RE: Webapp classloader question.
But the org.apache classes are not endorsed, only the org.xml.sax and org.w3c.dom. These packages contain mostly interfaces and while the implemenation of the JDK comes with the org.apache classes I do not believe these are considered part of the J2SE platform API. JAXP comes with a specific override mechanism such that if a JAXP implementation is found on the classpath that one can be used ahead of any other implementation. Otherwise developers would be stuck with the JAXP parser in the JRE. This means that a parser in mywebapp/web-inf/lib should be used ahead of any other provided you are using SAXParserFactory/DocumentBuilderFactory to load the parser. At least this is my reading of the JAXP specification and certainly the behaviour I've seen running XML apps from the command line and making sure that I have Xerces/Xalan on the classpath for the application. BTW I'm butting in here assuming I know the whole thread, and this is also a subject dear to my heart as I've had so many go arounds of this on so many different Tomcat versions. BTW2 the Servlet specification was written with exactly this problem in mind, i.e. making sure the 'right' XML parser was loaded Kevin Jones On Fri, 2003-10-10 at 18:16, Cox, Charlie wrote: ok, I just found this link from the archives.

I think the question boiled down to, if we have Xerces on both endorsed and webapps, which one should be used? For tomcat, I would thought that the order for class searching will be webapps, shared, commons (including endorsed), then system. I believed tomcat put endorsed before system is to follows the endorsed classloading spec.. But I also believed forcing delegate model for xerces and xalan maybe overkill?

I found a strange bug in internet explorer cookie handling that could possibile workarounded in tomcat: I have 2 different webapps on 2 different domains (a domain and a subdomain of this domain), e.g.: mydomain.com test.mydomain.com When I enter the first domain, a session cookie for this domain is set. The session then works fine for this domain. Then I view a page from the second domain. IE returns the cookie that was set in the first domain. Tomcat does'nt know that session id in the second context and sets a new cookie. Now the strange thing: The new Cookie is never returned from ie. So the new Session in the second domain is not valid and after each click a new SessionID is generated (i think IE always returns the cookie set in the first domain). A possible solution: If the name of the session cookie would be configurable (per host or per webapp), the hostname could added to that cookie. This would fix this issue on IE.

Manager App
I'm currently using TC 4.1.12. I've been taking advantage of the fact that I can drop an XML file into the tomcat/webapps directory and have this recognized as a context. However I've just started using the manager app. It appears that when I do anything 'serious' with the manager it includes all the contexts defined inside tomcat/webapps and merges their details into tomcat/conf/server.xml. This means that if I change a context in the webapps directory those changes do not get picked up either by tomcat, or by the manager if I do a stop/start, a restart or an undeploy/deploy. I'm assuming this behaviour is a legacy of the fact that adding contexts to the 'webapps' directory is a fairly recent change to TC. I also remember seeing some discussion of the behaviour of the manager app here a little while ago. Are there any plans to change the manager so that changes to contexts declared in the webapps directory get merged back into server.xml?

Is there any particular requirement you want to add to the proposal ? I added some details about the changes. For everyone - the proposal is in CVS, and everyone can contribute to it. One of the main goals is to improve the community, and that means we should be more sensitive to other needs. If you have an itch, please add it to the plan, as a goal for 5.0 ( some may not happen in 5.0.0 ). Not many of the negative comments posted actually contained any suggestions, so I didn't see much worth integrating, except Glenn's comments about lack of detail. The latest Tomcat 5 proposal looks much better. I am still -1 for starting the work until the JCP releases JSR 152 and JSR 154 for public review. There is one addition to the proposal I think we should discuss at this time. That is the organization of the CVS repostories for Tomcat. The trend started a while ago was to break out common components into their own repository. jakarta-tomcat-connectors and jakarta-tomcat-jasper for example. Perhaps this would be the time to consider if there are better ways to organize the code. The reorganization would have three goals: 1. Allow sharing of components between different versions of Tomcat 2. Reduce duplication and maintenance of code in multiple branches of one CVS repository. 3. Make the code base in each repository more tightly focused on what it does, thus making it easier for developers to find bugs and submit patches. As an example, there are now at least 4 different versions of jasper in various repositories. jakarta-tomcat-jasper/jasper34 jakarta-tomcat-jasper/jasper2 jakarta-tomcat/jasper jakarta-tomcat-4.0/jasper Tomcat 5 would add a fifth. There are many other things that would be in common between Tomcat 4 and Tomcat 5 which are not dependent on the Servlet or JSP version.

I did, because the other connection type is not pooled, among many things. I can revert the changes if it is a bad idea. It's only bad because it breaks my code :-) The code I'm using is (I think) very common, I'm simply turning autocommit off.

Unless anybody shouts loudly (and can show me how to do TXs with JDBC under Tomcat) I'd love to see the change reverted. From the commons.

RE: pageEncoding and Jasper
2.10.1 says Defines the character encoding for the JSP page. Values is of the form CHARSET which must be the IANA value for a character encoding. The CHARSET value of contentType is used as default if present, or ISO-8859-1 otherwise. What I was missing was how this is processed by the page compiler - I think I understand now!

Strange looping behaviour in B6
I have a web application under development that's using tag libraries. In my WEB-INF/lib directory I have a bunch of .jar files. I also have a bunch of .jar.old files (I've renamed the old jars rather than replace them). If I leave the .jar.old files in the lib directory TC4B6 goes into a reloading loop for that context. My server.xml looks like this Context path=/course docBase=c:/webapps/coursesapp debug=9 reloadable=true Logger className=org.apache.catalina.logger.SystemOutLogger timestamp=true/ Loader checkInterval=3 / /Context and the context is getting reloaded every 3 seconds without me doing anything. If I take the .jar.old files out the behaviour stops!

RE: New Tomcat 4 installer nightly
- The JAVA_HOME env variable is no longer needed (instead, it looks in the registry to get the JDK path). The problem with this is that when you install the JDK you end up with two JREs. So Java developers may have JAVA_HOME pointed at c:\jdk1.3.1 (say) and the registry is pointing at c:\program files\JavaSoft\JRE\1.3.1 (or similar). This means that adding jars to c:\jdk1.3.1\jre\lib\ext would not work if tomcat is looking for the JRE through the registry. I would prefer to see a check for JAVA_HOME and if that's not set then look in the registry. Or, if both the registry and JAVA_HOME is set, offer the user the choice. If you've already done this then ignore my ramblings!

class reloading
I can't get servlet re-loading to work in TC4b3. Looking at the code -
Loader creates a thread that sleeps until the time set in server.xml
expires. This thread calls StandardClassLoader.modified
The modified call checks the classCache to see if there are any entries
(code is here)
if (classCache.size() 1)
{
return (false);
}
Checking through the code classes are added to the cache in the loadClass
function.
Near the end of that function is this code
try
{
File file = new File(pathname);
if (file.exists() file.canRead())
{
if (debug = 3)
{
log(Caching from ' + file.getAbsolutePath() +
' modified ' +
(new java.sql.Timestamp(file.lastModified())) +
');
}
classCache.put(name, new ClassCacheEntry(clazz, file,
file.lastModified()));
}
} catch(AccessControlException ace)
Printing out the value of 'pathname' just before this code executes gives
jndi:/localhost/AddressBook/WEB-INF/classes\com\develop\ewebjava\lab\Browse
.class,
which means that the 'file' doesn't exist and so doesn't get added to the
cache.
Should that 'jndi:/localhost' be there ?
This is with the latest nightly build BTW,

In addition, the following major bug fixes are included: * Fixes for two reported security vulnerabilities (a "cross site scripting vulnerability" plus a "URL decoding vulnerability") * The JSP servlet (Jasper) that compiles and executes JSP pages now uses its own classloader its associated XML parser, which avoids potential conflicts with parsers included with a web application. * Bug fix updates for directory listings, the WebDAV support, binding to a single IP address (if requested), incorrectly named access log files, URL decoding improvements, form-based authentication, HTTP/1.1 chunking, isUserInRole(), JSP page parsing problems, and many other patches.

Listeners
Tomcat 4.0 stops configuring listeners if one of the listeners in the list isn't present, should it carry on configuring the rest of the listeners it finds? The spec is silent on this and it seems odd that if somebody (maybe accidentally) deletes a listener class all other following listeners are not configured (any listener preceding the missing listener would already have been initialised). I've also raised this as a bug, Thanks, Kevin
RE: Listeners
Here's the rationale for this behavior (and the fact that Tomcat also marks the app unavailable if it didn't initialize all the listeners and filters successfully): But it doesn't, at least not in the latest nightly. I have a listener configured and the class file is missing. Tomcat seems not to have initialised any of the listeners but the application is still available. Let's say you are implementing user authentication yourself, and using filters. You specify connection information to a database in your filter params, but mistype the password so that the connection cannot be established, so your filter's init() method throws an exception. If Tomcat just logged this as a warning and went on deploying your app, it would now be running with *no* authentication, potentially exposing sensitive information. Is that what you *really* want to have happen? One might argue missing listeners would be less severe a risk than missing filters, but IMHO that isn't the container's judgement to make -- the user has an incomplete application deployed; better to make them go fix it rather than trying to run only part of it. But it is a judgement the container is making - In my app it doesn't matter much if the filters/listeners are missing. I would argue that for listeners the behaviour should be the same as for load-on-startup servlets and that the principle of least surprise would be applied. I would guess that initially most listeners would be ported from load-on-startup servlets (mine are), of one of those servlets was missing the application still started, and the servlets still executed. Least surprise tells me that listeners should behave the same way. Is there some way we could configure this in server.xml or do you think that is overkill. BTW should we also add a note in the spec. about this? Kevin Jones DevelopMentor www.develop.com -Original Message- From: Craig R.

RE: Xalan Tomcat: sealing violation
Robert, this is a well known issue that is being worked on. Check back on the list over the last couple of days for another discussion of this :-) Kevin Jones DevelopMentor www.develop.com -Original Message- From: Robert Petersen [mailto:[EMAIL PROTECTED]] Sent: 26 March 2001 11:20 To: [EMAIL PROTECTED] Subject: Xalan Tomcat: sealing violation First - I may have posted this to the wrong list, if so please let me know a more appropriate place to post this. I think there is a bug in the way Tomcat (or the JVM) handles class loading of classes. The problem is this, I have a servlet (filter actually) that attempts to do some XSLT transformations. When the filter tries to get a TransformerFactory a security exception is thrown, java.lang.SecurityException: sealing violation. (The entire stack trace is at the bottom) The root of the problem is when the class loader is trying to load a org.xml.sax.SAXException. The resource is correct in that the code source url returned is "file:C:/Program Files/Apache Group/tomcat/webapps/jdst/WEB-INF/lib/xalan.jar" the is the xalan.jar file bundled with my webapp. The problem arises when the class loader tries to get the package with a call to "getPackage(pkgname);" The class loader doesn't have this package and asks it's parent to see if it can find the package, and sure enough the parent has a package object from org.xml.sax. The problem is this package was loaded earlier and it's url is "file:C:/Program Files/Apache Group/tomcat/lib/crimson.jar", so when the class loader is checking if the package is sealed it compares the two urls, finds they are not the same and throws the exception. A big assumption I have is that what I am doing is legal, I assume that the intention of the class loading systems is so that the base tomcat code can access it's classes with out worry, using whatever version of the classes it likes and that web apps can load their own version of classes without effecting the behavior of tomcat or other web apps. Is this correct? Now you can avoid this problem simply by not asking the package if it is sealed against the code source url. Is this safe? If you do that though another sort of configuration separation problem happens, in the crimson.jar file the property "javax.xml.parsers.DocumentBuilderFactory" is set to "org.apache.crimson.jaxp.DocumentBuilderFactoryImpl", so if I ask for a new TransformerFactory then I get an instance of "org.apache.crimson.jaxp.DocumentBuilderFactoryImpl", if I don't want that type of object I can set the property to my own class, e.g. "org.apache.xalan.processor.TransformerFactoryImpl" but now all the other web apps are forced to deal with my class. Worse yet, some other webapp could come along and switch the property on me. So it appears that there is no sort of "configuration layering" which I think is a problem. Any help would be appreciated.

RE: Still have XML loading problems
The Jasper page compiler needs to have access to all of the bean classes that you might have placed in WEB-INF/classes and WEB-INF/lib. This could be "faked" by setting up yet another class loader that simulates the "real" webapp class loader (in terms of what repositories it gives you visibility to), or by making the special Jasper class loader a sibling of the webapp class loader (rather than a child), and adding the WEB-INF repositories to it as well. This will work as long as you don't create an object in the Jasper class loader and then expect it to be visible in the webapp class loader (or vice versa) -- you get class cast exceptions at that point. Craig, can we do this for now - it will solve these problems in the short term and we can then think about re-writing Jasper? Kevin Jones DevelopMentor www.develop.com
RE: Still have XML loading problems
I'm interested in seeing if we can gather enough folks to start a "Jasper 2.0" effort, on a completely fresh slate. The design of this would take into account the two input syntaxes and everything we've learned, and the implementation could implement many obvious optimizations that would speed up the runtime code as well. What do you think? I think this is a great idea - I'd certainly be interested, Kevin Jones DevelopMentor www.develop.com
Still have XML loading problems
Craig, I'm playing with the 22nd March drop of Catalina, and I've come across a scenario where the new classloading architecture doesn't quite work. I'm using Xerces and Xalan (although Xalan is irrelevant to this). If I access a servlet that uses XML and I don't put Xerces in my web-app/myapp/lib my code fails (exactly what I'd expect). If I put Xerces.jar into web-app/myapp/lib it works, again what I'd expect. However, if I put my XML code into an application listener then Jasper fails to load - I get a Security Exception, sealing violation, while it's load the 'jsp' servlet. It seems that what's happening is that my listener loads, loads Xerces and executes OK. The jsp Servlet then tries to load crimson/JAXP and *bang* sealing violation. Sorry about this - the XML stuff had been going so well until then! Kevin Jones DevelopMentor www.develop.com

RE: Still have XML loading problems
It (the JSP servlet) is loaded early already. It (and its XML parser) are now loaded by another classloader (not sure that was true on the 22nd -- if your Tomcat 4.0 has "jasper-compiler.jar" and "jasper-runtime.jar" separated, then it is for you). I have jasper-compiler.jar in 'jasper' and jasper-runtime.jar in 'lib' The problem is the following scenario: * JSP servlet loads early, parses TLDs from the web.xml file (which causes some JAXP parser classes to be loaded). * You do something with Xerces that causes Xerces classes to be loaded, from your webapps class loader (parent of the one used by the JSP servlet). * You do something with a JSP page that causes more parser classes to be loaded (from the JSP servlet's classloader), including a class with the same fully qualified name as one of the Xerces classes you just loaded. * Under 1.2 this worked. Under 1.3 it gives sealing violation errors I'm not seeing this sequence (I don't think) * I'm loading Xerces in my listener (in fact all I'm doing is using the DocumentBuilder and DocumentBuilderFactory), in the contextInitialized method, this is getting loaded first. * JSP servlet is trying to load - in it's init() method I get the exception No TLDs but I see a call to TldLocationsCache.init This is part of the trace I'm seeing ContextConfig[/KRJ]: Added certificates - request attribute Valve xmlSetupListener: enter contextInitialized xmlSetupListener: leave contextInitialized StandardWrapper[/KRJ:default]: Loading container servlet default default: init StandardWrapper[/KRJ:invoker]: Loading container servlet invoker invoker: init StandardWrapper[/KRJ:jsp]: Using Jasper classloader for servlet jsp jsp: init StandardContext[/KRJ]: Servlet /KRJ threw load() exception javax.servlet.ServletException: Servlet.init() for servlet jsp threw exception at org.apache.catalina.core.StandardWrapper.load(StandardWrapper.java:791) at org.apache.catalina.core.StandardContext.start(StandardContext.java:3135) ... lines omitted for brevity ... - Root Cause - java.lang.SecurityException: sealing violation at java.net.URLClassLoader.defineClass(URLClassLoader.java:234) at java.net.URLClassLoader.access$100(URLClassLoader.java:56) at java.net.URLClassLoader$1.run(URLClassLoader.java:195) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at org.apache.catalina.loader.StandardClassLoader.findClass(StandardClassLoader .java:646) at org.apache.catalina.loader.StandardClassLoader.loadClass(StandardClassLoader .java:1013) at org.apache.catalina.loader.StandardClassLoader.loadClass(StandardClassLoader .java:912) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:313) at org.apache.jasper.compiler.TldLocationsCache.processWebDotXml(TldLocationsCa che.java:161) The only other possible workaround I can think if is to exhaustively load every single class file out of jaxp.jar and crimson.jar at startup time. That seems horrendously wasteful of memory (especially when you consider that this has to be done for each web app). Agreed Kevin Jones DevelopMentor www.develop.com
RE: Still have XML loading problems
Craig, bear with my ignorance of how Catalina works at this point. I'm assuming that the JSP servlet compiles the 'raw' JSP-XML-Java and then compiles this to a .class file. Why does the Jasper class-loader delegate to the web-apps classloader, isn't the Jasper step entirely independent. If so, couldn't the JSP servlet create its own CL that doesn't delegate to the webapps loader, but delegates straight to the shared classloader. In fact we could take tools.jar off-of the classpath and make it available to this classloader only. So the Jasper CL would pick up tools.jar, crimson.jar and jaxp.jar and everything from my webapp lib and classes, but doesn't delegate to the webapp CL. This should have the effect of making Jasper independent of my webapp CL. The other CLs would work the same. It makes the CL architecture slightly more complicated (but it already is complicated). Will this work? Another thought. If Jasper is a two step process (.jsp-XML, XML-Java) as step 1, java-.class as step 2, only the first step needs an XML parser, can we isolate that first step with a separate CL?

Taglibs and Manifests
The current beta-1 of TC4 requires that taglib jar files contain a manifest. TC3.2 doesn't. Is this a requirement anywhere? I've checked the JSP specs and the JAR guide.

[REPOST] Using Xerces in my Application
I posted this about a week ago with no luck. Anybody care to comment? I'm trying to use Xerces in my web application. To do this I put the jar file into WEB-INF/lib. However whenever I try and parse any XML I get a 'sealing' exception. I've just read the recent thread on this and it implies that I can only have one XML parser within Tomcat, or at least that if the class names clash (which they will) things may not work as expected. Can I use Xerces either alongside Crimson? If so, where do I put it. It doesn't work in WEB-INF/lib and only works in tomcat/lib as a replacement for crimson. Reading the sealing discussion I get the impression that using Xerces should be OK as long as the class loader doesn't try and use two classes with the same name from different jars, (or am I way off the mark here?). So shouldn't xerces become the 'default' XML parser for my application? What if I want to use a different parser (such as Oracle's) will it work (I haven't tried this BTW)?

RE: do filters work ...
I have filters working fine on TC 4.0b1
Is demo the name of your web application?
If so your web.xml file should look like this
filter-mapping
filter-nameprePost/filter-name
url-pattern/*/url-pattern
/filter-mapping
filter-mapping
filter-namehelloWorld/filter-name
url-pattern/hello.jsp/url-pattern
/filter-mapping
Even if demo is asubdirectory I would try the first filter mapping here
(i.e. filter everything) and see if that works,

Subject: do filters work ...
I'm sending this to the dev group since I'm dealing w/ tomcat4.0
(catalina)
issues and not sure how far along filters are. I can't seem to get my
filters to work so I have a basic HelloWorld that I'm using. The output of
the jsp is what my problem is.
Everything seems to come up fine (running in stand-alone)
~/logs/catalina.out shows:
catalina.out ---
Starting service Tomcat-Apache
Apache Tomcat/4.0-b1
A shutdown would show:
Stopping service Tomcat-Standalone
Stopping service Tomcat-Apache
Starting service Tomcat-Standalone
Apache Tomcat/4.0-b1
In my ~logs/localhost_access*, the first GET (of my ~/demo/hello.jsp)
returns a 200 (after that it's a 302, anyway to force a non-cached GET?).
The output of the hello.jsp:
_ this is supposed to be an hr
null
Check console output!
_ this is supposed to be an hr
- my hello.jsp -
html
head
titleTesting Filters/title
/head
body
hr
p%=request.getAttribute("hello")%/p
pCheck console output!/p
hr
/body
/html
my filter HelloWorld.java --
package filters;
import javax.servlet.*;
public class HelloWorld extends GenericFilter
{
private FilterConfig FilterConfig;
public void doFilter(final ServletRequest request,
final ServletResponse response,
FilterChain chain) throws java.io.IOException,
javax.servlet.ServletException {
System.out.println("Entering HelloWorld Filter");
request.setAttribute("hello", "Hello World!");
chain.doFilter(request, response);
System.out.println("Entering HelloWorld Filter");
}
}
my generic filter GenericFilter.java -
package filters;
import javax.servlet.*;
public class GenericFilter implements javax.servlet.Filter
{
private FilterConfig filterConfig;
public void doFilter(final ServletRequest request,
final ServletResponse response,
FilterChain chain)
throws java.io.IOException, javax.servlet.ServletException {
chain.doFilter(request, response);
}
public void setFilterConfig(final FilterConfig filterConfig) {
this.filterConfig = filterConfig;
}
public FilterConfig getFilterConfig() {
return filterConfig;
}
}

On a side note: any docs on configuring catalinas, like, how to get it out
of stand-alone mode, and the configuration differences is has of previous

RE: Filter Chains slow first time it is called
I've just taken a closer look at this, it's a browser problem. IE 5.5 has really trouble with content types. Even though I'm setting the type to text/html (in a filter) but at some point I've used IE 5.5 to get the data without the filter. The servlet returns text/xml. It seems that IE5.5 is struggling to reconcile this (that's all I can think of). Netscape has no problems (for once :-) ), Kevin Jones DevelopMentor www.develop.com -Original Message- From: Craig R. McClanahan [mailto:[EMAIL PROTECTED]] Sent: 31 January 2001 19:21 To: [EMAIL PROTECTED] Subject: Re: Filter Chains slow first time it is called Kevin Jones wrote: Subject says it all really. The first time a filter chain is executed for a servlet, it takes about 30 seconds for the response to get back to the client. It would be surprising if this is related to initializing the filter chain -- after all, the chain is constructed for every single request (not just the first one). Are you sure there isn't anything application specific that takes a long time to initialize? This doesn't happen everytime but enough to be repeatable. I'm using Beta 1. I've set the app to be reloadable (with a reload time of 3) and I'm logging to the console if that helps, Logs and a test case (even if it doesn't repeat evey single time) would be quite useful in investigating this.
