XSQL Paging Example Questions - XMLBOOK

Hi all,
I run example NewsCategorySimple.xsql?p=2&id=1 from XMLBOOK (S.Muench pag. 650), but it doesn't show stateless paging. shows data, but not: Page 1 of 4 Next - Total 19.
I run over WNT4/Sp5, Ora816/R2, WEBDB/IAS, XSQL Utility (Examples is good), I don't have jdev 3.1 (is necesary?), my evironment variable CLASSPATH is add c:\xmlbook\samples\ch17\classes;....
Examples http://localhost/orxmlapp/samples/ch17/store.html is good
I think what configure Jserv (jserv.conf or jserv.properties) is the problem. can anybody help me
Thanks..

thanks, Steve
now is ok, but i have an other problem, in the URL: http://ias/orxmlapp/Examples/ch17/
I see the main page (index.html) and the message:
"No stocks selected" and "You have not selected any news categories... Preferences for roy-ayala". (XMLBOOK pag. 684, Fig. 17-23)
I added: wrapper.classpath=C:\xmlbook\samples\ch17\classes
wrapper.classpath=C:\xmlbook\samples\ch06\classes
in jserv.properties.
and run all script in ch06 / ch17
what do you think

XSQL SVG Example questions

The SVG example provided with the XSQL servlet is excellent and illustrates at least 5 different (and very useful) techniques. Congrats to whoever came up with it.
This one example shows SVG, named templates, use of xsl:variable, use of xsl_param, use of xsl:with-param, use of xsl:call-template and the apparent use of java classes from a jar file ala java server pages.
The example also raises several questions:
1. The example uses two namespace declarations I haven't seen before -
xmlns:Color="http://www.oracle.com/XSL/Transform/java/java.awt.Color"
and
xmlns:Integer="http://www.oracle.com/XSL/Transform/java/java.lang.Integer"
These appear to be allowing the use of Java classes in some jar file similar to the way Java server pages might do it.
It this correct? Is this because these two classes were built-in to the XSQL servlet? What other classes can be used? All of them? From any jar file? Is more documentation available?
2. What does the 'doctype=system="svg-19990812.dtd"' line do? There is no such DTD on my system but the demo works fine. There are references to DTDs with similar names in the FOP samples and in Adobe's samples but the name is slightly different.
3. Why is the media-type image/svg? The SVG 1.0 spec dated 2 Nov 2000 in section 1.2 says the SVG mime type is "image/svg+xml".
4. Why is there no namespace declaration for the svg tag or any of the svg related tags? Samples from other vendors seem to always have a declaration.
Thanks again for a great piece of code.

Rick,
You'll find a further-refined, and fully-explained version of the SVG example in Chapter 16 of Building Oracle XML Applications. This chapter covers the use of XSLT extension functions and illustrates how to use Java extension functions with the Oracle XSLT engine.
[list=1]
[*]The two namespaces you list are the way that the Oracle XSLT engine allows you to map extension functions in a namespace to methods of a Java class. This example illustrates using two different built-in classes of the JDK, java.awt.Color and java.lang.Integer. These are not specific to (or built-in in any way to the) XSQL processor or the XSLT engine, but are base classes in the JDK. You can use any Java extension functions in your XSLT stylesheets. The only requirement is that you (1) get the namespace correct to assign a namespace to the appropriate fully-qualified classname, and (2) make sure the classes you want to use are in the CLASSPATH.
[*]The <xsl:output> attribute doctype-system provides a value to be used for the SYSTEM URI of the <!DOCTYPE in the transformed output. The particular value was required by the SVG draft at the time I built the demo. It must be handled by a special entity-resolver built into the SVG Viewer that you're using, which explains why not having on your system as a physical file doesn't stop the demo from working.
[*]The media-type is image/svg instead of image/svg+xml because the SVG demo was built before the final draft of SVG went out. This value was apparently changed in one of the final drafts. It appears that the Adobe SVG viewer registers itself as the handler for both.
[*]See http://www.w3.org/TR/SVG/struct.html#NewDocument. The spec appears to allow both unqualified use of <svg> as well as namespace-qualified <svg:svg> when SVG is embedded within another document.

OCA example questions on Oracle website

May I ask those with more experience -- the sample OCA exam questions on the Oracle website (not any purchased practice test, just the 8 example questions) seem more devilish to me than any training materials or books I have read. The code is unformatted and unindented, deliberately tricky, static blocks popping up willy-nilly outside of methods and such, and for every question you just have to hack it out line by line. Whereas on practice tests I am scoring well, I got most of these samples wrong at first pass. There's not a single sample question there that's anything like the simple multiple choices I am getting in practice exams about basic concepts such as what is inheritance, what are interfaces, what is an abstract class, etc. etc. I guess my question is -- should I really be getting ready for 90 scary code-deciphering questions, even though my training materials reassure me I am doing just peachy? [I am keenly worried, by the way, about this question making it look like I don't like digging into troublesome code or that I am whining that it is "too hard."]
P.S. I am such a newbie I guess that I don't know basic things, but I am curious as to what the term "brain dump" means -- I have read on the forum that it is a form of cheating. I infer that it is basically training for exams by using quickie cheat-sheets instead of truly absorbing and knowing the material? Is that the definition? Why in heck would somebody want to get a certification that way if they couldn't actually do the work?
Best wishes to all.

Best wishes to all.I sometimes refer, somewhat cynically as is my way, to the 8 or so samples questions as the 'beta rejects' ... questions that were tried on the beta exam but rejected for the production exam. From my memory (perhaps a little poor) some are less than perfect.

DB Insert Example question

I want to insert data into a SQL database using the Insert Example.vi, as a base for my code. I have to add a large number of parameters to the database. My questions:
Is there a limit to the number of parammeters I can add?
I noticed that the example added two parameters (Device name and number of samples) It then uses "DB tools free object.vi" two times. Do I have to call the "DB tools....vi" once for every parameter I send?
thanks
Bob

There is no "limit" to the amount of fields that you can pass through an ODBC to SQL other than your connection timing out if it is EXTREMELYYYYY large.... I would guess that for all practical purposes you would not reach this point.
You can use the Insert Data vi which you would just have to specify the table name that you want to insert. Keep in mid that if you use this functiuon, you need to insert a cluster with THE SAME exact amount of fields as your table in the database. You would use this function if you want to insert a value to every single field in the database. If you dont, then you would use the Execute SQL Query vi, which you would wire a string with your query which in this case would be an INSERT statement.
I hope this helps.

Please ignore my previous posting. The reason for that error was that I did not register the ActionHandler in the appropriate config of the apache ...
As soon as I did it and reloaded the servlet, everything worked fine.

Old Producer/Consumer Example question

how would I take this code, the old producer/consumer example, and make it for 2 consumers and 1 producer?
basically, like this:
Producer put 1
Consumer #1 got 1
Consumer #2 got 1
Producer put 2
Consumer #1 got 2
Consumer #2 got 2
etc.....
***********Producer.java***************
public class Producer extends Thread {
private CubbyHole cubbyhole;
private int number;
public Producer(CubbyHole c, int number) {
cubbyhole = c;
this.number = number;
public void run() {
for (int i = 0; i < 10; i++) {
cubbyhole.put(i);
System.out.println("Producer #" + this.number
+ " put: " + i);
try {
sleep((int)(Math.random() * 100));
} catch (InterruptedException e) { }
***********Consumer.java***********
public class Consumer extends Thread {
private CubbyHole cubbyhole;
private int number;
public Consumer(CubbyHole c, int number) {
cubbyhole = c;
this.number = number;
public void run() {
int value = 0;
for (int i = 0; i < 10; i++) {
value = cubbyhole.get();
System.out.println("Consumer #" + this.number
+ " got: " + value);
***********CubbyHole.java***********
public class CubbyHole {
private int contents;
private boolean available = false;
public synchronized int get() {
while (available == false) {
try {
wait();
} catch (InterruptedException e) { }
available = false;
notifyAll();
return contents;
public synchronized void put(int value) {
while (available == true) {
try {
wait();
} catch (InterruptedException e) { }
contents = value;
available = true;
notifyAll();
***********ProducerConsumerTest.java***********
public class ProducerConsumerTest {
public static void main(String[] args) {
CubbyHole c = new CubbyHole();
Producer p1 = new Producer(c, 1);
Consumer c1 = new Consumer(c, 1);
p1.start();
c1.start();

instantiate another consumer.
public class ProducerConsumerTest {
public static void main(String[] args) {
CubbyHole c = new CubbyHole();
Producer p1 = new Producer(c, 1);
Consumer c1 = new Consumer(c, 1);
Consumer c2 = new Consumer(c, 2);
p1.start();
c1.start();
c2.start();
but then modify CubbyHole so that it checks that it has been consumed twice (as thats what you want, you said). Instead of using boolean available, use an integer flag that counts how many times its been consumed, and then reset the flag when it gets to 2. Something like that. Is this a college question? Do your homework. ha ha.

Java Proxies Inside Story Example: questions

Hi,
I've tried to implement the example of the document "Java Proxies and SAP XI - The Inside Story, Part II". Actually it's not running and I don't know why. Maybe anybody of you already implemented the described scenario successfully and can support me here:
InvokeProxy.jsp
- in the first code line, why is is import="http2Db.ProxyCall"? When I have a look at the coding, I think it should be import="http2Db.InvokeProxy"?
I've created the EAR project and deployed it to the J2EE Engine. When I try to test the scenario invoking the JSP side I just get back "The page cannot be displayed", the normal browser exception message. How can I check what goes wrong? Here I'm wondering that the Send Button of the HTML form in the JSP page invokes the function proxyfun(). That function itself has the following codeline within:
document.frm_proxy.action="ProxySender.jsp"
What's that for a jsp page? I cannot find it in the "Java Proxies[...].pdf"?
BR
Dennis

Has nobody tried this scenario before? Cannot imagine as it's always mentioned when there's a question concerning java proxy implementations as a reference
I mean the following documents:

Range Paging rownum question

I am using JDeveloper 11.1.1.3.0 and I have a question about the range paging access mode and I went through some docs but couldn't get myself to answer all the questions I have.
1. In the VO's I set the Access Mode to Range Paging and set the Range Size to 25 but I only have (at this time) 19 rows. But in the logs, I notice:
"<OracleSQLBuilderImpl><bindRangePagingParams> [2540] setting rownum query between (0, 28)"
which doesn't make sense. Firstly, 0-28 is not a 25 row range and secondly, why is the SQL even accessing anything outside the range of 25 when there are only 19 rows for the VO?
2. Also, I have two buttons on the page (page fragment #1) which performs operations (add a new row, version an existing row) by having the user go to a different page fragment (page fragment #2). After the user submits the info and returns to the original page (page fragment #1), I see this message in a pop-up:
"Cannot navigate with unposted rows in a RangePaging RowSet"
which, although not an error, doesn't make sense because the info was saved in the DB.
Hope my questions make sense.

I don't have the url reference handy for the "official" word, but I recall that jdev overfetches 3 records in range paging mode.
It's not known that there are only 19 records until the first batch is fetched, which is why you see 0-28.
Just noticed the second question - no comment on that one, unfortunately ;)

Bluetooth simple client example question

Dear all,
I am not sure whether I am close to make it. I update my bluetooth driver {http://forums.ni.com/ni/board/message?board.id=170&message.id=301780#M301780}, so it seem the labview (simple bluetooth server example) can work with my bluetooth (please read the first picture).

WL6.1 GA- IIOP examples question

Hi,
I have a couple of questions about the WL6.1GA - IIOP example. First when attempting
to build the example, the ant script halts with the following error:
compile_client:
Unable to create client.idl.
BUILD FAILED
E:\bea\wlserver6.1>>\samples\examples\iiop\ejb\stateless\cppclient\build.xml:41:null
On a closer look at the build.xml, the halt occurs with the WL defined ant class:"weblogic.ant.taskdefs.iiop.CppIdlSetup"
My first question, has anybody else been able to build the example as supplied
? Is there any massaging required ?
As I understand it, the previous step in the build (ejbc) generates the required
idl interfaces (Trader.idl, TradeResult.idl, TraderHome.idl) for accessing the
ejb.
So I'm very curious in seeing what the WL defined ant task is doing and defining
for ant generated idl (client.idl). Is the src for the WL defined ant task available
anywhere ?
Thanks in advance.
Wayne

Hi Andy,
The env. vars were set. Thanks for the
explanation, I was curious as to the latter :)

into a single file. Inprise have confirmed this as a defect and may
fix this for the next release of Visibroker at the end of the year.

Need help with problem using sound and vibration examples. question repost

I am generating a wav file using the sound and vibration example vi "SVXMPL_Wav Recorder(DAQmx)" using a ni 7422 board. Then, using the example vi SVXMPL_Getting started with SVT(Simulated)" attempting to play back that file. the wav file will load and play back on the graphs fine but when I click the "Play Wav File" which sends the audio to the computers speaker, I get the error "Cannot recognise sound Format". It plays the shipped example files fine. I can also play the wav files I generate on a Windows audio player. Don't know a lot about the sound and vibration toolkit or wav file formats but need to get these two to work together. Using LV 8.5 and sound and vibration toolkit 4.0. This is a bit of a repost of the same question ask last week but not answered. Thanks

Did you see Coq Rouge's reply in your original thread? Which thread are you going to continue?

Query by example questions

I have a couple questions. I have been using query by example and I really like it. What I want to do though I haven't seen, and i am new enough to toplink that i dont know the best way to do it.
Say I have a table t with 1 column (name : varchar2)
What I want to do is a query on name using the like operator (I know how to do this), what I dont know how to do is tell it to ignore case. So for example
select * from t where upper(name) like 'BU%'; something to this effect.
Any help greatly appreciated. If I cant do this with query by example which query method would you suggest?

If you use a QueryByExamplePolicy, you should be able to specify to use likeIgnoreCase for String.
i.e.
queryByExamplePolicy.addSpecialOperation(String.class, "likeIgnoreCase");
If you were using the Expression API this would be,
builder.get("name").toUpperCase().like("BU%");
or,
builder.get("name").likeIgnoreCase("BU%");

Scroll bar on clusters example - question

Hello,
I know there are allot of toppics about this subject but I found an example that would do the trick for me.
But it won't work. I can scroll but nothing happens...
I'll post the original example i found and an example to show you how i'm using it.
My cluster contains a boolean 2D array and a nummeric 1D array.
It is not the actual data but the setup is the same.

I think it could be a solution but it won't fill up.
I'll send you the original VI i'm working on.
You won't be able to run it though 'cause i'm using hardware.
I kept the original layout too so you could see what the idea actually was. But yours is an option too.

Spry Examples - Question

I'm not sure this is the case but it seems to me there are
many more examples referenced than on the "samples" page??
I would like to propose (if not already asked) that we have
an area that all the Spry examples + some good users examples
posted with a small description on one page or location. Others may
have other ideas as well... It just makes it easier than searching
through the slow forum here.... :o)
Thanks, Matt M

Example Question on InstanceProperty

I am building a plug-in, using the Oracle Enterprise Manager Extensibility Guide for examples to start from. I found this "snippet" in the guide:
<InstanceProperty NAME="Timeout" CREDENTIAL="FALSE" OPTIONAL="TRUE">
<Display>
<Label NLSID="netapp_filer_timeout">SNMP Timeout (Default: 5
seconds)</Label>
</Display>
5
</InstanceProperty>
When I validate the XML, the "5" comes up as an error, its not expected to be there. Is the extensibility guide incorrect in this spot?
I have something like it in my own very, very simple plug-in and I get a mysterious error in the console when I try to "Deploy" the new plug-in to the Agent (the error message is basically: Error, an Error occurred with a return type, please fix it and redeploy). Could this be the problem? I am just starting to use ILINT and it has its own set of mysteries ...
Paul

Are you using the PDK's lint tool or the agent's ILINT? I'd recommend the PDK's lint tool. It will more closely match the parsing which is done as a part of deployment. The agent's ILINT is a little more lax.
You may also want to try moving the 5 up a line:
<InstanceProperty NAME="...">
<Display>
<Label NLSID="...">...
</Label>
</Display>5
</InstanceProperty>
A subtle difference, but I've seen it done that way too.
Also, I think the CDATA tag should have extra [ ] brackets around the 5 in Shant's suggestion but it's getting parsed out for some reason.
