The API documentation has a link at the top of every page that says "Index". If you follow that and look for toFront(), you will find it exists in java.awt.Window and javax.swing.JInternalFrame.
To use it in a Java application, create an object x of either of those two classes and write "x.toFront();".

it gives error message... how can � use struct model in java applets???
if you help me i will be greatfull....

� use import but it doesn't work.
i add: import renk; or import class renk;
how will � add import I assumed based on your initial post that the renk and benek classes were in the same file. Apparently you're saying they are not. So for another thing, make your renk class "public class renk", and add the "public" keyword to the 3 members of that class. Then if your code still doesn't see the "renk" class, it would just be that you don't have the directory that contains the compiled "renk.class" in your classpath.

Where I can find documentations on how to use MyComponse API ?

Where I can find documentation on how to use MyComponse API ?
Any example ?
Thanks

not 100% sure at which point the callout to BEFOREPROCESSCOMPOSE is done, but during the process logs phase, the data in the CVR$ tables is copied into the clg$ tables, and the cvr$ table dml flags cleared
unles the query is very complex/long running why not join the clg$ tables (only have the data that has changed, so smaller than the cvr$ tables, to your base tables for determining if relevant within the MyCompose needCompose method?
an example from one of our MyCompose classes is
public int needCompose(Connection conn, String clientid) throws Throwable{
boolean baseDirty = false;
Statement st = conn.createStatement();
String sql = null;
int rowCount = 0;
int fetchCount = 0;
ResultSet rows;
// log user
// sql = "INSERT INTO qpub_log (TIMESTMP,message) "
// + " values (sysdate, '" + clientid + " assd' )";
// rowCount += st.executeUpdate(sql);
// need to compose if there are any relevant changes to assessment details FOR
// TIR / SOLO assessments
// Inspection history checklists
// PIJ marking sheets
// INSSI
// Risk Assessment)
// also changes to (in case of underlying alterations causing data to be withdrawn)
// STATUS_LOGS
// ROLE_ASSGNTS
if(this.baseTableDirty("CDB_OWNER", "ASSESSMENT_DETAILS")){
return oracle.lite.sync.MyCompose.YES;
if(this.baseTableDirty("CDB_OWNER", "STATUS_LOGS")){
sql = "SELECT count(clg.context_key) "

rows = st.executeQuery(sql);
rows.next();

How to use Thread.sleep() with Java Berkeley Base API?

Hi,
I have explained the weird problem about the server was too busy to response to SSH but it continued to finish to run (Server not response when inserting millions of records using Java Base API
Even I tried to increase CachSize and renice Java program, but it did not work. So, I am thinking to set sleeping time for threads in Java Berkeley Base API (using “ps” command, there were 18 light weight processes created). My program did not implement transaction or concurrency because it simply creates (millions) databases records only. Is it possible and correct to do like this in the code:
try{
//do create a db record
Thread.currentThread().sleep(1000);//sleep for 1000 ms
catch(ItrerruptedException ie){
Thank you for your kindly suggestion.

where can I get the help doc about use AT commands in java.
Can you give me some code example about this. It is
difficulty to me to write it myself.You simply have to send the characters and receive the characters via the comm extension. Here is the ITU standard command set - http://ridge.trideja.com/wireless/atcommands/v250.pdf. Various modems and other devices extend this in a number of ways, you may need to find documentation specific to your device as well. But start with the standard.

How to view excel spreadsheet in java

Hello
Is there a way to open an excel spreadsheet in java? I don't mean reading and writing from an excel file, but instead embedding excel in java. For example instead of launching excel using the Desktop class and opening a new excel window, Java would open an instance of excel and add it to Jframe or Jpanel. Sort of like what Eclipse does when you Open a file with In_Place Editor. Google returns results on how to use some windows dll file and using active x control or whatnot.. Was wondering if there is a better and simpler way..
Thank you.

My first try with "embed excel in Java" returned as the first link a page from a company named JIntegra for which this seems to be their main business. Here's the link I found, just for information:

How to use custom API's

Hi All,
In OIM how can i use my own/Custom API"S. Wher do i need to place the Jar/Class files. Like in other Identity Management tools (I only have the experience of SUN) you can place the files under WEB-INF/lib or WEB-INF/classes and then can easily use them, does OIM provides this/similar kind of functionality and how we can use that.

Hi,
If you want to use custom API to create adapter then put the jar file in <OIM_Install>/xellerate/Java Task/
folder and if you want to use them to create task Schedular then put it in <OIM_Install>/xellerate/Schedular/

How to Use Exec function in Java Code

How to Use Exec method
I want to Execute command
net Start "some service"
using exec method of runtime class
or i use some other way if suggest

Assuming you have read http://java.sun.com/j2se/1.4.2/docs/api/java/lang/Runtime.html#exec(java.lang.String) already, I can only suggest to be more specific in what your problems are. If you are after just some example code, then download ftp://ftp.ebi.ac.uk/pub/software/textmining/monq/monq.tar.gz and have a look at the source code of monq.stuff.Exec. It does all those things which are necessary to keep track of a Process after it was created with exec.
