RE: ClassNotFoundException WSServlet with Tomcat 7.0.11 on Windows Server 2008 R2 using METRO 2.1
Thanks for the replies so far. Chuck; SEVERE: Allocate exception for servlet TempConvertWS java.lang.ClassNotFoundException: com.sun.xml.ws.transport.http.WSServlet Which usually means you have the requisite class located in more than one place. Given the way you've been scattering jars all over, that's not surprising. Each required .jar file must be in only one place, not multiple. I really only copied what the metro-on-tomcat.xml file does. There's a lot of blog posts about having to have the METRO jars in JAVA_HOME\jre\lib too due to JAVA 1.6 only shipping with JAX-WS 2.0 and METRO needs JAX-WS 2.1. I understand what you're saying and have stripped back the locations of the jar files to just CATALINA_HOME\lib and the problem still persists. I'm beginning to wonder if my Tomcat configuration is correct and there is a problem with the way that I created the JAX-WS artifacts using wsgen due to wsgen not using the correct version of JAX-WS... Chris; Howard: are you sure that you need to put your libraries into Tomcat's lib directories, etc. instead of just putting them all in your webapp's WEB-INF/lib directory? Thats just what the metro-on-tomcat.xml file does so I assumed that was the correct procedure. From the replies I've got that may not be the case. AFAIK, Tomcat does not provide any web services APIs so there shouldn't be any conflicts. Try removing all of the libraries you added to the CATALINA_HOME/lib and CATALINA_HOME/endorsed directories and removing the sever.loader property from catalina.properties (not sure why you'd need that, anyway). I actually got the adding METRO to the server.loader path from this blog post http://blogs.oracle.com/arungupta/entry/metro_on_tomcat_6_x, another blog I read suggested adding the METRO jars to the shared.loader property. And this one http://blog.theunical.com/webservers/tomcat/installation-and-configuration-of-jax-ws-metro-on-tomcat-6/ All of your libraries should be in your webapp's WEB-INF/lib directory only at that point. If you restart Tomcat in that configuration, what is the result? I get the same result, Tomcat starts ok, initializes the METRO libs and WSServlet context listeners, then I get a ClassNotFoundException when browsing to the service's WSDL. There must be something incorrect with the way that I have created the webservice, as from what you've said there doesn't seem to be an extra configuration step that I have missed. Felix; On http://metro.java.net/guide/Using_JAX_WS_2_1_with_JavaSE6.html the metro guys advise to put jaxws-api.jar and jaxb-api.jar - and only those - into the jre endorsed directory. That is necessary, since those api's are part of the jre 6, but in older versions. So the possible duplicate class definitions could come from the fact, that the older api comes with the jre. Regards Felix Those 2 jars, jaxws-api.jar and jaxb-api.jar, are an endless source of confusion. As far as I can make out the web-services.api jar that ships with METRO actually contains the same classes as jaxws-api.jar and jaxb-api.jar. You can download those from JAX-WS section of the METRO site but if you download METRO itself then those jars are included in the web-services.api jar. Although I've been unable to find which jar actually contains the WSServlet class itself. This is only post I've found which actually mentions that jaxws-api.jar and jaxb-api.jar = web-services.api jar http://weblogs.java.net/blog/325/2009/04/03/tip-using-jax-ws-22-metro-20-tomcat-6x-jdk-6 Thanks Howard
Re: How to dynamically create JNDI Context Resources
Resending this as it didn't arrive in my inbox... sorry if you received it already... 2011/5/20 John Fletcher In my application I'm using a library which uses JNDI to locate JMS topics and then operates with them. I successfully configured JNDI references to the JMS topics like this in Context.xml, and everything works nicely: Resource name=jms/flex/TopicConnectionFactory type=org.apache.activemq.ActiveMQConnectionFactory description=JMS Connection Factory factory=org.apache.activemq.jndi.JNDIReferenceFactory brokerURL=tcp://localhost:61616 brokerName=activeMQBroker / Resource name=jms/gds1 type=org.apache.activemq.command.ActiveMQTopic description=Discussion topic for GraniteDS factory=org.apache.activemq.jndi.JNDIReferenceFactory physicalName=test.gds1 / The challenge is that the JMS topics I want to make available to the library depend on some runtime information, i.e. I want my application to create the JMS topics dynamically. Is there a way that I can create these JNDI resources at runtime from my application instead of having to hard-code them into Context.xml? I'm able to upgrade to Tomcat 7 if necessary. I found this, not sure if it could solve my problem? http://tomcat.apache.org/tomcat-7.0-doc/jndi-resources-howto.html#Adding_Custom_Resource_Factories . I'm no expert on JNDI so if there is an altogether better solution to my problem I'm open to it. John
SLL Certificate Chain
Hi, I am running Tomcat 6.0.18 64bit on Windows Server 2008 R2 Enterprise. I obtained a certificate for my server from StartCom, installed it and configured the Connector. The server, intermediate and root certificates are in a keystore file. So far all went fine, except for one problem: Tomcat sends only the server certificate, not the whole certificate chain. This means that Firefox (all newer versions) thinks the certificate is invalid. I tried to import the StartCom certificates into the default keystore cacerts, no difference. The problem is not that Tomcat cant validate the certificate, but that the intermediate certificate is not sent (verified with Wireshark). I tried to set all entries in logging.properties to ALL, but I dont get anything in my logs. Has anyone encountered the same behaviour? server.xml: Connector protocol=org.apache.coyote.http11.Http11Protocol port=443 SSLEnabled=true maxThreads=150 scheme=https secure=true keystoreFile=C:\Program Files\Apache Software Foundation\Tomcat 6.0\tomcat.keystore keystorePass=... keyAlias=intern clientAuth=false sslProtocol=TLS / keytool -list -keystore tomcat.keystore: Keystore-Typ: JKS Keystore-Provider: SUN Ihr Keystore enthält 3 Einträge. startcom.ca.sub, 23.05.2011, trustedCertEntry, Zertifikatsfingerabdruck (MD5): 4F:9B:88:B0:78:F3:16:9F:19:DC:F1:A3:8A:50:DD:82 startcom.ca, 23.05.2011, trustedCertEntry, Zertifikatsfingerabdruck (MD5): 22:4D:8F:8A:FC:F7:35:C2:BB:57:34:90:7B:8B:22:16 intern, 23.05.2011, PrivateKeyEntry, Zertifikatsfingerabdruck (MD5): 30:93:DB:AD:5A:DB:76:00:49:EC:EA:0F:4B:9E:C3:3C keytool -list -v -keystore tomcat.keystore: (output shortened) Keystore-Typ: JKS Keystore-Provider: SUN Ihr Keystore enthält 3 Einträge.

Re: Tomcat 5.5 doesn't support keep-alive?
Thanks for your suggestions, I have previously been through these options,
the code I posted was a shortest path to reproducing my issue. I am ensuring
I read the whole response, and any error response.
Setting the keep-alive header appears to make no difference (compared with
setting nothing) when connecting to either tomcat or httpd. Setting
Connection: Close causes it to run out of addresses very quickly when
connecting to both tomcat and httpd. The fact that connection close causes
it to run out of addresses so much quicker than with keep alive suggests
that there is _some_ keep-alive type behaviour going on, i.e. it is managing
to re-use a certain number of connections, but not enough.
Maybe I'm not really understanding what keep-alive is/does, or I'm
overestimating what tomcat is capable of, but I would expect the java
URLConnection to behave in a pretty similar way whether connected to tomcat
or httpd. As its tomcat whose behaviour is unexpected, I'm hoping someone
here can help me.
Thanks again,
Tim.

Subject: Tomcat 5.5 doesn't support keep-alive?
I have a java client that is making a large number of calls to a servlet
running in a web app in tomcat 5.5.28. I have noticed that if the client
process runs for too long, the client machine runs out of ports throwing a
java.net.BindException: Address already in use: connect. I thought that
java's URLConnection maintained an internal pool of connections, and that
so
long as keep alive was enabled it would re-use the connections.
However, when the server is in tomcat, this does not seem to happen, and it
never sends the keep alive header with the response. I tested it just
making
a get request to a single web page (using the code below), in case my
servlet was doing something wrong, but I have the same issue. Note that
putting the same web page in apache httpd 2.2 does not have the same
problem
- httpd sends the keep alive header in the response and java manages to
pool
the connections properly.
The documentation seems to suggest that tomcat does support keep alive, I
have tried with tomcat 6 which seems to have more keep alive related
settings, but it seems to make no difference.
Note that looking at netstat etc shows that all the old connections are in
time_wait, but because I am making a lot of new connections very often the
old ones haven't timed out and it runs out of local ports.
Can anyone suggest what I might be doing wrong? Any suggestions greatly
appreciated.

The Javadoc for java.net.URL has this to say about the openConnection
method:
A new connection is opened every time by calling the openConnection
method of the protocol handler for this URL.
That seems to be conflicting with this other documentation:
http://download.oracle.com/javase/1.5.0/docs/guide/net/http-keepalive.html
... which says that keep-alive is transparent. I don't see you setting a
Connection: keep-alive header, which you probably should be doing. The
example code in the above document does /not/ explicitly set this
header, but it couldn't hurt.
You should also check this out:
http://forums.java.net/node/656951
Evidently, not properly reading the server's response could be a
problem, too. Note that HttpURLConnection requires that you monitor two
separate streams for responses: the output and error streams. You should
drain one or the other stream based upon the response code you get from
the server.

difference in behaviour of tomcat 6 and tomcat 7 very imp
Hi,
I have done analysis on static references and found a interesting
point al;so i find a difference in behaviour in tomcat 6 andtomcat 7
I created a class (TestStatic) which has a static reference to VO(java bean)
in my servlet i declared TestStatic as member variable and initialized it
there and i deployed my app and hit my servlet and then undeployed it ... i
used eclipse MAT and saw that both TestStatic and VO objects are not getting
garbage collected
then i changed the code in my servlet and removed TestStatic from member
variable i used spring beanfactory to get TestStatic object in my service
method and repeated step of deploying hitting my servlet and undeploying ..
i used eclipse MAT and saw that only VO object are not getting garbage
collected
so what can be concluded static references are never garbage collected ? or
even objects holding static references are not GC'ed.

Pointers for Filter to Deny New Sessions
I'm currently running Tomcat on 2 Linux boxes (versions = 7.0) am looking to write a filter that will 1) intercept all requests to a specific context (say, /Catalog), 2) determine if request has an existing session 3) if there is no session, redirect request to another context I'm a novice with Tomcat filters, so am looking for some useful pointers for this.

Re: GC algorithm
Both tomcat 6 and tomcat are running on the same machine using same JVM and as you said GC algorithms are the province of the JVM which according to my understanding means depends upon JVM then why the difference.

I have done analysis on static references and found a interesting

Um, okay.
I created a class (TestStatic) which has a static reference to VO(java bean)
in my servlet i declared TestStatic as member variable and initialized it
there
Let's see that mess of language above shown in code, shall we?
public class VO {
String name;
public String getName() {
return name;}
public void setName(String name) {
this.name = name;}
}
No code for a servlet called TestStatic was included. Assuming you
aren't being very careful to document a problem that relies on very
detailed information, let's move-on with the code you *did* post.
Your servlet has a reference to TestEnum, not VO, but let's just keep
rollin'.
I've removed some of the code that doesn't affect usage of these
classes, etc.
*public* *class* TestEnum {
*private* BeanName name;
*private* *static* VO vo = *new* VO();
}}
*public* *class* Leak *extends* HttpServlet {
TestEnum a = *new* TestEnum();
}
So, after undeploy, TestEnum.vo remains reachable?
It's possible that you have another leak that is causing the
WebappClassLoader to remain in memory, which will prevent your webapp's
java.lang.Class objects from being collected by the GC. In that case,
the static members will also remain in memory.
As suggested in another thread, you might want to look at a memory
profiler to see what is keeping your webapp's classes in memory.
Yes, things have changed from Tomcat 6 to Tomcat 7, but none of them
affect the JVM's GC algorithm(s). Recent Tomcat 6 and all Tomcat 7
releases include some speculative leak-prevention strategies that can
help reduce ClassLoader-pinning leaks that are out of your webapp's
control, so it's possible that's affecting your observations.
so what can be concluded static references are never garbage collected ? or
even objects holding static references are not GC'ed.
Something tells me it's more complicated than that.
In tomcat static refrence are getting garbage collected but in weblogic it
is not can any body help
If that's the case, I suspect Tomcat's leak-prevention code is helping
you out. You're welcome to read the code: it's quite straightforward.

I haven't done much work with SSL certs in Java, but I wonder what would happen if you imported all of the certs, together, into a single alias in your cert store.

Tomcat latency
Hello: I have a problem where a simple wget call to docs/config/valve.html can sometimes take up to 15 seconds to process. I have a script that does a wget call to valve.html every 5 seconds. Most of the time it's fast. However, today in the past 6 hours I had 13 cases where it took over 3 seconds for wget to return valve.html. This is happening across 7 servers pretty consistently and I can't figure out why. Any suggestions to help me narrow down the problem? I'm going to modify the script to check disk i/o and load when the problem happens. Normally these numbers are sane with upwards of ~60% disk utilization load of ~2.
