Java foundation classes

I have a project to look at the java foundation classes and try to show where a design pattern has been used in its development.
Firstly I dont know where to find the Java Foundation Classes on my pc.... I am presuming there are source code files for them?
Can anyone point me in the right direction?

You should have a src.zip in the dir that you installed the sdk in.

  • Foundation classes is there a download pool somewhere?

    Hello all,
    i am new to Java ....
    I am just trying to comile some code from my book with the following import lines
    import java.applet.*;
    import java.awt.*;
    import com.ms.ui.*;
    import com.ms.fx.*;
    I get the error that javac can't find the "com.ms.ui.*" package.
    I know "com.ms.ui."classes are from Microsoft. But where can i get them. I searched in the internet and didn't find a download place. The follwing adress don't works "http://air.knu.ac.kr/reference/COM/afc.htm"
    My question now. Is there a place in the internet where all (foundation) classes are for download, or does somebody know where i can download the AFC from microsoft? Because i am new, is there a place where somebody should start for searching when he is locking for some classes or packages.
    Thanks in advance

    Throw away that book and get another one. Microsoft is the worst possible source for Java, don't bother with it unless you are forced to by your boss at work.

  • XSLT mapping with Java helper classes

    Hi,
    I'm trying to implement a XSLT mapping to convert my request to a specific soap request message format for this I'm calling some methods from a java helper class.

Has any one called any java helper classes with in XSLT mapping, if so I would appreciate if you could help me with this. Here is the code from xsl.

  • Is there a Java utility class to help with data management in a desktop UI?

    Is there a Java utility class to help with data management in a desktop UI?
    I am writing a UI to configure a network device that will be connected to the serial port of the computer while it is being configured. There is no web server or database for my application. The UI has a large number of fields (50+) spread across 16 tabs. I will write the UI in Java FX. It should run inside the browser when launched, and issue commands to the network device through the serial port. A UI has several input fields spread across tabs and one single Submit button. If a field is edited, and the submit button clicked, it issues a command and sends the new datum to the device, retrieves current value and any errors. so if input field has bad data, it is indicated for example, the field has a red border.
    Is there a standard design pattern or Java utility class to accomplish the frequently encountered, 'generic' parts of this scenario? lazy loading, submitting only what fields changed, displaying what fields have errors etc. (I dont want to reinvent the wheel if it is already there). Otherwise I can write such a class and share it back here if it is useful.
    someone recommended JGoodies Bindings for Swing - will this work well and in FX?

    Many thanks for the reply.

  • How can i execute Spaces API in java main class?

    Hi
    I am able to execute Spaces API through portal application. However if i try to execute it in java main class, its throwing an exception
    "SEVERE: java.io.FileNotFoundException: .\config\jps-config.xml (The system cannot find the path specified)"
    oracle.wsm.common.sdk.WSMException: WSM-00145 : Keystore location or path can not be null or empty; it must be configured through JPS configuration or policy configuration override.
    How can i set this path, so that i can execute Spaces API from java main class.
    Need this main class to configure in cron job, to schedule a task.
    Regards

    Hi Daniel
    Currently i have implemented create functionality in my portal application using Spaces API, which is working fine. Now the requirement is, i need to implement a "Cron Job" to schedule a task, which will execute to create space(for example once in a week). Cron job will execute only the main method. So I have created java main class, in which I have used Spaces API to perform create space operation. Then it was giving exception.
    Later I understood the reason, as I am executing the Space API with a simple JSE client, its failing since a simple java program has no idea of default-keystore.jks, jps-config.xml, Security Policy. Hence i have included those details in main class. Now I am getting new error,
    SEVERE: WSM-06303 The method "registerListener" was not called with required permission "oracle.wsm.policyaccess"

  • XSLT Mapping : RFC Lookup using java helper class

    Hi All,
    I am doing RFC Lookup in xslt mapping using java helper class. I have found blog for the same (http://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/05a3d62e-0a01-0010-14bc-adc8efd4ee14) However this blog is very advanced.
    Can anybody help me with step by step approach for the same?
    My basic questions are not answered in the blog as:
    1) where to add the jar file of the java class used in xslt mapping.
    I have added zip file of XSLT mapping in imported archived and using that in mapping.

  • Java Error in RFC Lookup in XSLT Mapping usinf Java helper class

    Hi All,
    I am doing RFC Lookup in XSLT Mapping using Java Helper class.
    The Lookup works fine when called one RFC at a time However my requirement is I want to do 2 Lookups.
    Both Lookups works when done individually however when I call both lookups in one mapping I get following error "javax.xml.transform.TransformerException: DOMSource whose Node is null."
    Following is the code I have written in XSLT for the lookup:
         <xsl:template name="Lookup_1">

    My Question: Am I doing anything wrong? Or Is it possible to call multiple lookups in one XSLT?
    Thanks and Regards,
    Atul

    Hi Atul,
    I had the same problem like you had.
    The main Problem is that with the example code the request variable is created as NodeList object. In XSLT a variable is somekind of a constant and can't be changed. As the request object is empty after the first request the programm fails at the following line:
    Source source = new DOMSource(request.item(0));
    So I've created a workaround for this problem.
    In the call of the template I've put the request as a parameter object at the template call:
    <xsl:with-param name="req">
    <rfc:PLM_EXPLORE_BILL_OF_MATERIAL xmlns:rfc="urn:sap-com:document:sap:rfc:functions">
      <APPLICATION>Z001</APPLICATION>
      <FLAG_NEW_EXPLOSION>X</FLAG_NEW_EXPLOSION>
      <MATERIALNUMBER><xsl:value-of select="value"/></MATERIALNUMBER>
      <PLANT>FSD0</PLANT>
      <VALIDFROM><xsl:value-of select="//Recordset/Row[name='DTM-031']/value"/></VALIDFROM>
      <BOMITEM_DATA/>
    </rfc:PLM_EXPLORE_BILL_OF_MATERIAL>
    </xsl:with-param>
    With this change the request will be provided as a String object and not as a NodeList object.
    Afterwards the RfcLookup.java has to be changed to the following:
    package com.franke.mappings;
    import java.io.ByteArrayInputStream;
    import java.io.ByteArrayOutputStream;
    import java.io.IOException;

  • Java.lang.Class- getFields() results in JVM crash when called through JNI

    From a C++ application, I use Invocation APIs to create a JVM and call some Java methods using JNI
    I get a crash in jvm.dll with EXCEPTION_ACCESS_VIOLATION
    when I try to call "getFields" method of java.lang.Class in order to get the Fields of the java class
    This method call, should return a java/lang/reflect/Fields[] on success
    I am able to get the method ID of this method by using pEnv->GetMethodID(..)
    However, when I call this method using CallObjectMethod(..), HotSpt JVM crashes with access violation with the dump given below.
    Any clues on how to debug and find the problem?
    Or has anyone tried getting the fields of a Java class from C++ by calling reflection APIs uing JNI?
    Thanks in advance!
    Sample code
    jclass testerClass = pEnv->FindClass("com/test/Tester");
    jmethodID cid = pEnv->GetMethodID(testerClass,"<init>","()V");
    if(NULL == cid)
    pEnv->ExceptionDescribe();

    You are right, I tried getting the java.lang.Class reference for the com.test.Tester by calling getClass() on com.test.Tester
    And using this jclass reference for java.lang.Class, I tried getting the method ID of getFields and eventually the Field[]
    Thanks for the help
    I have some more questions.
    Assumption - Using JNI, I got the fields array of com.test.Tester and I am iterating through the fields
    1.Assuming that the Tester class had an Integer field say m_nIntVal, then once I get the jobject equivalent of this Field in C++.
    Now I need to get the type of the field (I call the method java.lang.reflect.getType() from JNI)
    This gives me a jclass reference to it's type i.e java.lang.Integer
    2.I need to get the name of this type i.e I want to get the name of the type in a string as "java.lang.Integer"
    For this, on the jclass reference of java.lang.Integer got in Step 1, I call getClass() from JNI (to get the java.lang.Class) and then getName()
    Now, for calling getClass(), I need a temporary object reference corresponding to the jclass of java.lang.Integer, The problem is that Integer does not have a default constructor, so my call to create the jobject fails.
    But, since I do not know that I am constructing an Integer (remember that is what I am trying to find out - getType), I cant pass any values to constructor
    Now, how do I go about creating a jobject of Integer, without knowing that I am constructing that, as this does not have a default constructor without parameters
    Also, I tried using AllocObject to get the jobject and then tried to get the method ID of getClass(). Even this failed
    3. If the com.test.Tester class had a primitive "int" field, say m_nPrimitiveInt
    for which java provides a Class representation, I am able to get the jclass reference to the type of m_nPrimitiveInt
    Now, how do I get the name of the type as "int" in a string?
    Forllowing a similar procedure like in Step 2 fails when I try to pass the jclass reference to the type of m_nPrimitiveInt to the GetMethodID
    with the error FATAL ERROR in native method: JNI received a class argument that is not a class
    Can you tell me what is the way out?
    Thanks in advance,
    Also, can I mail you with some doubts that I have? If its ok, please contact me at [email protected]

  • Code Sample: Easy RFC Lookup From XSLT Mappings Using a Java Helper Class

    Hi everyone,
    This is just a shameless plug for my article: <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/05a3d62e-0a01-0010-14bc-adc8efd4ee14">Easy RFC Lookup From XSLT Mappings Using a Java Helper Class</a>. I hope you're interested in reading it, and I welcome your comments in this thread.
    Kind regards,
    Thorsten

    Hi Stefan. Thanks for your post. I have already done that. It still does not work. As a base for my java helper class I have usesd Thorstens code.
    The problem is quite confusing. I will try to ouline both issues here.
    First of all, when try to test from within the Operation Mapping, I always get a java error saying it cannot find the communication channel (it is there and working because I have tested it with the RFCLookup in graphical mapping). I have found a way to work around this, and that is to uncheck the "Use SAP XMLToolkit" checkbox --> switch to test tab, enter my ReceiverService in the parameter tab (header parameter) --> switch back to Definition tab, check the "Use SAP XMLToolkit" checkbox --> switch to Test tab and run the test. Then the XSLT and call to java helper class will work. Of course this is not really something you want to do all the time. Maybe there is a bug.
    Secondly, it never works when I try to do it "live". I am using a file adapter to pick up one file, convert it and a file adapter to drop the converted file. I get the following error code in SXMB_MONI.
    <?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
    <!--  Request Message Mapping   -->

      <SAP:Retry>M</SAP:Retry>
      </SAP:Error>
    Using an XSLT without a call to a java helper class, works just fine.
    I am totally at a loss here. Any more input would be much appreciated.

  • RFC lookup with java proxy class, how do I use "fromXml()"?

    Hi,
    I'm trying to do an RFC lookup in XI using java proxy classes (SAP Enterprise Connector).
    The XMLPayload comes from a java proxy class which has been converted to xml using a method called
    .fromXml() for this. I just don't know how to use and I can't find any documentation for it.
    Would very much appreciate if someone could provide me with an example of how to use this class
    Best Regards

  • Intermittent problem in Coldfusion 9, BlazeDS with Java Service class and CFCProxy

    If that title doesn't scare you, you might be able to help.
    I believe there is a bug in Coldfusion 9's version of CFCProxy.
    Tech Stack:
    Flex Application
    BlazeDS (stock with CF9)
    Java Service class (java-amf BlazeDS endpoint)
    Coldfusion business tier, invoked by the Java Service class using CFCProxy
    Tomcat 6 on Java 1.6
    Linux or Windows servers, both exhibit same behavior
    SQL Server database
    Problem:
    When Flex calls a Java service method through BlazeDS that invokes a Coldfusion CFC through CFCProxy, and the method called in the Coldfusion CFC includes a large query (10 fields, 1000+ records returned), we intermittently (1 out of ~5 times) receive the following exception:

    Attempts to diagnose:
    These things remove the problem:
    CF8 works perfectly with the identical code, never fails.
    Calling the same Coldfusion CFC method with the large query (10 fields, 1000+ records returned) from another CFC 100+ times never fails.
    Using a Coldfusion service class (a "my-cfamf" BlazeDS endpoint) never fails. However, we need to use a Java service class because we are using ~40 Java value objects (VOs) that correspond to ~40 auto-generated Actionscript VOs. BlazeDS won't correctly deserialize the Actionscript VOs into the Java VOs with a Coldfusion service class.
    If I replace the large query with a Sleep(5000) instead, it never fails.
    These things don't remove the problem:
    Using the latest Microsoft JDBC driver doesn't help.
    Even if the Coldfusion method returns an empty resultset (i.e., just calls the query and doesn't do any other work or return anything), the call still fails intermittently.
    If the Coldfusion CFC with the method in question is instantiated and stored in SERVER scope as a singleton across multiple requests with CFCProxy, doesn't help.
    Different large (1000+ record queries) all fail in the same way.
    Caching the query doesn't help
    Changes in the datasource configuration doesn't help
    Using the older version of BlazeDS doesn't help
    With all of these tests, I believe it comes down to a problem in the combination between CFCProxy and large queries. There may be more to it, but that is what we've narrowed it down to.
    Any insight would be very welcome.

  • Use java mapping class on PI 7.0

    Hi experts,
    I have a problem with a java mapping class on PI 7.0, maybe somebody could help me.
    I have a java mapping that call a webservice using AXIS library. If I run on my PC the java mapping is working. I load on Imported Archive the Java mapping class and AXIS librarys. My Java mapping class is compilated by jdk 1.4.2.09, like others java mappings that i have on PI 7.0 system, but when I execute the interface, its returns an error:
    Incompatible class versions (linkage error)
    This error is caused by AXIS Libraries, I use AXIS 1.4 version, and I think that this version is using jdk 1.5 because I read it on some foros. Could somebody confirm it? If it is true, could somebody tell me if there are some AXIS version that use jdk 1.4 or maybe How could I solved it? Thanks.
    Regards,
    Gemma

    Incompatible class versions (linkage error)
    this is usually when the jdk version of XI server and the library version you used to develop the mapping are incompatible. Make sure you use the same version as of the server
