# Upload File

During Microflow or Process Flow development, users often need to reference **external files** such as:

* **JAR files** for **Java Tasks**
* **WSDL / XSD files** for **Web Service Tasks**

Instead of uploading these files individually at each node, ONEWEB provides an **Upload File facility** at the **application level**.\
Uploaded files can then be reused and referenced across multiple nodes and flows.

This approach simplifies **file management**, version control, and maintenance.

***

### Purpose of Upload File Facility

Using the Upload File feature allows users to:

* Centralize management of shared artifacts
* Reuse the same JAR or WSDL file across multiple flows
* Update files without modifying individual node configurations
* Reduce duplication and configuration errors

This is especially useful in enterprise‑scale integrations where multiple Microflows depend on the same libraries or service definitions.

***

### Upload Files to an Application

To upload files for use in Microflows or Process Flows:

1. Open the application in **AppSpace**
2. Navigate to the **Upload Files** menu
3. Upload the required files:
   * Java JAR files
   * WSDL / XSD files
   * Other supported artifacts

Once uploaded, the files are stored at the **application level** and become available for selection in relevant node configurations.

***

### Using Uploaded Files in Node Tasks

After uploading files, users can reference them directly from node configuration panels.

#### Java Task

* Open the **Java Task** configuration
* Select the required **JAR file** from the list of uploaded files

***

#### Web Service Task

* Open the **Web Service Task** configuration
* Choose the uploaded **WSDL / XSD file** from the dropdown or selection dialog

### Benefits of Centralized File Upload

Using the Upload File facility provides several benefits:

* **Ease of maintenance**\
  Updating a file automatically affects all nodes referencing it.
* **Consistency**\
  Ensures all flows use the same version of an artifact.
* **Reusability**\
  One file can be reused across multiple Microflows or Processes.
* **Cleaner configuration**\
  Node configurations remain simple and focused on logic, not file management.

***

### Best Practices

* Upload shared JAR and WSDL files at the application level
* Use meaningful file names and maintain versioning discipline
* Avoid embedding JAR files directly inside multiple Java Nodes
* Update uploaded files carefully to avoid unexpected runtime impact
* Validate flows after updating shared artifacts

***

### Summary

The **Upload File** feature in ONEWEB allows developers to manage external artifacts centrally and reuse them across Microflows and Process Flows.

With this capability, users can:

* Upload JAR and WSDL files once per application
* Reference them easily from Java and Web Service nodes
* Simplify maintenance and updates
* Build cleaner, more maintainable integration flows

This feature is an important support mechanism for building **scalable and enterprise‑grade integrations** using ONEWEB Microflow.
