How to use xpress to create an array?

I am trying to delete some accounts in workflow. When I try to get all these accounts from repository. I find in com.waveset.session.session,the method listUsers(Attributecondition[] conds) is the best for me. But I don't know how to create an array of type attributecondition.
Can somebody help me?

just invoke toarray method on java.util.arrayList by passing attribute conditions as list...
Attribute conditions are just example only..

How to use SNRO to create daily number range?

Dear all,
I would like to know how to use SNRO to create a daily number range.
We would like to have the following sequence. The first 8 digits are date and the last 2 digits are number sequence. Each day, the last 2 digits will start from 01 again. i.e. <8-digits date><2-digit sequence>
For example, today is 22 May 2006,
2006052201
2006052202
2006052203
Tomorrow will have sequence like this:
2006052301
2006052302
2006052303
Thanks!

Thomas,
I don't there is a automated way of doing as the dates do NOT follow a numbering sequence. What you can do is to create a number range for getting the last two digits every day and manually concatenate the date with the serial number.
However, as you have to reset the counter every day that might be a issue.

Ravi

I was wondering how to use Dreamweaver to create joomla template? Any ideas or useful resources.

I am embarking on a new project to create a joomla template. I need your ideas on how to use Dreamweaver to create the template. TQ

It's pretty much the same procedure with all your open source CMSs (WordPress, Drupal, Joomla!...)

How to use the dll created by c++ but not write a jni wrapper around

how to use the dll created by c++ but not write a jni wrapper around through a java program. now I can't access that dll like this directly from java.

Your question is unclear. (You haven't said what dll you are talking about.)
But:
If you are talking about an existing dll, then the only alternative to writing a wrapper is to use one of the wrapper generators floating around. Do a search on JACE.
If you are talking about a dll you are writing, then run jah and get the interface to match java right away; then you won't have to write a wrapper.

How to use HorizontalList populated with an Array of Image?

Is it possible to populate a HorizontalList with an Array of
Image? I am trying to create a HorizontaList of Images (thumbnails)
using a dynamic method where I put each thumbnails found into an
Array and then indicating to the HorizontalList to use the Array as
the dataProvider. The result is that I just see the ID generated
for each Image.
Since I am controlling the content of the HorizontalList into
the mx:source, I am a bit confused how to use the itemRenderer
property.
Any help will be appreciated since Google don't show a lot of
example/problems like mine at this moment!

Hi,
Just set the itemRenderer property to mx.controls.Image and
you should be done.

How to use a session, created in a jsp page, in a php page

Hello, forgive me for the newbie question.
Here is my problem:
I want to have a jsp page create a session, set some session variables and then redirect to a php page which will access those same session variables.
I have the redirection worked out, but I can't seem to find out how to use the jsp session in my php script.
Is this possible at all, and if so, how does it work?

Note that javascript runs on the client side, and JSP runs on the server. JSP and the session objects are NOT available to javascript in reaction to the user.
If this function is called only when the page is first created, not when the user interacts with the page, or if you want that value to be constant with respect to the javascript, then you can do this:
<%
String someValue = (String)session.getAttribute("theAttributeName");
%>
<script type="text/javascript">
     Calendar.setup({inputField:"f_date_dfFirstPmtDate",
                                          button:"f_trigger_dfFirstPmtDate",
                                         singleClick:true,
                                          ifFormat:<%=someVale%>});
</script>

Using JLabel[] to create an array of image labels

Hello, I am quite new to Java so I am not sure if the following is even the best way to do what i am trying to do ... but please advise:
I am making a JLayeredPane mapArea with grid lines where the user will be able to change the scale of the map and the grid lines can move along. The way I approached it is to create JLabel arrays that contains every single gird line i am going to use, add them to the map panel at the bottom-most layer and position them according to the scale. Below is the code that I wrote:
int i = 0;     //local index variable for the for loops below
JLabel[] vlineArray = new JLabel[50];
JLabel[] hlineArray = new JLabel[50];
ImageIcon[] vlineImageArray = new ImageIcon[50];
ImageIcon[] hlineImageArray = new ImageIcon[50];
for( i=0; i<50; i++ ){
     vlineImageArray[ i ] = new ImageIcon(GUI.class.getResource("vline.gif"));
     hlineImageArray[ i ] = new ImageIcon(GUI.class.getResource("hline.gif"));
// vertical line array
     for( i=0; i<50; i++){
     vlineArray [ i ] = new JLabel(vlineImageArray[ i ]);
mapArea.add(vlineArray[ i ],1);
// horizontal line array
for( i=0; i<50; i++){
     hlineArray [ i ]= new JLabel(hlineImageArray[ i ]);
     mapArea.add(hlineArray [ i ],1);
}}I tried to position these Jlabels in the array using setBounds:
i.e. vlineArray.setBounds(......)
But nothing showed... But if I simple create a vline by itself and add it to the map pane and setBounds. The vline shows up fine:
// this works
JLabel vlineImage = new JLabel(vline);
mapArea.add(vlineImage);
vlineImage.setBounds(.....);I also tried to post at the java programming forum
http://forum.java.sun.com/thread.jspa?threadID=646495&tstart=15
But nothing worked.
Please help! Thanks a bunch!

if I were going to draw grid lines over a map area, I would put a component the size of the layered pane in the layered pane which is transparent and can be given a scale and can override the paint method to paint the lines directly instead of trying to handle lots of labels like you're doing.

How to use cdrw to create multi-session cd?

I use cdrw to create multi-session cd as this:
# cdrw -O -i /tmp/1.iso
contents in 1.iso can be read by both Solaris and Windows, then
# cdrw -O -i /tmp/2.iso
Solaris consider the cd is empty and Windows consider the cd is not existed.
My question is, how to handle multi-session cd in Solaris? From some cdrecord FAQ, the data was there but TOC was broken, so one tip is importing TOC of previous sessions before burn. But how?

Honestly I know this is sort of a weak point with Macs. Not really sure why. I guess with the price of HD storage getting cheaper as well as writable media it's just not something people are interested in enough. But that's too bad because it does seem to have interest.
Anyway you might check out Burn Again

How to use LT03 to create TO by WBS delivery

Hi,
I have a WBS delivery, when I use LT03 to create a TO by this delivery, I can see the WBS field is empty, and gray. how to let me go ahead to create a WBS TO?
Thanks.

If the LIPS fields don't have the special stock data, then your delivery is not related to special stock. Consequently, the TO cannot have special stock data too.
If you expected that project stock should be picked and issued through the delivery, it's better you check the preceding documents, master data and configuration, something may have gone wrong.

How to use search index created by jhindexer

Hi i have created a JavaHelp set using Docbook which works ok but the search doesnt work. I then discovered jhindexer and have sucessfully used it to create a directory called index containing the index (DOCs,DOCS.TAB etc) in the same directory as the html files but it still doesnt work.
I guess i have to modify one off my javaHelp files (jhelpidx.xml,jhelpset.hs) to point to this index but cant find any info on this.
Can anyne help me please.

place the snippet below into your HelpSet File (.hs), the helpset file should be in the same directory as the JavaHelpSearch folder where your index files are located. See the structure:
/foo.hs
/JavaHelpSearch/DOCS
/JavaHelpSearch/OFFSETS
---- snippet -----
<view>
<name>Search</name>
<label>Suche</label>
<type>javax.help.SearchView</type>
<data engine="com.sun.java.help.search.DefaultSearchEngine">JavaHelpSearch</data>
</view>
---- snippet -----
And read the supplied PDF documentation, because if you have problems with this, you will have even more problems with some more advanced stuff.

How To: Use reflection to create instance of generic type?

I would like to be able to use reflection to instantiate an instance of a generic type, but can't seem to avoid getting type safety warnings from the compiler. (I'm using Eclipse 3.1.1) Here is a trivial example: suppose I want to create an instance of a list of strings using reflection.
My first guess was to write the following:
Class cls = Class.forName("java.util.ArrayList<String>");
List<String> myList = cls.newInstance();The call to Class.forName throws a ClassNotFoundException. OK, fine, so I tried this:
Class cls = Class.forName("java.util.ArrayList");
List<String> myList = cls.newInstance();Now the second line generates the warning "Type safety: The expression of type List needs unchecked conversion to conform to List<String>".
If I change the second line to
List<String> myList = (List<String>)cls.newInstance();then I get the compiler warning "Type safety: The cast from Object to List<String> is actually checking against the erased type List".
This is a trivial example that illustrates my problem. What I am trying to do is to persist type-safe lists to an XML file, and then read them back in from XML into type-safe lists. When reading them back in, I don't know the type of the elements in the list until run time, so I need to use reflection to create an instance of a type-safe list.
Is this erasure business prohibiting me from doing this? Or does the reflection API provide a way for me to specify at run time the type of the elements in the list? If so, I don't see it. Is my only recourse to simply ignore the type safety warnings?

Harald,
I appreciate all your help on this topic. I think we are close to putting this thing to rest, but I'd like to run one more thing by you.
I tried something similar to your suggestion:public static <T> List<T> loadFromStorage(Class<T> clazz) {
    List<T> list = new ArrayList<T>();
    for ( ...whatever ...) {
       T obj = clazz.newInstance();
       // code to load from storage ...
       list.add(obj);
    return list;
}And everything is fine except for one small gotcha. The argument to this method is a Class<T>, and what I read from my XML storage is the fully qualified name of my class(es). As you pointed out earlier, the Class.forName("Foo") method will return a Class<?> rather than a Class<Foo>. Therefore, I am still getting a compiler warning when attempting to produce the argument to pass to the loadFromStorage method.
I was able to get around this problem and eliminate the compiler warning, but I'm not sure I like the way I did it. All of my persistent classes extend a common base class. So, I added a static Map to my base class:class Base
   private static Map<String, Class<? extends Base>> classMap = null;
   static
      Map<String, Class<? extends Base>> map = new TreeMap<String, Class<? extends Base>>();
      classMap = Collections.synchronizedMap(map);
   public static Class<? extends Base> getClass(String name)
      return classMap.get(name);
   protected static void putClass(Class<? extends Base> cls)
      classMap.put(cls.getName(), cls);
}And added a static initializer to each of my persistent classes:class Foo extends Base
   static
      Base.putClass(Foo.class);
}So now my persistence code can replace Class.forName("my.package.Foo") with Base.getClass("my.package.Foo"). Since Foo.class is of type Class<Foo>, this will give me the Class<Foo> I want instead of a Class<?>.
Basically, it works and I have no compiler warnings, but it is unfortunate that I had to come up with my own mechanism to obtain a Class<Foo> object when my starting point was the string "my.package.Foo". I think that the JDK, in order to fully support reflection with generic types, should provide a standard API for doing this. I should not have to invent my own.
Maybe it is there and I'm just not seeing it. Do you know of another way, using reflection, to get from a string "my.package.Foo" to a Class<Foo> object?
Thanks again for your help,
Gary

How to use BAPI_REQUISTION_CREATE to create pr account cat is space

Hi expert !
I try to use BAPI_REQUISTION_CREATE to create PR which account cat is space (Inventory PR) but I found error commitment check that it seem I don't pass FUNDS and FUND_CENTER data but I pass it to table PRACCOUNTASSIGNMENT.
