Alfresco extension class files - alfresco

As part of customizing Alfresco, I have created a java class by extending 'org.quartz.StatefulJob'Action class in Alfresco. I have registered in Spring Bean definition. But I am getting error as follows. I am deploying this Tomcat server
org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [com.tutorialspoint.HelloWorld] for bean with name 'helloWorld' defined in file [C:\alfresco-content-services\tomcat\shared\classes\alfresco\extension\move-monthily-data-context.xml]; nested exception is java.lang.ClassNotFoundException: com.tutorialspoint.HelloWorld

Can i know the reason of this error ? , What exatctly is the right locaiton to keep extended java file in tomcat? I am using Alfresco 5.2 EE ,

You should be creating a project based on the SDK and packaging your customizations as an AMP which you then install into your Alfresco and/or Share WAR files.
If you need help stepping through how to do that, please work through the tutorials on ECM Architect.
Doing so will package your action class into a JAR and will then place your JAR in the Alfresco WAR under WEB-INF/lib.

what Jar's are needed for and ActiveMQ client, application

I have activemq-client-5.13.3.jar on my class path, but i keep getting
Exception in thread "main" java.lang.NoClassDefFoundError: javax/jms/JMSException
If i use activemq-all-5.13.3.jar on my class path, every thing works.
however I am not allowed to use the activemq-all jar.
added jms-api-1.1-rev-1.jar
and now Exception in thread "main" java.lang.NoClassDefFoundError: javax/management/j2ee/statistics/Stats
You can use maven to determine this with the mvn dependency:tree command or use other maven centric tools to explore the artifacts dependencies.
At a minimum you would need these for v5.13.3
slf4j-api.jar geronimo-jms_1.1_spec.jar hawtbuf.jar
Then you can add an slf4j binding like log4j or logback to get proper logs. There are some others that you might want depending on where / how you are using it like the geronimo-j2ee-management_1.1_spec jar.
Of course if you use maven to build you can make this simpler since it will manage the deps for you.
I found same problem with my java application. I needed to insert Spring Boot for rest web service (Jetty Server) and now ActiveMQ for others data exchange.
With
activemq-client-5.15.11.jar; geronimo-jms_1.1_spec-1.1.1.jar; geronimo-j2ee-management_1.1_spec-1.0.1.jar; hawtbuf-1.11.jar;
all works.

websphere ejb deployment issue : classnotfound error for other ejb references

I have two ejb jars packaged into a ear. say EJb1.jar adn Ejb2.jar. I am deploying it in Webphere 7.0. Ejb1 is referencing to classes in Ejb2.jar. Unless I specify the Ejb2.jar in Manifest.Mf file of Ejb1.jar, the deployment of EAR file fails.
Throws error that build path is incomplete and that referenced class is not found.
Is there any way I can overcome this ? Through some settings in WebSphere console?
I have too many ejb's in this ear referencing each other.
It makes things really difficult to update manifest file each time we make code changes.
Any ideas ?
If you want to avoid that what you need to do is create and EJB Client Jar which holds the interfaces and put it in the EAR/lib directory.
For example if EJB1.jar got MyBean.java and MyBeanLocal.java you will now split it to 2 jars files:
EJB1.jar (EJB Module) holding MyBean.java and EJB1-Client.jar (Utility Jar) holding MyBeanLocal.java
Then you put EJB1-Client.jar in the EAR file lib directory and EJB2.jar will be able to find the interfaces in its classpath.

Jasper Reports NoClassDefFoundError

I'm getting a NoClassDefFoundError error when trying to compile or run a Jasper report.
2012-06-13 14:46:26,710 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/jahtest].[jahtest]] Servlet.service() for servlet jahtest threw exception
java.lang.NoClassDefFoundError: Could not initialize class net.sf.jasperreports.engine.xml.JRXmlDigesterFactory

at net.sf.jasperreports.engine.xml.JRXmlLoader.load(JRXmlLoader.java:172)
at net.sf.jasperreports.engine.xml.JRXmlLoader.load(JRXmlLoader.java:156)
I have a set of java classes wrapped up in a war file and deployed in JBoss default/deploy folder.
I have the jasperreports-4.1.2.jar file in the JBoss default/lib folder so I can't see how there can be a classpath problem because all other jars in the lib folder can be seen.
My front-end app calls a HTTPServlet class which then uses reflection to call the class containing the Jasper code. Everything works fine up until the point where this line is called -
JasperDesign jasperDesign = JRXmlLoader.load(strCompiledReportFile);
The strCompiledReportFile is correct and exists. This all works when I run it through Eclipse, just not when called from my HTTPServlet class.
I'm at the point where I want to ditch Jasper because I've had so many issues with it so this is the last chance saloon.
Cheers for any help you might be able to offer.
I think you are missing few jars that jasper depends on at runtime. Check this thread and make sure you have those jars in your classpath as well.
I'm not sure if it would also apply to your case, but I had a similar problem recently, where after failing to load a font ("problem reading font data"), Jasper Reports would start giving spurious java.lang.NoClassDefFoundError for many of its classes; this problem was caused because java.awt.Font.createFont(int fontFormat, InputStream fontStream) tried and failed to create a temporary file. The error happened inside Tomcat, but not inside Eclipse; what was happening was that Tomcat automatically configures its JVM to point to its temp folder instead of the default one, and Tomcat's temp folder had been deleted.
If you are trying to integrate jasper with springboot application check whether the .jrxml is in the resources folder.

CDI on GlassFish 3.1.1 b12 generates error "WELD-001408 Unsatisfied dependencies"

I'm trying to evaluate CDI on Glassfish 3.1 and even though I have accomplished to make it work well, when I'm trying to split my code in separate deployment modules I get a weird error. More specifically:
I have two classes bundled in the same utility project (let's say the CommonLib.jar); the classnames are UserDatabase and UserDatabaseEntityManager and their definitions are as below (in the PS at the end of this message).
I also have an EAR with an EJB3.1 module in it.
When I choose to deploy the CommonLib.jar as a "Bundled Library" of the EAR, then I get the following error:
Error occurred during deployment: Exception while loading the app : WELD-001408 Unsatisfied dependencies for type [EntityManager] with qualifiers [#UserDatabase] at injection point [[field] #UserDatabase #Inject com.test.TestEJB.itemPersistenceEm]. Please see server.log for more details.
Same error as above I get also when I deploy the CommonLib.jar as a shared library (jar file copied under $glasshfish_installation_path/domains/domain1/lib)
BUT, if I choose to just have the two classes (UserDatabase and UserDatabaseEntityManager) in the EJB project (thus they are compiled within the EJB module), then the injection works fine.
Am I facing a classloader issue? Any ideas how I can get past this issue?
Just a guess, because I faced a very similar problem with Glassfish and CDI a few days ago: Do you have a beans.xml in every JAR, i.e. in the CommonLib.jar and the EJB JAR, so that CDI scans both of them?
My problem resulted from the fact that I thought placing a beans.xml into the EAR would be sufficient, which is not the case.
Sounds like you're running into some of the Glassfish CDI integration issues we've found while working on Seam 3. It could be a couple of them, so you'll have to take a look at see which one it may be. Try testing on JBoss AS7 or Apache TomEE and see if you still have problems.

problem with the injection of an EJB that resides in a jar

I have some problems regarding the EJB injection and I haven't been able to find a solution anywhere.
My situation is the following: I have an EAR file that includes a WAR and several JARs, all listed in the application.xml file. All is working fine for this part.
The problems come out when I try to add what we can call a “plugin system”.
I have a JAR with inside some .xhtml pages, backing beans and EJBs. This JAR, if needed, is inserted inside the EAR in a specific directory (let's call it “plugins”) and is detected from the application at startup.
When the JAR is detected it's path is added to the WAR class loader so all the pages and the backing bean are detected without problems. What is not working is the injection of the EJBs (I tried to use the notation #EJB, #Inject, the lookup...). I can't inject any of the EJBs that is inside the JAR plugin.
My guess is that the application server treats the JAR as a simple library module and doesn't look for any EJB inside it, so they are inside the JAR but not usable from the application.
My question is: there's a way of having this working? I tried to add the JAR in the EAR's MANIFEST.MF but nothing changed...
the application server i'm using is glassfish 3.0. About the application.xml: there's no reference in it about the JARs that are part of what i called "plugin system". This because i detect them when i deploy (or i restart) the application in the application server, so they may or may not be inside the system and i don't really know that before the system is started.
Each plugin JAR is a "collection" of pages and functionalities that can be added or removed from the system dynamically (more less like a real plugin system).
My EAR structure is the following:
MyApp.EAR
META-INF
lib
plugins
plugin1.JAR
app.WAR
logic1.JAR
logic2.JAR
for example: in the application.xml i have the references for app.WAR, logic1.JAR and logic2.JAR (they are always inside the system), at startup the application looks inside the folder "plugins" for any plugin (specific JARs) to be added to the system.
I hope i've been more clear about what i'm trying to do...
It seems that the EJB are not even registered in the JNDI tree of the server. Which application server are you using? You can have a look to this JNDI tree to see if the EJBs are there, but the way to do this depends on the specific server.
How are you declaring the JAR that contains the EJBs in the EAR application.xml?
It should be someting lide this:
<application>
....
<module>
<ejb>nameOfTheJarFile.jar</ejb>
</module>
</application>
The Jar should be in a the "/lib" directory of the EAR.
I hope this helps.
