How can I make server use single class loader for several applications

I have several web/ejb applications. These applications use some common libraries and should share instances of classes from those libraries.
But applications are being deployed independently thus packaging all them to EAR is not acceptable.
I suppose the problem is that each application uses separate class loader.
How can I make AS use single class loader for a set of applications?
Different applications depend on different libraries so I need a way that will not share library for all applications on the domain but only for some exact applications.
When I placed common jar to *%domain%/lib* - all works. But that jar is shared between all applications on the domain.
When I tried to place common jar to *%domain%/lib/applibs* and specified --libraries* attribute on deploying I got exception
java.lang.ClassCastException: a.FirstDao cannot be cast to a.FirstDaoHere http://download.oracle.com/docs/cd/E19879-01/820-4336/6nfqd2b1t/index.html I read:
If multiple applications or modules refer to the same libraries, classes in those libraries are automatically shared.
This can reduce the memory footprint and allow sharing of static information.Does it mean that classes should be able to be casted ?

You didn't specify which version of the application server you are using, but the config is similar as long as you know what to look for. Basically, you need to change the classloader delegation. Here's how it is done in 8.2

Re: How do you create and use "common" type classes?

Hi,
You have 2 potential solutions in your case :
1- Sub-class TextNullable class of Framework and add your methods in the
sub-class.
This is the way Domain class work. Only Nullable classes are sub-classable.
This is usefull for Data Dictionary.
The code will be located in any partition that uses or references the supplier
plan.
2- Put your add on code on a specific class and instanciate it in your user
classes (client or server).
You could also use interface for a better conception if needed. The code will
also be in any partition that uses or references the supplier plan where your
add on class is located.
If you don't want that code to be on each partition, you could use libraries :
configure as library the utility plan where is your add-on class.
You can find an example of the second case (using a QuickSort class,
GenericArray add-on) with the "QuickSort & List" sample on my personal site

I'm relatively new to forte and I'd like to know how can you handle utility
type classes that you want to use through out your application? Ideally
what I want is a static class with static methods.
Let's say that I have a StringUtil class that has a bunch of methods for
manipulating strings.
My problem is that we have code that runs on the client and code that runs
on the server. Both areas could use the StringUtil class, but from what I
understand, I have to create StringUtil in a plan and then create a server
object of type StringUtil. The server object will eventually get assigned
to a partition. That's not good since I really want the server object to
physically reside at the server end and at the client end. (Actually, I
don't want a server object, I just want to invoke a static method of a
static class).
Any clues on how to solve this problem would be appreciated.

Hi Richard,
Your question about "utility classes" brings up a number of issues, all of
which are important to long-term success with Forte.
There is no such thing as a static method (method that is associated with a
class but without an implicit object reference - this/self/me "pointer") in
TOOL, nor is there such thing as a global method (method not associated
with a class at all). This is in contrast to C++, which has both, and
Java, which has static methods, but not global classes. Frequently, Forte
developers will write code like this:
result, num : double;
// get initial value for num....
tmpDoubleData : DoubleData = new;
tmpDoubleData.DoubleValue = num;
result = tmpDoubleData.Sqrt().DoubleValue;
tmpDoubleData = NIL; // send a hint to the garbage collector
in places where a C++ programmer would write:
double result, num;
// get initial value for num....
result = Math::Sqrt(num);
or a Java programmer would write:
double result, num;
// get initial value for num....
result = Math.sqrt(num);
The result of this is that you end up allocating an extra object now and
then. In practice, this is not a big deal memory-wise. If you have a
server that is getting a lot of hits, or if you are doing some intense
processing, then you could pre-allocate and reuse the data object. Note
that optimization has its own issues, so you should start by allocating
only when you need the object.
If you are looking for a StringUtil class, then you will want to use an
instance of TextData or TextNullable. If you are looking to add methods,
you could subclass from TextNullable, and add methods. Note that you will
still have to instantiate an object and call methods on that object.
The next issue you raise is where the object resides. As long as you do
not have an anchored object, you will always have a copy of an object on a
partition. If you do not pass the object in a call to another partition,
the object never leaves. If you pass the object to another partition, then
the other partition will have its own copy of the object. This means that
the client and the server will have their own copies, which is the effect
you are looking for.
Some developers new to Forte will try to get around the lack of global
methods in TOOL by creating a user-visible service object and then calling
methods on it. If you have a general utility, like string handling, this
is a bad idea, since a service object can reside only on a single
partition.
Summary:
* You may find everything you want in TextData.
* Unless you anchor the object, the instance will reside where you
intuitively expect it.
* To patch over the lack of static methods in TOOL, simply allocate an
instance when required.
Feel free to email me if you have more questions on this.

How to use custom password encryptor/decryptor class for jdbc connection

I am in process of migrating application from Jrun server to weblogic . In jrun we use to provide our custom class which used to decrypt the password provided in resource file as below
<username>webclt</username>
<password>AAAAAAASSSSSSSCCCCCCCCCCCCCC</password>
<encrypted>true</encrypted>
<encryption-class>com.CustomEncryptor</encryption-class>
How could i use the same class while configuring datasource in weblogic 10 server.

1- By default, the jre will read the user's cacerts which runs the program.
2- You can specify another cacerts this way :
System.setProperty("javax.net.ssl.trustStore", my_trust);
For the case 1 and 2, you need to put the certificate in the cacerts.. Or,
3- You implement a custom TrustManager which, for example, accepts all certificates :
class X509TrustManagerTrustAll implements X509TrustManager {
public boolean checkClientTrusted(java.security.cert.X509Certificate[] chain){
return true;
public boolean isServerTrusted(java.security.cert.X509Certificate[] chain){
return true;
public boolean isClientTrusted(java.security.cert.X509Certificate[] chain){
return true;
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return null;
public void checkClientTrusted(java.security.cert.X509Certificate[] chain, String authType) {}
public void checkServerTrusted(java.security.cert.X509Certificate[] chain, String authType) {}
and you call it in the right place in the code you wrote (SSLContext,..)
Hope it helps and deserves a duke star ;)

How to use abap memory in global class

Hi experts,
I want to know how to use abap memory in global class. when i try write export and import statement its showing
error is export statement does not support in object oriented concept.
Thanks

Hi Ramesh,
Export and import statements were not allowed to use in classes. Create a global variable in public section of that class of type of export parameter.Then pass value to the global variable of class by calling that class.

How to use logging in the actions classes extends standart actions?

Hello!
I have some action classes extends standart actions, for example Z_ExtMaintainBasketDispatcherAction extends MaintainBasketDispatcherAction. I tried to use logging functionality in my classes but there were no my lines in log and trace files.
For example I added followed lines in basketPerform() method of Z_ExtMaintainBasketDispatcherAction:
boolean isDebugEnabled = log.isDebugEnabled();
if(isDebugEnabled){
log.debug("++++++++++++++++ Test tracing in B2B_SNG. ++++++++++++++++");
but in there was no such line neither in log file nor in trace file.
How I can use logging functionality in my own classes? I need it for tracing and logging.
CRM 5.0

Well, here is solution. I created a log formatter and log destination like this:
<log-formatters>
<log-formatter name="application_sap.com/crm~b2b" type="TraceFormatter" pattern="%d,%-3p %t %s %l %m"/>
</log-formatters>
<log-destinations>
<log-destination name="application_sap.com_crm.b2b" type="FileLog"
count="10" effective-severity="ALL" limit="10000000" pattern=".\log\applications\isa_ru.log">
<formatter-ref name="application_sap.com/crm~b2b"/>
</log-destination>
</log-destinations>
and new log controller like this:
<log-controller effective-severity="ALL" name="ru.sng.isa">
<associated-destinations>
<destination-ref name="application_sap.com_crm.b2b" association-type="LOG"/>
</associated-destinations>
</log-controller>

How to use a protected attribute of class cl_gui_alv_grid

Hello all,
       i have a scenario where i need to use the attribute 'm_appl_events' which is protected attribute. in need to add this event type into my events and add this to registered events.
    when i tried to use this with refrence to class i defined, it showing an error message 'access to protected attribute m_appl_events is not allowed. i already inherieted the cl_gui_alv_grid class into my class
     can any one please tell me how exactly could i use the protected attribute.
Thanks,
raju N

Hi Krishna,
Protected method or attrubute can be accessed through Inheritence or Friends functionality. So you can inheritence easily in you case . so that you can access the variable in the Inherited sub class only. So you can write 2 methods ie GET or SET ing the value of your protected method.
I think this informatio may help you.
Best Regards,
Vijay

How to use function of an abstract class??

Hi all,
I want to use the format(object obj) function of the package java.text.Format. But as the Format class is an abstract class i could not instantiate it, so that i can call the format(object obj) method using the dot(.) operator.
I know what is an abstract class. i've studied and tried to understand. as everybody knows, studied the perfect example(because i've read it in all the abstract class tutorial, books) of the Shape class. But still i dont understand how am i going to use that format(object obj) method. Please help me..

Instead of using the abstract class Format use the
concrete classes DecimalFormat
SimpleDateFormat etc check java.text APIS
http://java.sun.com/j2se/1.4.2/docs/api
Hi!! Thanks both of you.
If Sun has a abstract class then there must be a
concrete class which extends that abstract class .It
is always better to check the APIWhat do you mean by this line. Is it true for all the abstract classes in the jdk?

How to specify different horizontal restore & collapse icon for af|panelSplitter using Skinning based on Style class or position?

CSS attribute selectors are what you are talking about, but binding the selector with EL is a more-common approach. Using selectors like this require you to ensure browser support.
af|panelSplitter.panelSplitterRighClass::horizontal-collapse-icon [positionedFromEnd=true]

How can I use EntityManager in my pojo class in a JSF web app?

Hi guys,
I need to use EntityManager in my pojo class in a JSF web app. Because pojo is not managed by web container, I cant use resource injection.
Is there any way I do that ? Thanks.

If you want something done fast, then why don't you try reading the API. The API:
a) points your to the Swing tutoral on "Using Text Components" which has a working example
b) shows you 3 ways to load data into the JEditorPane.
