I'm assuming no one on earth has used crystal reports with java...

try using simpldateformat to format the date appropriately...

maybe the server time is incorrect...

The help on bussines object's website is pretty useless...

Hi,

I'm new to crystal reports. I'm busy evaluating CR 10 and have been going through there examples. I'm having problems trying to view the report in my jsp page. I get the following error:

I'm assuming that it cant find the report. I have all the libraries in place and even copied the reports all over the place. Set the path to the reports in the xml file as stated in the start up guide. I've been struggling with this problem all week. There's so little help on the net regarding this and the help on bussines object's website is useless...
I'm using tomcat 5.

I've been through the Calendar class, Basically it's easy to just add time to a given date. I need to be able to calculate - say - 12 hours from a given date to incorporate the buisiness hours. If the buisiness' hours are from 8am - 5pm, and 12 hours have to be added from, say 2pm, normally the result would be 2am the following morning, but, the buissiness won't be open then. So 12 working hours from 2pm should be 5pm the following day OR 8am the day after that. I also have to incorporate weekends and public holidays, if the buisiness is closed over these periods.

Hope you'll be able to help me with this.

Cheers...

I need to calculate a new date using an hour value eg:
Date : 23 March 2005 14:00 pm
Hours to be added: 12
Working hours : 8am - 5 pm

I need to calculate a new date/time using the working hours, so that the added time falls within those working hours.

Thanx...

Hi...

Can anyone tell me how to create,read and write to microsoft excel sheets...
I need to generate reports and graphs from a database to an excel spread sheet fast and effeciantly through a web application...

Are there any api's available... and is it feasible or a good idea to create reports through ms excel or should i conform to a third-party software?
I found a product called JReport - http://www.jinfonet.com/javareporting.htm
that looks quite interesting...

Please inform me what would be the most appropriate solution.

Thanks

well... i doing a file uploading module... so i need to get the absolute path of the server where the application will be residing. but when i run the following line on my jsp page:

out.println("Dir" + new File("..").getAbsolutePath());
i get - Dir C:\Program Files\Apache Group\Tomcat 4.1\..
instead of d:\Application\

for each client i will ned to make a new directory eg. \Application\documentUploadin\newClientDir
and store that clients documents in that directory...

maybe i need to run that code in a class or ejb since tomacat does not compile java classes... do u think that will work?

Hi...

i posted a question about finding the absolute path on a server...
i found the answer but when i printed it out it displayed the tomcat directory in the absolute path.
is there a way that tomcat can compile my jsp's and servlets in my working directory...

Thanks
