Java.util.Map type return in webservice method

Wonder, how we can return a java.util.Map type from a webservice deployed on a
weblogic 7.x environment..
any input is appreciated.

Thanks Michael. it helps.

Hi Girish,
By definition, a Java object used as a input parameter (or return type)
of a web
service operation, must has a no-arg constructor in order for a Java-based
Web
Service Stack to serialize/deserialize it to/from XML. java.util.Map
is an interface,
so it does not meet this requirement :-)
If your web service operation is just trying to return (or accept) a
hash map
of "arbitrary complex types", I recommend that you consider switching
this to
be an "array of arrays of specific complex types". The reason I say this
is because,
it allows even non-Java consumers to look at the <schema> elements in
your web
services' WSDL, and figure out all the possible "arbitrary complex types"
that
might be in this array. If you envision the consumer getting a box, where
it can
literally contain anything, you can probably see how much more code they
would
need to write, than if they knew the the box contained a box of these,
and a box
of these, and so on, and so on.
Basically, all the "old school" type-safety rules still apply to web
services
computing. If you want web services with descent performance metrics,
you're probably
going to want to keep a lot of the "old school, distributed computing"
practices
in mind, when you design your stuff :-)
That said, WLS 7.0 SP1 does not currently have a "built-in" HashMap codec.
But,
you could create one using the information at:

Java.util.Map to as object

Hi,
I want to get java.util.Map object returned from server-side
on the client-side. I don't know which flex data-type should I use
for that. I tried Array but it dint help. Someone plz help...
Thanks in advance,

You can use a for-in ActionScript loop to examine any
ActionScript Object:
for(var i:String in someObject) {
trace( i+" = "+someObject
Within the loop, i assumes the name of all the public
properties in the given object.

JPA - Columns to java.util.Map

I need to map the columns of a DB table into a java.util.Map object.
Any idea about how to implement this feature?
These are the columns of my table:
| ID | Value01 | Value02 | Value03 | ... | ValueN |I'd like to obtain a bean like this:
public class MyBean {
private String ID;
private Map values;
}I thought I could extend java.util.Map and redefine the get(Object) and put(Object, Object) methods
(I did something like this in java 1.4) but I can't figure it out in 1.5 with JPA

And that is correct - you can't do that cast. Which is what this code is trying to do.

Ask yourself what object is supposed to be the 'Map' in that line of code?
Is it 'actionEvent', 'getComponent()' or 'getAttributes()'?
My guess is that it is the 'getAttributes' that returns a map. Which means you need to cast
actionEvent.getComponent().getAttributes()as a Map. Which means you need to put that entire thing in parentheses so that the cast is performed on it. And then you have to put THAT entire thing in parentheses so you can call the 'get' method on it.
So this is the 'Map'
(Map) (actionEvent.getComponent().getAttributes())And this calls the Maps 'get' method
( (Map) (actionEvent.getComponent().getAttributes()) ).get("test")If you broke the line into pieces and stored each piece in its own variable you would see it. These object types may not be right but should give you the idea.
//( (Map) (actionEvent.getComponent().getAttributes()).get("test") ).get("test")
MyComponent myComponent = (MyComponent) actionEvent.getComponent();
Map myMap = (Map) myComponent.getAttributes();
myMap.get("test");

Message Mapping - java.util.Map

Hi There
I would like to know if there is any way, using java.util.Map map; to get the "data type" field name in a UDF? Passing a constant with the field name would not be practical.. I'm looking for a object oriented process to use in all my mappings.
Also where could I look for the methods I can use in the map trace object?
Regards,
Jan

But I'm still missing the field name..
Let say I have a message mapping going from Field ACB to Field QAZ and a UDF called CheckLen.
In my UDF I'm looking at the incoming field and if it's length is correct. if not I'm writing an entry into a table stating there was an incorrect field but what I can't get is the the field name so I can write to the table "Invalid length on field ACB" The only way to get this field name value is by passing a constant of "ACB" to the UDF and using that. But we have hundreds of MMs so implementing this would be much more difficult than a OOP way..

BEA error: deleteTaskAttributes(int,java.util.Map)

Hello,
I have installed OIM 9100 on BEA with an Oracle Database.
I got the following error message after starting OIM:
<08.07.2008 11.07 Uhr CEST> <Warning> <EJB> <BEA-012034> <The Remote interface method: 'public abstract void com.thortec
h.xl.scheduler.interfaces.SchedulerController.deleteTaskAttributes(int,java.util.Map) throws com.thortech.xl.scheduler.e
xception.SchedulerGenericException,java.rmi.RemoteException' in EJB 'SchedulerController' contains a parameter of type:
'java.util.Map' which is not Serializable. Though the EJB 'SchedulerController' has call-by-reference set to false, this
parameter is not Serializable and hence will be passed by reference. A parameter can be passed using call-by-value only
if the parameter type is Serializable.>
Can anybody help me or tell me what it means?
Thank you,
Matthias

BEA Weblogic normally throws a ton of these errors as it seems like OIM's ideas on what should be passed by reference and what should be passed by value does not play well with Weblogic.
I have been told to ignore these warnings.
Good luck

Java.util.Map and null key

Hi,
For information, according to the implementation, it is possible to put and get a null key when using a map.
The null key can be added and retrieved when using a HashMap, an exception is thrown for a TreeMap.

The documentation for java.util.Map states:
Some map implementations have restrictions on the keys and values they may contain. For example, some implementations prohibit null keys and values, and some have restrictions on the types of their keys. Attempting to insert an ineligible key or value throws an unchecked exception, typically NullPointerException or ClassCastException.The documentation for java.util.TreeMap.put() states:
Throws:
NullPointerException - if the specified key is null and this map uses natural ordering, or its comparator does not permit null keysSo a Map generally may or may not support null keys and/or values and the decision is up to the concrete implementation. TreeMap states that it doesn't support null keys, unless a Comparator is used that permits null keys.

Servlet java.util.Map Help

It's been a while since I have written any code and I am having an issue getting back into it.
I am currently working on creating servlet to pass info from all my forms to my business logic. However, I am having an issue with getting the data. This may be a topic for a different forum, but I figured I would ask here.
I tested out the servlet with the getParameter() method, and I can get the values. However, when I try to use the java.util.Map, I get blank values.
I think the issue may be that I forgot how to use the Map object. Here is my code:
out.println("<html>");
out.println("<head>");
out.println("<title>Servlet CalCartController</title>");
out.println("</head>");
out.println("<body>");
for (int i = 0; i < formParamsMap.size(); i++) {
Map.Entry entry = (Map.Entry) keyValuePairs.next();
String key = (String)entry.getKey();
String value = (String)entry.getValue();
out.println(value);
out.println("<h1>Servlet CalCartController </h1>");
out.println("</body>");
out.println("</html>");

hacktorious wrote:
OK, so if I replace the loop with the following:
String firstName = (String)formParamsMap.get("firstName");
out.println(firstName);
this gives a blank result.If firstName is an actual parameter, it's probably throwing an exception, and you're swallowing it or otherwise not seeing it. I would expect a ClassCastException if the map contained "firstName".

Exposing java.util.Map data as RequiredModelMBean

I'm trying to expose java.util.Map data but I can't quite figure how.
I'd like the management interface to look like it has an attribute that is actually the key of the map.
For example, calling:
mBeanServer.getAttribute(new ObjectName("nomojomofo:type=mapBean"), "fubar");
would get its data from the target object as:
aMap.get("fubar");
Edited by: nomojomofo on Oct 9, 2007 5:31 PM

You can write a DynamicMBean for that:
http://weblogs.java.net/blog/emcmanus/archive/2006/11/a_real_example.html
However you should be aware that most JMX consoles do not expect that the MBeanInfo of a given MBean can change over time.
If the content of your Map is fixed - you won't have any problem.
If it can change over time, you might consider exposing the Map as a single attribute,
for instance, as a CompositeData.

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

Hi,

Java.util.map in a jar?

My applet works on Netscape 6.1 presumably because the java.util.map class has capabilities that I'm using in my applet that isn't in other versions of java.util.map. Since I want to make my applet cross platform, is there any way to include java.util.map in my jar file so that people can use that version instead? Thanks.
Denise

Denise,
I think that will break your license agreement with Sun, so you probably don't want to do that, right? ;)
I think you should try to figure out what the exact cause of your problem is. Off hand, it almost sounds like your applet uses v1.3 api, but your still using the old <Applet> html tag and not the new <Object> tag. Is this right?

Compile error import java.util.map$entry

Hi,
I am trying to compile code which imports the following package
import java.util.Map$Entry.
The error thrown up is : cant resolve symbol Map$Entry. Why is there a $ in the package import path and is there some configuration required to compile the file.
I am not allowed to change the code. Does anyone have an idea on how this problem can be solved.
Thanks and regards
Kumar Vellal

Btw java docs for the interface are available at:
http://java.sun.com/j2se/1.4.2/docs/api/java/util/Map.Entry.html
Changing the import should probably help compile the code, but without changing the import .. need to check. This is just from what i remember now. Lets see if anyone else comments on this.

I've created my own dictionary with dateToSQL() method overridden.
Now it works fine. But it's a kind of strange. Oracle is used often and my
JDBC drivers
are the most recent (at least, from the oracle.com).
Anyway, thank you again.

Patric,
Thank you for response.
We're using Oracle 8.1.7 via OCI driver from Oracle 9.2.
I've already tried 2.4.0 and it works fine there but I've found another
problem there
preventing me from using it. See my post in solarmetric.kodo.betanewsgroup.

That's odd -- what version of Oracle are you using?
Moving to Kodo JDO 2.4.0
(http://www.solarmetric.com/Software/beta/2.4.0) will almost certainly
get rid of this problem, as we use exclusively prepared statements in
it, and therefore pass dates etc. to JDBC as parameters.
But, to get things working with your Oracle database and Kodo JDO 2.3,
you could create your own extension of OracleDictionary and override the
dateToSQL() method to generate the appropriate TO_DATE() syntax. See our
documentation for more details on creating custom database dictionaries.

Not able to pass cyclic XML schema type to a webservice method

I have a webservice method called getData(GetDataDocument
gDoc).
I constructed a request with object (which exactly satisfy
the XML schema def) to call up the getData(). [From my java client
also I did the same; but the java classes have been generated using
apache's xmlBeans; this works fine with the same kind of request].
But the soap request constructed from flex does not get
generated with all the values that I set in the request object.
On further observation, I found out that if the schema
involves cyclic elements, the soap request is not getting
constructed as desired.
My schema def:
<complexType name="PredicateBagType">
<sequence>
<choice>
<element maxOccurs="unbounded" minOccurs="0"
name="PredicateBag" type="tns:PredicateBagType"/>
<element maxOccurs="unbounded" minOccurs="0"
name="BinaryPredicate" type="tns:BinaryPredicateType"/>
<element maxOccurs="unbounded" minOccurs="0"
name="UnaryPredicate" type="tns:UnaryPredicateType"/>
</choice>
</sequence>
<attribute name="contextNode"
type="tns:contextNodeIDType"/>
<attribute default="false" name="negate"
type="boolean"/>
<attribute name="type"
type="tns:PredicateBagTypeType"/>
</complexType>
Note that the PredicateBagType may contain another
PredicateBagType.
I have constructed my request with objects in my flex
application . Though I have set the BinaryPredicate object in my
PredicateBag object, the soap request constructed looks like this
which is not desired
<SOAP-ENV:Envelope xmlns:SOAP-ENV="
http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd="
http://www.w3.org/2001/XMLSchema"
xmlns:xsi="

<SOAP-ENV:Body>
<tns:get_Data maxPrograms="0" personalInfoUse="false"
xmlns:tns="urn:tva:transport:2005">

<tns:RequestedTables>
<tns:Table type="ProgramInformationTable"/>
</tns:RequestedTables>
</tns:get_Data>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>.
If I comment out the PredicateBagType choice in my xsd, the
flex application constructs the soap request looks like this.
<SOAP-ENV:Envelope xmlns:SOAP-ENV="
http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd="
http://www.w3.org/2001/XMLSchema"
xmlns:xsi="

<tns:RequestedTables>
<tns:Table type="ProgramInformationTable"/>
</tns:RequestedTables>
</tns:get_Data>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
This request holds good. But I cannot comment out the
PredicateBagType from my choice. Is this an issue with soap request
construction issue in Flex..?

Yes, <choice> is just "partial" supported in Flex 2 .
