ASK BODY: When I used CrystalReports in Java in the above environment, I was experiencing some errors.What do you think is the reason why JSP for printing can run without any problems, but only JSP for viewer gets errors?
java
The direct cause is that the servlet container (the servlet running on ) cannot resolve com/sap/security/core/server/csi/XSSEncoder.You must place the jar file containing the class on a browseable class loader.
Check the
·Does the corresponding Jar file exist in /WEB-INF/lib?
·Does the corresponding Jar exist in the environment variable CLASSPATH?
→ In this case, the reference is not reachable depending on the loader delegation relationship.
"Also, the next point of engagement is ""the transfer relationship is wrong and the reference cannot be reached."""
In my experience, I have tried to reference a class on the Earx loader from the War class loader.There are many other cases, so I think we have to design this properly or proceed with try&Error.
That's it
