Still got problems with java class business operations

Hi all,
I've read the latest on business operations and java class files, but my problem
remains - the workaround of putting the class file in the studio classpath did
not work for me.
To breifly recap the problem -
I am unable to assign an instance variable when trying to call a predefined business
operation of a java class. Calling the constructor seems to work okay and I can
assign the result to a variable of type "java object" but that's as far as it
goes. If I try placing the class file in the studio classpath, my "Instance Variable"
dropdown list dims, but I am still prompted to choose one when I press okay.
I'm using process integrator 2 sp2 on wls6.
Please help!
Regards
Andrew

Still no good. I'm running my testing on my own PC with windows 2000. Maybe a
windows bug rather than a remote bug?!
Anyone else have a suggestion?

What platform are you running on?
I have found the same problem when trying to run wlpi remotely.
We have a sun box with the WLI installation. When i run wlpi on that
box, and
do the business operation configuration as u describe below, i get instance
variables
populated in the drop down box of the business operation window. I can
then select
the java object my instance is assigned to.
However, when i connect remotely using the studio and try to view the
business
operation settings, nothing appears in the instance drop down box.
When i go back to the console and run the studio on the same machine
as the installation,
the instance variable drop down is populated once again.
So all i can say is, configure the workflow on the machine have the running
installation,
and then it should work. It did for me :)
Hope this helps

  • Help: Still got problems with package

    I still got problems with my self-defined packages. My source files are all put in a directory as the package
    name suggests. The questions are:
    1. Before the classes in the package can be cited by the outside programmes, should I compile
    every sources files in the package respectively?
    2. Secondly, I want to put the .class files in another directory, such as \classes\package name, should
    I set the path mannully? If yes, how to do it?
    3. I downloaded some *.java files from Internet and put them in a directory as their package name suggested.
    However, when I run javac a.java I got error: cannot read a.java. What problem could it be?
    Thanks!

    1. Before the classes in the package can be cited by the outside programmes, should I compile
    every sources files in the package respectively?Yes, you can't run .java files. The JVM only uses the .class files, so you have to compile them.
    2. Secondly, I want to put the .class files in another directory, such as \classes\package name, should
    I set the path mannully? If yes, how to do it?You have to put the .class file in the package directory structure. You have no choice about that.
    3. I downloaded some *.java files from Internet and put them in a directory as their package name
    suggested. You need to read a lot of stuff, but start with this:
    http://java.sun.com/j2se/1.4.2/docs/tooldocs/windows/classpath.html
    However, when I run javac a.java I got error: cannot read a.java. What problem could it
    be?You don't run .java files. You run .class files.

  • Java.io.NotSerializableException when trying to invoke java class Business Operations in studio

    According to WLI docs, the Java Class Business Operations doesn't need to be Serializeable.
    But somehow everytime I try to invoke the Busines Operations in studio, It always
    throws me exception : java.io.NotSerializableException. Is it something wrong
    with my Java Class ? The operation seems to be executed successfully but after
    that It looks like WLI is trying to serialize the object into database which can
    not be done because the Java Class is not serializeable. Changing the Java Class
    to serializeable is not an option since I don't have any control on this class.
    Please advise...
    regards,
    Martin

    Hi Alexander,
    This is a known problem and the workaround for this is to add the classesin the
    classpath of the studio.

  • Problem with java classes

    i have made some java files in java project but when i compile the files
    it gives me error " error 300 : classes are not found "
    <<should the classes be created automatically or i have to create them>>
    i will post more info if necessary

    Are you using an IDE? Are you just starting with Java? If so, it's generally recommended to not start with IDEs because you tend to miss learning about some basic fundamentals.
    As for obvious problems.... I'm not sure these aren't just cuz you posted them here wrong, but I'm not going to assume that...
    If the file is driver.java, the class name has to be driver, not Driver. It's case sensitive. The public class name (I say public cuz you can define multiple classes in one java file) has to have the same name as the java file. So that could cause problems.
    The other thing is what you set up in the CLASSPATH system variable. If you don't know what this is, you should go here:
    http://java.sun.com/docs/books/tutorial/
    and start reading from the begining.

  • Still having problem with java regex

    Hi
    I have the following data in a text file:

    PortName: IP_192.45.10.200
    ServerName:

    I want to print out the string after the word "Name: " in this case it would be "ps1"
    I ve tried it as follow but it does not seem to work:

    String line = null;
    try

    System.out.println( printName );
    else
    System.out.println("line" + line);
    catch (Exception e)
    System.out.println(e);
    Does anyone have a suggestion on how I can get this to work?
    thanks

    Your line has a type: Pattern p =Pattern.compile("Name: (\\w*)");The space should be after ":", not before it.
    This should pick up both Name: ps1 and PortName: something, since you Matcher.find() will find anthing that matches.
    To match only from the beginning of the line, use:Pattern p =Pattern.compile("^Name: (\\w*)");

  • Problem with Java and Windows (Mainly Vista and UAC)

    Hi all,
    I am having a problem with a program that I've devoloped. The program itself is packaged as a jar and I plan to deploy it across multiple platforms eventually however right now i am only concerned about windows based systems. I have made an installer for a windows baised systems using NSIS to install the software files. I made the installer as I need several java packages to be installed so the program would work (JAI, J3D, JAI ImageIO) and I also require the program to have fileassociations on windows.
    I know that this is not what java is about, however the majority of the users will be on windows baised systems so I've decided that OS specific installers is the best option.
    During the process I have noticed that there are several key problem with java for this type of application!
    The first issue that I have come across is getting file associations to work on java. As a .jar is not an excutable it is not possible to directly associate a filetype with it in java so to overcome this I currently run the program from a .bat files and also the program requires large memory so this also allows me to run the program with -xmx. The batch file that I use is :
    <code>
    cd PATH TO PROGRAM
    start javaw -Dsun.java2d.noddraw=true -Xmn100M -Xms500M -Xmx1000M -jar "PATH TO PROGRAM\program.jar" %1 -vram 134217728
    pause;
    </code>
    Ok so all this appears to work fine and allows windows to have file associations and start the program and thats all works perfectly but this is a non-ideal solution. Has anyone got any advice on improving this?
    The next problem that I have appears to be a problem with Vista and UAC (user access control). When a user installs the program and installs the program into the program files directory I found that the program did not work and kept saying that I did not have access to the files in the current directory. This is a problem as I read and write settings files during program execution.
    On a Vista system UAC prevents file write operations into the Program Files directory unless the program has requested elevated status even if the user is a full administrator. The probem is that there appears to be no real way to achieve this under java that I'm aware of...
    Has anyone else had this probem and has a suitable solution?
    Any advice on these issues would realy be appricated.
    Regards
    Joey

    Ok so i've kinda found a solution, its not ideal but its very good. I found this program called Elevate
    A link to the site I got it was
    http://www.wintellect.com/cs/blogs/jrobbins/archive/2007/03/27/elevate-a-process-at-the-command-line-in-vista.aspx
    This program allows you start java with a UAC dialog for high access using
    Elevate java -jar myjar.jar
    This then allows you to have full access using java... I guess it could be dangerous but it does the job.

  • Problems with java j2re using mozilla

    Hi,
    i'm using j2re1.4.2_05 plugin for mozilla in linux (Fedora Core 2). My internet access goes throught a router (SMC Networks ISDN Barricade SMC7301TA). It's settings can be edited throught a web browser LAN connection. And here the problems begin. On routers settings page a java output console (for error and other messages) is running, which doesn't work, despite java applications on other web pages work well (I tested it on sun's java test page and it's working properly). Java console exits the following errorr message:
    >
    load: class DynamicTable.class not found.
    java.lang.ClassNotFoundException: DynamicTable.class
         at sun.applet.AppletClassLoader.findClass(Unknown Source)

         ... 10 more
    Is there a way to fix this problem? Cause without the command output it's mearly unpossible to configure the router.

    Yes i can make changes. Not everything is realised with java, just the output console, which reports if the changes i made succeded, prints out logs, gives additional info about some settings etc. So, i can make changes, but i have no response, for example: everytime i save something i don't know if the save was succesful. I can't take a look at IP routing table and DHCP configuration...
    On windows xp, using internet explorer (the default version for xp) everything works perfect. But mozilla for windows has also problems with java. I know i can still change settings on wins, but right now i'm having some problems with networking on linux and i have to set things up in it (besides i use wins only because of school purposes).

  • Problems with Java DOM Mapping
