ResultList and Container objects

The Java ResultList and Container objects are used in SAP Mapping UDF's ...does anyone know which specific jar files contain these object definitions ?
Thanks,
Rod.

For PI 7.0(3.0) you need the libraries: aii_mt_rt.jar, aii_map_api.jar, aii_utilxi_misc.jar
For PI 7.1 you need the libraries: com.sap.xi.mapping.tool.lib_api.jar, com.sap.xpi.ib.mapping.lib.jar, com.sap.aii.utilxi.server.jar

SCOM 2012 - Use Powershell to put specific server and contained objects into Maintenance Mode

I am still trying to develop what I thought was going to be an easy script, to put a specific server and all it's contained objects into maintenance mode in SCOM 2012.   Not a group, but just one specific server and all it's stuff.
My script to START maintenance mode has two parameters:
1. The FQDN. So for example: server1.contoso.com
2. The amount of minutes to put into maintenance mode
Then it does the following to START maintenance mode:
Import-Module OperationsManager
$Instance = Get-SCOMClassInstance -Name $FQDN
If ($Instance)
$newEnd = ((Get-Date).AddMinutes($minutes))
Start-SCOMMaintenanceMode -Instance $Instance -end $newEnd -Reason "PlannedOther" -Comment "Comments here"
This seems to work from what I can tell. I know that when you schedule maintenance mode manually in SCOM, there is an option to apply to "Selected objects and all their contained objects". I do not know if that is occurring based on
my code above.   But I think that is what I want to happen.   I just want all monitoring and alerting for the specified server to stop.   So if you think I need to change the above code so that it gets all the "contained
objects" please let me know.
The second part, which I know for a fact isn't fully working, is intended to stop maintenance mode for a server.
My script to STOP maintenance mode has only one parameter:
1. The FQDN. So for example: server1.contoso.com
Then it does the following to STOP maintenance mode:
Import-Module OperationsManager
$Instance = Get-SCOMClassInstance -Name $FQDN
If ($Instance)
$MMEntry = Get-SCOMMaintenanceMode -Instance $Instance
If ($MMentry)
#basically sends an end time of 1 minute from when the script is run
$newEnd = ((Get-Date).AddMinutes(1))
Set-SCOMMaintenanceMode -MaintenanceModeEntry $MMEntry -EndTime $NewEnd -Comment "Removing from Maintenance Mode"
This part does seem to work partially.   It does remove the server from maintenance mode. However, I suspect that it's not removing all the "contained objects" from maintenance mode because when I run the script to stop maintenance
mode on a server, the little maintenance mode icon in SCOM does go away but the overall light for the server stays set to "Not Monitored".   It never turns back to the green checkbox and says "Healthy".   When I start
and stop maintenance mode manually I can see that the green Healthy checkbox comes back. But when I try to run my above code to do it via script, it stays at "Not Monitored" instead.
Can someone help me out here? Looking for answers to two questions:
1. Does my Start maintenance mode code look ok? Will that put a server and all it's contained objects into maintenance mode?
2. What do I need to hadd to my Stop maintenance mode code, so that it correctly stops maintenance mode on the server and all its objects and everything starts to be monitored again?
Thanks in advance! Please let me know if you need any more information in order to be able to help me!

Hello, thanks for your response. Unfortunately, it does not appear that the link you provided works.
As far as not including "selected objects and all their contained objects" I am wondering if there is a way for me to tell for sure. One thing I found was that if I run this script and put the server into maintenance mode, then I go into
SCOM and click on Edit Maintenance Mode for that server, it shows me the details.   It has some comment, and my selected reason, based on the code I posted above.   It also DOES have "selected objects and all their contained objects"
selected at top. So it seems to me like it is working correctly, and does contain all the objects.   If you think that 'Edit' screen would be inaccurate for some reason, please let me know. Or if you know of a way for me to check and
confirm, please let me know that as well.
As for REMOVING it from maintenance mode, I did eventually find a line of code that I think works. Here's what my code looks like now:
Import-Module OperationsManager
$Instance = Get-SCOMClassInstance -Name $FQDN
If ($Instance)
$MMEntry = Get-SCOMMaintenanceMode -Instance $Instance If ($MMentry)
$Instance.StopMaintenanceMode([DateTime]::Now.ToUniversalTime(),[Microsoft.EnterpriseManagement.Common.TraversalDepth]::Recursive);
When I use the above code to STOP maintenance mode, the green checkmark does reappear for the server, and everything seems to be being monitored again.   Unlike before, where the maintenance mode icon would go away, but it would never change back
to saying 'Monitored' again. So I think that changing that one line to stop maintenance mode seems to have done the trick.
So I guess my last concern now is just putting in maintenance mode initially, as I was talking about above. If you still think the 'Edit Maintenance Mode' screen is not a good indicator of what my code does, please let me know.

A function containing switch statement and foreach-object loop

Hello Guys
in my testdomain.lab, i have following five OUs in mt test AD structure:
'OUusers', 'OUcomputers','OUservers','OUadministrators','OUhelpdesks'.
i have created following five variables:
$OUusers = 'ou=OUusers,dc=mytestdomain,dc=lab'
$OUcomputers = 'ou=OUcomputers,dc=mytestdomain,dc=lab'and so on
now i have created a function which gets this names as input &
foreach-object creates the related OU.
but the problem is sometimes when i run my function, maybe some of those five OUs
currently exist in AD so this will cause a
terminating error.
so i know i must use switch statement to define conditions like this:
if $OUusers doesn't exist, execute this : new-ADOrganizationalunit $OUusers
if $OUcomputers doesn't exist, execute this : new-ADOrganizationalunit $OUcomputers
and so on...
it's a long time which i am trying to create a
function which contains such switch statement & properly forEach-object loop.
i have studied switch and foreach-object loops , but this scenario is complicated for me & i was unable to get the correct code.
Function createOUs {
# combination of ForEach-Object and Switch statement here
may someone give me the correct
command please?
thanks a lot

Like this:
$CompanyRoot=tha'ou=MyCompany, dc=mytestdomain,dc=lab'
New-ADOrganizationalUnit -Name MyCompany -ErrorAction SilentlyContinue
$ous='Users', 'Computers','Servers','Administrators','Helpdesk'
foreach($ou in $ous){
New-ADOrganizationalUnit -Name $ou -Path $companyroot -ErrorAction SilentlyContinue
¯\_(ツ)_/¯
jrv, That can't be the solution because when you running a command which tries to creates an OU
which already exist in AD, causes a
terminating error which has two caveats:
1- shows red error message on screen
2- stops and doesn't continue to execute next lines of code
Note that -ea silentlycontinue and -ea ignore have no effect on
terminating errors and they cn't hide error messages, also script can't continue.
i examined that.
to get sure, run this function in your test AD & see the result:
function createOUs {
New-ADOrganizationalUnit -Name 'an-existing-ou' -Protected 0 -ea SilentlyContinue # you see that -ea silentlycontinue has no effect here
New-ADOrganizationalUnit -Name '2ndOU' -Protected 0 -ea SilentlyContinue # you see that because the previous error has been a terminating error, command execution has been stopped and this 2nd OU hasn't been creatde
another bad news is ( as i tested), if we query for an Organizational Unit which doesn't exist in AD , it generates a terminating error as well, so again here -ea has no effect.
test this:
PS C:\> Get-ADOrganizationalUnit -identity 'ou=nonesense,dc=yourDomain,dc=lab' -ea ignore
error doesn't disapear ;-)

Difference b/w DATA TYPE and DATA OBJECT & differences b/w TYPE and LIKE

hai
can any one say the differences between Data type and Data Object.
And also differences between TYPE and LIKE
thanks
Gani

hi,
_Data Types and Data Objects_
      Programs work with local program data that is, with byte sequences in the working memory. Byte sequences that belong together are called fields and are characterized by a length, an identity (name), and as a further attribute by a data type. All programming languages have a concept that describes how the contents of a field are interpreted according to the data type.
      In the ABAP type concept, fields are called data objects. Each data object is thus an instance of an abstract data type. There are separate name spaces for data objects and data types. This means that a name can be the name of a data object as well as the name of a data type simultaneously.
Data Types
   As well as occurring as attributes of a data object, data types can also be defined independently. You can then use them later on in conjunction with a data object. The definition of a user-defined data type is based on a set of predefined elementary data types. You can define data types either locally in the declaration part of a program using the TYPESstatement) or globally in the ABAP Dictionary. You can use your own data types to declare data objects or to check the types of parameters in generic operations.
     All programming languages distinguish between various types of data with various uses, such as .. type data for storing or displaying values and numerical data for calculations. The attributes in question are described using data types. You can define, for example, how data is stored in the repository, and how the ABAP statements work with the data.
Data types can be divided into elementary, reference, and complex types.
a. Elementary Types
These are data types of fixed or variable length that are not made up of other types.
The difference between variable length data types and fixed length data types is that the length and the memory space required by data objects of variable length data types can change dynamically during runtime, and that these data types cannot be defined irreversibly while the data object is being declared.
Predefined and User-Defined Elementary Data Types
You can also define your own elementary data types in ABAP using the TYPES statement. You base these on the predefined data types. This determines all of the technical attributes of the new data type. For example, you could define a data type P_2 with two decimal places, based on the predefined data type P. You could then use this new type in your data declarations.
b. Reference Types
Reference types are deep data types that describe reference variables, that is, data objects that contain references. A reference variable can be defined as a component of a complex data object such as a structure or internal table as well as a single field.
c. Complex Data Types
Complex data types are made up of other data types. A distinction is made here between structured types and table types.
Data Objects
      Data objects are the physical units with which ABAP statements work at runtime. The contents of a data object occupy memory space in the program. ABAP statements access these contents by addressing the name of the data object and interpret them according to the data type.. For example, statements can write the contents of data objects in lists or in the database, they can pass them to and receive them from routines, they can change them by assigning new values, and they can compare them in logical expressions.
       Each ABAP data object has a set of technical attributes, which are fully defined at all times when an ABAP program is running (field length, number of decimal places, and data type). You declare data objects either statically in the declaration part of an ABAP program (the most important statement for this is DATA), or dynamically at runtime (for example, when you call procedures). As well as fields in the memory area of the program, the program also treats literals like data objects.
        A data object is a part of the repository whose content can be addressed and interpreted by the program. All data objects must be declared in the ABAP program and are not persistent, meaning that they only exist while the program is being executed. Before you can process persistent data (such as data from a database table or from a sequential file), you must read it into data objects first. Conversely, if you want to retain the contents of a data object beyond the end of the program, you must save it in a persistent form.
Declaring Data Objects
      Apart from the interface parameters of procedures, you declare all of the data objects in an ABAP program or procedure in its declaration part. These declarative statements establish the data type of the object, along with any missing technical attributes. This takes place before the program is actually executed. The technical attributes can then be queried while the program is running.
     The interface parameters of procedures are generated as local data objects, but only when the procedure is actually called. You can define the technical attributes of the interface parameters in the procedure itself. If you do not, they adopt the attributes of the parameters from which they receive their values.
ABAP contains the following kinds of data objects:
a. Literals
Literals are not created by declarative statements. Instead, they exist in the program source code. Like all data objects, they have fixed technical attributes (field length, number of decimal places, data type), but no name. They are therefore referred to as unnamed data objects.
b. Named Data Objects
Data objects that have a name that you can use to address the ABAP program are known as named objects. These can be objects of various types, including text symbols, variables and constants.
Text symbols are pointers to texts in the text pool of the ABAP program. When the program starts, the corresponding data objects are generated from the texts stored in the text pool. They can be addressed using the name of the text symbol.
Variables are data objects whose contents can be changed using ABAP statements. You declare variables using the DATA, CLASS-DATA, STATICS, PARAMETERS, SELECT-OPTIONS, and RANGESstatements.
Constants are data objects whose contents cannot be changed. You declare constants using the CONSTANTSstatement.
c. Anonymous Data Objects
Data objects that cannot be addressed using a name are known as anonymous data objects. They are created using the CREATE DATAstatement and can be addressed using reference variables.
d. System-Defined Data Objects
System-defined data objects do not have to be declared explicitly - they are always available at runtime.
e. Interface Work Areas
Interface work areas are special variables that serve as interfaces between programs, screens, and logical databases. You declare interface work areas using the TABLES and NODESstatements.
What is the difference between Type and Like?
Answer1:
TYPE, you assign datatype directly to the data object while declaring.
LIKE,you assign the datatype of another object to the declaring data object. The datatype is referenced indirectly.
Answer2:
Type is a keyword used to refer to a data type whereas Like is a keyword used to copy the existing properties of already existing data object.
Answer3:
type refers the existing data type
like refers the existing data object

DAO and Domain Object

hi,
Normally when i want to persist a domain object like Customer object to a database, my statements will be below,
// code from my facade
Customer cust = new Customer();
cust.setFirstName("myname");
cust.setLastName("mylastname");
// set another attributes
cust.create();
with this code i have a CustomerPersistence object to handler for create this customer record to a database. Now j2ee have a DAO pattern. So my question is,
1.where is a domain object within DAO pattern? --> because of we can reused domain object.
2.DTO is Domain Object, isn't it?
3.when i look at some articles about DAO, many of it will present in this way
facade -->create DTO --> call DAO (plus something about factory pattern)
i never see something like this
facade --> domain object --> dao
any suggestion?
anurakth
sorry for my english!!

Hi,
I am a bit confused about implementation of the domain model and I wondered if you could help. My main concern is that I am introducing too many layers and data holders into the mix. Here is what I am thinking.
DTO - used to carry data between the presentation and the services layer
Service Class - coordinates the calling of domain objects
Domain Object - models a domain entity, service layer logic specific to this object is to be implemented here.
Data Object - an exact representation of a database table. many to many relationship between domain object and data object.
Hibernate DAO Class - has no properties, just methods used for read and writing the object to the database. It is passed in the Data Object for persistence. Is it wrong that the DAO contains no properties?
Perhaps the domain object will contain each data object it is comprised of. I was originally going to keep calls to DAOs in the Services class (as recommended in http://jroller.com/page/egervari/20050109#how_to_change_services_logic ) but I am thinking that each domain object could expose a save method, and that method would co-ordinate persisting itself to the various tables it is derived from.
Does this sound resonable? I have trouble finding a pattern on the net that clealy defines the Domain Model. I was tempted to map Domain Objects directly to database tables, and simply persist the Domain Object, but this 1-1 relationship may not always hold true.
Thanks.

XPATH - Scope of BPM container objects

Hi,
I have a question.
When we declare container objects in BPM, the scope is mentioned as "Process".
Does this mean that I can use any container objects declared within the process anywhere.
What I am trying to do is, after a SYNC step, I have a ASYNC step. I have to use the response from the SYNC step in the ASYNC step.
The problem is that the interface of SYNC's response differs from ASYNC's request.
So I was wondering if I could mention the XPATH of SYNC's response while doing the receiver determination for ASYNC.
I tried and it does not work. But technically I assume it has to work.
Could someone point out where I am going wrong ( My understanding / Steps that I am following ).
Thank you team.

When you do the mapping outside of BPM (which is recommended anyway)
then you send the sync response directly as async request and do receiver det. and mapping. to the new structure.
when you do mapping and receiver det. inside BPM, you should be able to access all container elements, but I do not have experience with this.

Schema And Schema Objects

MySQL is a database server that can have several 'databases' each with it's own connection params, privileges, users and objects (tables, views etc). Oracle however has the structure of a 'single database' with 'categorized' objects (if I am correct), that is a database with one or more schemas (usually mapping to users) each containing objects (tables, views etc). If I want to build an application on oracle (I am using Oracle XE) that has several subsystems or modules (HR, Finance, Operations etc) and I want the subsystems to have their own boundaries (like their own database in MySQL, or their own schema in Oracle) containing only relevant objects but interconnected by the usage of the application (the application creates value or functionality across these subsystems), how do I go about structuring my database to handle this, since schemas map to users.
Putt another way, since I'll be working with a user account (a schema) can I have schemas within this account / schema to contain objects for the modules. Wherever the 'module schemas' are, how do I interact with them collectively with my login account which I will use as the database connection within the application.
I don't know if this is the best way to go about it, but my project requirement has changed to one that should have clearly defined modules having similar structures in the database that can be scaled up to their own database in a database server or each in it's own database server.

I did not mention this, but I also already tried that without success. Whether 'DEPARTMENT_VIEW' or 'DEPARTMENTVIEW', I still get 'no data found'. I did not expect to succedd with 'DEPARTMENT_VIEW' just like that, because it is the name of the view in the other schema (HR) hence I made the synomyn 'DEPARTMENTVIEW' pointing to it, which hasn't worked either.
I tried this query :
"SELECT table_name FROM user_tab_columns"
I could see only the tables defined in my schema. This makes me wonder how I can run a query against 'USER_TAB_COLUMNS' for a SYNONYM as the table_name, when 'USER_TAB_COLUMNS' has no entry for any of my SYNONYMS in the first place ??
Based on what Ignacio Ruiz said :
'you need to query ALL_SYNONYMS if you want to resolve DEPARTMENTVIEW'I tried this query :
"SELECT table_owner, table_name FROM ALL_SYNONYMS WHERE synonym_name = 'DEPARTMENTVIEW'"
and got the record, but I don't know how to merge this result to a query on 'USER_TAB_COLUMNS' to get the
column_name, data_type, data_length, data_precision, data_scale, nullable etc for the said 'DEPARTMENTVIEW'.
Please what else can I try. Thanks alot.

Jndi and serializable objects

Hi,
I am attempting to create a cache on the web server to store
frequently accessed reference data. I do so by running a series of
queries in a startup class. The data retrieved from the result set of
each query is stored in a custom class and bound to the server context.
My understanding is that when serializable objects are bound, they are
written to disk (so as not.to waste valuable Heap space I assume). As a
test I made the startup query return a large amount of data and I
expected to see the amount of free disk space decrease as the objects
were bound however I did not see this occurring. I examined the memory
usage of the java process with the NT task manager, and the memory usage
was increasing pretty dramatically as the query results were performed
and new objects created to store this data.
Based on these observations I assume that the objects I created and
bound are stored in the Java Heap and not written to disk. Would
Weblogic at some point write these to disk if memory became tight or is
my understanding that binding an object serializes it incorrect?
If it turns out that what I am attempting here consumes a lot of heap
space, I assume that server performance will suffer which is
unacceptable. Would using read-only entity beans be a better solution?
The container could manage this memory more effectively but it would
seem to add a lot of overhead for a simple read only data cache.
Thanks,
Steve Snodgrass

We never write jndi data to the disk. So if you add more objects your are
going to take up more heap space. You should be looking at other
alternatives to implement this.

Infocubes and info objects

Hi guys,
i'm new to BI. can any one differentiate between Infocubes and info objects..
please be a bit specific.....

Hi,
An InfoCube describes (from an analysis point of view) a self-contained dataset, for example, for a business-orientated area. You analyze this dataset in a BEx query.
An InfoCube is a set of relational tables arranged according to the star schema: A large fact table in the middle surrounded by several dimension tables.
Use
InfoCubes are filled with data from one or more InfoSources or other InfoProviders. They are available as InfoProviders for analysis and reporting purposes.
Structure
The data is stored physically in an InfoCube. It consists of a number of InfoObjects that are filled with data from staging. It has the structure of a star schema.
The real-time characteristic can be assigned to an InfoCube. Real-time InfoCubes are used differently to standard InfoCubes.
ODS versus Info-cubes in a typical project scenario
ODS
why we use ods?
why is psa & ods nessasary
InfoObject: Basic building block of BW.. ( Its like a field )
Definition
Business evaluation objects are known in BI as InfoObjects. They are divide into characteristics (for example, customers), key figures (for example, revenue), units (for example, currency, amount unit), time characteristics (for example, fiscal year) and technical characteristics (for example, request number).
Use
InfoObjects are the smallest units of BI. Using InfoObjects, information is mapped in a structured form. This is required for constructing InfoProviders.
InfoObjects with attributes or texts can themselves also be InfoProviders (if in a query).

Ram.

Performance and Sprite objects

I've written an application in Flex 2 that consists of
several accordions containing custom canvas objects, and it is
having performance problems.
I'm running the application within IE 6.0 under Windows 2000.
The application loads an XML file and uses the data to create
custom Sprite objects in the canvases. Each Sprite consists of two
swf images that are loaded using the Loader class, a small
rectangle created by using the Sprite graphics property, and a text
label. In addition, each Sprite is connected to one or more other
Sprites by a line drawn using the Sprite's graphics property. The
Sprites have the capability for being dragged, and for being
highlighted when clicked.
My problem is performance; these Sprites perform slower than
a similiar program that I wrote in ActionScript 2.0. From what I
understand, Flex 2.0, ActionScript 3.0, Flash 9, and the new Sprite
class are supposed to deliver greatly improved performance, but my
new application seems worse than the old one under Flash 7 using
MovieClips. The more Sprites on the screen, the worse the
performance, and the lines seem to contribute to the degradation.
There is way too much code involved to include in this
message, so I'm looking for general info. Is there some basic point
I am missing?
The performance is also degraded when triggering instances of
the Menu and Popup classes. When running the Task Manager during
the application, I've noticed that both Memory Usage and GDI
objects increase whenever I display a Menu or Popup. Both Memory
Usage and GDI objects go up and down, but there is a steady
increase in both metrics as I continue to use Menus and Popups. As
far as I can tell, I am disposing of both types of objects
properly, but it appears that their allocation is remaining in
memory.

UnitOfWorkChangeSet and deleted objects

I would like use the UnitOfWorkChangeSet for auditing changes made to the objects. It seams that the UnitOfWorkChangeSet contains new objects and updated objects, but I cannot find deleted objects. The function UnitOfWorkChangeSet.getDeletedObjects always returns an empty set.
1) How to get deleted objects?
2) Where can I find the best information about usage of the change sets?
3) Can I process the change set after calling the method commit or is it better do it in any SessionEvent method (if so - which method should I use?)?
Thank you in advance for any help
Jan Kostrhun

Hello Jan,
For effeciency reasons the deleted objects are only placed in the UnitOfWorkChangeSet in the case of Cache Coordination (Cache Synchronization). If your application is not configured to use Cache Coordination the deleted objects can be found in unitOfWork.getObjectsDeletedDuringCommit(). Please note that this is an internal method in TopLink that may change in future released.
Accessing the UnitOfWorkChangeSet after you have called commit is fine.

Using Container Object in Java Mapping

Hi All,
I need to use a Container object inside a Java Mapping, just like the one wich is used in the Graphical Mapping.
Here is the scenario:
I have an Interface Mapping with three steps on it.
The first step is a Java Mapping just to put some info in the Container. The second step is a XSLT transformation that uses an XSLT file to transforms from IDOC to xCBL. The third step is another Java Mapping that get the info from the Container and insert in the xCBL.
Does any one knows how to do it inside the Java Mapping Code? We cannot make modifications in the XSLT file because of some internal restrictions.
Thanks,

Hi,
If you make the container variable is a part of your message (input of Java Mapping) then you can access as normal fields.
Just have a look at these discussions-
How to use Container Variable across Maps
xi 3.0 - Using BPM variables in messages
Hope this helps,

Container Object in Java Class

Hello ,
I have a Mapping program using java class type (Java SAX in this case). I need to access some Runtime constants and the mapping trace object.
In message mapping is simple. We can use the container object that is pass to a UDF and the GlobalContainer Object.
But how can I access the Runtime constants and mapping trace without a container object ?.
Any ideas...?
Thanks in advance.
Yuvan D.

in Your java mapping class
you should import import com.sap.aii.mapping.api.*;
public void execute(InputStream input, OutputStream output)
        throws StreamTransformationException {
        AbstractTrace trace = null;
        String RESULT = new String();
        trace =
            (AbstractTrace) param.get(

HashSet get() and contains() methods, by value or reference?

All the tutorials I've seen on HashSets use Strings as the object type. With Strings, it seems the get() and contains() methods work by value, not by reference.
<CODE>
String s1 = "dog";
String s2 = "cat";
String s3 = "dog";
HashSet<String> set = new HashSet<String>();
set.add(s1);
System.out.println(set.contains(s1)); //true;
System.out.println(set.contains(s2)); //false
System.out.println(set.contains(s3)); //true
</CODE>
But when I use a custom object, it works by reference:
<CODE>
MyClass c1 = new MyClass("dog", 1);
MyClass c2 = new MyClass("cat", 1);
MyClass c3 = new MyClass("dog", 2);
MyClass c4 = new MyClass("dog", 1);
HashSet<MyClass> myClassSet = new HashSet<MyClass>();
myClassSet.add(c1);
System.out.println(myClassSet.contains(c1)); //true
System.out.println(myClassSet.contains(c2)); //false
System.out.println(myClassSet.contains(c3)); //false
System.out.println(myClassSet.contains(c4)); //false
</CODE>
("MyClass" is a simple class that holds a String and an int).
Is there any way I can get the set to select by value rather than reference for objects that aren't String?
If so, is it possible that the value test could be customised, so that, for example, the above will return true if the String in MyClass is the same, regardless of the int value?

With Strings, it seems the get() and contains() methods work by value, not by reference.
String s1 = "dog";
String s2 = "cat";

System.out.println(set.contains(s1)); //true;
System.out.println(set.contains(s2)); //false
System.out.println(set.contains(s3)); //true

However, as DrClap pointed out, you've mis-diagnosed the problem:
System.out.println(s1 == s1);
System.out.println(s1 == s2);
System.out.println(s1 == s3));would print out the exact same results.
For an explanation why, Google "Java String pool" or try [url http://stackoverflow.com/questions/3297867/difference-between-string-object-and-string-literal]here.

Using databases and container events?

I'm having trouble finding documents show how one should use databases and listen for container events? I'm using Berkley Java DB. I'll need all my remote object to have access to the database. How do I pass that in? Custom adapters? Also, when Tomcat shuts down I need to close the database, how would this be down? Custom adapters? So I may be answering my own question, but I'm asking cause I really don't see anything in the documentation that points this out. It really looks like I'd be using singletons and factories for this. I could register a Servlet or Servlet Context to listen for Tomcat events, but I figured it couldn't hurt to ask others using Blaze, as I'm very new to it. Thanks.

So how would you tell Blaze to use this? Is there something you put into the config file? My thoughts on all this is to use PicoContainer to manage all services then create an adapter to inject all resources when creating remote objects. But this seems a little heavy if Blaze can do all this for me. The adapter seems like the injection point to me. Is that not what it's used for? Or is using it like that bad practice under Blaze? I've read all I can find on Blaze, so either it's missing docs, or I'm not finding them all. If I'm missing them, by all means let me know where to go. I don't want to ask questions that are already answered in documents else where.

  Using databases and container events?
I think it's mainly in JavaDocs but here's a sample I have where I check to make sure the HSQLDB is running as the BlazeDS starts up:
import java.sql.Connection;
import java.sql.SQLException;
import flex.messaging.config.ConfigMap;
import flex.messaging.services.AbstractBootstrapService;
public class DatabaseCheckService extends AbstractBootstrapService
    // This is called right before server starts up.
    public void initialize(String id, ConfigMap properties)
        Connection c = null;
        try
            // Check that the database is running...
            c = ConnectionHelper.getConnection();
            // ... if yes return
            return;
        catch (SQLException e)
            System.out.println("DB is not running!");
        finally
            ConnectionHelper.close(c);
// This is called as server is starting.
    public void start()
        // No-op
// This is called as server is stopping.
    public void stop()
        // No-op
