Using C++ code in java
is there any ways to use a C++ written file in a java file?
You are probably looking for JNI = Java Native Interface. Do a web search on that, there are tutorials on this site

Hi All,
The Actual query to perform is below.
SELECT name,number from emp WHERE CASE WHEN :1='T' AND term_date IS Not NULL THEN 1 WHEN :1='A' AND term_date IS NULL THEN 1 WHEN :1='ALL' THEN 1 ELSE 1 END = 1;
I have tried in DB adapter like below as a parameter for :1 as #vInputParam
SELECT name,number from emp WHERE CASE WHEN #vInputParam='T' AND term_date IS Not NULL THEN 1 WHEN #vInputParam='A' AND term_date IS NULL THEN 1 WHEN #vInputParam='ALL' THEN 1 ELSE 1 END = 1;
Getting Error code :17003 .java.sql.SQLException: Invalid column index error.
Please suggest me on using ':' bind character in DB adapter Select Query SOA11g.
Can someone help me on this please?
Thanks,
HariHi,
Could you please make sure your binding style(Oracle Positional,Oracle named..etc) of the Seeded VO and Custom Vo are same.
This is the option you will get when you are extending your vo. So make sure that both are same.
You can refer the below link too
VO extension leads to "Invalid column index" exception

Search information using a VO by java code..?
Search information using a VO by java code.
Hi to all
Im trying to retrieve specific information by java using the VO object that I have attaché to the EO. I need to know if this is possible and how to.
For example lest say that I have the following information user name and password and I wand the telephone and other information.
Can some pls help me with a link of an example of how to do this.
Tanks to all.Hi JulianeE
Yes it is possbile, please generate the VORowImpl file on the corresponding VO object. Even if your query return multple rows, it can . see the sample code below
OAViewObject vo1 = (OAViewObject)am.findViewObject("EmployeeEOVO1");
vo1.reset();
if (vo1 != null)
do
if(!vo1.hasNext())
break;
vo1.next();
EmployeeEOVORowImpl lcerl = (EmployeeEOVORowImpl)vo1.getCurrentRow();
lcerl.getFullName();
Thanks

How not to use Cold Fusion and Java
Overview
This write up is intended to give java developers that are
developing ColdFusion applications some beneficial information:
things that are not documented.
Scenario
The company builds enterprise class web application software
for fortune 500 companies. It had purchased a CF 7 based product,
had and existing proprietary J2EE based product, and needed to
integrate the two while meeting a host of new requirements. These
requirements were based on delivering a better user experience,
faster / cheaper integration, increased flexibility /
configuration, useablily, decreasing maintenance costs, the ability
to deploy in either install or ASP models. An initiative was
started to create a new framework that integrated the best of each
technologies. Tactically, this meant that we were to build a hybrid
CF and java application: one that used building blocks (decoupled /
cohesive components) that would allow applications to be rapidly
assembled, configured and deployed. This made sense on several
levels, the team was composed of Java and CF developers, the CF
rapid application development was very productive, there is great
functionality delivered in the CF platform and initial performance
tests showed no cause for alarm
The agreed upon design, based on requirements, and analysis
by both the CF and Java staff has us using CF in the presentation
layer, using a CF based MVC, use of CF based web services. The MVC
was deployed using CFC inheritance for model objects and views made
use of CF custom tags. The internals of the application, used a
rules engine, some proprietary java, ORM, and other J2EE
technology. The initial performance of the system was reasonable.
We pushed on with product implementation.
Then it was time to load test the application, and tune it.
Under load the response times were orders of magnitude slower,
sometimes the pages even timed out.
Armed with our profiler, oracle execution plans and we
charged ahead addressing issue after issue. Note that we took
meticulous care in tweaking the active thread pool and ensuring
that our CF setup was tuned for our application. None of the
observations here are a condemnation of the language; rather they
are aspects that, when considered together, not conducive for
building integrated java and CF frameworks that use a structured /
OO programming practices. Further detail can be provided on
request.
CFC inheritance should be avoided - resolution of variable
scope is expensive even if properly declared.
Since CF creates a class per method under the covers call
stacks become very large, especially if used in a loop. This is
nominally exacerbated by CF calls necessary to set up for the
method call (String.toUpper()).
Nesting of loops and if statements should be kept to a
minimum - the conditional for each lookup of logical operator like
LT, GT are synchronized. Under load this results in thread waits.
Jrun has as single thread pool - both http and web service
requests use the same pool. Under load this leads to thread
deadlock. There are work arounds, but they are painful.
Recursion should be avoided - we had a few recursive routines
and these had to be rewritten.
Custom Tags - should be used sparingly - each custom tag
makes a synchronized call to the license server - (This may be
fixed in CF 8)
Summary
In the end we got the performance to reasonable numbers, but
we ended up moving some code to java (Custom Tags) and getting rid
of 'good programming' practices (Inheritance, loops, etc), mandated
proper variable scoping for those things left over. We prototyped a
sans cold fusion implementation and had an order of magnitude
improvement in performance and number of requests served per
second.
The lesson? Use Coldfusion in its sweet spot: make a query,
iterate over the results and format for display. Extensive use of
structure programming techniques or OO CFCs should be avoided: they
will work but under load - but are better as a prototype. Building
frameworks in CF? Think twice, no three times, and, if you must, be
minimalist.
Textinteresting aslbert123,
Not that I doubt you, but could you answer some questions
about your implementation that was so slow:
1.) Did you put your CFCs in the application or server scope?
2.) Were you initializing your CFCs, via CreateObject or
<cfinvoke>, on every request?
3.) Are you sure that you were properly Var'ing every
variable in your methods? (people typically forget about query
names and loop iterator variables)
4.) Could you give examples of how your inheritence was set
up?
5.) For CustomTags, did you call them the old <cf_tag>
way or the newer, better-performing <cfimport> way?
6.) How did you connect CF to Java exactly?
Thanks,

Using XMLType in a Java Stored Procedure
I have the following piece of java test code that attempts to read an XMLType object from the database. When I run this client side, using either the oci or thin driver it works fine. When I run the same code as a java stored procedure I get the exception shown below.
(The problem was first seen on 9.2.0.3/Win2K. Ive patched to 9.2.0.4 and am still getting the same error)
Can anybody please help?

How to use Thread.sleep() with Java Berkeley Base API?
Hi,
I have explained the weird problem about the server was too busy to response to SSH but it continued to finish to run (Server not response when inserting millions of records using Java Base API
Even I tried to increase CachSize and renice Java program, but it did not work. So, I am thinking to set sleeping time for threads in Java Berkeley Base API (using “ps” command, there were 18 light weight processes created). My program did not implement transaction or concurrency because it simply creates (millions) databases records only. Is it possible and correct to do like this in the code:
try{
//do create a db record
Thread.currentThread().sleep(1000);//sleep for 1000 ms
catch(ItrerruptedException ie){
Thank you for your kindly suggestion.
Nattiyawhere can I get the help doc about use AT commands in java.
Can you give me some code example about this. It is
difficulty to me to write it myself.You simply have to send the characters and receive the characters via the comm extension. Here is the ITU standard command set - http://ridge.trideja.com/wireless/atcommands/v250.pdf. Various modems and other devices extend this in a number of ways, you may need to find documentation specific to your device as well. But start with the standard. -

Please help me transform this C++ code to java code....

[program]
#include <stdio.h>
#define ALIVE 1
#define DEAD 0
#define SZ 33
int stschk (int ,int );
main()
int s[SZ][SZ], i, j;
for (i=0; i<sz; i++ ) s[0] = DEAD;

printf("\n");
int stschk(int s1,int s2)
if(((s1==DEAD)&&(s2==ALIVE))||
((s1==ALIVE)&&(s2==DEAD))) return ALIVE;
else return DEAD;Being picky, that's not C++, that's C. Standard headers in C++ dont' have .h after them, loop variables are scoped with the for, you use constants rather than #defines, etc..
C and C++ both don't initialise arrays by default; you'd have to write an initialiser to get it to zero out the array:
int s[sz][sz] = {};gcc will insert a call to memset to zero the array.
If the author was assuming that the array was zeroed out, there would be no point zeroing the first row and column.
The code reads values which haven't been initialised. If you mark such values explicitly undefined, and change the program to report an error when undefined, then you get several cases where the program makes such report.
So either it' s a primitive random number generator (some random number generators use uninitialised memory as a source of randomness), or it's buggy, or it's processing undefined data and throwing away the result. Either way, it cannot be directly be ported to Java if the undefined values (which are limited to a small area of the ouput) are significant. -
Parsing an XML using DOM parser in Java in Recursive fashion
I need to parse an XML using DOM parser in Java. New tags can be added to the XML in future. Code should be written in such a way that even with new tags added there should not be any code change. I felt that parsing the XML recursively can solve this problem. Can any one please share sample Java code that parses XML recursively. Thanks in Advance.
Actually, if you are planning to use DOM then you will be doing that task after you parse the data. But anyway, have you read any tutorials or books about how to process XML in Java? If not, my suggestion would be to start by doing that. You cannot learn that by fishing on forums. Try this one for example:

How to use the build-in Java parser
Hi All,
I want do use the build-in Java parser. Is this possible? For example I have the following code:
package ch.fhnw;
import javax.tools.*;
public class JavacExample {
* @param args
public static void main(String[] args) {
JavaCompiler javac = ToolProvider.getSystemJavaCompiler();
String arguments = "./src/ch/fhnw/JavacExample.java";
int rc = javac.run(null , null, null, "-verbose", arguments);
System.out.println("Return value: " + rc);
}After parsing, it would be great to have an object or similar which contains the methods, arguments used by the methods, etc. The target is to extract method declarations from java files. Is there a simple way to do it without defining my own EBNF like in JavaCC? Or any other way?
Thank you for your help.
kind regards,

how to write a bean to get this xmloutput.
thank in advanceHi Sliba,
You may download and use the XDK for Java that is available from OTN to do this.
Here is the code that will be handy for use. Just substitute your XML document and stylesheet
in the code snippet pasted below. I hope this helps.
There are many more useful XML samples you can find at http://otn.oracle.com/sample_code/tech/xml/content.html
