I'm a .Net  developper, but I got a single java file to compile,
having these references in it:
import com.crystaldecisions.client.logic.*;
import com.crystaldecisions.sdk.exception.SDKException;
import com.crystaldecisions.sdk.exception.SDKRuntimeException;
import com.crystaldecisions.sdk.framework.ISessionMgr;
import com.crystaldecisions.sdk.framework.CrystalEnterprise;
import com.crystaldecisions.sdk.framework.IEnterpriseSession;
import com.crystaldecisions.sdk.framework.ITrustedPrincipal;
import com.crystaldecisions.sdk.properties.IProperty;
import com.crystaldecisions.sdk.plugin.CeProgID;
import com.crystaldecisions.webapp.util.html.CookieHelper;
import com.crystaldecisions.webapp.util.html.Encoder;
import com.crystaldecisions.webapp.CEConstants;
import com.crystaldecisions.ePortfolio.framework.common.*;

I learned about java in the past couple days what is enough to compile
the file, and I debugged couple issues, but it seems to me that the
above references are not found and when compiling the file I get  too
many error as this one:

.....
...
LogonAction.java:614: cannot find symbol
symbol  : class HttpServletRequest
location: class
com.crystaldecisions.ePortfolio.framework.logon.LogonAction
HttpServletRequest request, LogonForm logonForm) throws SDKException {
....

...

100 errors
1 Warning

can somebody tell me where  I can  download the Jar files referenced
in the "inport" statement above.

thanks
