How to add graph to jsp

Hi!

I want to show several graphs for different projects on my custom page.

I'm new to TeamCity plugins development, so I started from https://confluence.jetbrains.com/display/TCD9/Custom+Statistics

To insert statistics chart into a jsp page:


<%@taglib prefix="stats" tagdir="/WEB-INF/tags/chart"%>

<stats:buildChart id="g1" valueType="BuildDuration"/>

But this is obsolete information for TC9.

Can anybody show a simple example displaying graph? Or any additional info about graphs?

Ok, i can add graph to Statistics tab with SimplePageExtension and:

<stats:buildGraph id="TestGraph" valueType="BuildDuration" />

But how to display it on custom page, provided by BaseController?

package ru.mail.teamcity.plugin.customstats;

import jetbrains.buildServer.controllers.BaseController;
import jetbrains.buildServer.serverSide.ProjectManager;
import jetbrains.buildServer.serverSide.SProject;
import jetbrains.buildServer.web.openapi.PluginDescriptor;
import jetbrains.buildServer.web.openapi.WebControllerManager;
import org.jetbrains.annotations.NotNull;
import org.jetbrains.annotations.Nullable;
import org.springframework.web.servlet.ModelAndView;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.List;

public class AppServer extends BaseController {
    @NotNull
    private static final String PATH_TO_JSP = "Hello.jsp";
    @NotNull
    private final PluginDescriptor myDescriptor;
    @NotNull
    private final ProjectManager projectManager;

    public AppServer(@NotNull WebControllerManager manager,
                     @NotNull PluginDescriptor descriptor,
                     @NotNull ProjectManager projectManager) {
        this.projectManager = projectManager;
        manager.registerController("/customstats.html",this);
        myDescriptor = descriptor;
    }

    @Nullable
    @Override
    protected ModelAndView doHandle(@NotNull HttpServletRequest httpServletRequest,
                                    @NotNull HttpServletResponse httpServletResponse) throws Exception {
        final List<SProject> activeProjects = projectManager.getActiveProjects();

        final SProject sProject = activeProjects.get(0);

        final ModelAndView modelAndView = new ModelAndView(myDescriptor.getPluginResourcesPath(PATH_TO_JSP));

        modelAndView.getModel().put("activeProjects", activeProjects);
        modelAndView.getModel().put("buildTypes", sProject.getBuildTypes());

        return modelAndView;
    }
}

Hello.jsp:

<%@ page contentType="text/html;charset=UTF-8" language="java" session="true"
  %><%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"
  %><%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt"
  %><%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions"
  %><%@taglib prefix="stats" tagdir="/WEB-INF/tags/graph"
  %><%@taglib prefix="bs" tagdir="/WEB-INF/tags"
  %>

<jsp:useBean id="activeProjects" scope="request" type="java.util.List<jetbrains.buildServer.serverSide.SProject>"/>
<jsp:useBean id="buildTypes" scope="request" type="java.util.List<jetbrains.buildServer.serverSide.SBuildType>"/>

<html>
<body>
    <select id="project">
        <c:forEach var="project" items="${activeProjects}">
          <option value="${project.getProjectId()}">
              ${project.getName()}
          </option>
        </c:forEach>
    </select>

    <select id="buildType">
        <c:forEach var="buildType" items="${buildTypes}">
          <option value="${buildType.getBuildTypeId()}" qqq="${buildType.getExternalId()}">
              ${buildType.getName()}
          </option>
        </c:forEach>
    </select>

    <br>
    <c:forEach var="buildType" items="${buildTypes}">
        <stats:buildGraph id="HelloGraph_${buildType.getExternalId()}"
                          valueType="BuildDuration"
                          buildTypeExternalId="${buildType.getExternalId()}"
                          projectExternalId="${buildType.getProject().getExternalId()}"
                          />
    </c:forEach>
</body>
</html>

Unfortunatly page throws NPE in stats:buildGraph.

How to understand whats wrong? Any ideas?

Hi Dmitrii,

The problem is that <buildGraph> requires BuildGraphHelper bean in the model. It isn't in the openapi, however there is a simple way to get it - there is special controller accessible on "/buildGraph.html" which provides the bean. It requires only "jsp" attribute leading to your page. Somewhat like this should work:

 <bs:page>
  <jsp:attribute name="body_include">
          <!-- The page contents (without html and body tags) --> 
  </jsp:attribute>
</bs:page>

Yeap, this documentation is really outdated. We will update it.

Thanks! It works with

final ModelAndView modelAndView = new ModelAndView("/buildGraph.html?jsp=" + myDescriptor.getPluginResourcesPath(PATH_TO_JSP))
