in jsf page:

     <p:panel header="airports list">          <p:datatable value="#{airportcontroller.items}" var="item">          <p:column>              <f:facet name="header">id</f:facet>              <h:outputtext value="#{item.airportid}"/>          </p:column> 

jsf code generates error:

 public list<airport> getitems() {      if(items==null){          items = airportfacade.findall();      }      return items;  } 

and persistence code (i using hibernate 4.1 jpa provider):

 public list<t> findall() {      javax.persistence.criteria.criteriaquery cq = getentitymanager().getcriteriabuilder().createquery();      cq.select(cq.from(entityclass));      return getentitymanager().createquery(cq).getresultlist();  } 

the key part of exception appears be:

java.lang.illegalstateexception: web9031: webappclassloader unable load resource [org.postgresql.core.v3.queryexecutorimpl$1], because has not yet been started, or stopped    @ org.glassfish.web.loader.webappclassloader.loadclass(webappclassloader.java:1401)     @ org.glassfish.web.loader.webappclassloader.loadclass(webappclassloader.java:1359)     @ org.postgresql.core.v3.queryexecutorimpl.sendquerypreamble(queryexecutorimpl.java:432)     @ 

pgjdbc tries load class , custom glassfish classloader chokes on it.

i suggest turn minimal self-contained test case can compiled , run standalone, submit posssible glassfish bug. test case vital; if can't reproduce can't act on it.

the other things can think of might have more 1 pgjdbc version in claasspath; might using v4 jdbc driver on ancient java understands jdbcv3 , glassfish masking real error; or might using latest v4 driver (which 1.7-only due build problem) java 1.6.
