[Design of JBoss Build System] - Re: Eclipse:eclipse settings for parent pom

by pgier

Yes, I will add that to the parent. I put the parent in svn here because I didn't have a better place: https://svn.labs.jboss.org/labs/jbossbuild/jboss-parent/trunk/ I'll take a look at the plugin and see if I can add the option to separate the test classes output. And maybe we can get that in the next release.

Adrian, this might be interesting for you to have a look at before you start implementing/adding the real thing in the MC. it's in module lightning of jbpm cvs repo. src/org/jbpm/ctx --> context and scopes src/org/jbpm/wire --> wiring regards, tom.

[Javassist development Forum] - Loading all the hierarchical context on a toClass invocation

by mphuget

Hello everybody, I use javassist to create on the fly classes, for instance, I create a class Entity, and then a class Agent extending Entity. No problem to create them but when I try to do a toClass to create a new instance of Agent, an exception occurs because the class Entity is undefined (NoClassDefFoundError exception) whereas the class Entity is in the ClassPool. Do you know how to fix this problem? Thanks in advance mp.

[Design of JBoss Build System] - Eclipse:eclipse settings for parent pom

by wolfc

Can this be added to parent pom? <build> | <plugins> | <plugin> | <groupId>org.apache.maven.plugins</groupId> | <artifactId>maven-eclipse-plugin</artifactId> | <configuration> | <downloadSources>true</downloadSources> | <buildOutputDirectory>target/eclipse-classes</buildOutputDirectory> | </configuration> | </plugin> | </plugins> | </build> Pros: saves me typing -DdownloadSources=true, modifying .classpath by hand Cons: the test output can not be overriden and is thus target/eclipse-classes View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4030150#4030150 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4030150

[Design of JBoss jBPM] - Re: Timer problem in 3.1.4 -- bug or feature?

by tom.baeyens＠jboss.com

yes that is expected and not tunable in 3.1.x with configurations only. in 3.1.x the scheduler service (like all other services used by jbpm) are pluggable. so you could build your own scheduler service that e.g. leverages ejbtimer service. that is exactly what we did added in 3.2.GA, which was just released. in 3.2, the pojo implementation is now multithreaded. and there is also an enterprise service implementation that maps to the enterprise services for async messaging and timers. there is one known limitation with the enterprise services. because of a limitation in the ejb timer spec, we have to loop over all the timers in case we want to delete one by name during process execution. that might not scale very well in some situations. we are going to work out a solution for this in the next version (by replacing the usage of the timer service of one single SLSB with one entity bean per timer) hope this gives you some insight View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4030138#4030138 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4030138
