just fine from an Oracle database. but it chokes when trying
to update it. can anybody tell me what is happening?
thanks for any help

ResultSets based on a wildcard are generally treated as views by Oracle, meaning they are not updatable no matter how you create your statement. Try either "select swa.* from sw_assets swa" or "select all from sw_assets swa", that should get around the problem.
Also (just being thorough) make sure that you specifically created your statement as being updatable (stmt = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE) ).
I would not normally expect a NullPointerException when encountering this "feature", but then I don't often use the ODBC bridge.
Good luck! I hope this helps.

Problem with httpd and oracle database

hi
i have oracle linux with oracle database 11gR2
i install php with oci as the following link :
http://oss.oracle.com/projects/php/dist/documentation/installation.html
but when i try phpinfo() i found just only
*" /etc/php.d/oci8.ini"* in the result
and when i test connection i have this error
*" Fatal error: Call to undefined function oci_connect() "*
so what is the best way to install oci on oracle linux ?

What version of the OS are you using? Any clues in the syslog and httpd log? Are you using SELinux, which is often an overlooked issue?
Can you provide more details?

Discussion Forum Portlet - Problems with JAVA and UTF8?

Hi
I installed the Discussion Forum Portlet successfully. It also seems that almost everything works fine. There's only a problem if I have new posts that include special German characters (Umlaute) like ä, ö, ü or special French characters like é, è or ç. They are saved correctly in the table but if you view the post the characters are not displayed correctly.
Example
input: ça va?
result: Ã§a va?
I know that there are problems with Java and UTF8 Database. Is there a possibility to change this (bug)?
Regards
Mark

Oracle has released a Java 7 Update 11 to address security vulnerabilities and you should update to that version.

3 tiers model with Java and Oracle.

Hi everybody. I have a problem with my work. I want to design a simple program follow 3 tiers model with Java and database is Oracle. But I do not know how I can design them. Please help me. It will better if you give some source code for each layer.
Thanks in advance.
Ky Thanh.

I'd suggest searching the net for tutorials. Pick out the things you don't know about and need to know (SQL? JDBC? Java? software design in general?) and google: tier architecture, sql tutorial, etc. Sun's Java & JDBC tutorials are at http://java.sun.com/learning/tutorial/index.html
Source for each tier? Read the JDBC tutorial and you can write the database tier source yourself. Learn Swing/Servlets/whatever you use for the user interface and you can write the top tier. The middle tier is your business logic, which is dependent on your area of business, and you'll need to know about the business and just general programming. Then if the tiers need to be distributed (hopefully not), you'll need to learn EJB or something.
I hope you haven't been given a task there you aren't ready to take on... Learning to swim by jumping into the river is a great way to learn in a school assignment, but you mention work, and learning that way at work sounds a bit risky to me.

I have a problem with Java and an e-procurement system integrating

I use an e-procurement system at work and yesterday I could not get my parts list from the suppliers web site to display in our in-house eprocurment finance package.
There is not a problem with the finance package. There is not a problem with the suppliers web site. I have verified both of these by other colleagues being able to complete what I am trying to do.
The difference between my version of Firefox and my colleagues' is that I am on version 6.0.1 and they are on 6.0.
I have had problems with Java not displaying certain animations on the suppliers web site but, my colleague does not and I am suspicious that this is the problem. Can anyone verify this please and what can I do about it. My Java updates are up-to-date as of yesterday and are automatic.
Thanks.

I was quite amazed I never got a reply to this, in the past people here have been helpful. In any case I was finally able to enter this website on the exceptions list in the Java panel, and I believe it is okay now.

Events problem with (Java and ActiveX)

Hi,
I use an ActiveX component with Java and i've got a problem with events.
Java classes were generated with Bridge2Java (IBM).
In order to manage events I added a listener in my application :
javaMyActiveX = new MyActiveX();
javaMyActiveX.add_DMyActiveXEventsListener(new _DMyActiveXEventsAdapter());
I also added a constructor in the _DMyActiveXEventsAdapter class and I fill the body of methods.
The ActiveX generates two types of events :
- The ones are directly generated by methods.
- The others are generated by a thread.
With MS Products (VB, Visual C++, Visual J++), I catch all events.
With java (jdk 1.4), I catch only events generated by methods.
Can anyone help me.

I'm not 100% sure, but the last time I used that bridge, it only worked if you ran your Java app within a Microsoft VM.

Problem with Java and Windows (Mainly Vista and UAC)

Hi all,
I am having a problem with a program that I've devoloped. The program itself is packaged as a jar and I plan to deploy it across multiple platforms eventually however right now i am only concerned about windows based systems. I have made an installer for a windows baised systems using NSIS to install the software files. I made the installer as I need several java packages to be installed so the program would work (JAI, J3D, JAI ImageIO) and I also require the program to have fileassociations on windows.
I know that this is not what java is about, however the majority of the users will be on windows baised systems so I've decided that OS specific installers is the best option.
During the process I have noticed that there are several key problem with java for this type of application!
The first issue that I have come across is getting file associations to work on java. As a .jar is not an excutable it is not possible to directly associate a filetype with it in java so to overcome this I currently run the program from a .bat files and also the program requires large memory so this also allows me to run the program with -xmx. The batch file that I use is :
<code>
cd PATH TO PROGRAM
start javaw -Dsun.java2d.noddraw=true -Xmn100M -Xms500M -Xmx1000M -jar "PATH TO PROGRAM\program.jar" %1 -vram 134217728
pause;
</code>
Ok so all this appears to work fine and allows windows to have file associations and start the program and thats all works perfectly but this is a non-ideal solution. Has anyone got any advice on improving this?
The next problem that I have appears to be a problem with Vista and UAC (user access control). When a user installs the program and installs the program into the program files directory I found that the program did not work and kept saying that I did not have access to the files in the current directory. This is a problem as I read and write settings files during program execution.
On a Vista system UAC prevents file write operations into the Program Files directory unless the program has requested elevated status even if the user is a full administrator. The probem is that there appears to be no real way to achieve this under java that I'm aware of...
Has anyone else had this probem and has a suitable solution?
Any advice on these issues would realy be appricated.
Regards
Joey

Ok so i've kinda found a solution, its not ideal but its very good. I found this program called Elevate
A link to the site I got it was
http://www.wintellect.com/cs/blogs/jrobbins/archive/2007/03/27/elevate-a-process-at-the-command-line-in-vista.aspx
This program allows you start java with a UAC dialog for high access using
Elevate java -jar myjar.jar
This then allows you to have full access using java... I guess it could be dangerous but it does the job.

Problem with Unicode and Oracle NCLOB fields

When I try to INSERT a new (N)CLOB into an Oracle database, all is fine until I use a non-ASCII character, such as an accented roman letter, like the "�" (that's '\u00E9') in "caf�" or the Euro Currency symbol "?" (that's '\u20AC' as a Java character literal, just in case the display is corrupted here too). This doesn't happen with "setString", but does happen when streaming characters to the CLOB; however, as Oracle or the driver refuse strings larger than 4000 characters, and as I need to support all the above symbols (and many more), I'm stuck.
Here's the background to the problem (I've tried to be detailed, after a lot of looking around on the web, I've seen lots of people with similar problems, but no solutions: I've seen and been able to stream ASCII clobs, or add small NCHAR strings, but not stream NCLOBs...).
I'm using Oracle 9.2.0.1.0 with the "thin" JDBC driver, on a Windows box (XP Pro). My database instance is set up with AL32UTF8 as the database encoding, and UTF8 as the national character set.. I've created a simple user/schema, called LOBTEST, in which I created two tables (see below).
The basic problems are :
- with Oracle and JDBC, you can't set the value of a CLOB or NCLOB with PreparedStatement's setString or setCharacterStream methods (as it throws an exception when you send more than 4000 characters)
- with Oracle, you can only have one LONG VARCHAR-type field per table (according to their documentation) and you MUST read all columns in a set order (amongst other limitations).
- with a SQL INSERT command, there's no way to set the value of a parameter that's a CLOB (implementations of the CLOB interface can only be obtained by performing a SELECT.... but obviously, when I'm inserting, the record doesn't exist yet...). Workarounds include (possibly) JDBC 4 (doesn't exist yet...) or doing the following Oracle-specific stuff :
INSERT INTO MyTable (theID,theCLOB) VALUES (1, empty_clob());
SELECT * FROM MyTable WHERE theId = 1;
...and getting the empty CLOB back (via a ResultSet), and populating it. I have a very large application, that's deployed for many of our customers using SapDB and MySQL without a hitch, with "one-step" INSERTS; I can't feasibly change the application into "three-step INSERT-SELECT-UPDATE" just for Oracle, and I shouldn't need to!!!
The final workaround is to use Oracle-specific classes, described in:
http://download-east.oracle.com/otn_hosted_doc/jdeveloper/904preview/jdbc-javadoc/index.html
...such as CLOB (see my example). This works fine until I add some non-ASCII characters, at which point, irrespective of whether the CLOB data is 2 characters or 2 million characters, it throws the same exception:
java.io.IOException: Il n'y a plus de donn?es ? lire dans le socket
     at oracle.jdbc.dbaccess.DBError.SQLToIOException(DBError.java:716)
     at oracle.jdbc.driver.OracleClobWriter.flushBuffer(OracleClobWriter.java:270)
     at oracle.jdbc.driver.OracleClobWriter.flush(OracleClobWriter.java:204)
     at scratchpad.InsertOracleClobExample.main(InsertOracleClobExample.java:61)...where the error message in English is "No more data to read from socket". I need the Oracle-specific "setFormOfUse" method to force it to correctly use the encoding of the NCLOB field, without it, even plain ASCII data is rejected with an exception indicating that the character set is inappropriate. With a plain CLOB, I don't need it, but the plain CLOB refuses my non-ASCII data anyway.
So, many many thanks in advance for any advice. The remainder of my post includes my code example and a simple SQL script to create the table(s). You can mess around with the source code to test various combinations.
Thanks,
Chris B.

The solution to this is to use a third-party driver. Oranxo works really well.

Problems with java and SQL

Hi all. Not sure if I should ask this here or in an SQL forum. I�m trying to manipulate an access database through java via the JDBC-ODBC bridge driver. The program compiles ok but when I try to execute it I get an error. According to the error there is a syntax problem in my SQL create table statement but it doesn�t tell what the problem is and I�ve looked over the create statement and can�t find anything wrong with it. There is, however, an error code from the driver but I have no way of referencing it. Anyone here know why otherwise normal SQL code would cause a syntax error with java or how I can track the error to get a hint at what�s going wrong? Here is the code and the error:
// java program to create an access database through JDBC

Problems with Java and Business Objects

Hello everybody, I'm new in BusinessObjects/Crystal Report. Now, I have some problems with Business Objects for Java (Business Objects XI Release 2 Developer). 1) I create a report in the report designer. This report has a parameterfield. Before I run this report within a jsp web application I want fill the parameterfield with some values from the database. I found the following code snippet for this problem in your forum. But it don't works right, because it occurs a simple input field instead of a combo box with my database values. Where is my mistake? I need the combo box!

I got a message like this: 'At present in Java reporting Component does not implement'. I use JRC and the docs (http://support.businessobjects.com/global/interactive/xi/om/JRC/default.html) show me this method. Is it not possible to change the data at runtime in JRC?

Which Business Objects are you referring to.
MS .NET has a thing called Business Objects but they only work in .NET.

Reports from Java and Oracle database

Hi
I need to generate couple of reports from my application, with Java as front end and oracle 11.2.0.3.0. database . Reports are having very simple select statements, using the criteria users enter from GUI. we don't need to execute a direct select statement from Java, with the where clauses . I did some research and found out about Pipelined functions. I tested for a small set of records and it worked fine. Will this work for large data set? any drawbacks of using this method? Any other methods for this requirement?
Thanks in advance
JP

Pipeline table functions do not sound like the appropriate approach. It is designed to primarily deal with data transformations. Using it as a rendering engine for report writing? There are fundamental problems with such an approach.
As Dave and Andre commented - the CORRECT means for PL/SQL to pass "data" to Java (or other client languages) is via reference cursors (pointers that the client can use for referencing SQL cursor programs on the server). And Java as a report writer does not really compare with the ease and flexibility that Oracle Apex (Application Express) provides as a reporting framework.

Problem with java and yahoo games

hello everyone,
i have a mac 10.6.8 with java SE 6 1.6.0_33-603-424 and i have problems with yahoo games.... anyone can help me please, i have a mac 10.6.8 with java SE 6 1.6.0_33-603-424 and i have problems with yahoo games.... anyone can help me please

So here is what comes to pass.
Recall this started as a Lion Safari/5+ environment that SU took to version 6.
Two weeks ago I just updated Flash Player. Today I fire up Java Preferences and I am told that I need to download Java. Did so, intentionally hit the "factory reset" button and then installed the Flash Player from teh Adobe site. The most recent install suggests automatic update but I choose "ask first."
Restart Safari and we seem to be in order
Thanks

Problem with Java and Outlook

I am having a problem with the Java plug-in and Microsoft Outlook 2003. When I have Outlook running, going to certain websites (like cbs.sportsline.com/collegefootball) will crash my browser (IE). I get a message like this:
An unexpected exception has been detected in native code outside the VM.
Unexpected Signal : unknown exception code (0xe06d7363) occurred at PC=0x77E73887
Function=RaiseException+0x50
Library=C:\WINDOWS\system32\kernel32.dll
There is much more to the error message which appears as a text file on my desktop. If I close Outlook and try to go to that same CBS site, it works just fine. Has anyone else experienced this? Is there a solution?

In Window, the dlls are not private to one
application. They are logically shared. Not true in the sense that would affect this. DLL Text (code, read-only data in some cases) is shared. DLL Writable data is NOT shared between apps - each app gets its own copy of the data pages.
However, it's possible that when Outlook runs, it interacts with IE (which has deep tentacles into the system) in such a way that when Java calls into native IE code, it is affected as an innocent bystander.
Make sure you also install all the Office patches. If that doesn't help, try upgrading your Java VM to the latest version (you are using the Sun VM, right?).

If your database is using the AL32UTF8 character set, Forms 6i cannot connect.
