Add states with ActionScript, because MXML states occupying space

I have my States setup with MXML fine, but I noticed that even though the State is not currently set, it is occupying space and leaving a huge empty gap in my layout.
I want the State to not occupy the space when it is not the active State.
I think using ActionScript to dynamically add the State when it is needed will solve the problem. What is the ActionScript code to add States (to replace all the State MXML code below)?
<mx:Labe text="No State should be visible and don't occupy any space" />
<mx:states>
<mx:State name="{displayThisState}">
<mx:AddChild>
</mx:AddChild>
</mx:State>
</mx:states>
Thanks.

I'll recommend you to use a ViewStack instead of States, States in Fx 3 are kinda diffucult to declare and manage as your app grows. Fortunately in the Flex SDK 4 there will be a much simpler syntax to declare states.

Changing states with actionScript

Hi,
I have some states set up in my app using MXML as per the
script sample below. This is of course very handy, but upon
changing from one state to another I want to include some
actionScript to make a few things happen when the state changes. I
know that I have full control over states in AS but can I set up
the states as below using MXML and then use AS just to perform the
change. Currently, selecting a new item in a dataGrid calls the
change (change="currentState='editProperty'") but I'd prefer to
have this (change="editProperty()") which would call an AS function
to do some work and *then* change the state. Any help appreciated
as usual,

<mx:states>

<mx:State name="editProperty">
<mx:SetProperty target="{props}" name="height"
value="262"/>
<mx:SetProperty target="{props}" name="x"/>
<mx:AddChild position="lastChild">
<mx:VBox width="100%" height="100%">
-- various controls etc. here --
</mx:VBox>
</mx:AddChild>
</mx:State>
</mx:states>
cheers,
Mike

You could write an actionscript method which takes any class
that extends UIComponent. This includes Application, Canvas, Panel,
etc...
All have a current state
I actually have some code which does just that
package com.domain.ecommerce.admin
import mx.events.ItemClickEvent;
import mx.controls.Alert;
import mx.core.UIComponent;
public class StateManager
* changes the current state based on anything that will
generate an ItemClickEvent...
* For exmaple: <mx:LinkBar
itemClick="StateManager.chooseState(targetComponent,event)" >
... </mx:LinkBar>
* note: this is the object the link bar is located in ...
public static function chooseState(component:UIComponent,
event:ItemClickEvent) : void {
component.currentState = event.label;
public static function
chooseStateByString(component:UIComponent, newState:String) : void
component.currentState = newState;
You can do something like :
click="StateManager.chooseStateByString(this, 'newState');"

Create remoteObject with ActionScript, not MXML

I want to use remoteObject with ActionScript only, no MXML:
private function initializeRemoteObject():void {
            _remote = new RemoteObject();
            _remote.source = "AMFProxyObject";
            _remote.endpoint = "http://localhost/linktoMyAMFServer";
            _remote.destination = "zend";
            _remote.showBusyCursor = true;
public function getIAllData():void {
            initializeRemoteObject();
            var token:AsyncToken = _remote.getAllDataFromStoryTable();
            //token.result = getDataHandler;
I am stuck here because I don't know the proper syntax to handle the result
private function getDataHandler ()void
///////////////    I just want to convert the MXML code below to ActionScript   \\\\\\\\\\\\\\\\\\\\\\
<mx:RemoteObject id="zendRemoteObject" destination="zend" source="AMFProxyObject"
        endpoint="http://localhost/linktoMyAMFServer"
        result="resultHandler(event)">
        <mx:method name="getAllDataFromStoryTable" result="getDataHandler(event)"/>
        </mx:RemoteObject>
Thanks very much. This is driving me nuts, particularly since I couldn't find any help online by googling.

Try using a Responder, specifically an AsyncResponder.
   var token:AsyncToken = _remote.getAllDataFromStoryTable();
   var responder:AsyncResponder = new AsyncResponder( resultHandler, faultHandler );
   token.addResponder( responder );
   public function resultHandler( event:ResultEvent, token:Object=null ):void
      Alert.show( "RESULT: "+ event.result as String );
   public function faultHandler( event:FaultEvent, token:Object=null ):void
      Alert.show( "FAULT: " + event.fault.message );

Is it possible to add paragraphs with actionscript?

If I have an object like
<s:RichText id="foo">
<s:content></s:content>
</s:RichText>
Can I manually add paragraphs to it with actionscript?
I want to manually create a new paragraph, assign a string to it, and then stash it in the RichText object. So I can use a loop to create as many paragraphs as I might need.
Such as
for each (s:String in myCollection) {
   [ foo add a p element with s in it ]

I think I've got it:
var textFlow:TextFlow = new TextFlow();
for each ( var s:String in instructionsArray)
     var p:ParagraphElement = new ParagraphElement();
     var span:SpanElement = new SpanElement();
     span.text = s;
     p.replaceChildren(0, 0, span);
     textFlow.replaceChildren(textFlow.numChildren, textFlow.numChildren, p);
instructionText.content = textFlow;
Where "instructionText" is a RichText object.
This is very, very cool, btw.

AdvancedDataGrid - Add columns with ActionScript

I'm trying to add columns to an AdvancedDataGrid via ActionScript.
I can't get it to work.
I've tried two approaches -- One with an intermediary array to store the columns then set the adg's columns to the array; One where I assign the columns directly to the adg's columns array.
They both fail in their own way. The columns don't "take" and the adg uses the dataProviders defaults, or there are no columns at all.
"adg_test.mxml" has the AdvancedDataGrids/code.
"adg_test_renderer.mxml" is a renderer for one of the columns.
Would appreciate learning what I'm doing wrong.
Thanks for any help.

A Select statement with Appending table statement in it.

Hi,
How can I use a select statement with a <Appening table> statement in it.
SELECT DISTINCT <field Name>
                FROM <DB table name>
                APPENDING TABLE <itab>
                WHERE <fieldname> EQ <Itab1-fieldname>
                  AND <fieldname> EQ <itab2-fieldname>.
Can I use the above select statement.If I'm using this...how this works?
Regards
Dharmaraju

Hi, Dharma Raju Kondeti.
I found this in the SAP online help, hope this can help you.
Specifying Internal Tables
When you read several lines of a database table, you can place them in an internal table. To do this, use the following in the INTO clause:
SELECT ... INTO|APPENDING [CORRESPONDING FIELDS OF] TABLE <itab>
                          [PACKAGE SIZE <n>] ...
The same applies to the line type of <itab>, the way in which the data for a line of the database table are assigned to a table line, and the CORRESPONDING FIELDS addition as for flat work areas (see above).
The internal table is filled with all of the lines of the selection. When you use INTO, all existing lines in the table are deleted. When you use APPENDING; the new lines are added to the existing internal table <itab>. With APPENDING, the system adds the lines to the internal table appropriately for the table type. Fields in the internal table not affected by the selection are filled with initial values.
If you use the PACKAGE SIZE addition, the lines of the selection are not written into the internal table at once, but in packets. You can define packets of <n> lines that are written one after the other into the internal table. If you use INTO, each packet replaces the preceding one. If you use APPENDING, the packets are inserted one after the other. This is only possible in a loop that ends with ENDSELECT. Outside the SELECT loop, the contents of the internal table are undetermined. You must process the selected lines within the loop.

feng.

Help with TYPE and LIKE statements

HI guys,
I know this is really novice stuff, but I am a little confused.
Can anyone please explain the exact difference between TYPE and like with the help of a program, to understand it.
What situation would demand the use of each of the LIKE statement, since I can do all these things using the TYPE ?

Hi Akhil,
I summarized the info in SDN posts and SAP Help, to make it easier for you to understand. I also included some code snippets. Hope these prove to be helpful to you.
The following is from SAP Help:
The Additions TYPE and LIKE
The additions TYPE type and LIKE dobj are used in various ABAP statements. The additions can have various meanings, depending on the syntax and context.
·        Definition of local types in a program
·        Declaration of data objects
·        Dynamic creation of data objects
·        Specification of the type of formal parameters in subroutines
·        Specification of the type of formal parameters in methods
·        Specification of the type of field symbols
A known data type can be any of the following:
·        A predefined ABAP type to which you refer using the TYPE addition
·        An existing local data type in the program to which you refer using the TYPE addition
·        The data type of a local data object in the program to which you refer using the LIKE addition
·        A data type in the ABAP Dictionary to which you refer using the TYPE addition. To ensure compatibility with earlier releases, it is still possible to use the LIKE addition to refer to database tables and flat structures in the ABAP Dictionary. However, you should use the TYPE addition in new programs.
The LIKE addition takes its technical attributes from a visible data object. As a rule, you can use LIKE to refer to any object that has been declared using DATA or a similar statement, and is visible in the current context. The data object only has to have been declared. It is irrelevant whether the data object already exists in memory when you make the LIKE reference.
·        In principle, the local data objects in the same program are visible. As with local data types, there is a difference between local data objects in procedures and global data objects. Data objects defined in a procedure obscure other objects with the same name that are declared in the global declarations of the program.
·        You can also refer to the data objects of other visible ABAP programs. These might be, for example, the visible attributes of global classes in class pools. If a global class cl_lobal has a public instance attribute or static attribute attr, you can refer to it as follows in any ABAP program:
DATA dref TYPE REF TO cl_global.
DATA: f1 LIKE cl_global=>attr,
       f2 LIKE dref->attr.
You can access the technical properties of an instance attribute using the class name and a reference variable without first having to create an object. The properties of the attributes of a class are not instance-specific and belong to the static properties of the class.
Example
TYPES: BEGIN OF struct,
         number_1 TYPE i,
         number_2 TYPE p DECIMALS 2,
       END OF struct.
DATA: wa_struct TYPE struct,
       number    LIKE wa_struct-number_2,
       date      LIKE sy-datum,
       time      TYPE t,
       text      TYPE string,
       company   TYPE s_carr_id.
This example declares variables with reference to the internal type STRUCT in the program, a component of an existing data object wa_struct, the predefined data object SY-DATUM, the predefined ABAP type t and STRING, and the data element S_CARR_ID from the ABAP Dictionary.
The following info is from various posts:
--> Type: It is used when userdefined object link with SAP system data type.
Local types mask global types that have the same names. When typing the interface parameters or field symbols, a reference is also possible to generic types ANY, ANY TABLE,INDEX TABLE, TABLE or STANDARD TABLE, SORTED TABLE and HASHED TABLE.
--> Like: It is when data object link with the other data object.
--> TYPE, you assign datatype directly to the data object while declaring.
--> LIKE,you assign the datatype of another object to the declaring data object. The datatype is referenced indirectly.
you can refer to all visible data objects at the ABAP program's positon in question. Only the declaration of the data object must be known. In this case it is totally irrelevant whether the data object already exists physically in
memory during the LIKE reference. Local data objects mask global data objects that have the same name.
--> Type is a keyword used to refer to a data type whereas Like is a keyword used to copy the existing properties of already existing data object.
Types: var1(20) type c.
data: var2 type var1. ( type is used bcoz var1 is defined with TYPES and it
does not occupy any memory spce.
data: var3 like var2. ( like is used here bcoz var2 is defined with DATA
so it does occupy space in memory ).
data: material like mara-matnr. ( like is used here bcoz mara-matnr is stored in memory)
--> Type refers the existing data type
--> Like refers the existing data object
Please Reward Points if any of the above points are helpful to you.

How to use a select statement with chinese characters?

I am currently developing a java servlet<using tomcat 4.x> which allows me to use select statement to retrieve results from the Microsoft SQL Server 2000 database. I am using a simple form to get the parameter for querying. The main problem i'm facing is that there are chinese information in the SQL database, but i can't retrieve it through the sql statement with the chinese characters input<thru the form with the help of NJ STAR>in the WHERE condition. When i execute the statement, it returns me no results even though the rows are present in the database.
Does anyone have the solution to using chinese words in the WHERE clause of the select statement to retrieve results with columns which contains chinese characters? Please help me. Thanks everyone. :)
PS: when i cut and paste those characters in the sql database and paste onto java.. it is ??? in questionmarks.. but when i paste them into excel 2000.. its shown as chinese chars again..
please heelppp~~

Greetings,
PS: when i cut and paste those characters in thesql
database and paste onto java.. it is ??? in
questionmarks.. but when i paste them into excelThis is why the SELECT is not returning any results.
You need to set the character encoding set on your
statement and parameters for the characters to be
properly translated. Refer to the charsetName
parameter in the String class constructor in your API
docs and also to
$JDK_DOCS/guide/intl/encoding.doc.html in your JDK
documentation.
2000.. its shown as chinese chars again..Because Office programs are performing the same kind
of character translation with the appropriate MS APIs.
please heelppp~~Regards,
Tony "Vee Schade" Cookis it possible for you to show me some coding examples? i don't really understand what is to be done in order to set the char set and what does it really do.. tried reading up but still dun understand.. :(
pardon my shallow knowledge of java..
ok..
The thing is when i used an insert statement with chinese characters of GBK format hardcoded into the java servlet and then i use the insert statement to insert the chars into the database, it cannot be seen as a chinese word when i off the NJStar. and then it can be searched out with my current form of servlet.. below is my coding of the servlet..
note: i've set my html file to charset = GBK
//prototype of Search engine...
//workable for GBK input and output...

with the above servlet i created, i can search out the data in the database which i've inserted through the insert statement. I still can't search for things i've keyed into the database directly using NJStar..
thank you so much for helping.. really hope any one else who knows the answer to this will reply too... thank you all so much...

Fustrating problem with self-made 5-state button

Hey guys, just wondering if you could help me, i don't have
much knowledge with actionscript and i created my own 5 state
button using a movie clip and a little bit of actionscript by
following a tutorial online. (
http://www.sanctifiedstudios.com/advanced-five-state-buttons/)
Basically, when rolled over, the button slides out, and when
rolled off, the button slides back in. The problem is, while the
button is rolling back in, if you flick your mouse onto the button
again quickly, instead of restarting the roll-out animation, the
button just flickers quickly between the in position and the out
position.
You can see it for yourself here: www.everlightmusic.com <
hover your mouse over the buttons on the right, move your mouse
off, and then while its rolling back in, quickly move your mouse
back onto it.
The actionscript for the buttons is this:
quote:
this.onRollOver = function(){
this.gotoAndPlay(20);
this.onRollOut = function(){
this.gotoAndPlay(30);
this.onPress = function(){
this.gotoAndStop(29);
this.onRelease = function(){
this.gotoAndStop(29);
this.onReleaseOutside = function(){
this.gotoAndPlay(40);
this.onRelease = function(){
_parent.gotoAndPlay(31)
And here is a screenshot of the movie clip timeline:
Click
Any help with this would be greatly appreciated :)

yeah this is typical when using a timeline based button
action. two things you could do:
1) control the state change by using a variable to indicate
when the motion is complete (or not) like 'isOpen' - you'd need to
do this for each button in combination with a condition in the
handler that 'reads' the var and determines the course of action -
of course the next problem is that if you 'rollout' while the
motion is happening and the handler fires previous to the setting
of the var to it's 'new' state it won't close because the condition
would only be fired once - the only way around that would be to
include a loop that runs until the condition is satisfied.
2) much better than the above method (which would get messy
fast) is to simply use the 'tween' class to create you motions, you
can then 'open' or 'close' from what ever the current position of
the clip is at the moment the handler is fired. you've got your
code on the timeline of the 'button' MC (good job) so you could
change it to something like this:

Problems with explain plan and statement

Hi community,
I have migrated a j2ee application from DB2 to Oracle.
First some facts of our application and database instance:
We are using oracle version 10.2.0.3 and driver version 10.2.0.3. It runs with charset Unicode 3.0 UTF-8.
Our application is using Tomcat as web container and jboss as application server. We are only using prepared statements. So if I talk about statements I always mean prepared statements. Also our application is setting the defaultNChar property to true because every char and varchar field has been created as an nchar and nvarchar.
We have some jsp sites that contains lists with search forms. Everytime I enter a value to the form that returns a filled resultset, the lists are performing great. But everytime I enter a value that returns an empty resultset, the lists are 100 times slower. The jsp sites are running in the tomcat environment and submitting their statements directly to the database. The connections are pooled by dbcp. So what can cause this behaviour??
To anaylze this problem I started logging all statements and filled-in search field values and combinations that are executed by the lists described above. I also developed a standalone helper tool that reads the logged statements, executes them to the database and generates an explain plan for every statement. But now there appears a strange situation. Every statement, that performs really fast within our application, is now executed by the helper tool extremely slow. So I edited some jsp pages within our application to force an explain plan from there (tomcat env). So when I'm executing the same statement I'm getting with the exactly same code two completely different explain plans.
First the statement itself:
select LINVIN.BBASE , INVINNUM , INVINNUMALT , LINVIN.LSUPPLIERNUM , LSUPPLIERNUMEXT , LINVIN.COMPANYCODE , ACCOUNT , INVINTXT , INVINSTS , INVINTYP , INVINDAT , RECEIPTDAT , POSTED , POSTINGDATE , CHECKCOSTCENTER , WORKFLOWIDEXT , INVINREFERENCE , RESPONSIBLEPERS , INVINSUM_V , INVINSUMGROSS_V , VOUCHERNUM , HASPOSITIONS , PROCESSINSTANCEID , FCURISO_V , LSUPPLIER.AADDRLINE1 from LINVIN, LSUPPLIER where LINVIN.BBASE = LSUPPLIER.BBASE and LINVIN.LSUPPLIERNUM = LSUPPLIER.LSUPPLIERNUM and LINVIN.BBASE = ? order by LINVIN.BBASE, INVINDAT DESC
Now the explain plan from our application:
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time |
| 0 | SELECT STATEMENT | | 101 | 28583 | 55 (0)| 00:00:01 |
| 1 | NESTED LOOPS | | 101 | 28583 | 55 (0)| 00:00:01 |
| 2 | TABLE ACCESS BY INDEX ROWID| LINVIN | 93709 | 12M| 25 (0)| 00:00:01 |
|* 3 | INDEX RANGE SCAN | LINV_INVDAT | 101 | | 1 (0)| 00:00:01 |
| 4 | TABLE ACCESS BY INDEX ROWID| LSUPPLIER | 1 | 148 | 1 (0)| 00:00:01 |
|* 5 | INDEX UNIQUE SCAN | PK_177597 | 1 | | 1 (0)| 00:00:01 |
Predicate Information (identified by operation id):
3 - access("LINVIN"."BBASE"=:1)
filter("LINVIN"."BBASE"=:1)
5 - access("LSUPPLIER"."BBASE"=:1 AND "LINVIN"."LSUPPLIERNUM"="LSUPPLIER"."LSUPPLIERNUM")
Now the one from the standalone tool:
| Id | Operation | Name | Rows | Bytes |TempSpc| Cost (%CPU)| Time |
| 0 | SELECT STATEMENT | | 93773 | 25M| | 12898 (1)| 00:02:35 |
| 1 | SORT ORDER BY | | 93773 | 25M| 61M| 12898 (1)| 00:02:35 |
|* 2 | HASH JOIN | | 93773 | 25M| 2592K| 7185 (1)| 00:01:27 |
| 3 | TABLE ACCESS BY INDEX ROWID| LSUPPLIER | 16540 | 2390K| | 332 (0)| 00:00:04 |
|* 4 | INDEX RANGE SCAN | LSUPPLIER_HAS_BASE_FK | 16540 | | | 11 (0)| 00:00:01 |
| 5 | TABLE ACCESS BY INDEX ROWID| LINVIN | 93709 | 12M| | 6073 (1)| 00:01:13 |
|* 6 | INDEX RANGE SCAN | LINVOICE_BMDT_FK | 93709 | | | 84 (2)| 00:00:02 |
Predicate Information (identified by operation id):
2 - access("LINVIN"."BBASE"="LSUPPLIER"."BBASE" AND "LINVIN"."LSUPPLIERNUM"="LSUPPLIER"."LSUPPLIERNUM")
4 - access("LSUPPLIER"."BBASE"=:1)
6 - access("LINVIN"."BBASE"=:1)
The size of the tables are: LINVIN - 383.692 Rows, LSUPPLIER - 115.782 Rows
As you can see the one executed from our application is much faster than the one from the helper tool. So why picks oracle a completely different explain plan for the same statement? An why is a hash join much slower than a nested loop? Because If I'm right a nested loop should only be used when the tables are pretty small..
I also tried to play with some parameters:
I set optimizer_index_caching to 100 and optimizer_index_cost_adj to 30. I also changed optimizer_mode to FIRST_ROWS_100.
I would really appreciated, if somebody can help me with this issue, because I'm really getting more and more distressed...
Thanks in advance,
Tobias

Hi again,
Here ist the answer:
The problem, because I got two different explain plans, was that the external tool uses the NLS sesssion parameters coming from the OS which are in my case "de/DE".
Within our application these parameters are changed to "en/US"!! So if I'm calling in my external tool the java function Locale.setDefault(new Locale("en","US")) before connecting to the database the explain plans are finally equal.That might explain why you got two different execution plan, because one plan was obviously able to avoid a SORT ORDER BY operation, whereas the second plan required to run SORT ORDER BY operation, obviously because of the different NLS_SORT settings. An index by default uses the NLS_SORT = 'binary' order whereas ORDER BY obeys the NLS_SORT setting, which probably was set to 'GERMAN' in your "external tool" case. You can check the "NLS_SESSION_PARAMETERS" view to check your current NLS_SORT setting.
For more information regarding this issue, see my blog note I've written about this some time ago:
http://oracle-randolf.blogspot.com/2008/09/getting-first-rows-of-large-sorted.html
Now let me make a guess why you observe the behaviour that it takes so long if your result set is empty:
The plan avoiding the SORT ORDER BY is able to return the first rows of the result set very quickly, but could take quite a while until all rows are processed, since it requires potentially a lot of iterations of the loop until everything has been processed. Your front end probably by default only display the first n rows of the result set and therefore works fine with this execution plan.
Now if the result set is empty, depending on your data, indexes and search criteria, Oracle has to work through all the data using the inefficient NESTED LOOP approach only to find out that no data has been found, and since your application attempts to fetch the first n records, but no records will be found, it has to wait until all data has been processed.
You can try to reproduce this by deliberately fetching all records of a query that returns data and that uses the NESTED LOOP approach... It probably takes as long as in the case when no records are found.
Note that you seem to use bind variables and 10g, therefore you might be interested that due to the "bind variable peeking" functionality you might potentially end up with "unstable" plans depending on the values "peeked" when the statement is parsed.
For more information, see this comprehensive description of the issue:
http://www.pythian.com/blogs/867/stabilize-oracle-10gs-bind-peeking-behaviour-by-cutting-histograms
Note that this changes in 11g with the introduction of the "Adaptive Cursor Sharing".

Could not find prepared statement with handle %.

Greetings. I've seen several posts for this error on the web, but no clear cut answers. I captured the code below in profiler, with the intention of replaying in mgmt studio.
However, the attempt end in the following error: "Could not find prepared statement with handle 612."
declare @p1 int
set @p1=612
declare @p2 int
set @p2=0
declare @p7 int
set @p7=0
exec sp_cursorprepexec @p1 output,@p2 output,N'@P0 int,@P1 int,@P2 int,@P3 int,@P4 bit',N'EXEC dbo.mySproc @P0,@P1,@P2,@P3,@P4 ',4112,8193,@p7 output,219717,95,NULL,1,0
select @p1, @p2, @p7
Something noteworthy is that my sproc only has 5 input parameters, but this makes it look like it has many more.
How do I manipulate the code enough to make it work in mgmt studio? Thanks!
TIA, ChrisRDBA

In profiler you would normally see RPC:Starting and RPC:Completed. The statement shown in RPC staring is what you need to pick because as Erland explained, completed would show "funky" behavior.

Set Session State with Shuttle items

Is it possible to have session state set with each item selected in a shuttle? You have a shuttle with 4 possible options, you select item 2 from the left portion of shuttle and it is moved to the right.. Can you set the session state at that point?
What I am trying to do is take the session state after change in the control and use it to populate a text field below. The returned values are used in a sql select to populate the text box with a looked up value...
Thank you,
Tony Miller

Won't this just push the last items value in, as apposed to appending the value?
Tony,
No. Because for shuttle items the return value is stored as colon delimited string.
Means after each change you will have a colon delimited string in the session state with selected values(moved to right).

Java Switch Statement with Strings

Apparently you cant make a switch statement with strings in java. What is the most efficient way to rewrite this code to make it function similar to a swtich statement with strings?
switch (type){
               case "pounds":
                    type = "weight";
                    break;
               case "ounces":
                    type = "weight";
                    break;
               case "grams":
                    type = "weight";
                    break;
               case "fluid ounces":
                    type = "liquid";
                    break;
               case "liters":
                    type = "liquid";
                    break;
               case "gallons":
                    type = "liquid";
                    break;
               case "cups":
                    type = "liquid";
                    break;
               case "teaspoons":
                    type = "liquid";
                    break;
               case "tablespoons":
                    type = "liquid";
                    break;
          }

I'd create a Map somewhere with entries "liquid", "weight", etc.
public class Converter {
    private static Map<String, List<String>> unitMap = new HashMap<String, List<String>>();
    private static String[] LIQUID_UNITS = { "pints", "gallons", "quarts", "millilitres" };
    private static String[] WEIGHT_UNITS = { "pounds", "ounces", "grams" };
    static {
        List<String> liquidUnits = new ArrayList<String>();
        for (int i = 0; i < LIQUID_UNITS.length; i++) liquidUnits.add(LIQUID_UNITS));
unitMap.put("liquid", liquidUnits);
... // other unit types here
public String findUnitType(String unit) {
for (String unitType : unitMap.keySet()) {
List<String> unitList = unitMap.get(unitType);
if (unitList.contains(unit))
return unitType;
return null;
It might not be more "efficient", but it's certainly quite readable, and supports adding new units quite easily. And it's a lot shorter than the series of if/else-ifs that you would have to do otherwise. You'll probably want to include a distinction between imperial/metric units, but maybe you don't need it.
