JasperException: Unable to find setter method for attribute: direction when running IBM's java

[base]

I'm attempting to use BASE 2.6.3. I only have Tomcat5 available, and so I cannot use BASE 2.7. I can log in to the BASE interface just fine and everything looks normal, but when I try to access many (but not all) of the menu items, I get the error below. Any idea how to fix the problem?

I think this is a Tomcat-related problem. Which Tomcat5 version are you using? You need at least Tomcat 5.5.16. If you already have this Tomcat version, please give more information about the rest of your system, such as which Java version you are using, operating system etc. Eg. the information in the Help -> About -> Configuration dialog.

Hi there,

Thanks. Here is the information:

Have you tried using Sun's Java runtime?

[base]

Yes, that fixed the problem! Thanks a lot.

I have checked with IBM's java runtime (version 6) and I get the same error with BASE 2.8. I guess this means that there is a difference in their implementation of the reflection API (assuming that this is what Tomcat uses to find the setDirection() method).

The problem may be related to that there are actually two setDirection() methods in the Table taglib (​http://base.thep.lu.se/browser/trunk/src/clients/web/net/sf/basedb/clients/web/taglib/table/Table.java#L372). If i remove the one with a String parameter the error goes away. I am not completely sure that the other method isn't used somewhere else so this is not a solution. There may also be other taglibs that uses a similar setup.

I'll leave this ticket open if someone wants to have a go at fixing it.

If this is an issue try another java RTE (tomcat with Oracle java RTE).
