It would be great if someone was able to help me with the following.
We currently use Jetty to expose our REST interface (Which is setup with Spring) and I want to be able to set the prefix of the threads that are used to process these calls. I believe I have found the change to cxf that will enable this behaviour:
https://issues.apache.org/jira/browse/CXF-5919
It seems to change the initial "qtp" value to whatever you want. (The version we have does include these changes) The problem is that I cannot actually work out how to set it, initially I tried the following:
<Configure id="server" class="org.eclipse.jetty.server.Server">
<Set name="threadPool">
<New class="org.eclipse.jetty.util.thread.QueuedThreadPool">
<Set name="minThreads">10</Set>
<Set name="maxThreads">1000</Set>
<Set name="threadNamePrefix">myname</Set>
</New>
</Set>
</Configure>
http://wiki.eclipse.org/Jetty/Reference/jetty.xml_syntax#Creating_a_NewObject_and_Setting_It_on_the_Server
But that does not work as it's not the QueuedThreadPool that has the threadNamePrefix value.
I would be great if someone was able to give me some pointers as to how I can update my jetty.xml so that I can set this value.
Thank you

Looking at Jetty source code I see that name attribute is the one you are after. Your example should look like this:
<Configure id="server" class="org.eclipse.jetty.server.Server">
<Set name="threadPool">
<New class="org.eclipse.jetty.util.thread.QueuedThreadPool">
<Set name="minThreads">10</Set>
<Set name="maxThreads">1000</Set>
<Set name="name">myname</Set>
</New>
</Set>
</Configure>
This is the result (from VisualVM) on my setup:

I have a local jetty java project. I would like to run some sql when the server creates any connections. The connections are configured in a jetty-env.xml file. Im hoping there is some oracle jdbc property like "run-sql-on-connect" where I can trigger the sql. Essentially I want to alter the session whenever a connection is established. Is there anything in OracleDataSource.connectionProperties like this?
<New id="OracleDS_local" class="org.mortbay.jetty.plus.naming.Resource">
<Arg>jdbc/local</Arg>
<Arg>
<New class="oracle.jdbc.pool.OracleDataSource">
<Set name="URL">jdbc:oracle:thin:*******</Set>
<Set name="user">*****</Set>
<Set name="password">****</Set>
<Set name="connectionProperties ">
<Set name="run-sql-on-connect" >alter session sql here</Set>
</Set>
</New>
</Arg>
</New>
A possible workaround/solution (depending on the requirements) would be to use a custom context handler and a related event to perform a separate connection and execute the query you want.
I know it's not an optimal solution but it might do the trick.
Reference:
https://www.eclipse.org/jetty/javadoc/jetty-11/org/eclipse/jetty/webapp/WebAppContext.html
<Configure id='oracledbdemo' class="org.eclipse.jetty.webapp.WebAppContext">
<New id="OracleDS_local" class="org.mortbay.jetty.plus.naming.Resource">
...
</Configure>
REPLACE WITH
<Configure id='oracledbdemo' class="<YOUR_CUSTOM_WebAppContext_HERE">

I am trying to add a rewrite rule to my run jetty run Eclipse plugin. I am using Jetty v 8.1.2 and supply a 'jetty-rewrite.xml' in the 'Additional Jetty.xml' Eclipse run configuration option. What I would like to achieve is rewriting the following URL
/hello/world?id=1
to
/
The rewrite works in so far as my local URL is updated correctly. However, regardless of what URL I enter (regardless if it matches the rewrite pattern or not), I get a 404 File not Found error from jetty. Note that '/' is mapped to 'index.html' in my web.xml. I can enter any URL (even the full path to index.html) and I get the same 404 error.
<?xml version="1.0" ?>

I don't use any other jetty configuration files, except the default ones that are loaded by the run jetty run plugin. Thanks for any pointers.
Turns out the problem was that I hadn't realized that <Set name="handler"> essentially 'overwrites' my default handlers. So, to fix it, I changed the last few lines to
<!-- add the rewrite handler to the server -->
<Set name="handler">
<New class="org.eclipse.jetty.server.handler.HandlerCollection">
<Set name="handlers">
<Array type="org.eclipse.jetty.server.Handler">

<Ref id="oldhandler"/>
</Item>
</Array>
</Set>
</New>
</Set>
where oldhandler refers to a previously declared <Get id="oldhandler" name="handler"/>
I use jetty9, and I edit two files:
1) start.ini
add one line: "--module=rewrite"
2) etc/jetty-rewrite.xml
add:
/yyy/(.*)

I am working on a project that uses jetty-env.xml to define some resources in the test environment. It requires that I hijack it and put in my username and password for the resources. Is there a way to define my credentials in an external way and use a property placeholder instead? Like in the Spring applicationConfig.xml I can use ${username} as defined in my system properties.

I new to these tools so I might be closer to an answer than I think. Any help would be appreciated.
Enviroment:
Spring Tool Suite 3.4.0 RELEASE
Maven 3
Jetty Plugin 6.1
Spring 3
If you're using the jetty maven plugin, then you can define your properties in a properties file.
Configure the jetty plugin like this:
<configuration>
<systemPropertiesFile>${project.basedir}/src/test/conf/jetty-env.properties</systemPropertiesFile>
</configuration>
And then your jetty-env.xml can be like this:
<New id="dsDatasource" class="org.eclipse.jetty.plus.jndi.Resource">
<Arg>jdbc/dsProtWb</Arg>
<Arg>
<New class="org.apache.commons.dbcp.BasicDataSource">
<Set name="driverClassName">net.sourceforge.jtds.jdbc.Driver</Set>
<Set name='url'>jdbc:jtds:sqlserver://ROPFDN812Q:4900/dlmp_proteomics_wb_dev;instance=FDNDEV18;domain=mfad</Set>
<Set name="username"><SystemProperty name="LANID" /></Set>
<Set name="password"><SystemProperty name="LANPW" /></Set>
</New>
</Arg>
</New>
You can define environment variables and use the Env tag as a placeholder.
<New id="dsDatasource" class="org.eclipse.jetty.plus.jndi.Resource">
<Arg>jdbc/dsProtWb</Arg>
<Arg>
<New class="org.apache.commons.dbcp.BasicDataSource">
<Set name="driverClassName">net.sourceforge.jtds.jdbc.Driver</Set>
<Set name='url'>jdbc:jtds:sqlserver://ROPFDN812Q:4900/dlmp_proteomics_wb_dev;instance=FDNDEV18;domain=mfad</Set>

We are using Oracle connection Pooling mechanism in our project as our application uses some oracle specific features.
The configuration of our datasource in jetty.xml is as follows:
<Call name="addService">
<Arg>
<New class="org.mortbay.jetty.plus.DefaultDataSourceService">
<Set name="Name">DataSourceService</Set>
<Call name="addDataSource">
<Arg>app_ds</Arg><!--java:comp/env-->
<Arg>
<New class="oracle.jdbc.pool.OracleConnectionPoolDataSource">
<Set name="description">xxxx</Set>
<Set name="user">xxx</Set>
<Set name="password">xxxx</Set>
<Set name="loginTimeout">xxx</Set>
<Set name="URL">jdbc:oracle:thin:#localhost:1521:xxx</Set>
</New>
</Arg>
</Call>
<Call name="start"/>
</New>
Now How do we integrate this datasource with P6Spy, so that P6Spy can print out all the SQL statements on to the console...?
I have previously used P6spy with other datasources like spring's DriverManagerDataSource, other datasources like as
(In Tomcat)
Resource name="jdbc/test" auth="Container"
type="javax.sql.DataSource" driverClassName="oracle.jdbc.driver.OracleDriver"
url="jdbc:oracle:thin:#xxx"
username="xxx" password="xxx" maxActive="65" maxIdle="10"
maxWait="-1" removeAbandoned="true"/>
..etc.
All these datasources take driverClassName as argument where we can provide the "com.p6spyengine.spy.P6SpyDriver" in the place of "oracle.jdbc.driver.OracleDriver" and provide the real driver name in spy.properties. The all worked fine.
But with oracle.jdbc.pool.OracleConnectionPoolDataSource, there is no such property called driverClassName to provide a proxy driver to.
In this case how can i integrate P6Spy with it?
Please help...
Thanks in Advance,
Krishna V
From my experience with Glassfish, I would suggest to:
keep your existing oracle (real) datasource definition
create new one (P6Spy one) used as proxy to real one,
defined like this:
<Call name="addService">
<Arg>
<New class="org.mortbay.jetty.plus.DefaultDataSourceService">
<Set name="Name">DataSourceService</Set>
<Call name="addDataSource">
<Arg>p6spy_ds</Arg><!--java:comp/env -->
<Arg>
<New class="com.p6spy.engine.spy.P6DataSource">
<!-- properties would be irrelevant here -->
<Set name="description">xxxx</Set>
<Set name="user">xxx</Set>
<Set name="password">xxxx</Set>
<Set name="loginTimeout">xxx</Set>
<Set name="URL">jdbc:oracle:thin:#localhost:1521:xxx</Set>
</New>
</Arg>
</Call>
<Call name="start" />
</New>
and make sure to refer the real one from the spy.properties file,
using:
realdatasource=jdbc/app_ds # assuming that app_ds is your real datasource
the last thing is to refer the proxy_ds in all your application logic to make sure to use it (If referring would cost you too much, you can always call the proxy datasource the same as the original one and rename the original one + refer the new name in spy.properties config file)
With Jetty, adding P6Spy is actually a little easier. P6Spy has a P6DataSource that accepts another data source via constructor parameter. This is by far the easiest way to setup P6Spy.
<Call name="addService">
<Arg>
<New class="org.mortbay.jetty.plus.DefaultDataSourceService">
<Set name="Name">DataSourceService</Set>
<Call name="addDataSource">
<Arg>app_ds</Arg><!--java:comp/env-->
<Arg>
<New class="com.p6spy.engine.spy.P6DataSource">
<Arg>
<New class="oracle.jdbc.pool.OracleConnectionPoolDataSource">
<Set name="description">xxxx</Set>
<Set name="user">xxx</Set>
<Set name="password">xxxx</Set>
<Set name="loginTimeout">xxx</Set>
<Set name="URL">jdbc:oracle:thin:#localhost:1521:xxx</Set>
</New>
</Arg>
</New>

<Call name="start"/>

My goal is simple. Configure the maven-jetty-plugin with a JNDI for javamail.
But after hours of googling and reading i cannot figure out exactly what to do....
Can someone please help me with a simple step-by-step instruction.
I just read the documentation at http://docs.codehaus.org/display/JETTY/JNDI, but there is absolutly no information about what file i should be editing...
For example. Where am i supposed to put this???
<Configure id='wac' class="org.mortbay.jetty.webapp.WebAppContext">
...
<New id="mail" class="org.mortbay.jetty.plus.naming.Resource">
<Arg><Ref id="wac"/></Arg>
<Arg>mail/Session</Arg>
<Arg>
<New class="org.mortbay.naming.factories.MailSessionReference">
<Set name="user">fred</Set>
<Set name="password">OBF:1xmk1w261z0f1w1c1xmq</Set>
<Set name="properties">
<New class="java.util.Properties">
<Put name="mail.smtp.host">XXX</Put>
<Put name="mail.from">me#me</Put>
<Put name="mail.debug">true</Put>
</New>
</Set>
</New>
</Arg>
And lastly. Since this is the maven-jetty-plugin, i do not have access to modify any core files, so should there be some kind of xml file i should create and set up to override jetty original configuration?
Add the following configuration to the maven-jetty-plugin:
<jettyEnvXml>src/jetty-env.xml</jettyEnvXml>
Then, you can place that file in that location.
Here are concrete examples:
pom.xml (line 536)
jetty-env.xml
