Looking for sample java code for dvt:hierarchyViewer

Hi.
We currently use Jdeveloper 11g Build JDEVADF_11.1.1.1.0_GENERIC_090615.0017.5407
Recently, we have seen some nice demos for Manager-Employees tree. Here is one @ http://jdevadf.oracle.com/dvt-faces-demo/faces/dvtTagGuide/ariaXml.jspx?_adf.ctrl-state=mmpgr9aco_4.
If I construct hierarchyViewer from master-detail view objects, I can't achieve dynamic levels. So I believe I need to create a treeModel binding to recursively generate the hierarchy.
Can someone kindly show me a working example for this implementation? Your help is highly appreciated. Now I have to reverse engineer it.

Hi Juan,
Thanks for the quick reply. I already have a similar example http://blogs.oracle.com/shay/2009/07/exploring_the_hierarchy_viewer.html and I made my code work.
However, I realize I must pre-define view objects (and their levels) to achieve this goal. What if I need to use managed bean to dynamically generate the hierarchy? In other words, the level of hierarchy is unknown at run time, the managed bean must be called recursively to generate the next level of nodes.
In the current source code,
<dvt:hierarchyViewer inlineStyle="width:100%;height:600px;" id="hv1"
value="#{bindings.EventsView1. *treeModel* }"
selectionListener="#{bindings.EventsView1. *treeModel* . *makeCurrent* }"
layout="hier_horz_left">
The hierarchyViewer seems to be built around treeModel but the closest I have found is Frank Nimphius's Re: Building a Tree Table using Recursive table
Without recursive calling, i don't think I can get similar hierarchy in http://jdevadf.oracle.com/dvt-faces-demo/faces/dvtTagGuide/ariaXml.jspx?_adf.ctrl-state=rka5d3wx6_9. I have been investigating this for last few days. Correct me if I am wrong :-) Thanks again!

Need Sample java code

Hi,
iam working in SAP .
I need sample java code on how to convert Decimal to number
For Ex: I/p-----123.11
O/p----------------12311 ( with out decimal) want to remove the dicimal point what ever the input value and deliver it to the output
Please give me code
Regards
Suman

i don't know what do you want to do really. If you are doing it simply then you can take the input in a String and then remove the decimal.
String str = "123.11";
str = str.substring(0, str.indexOf("."));
System.out.println(str);

Sample java code to obtain data from ALUI directory

Hi
I need to go to the ALUI LDAP ( directory ) services to get user profile information.
The documentation did not help me to figure out the way to obtain data from it.
so , it would be a great help if some one could share the sample java code api to obtain data from ALUI directory.

i'm guessing you are asking to get the groups for a particular user. someone in the other thread posted the actual SQL, that may be easier. ( you are on 10gR3 right, because ALUI directory didn't exist before 6.5)
I dont have a sample done yet, but the internet is filled with samples of java and ldap...

Sample JAVA code using Resource Adapter for RFC Connections

Hi Java Knowledgeable Ones.
I have successfully deployed the SAP Netweaver J2ee Engine "Resource Adapter for RFC Connections to ABAP Systems" to my Web Application Server. Now I need to develop a JAVA application that would utilize this deployed resource adapter. The resource adapter specifies the SAPClient, UserName, and password. I am thinking that the JAVA code to invoke this connection would therefore not need to provide this information as it should be available in the resource adapter.
Do you have sample code that you could send to me showing how to do this?
Thanks,
Kevin

Hi Kevin,
this is actually no good style! You should not open the connection with the adaptor knowing the password. Usually it should work via a connection that uses only basic rights and the user has already authenticated and is using his security ticket.
For security handling see:

How to compile connection pool sample java code

I recently bought David Knox's "Effective Oracle Database 10g Security by Design", and have been working through his examples with client identifiers and how to leverage database security with anonymous connection pools.
The database side of things I totally understand and have set up, but I now want to compile/run the java code examples, but don't know what is required to compile this.
I'm running Oracle 10.2.0.4 (64-bit) Enterprise Edition on a Linux (RHEL 5) PC. Java version is 1.6.0_20. Relevant .bash_profile environment variables are as follows:
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/jre:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
export PATH=$ORACLE_HOME/bin:$ORACLE_HOME/OPatch:/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin
When I try to compile, I get:
oracle:DB10204$ java FastConnect.java
Exception in thread "main" java.lang.NoClassDefFoundError: FastConnect/java
Caused by: java.lang.ClassNotFoundException: FastConnect.java

Could not find the main class: FastConnect.java. Program will exit.
The java source code of one of the examples is below. Is someone able to point me in the right direction as to how I get this to compile? Do I just have a syntax and/or environment configuration modification to do, or is there more to it than that to get this example working? Any help much appreciated.

I will try to explain what is happening here.
You are launching java telling it to run a class named 'java' in a package named 'FastConnect'
and java says it cannot find that class.
What you intended to do:
$ # make the directory structure match the package structure
$ mkdir OSBD
$ # move the source file in the directory structure so it matches the package structure
$ mv FastConnect.java OSBD/
$ # compile OSBD/FastConnect.java to OSBD/FastConnect.class
$ javac OSBD/FastConnect.java
$ # launch java using the OSBD/FastConnect class
$ java -cp . OSBD.FastConnectNote that the package 'OSBD' does not follow the recommended naming conventions
you might consider changing that to 'osbd'.

Hi,
Each time you perform any SOD Operation after Login, ensure have your JSessionId attached to your actual Web Service URL like in example below
wsLocation ="https://secure-XXXXX.crmondemand.com/Services/Integration";
jsessionId="8d928e8330d53c6f954b16194731bad78f5f111c2043.e34PaxyNchuLe34Rax4SchaKchz0n6jAmljGr5XDqQLvpAe";
String url=wsLocation + ";jsessionid=" + jSessionId;
Use this url for all your future SOD Operation till you logout.

Looking for sample code to create my own pub/sub!

I am a new bee in JMS. So I would really appreciate if
some one could give me some hint to start up with my school project. I am looking for a sample Java code that will:
For the Publisher:
1. Connect to a broker [create it, if it does not exist]
2. Create a publisher/destination.
3. Create a pub-sub queue
4. Publish a message
5. Ack or Nak depending on if the subscriber got or did not get the message.
For the Subscriber:
1. Connect to a broker [create it, if it does not exist]
2. Subscribe to the broker
3. Subscribe to the Queue
4. Show an received messages on the console.
Here are the command line params for both the Publisher and subscriber:
runPub 127.0.0.1:7676 myTestBroker myQueue "this is my message"
runSub 127.0.0.1:7676 myTestBroker myQueue
Please tell me if there are similar java code that will do all this and work with ANY JMS compatible client. i.e. I should not have to use the Admin tool of any JMS Server (MQSeries, iPlanet, SonicMQ etc etc). The code should follow the JMS spec and do this programmatically.
Thank you very very much in advance for doing this great favor.
With regards,
Amir.

Thanks a lot for that hint. I think that's a great tutorial for a beginner. I could compile those sample codes from chapter 4 with out any problem, but could not run it. I also installed j2sdkee1.3.1 and updated my classpath according to the spec. But when I tried to run the "j2ee -verbose" command it was giving me the following error message:
ERROR: Set J2EE_HOME before running this script.
Any advise for me that I should follow next. Thanks again.

Java code for logging from servlet on AS

Hi guys,
I have developed a servlet on SAP AS and I need to log information from processing. Can you please suggest me the best way to do that? I am not an Java expert but when I see the code I'd understand it. Can you please provide some Java logging example code which would work on AS 7.3?
Thanks a lot,
Peter

Hi Peter,
Please have a look of the below logging links/docs
Sample Java Code with Logging - Using Central Development Services - SAP Library
Tracing and Logging - SAPNetWeaver Application Server Java Security Guide - SAP Library
Integrating Third-Party Logging Frameworks into SAP NetWeaver CE
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/20ecb0f4-ccb0-2a10-46aa-ceee8895f34b?QuickLink=index&overridelayout=true&25009594565056
Or
You can simply use System.err.println() or System.out.println()
Thanks,

Logging Not Working in Java Code

Hi everyone,
I'm looking into the Java code for the Portal app, and I'm trying to do some debugging as to what's going on. I see a lot of the Adobe classes use the log4j Logger to output general logging information as well as errors, but there never seems to be any output in the log files. The files I'm checking for activity are:
Adobe LiveCycle ES2\jboss\server\lc_turnkey\log\server.log
Adobe LiveCycle ES2\jboss\bin\correspondencemanagement.log
When I build and deploy the application onto the LC server, just before my application starts I get the following line in the server.log:
2011-04-29 14:30:49,055 INFO [STDOUT] **** No servlet context set in ServletLogTarget - logging disabled.
followed by a message saying that my application has started. The line above happens everytime I re-deploy the application (without actually running the app), right before it starts, so I'm assuming that it is directly related to my application.
The only 'com.adobe' related logging lines that happen in the correspondencemanagement.log file are written when I physically run the app, and I get the following line:
2011-04-29 14:31:34,298 69729 INFO [com.adobe.dct.service.impl.DataDictionaryRegistryServiceImpl] Fetching Complete Data Dictionary object graph.
Looking into the code for the com.adobe.dct.service.impl.DataDictionaryRegistryServiceImpl class, I see it uses a completely different logging system (ie not log4j).
*sigh*
I've changed the services-config.xml file and tried setting the logging target to both flex.messaging.log.ServletLogTarget and flex.messaging.log.ConsoleTarget, but neither seem to make a difference.
I must be missing some kind of configuration to get the logging to work correctly, but Google has been little help as well.
Hopefully someone has crossed this issue before, and has a solution? Any help / pointers / advice etc welcome and appreciated!!!
Thanks,
Kristian

Thanks for the reply Saket.
It turns out that the logging was working correctly all along. The messages I could not find were all related to bootstrap code. I was assuming that the bootstrapper would run each time the application was deployed, or at the very least each time the server was started. It turns out that you manually need to run the bootstrapper. So I was looking for log lines that would never appear by themselves. Once I manually ran the bootstrap process, the log lines ran as expected.
Cheers,
K.

the sample JAVA codes are provided for sending SPML requests, HTTPClient and one more (i dont remember rite now) within the OIM installation folders itself. It's in the 'SampleHttpClient' folder. Check it once. WSDL, sample XML's and the JAVA codes all are there. You just need to set the classpath and run it.

Rendering HTML JSF Component via java code

Hey,
I was wondering,
I want to build sort of HTML generator (for a very specific process),
I thought about taking the advantage of JSF components instead of writing an HTML generator,
Is it possible to render Html JSF Components via simple java class?
For instance, assuming I built an 'HtmlDataTable' object with columns, inputs, etc...
I'd like to render the dataTable as HTML and get the HTML tags via a simple java class,
Thanks.
