  - Regular expressions question!I'm trying to parse HTML tables, so I need to find following pieces of text!
    
    <table .....anything between this ..... /table> and

  - Eclipse 3.3 - external tool arguments issue.
    I run the WebSphere command line wsadmin java tool as external tool in
    Eclipse. It works fine except where an External tool argument has an
    "=" sign as in "-javaoption -Dcom.ibm.ws.management.standalone2=xxxx".
    
    Wsadmin picks up the "-Dcom.ibm.ws.management.standalone2" variable
    but not the value. Seems that the Eclipse "arguments" dialog
    truncates values after the "=" sign. Is there a way around this.
    
    The arguments are listed below.
    
    -user 1234 -password xyz
    -lang jacl -host 11.11.11.11. -port 1111
    -javaoption -Dcom.ibm.ws.management.standalone2=xxxx
    -wsadmin_classpath C:\WASAdminSBV\WSAdmin\WAS5.1\JACL\proclib.jar
    -f ${resource_loc}
    
    The problem does not occur when Wsadmin is run from the command line.

  - Advanced Tooltips in JavaHi
    
    I want to implement dynamic interactive tooltips in java so that the
    user can expand / collapse them. Also, if there are hyperlinks in the
    tooltip text, the user should be able to follow up this link. For the
    same purpose, I need to be able to catch any events associated with
    tooltips.
    
    I tried to search a lot on how to customize the behavior of tooltips in
    Java, however couldn't find any useful information. Does anyone know
    about how to proceed about this? Any suggestions / pointers would be
    greatly appreciated.
    
    Thanks,

  - load servlet mappings at runtime in tomcatCan anyone suggest a way to achieve dynamic servlet mappings in tomcat 5.5.
    
    What I want to do is run a web app with any number of paths all pointing to
    one servlet. These paths would be loaded from a database and extra paths
    can be added at runtime by the user. So an example would be
    www.domain.com/sample and www.domain.com/anothersample would both execute
    the same servlet.
    
    Another option I thought of was having a custom 404 servlet that would check
    the request supplied and then redirect.

  - mouseClicked vs. mousePressed on Apple vs. WindowsI'm writing a Swing component which must function similarly on Apple
    and Windows; and am having trouble with which event to fire off of
    (this is effectively a toggle button which would ideally just be
    interested in mouseClicked). For a variety of other reasons, I don't
    want to make my code act on the mousePressed event.
    
    Originally, our QA person asserted that it was busted because she was
    clicking (and moving the mouse > 10 pixels) and it wasn't getting
    "toggled" (this was on Windows). I won the battle there by saying
    "don't move it 10 pixels; that's a drag, not a click". (after
    debugging and figuring out that if you moved the mouse more than
    approximately that much, the mouseClicked never came in).
    
    However, she now claims that on Apple (OSX) that the button fails to
    toggle if you move the mouse even one pixel while pressing the button.
    (i.e. if you are not perfectly still while clicking).
    
    Obviously this would be a different story. I don't have immediate
    access to an Apple machine, so was wondering if anybody else had seen
    this behavior. When I worked on the AWT on OS/2 at IBM, it was fairly
    clear that the mouse events were determined based on native operating
    system events (i.e. when Windows says it is a click, we'll say it is a
    click). Don't know if that's true now or not, since I haven't seen the
    code since Java 1.1.8.

    Symbian is by far the dominant mobile OS worldwide and don't see that
    changing soon, although tons of linux phone shipments to china, which
    has the largest mobile subscriber base in the world holds hope.
    
    As always, Java ME is the application platform for all these devices.

  - Ultimate enterprise design pattern for 3 tiered appsSo, I feel I am close here is what I have so far.
    
    Goal: Database driven selection of controls on forms
    Goal: Business rules only aware of interfaces
    Goal: Presentation layer only aware of interfaces
    
    Database Table Person: Name, BirthDate, Gender, CreateDate, CreatedBy
    
    Value Object:
    
    public class Person {
    private String name;
    private DateTime birthDate;
    private int gender;
    private DateTime createDate;
    private int createdBy;
    }
    
    Business Layer Object:
    
    public interface IPersonModel {
    public boolean isTeenager();
    public boolean isMale();
    public boolean isFemale();
    }
    
    Presentation layer Multi Column List control
    
    public interface ITableList {
    public int rowCount();
    public Object getItemAtRow(int row);
    public Object getValueAtRowColumn(int row, int column);
    }
    public interface ITableItem {
    public Object getValueAtColumn(int column);
    }
    
    The most complex part is storing in a database table which fields on
    the value object will be presented in the multi column list control.
    It needs to be user friendly and maintainable.
    
    One time I tried having each value object with a switch statement for a
    unique number for each field. So the database contents and source code
    are kept in synch e.g. 266 in the database means 'Person CreateDate'
    and the value object returns that when implementing ITableItem.
    It worked but relies on a code generator to make it all work.
    
    This time around I thought I could keep a script in the database so the
    user would pick the first column to be person.getCreateDate(), the
    second to be person.getName() etc.
    Using reflection I could generate on the fly which attribute will be
    displayed in which column.
    
    Anyone think of other options?
    
    The other thing I need to change is it seems an unecessary dependency
    for the value object to implement ITableItem - there probably needs to
    be another class which does it and depending on the database values
    pulls the data from the value object.
    
    The same goes for the value object implementing the business rules.
    While probably not too bad if it does, perhaps mapping the values to
    something that does might work better.
    
    Apart from the value object I am trying to anything else in all the
    code knowing about fields which are only used for CRUD e.g. createDate.
    CreateDate may never be used for logic - in my app - ever - so why
    pass it around as business objects - better to only have things
    implementing interfaces where needed.
    
    What do you think so far?

  - using jsp:setProperty on non-simple types.Hi,
    
    I'm currently having a small problem with my application. I'm using
    some simple classes that wraps simple types to help me provide multiple
    representation. For example, a DateCBO calls wraps the Date type and
    gives me the oportunity to have various 'getters' like
    getDateShortFormat(), getHtml(), getDateLongFormat() and so on.
    
    My beans are using this kind of wrappers as their properties.
    
    I have already made a custom tag to retrieve information that i use
    instead of the standard jsp:getProperty
    Now, i'm trying to use the jsp:setProperty to initialise the bean
    property, but i have 'Could not coerce String to non-primitive type
    StringCBO without bean property editor (JSP 1.2: 2.13.2.1) at line 13'
    error.
    
    Is there an interface that i can use to allow direct usage of
    'jsp:setProperty', or should i create a custom tag as well.
    
    thanks.

java-programmer, [encoding]Stupid question regarding encoding I have written a java plugin for an application that reads a file to execute
a series of actions ; when I parse my text file I check for the existence
of the following line "#HEADER" ; it works fine on my equipment ; on
Windows somebody working with the text file encoded in utf-8 told me that
there is problem as the line containing "#HEADER" is not found !

Now I am a little bit puzzled about all this :

(a) when you write java code and compile it what happens to the
string "#HEADER" because it will be used in the following test :
if (line.equals("#HEADER") {...}
where line is read from the text file with encoding as is on the machine
where the class is executed ? in other words you are comparing what to
what ?

(b) when with a Java app you read a text file can you get its encoding
format like utf-8 or ANSI or whatever to decide about some actions to be
taken ?

I think the problem could be easily solved by replacing "#HEADER"
by "_HEADER" but I have to go to the bottom of this to understand what is
going on.
Thanks

  - Accessing the name of the CLASS/JAR file invokedHello,
    
    I am trying to pack all my files into a JAR - this includes CLASS
    files and other textual files such as help, std configs, etc.
    
    I would like to be able to extract them from the Java app straight out
    of the JAR - and for this I need to know what the name of the JAR file
    invoked was (it might have been renamed for X reasons)
    
    Is there any sure way to do this? (the alternative is to have an
    external file to contain said data, but I want to know if a way to
    have everything self-contained exists, first)

  - JSpinner causes trouble to JB 2005 designer...X-No-Archive: yes
    Hi.
    
    I try to build a GUI with the JB 2005 designer (JB 2005
    Enterprise-Trial/Fondation version).
    Basically it works until I want to add a JSpinner component. Then this
    error happens: "null processing BeanInfo class
    javax.swing.JSpinnerBeanInfo"
    The component is not added. So I add it manually. But the rest of the
    GUI components (following the JSpinner member variable) is mixed up
    then.
    
    Is there a workaround to this? Thanks.

  - JButton layout - equal width with no absurd stretchThank you for taking the time to enlighten me. I have been searching
    and trying different things but nothing seems to work for me. All I
    want to do is have a column of JButtons to the left of a JScrollPane.
    I want the buttons to have equal widths (the widest button at its
    minimum text-fitting width, all others stretched to an equal width) and
    be only as high as they need to be for their text. The scroll pane can
    fill the rest of the width (and height for that matter). Something
    like this:
    
    +----------------------------------+
    | |
    | +--------+ +-------------------+ |
    | | A | | | |
    | +--------+ | | |
    | | ABCDEF | | | |
    | +--------+ | JScrollPane | |
    | | ABCD | | | |
    | +--------+ | | |
    | | | |
    | +-------------------+ |
    | |
    +----------------------------------+
    
    I tried box layout, but then the buttons are not equal widths. Border
    layout makes the buttons equal widths, but stretches them to be as high
    as the scroll pane. Grid layout stretches them both vertically and
    horizontally. I think I tried gridbag layout and had the same problem
    as grid layout. The type of layout I want for the buttons reminds me of
    how a table would layout in an HTML document. I want to avoid using
    literal size values because of L&F issues on other platforms. Shrinking
    the height of the scroll pane is not an option. Does anyone have any
    suggestions?

  - DOM tree questionHi all,
    
    For code sample domEcho02.java, every element node will have an empty text
    node like below. looks like there is no direct method in the treemodel impl
    or in the adaptor class that I can control this. how can I get rid of it?
    
    // sample xml node
    <pnode attr1='0'>
    <cnode1 att1='attr'><value>blah</value></cnode1>
    </pnode>
    
    // will be translated in tree nodes
    element: pnode
    text: (empty, unnecessary)
    element: cnode1
    text: (empty, unnecessary)
    element: value
    text: blah
    
    //should be
    element: pnode
    element: cnode1
    element: value
    text: blah
    
    TIA

  - Serial Port CommunicationsI have a java application that I wrote that collects data from a
    serial port on a laptop from a data collection device. Program works
    well.
    
    My bosses would like certain conditions to draw more attention than
    just using the laptop's monitor. They would like two lights and a horn
    to be controlled as well.
    
    Tackling the serial input device was pretty easy, but I am not sure
    where to start with this request.
    
    1) I only have one serial port on the Laptop, but they want to control
    4 devices (horn, light 1, light 2, data collection device). So how
    do I handle that?
    
    2) Where would I go to buy the other devices and what device would I
    have my java program talk to in order to control them?
    
    Thanks,

  - grabbing text from non-edit java windowHow do I get the text (in a java program) from a java window that is not an
    edit window (ie, cannot hilight the text with a mouse)? ie, is there
    something similar to in functionality to Windows API GetWindowText()?

  - Is Java really faster than Obj-C ? Should Apple dump Obj-C and go with Java?The old notion that Java on desktops is slow might have to go out the
    window if more studies show this:
    
    http://homepage.mac.com/spullara/rants/C1464297901/E775622191/index.html
    
    Again, this points out the fact that there will probably be a
    renaissance of Java on desktops as it percolates on Linux and Macs and
    Windows desktops. We use Mac OS X iMacs at work and Java apps as
    MoneyDance (a personal finance software that runs on all 3 desktops,
    although it looks sorta crappy in windows) are very good looking and
    extremely fast.
    
    Now, if only IBM's open source eclipse made better looking SWT apps on
    Mac and Linux...

  - Weird Problem w/ DecimalFormatThe following code snippet:
    
    static DecimalFormat nf=new DecimalFormat("#####.00");
    System.out.println(nf.format(1000.10));
    
    sometimes stops working properly and instead of seeing 1000.10 I see 1000,10
    (note the comma). I can't for the life of me figure out what is going on...
    I'm using Java 1.3.1 on a Sun workstation.
    
    Any ideas?

  - BPEL Products(Business prcess execution Language 4 webservices)Hi,
    I had a few questions about BPEL products
    1) Can you let me know the BPEL Servers available in the market. Do
    these need to be integrated with J2EE appservers or can they run as is
    if all I want to do is integrate a few Java applications and
    webservices to the flow.
    2) How powerful are Weblogic Integration suite and Websphere MQSeries
    Integrator for integrating Webservices using BPEL. Also how easy is it
    to develop this kind of flow. Collaxa has a more pure BPEL product
    that seems easier for the above task.
    
    Thanks in Advance,
    Regards,
    Rahul
