When deploying a “HelloWorld” Web project to Tomcat 4, I get this error:
SEVERE: Parse Error at line 6 column 52: Document root element “web-app”, must match

DOCTYPE root “null”.

What operating system and version are you running?
Win XP Pro
What Eclipse version and build id are you using? (Help > About Eclipse

Platform)
Eclipse version: Version: 3.0.1
Build id: 200409161125
– Was Eclipse freshly installed for MyEclipse?
Ywa
– If not, was it upgraded to its current version using the update manager?
– Are any other external plugins installed?
viPlugin
– How many plugins in the <eclipse>/plugins directory are like

org.eclipse.pde.*
Directory of C:\eclipse\plugins

01/03/2005 10:55 AM <DIR> org.eclipse.pde.build_3.0.1
01/03/2005 10:54 AM <DIR> org.eclipse.pde.core_3.0.1
01/03/2005 10:55 AM <DIR> org.eclipse.pde.doc.user_3.0.0
01/03/2005 10:55 AM <DIR> org.eclipse.pde.junit.runtime_3.0.0

01/03/2005 10:55 AM <DIR> org.eclipse.pde.ui_3.0.1
What MyEclipse version are you using? (Help > About Eclipse Platform >

Features)
3.8.3
What JDK version are you using to run Eclipse? (java -version)
j2sdk1.4.2_06
What JDK version are you using to launch your application server?
j2sdk1.4.2_06
What application server are you using?
I installed Tomcat 4.1 using the std Windoze .exe installer from Apache
I tested the install it works fine.
I configured the Tomcat 4 connector in MyEclipse
I set it to use the j2sk1.4.2_06 JDK
I configured the TOMCAT_HOME in the Java>Build Path>Classpath

Variables
Name: TOMCAT_HOME
Value: C:\Program Files\Apache Group\Tomcat 4.1
I had to reconfigure the JRE to point to the top-level JDK dir, not

the JRE dir, so that when starting Tomcat, it could find tools.jar
What steps did you take that resulted in the issue?
I started Tomcat 4 server from MyEclipse using the j2sdk1.4.2_06 JDK
I tested http://localhost.8080/ from the Web Browser. It works fine.
I created a HelloSid Web Project, using all defaults.
I created a HelloSid.jsp using all the defaults.
I added <% out.println(“Hello Sid”); %> to the JSP page
I used the MyEclipse deployment wizard, selected the HelloSid project
and added the Tomcat 4 server.
I immediately got this error in the Tomcat console:

Are there any exceptions in the Eclipse log file? (<workspace>/.metadata/.log)

Here is the content of /HelloSid/WebRoot/web.xml:
<?xml version=”1.0″ encoding=”UTF-8″?>
<web-app version=”2.4″
xmlns=”http://java.sun.com/xml/ns/j2ee&#8221;
xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance&#8221;
xsi:schemaLocation=”http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd”&gt;

</web-app>

This is the default web.xml generated by the MyEclipse Web Project wizard.

Are there any exceptions in the Eclipse log file?

(<workspace>/.metadata/.log)
I stopped Eclipse.
I renamed the .log file to saved.log
I changed HelloSid.jsp slightly and saved it.
.log is created and here is its contents:

SEVERE: Parse Error at line 6 column 52: Document root element “web-app”, must match

DOCTYPE root “null”.

Sounds like your web.xml file is borked, most likely you forgot the DOCTYPE definition. Please paste the file for us to look at, or for a quick workaround, create a new web project (J2EE 1.3 or 1.4 compliant, whichever you need) then copy the DOCTYPE def out of that default web.xml file into yours and save it, stop tomcat, redeploy and start tomcat.

Actually, I included the web.xml file in the mess above, but it was easy to miss. Here is again:
<?xml version=”1.0″ encoding=”UTF-8″?>
<web-app version=”2.4″
xmlns=”http://java.sun.com/xml/ns/j2ee&#8221;
xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance&#8221;
xsi:schemaLocation=”http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd”&gt;

</web-app>

This was autogenerated by MyEclipse, when I created a vanilla J2EE 1.4 project

Your XML is fine, it works on my local install, however the exception here is more telling:

SEVERE: Parse Error at line 6 column 52: Document is invalid: no grammar found.
org.xml.sax.SAXParseException: Document is invalid: no grammar found.

Can you double check your XML Catalog: Window > Prefs > MyEclipse > Editors > XML > XML Catalog and see if the web app 2.4 schemas is listed? If not, are you able to access the following file from within a browser? http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd, if not, do you have your MyEclipse INternet proxy settings correct (assuming you are behind a proxy?) Windows > Prefs > MyEclipse > Internet Tools > Internet Proxy

[ssidner]

Thanks for the quick response, Riyad.

1) XML Catalog: I looked in the list and found 2.3 (-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN) but not 2.4

2) URI: Yes, I can retrieve this. I used the MyEclipse Web Browser from inside Eclipse.

3) A workaround: I went into the example Web apps in the Tomcat 4.1 installation and found a web.xml. I copied this over the web.xml in my HelloSid project, cut out all the content in <web-app/> and deployed it. Now Tomcat is happy. Here is the web.xml that works:
<?xml version=”1.0″ encoding=”UTF-8″?>
<!DOCTYPE web-app
PUBLIC “-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN”
“http://java.sun.com/dtd/web-app_2_3.dtd”&gt;
<web-app>
</web-app>

4) Tomcat: Could it be that Tomcat 4.1 doesn’t use the web.xml actual schema, and instead uses an older DTD? Note that the web.xml above uses a 2.3 !DOCTYPE.

Thank you again for your help.

[Riyad Kalla]

Sid, sorry for missing that; Tomcat 4.1 does not support the web 2.4 spec and most likely doesn’t support Schema based validation for the web.xml file which is why it was giving the same error it would as if you had no doctype definition in the file. If you want to use web2.4 spec you need to upgrade to Tomcat 5.x.

Best of luck and good job troubleshooting that.
