every week on monday we are generating some reports in the morning. We have no problem with the most of them, but 2 are failing sometimes (irregular).
This is the stacktrace of the exception we get with e-mail:

Have someone an idea why some are failing and the most of them not?
We are using JasperReports Server 4.7 on a Linuxserver (Debian) with a Tomcat.
I see the error 'No such file or directory' which makes me wonder where you are saving the output? Is it being emailed, saved to the repository, or saved somewhere on the file system?

I have created installers using Install4j. I am able to install the tool with these installers on both windows and linux.
but in windows, I am getting below exception

I have googled and found that it may be due to incompatible versions of xercesImpl.jar, downloaded latest jars and tried but no help.
removed xercseImpl.jar and xml-apis.jar, added xerces.jar. But the issue persists.
This problem is fixed in install4j 6.1.6.
The install4j silent update check process seems to hang in case Windows is configured with a "proxy script" that no longer exist. For example: when it is set to http://127.0.0.1:50000/proxy.pac, IE gives a "connection refused error", but install4j will wait indefintely while attempting to download the script.
This also prevents our own application from starting, because it is configured to start after the silent update check.
The installer and updater was created in Install4j 6.1.2. I don't see anything in the change log of 6.1.3 that would fix this issue. Can you have a look or provide us with a work around?

The bug is in JRE classes, so we cannot fix that directly. The only option is to pass the VM parameter
-Dinstall4j.noProxyAutoDetect=true
to the installer so proxy auto-detection is switched off.
I am trying to create a local queue and a mdb that listens this local queue in my WAS 7.0 server. I reffered this URL and followed all the steps given. When i tried to run it am getting the below exception.

When i searched in google it's ask me run a fix pack 29 from IBM, Please guide me is this really require to run this fix pack or we can solve this issue using server config change or please give me a procedure to create a MDB that uses local queue to post and listen a message.Below are my RSA info:
RAS 7.5.5
WAS 7.0
To me it looks like your application server (or application) is misconfigured - jms/messageQueue is not message destination reference. This name is probably encountered when parsing annotations on your classes.
When configuring the server you should configure Connection factory, Queue and Activation spec to match the annotations in your code. Additionally don't forget to set proper resource references in your deployment descriptors.
I try to deploy struts2-showcase.war in Struts2-2.3.1-all.zip into Geronimo 2.2.1.
Geronimo responded the below errors:
011-12-30 15:31:53,294 WARN [TomcatModuleBuilder] Web application . does not contain a WEB-INF/geronimo-web.xml deployment plan. This may or may not be a problem, depending on whether you have things like resource references that need to be resolved. You can also give the deployer a separate deployment plan file on the command line.

Does anybody tell me what's wrong with Geronimo ?
I know Geronimo told me it can not find the class:
org/apache/struts/taglib/html/FormTag object.
But, the object is belongs to Struts1, and my war file use Struts2.
I checked struts2-showcase.war and confirmed that struts2-showcase.war never uses the above object.
Thanks anyway.
never worked with Geronimo but a quick look at the log saying that geronimo-web.xml in not there inside WEB-INF folder.
Check this thread as the person has same issue

Exception: java.lang.RuntimeException: java.lang.NoClassDefFoundError: mp3$1
but it happens only if i run applet with events
and in simple applet i never occurred
This error means the Java runtime cannot find the .class file for an anonymous inner class of your mp3 class. Anonymous inner classes are named OuterClass$1, OuterClass$2, OuterClass$3 and so on. An example of the definition of an anonymous inner class:
button1.addActionListener(
new java.awt.event.ActionListener()
{
public void actionPerformed(java.awt.event.ActionEvent e)
{
// do something
}
}
);
As it seems you are using inner classes, be aware that your mp3.java source file creates various .class files and make sure all of these .class files are available for the runtime environment (via copying, or adding them in a .jar file, etc).
to run the applet on web browser
write java code run the application on java
make the class file by using cmd prompt
give proper path and run your java file on cmd prompt to create class file
make html file add applet code in it <applet code=file.class archive =file.zip/jar></applet>
enabled java console from control panel
run the html file and refresh the window
NOTE: make sure class file, html file,zip or jar file having same name for avoiding any confusion
