Retrieve all class in a package

Hi,
Is there a method to retrieve all name of the class in a package, to recreate the tree of the class use in my prog
I can just retrieve all the packages with Package.getPackages() and a sorting function.
the Next step is :
Package package = Package.getPackage("test");
Class[] classTab = ...;or
String[] StrClassNameTab = ...;I can't use directory where the class is, because the jar or the directory doesn't exist (i must provide an ".exe" with JBuilder)

Short of parsing the classpath, there is no built in way to do this.
I'm not sure what you mean with an exe and JBuilder, but walking the directories in the classpath is going to be the way to do this (it's how the JVM does it, after all). If the classes are in a JAR (or multiple JARs), then you'll have to walk those as well.

How to discover all names of class of a package

Hello!
Ineed to developer a class that discover all class name and all method name of a package and put it into a database.
Anyone have an Idea how to make this?
Thanks for help-me.

Sure. Given a source or classes directory, go to the directory indicated by the package name. Get all the files in the directory (*.java or *.class depending), using a File object. You may also need a FilenameFilter. BTW, the source file method would not catch multiple classes in one file, while the class file method would.

JAVABEAN ,is it all class need to collect together by package?

hello,
i want to know . all class stored in the class (C:\Tomcat_5.0\webapps\BB2004\WEB-INF\class\)in tomcat.
is it must need to create folder to store all class. and package them in the folder.
class A call the class B in the class A statement.
class B , class A are stored in the same package.
but class A cannot compile.
how???
in additional,
in the jsp,
if package name is test, so the class in following is it
<jsp:useBean id="user1" scope="page" class="test.user"/>

Class files get stored under the WEB-INF/classes folder, using the standard java layout.
ie if class A is in package myPackage, then A.class should be in WEB-INF/classes/myPackage/A.class
note that it is WEB-INF/classes, not WEB-INF/class
Your useBean statement looks correct. Yes, you must specify the full classname of any bean you use (ie including package identifier)
hope this helps

Retrieving ALL values from a single restricted user property

How can I retrieve ALL values of a single restricted user property from within
a .jpf file?
I want to display a dropdown list within a form in a JSP which should contain
all the locations listed in the property 'locations'. I ever get just the default
value when I access the property via
ProfileWrapper pw = userprofile.getProfileForUser(user);
Object prop = pw.getProperty("ClockSetup", "Locations");

Well, the code you've got will retrieve the single value of the property
for the current user. You're getting the default value because the
current user doesn't have Locations property set, so the ProfileWrapper
returns the default value from the property set.
I assume you want to get the list of available values that you entered
into the .usr file in Workshop. If so, I've attached a
SetColorController.jpf, index.jsp, and GeneralInfo.usr (put in
META-INF/data/userprofiles) I wrote for an example that does just this.
It uses the PropertySetManagerControl to retrieve the restricted values
for a property, and the jsp uses data-binding to create a list from that
pageflow method.
For a just-jsps solution, you can also use the
<ps:getRestrictedPropertyValues/> tag. I've attached a setcolor-tags.jsp
that does the same thing.

How do I find classes in a package

Hi,
I am working on an automation tool which is to be used for testing public API's in our product. The tool is supposed to work this way:
1. A developer of the API adds a new java file containing the test code for the API in a particular package (which the tool defines). Then he compiles and places the stuff in a jar. There is also a driver class in this same package path defined by the test tool. E.g.
driver class: com.aaa.bbb.DriverClass
new API test file: com.aaa.bbb.TestFile
Now the driver file's job is to find out all the other classes in this particular package and then do some processing. When I tried doing the getPackage() on this driver class to find out about the package I got back a null.
Question 1: How can I get the package for a particular class (An ugly way to do this would be to strip it out from the classname)
Question 2: How can I find out what other classes are there in a package?
Thanks in advance on this.

hai
i have the same problem to finding the classes in package...
in my case i know the jars name and i have loaded
classes using code
ResourceBundle bundle = ResourceBundle.getBundle("source\\ClasssPath");
StringTokenizer stToke = new StringTokenizer(bundle.getString("ClassPath"),";");
String temp;
ClassLoader classLoader = ClassLoader.getSystemClassLoader();
while(stToke.hasMoreTokens())
     temp = stToke.nextToken().trim();
if(temp.endsWith(".jar"))
JarFile jar = new JarFile(new File(temp));
     Enumeration en = jar.entries();
     String pathStr;
     while(en.hasMoreElements())
     pathStr = en.nextElement().toString();
     System.out.println("pathStr ="+pathStr);
     if(pathStr.endsWith(".class"))
          System.out.println( classLoader.getResource(pathStr));
          System.out.println(classLoader.loadClass(pathStr.substring(0,pathStr.indexOf(".class")).replace('/','.').trim()));
     else classLoader.loadClass(temp);
here i am getting the classes in that package using code
     String[] filLis = new File("//it//sella//converter//ptlf//startup//").list();
     int length = filLis.length;
     while(length-- >0)
     System.out.println(">"+filLis[length]);
but its returnign the class when this classes in locale folder(i.e)its not getting the classes in loaded memory...
so how to retrieve the class files names using package structure name...
(i am having more then 20 jars files, inthat inside the jar samepackage structue may appear in more then one jars )
pls help me in this field..
Thanx

Retrieving all values from hashmap in order you put them in

Hi guys,
I want to retrieve all values from a HashMap in the order I put them in.
So I can't use the values() method that gives back a collection and iterate over that.
Do you guys know a good way to do that ?

You can just do something like this:
class OrderedMap
    private final Map m_rep = new HashMap();
    private final List m_keys = new ArrayList();
    public Object get( final Object key )
        return m_rep.get( key );
    public Object put( final Object key, final Object value )
        final Object result = m_rep.put( key, value );
        if ( result != null )
            m_keys.add( key );
        return result;
    public Object remove( final Object key )
        final Object result = m_rep.remove( key );
        if ( result != null )
            m_keys.add( key );
        return result;
    public Iterator keyIterator()
        return m_rep.iterator();
}Then use it like this:
   for ( Iterator it = map.keyIterator(); it.hasNext(); )
       final Object value = map.get( it.next() );
   }This will be in the order you put them in. However, if you want to do this correctly, you should implement the Map interface and add all the methods. Another thing you can do is download the JDK 1.4 source, learn how they did and do it the same way for 1.2.

Hi erastyle,
Actually the Licensing information for the package is missing hence it is not launching any applications. You need to Reserialize the products using APTEE which you can find it on the Machine where you have created the package. If you dont have the access to that Machine then please download and install Creative Cloud Packager and it will download APTEE in the below mentioned location.
Windows:
C:\Program Files (x86)\Common Files\Adobe\OOBE\PDApp\CCP\utilities
Once downloaded please follow this KB article to use the Tool.

How to delete all objects in a package?

Hello,
I've seen a similar question here. But is there a tool or a smart way to delete all objects in a dev class or a transport request?
Best Regards
Volker

These are really 3 questions??
1. To delete objects in a request there are a number of ways, here is one:
Position cursor on modifiable request.
Double click on request and choose 'Objects' tab
Choose object line you want to delete and click 'Delete'
Save your changes.
2. To delete objects in a Dev Class:
Go to work bench --> edit object, Class and give your class name, you will see delete option at the bottom of the screen.
3. How to delete all objects in a package:
here is a link with the steps you need for this: http://benxbrain.com/en/index.do?onInputProcessing(brai_object_thread)&001_threadid=0000161442&sysid=WP5&pgmid=R3TR&object=DOMA&obj_name=DEVCLASS&child_param=

Find classes in a package

I'm new to java. What's the best way to find all classes in a standard package (e.g. java.awt). I'm trying to create a list for classes in a package in java.
thanks

I guess you're talking about finding them in a running program (like scanning).
Well, I'm searching a solution for a similar problem.
Unfortunately, java classes are loaded on demand. That is, if you're not using kung.foo.MyClass in your code, its not known by the vm, so you can't find it using VM calls.
Since this behavior is the same for packages, you can test this behavior if you're scanning packages using Package.getPackages():
public class PackageTester {
// drops the package info on screen.
public static void listAll (String message , Package [] data) {
    System.out.println ( ) ;
    System.out.println ( message) ;
    System.out.println ( "Amount of passed classes : "+data.length) ;
    for (int i = 0 ; i < data.length; i++)
          System.out.println ( data.toString()) ;
public static void main (Strinbg [] args) {
// get a list of all known packages
Package [] state1 = Package.getPackages() ;
// load a yet unknown class
MyClass kong.foo.myClass = new kong.foo.MyClass () ;
// reload all packages
Package [] state2 = Package.getPackages() ;
// print lists to screen
listAll ("packages before loading MyClass" , state1) ;
listAll ("packages after loading MyClass" , state2) ;
Didnt check, but the code should compile.
This means that, if you want to scan for classes in the vm, you'll have to say the vm which classes you're scanning for. Of course, this is nonsense.
The most complete way is to scan all files starting at the classpath-entries, and looking for .class-files in directories and .jar/.zip-files. This is much work to do, but it seems to be the only useful solution to solve this nasty problem. You could use tools, which surely are available; but its not an elegant solution.
Sorry.

How do I retrieve all data from a table and display it on a text area?

Flex Gumbo - Library Path "Include all classes" includes ActionScript Files

I've added an "Actionscript File", i.e. a File with no package/class that is included in an actionscript class.
In FlexBuilder 3, since there was no option to include all classes, I could optionally choose actionscript files.
So, Make Flashbuilder's "include all classes" option to not include Actionscript Files by default.

How can I retrieve all row information from a database table.

I have a jsp file which calls info from columns in a table. My question, is how can I edit it so that it retrieves all the rows?
I tried using resultset SalesInfo.next() which only retrieves the last row value and resultset SalesInfo.first() which only retrieves the first row value.
Here is my code
public ResultSet SalesInfo;
public void getSalesInfo()
          try
               Statement stmt = db.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);
               SalesInfo = stmt.executeQuery("SELECT sales_id,cust_id,product_id, quantity from sales;");
               SalesInfo.first();
               setCartsales_id (SalesInfo.getString("sales_id"));
               setCartcust_id (SalesInfo.getString("cust_id"));
               setCartProduct_id(SalesInfo.getString("product_id"));
               setCartquantity (SalesInfo.getString("quantity"));
          catch(SQLException e )
               setCartsales_id(e.toString());
               e.printStackTrace();
Also I apologise for not having the proper code format as I had a problem with my keyboard.

     public class SalesDB{
    public static synchronized Vector getSalesDetail(Connection connection) throws SQLException{
        String query = "SELECT * from Sales;"
       Statement statement = connection.createStatement();
        ResultSet results = statement.executeQuery(query);
        Vector sale_details = new Vector();
        while(results.next() == true){
     SaleInfo saleInfo = new    SaleInfo(results.getString("sales_id"),results.getDouble("cust_id"),results.getString("product_id"));
            sale_details.add(saleInfo);
        results.close();
        statement.close();
        return sale_details;
}

Finding all classes in a path

I am writing a utility in which I want to find all classes with a specifed pattern, i.e. "com.ourcompany.ut.*_UT". I know that I could recursively go through the directory com/ourcompany/ut and find files named "*_UT.class", convert the path info to a package name, and use Class.forName to load the class. Is there a cleaner way to do this?

Is there a cleaner way to do this?No. You have to search for the classes in the file system (or JARs or whatever) if the class isn't already loaded.
