Where the $%^&* are the standard Java classes?

I've loaded and run j2sdk-1_4_2_01-windows-i586.exe (I use Win 98).
Then I tried to write my first applet, which began:
import java.awt.Graphics;
import java.awt.Font;
import java.awt.Color;
But the compiler said it could not find the Color class.
So I looked in the installation directory and its various subdirectories and could not find Color.java or Color.class (or rather Wondows Explorer could not find them for me).
So where the $%^&* are they supposed to be?
If necessary how do I get them installed in the right place?

Thanks for your initial responses, everyone. Here's the additional info some of you requested.
I installed the SDK in directory C:\j2sdk1.4.2 in case I ever want to experiment with another version.
I have not modified any MS-DOS environment variables - as far as I'm concerned this is the installer's responsibility and every other product I've ever installed has handled this - sound cards, CD readers, software, whatever.
Directory C:\j2sdk1.4.2 contains file src.zip and WinZip (6.3, so AFAIK it handles long file names OK) tells me src.zip contains a vast collection of files - some look relevant to my current requirements (e.g. those with path java\applet and java\awt) and others not so relevent to my requirements.
abramia is right, I used the Gel IDE (http://www.gexperts.com/). I've set the project properties as follows in Gel:
Libraries:
* Basic Java libraries
Source paths:
* Where I keep my own source code - no problem, javac is finding the applet code OK.
* C:\j2sdk1.4.2 (where I installed the SDK).
Command line generated by the "compile" menu option - too long to copy & paste!
Output path: I'll worry about this when I get a clean compile. I used the same procedure as when I set the 1st source path, so I don't expect problems.
So can anyone help me now with this additional info? Or is there any other info I need to supply?

Where can I download the api's of java classes ?

I'd like to download all the api's of java classes. I only found a lot of pages, but i don't like to download one after other for a very long time.
Where I can find a complete document of java classes api in a single document?
When I say api of java classes I mean the name of all java classes , it's methods, atributes, what the class does, and so on...
For the JAVA 1.5.0 of course...
Thanks.

Deploying the JSPs, Servlets and Java class files

Hello All,
I'm very new to the Oracle 9i AS. We are using Version 1.0.2.2.
How do we deploy the JSPs, Servlets, and Java class files (simple class files, not EJBs)?
plese give us the procedure and stpes how to deply or the links for the same.
Thanks,
Santhosh.

Hi
I guess u r running apache-jserv as servlet engine for your jsp and servlets. If its so, jsp files can be run without any additonal configuration by putting the jsp file under document root or any subdirectory and for running servlets u have to add classpath entries for your servlet in jserv.properties file.
To make sure that your servlet engine is working, try
http://servername:port/servlet/IsItWorking, if u get success msg that means servlet engine is working fine.
Hope this will help

How to execute the ldapsearch command by java class in linux os?

hi,all
I want to query the users by ldapsearch command. I call the command in my java class. In windows, It work well. But in linux , there haven't any result. My test program is following:
===============
import java.util.*;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.LineNumberReader;

String line;
while ((line = input.readLine ()) != null){
System.out.println("Line:"+line);
if(line.startsWith("uid")){
String temp=line.substring(line.indexOf(":")+1,line.length());

Standard Java class communicating with a servlet

Hey,
I am trying to access a standard java classes member via a servlet class however the data is never received even though the member is visible on compilation. is there something Im doing wrong ?
public class Start {
//lots of stuff
     static List<Plug> plugList = Collections.synchronizedList(new LinkedList<Plug>());
//lots more stuff
public class wah extends HttpServlet{
        public void doGet( HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException{
                doPost(request, response);
    public void doPost(HttpServletRequest request,
                                HttpServletResponse res)throws ServletException, IOException{
                res.setContentType("text/html");
                PrintWriter out = res.getWriter();
                out.println("wahwahwah");
                synchronized(Start.plugList){
                        out.println("pluglist");
                        Iterator i1 = Start.plugList.iterator();
                        while (i1.hasNext()) {
                                Plug oldPlug = (Plug)i1.next();
                                out.println("PLug : " + oldPlug.getaddress64());
        }//doPost
}

Don't post all your code. Instead, make a simplified version of the code that demonstrates what your problem is and that we could compile and see what is going on. Make it as simple as possible but still demonstrating the problem.
Who knows, when you make the SSCCP (small, self contained, compileable program) you will find your mistake as well.
But without seeing any code all I can say is that the date you are accessing in the list has not been made available when you try to get it from the servlet. Perhaps the servlet call is blocking the other threads from accessing the list to put data into it, perhaps the other threads haven't begun working yet, perhaps the list you give to the servlet isn't the same list (but instead a copy of the list) that the data is being entered into, or many other reasons.
One thing I would assume you need to do, since the Servlet is the data consumer, you need to make sure the data has been entered before the servlet tries to read it. The best way to do that is to put a wait() in the servlet code so that it knows it can't do anything until the producers are finished. Then the producers would add a notify() to tell the servlet to go ahead and display the data.
So some modification might be:
public class Start {
//lots of stuff
     static List<Plug> plugList = Collections.synchronizedList(new LinkedList<Plug>());
        //marker to let servlet know that it can consume data
        private static boolean done = false;
        //producers call this method when list is ready for use
        static void setReadyToConsume() { done = true; }
        //servlet calls this to check if the list is ready
        public static boolean isReadyToConsume() { return done; }
//lots more stuff
    public void doPost(HttpServletRequest request,
                                HttpServletResponse res)throws ServletException, IOException{
                res.setContentType("text/html");
                PrintWriter out = res.getWriter();
                out.println("wahwahwah");
                synchronized(Start.plugList){
                       //Hold off trying to use list until list is ready
                        while (!Start.isReadyToConsume()) {
                              try {
                                      Start.plugList.wait();
                              } catch (InterruptedException ie) {
                                      log("Waiting for Plugs to be ready interrupted. Continuing to wait.");
                                      log(ie.getMessage(), ie);
                        out.println("pluglist");
                        Iterator i1 = Start.plugList.iterator();
                        while (i1.hasNext()) {
                                Plug oldPlug = (Plug)i1.next();
                                out.println("PLug : " + oldPlug.getaddress64());
        }//doPostAnd don't forget to add a Start.plugList.notify() or Start.plugList().notifyAll() in the producer code after it calls the setReadyToConsume() method.

Customize Standard Java Class

Hi,
I need to customize a standard java class. I decomplied the source code of the class file, make the changes as required, and then compile it and upload it to the original path.
The problem is that I am receiving java exception NoSuchMethod error after customizing. Even though I revert it to the original one, I am receiving the same error. I did re-bounce the HTTP server.
The class is $JAVA_TOP/oracle/apps/po/communicate/POGenerateDocument.class
Am I missed any important steps?
Thanks in advance!

I would like to know how UI Hints work and how UI Maps are generated based on UI Hints.
Are there any java classes behind?

Can someone help me on how to do this?

How can I either move or view the source of a JAVA CLASS user object?

I am using Oracle 8i and I have the following JAVA CLASS objects in my database. I need to move some of these objects to a different database.
1) How can I do this?
2) How can I view the JAVA source code since these are classes?
My knowledge of Oracle is limited. I have searched and searched and I can't find the answer. Any help would be greatly appreciated

The source far java class objects that are not derived from java source objects
(which is the case here, and is typically the case, such as when one loads
classes into the database using loadjava on a jar that contains only .class
files) does not exist in the database (just as it does not exist in a jar which
contains only .class files). So there is essentially no way to view the source, short of extracting the bytecodes and using some decompiling tool. I don't recall what methodologies exist for extracting bytecodes in 8i. As for transferring
the classes to another database, the standard Oracle import/export tool can do this.

How to set the classpath and path from the jsp to call java class function

Hi Exprets,
I have a requirement to call a java class function which returns a hashmap object from the jsp. The java class in present in one jar file and that jar file is location somewhere in unix path. So the requirement is to set the classpath for that jar file and then create the object of the java class and then call the function.
If any one know how to achieve it, please reply as soon as possible.
thanks in advance,

It is never advisable to store large data sets in the session. But it will depend on a lot of factors:
1. How costly is the query retrieving the data from the database?
If it's a complex query with lots of joins and stuff, then it will be better to store it in the session as processing the query each time will take a lot of time and will decrease performance. On the other hand if the query is simple then it's advisable not to store it in the session, and fetch it each time.
2. Are there chances for the data to become stale within a session?
In this case storing the data is session will mean holding the stale data till the user session lasts which is not right.
3. How many data sets does the session already holds?
If there are large no. of data sets already present in the session, then it's strictly not advisable to store the data in the session.
4. Does the server employ some kind of caching mechanism?
Using session cache can definitely improve performance.
You will have to figure out, what is the best way analyzing all the factors and which would be best in the situation. As per my knowledge, session is the only place where session specific data can be stored.
Also, another thing, if the data set retrieved is some kind of data to be displayed in reports, then it would be better to use a pagination query, which will retrieve only the specific no. of rows at a time. A navigation provided in the UI will retrieve the next/previous data set to display.
Thanks,
Shakti

Where are C++ Standard Library Classes for Unicode RFC SDK?

I have the Unicode RFC SDK and there is a document (sapucdoc.htm) that explains that the C++ standard library classes have SAP_ equivalents. For example:
string --> SAP_string
It then says that header files for these classes are named SAP<standard lib name>.hpp. So for the string class:
string.h --> SAPstring.hpp
The rfcsdk/include directory does not contain any of the header files. Where can I find these header files and possibly libraries I need to use the standard C++ libraries with this version of the RFC SDK?
Thanks.

Those icons are not accessible directly.
Try setting the appropriate button type, like following code uses "info light" type to show the "i" icon.

Thanks in advanceI wonder how that would work then. Let's take a fictive example. You have a class com.mycompany.myapp.Foo. This would mean that the class is stored in some directory like this:
c:/webrootdir/myapp/WEB-INF/classes/com/mycompany/myapp/Foo.classTo be able to run such a class from the commandline using Java, you would have to invoke this command:
java -cp c:/webrootdir/myapp/WEB-INF/classes com.mycompany.myapp.FooHow would knowing the exact path to this class help you?

Where exactly are the media files kept now?

It used to be simple, the media files were all in the Final Cut Events folders and if you trashed them they were gone.
However, now that I have updated my 10.0.9 projects and events to 10.1, I apparently have identical media files in the "Old Final Cut Projects and Events" folder together with the new Library.
I believe that some of these are symbolic, but which ones?
If I delete something from the "Old Final Cut Projects and Events" folder, will it still be present in the new Library . . . . . and vice versa?
What if I delete both lots?
Where exactly are my old media files?

It's a tricky bit of engineering. If you updated the projects and events and the media was already in the events then the media will appear to be in both plays simultaneously, but only taking the drive space of one. If you delete the old events, the drive space will not go down because the media is still on the hard drive.
Here's the thing, when we say a media file is in a folder, it's not physically in the folder. It's somewhere on your hard drive, wherever there was space when the file was written to the drive. The file structure says they're in a folder or move from folder to folder, but in reality they never move. Only the directory structure changes. That's what's happening here. Both folders, old events, new libraries are pointing to same space on your physical hard drive where the media files are living. Both are holding the media files in their directory. If you delete them both the media will disappear from the directories and that drive space will be freed and eventually get physically overwritten as more stuff is written on the drive.

Displaying the output from a java class executed from W/I another class

I have compiled a java class, but I have run into a problem executing the class. I have read the posts and still have not solved the solution. I have tried to get the output of the Process by using "proc.getOutputStream().toString()", however it displays it in binary (ex. java.io.BufferOutputStream@48eb2067). If anyone can provide any assistance I would greatly appreciate it. Or if you could tell me if I'm on the right track or not. Thanks ALL. Here is a code segment:
int truncStart = s.indexOf(".java");
               s = s.substring(0,truncStart);
               String[] command2 = {"java","c:/"+s};
               try
               //JOptionPane.showMessageDialog(null,"Exec. File "+s, "Exec. File : ",JOptionPane.ERROR_MESSAGE);
               proc = Runtime.getRuntime().exec(command2);
               JOptionPane.showMessageDialog(null,"Output: "+proc.getOutputStream().toString(),"Output"
,JOptionPane.ERROR_MESSAGE);
               }

You have to read the stream, like:
InputStream stream = proc.getOutputStream();
// now use methods on stream, such as read() to read the characters/lines - or wrap it in another line-friendly stream - see the java.io.* classes - keep reading until you get an end-of-stream indicator, depending on the API you end up using.

After upgrade to JHS Production: cannot find two standard java Classes

Hi, First: congratulations on the Production release. Great that it is there.
After making several backups, I have upgraded to JHS build 91 Production release (I came from JHS build 78).
1. after upgrade to JHS Production, I tested my application first (so before re-enabling Jheadstart on the ViewController and regenerating pages). The application still worked fine
2. I re-enabled JHeadstart on the VC project
3. I opened my Applictation Definition Files and saved them (I noticed a deprecated property OverwriteUiModel that disappeared after saving)
4. I ran the generator on my three App. Def. Files.
5. I rebuild the whole application
6. I ran the application, the first (Table-style) page comes up fine
7. But when clicking on one of the records in the Table to navigate to the Form page...the Embedded OC4J exits with a fatal error:
Fatal error: Cannot find class java/lang/StackOverflowError
Fatal error: Cannot find class java/lang/NullPointerException
The last part of the log before these fatal errors is as follows:

Any idea why this might have happened, just because I upgrade to JHS production release?
I am reverting to build 78 again to continue developing, but hope to be able to get working with the prod release soon, but I lack knowledge to determine where the error occurs...

Sandra,
I have the (ugly) feeling that I am facing the problem mentioned in http://forums.oracle.com/forums/thread.jspa?messageID=1211326? : it looks like when a JSPX page gets too complex, the Embedded OC4J raises this StackOverFlow class notfound error :-(. Probably the (it only hits me when navigating to the most complex page) generated page generated with build 78 was fine, but the generated page after build 91 has become too complex, allthough nothing changed in between. What I can see from the difference between the before and after build 91 situation for all pages, is that you have added the <id=...> arguments to all ADF elements, like [id="PersonsSaveButton"] in:
<af:commandButton actionListener="#{bindings.Commit.execute}"
                  action="Commit"
                  textAndAccessKey="#{nls['SAVE_BUTTON_LABEL_PERSONS']}"
                  id="PersonsSaveButton">
               <af:resetActionListener/>
</af:commandButton>In build78 these were not there. As far as I can see another difference after generating with build 91 is a new element in the page:
<af:panelGroup rendered="#{(bindings.PersonsIterator.currentRowIndexInRange!=-1 and bindings.PersonsIterator.findMode!='true')}">I have not seen a proper solution for this on the JDeveloper forum. I noticed people asking if there is a kind of 'maximum' on how complex a page can get before this error situation happens. No answer on that found (you do not want to know there is a maximum anyway).
The specific page is a master with 5 stacked detail regions and three "use as LOV" groups. Further on about 30 domains are used...
And the page has not finished yet, it will get more "complex" that this. I hope someone knows a good solution so that I can continue to use the Embedded OC4J for testing, otherwise developing wil get very time consuming if I have to deploy to AS every time...something I cannot afford since the project deadline is getting nearer and nearer.

Java Program in MDM to call a standard java class

Hi All,
In MDM- GDS, (Global Data Synchronization), we have a scenario where, once we register the Items , it will be transported to a Data Pool called 1SYNC through SAP PI.
There is a standard Java PRoxy(Kind of java Class) in MDM, which will be triggered once we register the Item in MDM-GDS.
That Java Proxy will send the Item INfo as a XML message to PI.
So we would like to know whether its possible to automate this process.
Like,Writing a new Java Program which will check all the new items and trigger the Java Proxy and send these items as XML Messages to PI.
I m new to MDM. So it would be really helpful, If i could get some inputs on this. Like, is it possible in MDM. If so, how?

Aarthi,
you can acheive this from MDM itself, and need not to write any Java proxy.
you may consider following logic.
Create a field with the Name Status and Initilize it with Value "new". Now define syndicaiton Map to syndicate records which holds value "new" in the status field. define a workflow with syndication step, using maps defined earlier. After syndication step, execute an assignment to change Status field value from "New" to "Syndicated".
Revert back if any question.
