Taglib error
Hi, I'm trying to use cache taglib. I did the following steps : 1. Copy the tag library descriptor file to the /WEB-INF subdirectory of my web application. 2. Copy the tag library JAR file to the /WEB-INF/lib subdirectory of my web application. 3. Add a taglib element to your web application deployment descriptor in /WEB-INF/web.xml like this: taglib taglib-urihttp://jakarta.apache.org/taglibs/cache-1.0/taglib-uri taglib-location/WEB-INF/cache.tld/taglib-location /taglib but when tomcat(4.1.29) starts, I've this error: 17-mag-2004 10.36.05 org.apache.commons.digester.Digester error GRAVE: Parse Error at line 7 column 50: Attribute xmlns:xalan must be declared for element type taglib. org.xml.sax.SAXParseException: Attribute xmlns:xalan must be declared for elem ent type taglib. at org.apache.xerces.util.ErrorHandlerWrapper.createSAXParseException(Un known Source) at org.apache.xerces.util.ErrorHandlerWrapper.error(Unknown Source) at org.apache.xerces.impl.XMLErrorReporter.reportError(Unknown Source) at org.apache.xerces.impl.XMLErrorReporter.reportError(Unknown Source) at org.apache.xerces.impl.dtd.XMLDTDValidator.addDTDDefaultAttrsAndValid ate(Unknown Source) In my lib I've xalan-2.5.1.jar xercesImpl.jar xercesSamples.jar xml-apis.jar xmlParserAPIs.jar Any idea? thankx - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
R: Cannot create JDBC driver of class '' for connect URL 'null'
I had your same problem. I couldn't find any solution but I solved the problem in this way: I have set the URL string and the driver name in server.xml as Strings: Environment name=ISAS_CS type=java.lang.String value=jdbc:... / Environment name=ISAS_DN type=java.lang.String value=com.informix.jdbc.IfxDriver / and then I use JNDI lookups for them and I create a connection with: Class.forName(driverName); conn=DriverManager.getConnection(connectionString); -- Ivan -Messaggio originale- Da: Andy Grove [mailto:[EMAIL PROTECTED] Inviato: lunedì 5 aprile 2004 12.03 A: [EMAIL PROTECTED] Oggetto: Cannot create JDBC driver of class '' for connect URL 'null' Hi, I am trying to convert my Tomcat web application to use JNDI to lookup a DataSource rather than using DriverManager directly. My application works fine using DriverManager so I know I have my classpath set up correctly. The problem I have seems to be a very common one yet I cannot find a solution to it using Google. I am getting the following error message when I attempt to look up a DataSource: Cannot create JDBC driver of class '' for connect URL 'null' This implies to me that Tomcat is recognizing my Resource declaration in my conf/server.xml but is not loading the associated ResourceParams.

servlet problem with tomcat 4.0.4
Hello,
I have a servlet that generates a PDF document. The generation task is quite
long, so I have decided to do it in an asyncronous way:
the servlet receives the request of generating the document and outputs a
waiting HTML page that submit a request to the servlet, after a predefined
lap of time (using a javascript setTimeout function), asking if the
document is ready:
HTMLHEAD
TITLEL675FoServlet/TITLE
/HEAD
BODY bgcolor='#99ccff' link=blue vlink=purple
table bgcolor='FF' cellpadding=0 cellspacing=0td width=652
align='center'
script language = JavaScript
window.setTimeout(window.location.href = 'http://...servlet
URL with
parameters';, 15000);
/script
/BODY
/HTML
If the document is ready it is presented to the user else the servlet
generates another HTML page with the same lap of time of the previous HTML
page
Everything works nice with Netscape (4.7).
The problems arise with MS Explorer (tested with versions 5.0, 5.5 or 6.0).
Testing the application we notice that:
1) The servlet generates the first HTML waiting page correctly
2) The first invocation of the subsequent page fails to be activated after
the predefined amount of time but is waiting until the completation of the
generation of document from the servlet
So we decided to comment out the setTimeout function and to put an HTML
button:
HTML
HEAD
script
function reload(){window.location.href ='URL';}
/script
/HEAD
BODY bgcolor=#99ccff
form
input type=button onClick=javascript:reload(); value=Ricarica
/form
/BODY
/HTML
when the user pushes it the page should make another invocation.
This doesn't happend until the completation of the document.
Most strange if the user clicks two times, the second invocation has effect
immediatly, but finally, when the document is generated, fails to retrieve
it because someone else seems to be listing for it (maybe is the first
invocation hanging up?).
We are using Tomcat 4.0.4.
Please help me if someone can imagine a possible solution.
Thanks in advance

bug in Tomcat 4 or .... what?
Hi,
I have a servlet that opens a DataInputStrem on the request (see below)
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException{
try{
// Open the I/O streams
DataInputStream in = new DataInputStream(request.getInputStream() );
After this pice of code I cant' access any more to the request parameters.
Infact this code:
request.getParameter(anyParameter)
retrieves ALWAYS null.
The strange thing is that this servlet was Ok for tomcat 3, but can't work
any more with Tomcat4.
Anyone can explain why opening a DataInputStream alters the
HttpServletRequest?
Thanks

Can't read POST parameters in a Servlet
Hi,
I have this problem: from an HTML page I call a Servlet via a form like this:
form name=richiesta method=post action=servletName
input type=hidden name=in_file value=9177.doc
...
input type=hidden name=port value=8787
/form
In the Servlet I retrieve the parameters with request.getParameter(paramName);
With Tomcat3.x everithing goes well, but with Tomcat 4.0.3 I can't retrieve the
parameters in the Servlet: every getParameter returns null, and printing all with
for (Enumeration namesList = request.getParameterNames(); namesList.hasMoreElements();)
{
String curName =(String)namesList.nextElement();
System.out.println(Param +curName+ value: '+request.getParameter(curName)+');
}
prints nothing!
I really can't figure out where to look for a solution. Any help is welcome!
