jBPM6中的文件自定义字段类型

法尔达·穆萨（Fardad Moosae）

实际上，我正在尝试向任务表单添加文件字段类型，以便用户可以在任务表单中上载文件。

我做相应的程序：

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

4）ant install.demo

5）ant start.demo

但是不幸的是我遇到了部署失败的错误，这里是：

如果我想念什么，您能帮我吗？？？

哈萨巴拉

发生此问题的原因是在两个不同的jar中有两个具有相同名称（fdch）的bean

（jbpm-form-modeler-custom-file-type.jar）和您的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

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