About loading of hibernate configuration in HibernateHelper.

[quepasa]

First, i want to sorry for my very intermediate english :)

So... in jBPM config-file (jbpm.cfg.xml) exists a string


when i try to execute this code

JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();
 try {
 jbpmContext.deployProcessDefinition(processDefinition);
 } finally {
 jbpmContext.close();
 }

there exception throws with message Exception in thread "main" org.hibernate.HibernateException: /hibernate.cfg.xml not found.

now see the full stack trace:

Exception in thread "main" org.hibernate.HibernateException: /hibernate.cfg.xml not found
 at org.hibernate.util.ConfigHelper.getResourceAsStream(ConfigHelper.java:147)
 at org.hibernate.cfg.Configuration.getConfigurationInputStream(Configuration.java:1405)
 at org.hibernate.cfg.Configuration.configure(Configuration.java:1427)
 at org.jbpm.db.hibernate.HibernateHelper.createConfiguration(HibernateHelper.java:91)

 at org.jbpm.JbpmContext.deployProcessDefinition(JbpmContext.java:173)
 at ru.emd.escom3.core.CoreTest.main(CoreTest.java:52)

and the cause of this exception is that the HibernateHelper.java trying to use specified hibernate's config-file like a resource in the class path. Look here:

public abstract class HibernateHelper {
...
 public static Configuration createConfiguration(String cfgXmlResource, String propertiesResource) {
....
 // if a special hibernate configuration xml file is specified,
 if (cfgXmlResource!=null) {
 // use the configured file name
 log.debug("creating hibernate configuration resource '"+cfgXmlResource+"'");
 configuration.configure(cfgXmlResource);
 } else {
 log.debug("using default hibernate configuration resource (hibernate.cfg.xml)");
 configuration.configure();
 }
....
 }
}

here we can see, that

configuration.configure(cfgXmlResource);

is called when config-file is a xml-file (it's my case).

And the configuration is the instance of Configuration class (it is in hibernate source code), and method configure() of this class trying to load transmitted file-name like a resource.

BUT MY hibernate.cfg.xml IS NOT A RESOURCE.

It is an ordinary file on file system, and i have a question: how to use such hibernate's config-file in this case ?

*So... in jBPM config-file (jbpm.cfg.xml) exists a string:

[quepasa]

Damn, xml formatted data is not supported in this forum :(

so, those xml is:

string name="resource.hibernate.cfg.xml"

value="/hibernate.cfg.xml"

[mputz]

by default, the hibernate.cfg.xml and jbpm.cfg.xml files are residing in the same directory, often bundled within a jar:

[mputz@mputz lib]$ jar -tvf jbpm-configs.jar
 0 Thu Aug 30 01:05:28 CEST 2007 META-INF/
 71 Thu Aug 30 01:05:28 CEST 2007 META-INF/MANIFEST.MF
 18765 Thu Sep 27 15:34:52 CEST 2007 hibernate.cfg.xml
 2978 Wed Oct 17 11:35:56 CEST 2007 jbpm.cfg.xml
 735 Mon Jun 11 14:22:10 CEST 2007 jbpm.mail.templates.xml

and the configuration property in jbpm.cfg.xml contains no leading slash:

<string name="resource.hibernate.cfg.xml" value="hibernate.cfg.xml" />

[quepasa]

And what ?

Ok, there my mistake with leading slash in configuration property "resource.hibernate.cfg.xml". But i've tested it without this slash too - and the algorithm of hibernate's config file loading was same as described before, in my previous post.

What if i do not want to store hibernate's config file in the jar-file ?
What if i use a jbpm-jpdl.jar lika a ordinary library in my jboss deployable web-module ? Tell me, please, where i need to store hibernate.cfg.xml in that case ?

If you don't want the *cfg.xml files in a separate jar, you could include it in the classpath, for a web-app this would be WEB-INF/classes. Here is a (partial) listing of a modified jbpm-console.war, where the configs are taken from the WEB-INF/classes folder.

./jboss-console.war
images
index.jsp
META-INF
sa
ua
WEB-INF

./WEB-INF/classes:
hibernate.cfg.xml
jbpm.cfg.xml
jbpm.mail.templates.xml
messages.properties

./WEB-INF/lib:
el-api.jar
el-ri.jar
gravel.jar
jbpm4jsf.jar
jbpm-identity.jar
jbpm-jpdl.jar
jsf-api.jar
jsf-facelets.jar
jsf-impl.jar

Is that coming close to what you are trying to do?
