O/R mapping tool with WebLogic

Hi
What is the most popular O/R mapping tool used with WebLogic - TopLink? CocoBase?
Anything else?
Also, does anyone have market share numbers for this tool, e.g. out of the total
number of O/R tools used with WebLogic, XYZ's share is 75%.
Thanks in advance!

Andrew,
Hi there. I've performed some research regarding
your question, and it appears that having an
"automatic" 1:1 indirect relationship between an EJB
2.0 Entity Bean and a dependent Java object is not
currently supported by TopLink. Examining the
documentation, this non-support unfortunately isn't
documented. I have entered a feature request on your
behalf so that we might be able to support it in a
future major version of TopLink.
However, there are a couple of alternatives which
you can use:
1) We do support non-indirect 1:1 relationships
between an EJB 2.0 Entity Bean and a dependent Java
object. You could disable indirection, and maybe
make the relationship a batch read relationship so
that your performance will not be degraded.
2) You can write a concrete getter and setter, and
provide an instance variable on the entity bean for
your dependent object of type ValueHolderInterface.
Provide the private getters and setters for set and
get -Holder. Map this normally using TopLink, and
make sure Indirection is specified in the Mapping
Workbench.
IMPORTANT: TopLink will handle the normal
persistence management for this relationship,
however you will need to handle the merging back of
this object yourself (you had to do this in EJB 1.1
in TopLink as well). Luckily there are good docs on
this, and it's covered in detail - look at the
TopLink for WebLogic documentation : Runtime
Considerations > Managing dependent objects.
Personally, I would implement solution 1) with batch
reading on the attribute, because the dependent
object shouldn't be that "big" (otherwise it would
be an entity bean). This is an easier solution,
however you should investigate 2) fully yourself.

Differentiating Between Windows XP and Windows XP Embedded with MAP Tool

Hi All,
I have a customer who has multiple Windows XP Embedded Thinclients. When he runs the MAP tool they show up as Windows XP devices. I have personally not seen this yet since he hasn't shared the MAP data yet but does anyone know if the MPA tool
can differentiate between Windows XP desktops and Windows XP embedded Thinclients or are they all lumped together? Does the MAP tool show for example versioning that might help differentiate? Any help would be greatly appreciated.

When queried by MAP, the WMI service in the Windows XPe machines are reporting back as “Microsoft Windows XP Professional” and since MAP can only report what WMI tells it, that is what shows up in the reports. This is an artifact of Windows XPe because it
starts out as a full version of XP Pro and then each OEM can choose what parts they want to remove, if any. If the OEMs don’t modify the WMI class to show the product as XP Embedded, it will continue to show up with its original description of Windows XP Professional.

Problem with weblogic deployment descriptor tool (DDInit)

Hi,
I'm just playing with weblogic ... following their tutorual but I can't seem to run their deployment descriptor tool:
java weblogic.ant.taskdefs.war.DDinit <folderName> gives me a NoClassDefFoundError.
I have weblogic6.0sp1 installed with an evaluation license which has not yet expired. I have d:\bea\wlserver6.0sp1\lib in mt classpath so weblogic.jar is n there.
When I check out the contents of the weblogic.jar file .. I can't seem to find this tool.
Can anyone give me a clue as to what I am doing wrong?

Here's a link describing the process. If this is what you are doing then your problem may be that 6.0 doesn't support this.

Issue while integrating external LDAP with weblogic

Hi,
i am trying integrating external LDAP (OpenLdap) with weblogic 10.3. I created a provider and provided required credentials and able to see users and group of the LDAP into the weblogic console. I am also able to login in the weblogic console with the users available in the LDAP after assigning the admin role to the ldap group. But i when i see the user's property (by clicking on the user in the admin console) it only shows the tabs for General, Password and Group only. on the other hand if i see the users from DefaultAuthenticator, it shows the Attribute tab apart from the General, Password and Group.
Can anyone let me knwo how can we get the Attribute tab for the Ldap users.
thx,
Ajay

Hi Ajay
By default Weblogic has READ ONLY adapters for any External Security Providers that are configured like any AD Providers. READ ONLY means, you can only read the data from the ldap but not modify it, hence may be its not showing the Attributes tag. For Default Authenticator, see the first paragraph note in Attributes tab, that says the same thing. NOW, may be WLS can atleast show Attributes in READ only format, but it needs some sort of mappings to be defined. Say on Weblogic side, we have like firstName, lastName which on any typical AD will be like sn (surname = lastname), givenname (firstname) etc etc. This mapping is tough to generalize.
One thing for sure is, from Weblogic you cannot modify or edit any attributes for any user in external AD. If you really want to get those attributes, you may need to use some javax.ldap apis or some 3rd party ready to use tools/apis. I remember Weblogic Portal has a facility to configure a xml file that defines attributes mapping and get all attributes for any user. But again thats in Weblogic Portal product and not part of weblogic server.
If you have any SOA Software, they have some utilities for the same.
Thanks

IIS configuration with Weblogic 10gR3

Hi All,
We are using IIS 6.0 as the proxy server in our portal application. The portal server is Weblogic 10gR3. I have followed some documents to configure it. (http://download-llnw.oracle.com/docs/cd/E13222_01/wls/docs103
/plugins/isapi.html). But I am not able to configure that. Can any body help me in configuring IIS server as a proxy server.
Thanks & Regrads

Configure IIS Plug-in with Weblogic Server
1. Make a directory on the IIS box for the plug-in.
For instance: c:\Inetpub\WLS_IIS_Plugin\
2. Copy iisforward.dll and iisproxy.dll to this new directory.
These files are located at:
10.0: \wlserver_10.0\server\plugin\win\32
10.3: \wlserver_10.3\server\plugin\win\32
3. To install iisforward.dll as an ISAPI filter, do the following:
Go to Start->Administrative Tools->Internet Information Services
(IIS) Manager
In the left pane, drill down to the active website
(like "Default Web Site")
Right-click the active website and select Properties
Select the ISAPI Filters tab and press the Add button
Filter name: WLS IIS Plugin
Or whatever you want
Executable: C:\Inetpub\WLS_IIS_Plugin\iisforward.dll
Or whatever path you created
Press OK twice
IIS6 does not allow the iisforward.dll ISAPI Extension to run by default.
To enable:
In the left pane of the Internet Information Services (IIS) Manager,
click on Web Service Extension (located under the computer name)
In the right pane, highlight All Unknown ISAPI Extensions and press
the Allow button
4. To map .wlforward to use iisproxy.dll, do the following:
a. In the left pane, drill down to the active website (like
"Default Web Site")
b. Right-click the active website and select Properties
c. Select Home Directory tab
d. Click the Configuration... button.
e. In the Application Mapping tab, click the Add... button.
a. Executable: C:\Inetpub\WLS_IIS_Plugin\iisproxy.dll
b. Extension: .wlforward
f. Uncheck Verify that file exists
g. IMPORTANT: Ensure .wlforward is not mapped to iisforward.dll.
While this seems intuitive, it is wrong. .wlforward maps to
iisproxy.dll.
h. Press OK three times
i. Exit the IIS Manager MMC console.
5. Create a text file named iisproxy.ini and place it in the plug-in
directory (e.g. c:\Inetpub\WLS_IIS_Plugin\iisproxy.ini)
iisproxy.ini
WebLogicCluster=localhost:7001,localhost:7003
WlForwardPath=/
Debug=ALL
DebugConfigInfo=ON
WLLogFile=c:/temp/iisproxy.log
6. Restart IIS using the following CLI statement: iisreset /restart
7. Use a browser to access IIS. This will 'turn on' the IIS->WLS
ISAPI filter.
8. Relaunch the IIS Manager and check the ISAPI filter tab to ensure
the iisforward.dll is now 'turned on', as evidenced by a green arrow.

Bug in exists() function of XI Graphical Mapping Tool?

Hi!
If I connect a source field with the exists() function in XI Graphical Mapping Tool and the tag exists it returns TRUE, otherwise it returns FALSE, so everything works as expected.
But I have to connect a user-defined function with exists(). The user-defined function will either calculate a value or set Resultset.SUPPRESS.
If there is a value the exits() function returns TRUE, however if Resultset.SUPPRESS is set it does also return TRUE! This looks to me like a bug in exists() function. Shouldn't it always return FALSE if the input is Resultset.SUPPRESS?
Regards, Tanja

Hi Stefan!
> The exists() function checks, if a queue is empty.
> An empty queue is not represented by the
> SUPPRESS value.
> If inside a queue there is a SUPPRESS value, the
> queue is not empty.
Ok, so it's not a bug and the exists() function is working as expected.
> If you want the exist() function after a UDF, provide
> an empty queue, or easier: return the values "true"
> or "false" directly from the UDF.
Yes, that's how I actually solved the problem. The UDF was used at several places where the ResultList.SUPPRESS output was needed. So I copied the UDF and changed it so that the output was TRUE or FALSE instead.

Has anyone used JAAS with WebLogic?

Has anyone used JAAS with Weblogic? I was looking at their example, and I have a bunch of questions about it. Here goes:
Basically the problem is this: the plug-in LoginModule model of JAAS used in WebLogic (with EJB Servers) seems to allow clients to falsely authenticate.
Let me give you a little background on what brought me to this. You can find the WebLogic JAAS example (to which I refer below) in the pdf: http://e-docs.bea.com/wls/docs61/pdf/security.pdf . (I believe you want pages 64-74) WebLogic, I believe goes about this all wrong. They allow the client to use their own LoginModules, as well as CallBackHandlers. This is dangerous, as it allows them to get a reference (in the module) to the LoginContext's Subject and authenticate themselves (i.e. associate a Principal with the subject). As we know from JAAS, the way AccessController checks permissions is by looking at the Principal in the Subject and seeing if that Principal is granted the permission in the "policy" file (or by checking with the Policy class). What it does NOT do, is see if that Subject
has the right to hold that Principal. Rather, it assumes the Subject is authenticated.
So a user who is allowed to use their own Module (as WebLogic's example shows) could do something like:
//THEIR LOGIN MODULE (SOME CODE CUT-OUT FOR BREVITY)
public class BasicModule implements LoginModule
private NameCallback strName;
private PasswordCallback strPass;
private CallbackHandler myCB;
private Subject subj;
         //INITIALIZE THIS MODULE
           public void initialize(Subject subject, CallbackHandler callbackHandler, Map sharedState, Map options)
                  try
                       //SET SUBJECT
                         subj = subject; //NOTE: THIS GIVES YOU REFERENCE
TO LOGIN CONTEXT'S SUBJECT
                                                 // AND ALLOWS YOU TO PASS
IT BACK TO THE LOGIN CONTEXT
                       //SET CALLBACKHANDLERS
                         strName = new NameCallback("Your Name: ");
                         strPass = new PasswordCallback("Password:", false);
                         Callback[] cb = { strName, strPass };
                       //HANDLE THE CALLBACKS
                         callbackHandler.handle(cb);
                  } catch (Exception e) { System.out.println(e); }
     //LOG THE USER IN
       public boolean login() throws LoginException
          //TEST TO SEE IF SUBJECT HOLDS ANYTHING YET
          System.out.println( "PRIOR TO AUTHENTICATION, SUBJECT HOLDS: " +
subj.getPrincipals().size() + " Principals");
          //SUBJECT AUTHENTICATED - BECAUSE SUBJECT NOW HOLDS THE PRINCIPAL
           MyPrincipal m = new MyPrincipal("Admin");
           subj.getPrincipals().add(m);
           return true;
         public boolean commit() throws LoginException
               return true;
    }(Sorry for all that code)
I tested the above code, and it fully associates the Subject (and its principal) with the LoginContext. So my question is, where in the process (and code) can we put the LoginContext and Modules so that a client cannot
do this? With the above example, there is no Security. (a call to: myLoginContext.getSubject().doAs(...) will work)
I think the key here is to understand JAAS's plug-in security model to mean:
(Below are my words)
The point of JAAS is to allow an application to use different ways of authenticating without changing the application's code, but NOT to allow the user to authenticate however they want.
In WebLogic's example, they unfortunately seem to have used the latter understanding, i.e. "allow the user to authenticate however they want."
That, as I think I've shown, is not security. So how do we solve this? We need to put JAAS on the server side (with no direct JAAS client-side), and that includes the LoginModules as well as LoginContext. So for an EJB Server this means that the same internal permission
checking code can be used regardless of whether a client connects through
RMI/RMI-IIOP/JEREMIE (etc). It does NOT mean that the client gets to choose
how they authenticate (except by choosing YOUR set ways).
Before we even deal with a serialized subject, we need to see how JAAS can
even be used on the back-end of an RMI (RMI-IIOP/JEREMIE) application.
I think what needs to be done, is the client needs to have the stubs for our
LoginModule, LoginContext, CallBackHandler, CallBacks. Then they can put
their info into those, and everything is handled server-side. So they may
not even need to send a Subject across anyways (but they may want to as
well).
Please let me know if anyone sees this problem too, or if I am just completely
off track with this one. I think figuring out how to do JAAS as though
everything were local, and then putting RMI (or whatever) on top is the
first thing to tackle.

Mapping tool creates new columns one at a time

Hi All,
I'm using Kodo 3.2.2 with MySql 4.1. I have a fairly large table (over
2million rows) representing one persistent class. I need to add several
new fields to the object, which will require a refresh mapping on the
database to add new columns for the fields.
It seems when I run refresh mapping on the database, Kodo is adding each
new field individually in seperate ALTER TABLE statements, rather than
adding all the columns in one ALTER TABLE statement.
With MySQL and large tables, this can really increase the time required to
refresh the mapping - I've tried with MSSQL and that database must handle
ALTER TABLE commands differently because it doesn't take a fraction of the
time that MySQL takes.
Is this a bug (I doubt it), but rather a feature improvement?
Thoughts?
Thanks,
Brendan

Thanks Abe for the reply - I've been meaning to look at the process of
creating SQL scripts to perform the refresh mappings on our databases.
I'll have a look at this process before we talk contracting!
Thanks,
Brendan
Abe White wrote:
Unfortunately, we don't have any immediate plans to optimize ALTER TABLEsince
it's not a runtime operation, and as you say most DBs don't have a problemwith
it. Also, note that the documentation shows how to get Kodo to create SQL
scripts rather than directly modify the DB; you could easily edit thescripts
Kodo generates to make them more efficient before piping the SQL to MySQLusing
its client app. (Note that Kodo 3.3 introduces the ability to generate SQL
scripts directly from the mapping tool, rather than having to take an extrastep
through the schema tool).
If getting Kodo to combine ALTER statements is important to you, you couldalso
contact [email protected] about contracting us to expedite this work.

Hi Guys,
Getting below error while replication from Source to target. Source table is having NOT NULL Column, but on target replicat process giving error about some NULL value ??
How to overcome this issue, any idea...

The SCRP_CODE column has a NOT NULL constraint. The ORA-01407 error is telling you that you cannot update or set a value for this column to null because of the constraint. This has absolutely nothing to do with an index. You can use a marker/sentinel value in lieu of using NULL. For a numeric field, where everything is positive, a negative value (-1) can be decoded as meaning null. For a character field, a code such as NA can represent NULL.
This also has nothing to do (directly) with GoldenGate failing because of this error. The underlying SQL statement will fail everywhere, regardless of the tool or application. It is not a case of failing only in GoldenGate.

Different mapping tools in the market -- For BPM mapping in XI

Hi All
 I am more intersted in learning the BPM mapping tools(3rd party or any)
 Can any list out the different tools and which are the best ?
 Our company looking forward to implement XI (BPM's) with mapping tools
 Can any help me on this
Regards
Rakesh

Hi Rakesh,
plz have a look to <a href="http://help.sap.com/saphelp_nw04/helpdata/en/14/80243b4a66ae0ce10000000a11402f/frameset.htm">SAP Library: SAP Exchange Infrastructure</a> for understanding XI, BPM and Mappings.
BPM has no special mapping tool. You can use Java, ABAP, XSLT and graphical Mapping (Message Mapping) at XI, for any case - BPM or not. 3rd Party has nothing to do with BPM or Mapping. That means a non SAP system.

Udo

Mapping tools ?

Hi,
Most of my flows are "IDoc -> file" or "file -> Idoc", and I need to manage several transcodification tables for different countries (I prefer a DDIC table to FixValue or Value mapping) and with an amount of Business systems (more than 300).
Before this week, I used Graphical mapping... but with some difficults to manage correctly several levels of IDoc segments. Graphical mapping is easy to use when there are one or two "0...unbound" segments but no more. And you cannot have an easy access to a DDIC (need to use an RFC in BPM).
Since I'm trying to use abap mapping... but with some difficults to manage correctly the creation of an "0..unbound" messages, in order to distribute them to one or several receivers. Abap mapping is esay to use when there is only one receiver (no management before a block "Multiline to single line"; and it is interresting for requests on DDIC tables (very easy). But it seems there is some differences between a testing with tcode "sxi_mapping_test" (thus in foreground ==> easy to debug) and with the execution of the scenario (thus in background ==> difficult to debug).
I don't know yet the XSLT mapping and the Java mapping (a complete one, not a java function inside graph mapping).
Inside XI 3.0, for such flows, is there a mapping tool which is better than the other with IDocs?
Regards.
Mickael.

You can call Java programs from XSLT mapping.
So any lookups you can code in Java and call it from XSLT program.
Below is the link to know more on XSLT Mapping with Java Enhancement.

There are couple of blogs on the same.
Hope it helps,

JnlpDownloadServlet with Weblogic 6.1 - Null Pointer Exception

Hi,
I am using Web Start with Weblogic 6.1 and I keep getting the exception
java.lang.NullPointerException

Web start itself does not even startup !
If I don't use the JnlpDownloadServlet I can get a simple example to work.
The jnlp file I am using is

Any help would be greatly appreciated,

I have exactly the same problem running JBoss 3-Tomcat-4.0.1. After some investigation it seems that the problem is because of dependency on creating File objects using getRealPath()
The problem manifests itself on several places but for instance:
DownloadRequest Constructor:
if(_context != null && !_path.endsWith("/")) {
String s1 = context.getRealPath(path);
File file = new File(s1);
if(file != null && file.exists() && file.isDirectory())
_path += "/";
s1 is null so a nullpointer is thrown. Instead do something like:
if (_context != null && !_path.endsWith("/")) {
String s1 = context.getRealPath(path);
if (s1 != null) {
File file = new File(s1);
if (file.exists() && file.isDirectory())
_path += "/";
But it is harder to fix on other places such as
ResourceCatalog.scanDirectory(String path)
File file = new File(_servletContext.getRealPath(s));
This will faile since getRealPath returns null resulting in a nullpointer exception which will make it impossible to download versioned jars.
The documentation for ServletContext says that getRealPath will return null if the application is packaged in a war file but this is strange since it worked fine for me for running JBoss-2.4.0_Tomcat-3.2.3. Maybe this is new behaviour for the 2.3 servlet spec ( i assume WL 6.1 is also 2.3 compliant)?
