I can't for the life of me figure out what's going on (and I bet at the end it's a really silly mistake)!

So I have an EAR project (with an EJB and Web project enclosed in it) assigned to my weblogic server. I can start/stop it all fine with no errors...but when I try to get to the index.jsp file using the URL: http://localhost/<project name> (it's in my welcome tag in my web.xml) I get the 404 error. It was working before perfectly, then one day it just did all this and has been doing this since. It's weird because I don't think I've played around with any settings since. Here is the log I get from starting up the server, if there's any more info needed, please let me know, thanks:

Oh ok, I tried starting up tomcat without the app and it worked fine. So it has something to do with the app or Apache Digester possibly?

I forgot to show some of the logging info before the error. I don't know if it makes any difference but here it is:

Aug 10, 2007 11:38:59 AM org.apache.catalina.core.AprLifecycleListener lifecycleEvent INFO: The Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: (OMITTED BECAUSE IT'S REALLY LONG) Aug 10, 2007 11:39:00 AM org.apache.coyote.http11.Http11BaseProtocol init INFO: Initializing Coyote HTTP/1.1 on http-8080 Aug 10, 2007 11:39:00 AM org.apache.catalina.startup.Catalina load INFO: Initialization processed in 1172 ms Aug 10, 2007 11:39:00 AM org.apache.catalina.core.StandardService start INFO: Starting service Catalina Aug 10, 2007 11:39:00 AM org.apache.catalina.core.StandardEngine start INFO: Starting Servlet Engine: Apache Tomcat/5.5.23 Aug 10, 2007 11:39:00 AM org.apache.catalina.core.StandardHost start INFO: XML validation disabled

Then the error shown above shows up

*UPDATE*
I resolved the issue (actually another collegue did). After looking at the vm args, we saw this:

-Djava.endorsed.dirs="C:\Program Files\Apache Software Foundation\Tomcat 5.5\common\endorsed

and put some xml jar file in common\endorsed in my tomcat dir. Thanks for the help though, it pointed me somewhere.

When I try starting up tomcat through eclipse(version 5.5; java 1.5), I get this error and I'm not really sure why, since my collegue have the system running on their machines (I would ask him about this, but he's on vacation):

could anyone please shed some light on this?

Actually, I found a good powerpoint + example code!

Here's the link

http://www.movesinstitute.org/~mcgredo/webServices/XML-RPC.ppt

I know this is a pretty straightforward example, but I just can't seem to get it to work! So I'm trying to follow the steps on implementing apache's XmlRpcServlet (http://ws.apache.org/xmlrpc/server.html)...but it just doesn't seem to work . Here's what I do:

for step 1, i create a package called org.apache.xmlrpc.demo and put the calculator class there. (so it's in tomcat\webapps\<project name>\web-inf\classes\org\apache\xmlrpc\demo)

for step 2, I unjar that xmlrpc-server file, add that properties file, then jar it back up again and put it in the tomcat5\webapps\<project name>\web-inf\lib.

for step 3, I change the web.xml accordingly and place it in the web-inf folder.

I get this error:
Exception in thread "main" org.apache.xmlrpc.XmlRpcException: Failed to create input stream: <a href="http://127.0.0.1:8080/xmlrpc/" target="_blank" rel="nofollow">http://127.0.0.1:8080/xmlrpc/</a> at org.apache.xmlrpc.client.XmlRpcSunHttpTransport.getInputStream(XmlRpcSunHttpTransport.java:60) at org.apache.xmlrpc.client.XmlRpcStreamTransport.sendRequest(XmlRpcStreamTransport.java:141) at org.apache.xmlrpc.client.XmlRpcHttpTransport.sendRequest(XmlRpcHttpTransport.java:94) at org.apache.xmlrpc.client.XmlRpcSunHttpTransport.sendRequest(XmlRpcSunHttpTransport.java:39) at org.apache.xmlrpc.client.XmlRpcClientWorker.execute(XmlRpcClientWorker.java:53) at org.apache.xmlrpc.client.XmlRpcClient.execute(XmlRpcClient.java:166) at org.apache.xmlrpc.client.XmlRpcClient.execute(XmlRpcClient.java:136) at org.apache.xmlrpc.client.XmlRpcClient.execute(XmlRpcClient.java:125) at org.apache.xmlrpc.demo.Client.main(Client.java:27) Caused by: java.io.FileNotFoundException: <a href="http://127.0.0.1:8080/xmlrpc/" target="_blank" rel="nofollow">http://127.0.0.1:8080/xmlrpc/</a> at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1243) at org.apache.xmlrpc.client.XmlRpcSunHttpTransport.getInputStream(XmlRpcSunHttpTransport.java:58) at org.apache.xmlrpc.client.XmlRpcStreamTransport.sendRequest(XmlRpcStreamTransport.java:141) at org.apache.xmlrpc.client.XmlRpcHttpTransport.sendRequest(XmlRpcHttpTransport.java:94) at org.apache.xmlrpc.client.XmlRpcSunHttpTransport.sendRequest(XmlRpcSunHttpTransport.java:39) at org.apache.xmlrpc.client.XmlRpcClientWorker.execute(XmlRpcClientWorker.java:53) at org.apache.xmlrpc.client.XmlRpcClient.execute(XmlRpcClient.java:166) at org.apache.xmlrpc.client.XmlRpcClient.execute(XmlRpcClient.java:136) at org.apache.xmlrpc.client.XmlRpcClient.execute(XmlRpcClient.java:125) at org.apache.xmlrpc.demo.Client.main(Client.java:27)

Maybe my client is incorrect?
package org.apache.xmlrpc.demo; import java.net.MalformedURLException; import java.net.URL; import java.util.ArrayList; import java.util.Map; import java.util.Vector; import org.apache.xmlrpc.XmlRpcException; import org.apache.xmlrpc.client.XmlRpcClient; import org.apache.xmlrpc.client.XmlRpcClientConfigImpl; public class Client { /** * @param args * @throws MalformedURLException * @throws XmlRpcException */ public static void main(String[] args) throws MalformedURLException, XmlRpcException { // TODO Auto-generated method stub XmlRpcClientConfigImpl config = new XmlRpcClientConfigImpl(); config.setServerURL(new URL("http://127.0.0.1:8080/xmlrpc")); XmlRpcClient client = new XmlRpcClient(); client.setConfig(config); Object[] params = new Object[]{new Integer(1), new Integer(1)}; Integer result = (Integer) client.execute("Calculator.add", params); System.out.println(result); } }

Can anybody give a more detailed explanation for dummies (me)?

drawing a picture might help you also to visualize.

^ Yea I think he's being tested on recursion, therefore he needs to show a recursion example to prove he understands the concept, thus efficiency is irrevelant for this situation.

You might want to post this in the IDE section also.

or you could just aoply the toLowerCase method on input and compare the input with 'y' and 'n'.

Yea, Ric's suggestion probably will do the trick.

"java GoodDogTestDrive"

Sorry I have no suggestions, but I know how it feels, the crunch, haha.

Anyway, good luck.

Hi,

I was wondering if anyone familiar with using jbuilder could explain how to setup the Native Executable Builder to work with jdbc, because I've been having problems getting it to work. I can get my project to work when running within Jbuilder but not when running using the executable. Any help would be appreciated.

I was also wondering how to do this.

ugh I feel like an idiot, I figured it out I think thanks!

I'm having problems using Jbuilder to work with my oracle driver. Can anyone help explain how to set Jbuilder up so that it will work?

Thanks.
