BacNet using Java
BacNet Protocol Support
====================
My application uses Real-Time devices. Hence I prefer to use BacNet protocol for monitoring via Remote.
But I don't have any idea about Java's support about Bacnet.
Let me know if we have any support in Java.
You can very well send a mail to [email protected]

I am trying to use java file as Model layer and jsf as presentation layer and need some help
I successfully get the value of h:outputText from java file by doing simple binding operation but I am facing problems when I am trying to fill h:dataTable
I create java file

Using Java, How can I Update, Add, Delete nodes in XML Files.
Hi,
I want to store the student record (like Name, Age, school name, total mark etc.,) as nodes in the XMLfile. Also I should able to Update, Add, Delete any nodes (student record) in the XML file. How can I achieve this...using Java
I am able to read the content of the xml file using xml-parser. But my problem is
updating the xml file.
pls suggest some solutions or links with " example source code"
Thanks :-)There are 2 kinds of XML parsers : SAX and DOM. DOM seems to suit your need. You can use JAXP APIs to add, delete or change nodes or attributes.
http://java.sun.com/webservices/jaxp/dist/1.1/docs/tutorial/TOC.html provides contents that would satisfy most of the needs.
To save a DOM modified XML file use java IO APIs to write to the same file from which it was read using a Document object ( doc.getNodeValue() ). -
ORA-04030: out of process memory when using Java Stored Procedures
Hello,
I have a problem using Java Stored Procedures in Oracle 10g.
My Java application performs http posts to a webservice and the response is parsed in order to populate some DB tables.
There is a scheduled job which calls the Java Stored Procedure every x minutes.
No matter of the 'x minutes' values - after about 160 - 200 calls I get this error:
ORA-04030: out of process memory when trying to allocate 1048620 bytes (joxp heap,f:OldSpace)
ORA-04030: out of process memory when trying to allocate 2097196 bytes (joxp heap,f:OldSpace)
The job stops just while is posting the http request. The weird thing is that almost each time the first http post request I get this error:
java.net.ConnectException: Connection refused
at java.net.PlainSocketImpl.socketConnect(Native Method)

and the second try works fine.
So, The out of process memory occured each time just before getting such an error, and I suspect to be a connection between these errors.
Tech details:
1. OS: WinXP
2. Oracle 10.1.0.2.0
3. To perform http post I use HttpClient 3.1 from Apache.
4. I checked the http connection to be closed each time, and this is done.
5. I checked the oracle statement and connection to be closed each time and this is done
6. The JVM error (logged in .trc files of Oracle) is:

Can be a problem with JVM threading under Oracle ?The server prcess failed to allocate more memory for large objects ( in Oldspace).
If you Google ORA-04030, you will see several recommendations to work around this.
The Java VM in the database already has HttpClient, i don't know why you are loading the Apache HttpClient but this might not be the surce of the problem.

Using Java Access bridge (Accessibility) with oracle forms 6.0 client
I'm trying to use JAB (java Access bridge ) to capture events in oracle forms 6.0 client .
I've a Jinitiator 1.1.8 and JRE version 1.4x
I've configured JAB as per the installation guide . However the events don't surface in Java Monkey .
Has anybody encountered similar issue ? what is the solution for the issue ??
Also on one of the forums I read Jinitiator 1.3x and above is automatically recognised by Java Access bridge .
For jinitiator version less than 1.3 manual configuration is required . however I haven;'t been able to find any on the oracle forms KB
Also here is the excerpt from the link http://www.oracle.com/us/corporate/accessibility/faqs/index.html
Q: Are there special steps for using Java-based applications with assistive technology?
A: If the Oracle application is written in Java, such as JDeveloper or Oracle Forms (runtime), customers must first install the latest version of Sun's Java Access Bridge. The Java Access Bridge provides the integration with screen readers such as JAWS or SuperNova that support Java. You just download the Access Bridge and install it. Sun's AccessBridge 2.0x recognizes Oracle's JInitiator 1.3x and above so no manual configuration steps are necessary. The Access Bridge is available from: http://java.sun.com/products/accessbridge. At the time this document was written, Access Bridge 2.0.1 is the most current publicly available production release; Oracle recommends upgrading to this version. Sun's AccessBridge is bundled with Oracle Universal Installer (OUI) and can be found in the Java Runtime Engine (JRE). More information for configuring such products is in the respective product documentation, or on http://www.oracle.com/us/corporate/accessibility/products/index.html.
Edited by: 974810 on 4 Dec, 2012 1:10 AMODP.NET requires Oracle Client 9.2 or higher.
You can find additional information about ODP.NET from the FAQ:

Unable to run my application using java web start
i have created one application and use java web start to download the application. all the files are succesfully downloaded but when i try to run the application an expected error occur. this only happen in my machine but not in other machine i'm currently using
-jsdk1.4.2
-windows 2000 professional 5.00.2195 service pack 3
-pentium III 870 Mhz
-x86-based PC
-RAM 256 Mhz
Anyone knows why, plz help me with this puzzlePlease post the information from the Web Start "Exception" and "Wrapped Exception" tabs when the error occurs (I assume the error was in fact unexpected ;-)
A blind stab in the dark would be that you don't have write permission to the cache directory on the second machine. Also worth checking that the proxy settings on the second machine are the same as the first (if they are on the same network). -
How to get comparable Oracle JDBC performance using Java 1.4 vs 1.1.7?
Our application makes extensive use of JDBC to access an Oracle database. We wrote it a number of years ago using java 1.1.7 and we have been unable to move to new versions of java because of the performance degradation.
I traced the problem to JDBC calls. I can reproduce the problem using a simple program that simply connects to the database, executes a simple query and then reads the data. The same program running under java 1.4 is about 60% slower than under java 1.1.7. The query is about 80% slower and getting the data is about 150% slower!
The program is attached below. Note, I run the steps twice as the first time the times are much larger which I attribute to java doing some initializations. So the second set of values I think are more representative of the actual performance in our application where there are numerous accesses to the database. Specifically, I focus on step 4 which is the execute query command and step 5 which is the data retrieval step. The table being read has 4 columns with 170 tuples in it.
Here are the timings I get when I run this on a Sparc Ultra 5 running
SunOs 5.8 using an Oracle database running 8.1.7:
java 1.1.7 java 1.4
overall: 2.1s 3.5s
step 1: 30 200
step 2: 886 2009
step 3: 2 2
step 4: 9 17
step 5: 122 187
step 6: 1 1
step 1: 0 0
step 2: 203 161
step 3: 0 1
step 4: 8 15 <- 87% slower
step 5: 48 117 <- 143% slower
step 6: 1 2I find the same poor performance from java versions 1.2 and 1.3.
I tried using DataDirect's type 4 JDBC driver which gives a little better performance but overall it is still much slower than using java 1.1.7.
Why do the newer versions of java have such poor performance when using JDBC?
What can be done so that we can have performance similar to java 1.1.7
using java 1.4?

}If I run my sample program with the -server option, it
takes a lot longer (6.8s vs 3.5s).Which has to be expected, as the -server option optimizes for long running programs - so it shoudl go with my second suggestion, more below...
I am not certain what you mean by "just let the jvm
running". Our users issue a command (in Unix) which
invokes one of our java programs to access or update
data in a database. I think what you are suggesting
would require that I rewrite our application to have a
java program always running on the users workstation
and to also rewrite our
commands (over a hundred) to some how pass data and
receive data with this new server java program. That
does not seem a very reasonable just to move to a new
version of java. Or are you suggesting something
else?No I was just suggestion what you descript. But if this is not an option, then maybe you should merge your java-programs to C or another native language. Or you could try the IBM-JDK with the -faststart (or similar) option. If thew Unix you mention is AIX, then there would be the option of a resetable-vm. But I cannot say if this VM would solve your problem. Java is definitly not good for applications which only issue some unqiue commands because the hotspot-compiler can not be efficiently used there. You can only try to get 1.1.7 performance by experimenting with vm-parameters (execute java -X). -

How to get the values from struct data type using java code..?
Hi ,
I am newer to java.
we are using oracle database.
How to get the data from struct data type using java code.
Thanks in Advance.
Regards,
kumarHi Rajeev,
To retrieve a FilterContainer you will need to traverse the report structure:
ReportStructure boReportStructure = boDocumentInstance.getStructure();
ReportContainer boReportContainer = (ReportContainer) boReportStructure.getReportElement(0);
FilterContainer boFilterContainer = null;
if (boReportContainer.hasFilter()) {
boFilterContainer = boReportContainer.getFilter();
} else {
boFilterContainer = boReportContainer.createFilter(LogicalOperator.AND);
Calling boDocumentInstance.getStructure() will retrieve the entire structure for the document.
Calling boReportStructure.getReportElement(0) will retrieve the structure for the first report of the document.
Hope this helps.
