AbstractMethodError when using Plugins like Tiles and Validator
--- Additional Comments From [EMAIL PROTECTED] 2002-12-28 08:47 ---
Just in case any else encounters this error - I might as well document the
fix ;)
I had to add the following to the MenuPlugIn.java class:
/** The plugin config object provided by the ActionServlet initializing
* this plugin.
*/
protected PlugInConfig currentPlugInConfigObject;
/**
* Method used by the ActionServlet initializing this plugin.
* Set the plugin config object read from module config.
* @param currentPlugInConfigObject
*/
public void setCurrentPlugInConfigObject(PlugInConfig
currentPlugInConfigObject) {
this.currentPlugInConfigObject = currentPlugInConfigObject;
}

This property is set only if the plugin declare the appropriate method. If a plugin doesn't need the property, it should not declare the method. I don't see why your menu-plugin need to declare the method. I suspect that your plugin just need to be recompiled with the latest struts jar files.

Re: Switching Modules - isn't working for me...
Hi, For me it sound like a binary version problem. Maybe one of your plugin has been compiled with an older and incompatible jar file. The tiles-documentation.war file use modules and tiles (module default, example, test). It works on my configuration. Hope this help, Cedric Matt Raible wrote: I tried switching to last night's build, but that appears to be even worse - I can't even use the default module. I get the following error the first time (and all other times) I hit an action: - Root Cause - java.lang.AbstractMethodError at org.apache.struts.action.ActionServlet.initModulePlugIns(ActionServlet.j ava:1096) at org.apache.struts.action.ActionServlet.init(ActionServlet.java:470) at javax.servlet.GenericServlet.init(GenericServlet.java:256) My log file never shows any modules getting initialized (save '').

I compiled with the latest nightly of Struts and got some deprecation warnings
for ApplicationConfig, but it wouldn't compile because of the init
(ActionServlet, ModuleConfig) method:
[javac]
D:\source\StrutsMenu\src\share\com\fgm\web\menu\MenuPlugIn.java:26:
com.fgm.web.menu.MenuPlugIn should be declared abstract; it does not d
efine init
(org.apache.struts.action.ActionServlet,org.apache.struts.config.ModuleConfig)
in com.fgm.web.menu.MenuPlugIn
[javac] public class MenuPlugIn implements PlugIn {
[javac]^
Changing my init method to use init(ActionServlet, ModuleConfig) vs.
(ActionServlet, ApplicationConfig) fixed the problem. Does this break
backwards compatibility with old PlugIns?

The manager can used to deploy any connection pool that implements the codejavax.sql.DataSource/code interface and is configurable totally from JavaBean properties. If your DBMS or container provides a connection pool that meets these requirements, then that component might your first choice. /p p The Jakarta Commons dbcp's BasicDataSource [codeorg.apache.commons.dbcp.BasicDataSource/code] also works well with the DataSource manager, if a native component is not available. The Struts distribution includes a Generic DataSource class in its util package, but this is now only a wrapper around the BasicDataSource. The GenericDataSource class is deprecated as of Struts 1.1 and replaced by direct use of the BasicDataSource. /p p This is how you would specify a default data source for your application from the struts-config.xml: /p precode![CDATA[ data-sources !-- configuration for GenericDataSource wrapper -- data-source set-property property=autoCommit value=false/ set-property property=description value=Example Data Source Configuration/ set-property property=driverClass value=org.postgresql.Driver/ set-property property=maxCount value=4/ set-property property=minCount value=2/ set-property property=password value=mypassword/ set-property property=url value=jdbc:postgresql://localhost/mydatabase/ set-property property=user value=myusername/ /data-source /data-sources ]]/code/pre p This is how you would specify a DBCP BasicDataSource for your application: /p precode![CDATA[ data-sources !-- configuration for commons BasicDataSource -- data-source type=org.apache.commons.dbcp.BasicDataSource set-property property=driverClassName value=org.postgresql.Driver / set-property property=url value=jdbc:postgresql://localhost/mydatabase / set-property property=maxActive value=10 / set-property property=maxWait value=5000 /

Cactus tests failing
Trying to run the Cactus tests, I'm getting a very strange error. Many of the tests succeed just fine, but then I get an HTTP 500 error on the testCookieStringEquals test, with a partial stack trace looking like this: - Root Cause - javax.servlet.ServletException: org.apache.cactus.util.Configuration.isLoggingEnabled()Z at org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:533) at org.apache.jsp.jspRedirector_jsp._jspService(jspRedirector_jsp.java:121) The weird thing about this is that jspRedirector_jsp.java only has 91 lines, but the exception supposedly occurs on line 121! I get the same error with Tomcat 4.1.18 and 4.0.6, and an equivalent error with Tomcat 3.3.1, so either my system is misconfigured, or we have a bug in the tests. Given that the error message refers to a non-existent line of code, I'm having a hard time figuring out which... I'm using Cactus 13-1.3 (the tests fail even earlier with more recent versions) and Ant 1.5.1. Anyone have any idea what's up? -- Martin Cooper -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
