Pure Java Glassfish

A newbie question:
what will be the first glassfish release to be pure java compliant (eg: not limited to SunOS, Linux or MacOS). V2 final release or V3 ?
Glassfish fits well for what we have to do (stateful session beans), but we have to do it on HP-UX ...

I assume you use LB's FDQN name (am.example.com) as your certificate's CN. You should be having the hostnames of AMs as am1.example.com, am2.example.com respectively. You would have placed the certificate of am.example.com in both the boxes. At some point of time one of the AM instances need to contact the other one for session validation, because it is a load balanced environment. Moreover user's session and agent's session might not be in the same AM instance always. During this time it has to do a session validation with the other one. When doing session validation the requestor AM will not go through the LB, rather it will directly reach out to the other AM instance. Say AM1 is contacting AM2 for session validation. So AM1 will use the hostname as am2.example.com to hit AM2. But in AM2 you have the certificate placed in the name of LB (am.example.com). Obviously AM2 will not accept this request as the hostname and the certifcate's CN is different. I understand you have turned trustAllServerCerts to true in AMConfig, but in 7.1 it will not work as expected. I guess you would have installed AM7.1 as a WAR file deployment. If you go to product support they would insist you to re-install the AM through JES package. Because according to them this parameter (trustAllServerCerts) will be evaluated correctly if you have AM installed by JES. Though I don't fully agree with this solution, this is the suggested one from support. Even though if you re-install AM with JES and enable trustAllServerCerts, then that is not the recommended solution for production. Because enabling this parameter to true is a security risk, especially if you interact with external applications.
So as an alternative you could try using "SubjectAltNames" for your certificates. Include FQDNs of both AM instances in the certificate and add it in the keystore. This will work.
Good luck and let me know the result.

How to run a pure java application client with ear deployed on 9ias

Hello all,
We want to run a pure java application client which is packed with target bean in the same ear file. In the application-client.xml we refer to some EJBs.
We deployed the ear file which contains ejb jar module and application client module to oracle 9ias 904 through enterprise manager on unix. The jndi.properties we used looks like this
java.naming.factory.initial=com.evermind.server.rmi.ApplciationClientInitialContextFactory
java.naming.provider.url=opmn:ormi://opmn_host:opmn_port:oc4j_instance_name/application_name
java.naming.security.principal=test
java.naming.security.credentials=test
Is there anybody knows how to run such an application client? Do we need to provide such a jndi.properties or not at all?
Thanks,
9ias user

     }

Create the object of InitialContest class. Then pass in hashTable put WLContextFactory.
then lookup to the sessionJNDI. then call the create method u will get the remote object, from the remote object u can call to the business method

JVM 1.4 seg faults with pure java code?

Has anybody else seen JVM 1.4 seg fault when running pure java code? This seems like it shouldn't be possible, but I get the following at indeterminate times. Unfortunately, it is difficult to isolate since decreasing the size of the program avoids the problem. When the seg fault happens, the size in memory is ~1GB and there is plenty of real and virtual memory to spare.

Hi sevenM,
Did you figure out a workaround for this problem?. Did you get it solved with the SUN people?. Is it a known bug?.
I've got exactly the same problem on the same function and VM library.
Any info on this is very much welcome.
Thx
Krithiga
I get the same error sometimes with tomcat-4.0.4 on a
Slackware 8.0.0 and JDK 1.4.0. I don't user any JSPs,
only servlets and the business calls a remote SLSB on
a remote JBOSS server and afterwards select some data
form a remote DB2 7.1 over JDBC.
Here is the log:

Is There A Pure Java Solution?

Is there a pure Java solution for a servlet to create
a popup window? In other words, is there a Java solution
for creating a new window with Java code inside the
doPost() method?

Try setting
response.setContentType("text/html");
response.setStatus(HttpServletResponse.SC_PARTIAL_CONTENT);
and stream html with javascript to pop a window. Don't have code right now...but try to search in this direction. Sure you can do...I will post the code if I find..

How to deploy a pure jave development component to server?

i have created a pure java development component.
but i cannot find a way to deploy it to server
is there any way?

You need to essencially wrap your java development component with a deployable development component.
In order to do that, you need to:
- Define a public part for your development component of type assembly.
- Create a deployable DC ( one that results in a SDA or a EAR file ).
- Reference your DC from the deployable DC. This will include the generated .jar file into the project.
The definitions of the different types can be found here:
http://help.sap.com/saphelp_nw04/helpdata/en/93/d5a73f05c4265de10000000a114084/content.htm
I would either create a library component ( results in SDA ) or a web dynpro component ( ear file ).

Generate a thumbnail from HTML by pure Java on Linux without Graphics

hi - we in a requirement where we have to generate thumbnails from HTML code. The solution must be implemented in pure Java on Linux where there is no graphics support.
Options tried already are :--
1. 3rd party websites - rolled out by our client.
2. Paid products - rolled out by our client
3. Media Tracker and other java API - no luck as there is no support after HTML 4.0
4. Using any os dependent native library - rolled out by our client.
5. Lobo browser - but having troubles like it opens the browser before screenshot is taken, sometimes. Gone through by putting Thread.sleep() in between and saving remote images into a local html file etc. We got some success in there but problem doesn't end here.
Questions -
1. In the point # 5 above, our Linux server had graphics support but in code we set the system property java.awt.headless= true before capturing and generating thumbnail. My question is, if we set this property in the code then does it mean 100% that our code will not use any graphics support, if present in the underlying OS?
2. Is this really possible to generate images in java on Linux where there is no X window/X server installed? Are we just wasting time in order to achieve which is unachievable?
Any suggestions are most welcome.
Regards,
Sanjeev

Thanks for ur response! Yeah - we tried but requirements are little different. We have HTML that we have to first render. Whatever output comes, we have to take a screenshot. So in order to render the html we have to have a browser first and I believe every OS which is providing browser support is having Graphics capabilities because browser would have frames, windows, toolbars, menubars etc which fall under Graphics.
The above way is the only way that I know. If there are another way which ofcourse doesn't require graphics support, please let me know.
So the question basically is - if I follow above mentioned image (like opening browser and capture screenshot) then is it possible on Linux with no graphics support? Actually I read on internet that lobo browser (written in java) supports this kind of feature.

Could not load mediaLib accelerator wrapper classes. Continuing in pure Jav

Can anyone provide an explanation/solution to the following error message:
"Could not load mediaLib accelerator wrapper classes. Continuing in pure Java mode."

This problem seems to occur if only the JAI JAR files are installed without the native DLL's. Is there some property that can be passed in to JAI so that it doesn't look for the DLL's? The lookup is causing quite a delay in initial server response time. We don't want to include the DLL's since they are a big pain for our customers to install and the performance issue is not a concern.
Thanks for any help!

Log4j doesn't create backup files in web-app, the same code in pure java ap

Hi all,
in my application I have a class DummyLogger, which is a superclass to all others. It provides them a log4j Logger.
In the constructor it sets up the important attributes:
log = Logger.getLogger(name+" (" + app + ") ");
log.setLevel(Level.toLevel(level));
PatternLayout defaultLayout = new PatternLayout("%p %c,line %L,%d{dd.MM.yyyy/HH:mm:ss},%m%n");
RollingFileAppender rollingFileAppender = new RollingFileAppender();
rollingFileAppender.setName(name);
rollingFileAppender.setFile(path+app+".log", true, false, 0);
rollingFileAppender.setMaxFileSize("10MB");
rollingFileAppender.setMaxBackupIndex(5);
rollingFileAppender.setLayout(defaultLayout);
log.removeAllAppenders();
log.addAppender(rollingFileAppender);
log.setAdditivity(false);Formerly I had the application as a pure java app and everything worked fine. Now I've made it a web application (I run it on WebsphereAS 5.0) and it has stopped creating the backup files. However the code remained the same.
Any ideas what has happend?
Thanks a lot,
Ondra

I also have the same problem. Did you find a fix?

Can clock synchronization be implemented by pure java?

I want to build a simple distributed application, whose main purpose is to synchronize the local system clock in the slave JVM with the clock in the master JVM. Can it be implemented by pure java? Or I have to use JNI to implement it?
And although the application is mainly used in LAN, the delay of transferring the data of time is small, but is there any algorithm to minimize the difference of system clock between the master and the slave?

No. You can not synchronize the System Clock (clock) in 100% Pure Java.
Using The Network Time Protocol (NTP) and Java, you can access the current time from many servers around the world.
The problem here is that you can't change the clock through Java without an interface to the actaul clock.
Since the clock is a native component (application, service, or utility) you can't change it while being 100% Pure Java.
That does not mean that you can't do it at all. It just will not be Pure Java. You can, however, test to see what system you are on and then adjust the method used.
On a Windows system, the clock is set by the Control Panel applet "Date and Time." This applet can be updated using the Command Driven Interface (CDI), also known as a Command Prompt. To do this you can use the Java object Process. The parameter, a String value, should point to the location of command prompt. Then add a PrintStream object to the Process object. Send the following line (using PrintStream.println()) - "time" and "date"
To update the time use the following line:
time [ time ]
Use the time format: hh:mm:sec
To update the date use the following line:
date [ date ]
Use the date format: mm-dd-yy
This will work on Windows machines (3.x, 95, 98, Me, NT, XP) MS-DOS (all versions with Date/Time capability).

Pure Java API to generate/transform linearized PDFs?

I found some tools on the net to linearize PDF documents. But all use JNI to call some native library (DLL). Is there also a pure Java solution to linearize PDFs?

Martin,
Could you pass on the info on solutions you mentioned on java/jni PDF linearization? Iv'e used the pdfopt script based on ghostscript to linearize iText-created pdf files with jpg images. However, pdfopt applied to pdf files with jpeg-2000 images are not properly linearized for a reason I've not tracked down yet. We're building pdf formats for scanned books as part of the openlibrary.org project at the Internet Archive "open source books" project.
In fact, any free/open source solution for pdf linearization for linux would be very useful, even if not java-based.
Regards,
Todd

Looking for pure Java API to read metadata from an MP4 file.

Hi, I am looking for a pure Java api that can read MP4 metadata. I have been trying to look online for one but have not found anything
suitable. If there are no good api's, can someone point me to resources on how to parse metadata from an MP4, tutorials would be great
as well. I have looked online for that as well but have not found much. Any help would be greatly appreciated.

How to create a setup.exe from a pure java program

i have some program using pure Java Swing.... i already created jar files to make it executable everytime you click on the icon... but i want to create a installer type like setup.exe just like in VB....
How on earth can I do that?!?
Thanks!

This is one...
http://www.excelsior-usa.com/jet.html
And there are a lot more like jexe n stuff.
But look out. Only some convert it to pure native
form. The rest are only launchers - you would still
need a JRE to run yer program.
extremely sorry. Didnt read the post properly .Sorry
