[Known workaround for JDK Bugs?]

 Hi all

we encounter several JDK bugs when using JasperReports:

JDK Bug:

http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6367148

and this one:

Caused by: java.lang.OutOfMemoryError: GC overhead limit exceeded

JDK Bug:

http://bugs.sun.com/view_bug.do?bug_id=6951086

 

Does anyone know workarounds for this? 

I think the first one is a synchronization bug which I can workaround synchronizing the call to "fillReport", what it the other one?

[JasperReport xmla report problems]

Hi Yuna

 

in the URL field, you have to type the url of your analysis server.

 

If your server is at 192.168.0.1, then try

 

http://192.168.0.1/MSAS/msmdpump.dll

[JasperReport xmla report problems]

I got the solution. The property has to look like this:

 

JRProperties.setProperty("net.sf.jasperreports.query.executer.factory.xmla-mdx", "net.sf.jasperreports.engine.query.JRXmlaQueryExecuterFactory");

 

The confusing thing is: this class is not delivered with jasperreports, but with ireport (jar file: cincom-jr-xmla.jar).

 

I'm using jasperreports 1.3.3.

 

Now it works.

[JasperReport xmla report problems]

I managed to solve the first problem by putting the following line before compiling the report:

 

JRProperties.setProperty("net.sf.jasperreports.query.executer.factory.xmla-mdx", "net.sf.jasperreports.olap.xmla.JRXmlaQueryExecuterFactory");

 

 

Additional information to the second problem: the parser gets a

"line 1:1: unexpected token:" for each field in the report.

 

Anyone an idea?

 

Thanks.

[JasperReport xmla report problems]

Hi

 

i try to run a report using a xmla datasource. The report was designed by iReport and works there.

 

If I want to execute the report programmatically, I got the following problems:

 

1) I had to change the <queryString language="mdx"> from xmla-mdx to mdx

 

2) the report does not work (jasperreport cannot map my fields):

 

net.sf.jasperreports.engine.JRRuntimeException: Invalid field mapping "[Date].[Date_Year].[All]".

at net.sf.jasperreports.olap.JROlapDataSource.init(JROlapDataSource.java:248)

at net.sf.jasperreports.olap.JROlapDataSource.<init>(JROlapDataSource.java:113)

at net.sf.jasperreports.olap.xmla.JRXmlaQueryExecuter.createDatasource(JRXmlaQueryExecuter.java:122)

 

..is the example for a field with description Date].[Date_Year].[All].

 

any hints how to solve this problems?

 

thanks a lot
