How to invoke a java class dynamically?

Hi all,
In my usecase I need to invoke a java class dynamically using any of the components like Button or link in jdeveloper.
How could we invoke a java class which has a main method in it dynamically.
Kindly come up with your help.
Thanks,
Phani.

public class BackingBean {
public BackingBean() {
super();
public void cb3_action() {
File fileObj = new File("C:\\Jdeveloper software\\new.doc");
IDocument myDoc = new Document2004();
myDoc.addEle(Heading2.with("===== Headings ======").create());
myDoc.addEle(Paragraph.with("This doc has been generated by the unit test testJava2wordAllInOne() in the class DocumentTest2004Test.java.").create());
Table tbl = new Table();
tbl.addTableEle(TableEle.TH, "Name", "Number of gols", "Country");
tbl.setRepeatTableHeaderOnEveryPage();

Hi john,
these are my Backing bean and action now at the run time when I am pressing a button which has to invoke cb3_action() method.
When I am clicking the button at the runtime I am getting the below error
Error 500--Internal Server Error

In the above code if you observe I have used "IDocument myDoc = new Document2004();" line. Here this Document2004 is a class which is in one of the external
jar files. xstream-1.3.1.jar , java2word-3.0_2011Aug02.jar , log4j-1.2.15.jar .
these are the jar files I found in net using which I can create a word file and add all the components like table and format the txt etc..
These jar files works in Tomcat, Jboss ,Struts
I can even run this class and got the file created.
But when I try to bind the method in ADF i am getting the error mentioned above.
Kindly help me on this. Sorry for posting similar question two times on the blog.
Sorry again if this question is wierd.
Thanks,

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

How to invoke a Java class constructor in Forms

I want to Run this ( http://persiancalendar.sourceforge.net/) Persian calendar in forms. I am using Forms 10g Rel 2 (Forms [32 Bit] Version 10.1.2.0.2 (Production))
I did this:
(1.) Downloaded the 2 Jar files persiancalendar.jar and icu4j_3_2_calendar.jar
(2.) Deployed jar files in forms\java
(3.) Added entries in FORMS_BUILDER_CLASSPATH and formsweb.cfg
(4.) The 2 jar files get loaded to the JAR cache when form runs.
Now, in order to invoke the Persian calendar according the documentation you have to invoke the constructor in class PersianCalendar.
PersianCalendar() Constructs a Persian calendar with the default time zone and locale.
In Forms the FBean package can invoke only methods. I tried combinations of inputs but without any success.
According to the documentation this is the only class to create a calendar. All other classes are either utilities or get/set methods.
How can I do this?

PersianCalendar() is the constructor of the class; it will be invoked when you instantiate the class. This happens when you register your bean at runtime (assuming you are talking about the FBean Package):
http://www.oracle.com/webapps/online-help/forms/10g/state?navSetId=_&navId=3&vtTopicFile=enhancedjavabean/enjbs_registerjavabean.html&vtTopicId=
But I'd opt for a wrapper; you might even want your own class extending PersianCalendar to make some customizing of the calendar.

Invoking a java class while server start up

Hi,
I want to invoke a java class/method immediately after a web server is started. Can any body tell me how to do this.
Regards,
Prakash

It is easy.
Write a serlvet, lets call it ConfigServlet that handles the configuration parameters of a web-application.
My GenericConfigServlet looks like this:
import java.io.IOException;
import java.io.PrintWriter;
import java.util.Enumeration;
import java.util.Map;
import javax.servlet.ServletConfig;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.log4j.Logger;
public class GenericConfigServlet extends HttpServlet
     private static final long serialVersionUID = 1L;
     public void init(ServletConfig config) throws ServletException
          super.init(config);
          ServletContext sCtx = getServletContext();
          ServletConfig sCfg = getServletConfig();
            String prefix = sCtx.getRealPath("/");
            synchronized (this)
               Enumeration initParams = sCfg.getInitParameterNames();
               String key, value;
               GenericConfigProperties.setApplicationBasePath(prefix);
               while (initParams.hasMoreElements()) {
                    key = (String) initParams.nextElement();
                    value = sCfg.getInitParameter(key);
                    GenericConfigProperties.setProperty(key,value);
}Then in your web.xml, you write like this:
<servlet-name>ConfigServlet</servlet-name>
          <servlet-class>GenericConfigServlet</servlet-class>
          <init-param>
               <param-name>LICENSES</param-name>
               <param-value>1</param-value>
          </init-param>
          <init-param>
               <param-name>TMP_DIRECTORY</param-name>
               <param-value>C:\\temp\\</param-value>
          </init-param>
          <init-param>
               <param-name>INPUTFILE</param-name>
               <param-value>C:\\temp\\_input.txt</param-value>
          </init-param>
          <load-on-startup>0</load-on-startup>
     </servlet>You can add any number of init-param-tags.
The important thing is the element <load-on-startup>0</load-on-startup>. This tells the webserver to load this servlet first. A lower number is loades before a higher so if you have a servlet that you want to load but you need the configuration to be done first, that servlet definition should read <load-on-startup>1</load-on-startup>.
Of course, you can do anything you want in the init-method. This is just one way of doing it.

How do you invoke custom java classes???

Could someone post a detailed method of invoking custom java classes that works including what files go where, settings and the way it is invoked etc.
I have tried various ways from this forum and in the documentation without success. I am using IDM 8. I found these instructions regarding how you would do it if you were writing custom resource adaptors in the deployment tools guide:
To install a resource adapter youve customized:
1. Load the NewResourceAdapter.class file in the Identity Manager installation
directory under
idm/WEB-INF/classes/com/waveset/adapter/sample
(You might have to create this directory.)
2. Copy the .gif file to idm/applet/images.
This .gif file is the image that displays next to the resource name on the List
Resources page, and it should contain an image for your resource that is
18x18 pixels and 72 DPI in size.
3. Add the class to the resource.adapter property in
config/waveset.properties.
4. Stop and restart the application server. (For information about working with
application servers, see Identity Manager Installation.)
I tried the instructions here but placed my custom class in a folder entitled custom instead of /adapter/sample. Not sure about instruction 3 or whether it is relevent. Anyway nothings working.

Hi,
The way to add custom class is the same as you followed , put them in the WEB-INF/classes.
To use the custom adapter ,
Go To Resources - > Configure Types -> Add Custom Resource .
Type in the fully qualified class name of the custom adapter you added.and Save.
Now the new adapter you added should showup in the list of available adapters when you try to
configure a new adapter.
(Make sure that the prototype XML of your custom adapter is correct so that it displays the correct name / type for the adapter in the adapter list.
Thanks,

How to invoke another Java file in Java program?

Hello all,
Now I am building a commnity of agents that can talk in Java, I have another Java-Based dialogue system to handle the dialogue between the agents. But I don'y know how to invoke the Java dialogue system file in the agent class.
Is there any methods can call another .java file in a Java program?
Help!!!!!please

Yep, vaguest of the vaguey vague vague.
Anyhoo,
I'm guessing you want to call a method from a different class?
Assuming you have the "Runner" class and then "Agent1", "Agent2", etc.
Agent1 whatever = new Agent1();

Is it possible to invoke a Java class from Data Services 4.0?

Is it possible to invoke a Java class from Data Services? I have a query transform with a varchar column which I want to run an external java class against to encrypt the string value. In the Management Console, I created an adapter of type TestAdapter and referenced my jar file in the Classpath section, but when I create a Datastore of type Adapter I can't import any functions related to my java class? It seems like I need to create a new Adapter type similar to the TestAdapter with the 'Adapter Class' set to my java class? I can't figure out how to do this - which is the correct approach and is there some documentation available? thanks!

First u nees to imoprt the class which u are doing right
then u need to call the function of the class , and then you can put the value in a string .
DbCon.function()
String data = DbCon.db;
where db is a string in DbCon
Cheers

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()

Trying to invoke a Java class from BPEL Proces using Java Embedding

1) Firing a Trigge
2)Storing the most latest data and pass it to the Parser PROGRAM
Can someone tell me how to do this? How to invoke a Java Program from within the database? Please if anyone has examples provide me. Its very urgent and tell me what is the basic mechanism.

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.
