Erro de execução do entityManager. como resolver?

Olá Wanderley,

Cole o pedaço do seu código onde está sendo disparada a exception e também o StackTrace completo.
Pela exception apresentada, você deve estar informando algum argumento inválido ao chamar o método de criação de query.

Olá Eder

essa é a parte do codigo do form ?

public FisicoQuimicoView() {
        initComponents();
        if (!Beans.isDesignTime()) {
            entityManager.getTransaction().begin();
        }
    }
    
    /** This method is called from within the constructor to
     * initialize the form.
     * WARNING: Do NOT modify this code. The content of this method is
     * always regenerated by the Form Editor.
     */
    @SuppressWarnings("unchecked")
    // <editor-fold defaultstate="collapsed" desc="Generated Code">
    private void initComponents() {
        bindingGroup = new org.jdesktop.beansbinding.BindingGroup();

        entityManager = java.beans.Beans.isDesignTime() ? null : javax.persistence.Persistence.createEntityManagerFactory("bd_saaePU").createEntityManager();
        query = java.beans.Beans.isDesignTime() ? null : entityManager.createQuery("SELECT f FROM Fisicoquimico f");
        list = java.beans.Beans.isDesignTime() ? java.util.Collections.emptyList() : org.jdesktop.observablecollections.ObservableCollections.observableList(query.getResultList());

e aqui temos uma outra parte da mensagem de erro:

Caused by: Exception [TOPLINK-8034] (Oracle TopLink Essentials - 2.0.1 (Build b09d-fcs (12/06/2007))): oracle.toplink.essentials.exceptions.EJBQLException
[color=red]Exception Description: Error compiling the query [SELECT f FROM Fisicoquimico f]. Unknown abstract schema type [Fisicoquimico].[/color]

vamos lá pessoal encarecidamente peço a ajuda de vcs pois preciso terminar esse projeto não sei mais o que fazer
abaixo segue toda a sequiencia de erro:

conto com vcs para me ajudar a resolver o problema

A classe Fisicoquimico existe? Se existe: não seria FisicoQuimico?

Problema semelhante: http://www.guj.com.br/posts/list/144038.java#776610

Código-fonte onde é disparada a Exception: ParseTreeContext (linhas 161 a 179).

/** 
             * INTERNAL
             * Answer the class associated with the provided schema name
             */
            public Class classForSchemaName(String schemaName,
                    GenerationContext context) {
                ClassDescriptor descriptor = context.getSession()
                        .getDescriptorForAlias(schemaName);
                if (descriptor == null) {

                    // >>> Aqui está sendo disparada a exception <<<
                    throw EJBQLException.unknownAbstractSchemaType(
                            getQueryInfo(), schemaName);

                }
                Class theClass = descriptor.getJavaClass();
                if (theClass == null) {
                    throw EJBQLException.resolutionClassNotFoundException(
                            getQueryInfo(), schemaName);
                }
                return theClass;
            }

O ClassDescriptor é criado nessa classe: Project (linhas 833 a 843).

Como a variável aliasDescriptors deve estar nula, então retorna nulo.

/**
             * PUBLIC:
             * Return the descriptor for the alias.
             */
            public ClassDescriptor getClassDescriptorForAlias(String alias) {
                ClassDescriptor d = null;
                if (aliasDescriptors != null) {
                    d = (ClassDescriptor) aliasDescriptors.get(alias);
                }
                return d;
            }
