Winhelp support in a Java program

Hello,
Of the several products we develop, one, a Java program, uses
the Java Help help system (logically). The others use a standard
Winhelp help system (developed in Robohelp). Our current workflow
for developing a help system for the Java program is to batch
convert the Winhelp RTF files into HTML files. The problem is, most
of our Winhelp formatting is either dropped or incorrectly
represented in the Java help file. Also, I prefer the look and feel
of a Winhelp system over Java.
Is it possible for a Java program to be modified so that it
supports a Winhelp help system and not a Java Help system? If so,
how is this done, and where can one find information on the
process?
If not, what options do we have to "pretty up" the Java
output from the conversion?
Thanks!
Todd

Surely the whole point of javahelp is that it is cross
platform? Winhelp is for Windows only so I cannot see how it would
be possible unless someone has produced some sort of converter. I
am not aware of one but perhaps Google can help.
Why can't you just generate javahelp from your project? That
should keep the formatting. There's a topic on my site about
javahelp but it is aimed at RH HTML users. Nonetheless there may be
something in that is of help.
I assume you are aware that winhelp will be more problematic
under Vista? Your users will be able to download a viewer but you
will not be allowed to distribute it.

          WLS JMS supports the clients developed by using non-java program languages,such
          as,c++,VB?


The short answer is yes. This is a frequently asked question. I
          suggest searching this newsgroup in google using terms like "C++",
          "IIOP", ".NET", "JCOM".
          Note also that WL 8.1 (now out in beta) contains a thin java client
          (something like 0 or 300K without JMS, 700k with. The 0K client comes
          from leveraging WL's IIOP support.)

Thanks for your response. Could you direct me to a resource that explains the steps for accomplishing this? I'll need to provide the development staff with instructions.
Thanks again!

Challange for you, help for me! java program

Catalogue Manager II
Specification:
1.     Develop an object to represent to encapsulate an item in a catalogue. Each CatalogueItem has three pieces of information: an alphanumeric catalogue code, a name, and a price (in dollars and cents), that excludes sales tax. The object should also be able to report the price, inclusive of a 15% sales tax, and the taxed component of the price.
2.     Data input will come from a text file, whose name is passed in as the first command-line argument to the program. This data file may include up to 30 data items (the program will need to be able to support a variable number of actual items in the array without any errors).
3.     The data lines will be in the format: CatNo:Description:Price Use a StringTokenizer object to separate these data lines into their components.
4.     A menu should appear, prompting the user for an action:
a.     Display all goods: this will display a summary (in tabulated form) of all goods currently stored in the catalogue: per item the category, description, price excluding tax, payable tax and price including tax.
b.     Dispfay cheapest/dearest goods: this will display a summary of all the cheapest and most expensive item(s) in the catalogue. In the case of more than one item being the cheapest (or most expensive), they should all be listed.
c.     Sort the list: this will use a selection sort algorithm to sort the list in ascending order, using the catalogue number as the key.
d.     Search the list: this will prompt the user for a catalogue number, and use a binary search to find the data. If the data has not yet been sorted, this menu option should not operate, and instead display a message to the user to sort the data before attempting a search
5.     Work out a way to be able to support the inc tax/ex tax price accessors, and the tax component accessor, without needing to store any additional information in the object.
6.     Use modifiers where appropriate to:
a.     Ensure that data is properly protected;
b.     Ensure that the accessors and mutators are most visible;
c.     The accessors and mutators for the catalogue number and description cannot be overridden.
d.     The constant for the tax rate is publicly accessible, and does not need an instance of the class present in order to be accessible.
7.     The program should handle all exceptions wherever they may occur (i.e. file 1/0 problems, number formatting issues, etc.) A correct and comprehensive exception handling strategy (leading to a completely robust program) will be necessary and not an incomplete strategy (i.e. handling incorrect data formats, but not critical errors),

One thing you're missing totally is CatalogueItem!! A CatalogueManager manages the CatalogueItem's, and is not an CatalogueItem itself. So at least you have to have this one more class CatalogueItem.
public class CatalogueItem {
private String catalogNumber;
private String description;
private double price;
//with all proper getters, setters.
Then CatalogueManager has a member variable:
CatalogueItem[] items;
Get this straight and other things are pretty obvious...

How to fetch %ROWTYPE OUT param of a stored procedure from Java program?

I have a stored procedure that has IN / OUT parameter as table_name%ROWTYPE.
From a java program how can I access this ROWTYPE variable?
I tried all possible documentation and none of the explains whether or not this is supported.
My use case expect exactly 1 record from the procedure and we would prefer not to use REF CURSOR.
Is there a way to achieve this? If so, can someone help me with it by posting the sample code to achieve this?
I tried all the possible OracleTypes to register the OutParameter and they all fail.
Looks like there isn't any equivalent of %ROWTYPE in OracleTypes either.
If you need, I can post my sample procedure that uses %ROWTYPE as OUT parameter.
I really appreciate your help in this regard.

Hi,
If "returning only 1 record" the showstopper for not using Ref Cursor, you might want to reconsider because as you probably know, the ref cursor is only a pointer and requires additional step to retrieve the data.

Using a UNIX shell script to run a Java program (packaged in a JAR)

Hi,
I have an application (very small) that connects to our database. It needs to run in our UNIX environment so I've been working on a shell script to set the class path and call the JAR file. I'm not making a lot of progress on my own. I've attached the KSH (korn shell script) file code.
Thanks in advance to anyone who knows how to set the class path and / or call the JAR file.
loggedinuser="$(whoami)"
CFG_DIR="`dirname $0`"
EXIT_STATUS=${SUCCESS}
export PATH=/opt/java1.3/bin:$PATH
OLDDIR="`pwd`"
cd $PLCS_ROOT_DIR
java -classpath $
EXIT_STATUS=$?
cd $OLDDIR
echo $EXIT_STATUS
exit $EXIT_STATUS

Hi,
I have an application (very small) that connects to
our database. It needs to run in our UNIX environment
so I've been working on a shell script to set the
class path and call the JAR file.
#!/bin/sh
exec /your/path/to/java -cp your:class:paths:here -MoreJvmOptionsHere your.package.and.YourClass "$@"Store this is a file of any name, e.g. yuckiduck, and then change the persmissions to executechmod a+x yuckiduckThe exec makes sure the shell used to run the script does not hang around until that java program finishes. While this is only a minor thing, it is nevertheless infinite waste, because it does use some resources but the return on that investment is 0.
CFG_DIR="`dirname $0`"You would like to fetch the directory of the installation out of $0. This breaks as soon as someone makes a (soft) link in some other directory to this script and calls it by its soft linked name. Your best bet if you don't know a lot of script programming is to hardcode CFG_DIR.
OLDDIR="`pwd`"
cd $PLCS_ROOT_DIRVery bad technique in UNIX. UNIX supports the notion of a "current directory". If your user calls this program in a certain directory, you should assume that (s)he does this on purpose. Making your application dependent on a start in a certain directory ignores the very helpful concept of 'current directory' and is therefore a bug.
cd $OLDDIRThis has no effect at all because it only affects the next two lines of code and nothing else. These two lines, however, don't depend on the current directory. In particular this (as the cd above) does not change the current directory for the interactive shell your user is working in.
echo $EXIT_STATUS
exit $EXIT_STATUSEchoing the exit status is an interesting idea, but if you don't do this for a very specific purpose, I recommend not to do this for the simple reason that no other UNIX program does it.

Running the Java program as service.

Hi,
I want to create have java program, which runs continously. This would hit check a table in Database for any new records and if there is anything it would post a message to another service. It would keep track of how many messages were posted and how many were completed at any point of time.I should have the ability to stop this service. When a stop sequence is initiated, it should wait till all the messages are processed and shutdown. I am looking for inputs on how to invoke the java program as service and the second part (stopping the service). I dont want to Java wrapper service or commons daemon api. I am on JDK 1.4.2
Thanks in Advance.
Regards,
Arul.

Do you want to write a daemon? I dont think you can do it without some explicit OS support..
Well, lemme know if you find a way

Running curl command from a java program using Runtime.getRuntime.exec

for some reason my curl command does not run when I run it from within my java program and errors out with "https protocol not supported". This same curl command however runs fine from any directory on my red hat linux system.
To debug the problem, I printed my curl command from the java program before calling Runtime.getRuntime.exec command and then used this o/p to run from the command line and it runs fine.
I am not using libcurl or anything else, I am running a simple curl command as a command line utility from inside a Java program.
Any ideas on why this might be happening?

thanks a lot for your response. The reason why I am using curl is because I need to use certificates and keys to gain access to the internal server. So I use curl "<url> --cert <path to the certificate>" --key "<path to the key>". If you don't mid could you please tell me which version of curl you are using.
I am using 7.15 in my system.
Below is the code which errors out.

Error in ONS logs while implmenting FCF on oracle RAC from java program

I have java prog on client machine that uses properties from a property file.While making the connection to the ONS port on the oracle RAC server to implement FCF the program is throwing error as below:

Java program/package in project tree

On a fairly large web services project I am working on I started using
workshop to develop a couple of straight java programs and put them in the
project tree right next to the jws programs. This worked great, I could
take advantage of the debugging and code completion type editing capability
in Workshop. Last week I moved this source code, plus all of the common
classes, into a directory under the top level project directory
(com/myCompany/api/structures and com/myCompany/api/util) and copied the
programs into there (Workshop changed the package names appropriately). It
all ran fine.
This week another developer got the latest pull from source control with the
directory mentioned above but cannot build. The message is "Package
com.myCompany.api.util not found in import". I am looking right at the file
structure and is the same as on the original machine that it was built on.
Any idea why it cannot find that file/directory/package?
Is there anyway to forceworkshop to build a java program? The build menu
command is disabled when working on a java file.
It would be great to have a section in the support docs about writing java
classes in Workshop. We are determined to keep our jws's (what's the plural
of jws!) lean and use helper functions and/or business object/model
functionality for the bulk of the work. I know V1 of workshop has not
focused on this java editing capability but it is there and it's pretty
strong. Without this you have
to work in a seperate IDE to write helper classes do a build there and then
come back to Worskhop.
I'd like to know things like 1) when and how does workshop decide to do a
build of the java classes 2) is it possible to put other source code like
libraries somewhere so that I could debug right into these? and 3) how does
workshop resolve it's package structure at build time (other than
web-inf/classes)?
Thanks!

Well, our problem seems to be fixed but I'm not sure why. The java classes
had not been deleted from the top of the project tree. When we deleted them
suddenly the import started working ... go figure ... maybe it was something
else we did. I would still be interested in answers to my more general
questions about java source in workshop if possible ...
thx

Passing Japanese characters to Java program

Hi,
I am using Java POI APIs for creating/modifying excel spreadsheets. The platform is Solaris. The data to be populated contains both English as well as Japanese characters. The input data to Java program comes from a perl program. When I populate the data in excel or even print using System.out.println, it prints ???... for Japanese characters. The data is in SJIS format.
I tried converting it to UNICODE in java but that doesn't seem to be working.
I also tried using native2ascii for converting the data to UNICODE before it is fed to Java program using the following command
native2ascii -encoding SJIS <Input File> <Output File>
Although it converts the charaters into UNICODE correctly in the form \u8a3c\u523... but when it is input to Java, the program prints the string as such.
But if this string is hardcoded in the program, the Japanese characters are printed correctly.
Could anybody please throw some light as to the data should actually be passed to the Java program.
Thanks

Sekhar
Ive realised the solution will probably involve HttpServletRequest.setCharacterEncoding.
Im now upgrading to Tomcat 4 because 3 didnt support this method. Once I'm through the upgrade, I'll try Japanese the chars again.
I would guess I need to force my web pages to utf-8 and use HttpServletRequest.setCharacterEncoding(utf-8) in the servlet to get it working ?

I need to call a java program and pass parameters from C#

I'm new to C# and was given a project to rewrite some of my old VB.net programs to C# to help me learn. These VB programs call quite a few .bat files that have calls to java programs in them. I'm doing okay converting my VB code, but I've been
stumped for days trying to figure out how to call java from C#.
Does anyone here know how to do this? I really should've had this figured out by now and my back is to the wall. Ugh :(
This is the line from the .bat file that I need to convert to C#.
call jvbat production_r115.Automotive m:\data\MK115mn.100 m:\data\MK115mn.101 %6
There is one parameters being passed, %6
I would be forever grateful if someone can show me how to do this!

Hi Joni,
Do you mean call a bat file that it is a Java program from C#? If so, there is an article talking about it.
If that's not what you're trying to do, please be more specific about what you're trying to do.
http://www.c-sharpcorner.com/UploadFile/maheswararao/CallingJavaProgramfromCS12062005233321PM/CallingJavaProgramfromCS.aspx
Now the next issue is pass some parameters from C#.
The above article tells using Process.Start() method to call java program. Also in this class, you could specify them all in the
Arguments property:
var p = new Process();
p.StartInfo.Arguments = string.Format("{0} {1}", argument1, argument2);
For more detailed information, please refer to
C# Passing Multiple Arguments to BAT File
