ERROR : Invalid byte 1 of 1-byte UTF-8 sequence

For you information,

The only way I have found to fix the problem is to install the following plugin from the Tools > Plugins menu :

XML and Schema
Version : 1.0.1

By installing this plugin, the version of the IDE changed to 1.2.3.

Is it a common problem from the 1.0.2 IDE version ?

I just ran into the same problem.  Saved my report, got out to go to a meeting.  Restarted iReport and got the error.

I installed the Plugin XML and Schema as suggested and...  I don't get the error but now it sits there saying Loading Report in the Report Inspector.

Yeah I had the same problem. You just need to re-do the pattern operation on your currency field and the $ signs will come back to normal.

Probably the pattern changed in the new IDE.

Hi folks,

Hope you are doing fine.

Here is my problem : I work on a report containing a crosstab. That crosstab is populated by a SQL query runned in a dataset. Everything's perfect, but I only have one tiny problem, which is quite annoying. I am unable to hide/remove a full blank line in my crosstab (see the screenshot for more information).

Some will probably say : Why are you adding a blank record in your query results ?
Answer : Well, this is a specific situation. I will try to make it easy to understand. Here we go :

For instance you have a list of laptops in a crosstab. You will need a row group on the serial number, and a column group on the laptops brands.

Let's say you want to list all laptops in a region, for every location/office.

• Office A only has HP and Dell laptops
• Office B only has HP and Lenovo laptops

The problem : You want to show all laptop brands, even if a location doesn't have that laptop brand. (see the second screenshot/image for more information). To achieve it, I add a NULL record in my SQL temp table, representing laptop brands that are missing in the office.

Example : Office A has a NULL record with the Lenovo brand, and Office B has a NULL record with the Dell brand.

This is the only way I found to always print all the columns in the crosstab. Otherwise, the crosstab wasn't showing the NULL columns since it is not available in the SQL query results (raw data).

I just want to hide that null row and eliminate the spacer it creates.

Every field in the crosstab details has Remove Line When Blank checked. As you can see, the line has nothing printed. Now, I just need to hide it for esthetic purpose.

Thank you in advance for help

This also solved my problem thankfully!

However instead of installing the "XML and Schema" plugin, you may just install the "IDE Platform" plugin which is ultimately what solves the problem without having to install the extra plugin unless you need / want it. =)

Hi, I'm using iReport 3.0.0 and using Netbeans 6.5. I've encountered the problem below. The XML and Schema have already installed. May I know what problem do I have? Below are the codes..

net.sf.jasperreports.engine.JRException: com.sun.org.apache.xerces.internal.impl.io.MalformedByteSequenceException: Invalid byte 1 of 1-byte UTF-8 sequence.

Hello ,

I have experianced the same error while runnig reports on Jasperserver.

What I did is to delete those reports from Jasperserver and upload it again,

I know It sound stange but It works for me.

 when we try to replace the reports from IReport to Jasper Repository, Specially in the case of the Main Report which contain the reference of subreport. I think this may be the case where reports are not able to replace completely and it cause that error.

Thanks

Abhishek
