Method Detail

invokeTemplateFromInlineString

public static java.lang.String invokeTemplateFromInlineString(java.lang.String templateString)
                                                       throws com.ebasetech.xi.exceptions.FormRuntimeException

This is equivalent to invoking method invokeTemplateFromInlineString(String, int) with log level warn.

Throws:

com.ebasetech.xi.exceptions.FormRuntimeException

Since:

V4.4

invokeTemplateFromInlineString

public static java.lang.String invokeTemplateFromInlineString(java.lang.String templateString,
                                                              int logLevel)
                                                       throws com.ebasetech.xi.exceptions.FormRuntimeException

Invokes the Velocity template contained in parameter templateString. This provides integration with the Velocity template engine supplied by Apache.

The logging level controls the level of generated messages, and any such messages are written to the designer execution log (View > Execution log). Available log levels are:

• 0 debug (constant LOG_LEVEL_DEBUG)
• 1 info (constant LOG_LEVEL_INFO)
• 2 warn (constant LOG_LEVEL_WARN)
• 3 error (constant LOG_LEVEL_ERROR)

Further documentation.

Javascript example:

 var template = "<table border='0'> " +
   "#foreach ( $row in $ORDERS ) " +
   "<tr> " +
     "<td>Order Number: ${ORDERS-ORDER_NUMBER}</td>" +
     "<td>Order Value: ${ORDERS-ORDER_VALUE}</td> " +
   "</tr> " +
   "#end " +
   "</table>";
 fields.RESULT.value = VelocityServices.invokeTemplateFromInlineString(template, VelocityServices.LOG_LEVEL_WARN);
 

Parameters:

templateString - the Velocity template string

logLevel - see above

Returns:

the result of executing the template

Throws:

com.ebasetech.xi.exceptions.FormRuntimeException - if any error occurs

Since:

V4.4

invokeTemplateFromFile

public static java.lang.String invokeTemplateFromFile(java.lang.String fileName)
                                               throws com.ebasetech.xi.exceptions.FormRuntimeException

This is equivalent to invoking method invokeTemplateFromFile(String, int) with log level warn.

Throws:

com.ebasetech.xi.exceptions.FormRuntimeException

Since:

V4.4

invokeTemplateFromFile

public static java.lang.String invokeTemplateFromFile(java.lang.String fileName,
                                                      int logLevel)
                                               throws com.ebasetech.xi.exceptions.FormRuntimeException

Invokes the Velocity template contained in the file specified by fileName. This provides integration with the Velocity template engine supplied by Apache.

Only a file name can be specified for the template location, not a complete file path. All templates must be located in the directory specified in parameter file.resource.loader.path of properties file velocity.properties.

The logging level controls the level of generated messages, and any such messages are written to the designer execution log (View > Execution log). Available log levels are:

• 0 debug (constant LOG_LEVEL_DEBUG)
• 1 info (constant LOG_LEVEL_INFO)
• 2 warn (constant LOG_LEVEL_WARN)
• 3 error (constant LOG_LEVEL_ERROR)

Javascript example:

 fields.F1.value = VelocityServices.invokeTemplateFromFile("template1.vm", VelocityServices.LOG_LEVEL_DEBUG);
 

Parameters:

fileName - the file name of the Velocity template

logLevel - see above

Returns:

the result of executing the template

Throws:

com.ebasetech.xi.exceptions.FormRuntimeException - if any error occurs
