Invoking remote java classes/methods

Hi,
I just wanted to ask for opinions and suggestions regarding my attempt to call a remote java class method using PL/SQL. I didn't want to load it in the database since the configurations for the java class were already set using Spring Integration. I just wanted to supply constructor arguments and run the method and then retrieve the result. Are there any good or easier ways on doing this?
Thanks in advance

Very curious Susan,
A server JVM might not want to host mobile code from other clients, not that it's unsafe, it's just that it allows clients to crash the server JVM at will. They should have it configured to automatically restart though.
Did they delete the java.rmi.* packages from the server JVM runtime? I don't understand why they'd do that.
If you can pry some reasons from them, I'd be very interested to hear them. Perhaps they just want more money, in order to allow you this privilige.

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,
Balu

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

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,

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

Hi All,
I have a requirement to invoke a Java class from the BPEL process;

How to write javascript in java class method

Hi,
any one please resolved this,
i want to write javascript window closing code into java class method, in that method i want to write javascript code & wanted to call in jsf page on commandButton action event,
my code is below but it is not working properly
public void closeWindowClicked(ActionEvent event) {
          try
     FacesContext facesContext = FacesContext.getCurrentInstance();
     String javaScriptText = "window.close();";
     // Add the Javascript to the rendered page's header for immediate execution
     AddResource addResource = AddResourceFactory.getInstance(facesContext);
     addResource.addInlineScriptAtPosition(facesContext, AddResource.HEADER_BEGIN, javaScriptText);

/*Note- i want to closed the window by caling method contain javascript only, i don't want any ajax code in method */
please any one can resolved this.
Thanks

/*Note- i want to closed the window by caling method contain javascript only, i
don't want any ajax code in method */ When the user presses your button, do your business logic and then send them to a page containing the following (note: untested code ahead):
<html>
<head>
    function onLoadHandler()
        window.close();
</head>
<body onload="onLoadHandler();">
    <p>Window closing....</p>
</body>
</html>

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

How to pass value from Javascript function to a Java class method

Hi All,
I want to pass a value, which I catch in a Javascript function to a method in a Java class. I have tried many combinations but it gives me error.
This is the way I am doing
function assignBill() {
proj = projPh.substring(0,indSlash);
<% myproject.getProj(" project_cd = '" + proj + "'");%>
proj is the variable which I want to pass to getProj methods.
If any one has done this, please let me know. Thanks for your help.

The only way to receive something from clients page is to submit it somehow: through a form or link, but the info has to make it back to the server obviously. I dont know how your app works, but you can use the the javascript -location.href- function(i think) to submit the var to the server and process it there.

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

Hi ,
In your java project frm jdev..right click and choose general and then choose deployment profiles and then choose Jar ..and then give some appropriate name(abc) and then click ok.
Then under resources file u get a abc.deploy file right click and say deploy to jar ..u will find the jar in that director.Now include this jar in your prjct libraries.
have a look at the link http://niallcblogs.blogspot.com/search/label/embedded%20Java

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.
cheers
