Getting list of classes?

Hello all, I was just wondering if there is any way to get a list of all the known classes in a certain package? I know I can get a list of the packages themselves, but not sure about how to go about getting the actual classes.
Thanks for the help!

If you only want to get a classes list from a jar package,read the api specof java.uitil.jar.
java.uitil.jar privides classes for reading and writing the jar file.
So I think it can satisify your requirement.

How to get list of classes in classpath?

Hi.
I need to get list of classes in CLASSPATH which implements the some interface.
How i can get list of classnames from CLASSPATH ?
TIA

What you want to do is not that trivial.Its not trivial, but its not really all that hard either.
I this thing quite a bit in JUnit tests (e.g, all SomeInterface implementations are expected to be serializable - lets hunt them out and check we can actually serialize them. Turned out to do that I needed a generic yet fairly intellegent object creator / populator: That was significantly less trivial than the other task).

Getting list of classes from a jar

Hi
I want to retrieve list of class names from a jar. i used URLClassLoader and it retrieves pakcage name but i don't know how to retrieve class names

I don't know if this is the best way, but I did this once before like this:import java.util.jar.JarEntry;
import java.util.jar.JarFile;
// then you can do this
String path = "path to some JAR file goes here";
JarFile jar = new JarFile(path);
Enumeration<JarEntry> entries = jar.entries();
while (entries.hasMoreElements())
   JarEntry entry = entries.nextElement();
   String name = entry.getName();
   if (name.endsWith(".class"))
      // this is a class entry
}

Get list of classes present in an applet's Jar file?

I have an applet for drawing diagrams, which is bundled in a jarfile together with classes for each type of element in the drawing (e.g. a class for drawing 2-input NAND gates, a class for J-K flip-flops, and so on). When I add a new type of drawing element I have to modify the applet to add the new class to the applet's "Insert" menu to allow the element to be inserted. What I want to do is to search the jarfile containing the applet for any classes derived from DrawingElement and add them automatically to the Insert menu when the applet is inited. I presume this would require using getClass().getClassLoader() to get the class loader that read the JAR file, but from there it would seem I need to know the name of the resource to load. Is there a way of browsing the list of resources in the JAR file?

AndrewThompson64 wrote:
That 'modify the applet' is not strictly necessary. The list of menu items and classes might be passed to the applet as applet parameters, or as a property file or XML (or whatever) that defines the available elements.I could do this -- I'm just trying to avoid getting the list out of step with the contents (or if you prefer, I'm just being lazy!).
Is there a way of browsing the list of resources in the JAR file?Yes and no. You might try this general strategy (untested).
1) Gain an URL to a resource in the Jar in which the plug-ins exist.
2) Parse that URL for everything before the '!' symbol to get an URL for the Jar itself.
3) Get an InputStream from the Jar via URL.openStream().
4) Get a ZipInputStream by wrapping the InputStream.
5) Iterate the ZipEntry(s) to identify classes in the correct package, and store them in a collection of some type.
6) Iterate the collection and check each one for extending DrawingElement, using reflection.
I am guessing step 6 will require the applet to be trusted.Sounds plausible, and I'll give it a whirl. However, I hadn't thought about the "trusted" bit of this; maybe I can just create new instances and cast to DrawingElement, ignoring any that throw exceptions. I'll have to give it a go and see what happens.
BTW - once you have the right classes, how do you get the screen name of them? Is the name defined in one of the attributes of a DrawingElement? What prevents name clashes?Plan A: I have a getIdentification() method that returns a string identifying the element, but I have to keep this unique the hard way (by hand).
Plan B: use the class name with some prettification (e.g. have a class _2_input_NAND_gate which gets displayed as "2 input NAND gate") so that the compiler does the work of keeping it unique. Not sure I like this, though.
Many thanks for your help.

Func/BAPY to get list of objects from Material class

Hi guys,
I am looking for BAPI/FUNC to get list of material/objects if I know Class and Class type. In MM02 I am doing following: In selection of input I choose Materilas of Class there I write Class and Class type, and then there is icon FIND IN INITIAL CLASS after clicking that icon I get list of materials for entered class.
Can you advise me which BAPI/Func do that or in which tables I can find this DATA.
Thanks very much for any help.
Zbynek

Zbynek,
Try using this BAPI....<b>BAPI_CLASS_SELECT_OBJECTS</b>
Actually you can do this by directly going to tables....
First using the class type and class number, go to KLAH tables... get the Int class no. (KLAH-CLINT). Using this go to KSSK table and use the KLAH-CLINT value in KSSK-CLINT and adda another condition like KSSK-MAFID = 'O'.
Hope this helps...

Why do other browsers ( IE, Chrome, Opera,Safari) list StartCom Class 2 Primary Intermediate Server CA as a Trusted Intermediate Certification Authority but Firefox doesn't?

We are setting up registrations for a paid event and have bought a SSL certificate for our site. Everything works fine when the registration page is accessed through IE, Chrome, Opera or Safari (which list StartCom Class 2 Primary Intermediate Server CA as a Trusted Intermediate Certification Authority), but when I click on that link in Firefix I get the "This Connection is Untrusted" page because only StartCom Class 1 is listed as trusted.
Why is that?

It is always the responsibility of a website to send the complete certificate chain.
You can check the certificate chain of breastfeedingconference.asn.au and see that the server doesn't send the intermediate certificate.

Powershell script to get list of softwares installed as shown in registry on all the remote systems in a txt file

Hi
I need to know the command for getting list of softwares installed on all the remote systems in network which are existing in their respective registry like HKEY_LOCAL_MACHINE\SOFTWARE of all other systems

Hey
Sorry this isn't powershell but it should do the job if you want to use it. The problem with using the Win32_Product WMI Class to enumerate the installed software (especially on Windows 2000 & 2003 Servers) is that the WMI class is NOT installed by default. Here is a VBScript i wrote to read a list of hostnames from a text file named "ComputerNames.txt" from the scripts directory and attempt to remotely enumerate all subkeys within the following registry key
HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall
For each subkey enumerated it will attempt to read the value of the "DisplayName" key and output the results to a csv file.
(the results should be the same as what you would see when you open Add/Remove Programs)
Hope that helps
Cheers
Matt :)

Getting Bad Applet class name exception while opening applet.

Hi,
While opening an applet in my mac os x v10.6.8 machine i am getting "Bad Applet class name exception" which is working fine in mac os x v10.7.5.Java version in my mac is 1.6.0_43.Can anyone please help me to resolve this.

Apple barred Java from running on Macs in order to safeguard users by blocking Java 7 Update 11 and adding it to the banned list in XProtect.
This was the second time in two weeks that Apple had blocked Oracle's code from running on Macs. The threat was so serious that the U.S. Department of Homeland Security had recommended that all Java 7 users disable or uninstall the software until a patch was issued. This time Java is blocked through Apple's XProtect anti-malware feature.
Java has come under fire as the means by which hackers have been able to gain control of computers. In April 2012 more than 600,000 Macs were reported to have been infected with a Flashback Trojan horse that was being installed on people's computers with the help of Java exploits. Then in August Macs were again at risk due to a flaw in Java, this time around, there was good news for Mac users: Thanks to changes Apple has made, most of us were safe from the threat.
Unwilling to leave its customers open to potential threats Apple decided it's safer to block Java entirely.
In order to block older versions of Flash, Apple has updated its "Xprotect.plist" file so that any versions that come before the current one (version 11.6.602.171) cannot be used on a Mac. Users who have older versions of Flash installed will be greeted with an alert that says "Blocked plug-in," and Safari will prompt the user to update to a newer version.
Macs running OS X Snow Leopard and beyond are affected.
UPDATE for those running Lion or Mountain Lion:
Oracle on Friday February 1 released a new version reportedly addressing vulnerabilities seen with the last build.
Apple disabled Java 7 through the OS X XProtect anti-malware system, requiring users to have at least version "1.7.0_10-b19" installed on their Macs. The release dated February 1 carries the designation "1.7.0_13-b20," meeting Apple's requirements.
Oracle "strongly recommends" applying the CPU fixes as soon as possible, saying that the latest Critical Patch Update contains 50 new security fixes across all Jave SE products.
Update for Snow Leopard users:
Apple issued update 12 for Java for OS 10.6:
http://support.apple.com/kb/DL1573
Note: On systems that have not already installed Java for Mac OS X 10.6 update 9 or later, this update will configure web browsers to not automatically run Java applets. Java applets may be re-enabled by clicking the region labeled "Inactive plug-in" on a web page. If no applets have been run for an extended period of time, the Java web plug-in will deactivate.
If, after installing Java for OS X 2013-002 and the latest version of Java 7 from Oracle, you want to disable Java 7 and re-enable the Apple-provided Java SE 6 web plug-in and Web Start functionality, follow these steps:
http://support.apple.com/kb/HT5559?viewlocale=en_US
Further update:
Apple issued this Java related security update No. 13 on February 19:
http://support.apple.com/kb/HT5666
and Update No. 14 on March 4: http://support.apple.com/kb/DL1573
http://support.apple.com/kb/HT5677
You should also read this:
https://support.apple.com/kb/HT5672
The standard recommendation is for users to turn off Java except when they have to use it on known and trusted websites (like their bank). Javascript, which is unrelated despite the name, can be left on.

Better way how to get list of all classpath URLs in runtime

Hello everyone,
How to get list of all classpath items (URLs) in runtime from Java code?
I am aware of solution based on System.getProperty("java.class.path"). Is there any alternative?
This solution has several drawbacks. You have to parse String output. And I not sure if it contains ALL resources (JARs, class directories) loaded by ClassLoader or just reflects -cp arguments.
Does system property "java.class.path" contain ALL loaded JARs?
Does it contain items (JARs, class directories) loaded by bootstrap classpath?
What about JARs loaded in runtime?
Is the separator ":" always same on all operation systems?
I was looking for some Java API based solution, method like List<URL> getAllClasspathItems()
But there is nothing like this in ClassLoader, Class, Runtime or System classes.
For curious, here is code I use.
String classpath = System.getProperty("java.class.path");
StringTokenizer st = new StringTokenizer(classpath, ":");
while (st.hasMoreElements()) {
System.out.println(st.nextElement());
}

For curious, here are output prints for all 3 methods:
1) parsing system property
2) tschodt
3) overcast SystemClassLoader to URLClassLoader

...Interestingly, method 1 and 3 gives the same list, same order, same count, just format of item is a little bit different. The order is same as in Eclipse .classpath file.
Method 2 (tschodt) give significantly more items! rougly 3x! Different order (somewhat random it seems to me). Some items contain extra information, like version and string "Java Platform API Specification".
It prints not absolute paths but logical Java names.

Need to get list of all portlet instances in system

Hi guys
Probably such question already was here, but I cant find any solution.
I need to get list of instance labels of all portlets used on all desktops in current domain.
Thanks for help.
Edited by AndreW at 04/08/2008 8:23 AM

Hi
you havent told me the version you are using.
For 8.1 (and i suppose you should have similar classes in 10)
get a IDesktopDefinitionManager from the DesktopDefinitionManagerHome
IDesktopDefinitionManager.getDesktopDefinitions --> gets all the definition
for each definition IDesktopDefinitionManager.getDesktopView
from the desktopView get the Primary BookView.
recursively go through the book view to get getNavigableView . if the navigable is itself a BookView , recurse. if it is a pageView then get the PlaceableView. If the placeable view is of type BookView then do the recursive stuff, else if it is a PortletView you have what you want.

Obtaining list of classes used in an application

I want to be able to obtain a list of all the classes and interfaces that an application uses
I have been looking at the Class Object but with limited success
I can get only limited things from the class
eg the superclasses, interfaces, innerclasses, and public variables
but I want to be able to get which private classes are used also
the code below shows my test code to get info about a class
Class testClass = (new java.awt.Panel()).getClass();
Class classList[] = testClass.getClasses();
for(int i = 0; i < classList.length; i++)
     System.out.println("class "+i+" = "+classList);
Class innerClassList[] = testClass.getDeclaredClasses();
for(int i = 0; i < innerClassList.length; i++)
     System.out.println("innerClass "+i+" = "+innerClassList[i]);
java.lang.reflect.Field fieldList[] = testClass.getFields();
for(int i = 0; i < fieldList.length; i++)
     System.out.println("field "+i+" = "+fieldList[i]);
java.lang.reflect.Field innerFieldList[] = testClass.getDeclaredFields();
for(int i = 0; i < innerFieldList.length; i++)
     System.out.println("innerField "+i+" = "+innerFieldList[i]);
Object interfaceList[] = testClass.getInterfaces();
for(int i = 0; i < interfaceList.length; i++)
     System.out.println("interface "+i+" = "+interfaceList[i]);
Class nextSuper = testClass;
while(nextSuper != null){
     System.out.println("Class "+nextSuper);
     nextSuper = nextSuper.getSuperclass();
The reason that I want to do this is:
When I use an application I want to be able to get the version of each of the classes I use.
Ideally I would build up a set of classes used in the application (and the classes that those classes use, etc, etc)
as I did this I would filter for things that start with my class hierarchy.
and I would save the public String of each class that stores the version.
Then heypresto I would have a list of all the classes of mine that are used and their version numbers.

The idea is to write your own class which extends classloader, then use an instance of that to load the program you're trying to examine. When java wants to use a class it calls a classloader giving it the class name and package e.g. "java.lang.String". The classloader then checks to see if the class is already there, and if not attempts to load it, usually from a .class or .jar file.
When classes loaded with a particular class loader go looking for other classes they call the classloader than loaded them.
So if you load your main program class through your own classloader then any classes it demands (and those they demand), will also be looked for through your classloader. Since class loading is a dynamic process you actually need to run the application (having loaded your main class use getMethod to get the main method then Method.invoke(..).
Mind you if java -verbose:class does the job (and it looks to me like it does) that's a lot simpler.
Just run your program with that and analyse the resulting list of load events.

How do I list all classes in a Jar file?

How do I list all classes in a Jar file?

Its no problem if the jar file contains classes, but I have an EAR file, which contains a jar-file, and I want to list all classes in that jar-file.
I would like to do something like this:
java.util.jar.JarFile jarfile = new java.util.jar.JarFile( new File("/meYear.ear"), true );
java.util.jar.JarEntry jar = jarfile.getJarEntry( "myJar.jar" );
// Cast it to a new JarFile:
java.util.jar.JarFile newJar = (java.util.jar.JarFile)jar;
But the method getEntry returns something like jarFile$JarEntry, if I try to class cast it I get an classCastException.

Complete list of class IDs and names

Is there a complete list of all the built-in class IDs with their corresponing names?
I have looked at the LV2012 Class ID Property help page located here: http://zone.ni.com/reference/en-XX/help/371361J-01/lvprop/gen_class_id/, but this is incomplete. For example, the RadioButtonsControl has an ID of 72 and is not listed.
Or better yet, are there any VIs out there that can convert a U32 ID value into the corresponding class name?
Solved!

I've taken Paul's VI and expanded it to loop through a few hundred numbers and ignore any errors. I've also downcasted it to 2009 for you. Hopefully this is the complete list you're looking for.

How get list AttrNames

Hi,
I created with JDeveloper (version 10.1.3.2) a simple ADF Swing application. I used class JTable and data bindings. But could not get some informations from page definition in my java code. Yes, I had a file "*PageDef.xml", where I saw values^
<pageDefinition>
<bindings>
<table>
<AttrNames>
<Item Value="Name"/>
I need to get list "AttrNames", but I did know how!
Please, help me!
Thank.

Did you not see the properties associated with findGlyphPreferences? Your query isn't entirely clear, but I'm guessing you're after something like this:
app.findGlyphPreferences = null;
app.findGlyphPreferences.glyphID = myId;
myDoc.findGlyph();
Though if you want to find all the glyphs in a document you wouldn't need findGlyph, would you?
