Question

实际上，我正在尝试将文件字段类型添加到任务表单中，用户可以在任务表单中上传任务表单中的文件。

我做了相应的程序：

1）ant clean.demo

2）添加“文件输入”：new org.jbpm.formModeler.core.fieldTypes.file.FileCustomType（）tp jBPM-installer / conf / META-INF / CustomWorkItemHandlers.conf

3）将cutomFieldType.jar（包括以下https://github.com/droolsjbpm/jbpm-form-modeler/tree/master/jbpm-form-modeler-sample-custom-types/jbpm-form-modeler-custom-file-type的构建。）添加到WEB / lib

4）ant install.demo

5）ant start.demo

但不幸的是我面临部署失败这是错误：

如果我错过了什么，你能帮助我吗？

Answer 1

出现此问题是因为在两个不同的jar中有两个名称相同的bean（fdch）

（jbpm-form-modeler-custom-file-type.jar）和你的jar（cutomFieldType.jar）

您需要将此类的bean名称更改为另一个名称，例如（@Named（“mybean”））

https://github.com/droolsjbpm/jbpm-form-modeler/blob/master/jbpm-form-modeler-sample-custom-types/jbpm-form-modeler-custom-file-type/src/main/java/org/jbpm/formModeler/core/fieldTypes/file/FileDownloadHandler.java

或者你可以从web-inf \ ib中删除jbpm-form-modeler-custom-file-type.jar

在jBPM6中归档自定义字段类型
