Than how can i get java class by using it's class file?

Hi
After compilation of a java program, it creates a class file.
After getting class file suppose class file has been deleted.
Than how can i get java class by using it's class file?
Thanks in advance.

get a decompiler and run your class file through it--I'll assume you want the source code back and that you are not trying to recover a missing class file by attempting to use the class file that is missing--if it's missing, then I've not a clue on how to get it back by using what is already missing.
BTW: many of your compilers have source control--if it does, just restore your missing file.

How to call a Java class from another java class ??

Hi ..... can somebody plz tell me
How to call a Java Class from another Java Class assuming both in the same Package??
I want to call the entire Java Class (not any specific method only........I want all the functionalities of that class)
Please provide me some slotuions!!
Waiting for some fast replies!!
Regards
Smita Mohanty

Hi Smita,
you just need to create an object of that class,thats it. Then you will be able to execute each and every method.
e.g.
you have developed A.java and B.java, both are in same package.
in implementaion of B.java
class B
            A obj = new A();
             //to access A's methods
             A.method();
            // to access A's variable
            //either
           A.variable= value.
           //or
           A.setvariable() or A.getvariable()

Thanx a lot for your cooperation .

<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by [email protected]:
Henrik, the Java importer lets you call Java classes on the app server side - I think what Ali is trying to do is integrate on the client side.
If you want to add your own button then if you extend the standard Forms button in Java and then use this class name in the implementation class property then the Java for your button will be used instead of the standard Forms button. And since it has extended the basic Forms button it has all the standard button functionality.
There is a white paper on OTN about this and we have created a new white paper which will be out in a couple of months (I think).

How to load a java class at server start-up

Hi,
I have one custome java class that is being referenced by all the applications deployed in OC4J container. How can I load that class automatically and be evailable in the path at server start-up time. Is there an option available to give the class name that also gets loaded automatically.
Thanks

To me, you have two mixed issues.
1. OC4J supports a startup/shutdown model where a named class will be invoked when the container is started (or stopped).
This is described in the doc here:
http://download-west.oracle.com/docs/cd/B32110_01/web.1013/b28952/startclas.htm#CIHECEIB
Note that this specifically calls the methods that are implemented from the respective OC4JShutdown and OC4JStartup interfaces -- the class that is instantiated and called here is not available to all other applications by default. This is more to suit the need where something needs to be done when the container is started/stopped.
2 The next option is where you just want to make a class available to all applications deployed to the container. For this we provide the shared-library mechanism. Using this you can either make use of the implicit global.libraries shared-lib in which you simply drop JAR files into the j2ee/home/applib directory whereupon the classes will become available by default to all applications. Or you can choose to install a shared-library that contains your specific classes (in a JAR file) and then import that into the default application whereupon the configuration will be inherited by all deployed applications.

How to call a java class in a bat file

Thanks lot

assuming lanch.bat, Test.class and DOM.jar are in c:\url
assuming %JAVA_HOME% is defined (else substitue it with your java installation directory)

cd C:/url (or cd c:\url ) (or cd c: followed by cd url)

How to make a java class act as an cache

Imagine
i have a simple java class which establishes a connection to a DB and has a getter method which returns this DBConnection
Now i want this class to be loaded forever in jvm, i mean, once it starts and establishes connection it remains loaded , and then returns the dbconnection who ever calls its geter method.
So i am wondering what kind of java class do i write that behaves like an cache.
and how would the other classes call this getter method of my class, i mean they cant instantiate it i guess , coz then it creates a new object , i mean i m confused , hope someone provides a soultion
tahnks

1) A class should do relatively litte. It's object-oriented programming. If you feel the urge like making it all static, maybe you can use a singleton, which is accessible using a static method.
2) Nothing what you described matches the term "cache"
3) And what you actually want it a connection pool. There should be several examples on the web.

How to invoke a java class during UCM 10gR3 startup ?

I am integrating AD4J (Application Diagnostic for Java) with UCM (Universal Content Management , earlier stellent) to monitor my UCM's JVM.
This is very simple configuration where I have to add java class (jamagent.jamrun) in my UCM's startup program. This class (jamagent.jamrun) is in zip file ad4jagent.zip which I have added in classpath via intradoc.cfg
JAVA_CLASSPATH_ad4j=$SHAREDDIR/classes/jamagent.zip
Issue now is that I am unable to find java [content_server_startup_class] so can't add class jamagent.jamrun .
As per my understanding : idcserver_start -> idcserver_ctr -> Launcher.sh -> Launcher (This launcher is executable)
I am unable to understand where or how can I invoke jamagent.jamrun class with my UCM startup ?

Java-code in a custom component could be triggering on a filter event that occurs during the startup of UCM, like extraAfterConfigInit. Would that be sufficient for loading yourAD4J?
Other than that, it is my understanding that every jar that you put in the classes folder of UCM is loaded on startup.
I hope this helps.

Wim
