Taglib

Hi all,
I have written a taglib with like this:
class abstract A extends TagSupport
{
protected int numItems;
public void setNumItems(String numItemsStr)
{
this.numItems = Integer.parseInt(numItemsStr);
}
}

class B extends A
{
public void setNumItems(String numItemsStr)
{
super.setNumItems(numItemsStr);
}
}

In taglib.tld, I also declase the attribute numItems.

Deploying onto Weblogic is OK, but when I browse a jsp file, it causes the error like this:
<b>Error in using tag library uri='/WEB-INF/tms.tld' prefix='tms': There is no setter method for property 'numItems', for Tag class '...'<b>
Could you please show me how to solve this???
Thanks,
Regards

Thanks,
But you know, with those classes, I change the variable into rowCount (instead of numItems), nothing's wrong. I really don't know what kind of this error....

Thanks a lot!

It looks like you just needed to recompile :)
Did you try to change back to numItems after it worked for rowCount?

My suggestion is that you should analyse taglib entry in web.xml, tag entries in your.tld, recompile all classes, delete any previously used directories where you held classes for current webapp. All in all, just do a cleanup and it should work. I tried your classes on a clean Tomcat instance and everything is ok. If you have any doubts regarding configuring your webapp -> ask :-)

Btw, when your jsp is already compiled into a servlet, when you modify your java classes (ie. tag classes), you must restart Tomcat because classloader already loaded them. If you are using Orion instead of Tomcat - you don't have to.

Oh, I do not use Tomcat, I use Weblogic 6.1. When I change back to numItems, I still get this error and now when I change again into rowCount, I also get this error.
Finally, i can not come over this error.

I have checked all the entries in web.xml or in .tld files (not only do I check this but also my partner does it with me).

Do you have any idea??

Thanks for your reply!

Neutron

Does weblogic have any work or temp or cache directory where it caches compiled classes? If it has, you can try moving all contents of this directory somwhere else to force use of new compiled classes.
