Crystal reports with java

Hello all,
I am new with Crystal Reports.
I have strange problems.
I created report with parameters and run it from Tomcat.

When i use default parameters window - parameters value which i add don't affect on report result - it uses previous parameters.
If i use custome jsp and add parameters programmatically it's work.

When i try to perform "Search for text" with some text i get:
"ERROR Some parameters are missing values".
If i leave search control empty and perform "Search for text" all work fine - i get parameters window and after this i get report.

Thanks in advance, VitalyWhen assigning value to the parameter make sure you spelled the name correctly and send the proper data that matches to the parameter datatype
