[JRS gives StreamCorruptedException when using Postgres 8.x driver with Postgres 9.x]

Apparently, 9.x versions of Postgres have a new binary encoding algorithm for LOB fields. This changed a setting’s default value in 9.x (bytea_output); the 8.x driver doesn’t recognize the new encoding, and fails to read the value.

Two workarounds have been suggested:

• Option 1: Use the Postrgres 9.x JDBC driver instead of the 8.x version.
  
• Option 2: Reconfigure postgres instance to use 8.x default value.
  

For Option 2:

1- Edit the <postgres>datapostgresql.conf file.

2 - Locate this line:

    bytea_output = ' hex'          # hex, escape

3 - Change : ' hex' to 'escape'. For example:

    bytea_output = 'escape'          # hex, escape

You need to make this change BEFORE any data is written to the database.

Note that this configuration affects everything in this Postgres instance. If other apps have databases in this Postgres instance, they will also need to be able to handle the ‘escape’ setting for the bytea_output option.

 

[JRS gives StreamCorruptedException when using Postgres 8.x driver with Postgres 9.x]

My JRS repository is hosted by Postgres 9.3, but I need to use an 8.x driver. It’s not working. The application doesn’t load the license properly, and I see some problems in the log like:

java.io.StreamCorruptedException: invalid stream header: XXXXXXXX

 

How can I work around this issue?

[Is it possible to deploy a report into several JasperServer folders ?]

Hi Eric, I don't think there is an automatic way to do this in the server, at least not out-of-the-box/without custmoization.

[Can I use a clone install of JasperReports Server with JBoss AS7/EAP6?]

Thanks for the further info!

[Can I use a clone install of JasperReports Server with JBoss AS7/EAP6?]

 

The short answer is no.

This procedure does not work for JBoss AS7/EAP6 because, in addition to the JasperReports Server web application and the repository contents, Jaspersoft’s buildomatic creates a new module (jaspersoft.org.apache.batik) under the JBoss modules directory.  If this module is not present, deployment will fail.

(Please note that JBoss AS7/EAP6 is not  supported with JasperReports Server versions earlier than 5.1.)

[Can I use a clone install of JasperReports Server with JBoss AS7/EAP6?]

 

Using JBoss 5.1, you can clone your JasperReports Server install  by copying an existing JRS WAR file to a new JBoss instance. While this method isn’t strictly supported, some users have experienced good results.

The question is this: will the same method work when JasperReports Server 5.1 is hosted by JBoss AS7/EAP6?

[Dashboard crashes]

 

In previous versions of the server, using /my_image.jpg worked (3.7-4.x, maybe?). But I just tested in 5.0.1, and you now need to use the full URI to the image on your server. So instead of:

/my_image.jpg 

 

try using: 

http://localhost:8080/jasperserver-pro/my_image.jpg

 

Thanks,

PS - I did have a problem with the spinning disk icon though. 

[Who owns the "Repository Navigator" plug-in?]

Edit: Just realized that you've got another, longer thread on this same topic that seemsto answer my question.

 

Hey Carl,

The plug-in is from Jaspersoft. There's some doc on it in the Pro user guide, but it certainly doesn't cover how to connect via SSH. I've never tried that before, myself, so I don't know what might get in your way.

What kind of errors/behaviors are you seeing?

Thanks,

Kristen

[Repository HTTP API - reserved parameters list]

The ultimate guide is the closest thing I think you'll find to a comprehensive list.

In terms of decorate = no, its behavior varies between different versions of JasperReports server, and in 4.x and above, some users have complained that it doesn't have the expected behavior (see this tracker item). One important detail in the tracker item is the note about using &viewAsDashboardFrame=true instead of decorate = no when working with dashboards.

Please vote for the issue if it's important to you!

Thanks,

[need both 3.7 and 4.0 installed]

I expect what's happening is that when you run the js-import command (intending hit to it your 3.7.0 install) you are actually hitting your 4.0 install. The easiest way to get around this is to stop your 4.0 server before running the import; then js-import will find your 3.7 install instead of your 4.0 install, and you should be in business.

Good luck!

Thanks,

Kristen

[Pre-selecting some values in a multi-select query]

Christian,

I don't know of a way to achieve this out of the box with the server, but it could be done with some (fairly heavy) customizations. You would need to create a custom page for the Add > New Resource > Input Control work-flow as well as adding a new column to the underlying database + all the related logic to write it. And you would also need some custom web work and logic in the run report/schedule report work-flows.

Please log a tracker item for this enhancement.

Thanks,

Kristen

[how to migrate adhoc report from 1 server to another server jasperserver 4.0.1]

You'll need to use the command-line js-export utility. It's documented in install guide and the Pro Admin guide. Or you can use the js-export --help command for info.

On the server host, js-export is in <js-install>/buildomatic directory.

[jasper Server - bundled version mysql crashes]

This doesn't look like somethign specific to analysis. It sounds like there is something wrng with you MySQL instance but it's ahrd to tell without further details.

You should try posting this to the JasperServer forum and see if anyone can give you a hand there. If you;ve already posted there, apologies.

Thanks,

That's exactly right (at least according to my advanced testing of setting the session-timeout to 0 and letting my session sit there for a couple hours without expiring....).

[JasperForge undergoing maintenance this Sat.]

On Saturday, October 30th, Jaspersoft will be making major enhancements to JasperForge. This is a scheduled maintenance window that should last approximately twelve hours between 9:00PM PDT October 30th and 9:00AM PDT October 31st (October 31st 4:00AM and 4:00PM GMT).

Most of the upgrades will not be obvious to users as they are performance related. However, new administrative tools are being introduced, including integration with JasperServer Professional. Project leads will have access to forty canned reports that will help them measure the health of their communities.

 

Thanks,

Kristen

I'm not a coder, but I think you can start by looking at the OlapManagementService class, which implements the flushOlapCache method.

[JasperServer 3.1 compatibility]

I think it depends on what you mean by "compatible." Some iReport 3.7.2 features aren't supported by JasperServer 3.1. For example, I'm quite sure the Table component added in iR 3.7.2 isn't supported by JasperServer 3.1.

Generally, most things will probably work, but the rule of thumb for iR -> JS compatibility is that the version numbers match to the third digit. So iReport 3.7.0 is comppatible with JasperServer 3.7.0.

[LDAP authentication on Windows 2008 Domain Control]

I don't think changing the version of your LDAP server would necessarily cause this to start failing. Perhaps more information about your environment might help. What version of JasperServer are you using? Is that what you used with Win2003 DC?

[Edit welcome page JS 3.7]

The steps you desribe should work, so I'm not sure what to say. Perhaps you need to restart the application?

However, if all you want to do is get rid of the extra info on that page, there's a simple way: JasperServer includes an alternate login page that doesn't include all the extra info. You can use it by editing WEB-INF\jasperserverservlet.xml and changing the login_html prop key to login.jsp. Restart the app and that shoulld be it.

As usual, updating JSPs is getting to the edge of my technical knowledge, but this might get you pointed in the right direction.

[Analysis View with OLAP mondrian cube]

Without more information about your environment, it's going to be hard to diagnose the problem. I'm no expert, but googling "java.security.PrivilegedActionException 401" returned a lot of links that suggest different deployment/configuration for a few different environments.

The simplest suggestion I saw is that the credentials you're passing are wrong. Edit the data source that your view references, and make sure the username and password are correct.

Thanks,

Kristen

[How to disable the cache in Jasper Analysis Views]

On the JasperServer host, locate the mondrian.properties file. It resides in .the WEB-INF directory in your JasperServer installation. In the file, add the following property setting:

mondrian.rolap.star.disableCaching=true.

This turns off caching completely. Disabling caching can have a very noticeable negative performance impact.

Thanks,

Kristen

EDIT: Someone was kind enough to point out my error here - the property needs to be set to TRUE rather than FALSE. Sorry for any confusion.
