You can pass the configuration ID of a configured data source, rather than the properties of the data source. This example program uses Java Management Extensions (JMX) to connect to a running server and invoke the testConnection method on the DataSourceCfgHelper MBean.
See the Code example disclaimer for legal information about these code examples.
/**
* Description
* Resource adapter test program to make sure that the MBean interfaces work.
* Following interfaces are tested
*
* --- testConnection()
*
*
* We need following to run
*
* From an iSeries command line:
*
* -> QSHELL (Start the QSHELL environment)
*
* -> cd (yourDirectory)
* (change current directory to the directory that holds the java source)
*
* -> javac -extdirs /QIBM/ProdData/WebASE51/ASE/lib -d . testDSGUI.java
* (compile the testDSGUI class)
*
* -> . /QIBM/ProdData/WebASE51/ASE/bin/setupClient
* (produce the $JAVA_FLAGS_EXT environment variable)
*
* -> java $JAVA_FLAGS_EXT testDSGUI
* (call the program)
