Execution of a Java Class on a remote machine (RMI ??)

Hi guys,
I have an application in Java which, processes a local file and return some results. The local file is so huge (> 2Gb).
I need to process some distant (remote) files with this application. Firstly, I thought to make a FTP or HTTP connection to remote file and get an InputStream of that and give this InputStream as input to my application. But according to the size of file and transfer rate it's not a good solution may be a bad one.
So, I try to find a solution to send my application (Java Class) to remote machine and request its execution there. Like this, the application will execute locally on remote machine and then I just take the results via network.
I dont know exactly if it's possible or not. I think to RMI or COBRA techniques. But I dont know these methods at all. Does RMI let to send a java class (in fact some class which are dependent) to a remote machine and execute it there and take the results? If yes, I wonder what are the constraints and needs? specially in machine characteristics level?
Or any other solution to execute an Java code locally on a remote machine?
many thanks guys
Hassan

Thanks Pantony,
It's what I want to do. But as I saw to use RMI, wa have to have the remote objects (methods) on host. Then we can call them remotely.
It's nice solution.
BUT, I wonder if there is not possibility to have the remotes method on host side, can we, for example, copy automatically an executable version of application to host and then call it remotely? then take the results saved in a file on host.
If yes, so why RMI? why the remote objects?
And how we can execute a *.JAR (java executable) on a remote machine?
Many thanks
Hassan

How to start/stop/restart a java desktop application from remote machine

Hi,
I want to know is there a way in java where i can start/stop/restart a java desktop application running on a remote machine through another java desktop application?
For e.g i have an Admin console which monitors its clients based on socket communication, all of them are java desktop applications. I want to also give start/stop remote clients through my Admin console.
I am thinking in terms of windows system service which can start/restart/stop my clients on request of Admin console, but how can i call this system service remotely?
How can i do it?

I got it. its about connection...

Execution problem a stored java class

Hi,
I loaded a java class ("ConvertisseurXMLPDF") in an oracle 8.1.7 database and in a specific schema "SCHEMA1".
I loaded it with the loadjava command included the -synonym and the -grant attributes to create the public synonym on this class and the grant execute to a role "ROLE1".
Problem :
I connect with a user "USER1" which is associated to the role "ROLE1" (so, he should have the execution privilege on the class) and
When I execute the procedure which launches the execution of the java class, I have the following error message :
java.lang.illegalAccessException
at java.lang.Class.newInstance0(Class.java)
at java.lang.Class.newInstance(Class.java)
at ConvertisseurXMLPDF.createParser(ConvertisseurXMLPDF.java:162)
at ConvertisseurXMLPDF.converssion(ConvertisseurXMLPDF.java:162)
It seems, it does not even achieve to instantiate the class!
What could be the reason of this problem?
Thanks in advance

Make sure you have the following privileges:
grant javasyspriv to schema1;
grant javauserpriv to role1;

How do I call a simple java class from a bpel process?

Hi.
In JDeveloper 10.1.4.3.0 I've created a simple java class that does an ftp get operation followed by an unzip. The class uses some 3rd part libraries (jars).
I want to use a simple bpel process to schedule a daily execution of this java class, and deploy it all to our SOA-server, - and was looking into using the <bpelx:exec> function.
The java class and the bpel process is all stored in the same JDeveloper project.
How do I put this together so that both my java class and the necessary jars are available to the bpel process?
I've looked into the JavaExecSample.bpel, and it's says something about "...the class com.otn.samples.javaexec.CreditCalculator is locally packaged with this BPEL process".
How do I do that?
Can I make it and test it all locally from my workstation (only JDeveloper installed, I guess there's nothing that can execute the bpel code?), or do I have to compile class etc (make war-file?) and deploy to SOA server (BPEL-INF/lib or classes?) before anything can be tested?
(I guess all this is simple, once you know how, but being a newbie to this I need a shove in the right direction :-)
Regards,
-Haakon-

To create a java class and dependent jars inside the BPEL process project you need to do the following:
1. Right click on your BPEL process project and select New and then Java Class from the Items.
2. Make the BPEL process project, JDeveloper would compile the java classes and add them into the BPEL suite case jar, see the output folder and check the BPEL suite case jar file for java classes and dependent jars.
You can test your Java classes from JDeveloper IDE, no need to deploy the classes on SOA server. When you make the BPEL project it compiles .bpel files and Java classes. You can test your classes once .bpel file and java classes compiled successfully.

Starting a JVM on remote machine

Hi all,
I would like to be able to start a JVM from machine A on machine B. Machine B could be running at another location so I'm not able to start the VM using the command line.
I know you could start a telnet session from A to B and start the process manually but I would like to be able to start the process on machine B using code running on machine A.
Has anybody ever done somthing like this? Any help will be greatly appreciated.
Kind regards,

Hi,
Thanks for reading my post.
Somebody pointed me to RMI and rmid to fix my problem and indeed I think I could use this to initiate a java process on a remote machine without the need to actually sit at that machine.
I'm following the tutorial at http://www.doc.ic.ac.uk/csg/java/1.3docs/guide/rmi/activation/activation.1.html but I keep getting the same error :
Exception in thread "main" java.lang.NoClassDefFoundError: examples/activation/Setup
All classes including stub and skeleton are located at : j:/app/prj/activation/classes
This is how I start the Setup :
C:\>J:\app\lib\j2sdk-1.3.1_06\bin\java -Djava.security.policy=j:/app/prj/activation/policy -Djava.rmi.server.codebase=file:///j:/app/prj/activation/classes/ examples.activation.Setup
Is there anyone who can help me with this?
Kind regards,

How to use URL class to execute a java class/app on a remote machine?

I am a beginner in Java networking and have a question about URL programming.
How do I pass parameters to a java class/application over the web and then cause it to execute ? I then want to get the result back from the clas/app. The class/app resides on a remote machine and the protocol used is "http" protocol. OR all this is not possible through the URL and related classes ?

How do I pass parameters to a java class/application over the web and then cause it to execute ? Using the HTTP protocl you can either perform a GET where the parameters are in the URL or a POST where the data is sent to the server with the request.
The server must be setup as a web server to execute code based ojn a HTTP request. Using a web server with a JSP which contains the code to execute is the simplest way to do this.
I then want to get the result back from the clas/app. The output of the JSP becomes in the data returned by the HTTP request.
I would suggest looking for example on google.
http://www.google.co.uk/search?q=java+http+request+tutorial
Another option is to use RMI. The integration is tighter but it does not use the HTTP protocol.

Trace java class execution

hi all,
I had a terrible experience recently. There was a Java class which creates some reports and uses some libraries also. This program was developed very primitively and exceptions not handled properly. Last time I observed that program is running and but no output and but no error prompted. (because exception was catched but not handled no even a system out).
So I would like to know any method or technique to trace the situation of class execution and find what operations are blocked

IndiikaYou could use AspectJ to add logging, but a simple thread dump can give you information on blocked threads.

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.

XSLT Mapping with Java class not working in Integration Repository

Hi,
I have an XSLT mapping program with Java enhancement and I was able to successfully tested it in Stylus Studio. However, when I imported the Java class and the xslt program in Enterprise Service Builder and tested it, my program does not compile.
Here is the error message: "Transformer Configuration Exception occurred when loading XSLT mapping_temp.xsl; details: Could not compile stylesheet".
My java program is in a zip file containing SOAPHeaderHandler.java and SOAPHeaderhandler.class. My Java has a package com.nga.xslt.
Here is the declaration of my Java class in the XSLT: xmlns:javamap="java:com.nga.xslt.SOAPHeaderHandler"
It seems that it could not read the java class. Can you please advice what is wrong?

Hi ,
select XMLTOOLKIT option in Operation mapping and execute it.
I am not sure we can call java program in XSLT Program,but alternative is copy the code and use it in XSLT mapping it self,that means your XSLT program will become with JAVA extensions.
then in Operation mapping level select SAPXMLTOOL kit option and execute it. i hope it will work. if it is not working then you have deploy some JAXP files on server,because the way execution of XSLT Mpaping program got changed,like when eve you executing XSLT with extnasions( if you are not using XMLTOOL kit option) then you have to use latest version of JAXP.JDK files.

How to create java classes when multiple xsd files with same root element

Hi,
I got below error
12/08/09 16:26:38 BST: [ERROR] Error while parsing schema(s).Location []. 'resultClass' is already defined
12/08/09 16:26:38 BST: [ERROR] Error while parsing schema(s).Location []. (related to above error) the first definition appears here

I tried genarate java classes from multiple xsd files, but getting above error, here in .xsd file i have the <xe: element="resultClass"> in all .xsd files.
So I removed all .xsd files accept one, now genarated java classes correctly. but i want to genarte the java classes with diffrent names with out changing .xsd
Can you please tell me any one how to resolve this one......
regards

Gregory:
If you want to upload several Java classes in one script the solution is .sql file, for example:
set define ?
create or replace and compile java source named "my.Sleep" as
package my;
import java.lang.Thread;
public class Sleep {
public static void main(String []args) throws java.lang.InterruptedException {
if (args != null && args.length>0) {
int s = Integer.parseInt(args[0]);
Thread.sleep(s*1000);
} else
Thread.sleep(1000);
create or replace and compile java source named "my.App" as
package my;
public class App {
public static void main(String []args) throws java.lang.InterruptedException {
System.out.println(args[0]);
exit
Then the .sql file can be parsed using the SQLPlus, JDeveloper or SQLDeveloper tools.

Any difference in creating a web service from a java class or session bean?

Hi,
The JDeveloper tutorial at http://www.oracle.com/technology/obe/obe1013jdev/10131/devdepandmanagingws/devdepandmanagingws.htm demonstrates creating a web service from a plain java class. I'm wondering:
- Is it possible to create a web service from a stateless session bean instead of a java class? If so, what's the proper way to do this in JDeveloper? When I tried doing so in JDeveloper 10.1.3.0.4 (SU5) using the J2EE Web Service wizard, the wizard did not list the session bean in the Component To Publish dropdown (it does list any java classes available in the project). I can proceed by manually typing in the name of the session bean. After the wizard completes though, the @Stateless annotation that had been in my session bean class code is removed and replaced by a @WebService annotation. The end result is that it looks like it made no difference whether I had tried to create the web service from a session bean or plain java class as the annotations in the resulting web service code are the same (although if I had started from a session bean, the class for the web service still implements the Local/Remote EJB interface that the session bean originally implemented).
- Assuming it's possible to create a web service from a stateless session bean, is there any advantage/disadvantage creating a web service from a java class vs a stateless session bean? I'm creating the web service from scratch so I also need to either build the java class or stateless session bean the web service would be based on from scratch too.
Thanks for any ideas about this.

Hi,
EJB Session beans (EJB 3.0) are deployed as WebServices by annotating the class with @WebService and the methds with @WebMethod (both tags require you to add the JSR-181 library to your project (available in the JDeveloper list of libraries)). Unlike the J2E WebService, the EJB session bean service is turned into a WebService upon deployment. This means you obtain teh WSDL file after deployment
- Assuming it's possible to create a web service from a stateless session bean, is there any advantage/disadvantage creating a web service from a java class vs a stateless session bean?
The difference is that EJB Session bean based web services are integrated with the J2EE container, which means that they can leverage container services like transaction handling, data sources, security, JMS etc.

Running a "heavy" program from within a java class

Dear Java programmers,
I 'm trying to run a software called surflex from within a java class, using the following java command:
Runtime.getRuntime().exec( new String[ { "/bin/bash", "docking_script_2.bash"} );
For convenience I've created the following simple bash script but for some strange reason surflex is not executed:
#!/bin/bash
surflex-dock-v211-linux.exe proto drug.mol2 receptor_hydro.mol2 p1;
surflex-dock-v211-linux.exe dock drug.mol2 p1-protomol.mol2 receptor_hydro.mol2 >& 1OHR_A_output.txt;
Can anybody help me on that (ignore the arguments, they are correctly set)? I'll try to find another, more generic example, but so far I've noticed that the same thing happens with unix grep command.
thanks,
Tom

I think if you want to invoke a bash shell and give it a command to execute, you need to do
/bin/bash -c commandrather than
/bin/bash commandAccordingly, your call to exec should look like
exec( new String[ { "/bin/bash", "-c" "docking_script_2.bash"} );Beyond, that, I'd suggest the following as general debugging tips and best practices:
* As the first line of the bash script, include a line that does something simple, like touch a file, so you can see if the script is executing at all.
* In Java, call Process.waitFor(). Its return value is the process' exit value.
* Make sure you're gobbling stdout and stderr from the process, and giving stdin any input it needs. You'll have to do this for the process to run correctly, and you can also use what you read from stdout and stderr to debug the execution of the process. [http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html]
* You may wan to look into ProcessBuilder, rather than Runtime.exec. I haven't used it myself yet, but apparently it's supposed to be the preferred way to execute external processes.
