  • EXCEPTION_ACCESS_VIOLATION (0xc0000005) on compiled Java code

    I'm confronted with the following error of this code.
    http://db-www.naist.jp/~makoto-y/tmp/Int2LongHash.java
    The exception appears only when the system gets high-load.
    Is there work-arounds?
    I've tried also with jdk1.5.0_06, but the same error occurred.
    Converting the inner class to a top-level class has no effects.

  • Error while running compiled java code

    Hi
    I have an evaluation license of the JDeveloper2.0 installed on my WindowsNT 4.0 workstation.
    I seem to have a problem running my compiled jave code. After compiling the source code(.java file) when I try to run the same I get a message saying
    "<FileName> not found in outpath classpath or sourcepath ".
    What does this mean and how can I rectify it?
    Regards
    Sree
    null

    Your classpath tells Java run time where to look for the class files it needs. In JDeveloper the class path is set in your project properties. Select Project->Properties and check that the source and output paths correspond to your myprojects and myclasses directories.

  • How to check for a logic bomb in compiled java code ?

    I have couple of security requirements.
    1. How do I check for logic bomb in the compiled java code ?
    2. Is there any way to monitor memory utilized by class when running inside a constructor ?

    1. Let me see if you can define 'logic bomb', then maybe a answer can be supplied. If you simply mean malicious code, then in general you cannot. You can attempt to do the kinds of things that antivirus software does, like check for the existence of known malicious code and code patterns, but that won't work any better on Java than it does on anything else.
    2. Google java profiling. Also, for something relatively simple, read about jconsole.

  • Help required in compiling Java Code.

    I have java1.6 installed on my PC but I want to compile my code in such a way that
    it will run on PCs with lower versions of java installed.
    I am not using any feature specific to java1.6 in my program.

    Im not 100% sure of this but I would of thought a program will compile on any version of java as long as you dont use classes that are exclusive to higher version of java
    for example i would think if you comiled the helloworld tutorial on v.1.6 it will run on computers with lower versions.
    However a program which uses the scanner class (i think exclusive to 1.6 or 1.5 not sure though) will not run on say 1.2
    CalypsoIve tested to run an complied class(version 1.6) on an computer with jre 1.5 installed(before), and it doesnt work. Dont remember precisly the error but it didnt run atleast.

  • Compiling Java code with Japanese characters

    I have a Java code with some Japanese characters. My compiler doesn't recognise these characters and gives me error messages.

    Obviously it's not the copmiler's fault. You need to fix your code.
    Here is a link to the Java Language Specification.
    The link is to section 3.8 - Identifiers.
    It describes the acceptable naming:

  • First time compiling java codes

    Sirs,
    I am able to compile my codes but when I try to execute them
    the message below is shown....
    java.lang.NoSuchMethodError
    How do I fix it ? Thank you all

    The complete error was
    java.lang.NoSuchMethodError: main
    Exception in thread "main" Exit code: 1
    There were errors
    Then the class you are trying to run:
    java [-cp [i]classpath] ThisClass
    (let's assume it is named ThisClass)
    does not have the required:
    public static void main(String[] args)
    method implemented, as already pointed out earlier.

  • Still having problems compiling java code

    I still dont know what is wrong, it works just fine in JCreator but, when I try to use the command prompt it still gives me the same error message. Also I have made sure that the code is in the same directory with the command.

    Thanks for the advice Kitty, that was the command I
    was using javac <FileName.java>. I did, however,
    update my classpath and the path variables like you
    mentioned, but I am still recieving the same error
    message. I just cannot figure out where the error in
    the code is. =(Okay... apparently you need a little help...
    So to help you clarify thing a bit...
    Let's start here...
    This error below...
    C:\myfolder\test>javac VariableDemo.java
    'javac' is not recognized as an internal or external command,
    operable program or batch file.... is what you get if the OS does not know the path to javac.exe...
    if you type path at the command prompt you will see what your "System" path is, which would include an entry that would point to you sdk, something like "C:\YourJavaSDKFolder\bin";C:\someotherprogramfolder;
    This path has nothing to do with the classpath. Your system uses this path to find executables to run you programs ( although many are locations are actually in your registry an therefore no path entry is needed... i.e. MS Word )...
    This error...
    C:\myfolder\test>javac VariableDemo.java
    error: cannot read: VariableDemo.java
    1 errormeans that your compiler was not able to locate your *.java file. I was able to replicate because VariableDemo.java does not exist on my machine, so javac.exe naturally could not find the *.java file...
    javac.exe does not check the "System" path to find class files, so even though you saved you file in your "bin" folder of the SDK, javac would not know it there...
    the way that javac.exe is able to find you class files is either by the default "." as stated before which is your current working directory
    ( noted by your command prompt ... C:\myfolder\test> )
    or if you had specified your classpath either as an argument...
    C:\>javac -classpath c:\myfolder\test VariableDemo.javaor by setting the "classpath" environment variable either temporarily in you command prompt by typing
    set classpath=c:\myfolder\testor setting as you "System" environment variable by ( assuming Win XP though it similar for NT and 2000 ) via System Properties|Advance Tab|Environment Variable... Read your OS documentation for details involving setting your Environment Variable...
    as for why JCreator or what ever IDE you are using is able to do it, is because, part of what it does is temporarily pass the classpath information to the compiler automatically... so that you won't need to do it... and which is why IDE are generally not recommended to beginners to learn Java... It does to much stuff you... hence you classpath issue...
    anyway, check out the links provided for you for further and more detail information on setting the "classpath" on other Java basic...

  • Problem in compiling java code

    Hi,
    I have class (say A) which has an inner class (say B). There is a method(say m1) in A which has a return type as a Vector (say v1). The skeletal of the code is as :-
    public class A {
    public A (String mesg) {
    System.out.println(mesg);
    //inner class B starts
    public class B {
    public String name;
    public int age;
    public B (String name, int age) {
    this.name = name;
    this.age = age;
    //inner class B ends
    public final Vector m1 (String code) {
    Vector v1 = new Vector();
    B b;
    if (code.equals("1111")) {
    b = new B("Tutty",26);
    v1.addElement(b);
    return v1;
    public final String m2 (B b1) {
    return b1.name;
    public final int m3 (B b1) {
    return b1.age;
    // end of class A
    The above class is called in the following code :-
    public class check{
    public static void main(String args[]) {
    A a1 = new A1("Hello");
    Vector v = new Vector();
    v = a1.m1("1111");
    for (int i=0; i<=v.size(); i++) {
    String name = a1.m2(v.elementAt(i));
    //end of class check
    When i compile the above class check.java , i get the following error:-
    check.java:15: m2(A.B) in A cannot be applied to (java.lang.Object)
    String name = a1.m2(v.elementAt(i));
    ^
    1 error
    Kindly help me in rectifying the error.
    Thanks in advance.

    Hi,
    Thanks for the re-designed code.
    But i think if i tell you what exactly we are aiming at, may be you can give us some better and a compact solution.
    We are writing some classes which are based upon entities like student, department etc etc. The return type of the various methods in these classes was becoming a debatable issue, esp. when the output was in the form of an m by n matrix...basically of 'm' columns ('m' fields of the table which was queried) and 'n' rows(records). Out of the various options, we decided that we pass every single record (of the result set) as an object (which will be non-interpretable by the programmer using our class) in a single vector.
    Speaking in an elaborate way, if the query fired was like "show departments with code and name", the output was :-
    "select deptcode,deptname from dept order by deptcode";
    deptcode deptname
    01 Chemical Enginnering
    02 Computer Engineering
    (etc etc)
    Now we decided to pass the above as :-
    Vector v1 = new Vector();
    and to ' v1' we didn't want to add the string as it is but the object of the record like
    v1.addElement ( objectOf(01 and Chemical Engineering) );
    v1.addElement ( objectOf(02 and Computer Engineering) );
    Now this 'objectOf' was upto us to decide.
    So we decided that it can be an object of some inner class (in our case B). But now we realised that we have to reveal the class B also to others (during the A.B casting). So is there a way we can keep this 'objectOf' just to ourselves and when the programmer asks for 'getDeptCode(objectOf(01 and Chemical Engineering))', we have our method to interpret the argument passed and then pass the department code.
    I hope i have not bugged much and made myself clear. I am sure the doubt may be silly, but we have still not come down to any solution and hence we seek help/suggestions.
    thanks,
    Asmita.

  • Running a java program in another java code

    Hello,
    I have a question.I wrote a java server code named server.java. In this server code, I receive another java class code called "HelloWorld.class" from another node. What I want to do is to execute the class HelloWorld inside server.java.
    Briefly, I would like to run a compiled java code (class code)in another executing class code. How can I achieve this?
    Thanks in advance

    Hi,
    Sorry but your terminology isn't that clear. Are you trying:
    1. To call methods on another class or
    2. To launch a separate process that will run another class?
    If it's either of these then they're not 'Advanced Language Topics' but simple:
    // Scenario 1
    // in Server class
    HelloWorld hw = new HelloWorld();
    hw.sayHello(); // or whatever the method is
    // Scenario 2
    Runtime.exec(new String [] {"java", "HelloWorld"}); // or whateverIs that of any help?

  • Compiling *.java for cfinvoke

    I'm trying to connect to a web service that uses
    complex-within-complex data types for its parameter.
    I am constantly getting errors trying to invoke the web
    service and it has been recommended by someone on this list (Mr.
    Andreyev) that I do the following:
    1. Use wsdl2java tool (CF_HOME/runtime/bin) supplying URL to
    webservice WSDL to create java code.
    2. Create java classes by compiling java code created in step
    1
    3. Create jar file(s) from classes in step 2
    4. Put jar file in CF classpath or just copy it to
    CF_HOME/lib directory
    5. Using <cfscript> create required objects, arrays and
    other arguments and supply them to web service method call.
    This is not as simple as it sounds (well, not to someone
    who's only interaction with java is in a cup).
    1. Use wsdl2java tool (CF_HOME/runtime/bin) tsupplying URL to
    webservice WSDL to create java code.
    This has been done. The tool created a series of subfolders
    under C:\CFusionMX7\runtime\bin which ends in a folder called
    schema
    Inside schema are six other folders that each contain 1 and
    111 .java files
    [EDIT] I think I have part of the problem worked out.
    2. Create java classes by compiling java code created in step
    1
    This has not been done.
    My command line in javac is: javac @filename -verbose -source
    1.4
    I get a total of 100 errors and 33 warnings
    All the errors are on this theme:
    C:\CFusionMX7\runtime\bin\...\AccommodationRoomT
    ype.java:10: package org.apache.axis.encoding does not exist
    public class AccommodationRoomType implements
    java.io.Serializable, org.apache.
    axis.encoding.SimpleType {
    The common theme in the error messages is:
    package org.apache.axis.something does not exist
    Am I not using javac correctly or is it just battling to
    compile the code generated by wsdl2java?
    Thanks

    Hi there Mr. Andreyev
    [EDIT]. You are a prince amongst men, sir. All .class files
    have been created
    This version of your line worked
    javac -source 1.4 -deprecation -classpath
    C:/CFusionMX7/lib/axis.jar;C:/CFusionMX7/lib/xml-apis.jar;C:/CFusionMX7/lib/saaj.jar;C:/C FusionMX7//lib/jaxrpc.jar;.
    @C:/CFusionMX7/runtime/bin/au/com/qantas/www/schema/allfiles.txt
    It threw
    warnings, not
    errors. I was reading them as the same thing.
    Thank you for your kind assistance. On to step 3!
    [END EDIT]
    Using the command line as you suggested threw up a new set of
    errors but I think I know what is causing them.
    The first time I tried your script I modified it as follows:
    javac -deprecation -classpath
    C:/CFusionMX7/lib/axis.jar;C:/CFusionMX7/lib/xml-apis.jar;C:/CFusionMX7/lib/saaj.jar;C:/C FusionMX7//lib/jaxrpc.jar;.
    C:/CFusionMX7/runtime/bin/au/com/qantas/www/schema/aCalypsoV1/*.java
    Note that there is a space between the period (.) and the
    start of the path to the java files.
    On running this i received back many many error messages
    pointing out that
    "as of release 5, 'enum' is a keyword, and may not be used as
    an identifier (use -source 1.4 or lower to use 'enum' as an
    identifier)"
    I then modified your line as follows
    javac -source 1.4 -deprecation -classpath
    C:/CFusionMX7/lib/axis.jar;C:/CFusionMX7/lib/xml-apis.jar;C:/CFusionMX7/lib/saaj.jar;C:/C FusionMX7//lib/jaxrpc.jar;.
    C:/CFusionMX7/runtime/bin/au/com/qantas/www/schema/aCalypsoV1/*.java
    This also gave me a bunch of errors in the vein of:
    "C:\CFusionMX7\runtime\bin\au\com\qantas\www\schema\aCalypsoV1\ContactDetails.jav
    a:38: package au.com.qantas.www.schema.CustomersV1 does not
    exist
    public void
    setEmailAddress(au.com.qantas.www.schema.CustomersV1.EmailAddres
    s emailAddress) {"
    The .java files that were created by wsdl2java were grouped
    into six folders under /www/schema
    Every error message references one of these other folders. It
    looks like the compiler is trying to reference them.
    I have these folders:
    www/schema/aCalypsoV1
    www/schema/AmadeusBookingsV1
    www/schema/ChannelsV1
    www/schema/CustomersV1
    www/schema/FinancialsV1
    www/schema/ReferenceV1
    I tried creating a text file with an absolute path to every
    single .java file in those six files in it (naming it
    www/schema/allfiles.txt) and modifying your script as follows:
    javac -source 1.4 -deprecation -classpath
    C:/CFusionMX7/lib/axis.jar;C:/CFusionMX7/lib/xml-apis.jar;C:/CFusionMX7/lib/saaj.jar;C:/C FusionMX7//lib/jaxrpc.jar;.
    @C:/CFusionMX7/runtime/bin/au/com/qantas/www/schema/allfiles.txt
    This threw a set of errors in this theme
    C:\CFusionMX7\runtime\bin\au\com\qantas\www\schema\ChannelsV1\Channel.java:32:
