i want to dynamic load datasource configuration profile from server when report is runing but throw a exception,so where has mistake occured?! dbconfig.txt as a profile

the code is :

importPackage( Packages.java.io,Packages.java.util,Packages.java.net );
importPackage( Packages.javax.servlet.http );

req = reportContext.getHttpServletRequest( );
propPath = this.getClass().getClassLoader().getResourceAsStream("dbconfig.properties");

if ( propPath != null )
{
props = new java.util.Properties( );
props.load( propPath );

odaURL = new String(props.getProperty("url"));
odaDriverClass = new String(props.getProperty("driver"));
odaUser = new String(props.getProperty("userid"));
odaPassword = new String(props.getProperty("password"));
}

The Exception is:

Hi kevin23_hy,

Is this code in the beforeOpen of the dataSet or the initialize of the report? The error suggests that it's in the initialize method. Do you have different code in the initialize method too?

kevin23_hy

o,the script it in the datasource beforeopen or in the initalize as well,there is a problem?
with my knows that there are 3 ways to dynamic load datasources
,1.load profile 2.spring configuration 3.jndi
,obviously jndi is easier to use but no idea figure out,so can you give a sample to illustated that.?Surprised for reply on holiday and best wishes for you,happy xmas day!

So, you use this same script in both methods? Since the error is with the initialize method, I'm just making sure this is the code you're using in there.

Let me know.
