Java JNDI Weblogic dependencies and Example

Hello, I'd like help with this scenario:
- Oracle Weblogic 11g (Bea 10.3) in development environment
- JDeveloper 11g
- Oracle Database 11g
With Weblogic Console Administration:
- JNDI Name: jdbc-DATABASESCHEMA1
it connect file to Oracle Database 11g instance to schema DATABASESCHEMA1
Required example:
- Weblogic JAR files required to be imported in java sorcecode to connect with weblogic jdbc-DATABASESCHEMA1
- Way to see port used in Weblogic Serve for connection
- Java code to connect and make this simple SELECT:
SELECT SYSDATE FROM DUAL;
Regards.

I appreciate your reply. I have some
          questions if we go this way:
          1. If we use JNDI and run the modified RMI service
          objects (not EJBs yet) in weblogic server, will we be
          getting the advantages the same way as for the EJBs,
          such as failover using the clustering technology for
          weblogic servers. Or failover only works for things
          running in the EJB container.
          2. If we use JNDI, does weblogic server handle service
          objects pooling? If yes, how. I would like to make
          sure the JNDI way will not perform worse than if we
          run the service objects at the RMI port.
          Thanks,
          Morris

Weblogic.rmi and java.rmi

Hi,
I would like to use weblogic to access a java object on another machine that
is using java.rmi. I am using the java "rmiregistry" on the non weblogic box.>
How can I write a java program that maintains state to that object at weblogic
startup and call it with a weblogic client?
Thanks

Any kind of integration experience with Weblogic JMS and Oracle AQ?

Hi,
In my company I work with java developers who believe in some kind of "holly" database independence I don't understand and as a result my life as a database developer is hell on earth.. Yesterday we again started to discuss, this time where to log, they believe database is slow and prefer logging to filesystem, after some hours finally I could convince them for some operational and reporting needs to use the database and will do this in an asyncronous way whiich they won't get slow. After all I believe the reason for a database is data, this is the place where data lives, and with the correct desing and implementation logging to database would perform better.
I love Oracle features, and know that we paid a lot for this software, so today I started investigating this promised solution. And quickly I found AQ and JMS topics in the documentation :)
After this introduction here is my problem; my company use BEA Weblogic as application server and the java guys want AQ to automatically (but of course with some delay) take their JMS log requests into database tables. Does any one have similar application experience, or any kind of integration experience with Weblogic JMS and Oracle AQ?
Any comments, references, documentation, sample code, url will be most welcomed :)
Thank you very much!

http://www.oracle.com/technology/sample_code/tech/java/web_services/jmsws/NewsQueueEJB.java.html

I wouldn't go as far to say Oracle AQ is out-dated today. However, it is indeed a proprietary technology that did not found much main-stream adoption in the earlier years after its introduction. The advent of JMS made it somewhat more useful (or should I say intriguing, because more people are trying to tie it together with other J2EE technologies), but the Oracle's JMS wrapper classes in aqapi.jar were not feature complete for a long while, so using it outside Oracle's application server was painful, if not impossible. I do agree that the info at the dev2dev's JMS newsgroup or in this forum is highly fragmented, as neither Oracle nor BEA provides an official solution to integrate AQ with WebLogic, so people like us have to learn the technology through experimentation and in a piecemeal fashion.
3 years ago I was literally "playing around" - we had a polling mechanism set up to use triggers to write Oracle data changes into an event table, and had a Java-based daemon to scan that table and publish events as JMS messages to the WebLogic JMS server. This continues to work reliably till today, but I was looking for a solution that has few parts - I wanted to hook up my WebLogic MDB directly to AQ as a foreign JMS provider. Although I was able to get it to work (including XA), there were a few hoops I had to jump through, such as decompiling the Oracle AQjms classes to make them bind to the WebLogic JNDI tree.
One year after that Diptanshu Parui took what I did a giant step further - he extended the Oracle AQjms classes to allow them to be bound to the WebLogic JNDI tree naturally, and he figured out how to use WebLogic JMS messging bridge to re-send single-threaded AQ JMS messages to clustered JMS queues, which allow concurrent message assumption by multiple instances of MDB's. My impression is that he is using that setup in a production environment.
I am sure you are aware of it but I would like to make it clear - in order to use AQ as a foreign JMS provider to WebLogic-hosted MDB's, you don't need to update your database to Oracle 10g - Oracle 8i is good enough (although I recommend at least 9i Release 2). It is not the database engine, but rather the aqapi.jar JMS wrapper on top of AQ that matters. I do recommend that you use aqapi.jar from Oracle Application Server 10.0.3 or up for better XA support, among other things. Again, you don't have to replace WebLogic with Oracle AS - you only need a single jar file from it and put it in your WebLogic's classpath. However, I don't know what this means from a licensing point of view if you ever go to production - do you have to pay the full price of OracleAS or OC4J just to use the aqapi.jar?
In the coming days I will test the latest aqapi.jar to see how much progress Oracle has made in terms of making their J2EE products more spec-compliant :-).
Hope the above gives you a different perspective.

How to identify the installed Weblogic Server and JDK are 32bit or 64bit?

Hi everyone,
I have a question ~
Both Weblogic Server and JAVA JDK are installed on the server already, but I only know the Weblogic Server is 10.3.4.0 and JAVA JDK version is 1.6.0_25.
I know the 64bit Weblogic Server installation file is a wlsXXXX_generic.jar package and 64bit JAVA JDK needed also.
But, since the Weblogic installed already, there are no such installation files on the Linux Server now.
I have tried the "java -version" for java version and check the Weblogic version from Weblogic console.
How to identify the installed Weblogic Server and JDK are 32bit or 64bit with Linux command? Or is there any way to check it?

What you can try to do is use WLST (or an MBean browser, such as JConsole or JRockit Mission Control) and connect to the adminserver.
For example when using WLST:
# set the environment by using setWLSEnv.sh (located in the ${WL_HOME}/server/bin directory).
# start WLST by using: java weblogic.WLST
# connect to the adminserver
connect('adminusername','adminpassword');
# change to the serverruntime environment
serverRuntime();
# show the attributes
ls();
# Here an attribute is shown called WebLogicVersion that shows the version of WebLogic
-r-- WeblogicVersion WebLogic Server 10.3.5.0 Fri Apr 1 20:20:06 PDT 2011 1398638
# Note that this does not show if is 32 bits or 64 bits to retrieve this information you have obtain the JVM version
# change the directory
cd('JVMRuntime/AdminServer');
# show the attributes
ls();
-r-- Version R28.0.1-21-133393-1.6.0_20-20100512-2126-linux-x86_64
# when you have something like x86 at the you are running a 32 bit version, if you have something like x86_64 you are running a 64 bits versionAs mentioned above you can also retrieve this information by using a MBean browser.

Weblogic.rmic and ant integration issue

I am trying to call weblogic.rmic compiler through a ant script and was
sucessful in doing so and generating the stubs and skelton for my RMI

But i also want to pass a system property value (in the example i am passing
file=stdout using -D to java) to weblogic.rmi compiler and don't know how to
do that.
Any help will be greatly appreciated...

As far as I know, rmic doesn't know anything about a "file" system property. Is
there some reason you expect this to do something special?

Java JNDI Search method performance

Hi,
My requirement is i have more than 10 unique values for single a attribute. i need to retrieve all 10 records mathing it from LDAP using Java JNDI. But in LDAP there are more than 100 unique record in LDAP i need only 10 record that mathes my values.
For example the attribute ou in LDAP has 10 unique values. the values could be retrieved in two ways
Method one: Single Search
I could use a single search to LDAP with all the 10 values in filters
and retrieve all the value
Ex:
String filter = "(|(ou=1)(ou=2)(ou=3)(ou=4)(ou=5)(ou=6)(ou=7)(ou=8)(ou=9)(ou=10))";
NamingEnumeration answer = ctx.search(BASE_SEARCH, filter, ctls);
Method Two: Multiple Search
I could use a multiple search to LDAP for each value of ou
Ex:
String[] inputou ={"ou=1","ou=2","ou=3","ou=4","ou=5","ou=6","ou=7","ou=8","ou=9","ou=10"};
int inputSize=inputou.length;
for (int j=0;j<inputSize;j++){
Attributes matchattribs = new BasicAttributes(true);
matchattribs.put(new BasicAttribute("ou", inputou[j]));
NamingEnumeration answer2 = ctx.search(BASE_SEARCH,
matchattribs, returnAttrs);
Query:
which method is more efficient single search or multiple search.
is it efficient to have mutiple search based on one specific ou or it is efficient to have single search with multiple ou using OR clause.
is it less efficient when executing an OR clause and searching with multiple ou.
Thanks

Hi,
They are equivalent becuase second method does not use a filter and for each iteration it creates new mathcing attributtes and executed the search to LDAP. My query is in method one the number of hit to LDAP is one in second method the number of hit to LDAP is 10 based on the number of ou.
I have checked this program and tracked through System.currentTimeMillis() using more than 1000 ou's. the time taken for method one is 3.2306666 mins and the time taken for method two is 4.61735. so it is clear that method one is more efficient in terms of time but still i need more detail answer because some say using OR clause in filter is less efficient than using ou=1.
Thanks

wlst vs java classname="weblogic.WLST" which one is preferred?

Hi,
I have recently started working with weblogic 10gR3 and came across examples to invoke wlst scripts from ANT.
Since there are two approaches i would like to know the difference and which one is preferred. I have so far seen more examples of <java classname="weblogic.WLST"> then <wlst>. In my personal experience i find it more convenient to invoke python script using weblogic.WLST option.
any comments?
thanks
salman

Hello Lance,
I will try to reproduce it on my side and see if I can reproduce, until then use the shutdown() method on the server runtime MBean as workaround.
Thanks,

InterMedia Java Classes for Servlets and JSPs and Netscape

I am using the interMedia Java Classes for Servlets and JSPs to upload and retrieve multimedia data. I have found that it is much more performant in Internet Explorer (5.5) than in Netscape Communicator (4.7). In fact, I cannot upload images larger than 10K at all using netscape. However, the same image can be uploaded into the same application using IE. Is this a known issue?
Thanks in advance.

Hi,
We have successfully uploaded multimedia data in the giga-byte range (Quicktime and AVI files) at the same speed with both the Netscape (4.7n) and MS IE (4.n and 5.n) browsers. One thing we have noticed is that its very important to set the manual proxy settings correctly if you have an environment with a proxy server. If you don't, then uploads can go via the proxy server and, for some reason, that seems to take considerably longer. For example, suppose you are in the www.xyzco.com domain and are connecting to a host named webserver.www.xyzco.com, then specify webserver and webserver.www.xyzco.com (to cover both cases) in the "Do not use proxy servers for..." box in the manual proxy server configuration screen. Also, if you're using a tool such as JDeveloper that uses the host IP address in the debugger environment, then you also need to add the numeric-based (nnn.nnn.nnn.nnn) IP address to this list.
Hope this helps.
In order to better understand the variety of ways in which our customers are using interMedia, we'd be very interested in knowing a little more about your application, the interMedia functionality that you are using, and how you are developing and deploying your application. If you are able to help us, please send a short email message with some information about your application, together with any comments you may have, to the Oracle interMedia Product Manager, Joe Mauro, at [email protected] Thank you!

Capturing weblogic username and password for use in my console extension

Hi,
I have developed a console extension as a war file and it needs to capture the Weblogic username and password so internally it can use the class MBeanServerConnection that needs these during connection. I have therefore created the standard <login-config> <auth-method>FORM</auth-method> ... stuff in the web.xml to output a logon.jsp when my war is accessed in the hope of capturing username and password. My intention is that these would appear in addition to the standard logon that appears when the Weblogic console is 1st accessed.
However, my console extension logon.jsp does not appear and I think it’s because there is only one logon needed and this is when the main Weblogic console is accessed because my console extension is subordinate to the main Weblogic console.
Therefore, how can I get my console extension logon.jsp to appear so I can capture the Weblogic username and password?
Thanks,
Dave.

One approach that might work is to write a look and feel console extension that modifies the console's login jsp (vs trying to have a second login jsp).
http://download.oracle.com/docs/cd/E15523_01/web.1111/e13745/rebrand.htm#i1070459 describes how to write look and feel extensions.
Basically, you instantiate the look and feel extension template, hand-edit login/LoginForm.jsp, then build and deploy the extension.
One tricky part is figuring out how to pre-compile the jsps. Here's part of a build script I've used for look and feel extensions. Let me know if you need a sample look and feel extension.
<project name="sample-look-and-feel" default="build">
<dirname property="this.dir" file="${ant.file.sample-look-and-feel}" />
<property environment="env" />

JMSML - XML Based Mark-Up Language for BEA WebLogic JMS and JMX

          JMSML is a Mark-Up language designed and developed to make Java Messaging Service
          (JMS) and Java Management Extensions (JMX) programming easy by hiding all the
          JMS and JMX Java API complexity behind a few, simple, easy to use XML tags.

Hi,
I finally managed to post a message to ActiveMQ 5.4.2 from WLS 10.3. I created a foreign JMS Server in WLS. I am not sure if you still have this issue, but I was facing this problem and managed to resolve it so posting the reply!
I placed the activemq-all-5.4.2.jar file in WLS server classpath.
The settings I used for the Foreign Server are:
General tab
JNDI Initial Context Factory: org.apache.activemq.jndi.ActiveMQInitialContextFactory
JNDI Connection URL: tcp://localhost:61616
Destinations Tab
Name: TestQueue
Local JNDI Name: TestQueue
Remote JNDI Name: dynamicQueues/TestQueue (I tried with a normal queue, but it didn't work. So used dynamicQueues here. Will try with other queue also)
Connection Factories Tab
Name: AMQConnectionFactory (
Local JNDI Name: AMQConnectionFactory
Remote JNDI Name: ConnectionFactory (This is default name given by Active MQ, you can change by adding names in jndi.properties file and placing it in config folder of ActiveMQ installation. Please check here: http://activemq.apache.org/jndi-support.html)
Using this configuration I was able to post message to ActiveMQ queue from Oracle Service Bus. One more issue to be taken care is that if the message type is not "Text" then the message body was coming as blank in ActiveMQ. So set the message type as "Text" explicitly.

WebLogic JMS and MQ JMS Mix

          I am writing a bean that reads a message from MQ (using MQJMS) and then write it
          onto a WebLogic JMS ( something lika a bridge). However I don't want to use bridge.
          Question/Problem Statement:
          Once I include mq jms jar files in class path. Would that in conflict with WebLogic
          JMS. How do in my program I make sure that it is using the MQ or WLS JMS implementation.
          I can have InitialContext() setup for mq in File and for WebLogic it is WebLogic's
          Initial Context. Thats is the only thing that I can tell in the program.
          Basically, I am trying to see what will make it ( fully qualified JMS Objects
          or what) decide which implmenatation to use.
          Chris


The WebLogic JMS and MQSeries JMS classes won't conflict. Each JMS provider
          provides different classes that implement the same interfaces, so you can
          have a whole bunch of providers in your classpath and things should be OK.
          Most code that's written to the JMS API (including the code inside WLS that
          receives messages for MDBs) gets the JMS "ConnectionFactory" via JNDI, and
          uses that to create the other objects. (It also has to look up the
          "Destination" objects from JNDI.) When you code to the JMS standard only,
          then the only thing that "tells" your program which provider is being used
          is the ConnectionFactory class that you create or get out of JNDI.
          Below is my usual plug for the white paper that helps explain some of this
          stuff:
          http://dev2dev.bea.com/resourcelibrary/whitepapers.jsp?highlight=whitepapers
          Look for "Using foreign JMS provdiesr with WLS".
