Question

I have a jasper report with a field $F{fupgrade_package_name}

so when I run my query upgrade_package_name is set to http://www.something.com/file.exe

I want to only display file.exe in the report and not the full URL.

How is this done?

Thanks

You can use this expression:

<parameter name="url" class="java.lang.String" isForPrompting="false">
    <defaultValueExpression><![CDATA["http://www.something.com/file.exe"]]></defaultValueExpression>
</parameter>

<textField>
    <reportElement x="122" y="28" width="100" height="20"/>
    <textElement/>
    <textFieldExpression>
        <![CDATA[$P{url}.contains("/") ? $P{url}.split("/")[$P{url}.split("/").length-1] : $P{url}]]></textFieldExpression>
</textField>

The result will be:

file.exe

And for the url = "just_file_wout_url.txt" the result will be:

just_file_wout_url.txt

For your case the expression will be:

$F{fupgrade_package_name}.contains("/") ? $F{fupgrade_package_name}.split("/")[$F{fupgrade_package_name}.split("/").length-1] : $F{fupgrade_package_name}
