我是 ApacheDS 的新手。我刚刚在 ApcheDS 中创建了一个新分区。当我尝试注册我的连接工厂时，出现上述错误..（使用 OracleAQ）

我的代码是;

    // ldap settings
        env.put(Context.INITIAL_CONTEXT_FACTORY, AQjmsConstants.INIT_CTX_FACTORY);
        env.put(Context.PROVIDER_URL, "ldap://localhost:10389/");
            env.put(Context.SECURITY_PRINCIPAL, "uid=admin,ou=system,dc=acme,dc=com"); 
        env.put(Context.SECURITY_CREDENTIALS, "secret");
        env.put(Context.SECURITY_AUTHENTICATION, "simple");

我的 LDIF 文件看起来像；

dn: dc=acme,dc=com
objectClass: organization
objectClass: dcObject
objectClass: top
dc: acme
o: Acme,Inc

dn: cn=OracleContext,dc=acme,dc=com
objectClass: orclContext
objectClass: top
cn: OracleContext

dn: cn=db1,cn=OracleContext,dc=acme,dc=com
objectClass: orclContext
objectClass: top
cn: db1

dn: cn=OracleDBConnections,cn=db1,cn=OracleContext,dc=acme,dc=com
objectClass: orclContext
objectClass: top
cn: OracleDBConnections

dn: cn=OracleDBQueue,cn=db1,cn=OracleContext,dc=acme,dc=com
objectClass: orclContext
objectClass: top
cn: OracleDBQueue

我的连接参数有什么问题？任何帮助将不胜感激？

谢谢，

检查字符串值的正则表达式是Not null and not empty"什么？" 在java中？我试过这样"/^$|\s+/",但似乎不起作用.

我想使用xpath检查xml中的节点是否包含空字符串/空格.我需要使用的xpath表达式是什么？

例如:

 <p:insert_acc_data_file xmlns:p="http://ws.wso2.org/dataservice">
<p:Id>123</p:Id>
<p:Name></p:pName>
</p:insert_acc_data_file>

如何检查Name节点是空的还是包含空格值？

当我用kafka 0.9.0.1运行以下命令时,我得到了这个警告[1].你能告诉我我的主题有什么问题吗？(我正在和在ec2中运行的kafka经纪人交谈)

我使用com.fasterxml.jackson和 io.swagger库。在我的 REST 端点中，我使用org.javamoney.moneta.MoneyGET 查询的类型。在部署战争时，我得到以下异常1；

我遵循了这个参考 并编写了以下代码[2]；并将其注册到@ApplicationPath。但仍然遇到同样的问题。有什么指南真的会有帮助吗？

@ApplicationPath("/rest")
public class RestApplication extends Application {
@Override
    public Set<Class<?>> getClasses() {
        HashSet<Class<?>> set = new HashSet<Class<?>>();
        set.add(com.test.JsonMoneyProvider.class);

[2]

import javax.money.CurrencyUnit;
    import javax.money.Monetary;
    import javax.money.MonetaryAmountFactory;
    import javax.ws.rs.ext.Provider;
    import javax.xml.bind.annotation.XmlTransient;

    import com.fasterxml.jackson.annotation.JsonIgnore;
    import com.fasterxml.jackson.databind.ObjectMapper;
    import com.fasterxml.jackson.jaxrs.json.JacksonJsonProvider;

    @Provider
    public class JsonMoneyProvider extends JacksonJsonProvider {
        public JsonMoneyProvider() {
            ObjectMapper mapper = new ObjectMapper();
            mapper.addMixIn(MonetaryAmountFactory.class, MixIn.class);
            setMapper(mapper);
        }

        public static interface MixIn {
            @JsonIgnore
            @XmlTransient
            MonetaryAmountFactory setCurrency(CurrencyUnit currency);

            @JsonIgnore …

我使用"maven-bundle-plugin"编写了一个OSGi包(其中我尝试将"jruby-complete-1.4.0.jar"作为osgi包,注意只有依赖是"jruby-complete-1.4.0.jar" ")..当我使用diag命令(#diag XX)通过osgi控制台检查捆绑包时,它说有些包丢失了;

osgi> diag 51
reference:file:dropins/jruby-complete-1.4.0.wso2v1.jar [51]

我的pom就像;

<plugin>
                <groupId>org.apache.felix</groupId>
                <artifactId>maven-bundle-plugin</artifactId>

                            org.joni.*,

                        <Import-Package>

因此,我尝试在<Import-Package>选项中添加那些"可选的缺失包",如pom …

我已经安装了findbug,但是当我右键单击并检查时,它在我的项目浏览器中是不可见的.我想再次重新安装插件并检查,但我没有看到卸载插件的选项.

我该如何卸载插件？我正在使用Eclipse版本:Luna Release(4.4.0)

我已经定义了一个模型，参数类型为“ Double”。

@Size(max = 50)
private Double priority;

当我尝试保存时，Hiberante会引发以下异常[1]。

我在这里错过的验证是什么？（我尝试添加@Size，并删除了它，但发生了同样的问题）

我张贴到我的端点，例如;

{
...
"priority":100.0,
..
}

我是PHP / Laravel的新手。

我的模型扩展了默认的Model类。

class LobModel extends Model
class AlarmActions extends LobModel

当我尝试更新AlarmActions表中的一行时；我越来越

SQLSTATE[42S22]: [Microsoft][ODBC Driver 13 for SQL Server][SQL Server]Invalid column name 'updated_at'. (SQL: update [AlarmActions] set [AlarmActionDescription] = sdsf, [UTCDateTimeUpdated] = 2017-08-11 00:42:05.000, [updated_at] = 2017-08-11 00:42:05.000 where [AlarmActionId] = 19621)

updated_at我的AlarmActions表中没有定义列。

但是我看到，在默认的Model类中，定义了以下列。如何跳过这两列？

const UPDATED_AT = 'updated_at';
const CREATED_AT = 'created_at';

我正在调用save更新行的方法。

 $alarmAction->save();
