I made the following changes in struts-config.xml
-----------------------------------------------
<data-sources>
<data-source>
<set-property property="driveClass"
value="COM.ibm.db2.jdbc.app.DB2Driver"/>
<set-property property="url"
value="jdbc b2:xxx"/>
<set-property property="username"
value="db2admin"/>
<set-property property="password"
value="db2admin"/>
</data-source>
</data-sources>
-----------------------------------------------
and Action class I called as
ds = getDataSource(request);
if I run .jsp file I'm getting the following error
java.lang.NullPointerException
at org.apache.struts.taglib.html.JavascriptValidatorTag.doStartTag(JavascriptValidatorTag.java:316)
I need help

Welcome to JavaRanch! Please change your publicly displayed name to comply with the JavaRanch Naming Policy. Thanks!
You need to dig further into your stack trace to find the exact line in your JSP that causes the error. A NullPointerException is usually caused by attempting to invoke a method on a reference that is null so try find where the error occured, then figure out why the object reference is null.

Oddly enough, that error message is caused do to a problem in the DataSource configuration. Although I haven't been able to track down what exactly. I am having the same problem and have searched google and that is how I found this out.
