Class could not be accessed
Hi,
We are running Tomcat 4.1.31.
We are busy evaluating Crystal Reports XI R2, and as part of that
evaluation I am trying to run some *.jsp's.
When running the .jsp everything seems fine to be begin with, but when I
try and click any button on the toolbar of the application viewed within
the browser (running within tomcat); the following happens:
1. The image on the button disappears (my source show a path for the
images, so obviously something must be different form when the 'page'
gets loaded via Tomcat and then when the mouse cursor is moved over the
'page').
<img border=0 name="firstImage" id="firstImage" width=22.0px
height=22.0px
src='\CrystalReportViewer\crystalreportviewers115/images/toolbar/firstd.
gif' alt="Go to First Page" title="Go to First Page" ></td>
2. When I try to execute any button (doing a mouse click) I get a 'class
<xxxxx> can not accessed' error even though the particular class is
sitting in the same place/directory as the other classes that made it
possible for the *.jsp to run in the first place.
Now, as far as issue 1) goes. I have a
c:\jakarta-tomcat-4.1.31\webapps\CrystalReportViewer directory within
which my *.jsp's sit I am running. This crystalreportviewers115
directory is also sitting there.
I have also edit c:\jakarta-tomcat-4.1.31\conf\server.xml to have the
following just before the /Host string:
<Context path="/CrystalReportViewer" docBase="CrystalReportViewer"
debug="1" reloadable="true" >
</Context>
</Host>
I have edited c:\jakarta-tomcat-4.1.31\bin\setclasspath to add all *.jar
files for the classes I need to my classpath. (This is apart form
setting my PC's classpath)
I also tried placing them in a
c:\jakarta-tomcat-4.1.31\webapps\CrystalReportViewer\WEB-INF\lib and
then
In c\jakarta-tomcat-4.1.31\common\lib. Then I tried extracting the class
giving me the error to X:\jakarta-tomcat-4.1.31\common\classes...also to
no avail...
I'm obviously missing some small but vital link here. Something about
the setup I must notbe doing right/undertstanding right...
Is there anyone that give me some help? Please?
Regards,
Louise

Thanks for the reply.
I did the context path setting for crystalreportsviewer115
in the tomcat\conf\server.xml as one of Crystal Reports setup docs told me, but I think I must have missed the one about the setting in CRConfig.xml :-)
Yes, it is in WEB-INF/classes, but I don't have anything there for crystalreportsviewer115.
What I do have is the <dataDriverCommon> <Classpath> tag set up to include all the jars including DatabaseConnectors.jar. Is that what you mean? Or is it something that I should have within the
<ExternalFunctionLibraryClassNames>
<classname>
tags?
Thanks!
Louise

Hi Louise,
the key setting is the path to the crystalreportsviewer115
directory: It is set in CRConfig.xml in WEB-INF/classes.
But you have probably done this right in the first place.
Can you copy the exact error message about not finding
any classes? Is it a Tomcat error screen? However, you
need to copy quite a lot of jars from the CR distribution
to your WEB-INF/lib.
Can you possibly move to Tomcat 5.5?
