Re: Pax-Exam - J8 - How to include javax.activation on the classpath?
Please Ignore. The problem was in the bundle Imports. No need for
systemPackages.

Pax-Exam - J8 - How to include javax.activation on the classpath?
Hi,
This seems like a simple problem, but I am banging my head agains the wall
for two days now and I can't figure it out.
I am trying to write an integration test with commons-email, which depends
on javax.activation...
systemPackages("javax.activation", "com.sun.*"),
...
mavenBundle("javax.activation", "javax.activation-api", "1.2.0"),
mavenBundle("com.sun.mail", "javax.mail", "1.5.6"),
mavenBundle("org.apache.commons", "commons-email", "1.5"),
mavenBundle("com.sun.activation", "jakarta.activation", "1.2.1"),
I keep getting this error though:
[RMI TCP Connection(1)-127.0.0.1] ERROR my.impl - [MyServiceImpl(0)]
Error during instantiation of the implementation object
java.lang.NoClassDefFoundError: javax/activation/DataSource
at java.lang.Class.getDeclaredConstructors0(Native Method)
...
If I add javax.activation to the Import-Packes the runtime fails because
the class cannot be instantiated. I assume because of some interface
conflict but I don't know that for sure.
It must be something obvious, but I don't see it (anymore).
Any help or insight is greatly appreciated.

[pax=jdbc-1.1.0] 65k DB connections with pool of 25.
All - I have been struggling with DB connection errors with PAX-JDBC for a while now, and I couldn't really get my mind around it. Just today I noticed something really bizar. On a Windows Server, PAX-JDBC (sometimes) ends up in a loop creating DB connections until the OS runs out of resources. This is the error message: 2017-06-19 16:34:53,676 [ERROR] qtp1288985130-157 MyRepositoryImpl:686 Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.6.2.v20151217 -774c696): org.eclipse.persistence.exceptions.DatabaseException Internal Exception: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: The driver was unable to create a connection due to an inability to establish the client portion of a socket. This is usually caused by a limit on the number of sockets imposed by the operating system. This limit is usually configurable. For Unix-based platforms, see the manual page for the 'ulimit' command. Kernel or system reconfiguration may also be required. For Windows-based platforms, see Microsoft Knowledge Base Article 196271 ( Q196271). Error Code: 0 When I do a netstat -an | find "" I see thousands and thousands of connections (or at least attempted connections, I don't recall the state of the connection). One other interesting thing to note is that if I increase the maxTotal AND the maxIdle values in the config below, the problem doesn't happen, or at least a lot less frequent. osgi.jdbc.driver.class=com.mysql.jdbc.Driver url=jdbc:mysql://my_db_server:3306/mydb?useSSL=false dataSourceName=jdbc/mynonjta user= password= databaseName= pool=dbcp2 #jdbc.pool.timeBetweenEvictionRunsMillis=1000 #jdbc.pool.softMinEvictableIdleTimeMillis=7000 jdbc.pool.maxTotal=25 jdbc.pool.maxIdle=25 #jdbc.pool.minIdle=10 Could it be that the maxTotal and maxIdle being the same causes some havoc here? The idea is to never close connections once they are open, but I might have misunderstood the settings for these properties. OS Microsof Windows Server 2012 R2. Java 8 PAX-JDBC 1.1.0 Please Advise. It seems fairly reproducible so let me know when there is anything you would like me to test.

[pax-jdbc] How to properly configure connection pool with mySQL
Hi, What is the proper way to configure a connection-pool with pax-jdbc-1.1.0? With the config below I would expect that the #connections grows to a peak, and stays there but I still see the DB connections being closed an re-created like crazy... eventually causing a resource issue on the (Windows) DB server. I am sure I am missing something, but I haven't been able to figure it out yet. I am using mySQL driver 5.1.40 and PAX-JDBC 1.1.0. Any help is greatly appreciated.

Re: [pax-jdbc] mysql driver lockup
Well, After a lot of head scratching, I completely rebooted the DB server machine, and that solved the problem (at least for now). Even though MySQLWorkbench only showed a handful connection it looks like somehow the OS or DB engine ran out of 'something'.

[pax-jdbc] mysql driver lockup
Hi - I am experiencing a driver lockup with pax-jdbc 1.1.0. It always seems to happen when a new connection is being created (which, BTW shouldn’t happen that often because I should be using a connection pool). It does’t happen all the time, but often enough to take the entire application down. Would anyone have a suggestion how/where to start debugging this? All the relevant info should be below.

PAX-EXAM: How to get equinox 3.10 to listen on telnet port in a forked container?
Hi,
I have tried a million (or so it feels...) options, but I can't get the
framework to listen on a console port. Equinox wants something like
'-console 2323' as application parameter but neither the vmOptions,
systemOptions or frameworkOptions give me that format.
I must be missing something.
This is my configuration (well, a snapshot of what I currently have)
return options(
vmOption("-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=8800"),
systemProperty("osgi.console").value("2323"),
systemProperty("osgi.console.enable.builtin").value("true"),
vmOption("-Xmx1024M"),
frameworkProperty("osgi.console.enable.builtin").value("true"),
frameworkProperty("osgi.console").value("2324"),
These are the VM options as reported by JConsole:
-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=8800
-Xmx1024M -Dpax.swissbox.framework.rmi.port=21000 -Dosgi.console=2323
-Dpax.exam.invoker=junit -Dpax.exam.service.timeout=1
-Dosgi.console.enable.builtin=true
-Djava.protocol.handler.pkgs=org.ops4j.pax.url
-Dorg.ops4j.pax.logging.DefaultServiceLog.level=INFO
