PLEASE HELP!!! Problem with Java and SQLServer Text data type

Hi there,
I have a java app. that reads from an MS SQLServer database. Originally, all long text fields were declared as NVARCHAR(200). The program worked fine.
Someone then advised that I change all long text fields to the TEXT data type. The program now crashes out with the following Exception:
"java.sql.SQLException: [JRun][SQLServer JDBC Driver]This ResultSet can not re-read row data for column 25."
Basically, I have a method that retrieves a resulset and iterates through it. The resultset is passed to another method during each iteration. In the example below, the 'specialNote' field used to be NVARCHAR(200). The code worked fine. Then when it was changed to TEXT, the program no longer works with the above Exception thrown.
Anyone know any special way SQLServer TEXT data types need to be handled?
Thanks for any advice!
The code looks something like this in functionality:
<CODE>
public void method1 (Connection conn)
Resultset rs = conn.createStatement().executeQuery("SELECT * FROM ProductBB");
while (rs.next())
method2(rs);
public void method2 (ResultSet rs)
String str = rs.getString("specialNote");
</CODE>

Hi JWoods,
Thanks for the suggestion. I originally had the code do what you suggested, ie, get the resultset then retrieve the data all within the same method. The data is then used to set properties in an object.
When I had to create another method that also retrieved a resultset but using a different primary key, then also use the returned data to set the properties in the same type of object, I didn't want to repeat the setter code. That's why I decided to pass the resultsets to the same method that did the property setting.
Unfortunately, it stopped working with the data type change.
Any other thoughts?

Xml, xsl, java and database

I have several xml documents that uses different tags to describe the same type of information. In my case they describe a row in a database table.
file1.xml
<therow>
<name>Jones</name>
<title>manager</title>
</therow>
file2.xml
<arow>
<employee>King</employee>
<job>manager</job>
</arow>
I want to use a technology for reading the content of the two files and generate a new document for each file that will use generic tags so the content of the new files could look like:
file1
<row>
<employeename>Jones</employeename>
<employeetitle>manager</employeetitle>
</row>
file2
<row>
<employeename>King</employeename>
<emplyeetitle>manager</employeetitle>
</row>
An then I can read this information by using a generic Java class and insert it into the database table..
I was told that the technology used for doing this was XSLT. I have been searching the web for examples and also tried to read some of the content in the Steve Muench book 'Building Oracle XML Applications'.
I have managed to create XSL files, but I would really appreciate if someone could show me a real example of how to do this, with the xml file, the xsl file, and a small java program to read this. Can anyone help?

Post your XSL files, otherwise we'd have to write them again.

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.

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.

The performance of management system with Java and MySQL

Hi all,
I want to develop one management application with Java and MySQL. However I am not sure which is a good way to design the system. The system has to deal with customers' data in the database.
Should I create objects for every customers when application starts so that I do not need to access to the database often? Or
Should I access to the database everytime the user want to deal with customer's data?
Welcome for any suggestion.
Thank you

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.

Getting started with Java and XML

Hi,
Although I am pretty familiar with Java, I am a total newbie with using it to parse XML. I have been reading quite a few tutorials so am getting a good understanding of it and am thinking of using the DOM model for my purposes.
What I haven't been able to find, however, is how I can actually get started with this. I have tried compiling a few examples and have been getting errors such as:
xmltest.java package javax.xml.parsers does not exist
xmltest.java package org.w3c.dom does not existetc etc...
It looks like these packages don't come with J2SE. Can anyone confirm this? Do I need to download and install the Java Web Services Developer Pack to solve this problem?
Finally, I know I will need an XML parser but have read that JDK 1.4 has it's own parser (Crimson). Is this adequate for parsing XML files or will I also need a parser such as Xerces?
Thanks so much for any help!

Hi DrClap,
Thanks for the reply. I have JDK 1.4.1_02 installed on my server but the following error keeps coming up when I try to run my example:
Exception in thread "main" java.lang.NoClassDefFoundError: org/w3c/dom/NodeAre there any further packages I need to download in order to run Java with XML? I have read some people install JAXP and XERCES... are these necessary for parsing an XML document or should J2SE 1.4.1 be sufficient?
Thanks for your help!

WDS Set up - Help Needed! Airport Extreme with one Relay and one remote

Hi Guys,
I need a bit of help. I am feeling quite stupid and frustrated. I am having some difficulty with setting up a WDS network with:
Base station: Airport extreme (current version)
Relay: Airport Express (current version)
Remote: Airport Express (current version)
I start by cold resetting the three units. The Base station is connected via Ethernet. The setup I wish to get going is a simple base - relay - remote.
I go through the utility manager and set up the base station, first as "create a wireless network" enter the ISP details etc etc. Its green light. Everything is fine. Then manually configure the Base Station. Hold down option key hit Participate in a WDS. I then select main enter + and add the Mac Id's for the intended Relay unit and Remote Unit (12 character and numeric string). At this stage I am only adding the intended Relay unit and Remote units MAC number.
Question 1: Do I need to add the base unit's MAC number itself under: WDS Remotes? even I am setting it up as Main?
I am careful to note the security settings and the the Wireless Network name to match these in the relay and remote set up. Under the Wireless tab I leave the Radio Mode: as Automatic (802.11a/n - 802.11b/g/n). I make sure the base has "allow this network to be extended" ticked. Under Radio Channel selection I edit it to reference channel 1 for 2.4Ghz (5 Ghz leave as Auto). I am careful when setting up the Relay and remote to match the Radio Channel. (Although I tired many channels as I thought maybe interference was a factor and denying the fact its obviously my set up skills as a factor).
Question 2: Do you need to disable Guest networks? I would think it does not matter as I have tired turning it off and has not made any difference.
Under Access Control I leave as default, Not enabled.
Next I hit update and and error message comes up. WDS Error as it can not find other units. Ok fine as the relay and remote are not yet set up. So I ignore and can get to the stage where the base unit is working and green light with an internet connection.
I then proceed to set up the Relay unit. Doing the same steps as above with a couple of differences being I add the MAC numbers and select the WDS Mode (Relay for Relay and Remote for Remote. I add the Main base station (i.e Airpot Extreme MAC No.) when prompted and then + the Remotes MAC number. The same for the Remote except I only need to add the base station's main no.
Question 3. Do I need to add the Relay's own MAC number to its own setup? This seems doubtful as with the base station but tired with and without for good measure with no success.
The 2.4Ghz channels are all set to 1. Radio mode set to Auto. Although even when I try to manually set them to all identical it doesn't seem t help.
Then the problems begin. The base unit is Green and the Relay and Remote say they are not connected to the internet. I assume since I have not seen a WDS Error message then the units are set up correctly or as I ignored it on the base unit. But when click unignore the error seems to work itself out.
Question 4. I need help to understand why I have no internet. The remote / relay says something about no IP number and I don't really understand what I should do? Do I need to go back the Airport Utility Manager and start messing about with the TCP/IP, DHCP, NAT ? The base is set up PPPoE and the relay and remote are set to Bridge.
It is really puzzling me why the relay and remote flash amber with error messages related to the IP number? I have tried turning off the base station and router and then on again but no joy.
Can anyone please enlighten me or give me a few ideas? I am doing something very obviously stupid and I guess the fix is something simple that I have overlooked.
I did spend the time and go through the threads and search online, So I am not trying to waste anyone's time I referenced the two links to get a second opinion:
http://broadcast.oreilly.com/2009/03/taming-an-airport-express-wds.html
http://www.macobserver.com/tmo/article/settingup_an_airport_relay_with_airportexpress/
Any help much appreciated!

Welcome to Apple's discussion groups.
My WDS experience is limited to "main" and "remote" configurations (no "relay"), so I'm not posting from direct experience, but below is what I think would work in your case.
I go through the utility manager and set up the base station, first as "create a wireless network" enter the ISP details etc etc. Its green light. Everything is fine. Then manually configure the Base Station. Hold down option key hit Participate in a WDS. I then select main enter + and add the Mac Id's for the intended Relay unit and Remote Unit
I don't think the "main" unit needs to be told about the "remote" unit, only about the "relay" unit.
Question 1: Do I need to add the base unit's MAC number itself under: WDS Remotes? even I am setting it up as Main?
You'd never enter the MAC address of a unit into its own configuration, if that's what you mean. I also don't think that you'd need to enter the MAC address of the main into the remote and conversely.
I am careful to note the security settings and the the Wireless Network name to match these in the relay and remote set up. Under the Wireless tab I leave the Radio Mode: as Automatic (802.11a/n - 802.11b/g/n).
Five things have to match in a WDS configuration: network name, encryption type, network password, band, and channel.
I make sure the base has "allow this network to be extended" ticked.
I don't think that's important for a WDS configuration.
Question 2: Do you need to disable Guest networks?
I wouldn't think that matters.
Under Access Control I leave as default, Not enabled.
That's fine.
WDS Error as it can not find other units. Ok fine as the relay and remote are not yet set up.
Right.
I then proceed to set up the Relay unit. Doing the same steps as above with a couple of differences being I add the MAC numbers and select the WDS Mode (Relay for Relay and Remote for Remote. I add the Main base station (i.e Airport Extreme MAC No.) when prompted and then + the Remotes MAC number. The same for the Remote except I only need to add the base station's main no.
I think this should be the MAC address of the relay station, not that of the main station.
Question 3. Do I need to add the Relay's own MAC number to its own setup?
No.
