TestUnit

Hi everybody,
I'm implementing a new program in Java and i wish to test it by using TestUnit; a test frame for java.
The problem is that I never did that before. Can anybody tell me where can find some documentation/manual about "Using TestUnit".
Thnx,

I don't know much about "TestUnit", but for unit testing the best that I found is JUnit. I would highly recommend it.

Hi Odie,

Extremely low message throughput with MQ 3.6

We performed some load tests to determine maximum throughput of the Sun JMS framework when used in conditions similar to our application.
The achieved throughput is extremely low: around 10 messages / second while we expected around 100. Could you please verify what may be the reason?
We encountered one particular problem: the time of closing JMS producers increases much during the test. Message throughput decreases proportionally. Time periods of other phases of the JMS API usage remain constant. What can be the reason?
detailed information:
Our configuration used:
server machine:
cpu: Intel Celeron 2.8 Ghz
ram: 1GB
os: CentOS release 4.4 (Final), 2.6.9-42.0.3.EL
application server: Sun Java System Application Server Enterprise Edition 8.1 2005Q2 UR2
java version: 1.5.0_04
we use default imqbroker configuration
client machine:
Intel Celeron 2Ghz
ram: 512MB
os: Fedora Core release 3, 2.6.12-1.1381_FC3
java version: 1.4.02
Test description (find attached test unit sources presenting our way of using JMS API):
Load test is performed by running a number of concurrent test units against the JMS broker. Number of units is constant in time. Additionally, every unit test at the end of its life cycle launches another unit to keep long test time perspective.
Each test unit is self-contained. It contains of a producer and a consumer (MessageListener). It sends messages to itself . Also each message unit sleeps for some time to simulate message processing.
Messages are non-persistent, no durable subscriptions are used. All units are using one shared Queue for whole messaging. Message selectors are utilized to guarantee that messages are delivered to intended receiver.
By this test we wanted to determine a maximum value of message throughput for which all messages are delivered successfully and in some reasonable time (say less than 1 minute).
Some variations of test units are possible, e.g. JMS connections and/or sessions can be open/closed for every sent message or shared among multiple producers. But (contrary to our expectations) we encountered no visible differences in message throughput and message delivery time.
Code of test units:

If you go here:
http://www.sun.com/software/solaris/get.jsp
and
1.Check Sun Java Enterprise (or the Sun Java Application Platform Suite),
2.Click Get Download and Media
3. Then select Systems for windows (the bar at the top)
I beleive you can get Message Queue 3.6 SP3 from it, by only installing the Message Queue component.
Note: it is a large download (500 Mb for Application Platform), especially for Sun Java Enterprise...

Ant tools: converter java card - class file not belonging to the package!

Hi
I have another problem with converter. Could you help me please again if you have the time?
I have created a directory when I save the class files generated by javac. After That , I use convert in this way:
<convert
JCA="true"
EXP="true"
CAP="true"
packagename="testUn/classes/testUn"
packageaid="0x01:0x01:0x01:0x01:0x01:0x01:0x01:0x01:0x02:0x00"
majorminorversion="1.0"
verbose = "true">

<classpath refid="classpath"/>
</convert>
Here is the answer of the computer:
[echo] Generation of the CAP,JCA and EXP files...

I do not understand why this unique applet class file does not belong to its own package. Is someone an idea?

WebServer does not update parameter and looses objects

- Please struggle through my loooong explanation - THANKS
Hi all,
I've got a problem with my servlets/JSPs.
I try to build a homepage where the content is displayed dynamically and the start-page is for each link the same.
The content of the pages are stored in HTMLs and XMLs --> the HTMLs contain the static content and also contains identifier for the XMLs which contain the dynamic content. Problem is, that there can be more than one XML. So I've cretaed a properties-file which maps 1-HTML to n-XMLs. So I've generated code which parses (with SAX) through the XMLs and takes the information and stores these information to an object. This object itself is stored with an ID in a hashmap.
Then I go through the HTML (read in a String) and replace the keys (HTML) with the matching value from the Hashmap.
When a page is displayed and the client clicks on a link the same page should be called with parameter http://..../start?lang=de&page=link then I should get the information and the HTML for the "link".
- When I call the "start"-page the first time it is displayed correct. But when I refresh the page it seems as if an object is lost - the information of the Hashmap (which is stored in another object) is lost. I cannot get the information although I got the information before.
Also the parameters are not updated if I change them, there is always the same exception shown, that the key is not available.
I've also changed the parameters (for lang) and just displayed them. But they did not change...
- I'm absolutely helpless

Thanks for help, in advance,

Since you didn't post the XML parser class, I'm not sure exactly what your problem is but I see lots of things that should be changed.
First of all, get rid of the empty Service() method. Fortunately, you named it wrong so it isn't overriding the service() method in the HttpServlet class. If it were overriding the service() method, your servlet wouldn't even work the first time since there would be nothing to invoke doGet().
You shouldn't be using instance variables for processing requests (i.e. mLanguage, mIdentifier) because your servlet needs to be thread-safe. Essentially, there is usually one instance of your servlet around (this is up to the application server) and that one instance must be capable of handling multiple requests simalteously. This isn't causing your problem right now because you are just testing but once the application goes live, this will be a big problem.
Now for what might be causing your problem. Since you didn't post the XML parsers, I suspect that they might be leaving the files open so the second time through, it can't do the parsing. Anyway, your design isn't right because you seem to be reparsing the XML files for each request. All servlets can have an init() method which is invoked when the application server first loads the servlet. You should do all your XML parsing in the init() method. This is much more efficient since it will only be done once (usually when the application server first starts up) not each time the user requests a page. The only potential drawback to this is if you frequently add new XML files, you will have to recycle the server to get the servlet to pick up the new files.

Remote Deployment permissions

Hi all,
I want to do a remote deployment from my pc to a cluster on different machines using the admin_client.jar file.
The example in the OC4J Deployment Guide is this :
java -jar admin_client.jar
deployer:oc4j:opmn://test-cycle.oracle.com/testunit
oc4jadmin_ welcome1+
-deploy
-file d:\temp\rupg\testru.ear
-deploymentName testru –bindAllWebApps
As you can see the example uses the oc4jadmin account to do a remote deployment.
That also works for me. However, when I use another test account that is not a member of the oc4j-administrators+ role (see system-jazn-data.xml) I get the following error:
+FINER: RMIConnection.writeDisconnectMessage Preparing to send disconnect message: Login failed Not authorized*+
FINE: RMIClient.lookup Failed during lookupjavax.naming.AuthenticationException: Not authorized
at oracle.oc4j.rmi.ClientRmiTransport.connectToServer(ClientRmiTransport.java:100)
+...+
I already tried making the test account a member of the oc4j-app-administrators+ role. This gives the test account only com.evermind.server.rmi.RMIPermission Login.
However, a -validateURI or -deploy using the admin_client.jar still failes.
So my question is : Is there a list available somewhere of all the (jazn) permissions needed to do a remote deployment ? I couldn't find such a list in the deployment guide (10.1.3.4.0) ...
Regards,
Ronald Wouters

I found a solution to this problem.
The problem was that I was trying to do a remote deploy NOT to the default "home" oc4j instance but to another oc4j instance that I created in the same application server instance. I had given my test user only "RMIPermission login". However, this test user was defined only in the system-jazn-data.xml of the "home" oc4j instance.
I simply copied this xml over to the other oc4j instance, thereby setting up the same users, roles and permissions in the new oc4j instance as in the home instance.
After restarting the appserver, remote deployment using my test account worked just fine.
I'm pretty sure this is not the "official" way to do this because in a production environment you would probably not even have write permissions to the directory containing these xml files.
Can anyone tell me if the javasso stuff that I read about in the config and admin manual could be the "official" way to solve this kind of problem ? Or am I way off base here ?
Any insight would be much appreciated.
Regards.

}These are the locations:
Test Module: src/test/resources/META-INF/persistence.xml
Anyway, this is the first approximation of the solution, because what I hope to do eventually is to run the test: the file is copied persistence.xml of ejb module to test module, and modify the lines that indicate it is a jta congiruarción a local configuration.
have suggestions
Thanks!
Felipe

A little reasoning time.
- you have a META-INF/persistence.xml file
- this persistence.xml file contains a persistence unit 'unitTest'
- yet the code still reports that this persistent unit cannot be found
My conclusion right now is that the file is actually not on the test classpath. Do you perhaps have a conflicting test resources setup in your maven pom? The file must somehow be excluded if it is not found.

CAF Datasource

Hi all,
When we develop a new BusinessObject (Local Persistence) the CAF uses the database of system. Does anybody knows if is possible to specify a DataSource to CAF uses?
I'm thinking about High Availability environment, if i have the following scenario:
SAP Web Dispatcher and server1, server2 and server3, with each server with the CAF Application deployed the database will be created for each one, and it isn't desired. How to says to CAF uses the specific datasource that points to single Database server?
Its a good practice change the persistence.xml of CAF ejbmodule project:
- Default-
<?xml version="1.0"?>
<persistence version="1.0">

Hi Isaias,
Since CAF uses Portal database, you must just to configure your portals to use a central (commom) database.
Check this useful (old) document:

Java ServiceUnavailableException with iPlanet

Hi,
There is a piece of Java code like that:
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "ldap://"+hostname+":389/");
env.put(Context.SECURITY_PRINCIPAL, "cn=Directory Manager");
env.put(Context.SECURITY_CREDENTIALS, "password");
ctx = new InitialDirContext(env);
NamingEnumeration names = null;
SearchControls sc = new SearchControls();
sc.setSearchScope(SearchControls.SUBTREE_SCOPE);
for (i=0;i<1000;i++){
names = ctx.search(" ou=TestUnit, ou=domain.com,
o=NetscapeRoot","objectclass=*",sc);
For some reason a javax.naming.ServiceUnavailableException is thrown
sometimes while executing the loop with no visible reason. Does anyone know
why it happens? iPlanet server is located on remote machine and accessed
through network. OS is HP-UX 11.0
Thanks in advance.

You are either running out of available threads to handle the requests
on your directory server or your network connection is failing you.
Check that your ldap server has sufficient connections to handle your
requests. You might need to tune your directory server and increase the
number of concurrent requests it can handle.
But also make sure your network is not causing you problems. It could be
your network is overloaded as well.
