  • How to call a stand alone java application from ADF BC JSP, struts or JSF

    My requirement is that there are utilities or stand alone java applications that I want to call from our existing applications.
    We have two seperate applications one ADF BC Struts application we developed using JDeveloper 10.1.2 and another ADF BC JSF application we developed using JDeveloper
    We want to integrate applications like JTwain and others to help us in scanning. The application will be placed on the same server as our application. How can I do this without loosing all the current session information.
    Please help.
    Thanks and regards,

    There are two possible solutions.
    First, if the tool or application you want to integrate, has an Java-API you can use this api and integrate the tool in your application (using one or more jars you add to the classpath).
    Second, if the tool has no java api, you can call the tool via runtime.exec(...) as a shell process. This way you open a command shell in you application and execute the tool like you do on a normal command shell.
    For tide integration and control I recommend the first approach. The second one is only for those tools which don't offer a java api.

  • How to call a WD JAVA application from a WD ABAP application

    Hi experts,
    Here I have two applications with me. One has been created through WebDynpro ABAP while the other one has been created through WebDynpro JAVA. Now i have to call upon the JAVA aplication from my ABAp application. In other words in need to integrate both the applications so as to have an easy navigation in between them.
    In the whole process I need to take care that the data is not lost from both ABAP or JAVA side.
    Please help me someone knows the solution.
    Kaustubh Maithani

    Usally to run WebDynpro for Java Application, we get the Application URL.
    If you want to call this WebDynpro Java Application from Webdynpro Abap, then create UI element like Link to Action or LinktoURL and give the url as WebDynpro for Java URL.

  • Problem while calling a Webservice from a Stand alone java program

    Hello Everyone,
    I am using a java program to call a webservice as follows. For this I have generated the client proxy definition for Stand alone proxy using NWDS.
    Now when I call the method of the webservice I am getting the correct result but along with the result I am getting one error and one warning message in the output.
    The java code to call the webservice is as follows.
    public class ZMATRDESCProxyClient {
         public static void main(String[] args) throws Exception {
              Z_MATRDESC_WSDService ws = new Z_MATRDESC_WSDServiceImpl();
              Z_MATRDESC_WSD port = (Z_MATRDESC_WSD)ws.getLogicalPort("Z_MATRDESC_WSDSoapBinding",Z_MATRDESC_WSD.class);
              String res = port.zXiTestGetMatrDesc("ABCD134");
    The result I am getting is :
    Warning ! Protocol Implementation [] could not be loaded (NoClassDefFoundError) !
    Error Message is :com/sap/guid/GUIDGeneratorFactory
    <b>Material Not Found</b> -
    > This is the output of webservice method and it is right.
    Can any one please let me know why I am getting the warning and error message and how can I fix this.

    Hi Abinash,
    I have the same problem. Have you solve that problem?
    I am using a java program to call a webservice too. And I have generated the client proxy definition for Stand alone proxy using NWDS. When I call the method of the webservice I am getting the correct result but along with the result I am getting one error and one warning message in the output.
    The java code to call the webservice is as follows.
    MIDadosPessoaisSyncService service = new MIDadosPessoaisSyncServiceImpl();
    MIDadosPessoaisSync port = service.getLogicalPort("MIDadosPessoaisSyncPort");
    String out = port.MIDadosPessoaisSync("xpto", "xpto");
    The result I am getting is :
    Warning ! Protocol Implementation [] could not be loaded (NoClassDefFoundError) !
    Error Message is :com/sap/guid/GUIDGeneratorFactory
    <b>The result of the WS is correct!!!</b>
    The Java project does not have any warning. But the stand alone proxy project has following warnings associated with it.
    This method has a constructor name     
    The import javax.xml.rpc.holders is never used     
    The import javax.xml.rpc.encoding is never used     
    The constructor BaseRuntimeException(ResourceAccessor, String, Throwable) is deprecated
    It is very similar with your problem, could you help me?

  • How to call another directory java program?

    Hi All,
    For Example:
    My program is here in two directories.Let Think that directory names like A and B.
    Let Program names like Aprog(A directory) and Bprog(B directory).
    I want to call Aprog to Bprog method.
    How to call?
    Plz., help me ASAP.

    My program is here in two directories.Let
    Think that directory names like A and B.
    It's more complicated than that. A java program consists of multiple .class files. In general you have one or more "trees" of directories of .class files, where the structure of the tree reflects the package structure. So a the class file for "org.dingbat.Thingy" is <basedir>/org/dingbat/Thingy.class where <basedir> is some directory on the class path.
    So referencing one class from another in different directories requires that the source provides the "fully qualified name" of the class (usually on an import) and making sure that, if it's in a different class file tree, both base directories are on the class path.

  • Communication between servlet(client behavior) and stand alone java program

    Hello all:
    I need to send a message (ascii characters sequence) from a servlet to a java program, but I'm not sure what is the best way to get it: socket, JMS or other mechanism that I don't know.
    Is the servlet who is operating how client behavior.
    Please, any comment will be appreciated, regards,

    You can always start a ServerSocket on the client (kinda sounds funny, doesn't it) which will accept connections. You then open a plain old Socket on the server to connect to the client's listener. (Note, this is the reverse of a normal set-up). Once you have the connection established, you will call getOutputStream() to get a stream to write to. Likewise, you will call getInputStream() to read the data sent. You will want to investigate the* and* libraries.

  • How to call  Screen in another program from exsisting program

    Hello Frieds,
    Can any one help me how to call  a screen  in another program (Say "test2") from exsisting program(say "test1')
    If above case is possible then how to access the fields in the target screen?
    Your responce is greatly appreciated.
    Best Regards,

    Hi Rakesh,
    If you wish to use ONLY the screen of another program, call transaction  will not help you, because the called transaction will be fully executed (and not only the screen), and the acess to screen field wil be difficult.
    When you wish to access the same screen from more than one program, you can create this screen in a function module and in this way you can call the function (to display the screen) in many programs.
    Best regards,

  • How can I execute a java program from a Servlet?

    Thank You
    [email protected]

    You could call it via Runtime.exec(), just as you would from any Java program. Or better, you could redesign it as a proper Java class. Then your servlet could create an instance of the class and call its methods as necessary.

  • Calling a external Java method from JSP - using Tomcat server

    Hi all,
    I am trying to call a method in an external Java file from my JSP. I am using Tomcat server.
    I have my class within the package package "mypackage" and it is called myclass.class. It has only one static method mymethod() which reads from a file and writes to a file.
    I compiled the java class and I put the class file under webapps/ROOT/web-inf/classes/mypackage/myclass.class
    I am trying to say something like this from my JSP file(which is under webapps/ROOT) :
    <%@ page import = "mypackage.myclass"%>
    <% myclass.mymethod(); %>
    I am not instatiating the class as its a static method.
    This is what I get while accessing my jsp file :
    javax.servlet.ServletException: try to access class mypackage.myclass from class org.apache.jsp.index_005ftest_jsp
    To put my problem in a nutshell, Can someone guide me how to access a method of an external class from a JSP page? I have a bunch of pages doing the same operation so I thought I would have it in a method and call it from every page. Even though I tried to put the file under web-inf/classes, The JSP is not able to see the class.
    Please help.

    I have a situation that is a bit similar. I have successfully used beans for storing methods used in JSPs and used by other methods in the same class as was suggested above. Now I would like to break some methods into another (utility) class since they are lower level and can be used by lots of things. They are for database operations (given a String query and String dbname, it queries and returns ResultSet for example). I want to have them in a separate class for reusability and OOP.
    I am having problems calling those public static methods in the public class from my bean that communicates with the JSP. I can't compile the class that calls the method in the database ops class. I get an error like : cannot find symbol
    symbol : variable sqlHelper
    location: class dbHelperBean.loginHelper
    and when I include the package name in the call I get cannot find symbol
    symbol : class sqlHelper
    location: package dbHelperBean
    That's strange since the package of both classes is dbHelperBean and the class is indeed called sqlHelper. I tried to compile it in the same directory as sqlHelper as well. What am I doing wrong?
    Thanks for any help.

    What if is on a remote machine i.e. and are on different machines?
    Will I have to use RMI?Well, you'd have to do some kind of remote invocation. Depends on what kinds of apps house the classes. There are all kinds of ways - web services, servlets, RMI, (maybe others...)
    That's a totally different question than what you originally posted, and would have been very relevant to say so in the first place.
