I think u might have forgot to set the path for the struts.jar file. check it once.

[Shailesh Pillai]

Hi Uma,
Are you referring to the CLASSPATH variable?
If yes, then its value is as follows :
E:\Oracle\Ora81\jdbc\lib; D:\j2sdk1.4.0_01\bin; D:\jakarta-tomcat-4.1.30\common\lib\servlet-api.jar; D:\jakarta-struts-1.2.0\lib\struts.jar

The struts.jar file is in the lib directory of MyApp folder.
i.e. <TOMCAT-HOME>\webapps\MyApp\WEB-INF\lib\

Hi,
I'm generating a simple user registration application with struts frameworks using Netbeans5.5 preview IDE. i just created a data source in the struts-config.xml file. After including those lines i tried to run my applcation... i got he initial screen of entering the values after pressing the submit button i get the following error.. All my configuration files are generated by the IDE itself
StandardWrapperValve[action]: Servlet action is currently unavailable



My struts-config.xml file looks like

Specify configuration file names. There can be several comma
separated file names (default: ?? )

Specify if the Tiles definition factory is module aware. If true

If false, there will be one common factory for all module. In this
later case, it is still needed to declare one plugin per module.
The factory will be initialized with parameters found in the first
initialized plugin (generally the one associated with the default

true : One factory per module. (default)
false : one single shared factory for all modules

The most significant line in the stack trace is:

javax.servlet.UnavailableException: Parsing error processing resource path /WEB-INF/struts-config.xml

This indicates that Struts can't parse your struts-config.xml file because it has errors. Generally, when you get this message the problem is either that the file contains malformed XML, or XML that does not conform to the DTD. I'd suggest reverting to the original struts-config.xml file that comes with the struts-blank.war file, and add back the elements of the file one by one to see which one is in error.
