CAS问题请教高手..........

问题说明：TOMCAT6 + CASServer3.5，工具 eclipse3.5同一个工作下俩的两个站点：SSOClientTest使用client3，根据说明成功打印出登陆的用户名；SSOClientTest2使用client2.1.11，配置后出现以下错误。
详细信息：

从网上搜索，都说是证书的问题，我的证书确实是已经导入的，而且在版本3中成功了，郁闷啊，在线等~！~！~

NND，新的问题又出现了<c:out value="${sessionScope[CAS:'edu.yale.its.tp.cas.client.filter.user']}"/>这句话是错的，jsp页面中需要导入什么包吗？没看到有关的资料啊type Exception reportmessagedescription The server encountered an internal error () that prevented it from fulfilling this request.exceptionorg.apache.jasper.JasperException: /index.jsp(28,0) "${sessionScope[CAS:'edu.yale.its.tp.cas.client.filter.user']}" contains invalid expression(s): javax.el.ELException: Error Parsing: ${sessionScope[CAS:'edu.yale.its.tp.cas.client.filter.user']}

终于又跑到一个坎上了，郁闷啊。把数据库挂上，又加了好几个缺少的包，然后运行，万幸，终于不出错了，但是登陆又死了：

CASServer3.5。没用过来学习下
我使用过cas-client-3.1.3-release.zip，cas-server-3.3.5-release.zip，能成功实现SSO。
估计你那是CAS server数据库配置有问题，当初我是使用的openLDAP作为数据存储的。
org.jasig.cas.adaptors.jdbc.QueryDatabaseAuthenticationHandler.getPrincipalNameTransformer()Lorg/jasig/cas/authentication/handler/PrincipalNameTransformer大概意思是说 QueryDatabaseAuthenticationHandler 没有 etPrincipalNameTransformer()这个方法？郁闷死了。等下，我把我的配置发一下，除了明确说明的，别的基本都没怎么动，5555555：

依然还是这个问题，唉，郁闷死人鸟严重: Servlet.service() for servlet cas threw exception
java.lang.NoSuchMethodError: org.jasig.cas.adaptors.jdbc.QueryDatabaseAuthenticationHandler.getPrincipalNameTransformer()L
org/jasig/cas/authentication/handler/PrincipalNameTransformer;
找到QueryDatabaseAuthenticationHandler原代码，没发现有啥问题啊，太拿人鸟。QueryDatabaseAuthenticationHandler原码：public final class QueryDatabaseAuthenticationHandler extends
    AbstractJdbcUsernamePasswordAuthenticationHandler {    @NotNull
    private String sql;    protected final boolean authenticateUsernamePasswordInternal(
        final UsernamePasswordCredentials credentials)
        throws AuthenticationException {
        final String username = credentials.getUsername();
        final String password = credentials.getPassword();
        final String encryptedPassword = this.getPasswordEncoder().encode(
            password);

        try {
            final String dbPassword = getJdbcTemplate().queryForObject(
                this.sql, String.class, username);
            return dbPassword.equals(encryptedPassword);
        } catch (final IncorrectResultSizeDataAccessException e) {
            // this means the username was not found.
            return false;
        }
    }    /**
     * @param sql The sql to set.
     */
    public void setSql(final String sql) {
        this.sql = sql;
    }
}
SimpleTestUsernamePasswordAuthenticationHandler的原码：public final class SimpleTestUsernamePasswordAuthenticationHandler extends
    AbstractUsernamePasswordAuthenticationHandler {    public SimpleTestUsernamePasswordAuthenticationHandler() {
        log
            .warn(this.getClass().getName()
                + " is only to be used in a testing environment.  NEVER enable this in a production environment.");
    }    public boolean authenticateUsernamePasswordInternal(
        final UsernamePasswordCredentials credentials) {
        final String username = credentials.getUsername();
        final String password = credentials.getPassword();        if (StringUtils.hasText(username) && StringUtils.hasText(password)
            && username.equals(getPasswordEncoder().encode(password))) {
            log
                .debug("User [" + username
                    + "] was successfully authenticated.");
            return true;
        }        log.debug("User [" + username + "] failed authentication");        return false;
    }
}
除了数据源的配置，还真就没有发现什么不同，那QueryDatabaseAuthenticationHandler怎么会提示没有那什么什么方法呢？
请教一下您是怎么解决的呀，我也遇到了这个问题，怎么弄都是报那个错误java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty
