Im getting the next error when I try to load "sidepanel.jelly" in my Jenkins plugin action jelly file.

My jelly file has the following lines

</l:main-panel>
</l:layout>
</j:jelly>
Any idea how can I fix it?
Thanks!
Add the <l:main-panel> tag and the the <l:layout norefresh="true">tag to the index.jelly file.
And include the side panel:
Pass the the build to Action (through a parameter of the constructor)
The build can be retrieved out of the parameters of the perform method which is inherited from the BuildStepCompatibilityLayer class (by Extending Publisher).
Create a getBuild() method in the Action class
Add the <st:include it="${it.build}" page="sidepanel.jelly" /> tag with the build
Jelly Example (index.jelly):
<j:jelly xmlns:j="jelly:core" xmlns:st="jelly:stapler" xmlns:d="jelly:define" xmlns:l="/lib/layout" xmlns:t="/lib/hudson" xmlns:f="/lib/form" xmlns:i="jelly:fmt" xmlns:p="/lib/hudson/project">
<l:layout norefresh="true">
<st:include it="${it.build}" page="sidepanel.jelly" />
<l:main-panel>
<f:validateButton title="${%Restart Jenkins}" progress="${%Restarting...}" method="JksRestart" with="" />
</l:main-panel>
</l:layout>
</j:jelly>
Java Action class example:
package tryPublisher.tryPublisher;
import hudson.model.Action;
import hudson.model.AbstractBuild;
public class ExampleAction implements Action {
AbstractBuild<?,?> build;
public ExampleAction(AbstractBuild<?,?> build) {
this.build = build;
}
#Override
public String getIconFileName() {
return "/plugin/action.png";
}
#Override
public String getDisplayName() {
return "ExampleAction";
}
#Override
public String getUrlName() {
return "ExampleActionUrl";
}
public AbstractBuild<?,?> getBuild() {
return this.build;
}
}
Java Publisher class example:
package tryPublisher.tryPublisher;
import java.io.IOException;
import hudson.Launcher;
import hudson.model.AbstractBuild;
import hudson.model.BuildListener;
import hudson.tasks.BuildStepMonitor;
import hudson.tasks.Publisher;
public class ExamplePublisher extends Publisher {
#Override
public BuildStepMonitor getRequiredMonitorService() {
return BuildStepMonitor.NONE;
}
#Override
public boolean perform(AbstractBuild<?, ?> build, Launcher launcher,
BuildListener listener) throws InterruptedException, IOException {
build.getActions().add(new ExampleAction(build));
return true;
}
}
The .jelly file has to be in the right resources map of the plugin project. In a map with the same name as the name of the Java class implementing Action. The name of the .jelly is important also.

I am using Spring and Thymeleaf. Thanks to xerx593, I was able to get it working so I updated this question to show the working code.
Here is my application class
package com.propfinancing.www;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.context.annotation.Bean;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import nz.net.ultraq.thymeleaf.layoutdialect.LayoutDialect;
#Controller
#SpringBootApplication
public class PfWebApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(PfWebApplication.class, args);
}
#Bean
public LayoutDialect layoutDialect() {
return new LayoutDialect();
}
#GetMapping("/page1.html")
public String page1() {
return "page1";
}
}
Next, I create a layout.html file in src/main/resources/templates/layout.html
<!DOCTYPE html>
<html lang="en" xmlns:layout="http://www.ultraq.net.nz/thymeleaf/layout">
<body>
This is the layout template
<div layout:fragment="content">
<p>This is were the content will go</p>
</div>
</body>
</html>
And fin
ally, I created /ser/main/resources/templates/page1.html to use the template:
<!DOCTYPE html>
<html lang="en"
xmlns:layout="http://www.ultraq.net.nz/thymeleaf/layout"
layout:decorate="~{layout}">
<body>
<div layout:fragment="content">
This is the content of page 1.
</div>
</body>
</html>
When I go to http://dev.propfinancing.com/www/page1.html, it gives me the template driven output I was expecting.
Thanks!
Neil
The most obvious mistake:
I created a simple html page called page1.html in my src/main/resources/static directory
(This is super for (spring-web) static content, but...)
And finally, I updated my page1.html to use the template...
Updating is not enough, you have to also move it to a configured template location! So moving the file to src/main/resources/templates/ (default location, issuing same browser request,) will hopefully/probably produce the desired result(, or at least throw an exception).
In short: src/main/resources/static directory is not intended for templates! (It can still be configured, but this would be very strange/hacky/bunch full of "side effects"!?).
Ok, the 404, can be fixed (simply) with:
#Controller // !
#SpringBootApplication
public class ThymeleafTestApplication {
public static void main(String[] args) {
SpringApplication.run(ThymeleafTestApplication.class, args);
}
#GetMapping("/page1.html") // !!
public String page1() {
return "page1"; // returning the view name
}
// ...
}
i.e. by providing a "controller" for this "view".
Or by configuring:
#SpringBootApplication
public class PfWebApplication // extends ...
implements WebMvcConfigurer {
#Override
public void addViewControllers (ViewControllerRegistry registry) {
ViewControllerRegistration r = registry.addViewController("/page1.html");
r.setViewName("page1");
// r.set...
}
...
One important thing is, that:
#Bean
public LayoutDialect layoutDialect() {
return new LayoutDialect();
}
is the "auto-configuration" approach, which equips us with "all the spring (boot) magic".
Whereas:
#Bean
public SpringTemplateEngine templateEngine() {
SpringTemplateEngine templateEngine = new SpringTemplateEngine();
templateEngine.addDialect(new LayoutDialect());
return templateEngine;
}
..is the "DIY" approach, and we'd have to tune (like e.g. spring-boot does).
Links:
https://ultraq.github.io/thymeleaf-layout-dialect/
https://docs.spring.io/spring-boot/docs/current/reference/html/web.html#web
https://www.thymeleaf.org/doc/articles/layouts.html
In my case the problem was in the use of decorator I solved this issue by simply changing decorator to decorate
Here I had the error when I used decorator to configure the created template using Thymeleaf
<html xmlns:th="http://www.thymeleaf.org"
xmlns:layout="http://www.ultraq.net.nz/thymeleaf/layout"
layout:decorator="template1">
Then I changed the decorator keyword to decorate and it just worked fine :
<html xmlns:th="http://www.thymeleaf.org"
xmlns:layout="http://www.ultraq.net.nz/thymeleaf/layout"
layout:decorate="template1">

1) You have MySQL connection exception as below:
Establishing SSL connection without server's identity verification is not recommended.
According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set.
To resolve this use the connection string like below:(change the db name to your existing db name)
jdbc:mysql://localhost:3306/dbname?autoReconnect=true&useSSL=false
This needs to be sorted first, that's why the values of the variables are not been rendered
2) In the Latest trace the requested list key 'projectidList' could not be resolved as a collection/array/map/enumeration/iterator type.
This error occurs when you try to access a list/collection which haven't been created.
Try to initialize the collection objects List<String> projectidList at class level.
when particular action is triggered at that time, JSP page is not knowing the the type of field, in this case, when you write List<String> projectidList = new ArrayList<String>(); instead of this, change it to ArrayList projectidList = new ArrayList();.
Make sure that you access list after the action class is instantiated i.e. corresponding action is called.
If you want to directly access it before calling action make it static and access it inside jsp.
This is my Assignemployee.jsp file code
<s:form action="AssignEmployee" name="myForm">
<s:select name="pname" list="projectlist" headerKey="0" label="Select a country" />
<s:submit/>
</s:form>
This is my projectlist.java action file
package myPack;

import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import org.apache.struts2.interceptor.ApplicationAware;
import org.apache.struts2.interceptor.ServletRequestAware;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.Preparable;
public class projectlist extends ActionSupport implements ServletRequestAware {
private static final long serialVersionUID = 1L;
HttpServletRequest request;
private List<String> projectlist;
public List<String> getProjectlist() {
return projectlist;
}
public void setProjectlist(List<String> projectlist) {
this.projectlist = projectlist;
}
public void setServletRequest(HttpServletRequest request)
{
this.request = request;
}
public HttpServletRequest getServletRequest(){
return request;
}
public String getDefaultSearchEngine() {
return "yahoo.com";
}
public projectlist()
{
try
{
Class.forName("com.mysql.jdbc.Driver");
java.sql.Connection con=DriverManager.getConnection("jdbc:mysql:///pmt","root","shree");
ps=con.prepareStatement("select * from addproject");
ResultSet res = ps.executeQuery();
while(res.next())
{
projectlist = new ArrayList<String>();
projectlist.add(res.getString("pname"));
}
ps.close();
con.close();
}
catch(Exception e)
{
e.printStackTrace();
}
}
public String execute()throws Exception

}
And This is struts.xml

<result name="success">assignemployee.jsp</result>
</action>
When i am running application i get an error like
SEVERE: Servlet.service() for servlet [jsp] in context with path [/PTMS] threw exception [tag 'select', field 'list', name 'pname': The requested list key 'projectlist' could not be resolved as a collection/array/map/enumeration/iterator type. Example: people or people.{name} - [unknown location]] with root cause
tag 'select', field 'list', name 'pname': The requested list key 'projectlist' could not be resolved as a collection/array/map/enumeration/iterator type. Example: people or people.{name} - [unknown location]
How to solve this error?
There are two problems:
Project list creation is broken, and
The first access to the form is broken.
1) You're creating a new list for every row in the result set:
while (res.next()) {
projectlist = new ArrayList<String>();
projectlist.add(res.getString("pname"));
}
This should look closer to:
projectlist = new ArrayList<String>();
while (res.next()) {
projectlist.add(res.getString("pname"));
}
It also appears you never actually call this method, although it's difficult to tell since the code is essentially illegible without indentation or any valuable whitespace. Where you call it is open to some debate; it could be in the getter itself, a prepare() method (and the action would implement Prepareable), the execute() method, etc.
These kinds of things should likely go into a service, however, as a testability aid.
2) I'm not convinced your initial visit to the JSP is being handled correctly. It should:
a) Go through a Struts 2 action,
b) Call the projectlist initializer, and
c) Forward to the JSP with the form.
If all those criteria are met, you will not get that error.

I am not able to figure out where i went Wrong.Please help me.
How did you come to using #{x.fileName}? Look carefully in the javadoc of the java.io.File class. Right, there's no such method like getFileName(). That's exactly what the exception is trying to tell you.
value="#{x.fileName}": Property 'fileName' not found on type java.io.File
Most likely you meant to use the getName() method instead.
#{x.name}
Unrelated to the concrete problem, your code would be more self-documenting if you used var="file" instead of the nonsensicial var="x".
I'm using JBoss6.1.Final, JSF 2.0 (Mojarra), Weld CDI, MyFaces CODI 1.0.5 (for view-access-scoped)
I'm using something like the Gateway Pattern from Real World Java EE Patterns Rethinking Best Practices (unfortunately I don't have it with me, so I may have screwed something up here). Basically, the application allows a user to go into "edit mode" and edit a List of people (create, edit, remove) maintained in a #ViewAccessScoped backing bean with an extended persistence context and then click a "save" command link that flushes all their changes to the database. At first I was having a problem with ViewExpiredExceptions (if the browser was idle past the session-timeout period and then further requests are performed), but I added some jQuery to make a get request to a servlet that keeps the session alive (called 10 seconds before session-timeout). This seems to be working but now I have another problem, the backing bean is also a SFSB and after some idle time, it is being removed resulting in the following error message being logged (and all ajax rendered data disappears) when I attempt to perform more edits ...
13:06:22,063 SEVERE [javax.enterprise.resource.webcontainer.jsf.context] javax.el.ELException: /index.xhtml #27,81 rendered="#{!conversationBean.editMode}": javax.ejb.NoSuchEJBException: Could not find stateful bean: 43h1h2f-9c7qkb-h34t0f34-1-h34teo9p-de
Any ideas on how I could prevent SFSB removal or at least handle it more gracefully?

Here's a servlet used to keep the session alive (called by jQuery ajax get request 10 seconds before session expires):
package com.ray.web;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class PollServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
public void init() throws ServletException {
}
public String getServletInfo() {
return null;
}
public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException {
request.getSession(); //Keep session alive
}
public void doPost(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException {
}
public void destroy() {
}
}
Any ideas on how I could prevent SFSB removal or at least handle it
more gracefully?
To investigate further I would recommend to take a look at the EJB lifecycle hooks for passivation and add some debug output there.
Should that be the source of the problem you will be able to configure / deactivate passivation - but scalability might come up as an issue.
Honestly, this scenario seems quite uncommon to me. In general I would expect requests / conversations / sessions to be working more or less in the default boundaries - should you find yourself writing code that circumvents this can it be that you are better off with a RESTful / stateless approach...?
Please update the question with further information if available.
I suppose you have already solved your problem. Otherwise, this JBoss wiki page should be helpful (also for future readers...).
