Question

我收到以下错误

java.lang.IllegalStateException: Unable to determine the default workspace location.  Check your OSGi-less platform configuration of the plugin or datatools workspace path.

这没什么意义。

使用Eclipse中的BIRT设计器创建报告，我们使用代码将报告转换为PDF。

代码看起来像

    final EngineConfig config = new EngineConfig();
    config.setBIRTHome("./birt");
    Platform.startup(config);
    final IReportEngineFactory factory = (IReportEngineFactory) Platform
            .createFactoryObject(IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY);

    final HTMLRenderOption ho = new HTMLRenderOption();
    ho.setImageHandler(new HTMLCompleteImageHandler());
    config.setEmitterConfiguration(RenderOption.OUTPUT_FORMAT_HTML, ho);
    // Create the engine.
    this.engine = factory.createReportEngine(config);
    final IReportRunnable report = this.engine.openReportDesign(reportName);
    final IRunAndRenderTask task = this.engine.createRunAndRenderTask(report);
    final RenderOption options = new HMTLRenderOption();
    options.setOutputFormat(HTMLRenderOption.OUTPUT_FORMAT_PDF);
    options.setOutputFormat("pdf");
    final String output = reportName.replaceFirst(".rptdesign", ".xls");
    final String output = name.replaceFirst(".rptdesign", "." + HTMLRenderOption.OUTPUT_FORMAT_PDF);
    options.setOutputFileName( outputReporttName);
    task.setRenderOption(options);


    // Run the report.
    task.run();

但是在 task.run（）方法中，系统会抛出错误。

这需要能够独立运行，而不需要eclipse，并且跳过它设置BIRT home会让它开心，但这些似乎是我不知道的其他连接配置文件，可能不需要

有没有人看过这个错误，可以指出我正确的方向？

Answer 1

当我遇到这个问题时，我尝试了两件事。第一件事解决了错误，但后来我才得到了下一个错误。

我尝试的第一件事是将setenv.sh文件设置为具有以下行： export CATALINA_OPTS="$CATALINA_OPTS -Djava.io.tmpdir=/opt/local/share/tomcat/apache-tomcat-8.0.8/temp/tmpdir -Dorg.eclipse.datatools_workspacepath=/opt/local/share/tomcat/apache-tomcat-8.0.8/temp/tmpdir/workspace_dtp"

此解决方案在我在本地tomcat服务器中创建tmpdir和workspace_dtp目录后起作用。这是为了响应指导here。

但是，我刚刚接到下一个错误，这是一个连接配置文件错误。如果你需要，我可以再次调查一下。我知道如何复制这个问题。

我尝试的第二件事最终完全解决了这个问题，并且与我们的报表设计师在报表设计过程中选择错误类型的数据源有关。有关完整故事，请参阅Eclipse BIRT论坛上的帖子：post。

基本上，当报表类型设置为“JDBC数据源”时，报表类型设置为“查询生成器的JDBC数据库连接”。请参阅图片以供参考： New Data Source window in Eclipse BIRT New Data Source Wizard

Answer 2

在这里，我给你一个提示，让我免于痛苦： 安装BIRT插件后，只需使用“-clean”选项启动eclipse。

要清楚，我的项目是基于BIRT maven依赖项构建的，所以不应该使用eclipse依赖项来运行（除了设计报告），但是......我认为某处存在冲突...尤其是与org。 eclipse.datatools.connectivity_1.2.4.v201202041105.jar

要获得全球理解，您应该遵循迁移指南： http://wiki.eclipse.org/Birt_3.7_Migration_Guide#Connection_Profiles

它有助于使用连接配置文件外部化数据源参数。因此，如果直接在报表设计中定义JDBC参数，则不需要这样做。

我使用这种编程方式初始化工作区目录：

@Override
public void initializeEngine() throws BirtException {
    // define eclipse datatools workspace path (required)
    String workspacePath = setDataToolsWorkspacePath();

    // set configuration
    final EngineConfig config = new EngineConfig();
    config.setLogConfig(workspacePath, Level.WARNING);

    // config.setResourcePath(getSqlDriverClassJarPath());

    // startup OSGi framework
    Platform.startup(config); // really needed ?
    IReportEngineFactory factory = (IReportEngineFactory) Platform
            .createFactoryObject(IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY);
    engine = factory.createReportEngine(config);
    engine.changeLogLevel(Level.WARNING);
}

private String setDataToolsWorkspacePath() {
    String workspacePath = System.getProperty(DATATOOLS_WORKSPACE_PATH);
    if (workspacePath == null) {
        workspacePath = FilenameUtils.concat(SystemUtils.getJavaIoTmpDir().getAbsolutePath(), "workspace_dtp");
        File workspaceDir = new File(workspacePath);
        if (!workspaceDir.exists()) {
            workspaceDir.mkdir();
        }
        if (!workspaceDir.canWrite()) {
            workspaceDir.setWritable(true);
        }
        System.setProperty(DATATOOLS_WORKSPACE_PATH, workspacePath);
    }
    return workspacePath;
}

我还需要在运行时以这种方式强制数据源参数：

private void generateReportOutput(InputStream reportDesignInStream, File outputFile, OUTPUT_FORMAT outputFormat,
        Map<PARAM, Object> params) throws EngineException, SemanticException {
    // Open a report design
    IReportRunnable design = engine.openReportDesign(reportDesignInStream);

    // Use data-source properties from persistence.xml
    forceDataSource(design);

    // Create RunAndRender task
    IRunAndRenderTask runTask = engine.createRunAndRenderTask(design);

    // Use data-source from JPA persistence context
    // forceDataSourceConnection(runTask);

    // Define report parameters
    defineReportParameters(runTask, params);

    // Set render options
    runTask.setRenderOption(getRenderOptions(outputFile, outputFormat, params));

    // Execute task
    runTask.run();
}

private void forceDataSource(IReportRunnable runableReport) throws SemanticException {
    DesignElementHandle designHandle = runableReport.getDesignHandle();

    Map<String, String> persistenceProperties = PersistenceUtils.getPersistenceProperties();
    String dsURL = persistenceProperties.get(AvailableSettings.JDBC_URL);
    String dsDatabase = StringUtils.substringAfterLast(dsURL, "/");
    String dsUser = persistenceProperties.get(AvailableSettings.JDBC_USER);
    String dsPass = persistenceProperties.get(AvailableSettings.JDBC_PASSWORD);
    String dsDriver = persistenceProperties.get(AvailableSettings.JDBC_DRIVER);

    SlotHandle dataSources = ((ReportDesignHandle) designHandle).getDataSources();
    int count = dataSources.getCount();
    for (int i = 0; i < count; i++) {
        DesignElementHandle dsHandle = dataSources.get(i);
        if (dsHandle != null && dsHandle instanceof OdaDataSourceHandle) {
            // replace connection properties from persistence.xml
            dsHandle.setProperty("databaseName", dsDatabase);
            dsHandle.setProperty("username", dsUser);
            dsHandle.setProperty("password", dsPass);
            dsHandle.setProperty("URL", dsURL);
            dsHandle.setProperty("driverClass", dsDriver);
            dsHandle.setProperty("jarList", getSqlDriverClassJarPath());
            // @SuppressWarnings("unchecked")
            // List<ExtendedProperty> privateProperties = (List<ExtendedProperty>) dsHandle
            // .getProperty("privateDriverProperties");
            // for (ExtendedProperty extProp : privateProperties) {
            // if ("odaUser".equals(extProp.getName())) {
            // extProp.setValue(dsUser);
            // }
            // }
        }
    }
}
