Custom tag - setting session through component class

SundarSD

Hello All,

I am trying to create a Custom tag to send the output from control class by running a DQL.

Since DQL requires session by setting to the control using through component class

I have created

CustomTag class ,

custom Control class.

tld file

I have created new method in Custom Control class that accepts sesision and DQL query.

This method will get the results as string.

executDQLQuery(IdfSession , query)

In the Custom tag class, only method that I can see with control arguement is setControlProperties

I tried to get back the string that executed from the above method in Control Class

I am trying to send the string to JspWriter object so that it gets rendered to the page.

But setControlProperties() method is called after renderEnd tag.

Is there any other method that can be used to send the Output from Control class?

or is this approach not correct?

Please share your thoughts

Thanks

Sundar

Any thoughts any one?

I am basically trying to understand how the Control class and ControlTag objects can share properties and methods.

Way I can see is setXXX methods are called whenever atribute in jsp is set and after the render end setControlProperties in control Tag is called.

Control class is accessible from component class so I am kind of stuck.. Any help please

Thanks

I really could not make out what you were trying to do with your control from your post. But I suppose you want to run a DQL query inside the control/tag class, so one approach would as follows:

IDfSessionManager sessMgr = null;
IDfSession session = null;

try {

     String docbase = SessionManagerHttpBinding.getCurrentDocbase();
     sessMgr = SessionManagerHttpBinding.getSessionManager();
     session = sessMgr.getSession(docbase);

} catch (Exception ex) {

DfLogger.error(this, e.getMessage(), null, ex);

} finally {

sessMgr.release(session);

}
