There’s a rather obscure JDeveloper bug that only effects IE7, for af:columns in af:tables that show af:outputText fields based on dates that are null (phew, try and say that with a mouth full of wheaties). It occurs in 11.1.1.4.0 and 11.1.2.0.0 (and all versions in between it’s assumed). In the previous picture from IE7 if you look closely, you’ll notice that the HireDate2 column has lost its border for the null entries. Note the other columns even when they are null, still have a border. If we look under IE8 (or any other browser for that matter) we see the problem doesn’t occur at all: The problem is being caused by 2 separate issues: IE7 does not render borders for HTML table cells (ie. the tag) if the cell contains no data. This can be fixed if the cell contains a   tag. ADF Faces RC includes the   tag for empty table cells, except for null date af:outp... (more)

Apache Ivy and JDeveloper Integration

As software applications grow, a common technique to reduce the complexity is to break the overall solution into separately built and deployed modules. This allows each component to be worked on independently without being overwhelmed with detail, though the cost of reassembling and building the application is the trade off for the added flexibility. When modules become reusable across applications the reassembly and build problem is exasperated and it becomes essential to track which version of each module is required against each application. Such problems can be reduced by the... (more)

One-Way SSL with JAX-WS Using JDeveloper 11gR1 and WLS 10.3.1

A while back Gerard Davison blogged some simple examples of using WS-Security Policies. Gerard's specific example dealt with the WLS policy Wssp1.2-2007-Wss1.1-UsernameToken-Plain-X509-Basic256.xml. As Gerard notes the said policy (further documented in the WLS 10.3.1 doco here) implements user name tokens, encryption of the tokens and signing of the whole SOAP payload. The following post strips back Gerard's example to instead to consider the steps in setting up and testing One-Way SSL for a JAX-WS web service generated via JDeveloper 11gR1 and installed in WLS 10.3.1, using the...

Upgrading WLS Using the Oracle Smart Update Utility

Oracle Journal on Ulitzer Oracle provides the Smart Update utility to upgrade WebLogic Server installations between versions, or to apply specific patches applied by Oracle Support. This post considers upgrading a 10.3.1 server to 10.3.2, not applying patches. As usual your mileage may vary so be diligent in checking these instructions beforehand. The Oracle Smart Update utility is documented here. The general steps to run the Oracle Smart Update utility and upgrade the server are as follows: 1) Ensure your WLS and any managed servers are not running. In turn it would be a good id... (more)

Upgrading WLS via Oracle Support Maintenance Patchsets

Oracle Journal on Ulitzer Recently I blogged about Upgrading WLS using the Oracle Smart Update utility. We discovered that while this utility will happily patch our developers' machines, we had h3lls own trouble trying to get it to work on our server. After much head scratching, gritting of teeth, yelling, begging and sobbing at our firewall administrators, without a solve, we decided a new approach was required. As per Andreas Koop's comment in that original blog post, you can in fact run the Smart Update utility in offline mode, which implies you can download the patches and i... (more)
