Hi,
I have 3 queries…tried reading lots of forum posts but unable to get any idea on solving them
1) I have included the Alfresco environment within my web application and everything starts fine when Alfresco connects to a db already init'd by the Alfresco Web app.
Now, after I cleanup the db and delete the lucene indexes and restart my web app it hangs after the open office connection error.
The Java (jboss) process shoots to 100% and remains there till I kill it.
I'm running my web app on JBoss 4.0.2 and my DB is Mysql 5. OS is Windows XP Prof.
It looks like I need to modify some config files as I feel that Alfresco checks for something in the DB or Lucene index and locks up. Can you please help me out with this issue.
2) I'm planning to use the JCR XPath search rather than Lucene currently. Is there some way that I can disable Lucene completely?
3) Alfresco seems to create some entries in the file system which seem to be some kind of unique IDs. Is there any way to store this in the DB via config file changes?
4) This is a request wrt the Lucene version. Though the Lucene version says 1.4.3 for the Alfresco 1.2 release the actual version seems to be 1.5.x I'm using 1.4.3 for my own app and the jar file contents are different. I've now switched to the Alfresco version.
I'm now planning to switch to the 1.9 release and use the DB Directory code in the compass framework to store the index in the DB.
Will Alfresco move to Lucene 1.9 anytime soon? and if possible provide for an option to store the index in the DB
Eliminating the file system makes it easier to move my application to a clustered environment
thanks!

Listing my web apps configuration below. Before that I want to mention that I have disabled JVM optimizations that are default in JBoss 4.0.2. Not sure if they impact anything though.
1) ear-deployer.xml (server/<server>/deploy folder) :
- Set ?Isolated? to true.
- Set ?CallByValue? to true.
2) jboss-service.xml (server/<server>/conf folder) :
- Set ?CallByValue? to true in ?NamingService? mbean.
My web app configuration:
1) web.xml
I'm not planning to use JSF and therefore eliminated all references to JSF.
2) From the 1.2 source I created each of the jars and then bundled the respective config files into these jars: core.jar, jcr.jar, repository.jar, webclient.jar
3) created the package alfresco.extension in my code's source and placed the following files into it.
a) custom-context.xml
b) custom.properties
though I use the same properties file for every overridden bean, I figured I dont have too many properties to be worrying about hashmaps containing unrequired properties for each bean! This way I have all my custom properties in one file.
c) customModel.xml
This is empty currently but I'll fill it as I proceed.
d) I've written a Util class that provides the ServiceRegistry and JCRRepository.
The Repository startup seems to create the companyHome store. The bootstrap config file mentions creating a new bean overriding ApplicationListener for any custom startup processing.
Since my app does not use Spring I've decided to create any required stores within my existing ServletContext Listener class, since having all the startup code in one format is easier on the mind
hope this post helps others.
If I come across anything interesting I'll continue adding more posts to this thread.

private static WebApplicationContext webAppCtx = null;
public static ServiceRegistry getServiceRegistry()
{
assert (getServletContext()!=null) : "The ServletContext is not available in Utils. Please set this during Application startup.";
return (ServiceRegistry) webAppCtx.getBean(ServiceRegistry.SERVICE_REGISTRY);
}
public static Repository getJCRRepository()
{
assert (getServletContext()!=null) : "The ServletContext is not available in Utils. Please set this during Application startup.";
return (Repository) webAppCtx.getBean(RepositoryFactory.REPOSITORY_BEAN);
}
/**
* @return Returns the context.
*/
public static ServletContext getServletContext() {
return context;
}
/**
* @param context The context to set.
*/
public static void setServletContext(ServletContext context) {
AlfrescoUtils.context = context;
webAppCtx = WebApplicationContextUtils.getRequiredWebApplicationContext(context);
}
public static Object getAlfrescoBean(String beanName) {
assert (getServletContext()!=null) : "The ServletContext is not available in Utils. Please set this during Application startup.";
return webAppCtx.getBean(beanName);
}
}
