[Performance Tuning] - Re: Improve Remote interfaces (marshaling unmarshaling...)

by vons1234

if your client code which looks up EJB resides in same JVM where your EJB's are deployed. then you can use EJB local interface rather than remote interface. Another thing is you can use ServiceLocator pattern and cache the home object to prevent the expensive look up.

[Performance Tuning] - Re: java.net.SocketException: Too many open files on Red Hat

by vons1234

Do you really need maxThreads="1000" in your tomcat connector?? You should not set it that high, that might be reason your CPU is spiking when you do the load test, it will keep creating new threads for your incoming request. Even if you are expecting 500 concurrent request, i think 50 threads should be able to handle that. Also you can use acceptCount which is a queue for all your incoming connection requests when all possible request processing threads are in use. Refer to following URL for the bug which i was talking about https://jira.jboss.org/jira/browse/JBWS-2325 View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4241297#4241297 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4241297

[JBoss jBPM] - jBPM 4 Designer - Code generation

by petitgitan

Hi, I've just started trying out the new designer (Eclipse plugin), and was wondering whether it now supports, or will in the future, the generation of basic data entry screens. This feature was valuable in jBPM 3 for quick prototyping and getting user feedback. Thanks, George View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4241295#4241295 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4241295

[JBoss Portal] - Re: Compile Jboss 32bit on Linux 64bit

by PeterJ

Not sure what you are asking. The JVM is a virtual machine that defines its own instruction set and architecture, including the size of the data types. This virtual machine, within which Java apps run, is the same regardless of the architecture of the host environment, whether 32, 64 or even 48 bits (we have a JVM that runs on a 48bit machine, and JBoss AS runs without changes). Thus, a 64-bit JVM running on a 64-bit Linux OS provides the exact same virtual machine environment for Java applications as would a 32-bit JVM running on Windows (well, because the 64-bit JVM has a larger available memory area, you can assign larger heaps than for a 32-bit JVM). This is what makes the "compile once, run everywhere" mantra for Java true.

[Installation, Configuration & DEPLOYMENT] - Re: Can't get use-try-lock to work

by fishribs

Further update: First, this is for jboss-5.0.1.GA. Second: This seems to be an incompatibility in a configuration attribute type. In initializing the datasource, the class LocalManagedConnectionFactory is being used. This extends BaseWrapperManagedConnectionFactory, which has a method | public void setUseTryLock(int useTryLock) | This would be set by ManagedConnectionFactoryDeployment.setManagedConnectionFactoryAttribute(). I believe the value is coming from DataSourceDeploymentMetaData: | @ManagementProperty(name="use-try-lock", description="The internal lock timeout", | includeInTemplate=true) | public long getUseTryLock() | However, the setter takes an int. The property is defined as a long. The reflection in the method that sets it is looking for something that takes a long, and does not find it. It logs it as a trace, since its not required to be there, so no warning is indicated. In short, there doesn't seem to be a way to configure the use-try-lock timeout.

So, JBOSS mode 32/64 is determined by the version of JVM it supports ? View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4241289#4241289 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4241289

[JBoss AOP] - Re: JDK 5 annotated method pointcut

by flavia.rainone＠jboss.com

Hi! You need to configure the aoppath so that your annotated classes can be found by JBoss AOP. Take a look at the examples build script (at JBoss AOP dist, the script that is used to run the examples). There you will find an example of how aoppath is configured so that JBoss AOP finds your annotations.

by PeterJ

Actually, you do not need to recompile JBoss AS - simple download the binary zip file, unzip it, and run it with either a 32-bit or 64-bit JVM.
