I'm looking into that uses proC call to get needed data thru Oracle Package.Procedure. Actual call to Package see below, 1 parameter, output in REF Cursor, SQL Select is simple nothing fancy.
I just wondering what could be advantages (if any) of doing this instead of coding actual SQL Select in my proC code ?
In case of any change you need to change proC and Package Body, rather then just do it in single place if used directly?
Source Control, PM, nice stucture inside Oracle , just corporate approach ???? Can anybody list at least one?
Appreciate your opinion, THanks to all.

Hi,
This isn't so much a direct response to your question, but this AskTom thread discusses some of the advantages to using code in the database vs. the client.
http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:30732069210515
If you search around you can find several other discussions of the same.
Centralization and reusability are two factors that lead me to favor code stored in the database.
Regards,
Mark

ORA-01458 error while using Pro*C to invoke PL/SQL procedure, pls help

I think the problem should happen between the mapping from internal datatype to external VARRAW type, but cannot understand why 4000 bytes buffer will be ok, is it related to some NLS_LANG settings, anyone can help me to resolve this problme, thanks a lot!

It seems that I found the way to avoid this error. Now each time before I read RAW(2000) data from database, i initialize the VARRAW.len first, set its value to SIZE_DATA_SEG, i.e., the outside buffer size, then the error disappear.
Oracle seems to need this information to handle its data mapping, but why output variable also needs this initialization, cannot precompiler get this from the definition of VARRAW structure?
Anyone have some suggestion?

Pros and cons of using email sending package in oracle 8.1.6

hi ,
i would like to know the advantages /disadvantages of using email sending package from oracle 8.1.6
compared to sending the same using say perl or php.
iam developing a site in php/oracle8.1.6 , in which iam supposed to create a payement module.whenever a user
register(for free trial or subscribing the site) i'll have to send him a welcoming mail.In addition to this iam also supposed to find out wether subscribers are paying cash at right time and if not send them reminder mails and other for related scenarios . i can do the same in Perl or PHP.but if iam not gaining much(say based on server performance or load) then i think i can go ahead with oracle package. when i tested it i found that its slow . what about the load that it may cause for the server (ours is linux ).
please do give inputs on this

Hi Ravi,
Thanks for your reply.

PDF created using Java iText package - Text not editable and not displaying font properties on Acrobat

Hi,
I have an issue in editing the text and viewing the font properties of a text region on a PDF created using Java iText package.
I use Adobe Acrobat 9 Pro Extended and the option Tools -> Advanced Editing -> TouchUp Text Tool.
The strange behaviour is that, I have 2 PDFs created out of the same base PDF and text added via Java iText package with the same Text, Font and other properties.
One of the PDF has the text region editable on Acrobat but the other one has the text region which is not editable.
But both the PDFs are editable via Adobe Illustrator.
I have attached both the PDFs for your reference
PDF_Editable.pdf - Editable on Acrobat
PDF_Not Editable.pdf - Not Editable on Acrobat
Any help or insight to find out the difference/issue with the PDF which is not editable via Acrobat would be appreciated.
Thanks in advance.
Regards,
Madhusoodhan Henryraman

You don't have direct control of the leading of a multiline text field. A common approach is to control the background color of the field with JavaScript since the lines are not really needed when the field is used in Reader/Acrobat. They may be useful when using the form by hand. For more information, see the posts by Max in this topic: http://acrobatusers.com/forum/forms-acrobat/how-do-i-use-multi-lined-text-fields-over-prin ted-line-area-existing-form

How to use two different packages which in different directories?

In my progrom, I'm using two differnet packages that in two different directories, but if I use classpath , the program can only be in one environment, so what can I do?

or you set your classpath to the first common dir they have, and specify the packages from that dir on...
or you just simply copy (you don't have to move it) the one package together with the other package...
by the way you can add multiple paths to your classpath...
between the paths you specify a ";"
if i'm not mistaken...

How do I make a batch file if the .class file uses a foreign package?

I am trying to make an MS-DOS batch file using the bytecode file from the Java source file, called AddFields.java. This program uses the package BreezySwing; which is not standard with the JDK. I had to download it seperately. I will come back to this batch file later.
But first, in order to prove the concept, I created a Java file called Soap.java in JCreator. It is a very simple GUI program that uses the javax.swing package; which does come with the JDK. The JDK is currently stored in the following directory: C:\Program Files\Java\jdk1.6.0_07. I have the PATH environment variable set to the 'bin' folder of the JDK. I believe that it is important that this variable stay this way because C:\Program Files\Java\jdk1.6.0_07\bin is where the file 'java.exe' and 'javac.exe' are stored. Here is my batch file so far for Soap:
@echo off
cd \acorn
set path=C:\Program Files\Java\jdk1.6.0_07\bin
set classpath=.
java Soap
pause
Before I ran this file, I compiled Soap.java in my IDE and then ran it successfully. Then I moved the .class file to the directory C:\acorn. I put NOTHING ELSE in this folder. then I told the computer where to find the file 'java.exe' which I know is needed for execution of the .class file. I put the above text in Notepad and then saved it as Soap.bat onto my desktop. When I double click on it, the command prompt comes up in a little green box for a few seconds, and then the GUI opens and says "It Works!". Now that I know the concept of batch files, I tried creating another one that used the BreezySwing package.
After I installed my JDK, I installed BreezySwing and TerminalIO which are two foreign packages that make building code much easier. I downloaded the .zip file from Lambert and Osborne called BreezySwingAndTerminalIO.zip. I extracted the files to the 'bin' folder of my JDK. Once I did this, and set the PATH environment variable to the 'bin' folder of my JDK, all BreezySwing and TerminalIO programs that I made worked. Now I wanted to make a batch file from the program AddFields.java. It is a GUI program that imports two packages, the traditional GUI javax.swing package and the foreign package BreezySwing. The user enters two numbers in two DoubleField objects and then selects one of four buttons; one for each arithmetic operation (add, subtract, multiply, or divide). Then the program displays the solution in a third DoubleField object. This program both compiles and runs successfully in JCreator. So, next I moved the .class file from the MyProjects folder that JCreator uses to C:\acorn. I put nothing else in this folder. The file Soap.class was still in there, but I did not think it would matter. Then I created the batch file:
@echo off
cd \acorn
set path=C:\Program Files\Java\jdk1.6.0_07\bin
set classpath=.
java AddFields
pause
As you can see, it is exactly the same as the one for Soap. I made this file in Notepad and called it AddFields.bat. Upon double clicking on the file, I got this error message from command prompt:
Exception in thread "main" java.lang.NoClassDefFoundError: BreezySwing/GBFrame

Press any key to continue . . .
I know that most of this makes no sense; but that it only means that it cannot find the class BreezySwing or GBFrame (which AddFields extends). Notice, however that it does not give an error for javax.swing. If I change the "set path..." command to anything other than the 'bin' folder of my JDK, I get this error:
'java' is not recognized as an internal or external command,
operable program or batch file.
Press any key to continue . . .
I know this means that the computer cannot find the file 'java.exe' which I believe holds all of the java.x.y.z style packages (native packages); but not BreezySwing or any other foreign packages. Remember, I do not get this error for any of the native Java packages. I decided to compare the java.x.y.z packages with BreezySwing:
I see that all of the native packages are not actually visible in the JDK's bin folder. I think that they are all stored in one of the .exe files in there because there are no .class files in the JDK's bin folder.
However, BreezySwing is different, there is no such file called "BreezySwing.exe"; there are just about 20 .class files all with names like "GBFrame.class", and "GBActionListener.class". As a last effort, I moved all of these .class files directly into the bin folder (they were originally in a seperate folder called BreezySwingAndTerminalIO). This did nothing; even with all of the files in the same folder as java.exe.
So my question is: What do I need to do to get the BreezySwing package recognized on my computer? Is there possibly a download for a file called "BreezySwing.exe" somewhere that would be similar to "java.exe" and contain all of the BreezySwing packages?

There is a lot of detail in your posts. I won't properly quote everything you put (too laborious). Instead I'll just put your words inside quotes (").
"..there are some things about the interface that I do not like."
Like +what?+ This is not a help desk, and I would appreciate you participating in this discussion by providing details of what it is about the 'interface' of webstart that you 'do not like'. They are probably misunderstandings on your part.
"Some of the .jar files I made were so dangerously corrupt, that I had to restart my computer before I could delete them."
Corrupt?! I have never once had the Java tools produce a corrupt Jar. OTOH, the 'cannot delete' problem might relate to the JRE gaining a file lock on the archive at run-time. If the file lock persisted after ending the app., it suggests that the JRE was not properly shut down. This is a bug in the code and should be fixed. Deploying as .class files will only 'hide' the problem (from casual inspection - though the Task Manager should show the orphaned 'java' process).
"I then turned to batch files for their simple structure and portability (I managed to successfully transport a java.util containing batch file from my computer to another). This was what I did:
- I created a folder called Task
- Then I copied three things into this folder: 1. The file "java.exe" from my JDK. 2. The program's .class file (Count.class). and 3. The original batch file.
- Then I moved the folder from a removable disk to the second computer's C drive (C:\Task).
- Last, I changed the code in the batch file...:"
That is the +funniest+ thing I've heard on the forums in the last 72 hours. You say that is easy?! Some points.
- editing batch files is not scalable to 100+ machines, let alone 10000+.
- The fact that Java worked on the target machine was because it was +already installed.+ Dragging the 'java.exe' onto a Windows PC which has no Java will not magically make it 'Java enabled'.
And speaking of Java on the client machine. Webstart has in-built mechanisms to ensure that the end user has the minimum required Java version to run the app. - we can also use the [deployJava.js|http://java.sun.com/javase/6/docs/technotes/guides/jweb/deployment_advice.html#deplToolkit] on the original web page, to check for minimum Java before it puts the link to download/install the app. - if the user does not have the required Java, the script should guide them through installing it.
Those nice features in deployJava.js are available to applets and apps. launched using webstart, but they are not available for (plain) Jar's or loose class files. So if 'ensuring the user has Java' is one of the requirements for your launch, you are barking up the wrong tree by deploying loose class files.
Note also that if you abandon webstart, but have your app. set up to work from a Jar, the installation process would be similar to above (though it would not need a .bat file, or editing it). This basic strategy is one way that I provide [Appleteer (as a downloadable ZIP archive)|http://pscode.org/appleteer/#download]. Though I side-step your part 1 by putting the stuff into a Jar with the path Appleteer/ - when the user expands the ZIP, the parts of the app. are already in the Appleteer directory.
Appleteer is also provided as a webstart launched application (and as an applet). Either of those are 'easier' to use than the downloadable ZIP, but I thought I would provide it in case the end user wants to save it to disk and transport the app. to a machine with no internet connection, but with Java (why they would be testing applets on a PC with no internet connection, I am not sure - but the option is there).
"I know that .jar and .exe files are out because I always get errors and I do not like their interfaces. "
What on earth are you talking about? Once the app. is on-screen, the end user would not be able to distinguish between
1) A Jar launched using a manifest.
2) A Jar launched using webstart.
3) Loose class files.
Your fixation on .bat files sounds much like the adage that 'If the only tool you have is a hammer, every job starts to look like a nail'.
Get over them, will you? +Using .bat files is not a practical way to provide a Java app. to the end user+ (and launching an app. from a .bat looks quite crappy and 'second hand' to +this+ user).
Edit 1:
The instructions for running Appleteer as a Jar are further up the page, in the [Running Appleteer: Application|http://pscode.org/appleteer/#application] section.

[java] java.rmi.ServerException: Missing port information
[java] at com.sun.xml.rpc.client.StreamingSender._raiseFault(StreamingSender.java:357)
[java] at com.sun.xml.rpc.client.StreamingSender._send(StreamingSender.java:228)
[java] at supercomputer.SuperIF_Stub.sendParam(SuperIF_Stub.java:60)
[java] at supercomputer.SuperClient.main(Unknown Source)
I dont know if it deploys why it gives error on client side.
Please tell how to use user-defined packages and class in jax-rpc service code ,i am not talking about passing user-defined parameters i am just talking about making objects of user defined classes in jax-rpc service.I think there is some problem in classpath.
Please guide me in doing that.
Thanks,
Farrukh

Farrukh,
I don't know if your error is about a missing class from your custom package, ... what track did you followed to say that?
To use your package in the implementation of you web service, you should only follow the rules of making a web application: put your package jar in your \lib directory inside WEB-INF/ or your package classes unjared in classes (also in WEB-INF/).
As I already said, I have doubts that your error should be originated from a missing class from your package, but:
-try to see the logs (errors?) when you deploy your web service that could give a hint about the problem.
-try to see if you can access your endpoint through your browser to see if there is a online status
-display your config/WSDL file, and the steps you did to build your web service.
regards,
Pedro Salazar.

Using Pro*C on Linux Oracle 8.1.6.0 on RH 6.2

Whe have some problems using Pro*C:
the program runs ok on all Oracle versions, including Oracle 8.1.6.0 on DEC OSF, but various sql errors are encountered on Linux Red Hat 6.2:
1) "ORA-01458: invalid length inside variable character string" for this code:
EXEC SQL BEGIN DECLARE SECTION;
varchar I_LANGLB [4];
short O_NOLBLB ;
varchar O_LIBELB [26];
EXEC SQL END DECLARE SECTION;
EXEC SQL INCLUDE SQLCA.H;
EXEC SQL WHENEVER SQLERROR GO TO MAJ_RESULT;
EXEC SQL WHENEVER NOT FOUND CONTINUE;
EXEC SQL DECLARE C0 CURSOR FOR
SELECT LBL.NOLBLB, LBL.LIBELB
FROM LBL
WHERE LBL.EDITLB = 'MON' AND LBL.LANGLB = :I_LANGLB;

I_LANGLB.len = 3;
EXEC SQL OPEN C0;
for ( ; ; )
EXEC SQL WHENEVER NOT FOUND DO break;
EXEC SQL FETCH C0 INTO :O_NOLBLB, :O_LIBELB;

2) with Dynamic Sql: "ORA-01007: variable not in select list"

WHERE MODEME = MODEML
AND nvl(INLBME,'1')='1'
ORDER BY MODEME,NOANML
[ or
ORDER BY 1,17 ]
In both cases,
We use the following precompiling options:
include=/oracle/OraHome1/precomp/lib ireclen=132 oreclen=132 sqlcheck=syntax parse=partial select_error=no char_map=VARCHAR2 mode=ORACLE unsafe_null=yes
dbms=V8
Could someone help ?
Thanks ...

My answer is only for 1. problem (about ORA-01458)
I think that you use declaration for cursor C0 with a varchar
variable before you ininitialize length (member .len of varchar
structure) of this variable.
It's famous that many errors come from uninitialized varchar
variables in Pro*C.

Error when using javax.script package

Hi
I want to call a javascript method from a .js file from .java class.
when i searched, i came to understand that using jdk1.6 i can use javax.script package tht provide me what i needed.
using the reply i got from i earlier post, i tried one example.
public void show() {
ScriptEngineManager engineMgr = new ScriptEngineManager();
ScriptEngine engine= engineMgr.getEngineByName("JavaScript");
try {
engine.eval(new FileReader("D:/ShowScript.js"));
Invocable invocableEngine = (Invocable) engine;
//show_message is my function in ShowScript.js file
invocableEngine.invokeFunction("show_message",null);
} catch (Exception e) {
e.printStackTrace();
ShowScript.js
function show_message()
println("===> hi");
alert("hi");
When i execute my program, im getting the following error
javax.script.ScriptException: sun.org.mozilla.javascript.internal.EcmaError: ReferenceError: "alert" is not defined. ( #8) in at line number 8
at com.sun.script.javascript.RhinoScriptEngine.invoke(RhinoScriptEngine.java:184)

When i remove the alert() from the js file, the println is working. But what i neede is the alert.
Can anyone plz help me to solve this problem.

As you're talking about "backing beans", are you using JSF?
After all, this is definitely not the way to let Java and JS interact with each other. Java runs at the server side. JS runs at the client side. Java can write JS code to the response, but definitely cannot call it. JS can access the HTML DOM and invoke requests to the server (form.submit() and AJAX and so on) and send parameters along the request, but definitely cannot call Java classes and methods independently. Nothing more and nothing less than that.

Using package constant in SQL

I am trying to use a package constant in a query as follows:
SELECT field1 FROM table t WHERE CEIL(sysdate - t.field2) > schema.package.constant
field1 is a name
field2 is a timestamp
constant is an integer indicating the expiration time in days
basically I am trying to find all expired items.
I get the error "ORA-06553: PLS-221: 'constant' is not a procedure or is undefined" on this query.
I use this same query as a cursor in the package itself with no errors.

Unfortunately you cannot directly use package global variables in select statements like this.
One workaround is to use bind variables for that:
<p>
SQL> CREATE OR REPLACE PACKAGE pkg
AS
   myconstant   VARCHAR (20) := 'This is my constant';
END pkg;
Package created.
SQL> VAR myconstant VARCHAR2 (20)
SQL> EXEC :myconstant := pkg.myconstant
PL/SQL procedure successfully completed.
SQL> SELECT :myconstant
FROM DUAL
:MYCONSTANT
This is my constant

How to make use of 32bit packages on Arch64

Hello everyone, I recently installed arch 64bit which was not yet fully tweaked to suit my needs.
My 32bit version has some nice apps and I would like to know how to make use of them or even reuse them so that I won't download things anymore because I have a slow internet connection...:)
Arch x86_64 / XFCE4
Thanks in advance

You can reuse the packages in /var/cache/pacman/pkg/ on your Arch32.
You can use these saved packages in a 32bit chroot ENV on your Arch64. Just pacman -U all of them.

How can I use Pro Tools with Fire Wire interface and Fire Wire external HD

If Mac Book Pro has only one Fire Wire jack and I want to use Pro Tools with an M Audio 1814 Firewire interface and an external Fire Wire HD how do I get around the fact that the Mac Book Pro has only one fire wire jack?
Pro Tools says that they DO NOT recommend using USB 2 Hard Drives as recording drives.
If I plug my External HD into the back of the 1814 it is way too slow to use, plus, I don't know why, Pro Tools is telling me that my External HD is "not a valid audio volume". It is a MAC OS Extended (Journaled) external Firewire HD (G-TECH G-DRIVE)
Stuck...

You could consider getting a firewire hub or get an expresscard 34 adapter with a firewire port.
I personally use a Belkin Expresscard adapter that gives me an extra firewire port as well as two extra USB 2.0 ports.
Good luck.

How can we use the same package in our report used by some other report

how can we use the same package in our report used by some other report

Hi,
You just need to assign package while saving your report.
No extra is required providing you are aware of package to be used.
