I'm using Mule Standalone. From Mule Studio I'm using a connector I've installed, but since the standalone doesn't have it, it throws an error saying that it can't find the connector amqp:connector etc...
How can I install components in the Mule Standalone?
It should be brought in your application /lib directory by Maven, as a dependency, when you build its package.
For the latest version of the AMQP transport, use:
<dependency>
<groupId>org.mule.transports</groupId>
<artifactId>mule-transport-amqp</artifactId>
<version>3.4.0</version>
</dependency>
Check to see that your connector is in your projects class path before you export to standalone. You can do this automatically if you drag and drop your connector in a flow and save it.

I need some information of log4j2 for updating our central versions of Mule CE 3.9.0 and Mule CE 3.9.5 (CE=Community Edition).
What is the best way to protect them and does downloading only jar files from Apache site https://dlcdn.apache.org/logging/log4j/2.12.3/ be useful to patch Mule CE 3.9?
Regards
As a summary you only need to find the vulnerable jars in the mule-server and in the mule flows deployed in the apps folder.
A Java project is a set of java class and libraries with complex dependencies relationship, but easy to replace one of them (manually or automated with maven), so no matter how or where log4j is being used, we just need replace the jar file.
mule community server 3.9.0
In this version, with this command find . -type f -iname "*log4j*" we will get the log4j jars:
As we can see, the version prior to the 2.14.x
log4j-jul-2.8.2.jar
log4j-jcl-2.8.2.jar
log4j-slf4j-impl-2.8.2.jar
log4j-core-2.8.2.jar
log4j-api-2.8.2.jar
log4j-1.2-api-2.8.2.jar
But according to the official maven repository, this version is affected too :(
Just the 2.17.0 is safe to use
Source: https://mvnrepository.com/artifact/org.apache.logging.log4j/log4j-core
If this change breaks your mule, just delete the specific vulnerable class:
zip -q -d
log4j-core-*.jar org/apache/logging/log4j/core/lookup/JndiLookup.class

mule flow or mule app
This is not the server, is the app developed by programmers, packaged as .zip and deployed to the mule apps folder in the server.
In this layer, the app can ignore completely the server configurations and has its own jar versions.
If you don't use maven (rare), you need to search and replace the jar, app by app, similar to the server with find command but in the specific app folder:
/opt/mule_server/apps/my-mule-app
If you use maven, you could find if the jar is used with the pom.xml previewer of Eclipse Ide or with command mvn dependency:tree. Check this:
https://stackoverflow.com/a/68916675/3957754
Remember: If you not use directly this jar, you need to check if mule esb server uses it.
Here some tips from manual to automated pipelines:
mule esb monolithic with manual deployment
In this case you need to fix the server and your apps.
for the server, backup, stop, search the jar on lib folder and replace it with the 2.17 (after vulnerability fix) and start. Test if everything is working
for the mule apps, the process is the same: stop the mule server, go to your mule apps and one by one, search the jar and replace it. Start the mule server and test if everything is working
git repository , maven and one mule app by server
In this case, you don't have a big server with a big mule containing a lot of mule apps/flows. You have one light server for just one mule app.
Just search the dependency in your pom with maven and replace it.
Push your changes and in the next deploy( manual or automated) your mule app will be fixed.
Also note that this approach fix the app, not the server.
git, docker
If you are using docker, the things are easy. Just search the Dockerfile (usually in a git repository). In this file there are a lot of sentences, since the java installation until the star of mule server.
Choose the exact line between the download of mule and the start of server and put a sentence which replace the jar file
Next deploy will pick you new image version and that's all.
automated flow(devops)
Here you are using maven, gi, docker and some ci server. You just need:
update the git repository of your mule app (maven)
update the git repository of your docker image
deploy your fix using the ci server.
With this, you will not need human access to the production servers to fix your java application ( mule)
We want to embed mule community edition 4.x is our war file. Is there a sample anywhere showing this. With Mule 3x we used the MuleXmlBuilderContextListener.
UPDATE:
I added the mule repositories to my settings.xml as mentioned in the mule documention. I am referencing 4.1.4 and the different mule jar files I need are available except for the builders. I am trying to initialize the mule with the org.mule.runtime.config.builders.MuleXmlBuilderContextServlet passing in the location of the mule context.
When I look for that class in the mule repositories, the latest version I find is here:
<dependency>
<groupId>org.mule.runtime</groupId>
<artifactId>mule-module-builders</artifactId>
<version>4.0.0-FD.4</version>
</dependency>
and during startup I see some errors in comparability. Does anyone know where in the mule repositories I can find version 4.1.4 of the mule-module-builders atrifact?
I need to setup https://github.com/adminfaces but i can't make it work at all. I get errors in wildfly deployment.
I setup intellij project, i select framework support for JSF, and Primefaces which are prerequisites. But than docs say:
Add admin theme to your classpath:
<dependency>
<groupId>com.github.adminfaces</groupId>
<artifactId>admin-theme</artifactId>
<version>1.0.0-RC9</version>
</dependency>
How do i do this if i don't use maven? Can i set it up, via some jar file. Also i don't get it, if i download release from github, what is install.sh?
But even if i added it through maven via Intellij browser it still doesn't work. Can't deploy to Wildfly.
Maven library can be added to non Maven project through Intellij IDEA.
Project structure->Libraries->Add library->From Maven
AdminFaces jars are published to maven central, you can download it there, see here.
Just add admin-template and admin-theme to your classpath.
Also it depends on OmniFaces (2.x) and PrimeFaces (5.1.1 or greater) and also JavaEE apis such as servlet, EJB, CDI, JSF and JPA.
If you are running it outside a JavaEE container such as Tomcat take a look at Admin Starter Tomcat dependencies, you should be able to download them from maven central as well.
I'm on Arch linux x64 machine , I installed intellij idea but whenever I open a project a startupabortedexception occurs with the JavaDoc browser plugin.
I looked into my idea.log and figured out that it can't find javax.servlet.Servlet, I disabled the plugin in order to open a java project and indeed when I type import javax; it says it can't find javax.
I have java-openjfx installed and still intellij can't find it, what to do in this case ? .
Environment information
jdk:openjdk 1.8.0_60 64 bit.
intellij version: 14.1.5 community edition.
Goal
My goal is to get the JavaDoc browser plugin to work not to program in javax.servlet, I don't intend to do any web development with java right now.
If you don't have Maven project, you can just add the jar to the project. The one you are missing can be downloaded from:
http://mvnrepository.com/artifact/javax.servlet/javax.servlet-api/3.1.0
(just click "Download (JAR)" button)
The class javax.servlet.Servlet is not part of the standard JDK, it is part of the JEE, so you have to add servlet-api.jar to your classpath.
If your project is a Maven project you add the dependency like this:
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.1.0</version>
</dependency>
And you probably want to add
<scope>provided</scope>
as this dependency is most likely present in your application server.
i'm very new to mule esb. I have some question after try mule.
1.how can i run mule project by Tomcat? (I've try this issue but seem not working : http://www.mulesoft.org/documentation/display/current/Deploying+Mule+as+a+Service+to+Tomcat)
I have error when I starting tomcat like something was wrong.
2.How can I packing mule project to .war? ,I see that my editor(sts) don't think that mule application is a web application but the file path of mule application seem to be similar to maven generate project so... I don't know.
I use mule version 3.4.0
thank you,
First of all, you should use the Mule Standalone, if you can. If you really need to use Tomcat, I suggest you package all the Mule dependencies into the application war with Maven, and not try to work with the jars manually. See the answer by David Dossot here and an example Maven project here. Note that the example project uses Mule 3.1.2, so you probably want to update it a bit.
