An example to use while trying to upload files. This is one possible approach with out saving blobs. You will use the file system to store the files and use a database table to hold references to them. You will also see here how one can display the files.

1. You will be using commons file upload plugin or part

2. You will need to add a url rewrite filter that comes with aspire to convert extra path to url arguments

3. You will "singlefileuploadpart" to parse the multipart upload

4. You will use a PSExecutor2 part to save it as a blob in the database

5. You can BlobTransform to write it back to the browser

This is an important read to configure aspire for uploading files

Generic mappers are a set of java classes used to quickly read key value pairs. For example the relationship between file extension and their content type is determined this way.

This mechanism is intended to be a general purpose mechanism for reading a dictionary of values

The current implementation is a bit inefficient but a future implementation can amend that.

This class allows you to use connection pools from apache or tomcat

This class implements a mechanism to preload a certain number of connections for each data source. The facility also allows to keep those many minimum connections open during the clean up process.

Some important log search strings

DatabaseTM: log file for single select

Description to be entered

Aspire not only allows you to access and update data using stored procedures but also allows additional features to use stored procedures as the business layer. Here are a few things where and how stored procedures could be used in Aspire

request.putVariable2InSession.classname=com.ai.parts.SessionVariablesPart
request.putVariable2InSession.variableName=var1
request.putVariable2InSession.newVariableName=var2

The above code when embedded in a pipeline will take "var1" from the hashtable and places it in the session as "var2". If newVariableName is not mentioned then it will just put it as variableName

1. you can turn off flushing and closing the stream in base servlet

2. You can use JSPIncludeTransform to include jsp urls

you can use this part for introducing or copying existing keys as new keys.

When some people have tried to install loginapp4, they ran into some issues. Tomcat itself threw an exception while loading the context for loginapp4.

See if you can comment out the following line in aspire.properties

aspire.systemProperties

use a # at the begining

A way to construct hds on the fly: an example using Lucene

Updates are quite straight forward in Aspire. An update is initiated by a user submitting a form. A form can be submitted using either a get method or a post method. Or you can even use a javascript function to collect the relevent fields and fire of a URL to the server along with the parameters.
