Using built in Java Icons

Hi,
I am using Swing and building my own Dialog box, because Java doesn't provide a dialog box that asks for username/password.
My Question: I like the icons Java uses for its dialog boxes (example here: http://java.sun.com/docs/books/tutorial/figures/uiswing/components/OptionDialogMetal.png )
How can I import this icon into my dialog box?

Please look at here
http://java.sun.com/docs/books/tutorial/uiswing/components/dialog.html
And you have use to correct Look and Feel

External SOAP client Accessing Webservice using built in Java Data type

We have built a webservice and deployed it on WLS. We accessed this from a swing
client it works fine.The webservice methods uses non-built in JAVA data types
as parameters.These are Value Objects and the JAVA Serializer and Deserializer
classes are generated using Ant task itself.The client coding uses Value objects
given by the Client_jar (generated using <Clientgen> ant task) to pass to the
webservice. We dont want to go by this way.Is there anyway were in we can pass
parameters to the method which expects non-built in java datatypes?
Why i am asking this is, i want to know how an external client (.Net client )
will be able to exceute my webservice (i.e., passing the required Object which
the method is expecting)?

Hi Anish,
Well first off, your web service doesn't send or receive "objects". It only sends
and recieves XML, which is in turn converted to/from Java objects at invocation
time. Second, a .NET (or Perl, or Python, or C++) client will be able to call
your web service, because the wsdl.exe tool (for .NET) will generate "programming
language specific" objects from the <types><schema> elements, in the WSDL of your
web service :-) The wsdl.exe tool will create C# objects from the WSDL, that will
convert XML to/from C# when your web service is called. That's the beauty of XML
schema - it's a "universal typing system", so it's not tied to a particular programming
language. The only issue is whether or not the web services platform vendor's
XML Schema/WSDL processor, can successfully process the WSDL. Some vendors have
more complete implementations of the WSDL and XML Schema specs than others, so
expect varying success here. The one in WLS 7.0 is pretty good, so you shouldn't
have too many problems consuming WSDL generated by .NET tools (or any other tool
for that matter).

How can i built a java application using java debug class on Log4J

Hi,
As java API support the MethodEntryEvent, using which I can get the automatic logging statements when the method is entered or exited as HelloExample.main(with argument type).
Where HelloExample is the class name.
Main is the method entered with its argument types.
In some cases I have the o/p as
-- VM Started --
====== main ======
main -- HelloExample
callerMethod -- HelloExample
====== main end ======
-- The application exited --
By using Log4J is there any possibility of getting these sort of o/p along with the loggers supported by Log4J. i mean to say can i built an java application which supports the MethodEntryEvent and MethodExitEvent from java API and also uses the Log4J debugging. I took an e.g. trace example, which (in J2SE 1.4.x or 5.x) will be found in $JAVA_HOME/demo/jpda/examples.jar and unpacking it by
jar -xvf $JAVA_HOME/demo/jpda/examples.jar i found the com/sun/tools/example/trace/Trace.java and passed the class constructed with logger taken from Log4J. In this case the logging message is displayed on the console. As per the requirement i need to transfer the whole o/p to an output file along with Log4J logger statements. in this case i should not give any command in the cosule except compiling and executing the programme. the programm also should able to run without the main() as i need to integrate Log4J with an application and the code must me application server independent. i need the output as i got using MethodEnteryEvent (shown as above) in case of java application built using Log4J.
Can any one help me in this regard. can any one give me some suggestion or any programme of this sort. All suggestions are welcomed.
Thanks & Regards,

hi,
can someone help me how to implement logging for method entry parameters and
method exit return value.
can someone help me how to use log4j and integrate it to the method entry
logging and method exit logging.
Here what i need is without writing the log statements for the method entry and
method exit i need to log it to the file
along with other log4j debug statements i provide in the file.I should be able
to configure whether to enable/disable the logging
for method entry and method exit. In method entry i should be able to log the
parameters the method take and in method exit
i should be able to log te return value to the log file, before the method is
returned to the callee.
i hope i am clear
Thanks in advance.

Using Java Icons in 3rd Party Software

Hi,
First apologies if this posted to the wrong forum but I could not find any others that were suitable.
I develop a business process modelling tool that allows the user to create models that can be activated and executed as live enterprise systems.
I wish to add the ability to call java classes/methods as part of the process. No problem there, but to represent the calling of Java I would like to use the standard Java "cup" icon within the graphical model that my software displays.
Does anyone know if this is permissable by Sun? If I use Sun logo's in my software am I breaking any copyright laws etc. ? Would I need a disclaimer saying that Sun does not endorse my product if I did use it?
I can't find any info on this in the readme's. I have found some re-usable toolbar icons supplied by Sun to keep a consistant look and feel but nothing more.
Any help or advice would be appreciated.
Cheers

Should I change it?

Neeraj -
The Portal framework code (including PortalAppflowHelper) uses ejb
references to find the PortalManager (and other EJBs) from servlets and
taglibs; that is what is signified by the java:comp/env/... name.
Since you built your webapp from scratch (instead of using the portal
wizard), you will need to make sure the you have the appropriate
<ejb-ref> entries in your web.xml, and the corresponding
<ejb-reference-description> entries in your weblogic.xml. By default,
you will need at least mappings for:
- ejb/PortalManager
- ejb/UserManager
- ejb/GroupManager
- ejb/PipelineExecutor
- ejb/EventService
See either the resulting webapp from using the portal wizard or
BEA_HOME/weblogic700/samples/portal/sampleportalDomain/beaApps/sampleportal/sampleportal/WEB-INF
for example syntax.

Reading/Writing .xlsx files using Webdynpro for Java

Dear All
I have a requirement to read/write excel files in .xlsx format. I am good in doing it with .xls format using jxl.jar. The jxl.jar doesn't support .xlsx format. Kindly help me in understanding how do I need to proceed on reading/writing .xlsx files using Webdynpro for Java.
Thanks and Regards

i am using jdk 1.6.22 and IBM WebSphere
when i use poi-3.6-20091214.jar and poi-ooxml-3.6-20091214.jar to read .xlsx file. but i am getting following errors
The project was not built since its classpath is incomplete. Cannot find the class

Installing programs built with Java

I have a client who installed programs [applications] we built in Java. One person has no problem installing and running the programs. Another can install and run two of the three programs. The third program does not open a dialog box for them to register the program with us. The third person can open one program [the second installs with the first but will not open]; and the third program does not install at all. They all use Windows 2000 5.00.2195 with Service Pack 3. For the program that will not install the task manager indicates that 100% cpu processing time is involved. For the other programs that will not run, they get the javaw.exe error message. A fourth person with Service Pack 4 cannot install any of the programs and gets the wjview.exe generated error and the computer shuts down. This represents money to us if we can solve this problem. I would appreciate any help or suggestions.
Thanks
Donna

* You ship your own JRE for your app
* You get errors from wjview.exe
Based on these 2 evidences, your app is not launched
with your shipped JRE correctly. Perhaps it is
launching the default java and not the full path to
your JRE location? That is at least one of your
problem you need to fix there.
I suggest two probabilities
1) As lichudang says above, launching is not correct. wjview.exe is a component of MS Java, not Sun Java.
2) Possibly these client machines have acquired spyware/adware/viruses. Using wjview to launch these buggers is somewhat common.
Take a look at this thread http://forum.java.sun.com/wireless/thread.jsp?forum=8&thread=351762&start=30&range=15&tstart=0&trange=15 which talks about (2) above.
This Google search turns up quite a few references, try refining it with additional terms

How to parse a string in CVP 7.0(1). Is there a built-in java class, other?

Hi,
I need to parse,in CVP 7.0(1), the BAAccountNumber variable passed by the ICM dialer. Is there a built-in java class or other function that would help me do this?
Our BAAccountNumber variable looks something like this: 321|XXX12345678|1901|M. In IP IVR I use the "Get ICM Data" object to read the BAAccountNumber variable from ICM and then I use the "token index" feature to parse the variable (picture below).
Alternately, IP IVR also has a Java class that allows me to do this; the class is "java.lang.String" and the method is "public int indexOf(String,int)"
Is there something equivalent in CVP 7.0(1)?
thanks

CommunityDiscussion/Forum built in Java......

Good Afternoon,
I need a tool for creating community discussions and searched google, sourceforge, etc for one built in Java. I found the one used here called Jive that was originally an open source project. The Jive open source page was moved to the jivesoftware site where you can buy it. I like what is offered by Jive and would not mind paying the $1500 bucks or so for the license. But, if there is open source I would much rather contribute source code contributions than bucks.
Does anyone know of a similar tool written in Java and open source? Or not open source? One key feature is allowing a user to see only those forums they are authorized to see.
Many Thanks!
Al

Hi Kevin,
Unfortunately, no. I found a few and most were in early stages of development with really basic features. There are some good ones, but not in Java.
We have settled on Jive and will be coughing up the bucks. It seems to be worth it.

Java Icon in titlebar

Hi,
Could some help me out. I an trying to replace the Java Icon in the title bar.
tank you in advance.

Will need to use a third party image loader for ico files. The Java Advanced Imageing API may have support for .ico files, but I have never looked into that.
new ImageIcon("myicon").getImage( )Creates an ImageIcon which is not needed.
java.awt.Toolkit.getDefaultToolkit( ).getImage( "myicon" );
or
java.awt.Toolkit.getDefaultToolkit( ).createImage( "myicon" );Would have the same effect without loading an extra object into memory. Get image will load the image into a buffer so that other calls to getImage will return the same object. Create image will not add it to the buffer.

Our Java application is built with java 1.4 version and oracle 10g

Our Java application is built with java 1.4 version and oracle 10g version database, is it possible to upgrade oracle database to 11g?

is it possible to upgrade
Yes. SE and the other editions have a migration/upgrade utility, not seeing any mention of that program in the XE license docs. To upgrade to 11gR2 from 10g, the 10g instance must be at patch 10.2.0.2 or higher.
So if you're a GUI dba, might be out of luck. But the the XE install has the catalog upgrade scripts that need to be run, there is a MOS note explaining the manual upgrade steps.
Or set up a brand new 11g database instance and datapump your user schema(s) from the 10g instance to the new 11g instance. The database doesn't care what java version you're using, it just does what its told with the data. DDL, DCL, DML ... its not much different. Quite a few new features in 11g.
But if you're after JVMs that piece is not supported with XE.

Where is the Java icon

Hello,
once upon the time - it was at Java 1.4 - the Java icon for windows could be found in the subdirectory \jre\javaws\JavaCup.ico.
Where can that - or a similar - Java icon be found in Java 5 and 6 installations (or elsewhere)?

This is the result of a find in the Java 1.5.0 directory on a Linux system:
# find . -name "*png" -print

./jre/lib/images/icons/sun-java_HighContrast.png
./jre/plugin/desktop/sun_java.png
I suggest you run a similar find on your Java directory and check to see if any of those images (change png to gif and jpg to possibly get more images) suits your needs.
