[Former Member]

hi

iam trying to send table data to excel sheet where

the user can choose the location he can store the file.

https://www.sdn.sap.com/irj/sdn/wiki?path=/display/snippets/webDynproJava-ExportingTableDataUsingOn-DemandStreams-SAPNW+7.0

i have gone through some sample application

ExcelEport and used the same code

StringBuffer x = new StringBuffer();

String attributeName, headerName;

String entriesName = dataNode.getNodeInfo().getName();

String entryName = entriesName + "Element";

// trim given header texts, so that XML element names adhere to the rule 'no spaces contained'.

trimHeaderTexts(columnInfos);

x.append("<?xml version='1.0' encoding='UTF-8' standalone='no'?> ");

x.append("<").append(entriesName).append("> ");

for (int i = 0; i < dataNode.size(); ++i)

{

IWDNodeElement dataNodeElement = dataNode.getElementAt(i);

x.append("<").append(entryName).append("> ");

for (Iterator iter = columnInfos.keySet().iterator(); iter.hasNext();)

{

attributeName = (String) iter.next();

headerName = (String) columnInfos.get(attributeName);

x

.append("<")

.append(headerName)

.append(">")

.append("<![CDATA[")

.append(dataNodeElement.getAttributeValue(attributeName))

.append("]]>")

.append("</")

.append(headerName)

.append("> ");

}

x.append("</").append(entryName).append("> ");

}

x.append("</").append(entriesName).append("> ");

return x.toString();

iam getting error as type AbstractStringBuilder is not visible

Hi,

Hope in your case, if you choose StringBuffer MWDS returns you a StringBuilder.....

This is because your JRE version no is 1.6(or more than 1.4)... So you ca do two things....

1. Replace all your StringBuffer with String... (Really Dont Sounds good)

or

2. Degrade your JRE to 1.4...

Hi,

I got the same error sometime back. I changed jdk version & problem was solved. Try java version 1.4.
