Question

如何管理wso2esb或wso2dss中的事务我们可以选择在wso2esb中创建数据源。虽然我正在使用xadatasource创建外部数据源但是它无法创建我使用以下配置创建的给定问题

Data Source Type*=RDBMS
Name*=USCProduction
Data Source Provider*=External Data Source
Data Source Class Name*=org.postgresql.xa.PGXADataSource
Data Source Properties
====================
url=jdbc:postgresql://localhost:5432/USCProduction
user=admin
password=admin

bbut它无法像这样创建给出错误

ERROR: Error in creating external data source: org.postgresql.xa.PGXADataSource



ERROR - DataSourceRepository Error in creating external data source: org.postgresql.xa.PGXADataSource

我们如何做到这一点并尝试将其复制到数据源文件

<datasource>
            <name>sample</name>
  <xa-datasource jndi-name="java:jboss/PostgresXADS" pool-name="PostgresXADS">
    <driver>postgresql</driver>
    <xa-datasource-property name="ServerName">localhost</xa-datasource-property>
    <xa-datasource-property name="PortNumber">5432</xa-datasource-property>
    <xa-datasource-property name="DatabaseName">USCProduction</xa-datasource-property>
    <security>
      <user-name>admin</user-name>
      <password>admin</password>
    </security>
    <validation>
      <valid-connection-checker class-name="org.jboss.jca.adapters.jdbc.extensions.postgres.PostgreSQLValidConnectionChecker">
      </valid-connection-checker>
      <exception-sorter class-name="org.jboss.jca.adapters.jdbc.extensions.postgres.PostgreSQLExceptionSorter">
      </exception-sorter>
    </validation>
  </xa-datasource>
  <drivers>
    <driver name="postgresql" module="org.postgresql">
      <xa-datasource-class>org.postgresql.xa.PGXADataSource</xa-datasource-class>
    </driver>
  </drivers>
</datasource>
