Need to change and use Library instance without changing rptlibrary

qos

Hello,

I have a custom data source that has 2 properties. The data source is included in a library and the library is included in a report template.

One of the DS properties has to be changed when generating the report (using RE) but I don't want to save it on file because I can have multiple users asking for the report generation, and each of them will have a different value for the property. I thought that using the method reloadLibrary using library handle instance would work but it doesn't. Can you help me? Here is my code:

List<OdaDataSourceHandle> libDataSources = (List<OdaDataSourceHandle>) library.getAllDataSources();

for(OdaDataSourceHandle odsh : libDataSources){
odsh.setProperty("propertyA", propertyAvalue);
}

(...)

runnable = engine.openReportDesign( template.getFileName());

template.reloadLibrary(library.getLibrary());
IRunAndRenderTask task = engine.createRunAndRenderTask(runnable);
PDFRenderOption options = new PDFRenderOption();
options.setOutputFileName(path);
options.setOutputFormat("pdf");

task.setRenderOption(options);
task.run();
task.close();

I have abandoned this approach and decided to use property binding, still having some problems though. If you can help me i have posted a new topic
