Java.util.list is not Generic type

Hi All,
i am creating ADF Mobile application and i am getting this error while executing following code.
List<String> results = new ArrayList<String>();
Please help me
Thanks

Thanks for your reply. I am getting the error in the code snippet "List<ProcessResponse.ArrayofObjects>". But if I change it to only "List", the error is resolved. But I am not quite sure I should change it, as because the former snippet is getting invoked automatically.I assume you problem occurs in on the mobile side? (ADF Mobile)
If so, are you using 'Web service client and proxy'? This is not supported in ADF Mobile.

Org.exolab.castor.xml.MarshalException:Unable to instantiate java.util.List

Hi,
I am using castor to unmarshal an xml into a java object.
This object has member variables as collections (List).
Even though in the mapping file I used collections attribute of <field> tag and has set it to arraylist, it is still throwing this exception.
After doing a bit of research on this,I found that since UnmarshalHandler uses reflection to create object from xml, it is trying to invoke java.util.List.newInstance() which is causing this problem.
The class which I am trying to unmarshal is an already existing class and I cannot change the type of the member variables to ArrayList from List.
How can it be resolved?

The exception trace is as below :

Non-built-in type contained in a java.util.List creates a SoapFaultException

I have created a web service that utilizes non-built-in types which uses other
non-built-in types...(simplified example follows)
public class MyService {
public
Foo getFoo( String id ) {
Foo foo = ...; // get persisted foo
return foo;
package mypackage;
public class Foo {
java.util.List barList;
public java.util.List getBars() { return barList; }
public void setBars( java.util.List barList ) { this.barList = barList; }
public class Bar {
// some attributes
I autotyped Bar explicitly and had servicegen/service autotype non-built-in data
types for MyService (aka..Foo)
When I execute the test web page...I get the following soap fault exception (Note:
only if the barList contains some Bar objects)

Certain generic types like java.lang.Object, List etc
may not work properly with the test page, because it
is not possible to figure out how the XML data should
look like.
Can you please try it out using a clientgen generated
stub?

Can we define a complex type that is equivalent to java.util.List?

hi everyone
is it possible to define a complexType that is equivalent to java.util.List? all i know now is how to define an array of some type using either <xs:list> for simpleType or the minOccurs and maxOccurs of the element tag. i was wondering if there is way to define something equivalent to a List in java. thanks

Define a sequence of list tems.
<xs:element name="list">
    <xs:complexType>
      <xs:sequence>
        <xs:element name="item" maxOccurs="unbounded" type="xs:string"/>
      </xs:sequence>
    </xs:complexType>
</xs:element>

Model generation error when using java.util.List in JavaBeans

hi there,
when I try to generate model classes from JavaBeans classes,
packed into a JAR the generation process always stops with erros when the Bean class uses a property of type
java.util.List. See my example:
class MyJavaBean{
private java.util.List someMembers;
The error is:
Inspecting relation "MyJavaBean.SomeMembers" for source class "MyJavaBean"
[Warning]:This relation cannot be added as the TargetModelClass is not specified
[Error]: There are one or more relations unresolved. Importing the model without resolvoing the relations might result in erratic output.
Must I use a workaround or does anybody know something about this problem ? Installed: NW SP12
thx,
sabine

Hi Bhavik,
Can you please explain the error which you are getting while importing the model.
Please have a look at this tutorial.
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/webas/webdynpro/tutorial on using ejbs in web dynpro - 20.html

How to display the contents of java.util.list in a frame???

i should use awt only not applet...
i need to display the contents of java.util.list in a frame...
the contents contains rows queried from a oracle database.....
the contents should be displayed similar to how a lable is displayed..
please help me out..
thanks
dinesh

Of course there is something in AWT:
http://java.sun.com/j2se/1.5.0/docs/api/java/awt/List.
htmlagain, if you carefully read the question, he needs a
table to display a JDBC result set. There is no
pre-made table component in AWT.Well, I read that he filled the data into a java.util.List and now wants to display this list. So a List-component should be sufficient. But I might be wrong...

What is the proper and best way to destroy a java.util.List or Array for GC

Hi,
If I have a java.util.List of objects lets say:
List<File> files = new ArrayList();The List contains 1000 file objects. When my class finishes, is it enough to do
files = null;to make GC able to release it from memory?
Cause it seems like I can't do the following:
for(int i = 0; i < extracted_files.size(); i++){
extracted_files.get(i) = null;
}Or should I use this one:
files.clear()What is the proper and best way to do this in order to avoid memory leaks? How about normal Arrays like File[]?

Thanks for the info!
But what if the List is a class variable running in a Web Service for like months without terminating?You mean if the List variable is a member variable of a long-lived object? Then presumably the list needs to live as long as the object does. In the unlikely scenario that the object needs to live on but its list member variable does not, then yes, setting the member to null will be needed to make the list eligible for GC. But I highly doubt this is your situation, and if it is, you probably have a design flaw.
And if the list is referenced only by a local variable, then, as I already said, when the method ends, the variable goes out of scope, and the List is eligible for GC.
Now, a slightly different situation is when the List needs to live a long time, and at some point during its life, you're done using some object that it refers to. In that situation, simply remove the element from the list (or set the element to null if it's an array rather than a list), and then if it's not referenced anywhere else, it can be GCed.
How about Arrays like File[]? Do I need to iterate through the array and null all the objects or is it enough to just null the Array?YOU. DON'T. NEED. TO. HELP. GC. You don't need to set the elements to null, and you most likely don't even need to set the array variable to null.
Also note that only references can be null, not objects.

The import "java.util.scanner" is not vaild

I am experiment with the java.util.scanner API after compiling the code below I received the following error:
The import "java.util.Scanner" is not valid, since it does not name a type in a package.
I declared a string variable should that suffice?
import java.util.Scanner;
public class Echo {
public static void main (String[] args)
String message;
Scanner scan = new Scanner (System.in);
System.out.println ("enter something:");
message = scan.nextLine();
System.out.println ("hey you entered: \"" + message + "\"");
}

Most IDEs let you select and installed JDK for them to use. Check out that IDE's preferences.
Otherwise, start here and learn to do it with a simple text editor or programmer's editor, and the command line.

Pass and access (java.util.List) between appplications

Hi,
I have two classes in separate jars (applications).
How can I print the dataList record fields in the second class?
Thanks
     MySync mySync = new MySync();
     // database records
     // Name, Address, City, Phone
     mySync.setMyList ((java.util.List) dataList);
        mySync.processList();
public class MySync {
     private java.util.List myList;
     public void setMyList((java.util.List) myList) {
          this.myList = myList;
     public void processList() {
          ListIterator itr = this.myList.listIterator();
          while(itr.hasNext()) {
               Object element = itr.next();
               System.println("Name = " + element ???);
}

OK say you had a jverd.jar containing a MySync class which you sent to me as a library for my program,
and I had a jar with a Record class for MySync to process.
How would your MySync class process a java.util.List of Records?For MySync to even compile, either I had to have your jar available when I was writing my code, so I could put it on my classpath for compilation(And of course I'd also need it to execute my unit tests.), OR Record would have to implement some interface (or extend some class, though that would be less likely) that is on my classpath, either because it's part of the core API or because it's from a 3rd party library that we both downloaded.
Or maybe it's all done with reflection, but that's probably not what you want.
Hard to say when you don't provide a concrete explanation of what you're trying to accomplish and an SSCCE to demonstrate it.

Avoid null in java.util.List...?

Dear friends,
Is there any way to avoid null values in java.util.List<E>.....?
Means any special class(in java.util) is available for avoiding null values....?
Thank you

Dear masijade.,

Thank you
boss134I didn't say to open the API docs index, then search for the word List. I said look at the API docs for the interface List. It sill list the Classes that implement it. Look at those Classes, and see if any of the add methods will "prevent null" (as you seem fond of saying). But this is getting to be a little old, so I'll just tell you, no, there isn't. If you absolutely must have one, then, as Darryll suggested extend one of the current list Classes and override add, addAll, and (to be certain) the varying get methods (so that they don't return any null items, if, somehow or another, a null managed to finagle it's way into the List).
Edit: Or, as suggested in the other thread, which is better, implement the interface directly, delegating calls to a "wrapped" List.

The jar for my adapter is place in OIM_HOME/server/JavaTasks .
Inside the code there is a need to read a configuration xml file which is then parsed using org.apache.commons.digester.Digester parser
The xml file is present in the src folder.
The code looks like below:
URL myURL = MyPlugIn.class.getResource("/com/orgname/appname/xyz.xml");
InputStream configFileAsStream = myURL.openStream();
macManager = (MachineManager)digester.parse(configFileAsStream);
This code works fine when I run it on my local machine, but when I deploy it in OIM I get the following exception:
java.util.zip.ZipException: invalid block type
     at java.util.zip.InflaterInputStream.read(InflaterInputStream.java:147)
     at java.util.zip.InflaterInputStream.read(InflaterInputStream.java:105)
     at java.io.FilterInputStream.read(FilterInputStream.java:66)

     at oracle.xml.parser.v2.XMLReader.pushXMLReader(XMLReader.java:240)
     at oracle.xml.parser.v2.XMLParser.parse(XMLParser.java:222)
     at weblogic.xml.jaxp.RegistryXMLReader.parse(RegistryXMLReader.java:173)
     at org.apache.commons.digester.Digester.parse(Digester.java:1765)
Any ideas on why I am getting this exception?
Is there any other way of going about reading files in adapter code? I have tried reading files by specifying absolute as well as relative paths in OIM but was unable to read them in the adapter code. Any pointers will be of great help.. Thanks!

Java.util.ProperyPermission does not work for

Hi again!
I have some problems with a security.policy file. Its content is provided below:
grant{
//Alow the client to connect to any port above 1024
permission java.net.SocketPermission "*:1024-", "connect";
permission java.util.PropertyPermission "user.language", "read, write";
Unfortunately, the java.util.PropertyPermission does not work. I always get the following exception:
java.security.AccessControlException: access denied (java.util.PropertyPermission user.language write)
at java.security.AccessControlContext.checkPermission(AccessControlContext.java:264)
at java.security.AccessController.checkPermission(AccessController.java:427)
at java.lang.SecurityManager.checkPermission(SecurityManager.java:532)

at essex.kkarad.cache.daemon.SimplePopulationStrategy.doPopulate(SimplePopulationStrategy.java:41)
at essex.kkarad.cache.daemon.Populator.run(Populator.java:42)
Is there any problem with the decleration of the premission? Any ideas?

Err, this may come as a shock, but it's because you changed the system clock.
The Timer class works out the absolute time when to next to do something, and when you change the system clock you break that time.
How much are you changing it by?

Error: java.util.map can not be inherited with different arguments

Hi,
I am getting following error while building the source code.
C:\venus\src\com\martquest\messaging\msgio\MqMessageIOObjectCarrier.java:36: java.util.Map cannot be inherited with different arguments: <> and <java.lang.Object,java.lang.Object>

What should I do to resolve this issue?
Thanks

Hi,
I am getting following error while building the
source code.whose source code? If it's yours, you'd better look at where you are defining and using Map. The error code tells you exactly what's wrong.

Java.util.Properties.load() not loading all properties

Hi,
I'm trying to load the following properties into my Properties class. However, Im only able to load SOME properties not ALL (11 to be precise)
This is my properties file :

This is my java code snippet:
~~~~~~~~~~~~~~~~~~~~~~~
     private void loadProperties()
          try
               GDSConfigurationAdapter adapter = new GDSConfigurationAdapter();
               String configurationResource = adapter.getConfigurationPropertiesResource();
               load(loadStream(configurationResource));
               String eventingPropsResource = adapter.getEventingPropertiesResource();
               load(loadStream(eventingPropsResource));
          } catch (IOException e)
               throw new RuntimeException("Could not load GDS/Eventing properties");
     private InputStream loadStream(String propFile) throws IOException
InputStream propStream = ResourceLocator.getResourceAsStream(propFile);
if (propStream == null)
logger.warning("could not find in JAR! Looking in classpath: " + propFile);
propStream = ResourceLocator.getResourceAsStream(propFile);
if (propStream == null)
IOException t = new IOException("Failed to load property file: " + propFile);
logger.throwing(getClass().getName(), "loadProperties", t);
throw t;
return propStream;
Any help will be appreciated.
