I have a persistend Book Class with the following properties
PropertyName -> HibernateMappingType -> JavaType
id -> long -> long
title -> text -> String
author -> string -> String
systemId -> long -> long
status -> boolean -> boolean
fullClassification -> string -> string
And my table description looks like this:
So far everything seems good, but when I try to fetch all the values in the table I get the following Exception Message:
20:04:43,832 TRACE BasicExtractor:61 - extracted value ([classifi1_1_0_] : [BIGINT]) - [11]

The code I'm running is:
Session session = SessionFactoryHandler.buildIfNeeded().
openSession();
Criteria crit = session.createCriteria( Book.class );
crit.list();
session.close();
SessionFactoryHandler.closeFactory();
As I understand it is happening on the status property I just don't know why, if I comment the mapping property in the xml it works perfectly but with it it throws always the same exception with the same index 57, it doesn't make a difference the value of that column in the database (which has only one registry).
The mapping file is like follows:
<hibernate-mapping package="com.cetys.librarymanagement">
<class name="com.cetys.librarymanagement.Core.DomainModels.Book" table="book">
<meta attribute="class-description">
This class contains the whole description of a Book,
according to the specification in ALTAIR system.
</meta>
<id name="id" type="long" column="book_id">
</id>
<property name="title" column="book_title" type="text" length="500" not-null="true"/>
<property name="author" column="book_author" type="text" not-null="true"/>
<property name="systemId" column="book_system_id" type="long" not-null="true"/>
<property name="status" column="book_status" type="boolean" not-null="true"/>
<property name="fullClassification" column="book_full_classification"

</class>
</hibernate-mapping>
Any ideas?
From what I see you are trying to map the BIT type in Database to Boolean in your hibernate code.
There is a bug in MySQL with BIT Value, from version 5.0.3 onwards, in that it does not store a single BIT value. It stores something like SET or ENUM. And that often throws up issues, when you are doing a numeric value comparison. For more details check here
http://www.xaprb.com/blog/2006/04/11/bit-values-in-mysql/
You could ask your DBA to change the datatype to tinyint, however if that is not possible, you can change the status mapping from boolean to numeric_boolean, so would be something like
<property name="status" column="book_status" type="numeric_boolean" not-null="true"/>
There are two ways you can achieve the type conversion of attribute
By annotating field with Type
#Type(type = "yes_no")
private boolean isActive;
in DB Y/N will get persisted.
By writing a converter
#Column
#Convert(converter = BooleanConverter.class)
private boolean isActive;
Converter class
public class BooleanConverter implements AttributeConverter<Boolean, Character> {
#Override
public Character convertToDatabaseColumn(Boolean attribute) {
if (attribute)
return 'Y';
else
return 'N';
}
#Override
public Boolean convertToEntityAttribute(Character dbData) {
if ('Y' == dbData)
return true;
else
return false;
}
}
in xml you can replace the type attribute with the converter class name or yes_no
<property name="status" column="book_status" type="yes_no" not-null="true"/>

I am new to Java, I am trying to call a stored procedure from Java.
I am getting this exception for this code

Getting exception like here
--- Cause: java.lang.ClassCastException: java.math.BigDecimal incompatible with java.lang.String; nested exception is com.ibatis.common.jdbc.exception.NestedSQLException:
--- The error occurred in retrieve_value_added_offer.xml.
--- The error occurred while applying a parameter map.
--- Check the SP.objectParameters.
--- Check the output parameters (retrieval of output parameters failed).
--- Cause: java.lang.ClassCastException: java.math.BigDecimal incompatible with java.lang.String
This line in your XML file looks suspicious to me:
<parameter property="errorCode" jdbcType="INTEGER" javaType="java.lang.String" mode="OUT"/>
What type is the errorCode code parameter in your stored procedure?
You have jdbcType="INTEGER", which suggests it's a number, but you also have javaType="java.lang.String", which suggests it's a string. Clearly it can't be both. You haven't included the declaration of your stored procedure so it's impossible to tell which one it actually is.
If your error code is an integer, try changing javaType="java.lang.String" to javaType="java.lang.Integer" (or if that fails, javaType="java.math.BigDecimal" instead). If your error code is a string, change jdbcType="INTEGER" to jdbcType="STRING".
I have liquibase loadData change:
<changeSet author="author" id="13">
<sql>SET IDENTITY_INSERT M_Conversion ON</sql>
<loadData tableName="M_Conversion" separator="~" file="data/13-M_Conversion.csv">
<column name="MconID" type="NUMERIC" />
<column name="MdbtID" type="NUMERIC" />
<column name="MlokID" type="NUMERIC" />
<column name="MconKeyword" type="STRING" />
<column name="MconExtra" type="STRING" />
</loadData>
<sql>SET IDENTITY_INSERT M_Conversion OFF</sql>
<rollback>
<sql>SET IDENTITY_INSERTM_Conversion OFF</sql>
</rollback>
</changeSet>
In the 13-M_Conversion.csv file, there is one value that causes problems for MSSQL: 201~2~200~GETDATE()~ the GETDATE() value for column MconKeyword is not quoted as string in the resulting sql
The sql that the liquibase generates for this data is:
INSERT INTO [pd].[M_Conversion] ([MconID], [MdbtID], [MlokID], [MconKeyword], [MconExtra]) VALUES (201, 2, 200, GETDATE()); but it should be (201, 2, 200, 'GETDATE()')
Problem is, that in method liquibase.sqlgenerator.core.InsertGenerator#generateValues for String values there is call to check if the string looks like function call
public boolean looksLikeFunctionCall(String value, Database database) {
return value.startsWith("\"SYSIBM\"") || value.startsWith("to_date(") || value.equalsIgnoreCase(database.getCurrentDateTimeFunction());
}
and for MSSQLDatabase GETDATE() is exactly currentDateTimeFunction
So the question is, how do I get this specific value to be escaped properly with loadData change?

and all fields are being Indexed excluding the extra fields which i tried adding using the transformer.
And surprisingly only one field "catCount" has been indexed.
You can trust me and i am confident regarding the schema definition and other configurations.
any lead will be higly appriciated ??
Thanks in advance :)
Is it possible to have Oracle type object as an output from a stored procedure, calling same using spring integration?
For example, I have the following in the database:
create or replace TYPE ESP_TRAINING_REQ_OBJ AS OBJECT
(
v_param1 varchar2(25),
v_param2 varchar2(25)
);
create or replace TYPE ESP_TRAINING_RESP_OBJ AS OBJECT
(
v_param1 varchar2(25),
v_param2 varchar2(25)
);
create or replace PROCEDURE TEST_PROC (
v_req_obj IN ESP_TRAINING_REQ_OBJ,
v_resp_obj OUT ESP_TRAINING_RESP_OBJ
) AS
BEGIN
v_resp_obj := ESP_TRAINING_RESP_OBJ(v_req_obj.v_param2, v_req_obj.v_param1);
dbms_output.put_line('TEST_PROC');
END;
However, when I try calling it, I'm getting the following exception:
PLS-00306: wrong number or types of arguments in call to 'TEST_PROC'
Please find spring integration configuration bellow:
<int-jdbc:stored-proc-outbound-gateway
id="ESP_TRAINING" request-channel="inputChannel"
stored-procedure-name="TEST_PROC" data-source="dataSource"
reply-channel="outputChannel"
skip-undeclared-results="false" ignore-column-meta-data="true">
<int-jdbc:sql-parameter-definition name="v_req_obj" direction="IN" type="STRUCT" />
<int-jdbc:sql-parameter-definition name="v_resp_obj" direction="OUT" type="STRUCT" />
<int-jdbc:parameter name="v_req_obj" expression="payload.v_req_obj"/>
</int-jdbc:stored-proc-outbound-gateway>
Please note it works fine if we change SP declaration above, for using STRUCT in request only, for example replacing ESP_TRAINING_RESP_OBJ by a VARCHAR or any other Oracle primitive data type.
For Example:
create or replace PROCEDURE TEST_PROC (
v_req_obj IN ESP_TRAINING_REQ_OBJ,
v_status OUT VARCHAR2
) AS
BEGIN
v_status := v_req_obj.v_param1 || ' and ' || v_req_obj.v_param2;
dbms_output.put_line('TEST_PROC');
END;
I've fixed it doing following:
Updated spring integration version to 3.0.0.RELEASE,
giving support to both type-name and return-type attribues, inside sql-parameter-definition.
Updated stored procedured declaration as follows:
<int-jdbc:stored-proc-outbound-gateway
id="ESP_TRAINING" request-channel="inputChannel"
stored-procedure-name="TEST_PROC" data-source="dataSource"
reply-channel="outputChannel"
skip-undeclared-results="false" ignore-column-meta-data="true">
<int-jdbc:sql-parameter-definition name="v_req_obj" direction="IN" type="STRUCT" />
<int-jdbc:sql-parameter-definition name="v_resp_obj" direction="OUT" type="STRUCT" type-name="ESP_TRAINING_RESP_OBJ" return-type="espTrainingRespObj" />
<int-jdbc:parameter name="v_req_obj" expression="payload.v_req_obj"/>
</int-jdbc:stored-proc-outbound-gateway>
<beans:bean id="espTrainingRespObj" class="com.hsbc.esp.EspTrainingRespObj"/>
Changed EspTrainingRespObj to implement SQLReturnType, as follows:
public class EspTrainingRespObj implements SqlReturnType {
private String param1;
private String param2;
public Object getTypeValue(CallableStatement cs, int paramIndex, int sqlType, String typeName)
throws SQLException {
Object[] attributes = ((STRUCT) cs.getObject(paramIndex)).getAttributes();
this.param1 = (String) attributes[0];
this.param2 = (String) attributes[1];
return this;
}
...
}
The return-type on the <int-jdbc:sql-parameter-definition> for OUT param and SqlReturnStruct must help you to solve the issue.
The test-case in the Framework source codes contains this sample for CLOB handling:
<int-jdbc:stored-proc-outbound-gateway request-channel="getMessageChannel"
data-source="dataSource"
stored-procedure-name="GET_MESSAGE"
ignore-column-meta-data="true"
expect-single-result="true"
reply-channel="output2Channel">
<int-jdbc:sql-parameter-definition name="message_id"/>
<int-jdbc:sql-parameter-definition name="message_json" type="CLOB" direction="OUT" type-name="" return-type="clobSqlReturnType"/>
<int-jdbc:parameter name="message_id" expression="payload"/>
</int-jdbc:stored-proc-outbound-gateway>
<bean id="clobSqlReturnType" class="org.mockito.Mockito" factory-method="spy">
<constructor-arg>
<bean class="org.springframework.integration.jdbc.storedproc.ClobSqlReturnType"/>

I'm stucked with a database problem for several days now. The application hangs after a specific hibernate criteria.list(). Exactly by the following stacktrace:
java.net.SocketInputStream.read(byte[], int, int)
org.postgresql.core.VisibleBufferedInputStream.readMore(int)
org.postgresql.core.VisibleBufferedInputStream.ensureBytes(int)
org.postgresql.core.VisibleBufferedInputStream.read()

org.postgresql.jdbc2.AbstractJdbc2Statement.executeWithFlags(int)
org.postgresql.jdbc2.AbstractJdbc2Statement.executeQuery()
org.hibernate.internal.CriteriaImpl.list()
After some researches and tests I found that the problem is not a blocking query, but a query that is executed forever.
It's a java spring application with the following sessionFactory and transaction manager configuration:
<bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="org.postgresql.Driver" />
<property name="url" value="jdbc:postgresql://localhost:5432/database" />
<property name="username" value="username" />
<property name="password" value="password" />
</bean>
<bean id="sessionFactory"
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="packagesToScan" value="com.myapp.domain" />
<property name="configLocation" value="/WEB-INF/hibernate.cfg.xml" />
</bean>
<tx:annotation-driven transaction-manager="transactionManager" />
<bean id="transactionManager"
class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
The underlying database is PostgreSQL and here is the current hibernate configuration
<hibernate-configuration>
<session-factory>
<property name="dialect">org.hibernate.dialect.PostgreSQLDialect</property>
<property name="hbm2ddl.auto">none</property>
<property name="hibernate.cache.region.factory_class">org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory</property>
<property name="hibernate.cache.use_second_level_cache">true</property>

<property name="show_sql">false</property>
<property name="format_sql">true</property>
<property name="use_sql_comments">false</property>
<property name="order_updates">true</property>
</session-factory>
</hibernate-configuration>
The critical area in the code is:
private void fillEmptyNames() throws CablewatchException {
List<Device> devicesList = deviceDao.getDevices();
if (devicesList != null) {
for (Device device : devicesList {
String name = deviceDao.getDeviceName(device.getModule().getObjectIdentifier(), device.getSubrack(), device.getSlot());
...
}
}
}
The application hangs on the second dao function "getDeviceName". which is implemented as follow:
#Transactional(timeout=30)
public String getDeviceName(long moduleId, int subrackNr, int slotNr) throws CablewatchException {
Criteria criteria = sessionFactory.getCurrentSession().createCriteria(Device.class).add(Restrictions.eq("module.objectIdentifier", moduleId)).add(Restrictions.eq("subrack",subrackNr)).add(Restrictions.eq("slot",slotNr)).addOrder(Order.desc("objectIdentifier")).setMaxResults(1);
List<Device> devicesList = criteria.list();
if (devicesList != null && !devicesList.isEmpty() && devicesList.get(0) instanceof Device) {
Device device = devicesList.get(0);
return device.getName();
}
return null;
}
Also a detail I'm confronted with is that the same passage works fine under Windows, so currently the problem is only happening on Linux.

I executed it from pgAdmin (and replaced the parameters with their values) and it works fine. Below is the query plan:

Following the detail about Linux and Windows version, I've tried the same test but instead of the local database postgresql_9.1.13 (Debian) I used a remote access to postgresql_9.3.5(Windows) and installed and tried postgresql_9.1.13(Windows). Both worked correctly.
I also tried the same code from my Windows system to the remote postgresql_9.1.13(Debian) and another machine with a remote postgresql_9.1.15(Debian). In both cases the problem occurs.
It seems the problem could lay on the Linux version of postgresql_9.1.x.
Thanks in advance.
After debugging the database with the commands Craig and Clemens provided me (display current queries, pg_stat_activity, explain analyze select, pg_locks etc.), I found out that it isn't an infinite loop but due to an access for more than 20.000 entries the running time was very long. And due to the ORM layer this time was even extended to exceed several hours. I'm working on a small redesign of the database to optimize this issue.
Thanks guys for the support.
